We present radio observations of the afterglow of the bright gamma-ray burst
GRB980329 made between one month and several years after the burst, a
re-analysis of previously published submillimeter data, and late-time optical
and near-infrared (NIR) observations of the host galaxy. From the absence of a
spectral break in the optical/NIR colors of the host galaxy, we exclude the
earlier suggestion that GRB980329 lies at a redshift of z >~5. We combine our
data with the numerous multi-wavelength observations of the early afterglow,
fit a comprehensive afterglow model to the entire broadband dataset, and derive
fundamental physical parameters of the blast-wave and its host environment.
Models for which the ejecta expand isotropically require both a high
circumburst density and extreme radiative losses from the shock. No low density
model (n << 10 cm^{-3}) fits the data. A burst with a total energy of ~ 10^{51}
erg, with the ejecta narrowly collimated to an opening angle of a few degrees,
driven into a surrounding medium with density ~ 20 cm^{-3}, provides a
satisfactory fit to the lightcurves over a range of redshifts.

A key problem in the field of quantum criticality is to understand the nature
of quantum phase transitions in systems of interacting itinerant fermions,
motivated by experiments on a variety of strongly correlated materials. Much
attention has been paid in recent years to two-dimensional (2D) materials in
which itinerant fermions acquire a pseudo-relativistic Dirac dispersion, such
as graphene, topological insulator surfaces, and certain spin liquids. This
article reviews the phenomenology and theoretical description of quantum phase
transitions in systems of 2D Dirac fermions.

In the 70s a novel branch of statistics emerged focusing its effort in
selecting a function in the pattern recognition problem, which fulfils a
definite relationship between the quality of the approximation and its
complexity. These data-driven approaches are mainly devoted to problems of
estimating dependencies with limited sample sizes and comprise all the
empirical out-of sample generalization approaches, e.g. cross validation (CV)
approaches. Although the latter are \emph{not designed for testing competing
hypothesis or comparing different models} in neuroimaging, there are a number
of theoretical developments within this theory which could be employed to
derive a Statistical Agnostic (non-parametric) Mapping (SAM) at voxel or
multi-voxel level. Moreover, SAMs could relieve i) the problem of instability
in limited sample sizes when estimating the actual risk via the CV approaches,
e.g. large error bars, and provide ii) an alternative way of Family-wise-error
(FWE) corrected p-value maps in inferential statistics for hypothesis testing.
In this sense, we propose a novel framework in neuroimaging based on
concentration inequalities, which results in (i) a rigorous development for
model validation with a small sample/dimension ratio, and (ii) a
less-conservative procedure than FWE p-value correction, to determine the brain
significance maps from the inferences made using small upper bounds of the
actual risk.

Codimension 2 embeddings, algebraic surgery and Seifert forms

The paper contains an error. Main Theorem 2 is false. We are
currently working on fixing the result (it will be more subtle), but it might
take time. To the best of our knowledge Main Theorem 1 is correct and Main
Theorem 3 should be restated in an appropriate way to work

We study the cobordism of manifolds with boundary, and its applications to
codimension 2 embeddings $M^m\subset N^{m+2}$, using the method of the
algebraic theory of surgery. The first main result is a splitting theorem for
cobordisms of algebraic Poincar\'e pairs, which is then applied to describe the
behaviour on the chain level of Seifert surfaces of embeddings $M^{2n-1}
\subset S^{2n+1}$ under isotopy and cobordism. The second main result (update:
which is false) is that the $S$-equivalence class of a Seifert form is an
isotopy invariant of the embedding, generalizing the Murasugi--Levine result
for knots and links. The third main result is a generalized Murasugi--Kawauchi
inequality giving an upper bound on the difference of the Levine--Tristram
signatures of cobordant embeddings.

The aim of this work is to asses simultaneous spectrum access situations that
may occur in Cognitive Radio (CR) environments. The approach is that of one
shot, noncooperative games describing CR interactions. Open spectrum access
scenarios are modelled based on continuous and discrete reformulations of the
Cournot game theoretical model. CR interaction situations are described by Nash
and Pareto equilibria. Also, the heterogeneity of players is captured by the
new concept of joint Nash-Pareto equilibrium, allowing CRs to be biased toward
different types of equilibrium. Numerical simulations reveal equilibrium
situations that may be reached in simultaneous access scenarios of two and
three users.

Density of Composite Places in Function Fields and Applications to Real
Holomorphy Rings

Given an algebraic function field $F|K$ and a place $\wp$ on $K$, we prove
that the places that are composite with extensions of $\wp$ to finite
extensions of $K$ lie dense in the space of all places of $F$, in a strong
sense. We apply the result to the case of $K=R$ any real closed field and the
fixed place on $R$ being its natural (finest) real place. This leads to a new
description of the real holomorphy ring of $F$ which can be seen as an analogue
to a certain refinement of Artin's solution of Hilbert's 17th problem. We also
determine the relation between the topological space $M(F)$ of all $\R$-places
of $F$ (places with residue field contained in $\R$), its subspace of all
$\R$-places of $F$ that are composite with the natural $\R$-place of $R$, and
the topological space of all $R$-rational places. Further results about these
spaces as well as various classes of relative real holomorphy rings are proven.
At the conclusion of the paper the theory of real spectra of rings will be
applied to interpret basic concepts from that angle and to show that the space
$M(F)$ has only finitely many topological components.

Growth on transition metal substrates is becoming a method of choice to
prepare large-area graphene foils. In the case of nickel, where carbon has a
significant solubility, such a growth process includes at least two elementary
steps: (1) carbon dissolution into the metal, and (2) graphene precipitation at
the surface. Here, we dissolve calibrated amounts of carbon in nickel films,
using carbon ion implantation, and annealing at 725 \circ or 900 \circ. We then
use transmission electron microscopy to analyse the precipitation process in
detail: the latter appears to imply carbon diffusion over large distances and
at least two distinct microscopic mechanisms.

Eigenspectra of the SDSS DR1 quasars

We construct eigenspectra from the DR1 quasars in the SDSS using the
Karhunen-Lo\`eve (KL) transform (or Principal Component Analysis, PCA) in
different redshift and luminosity bins. We find that the quasar spectra can be
classified, by the first two eigenspectra, into a continuous sequence in the
variation of the spectral slope. We also find a dependence on redshift and
luminosity in the eigencoefficients. The dominant redshift effect is the
evolution of the blended Fe~II emission (optical) and the Balmer continuum (the
``small-bump'', $\lambda_{rest} \approx 2000-4000$\AA), while the luminosity
effect is related to the Baldwin effect. Correlations among several major broad
emission lines are found, including the well-known ``Eigenvector-1''.

A new enlightenment about gaps between primes

http://arxiv.org/licenses/nonexclusive-distrib/1.0/

The idea of generating prime numbers through sequence of sets of co-primes
was the starting point of this paper that ends up by proving two conjectures,
the existence of infinitely many twin primes and the Goldbach conjecture. The
main idea of our approach is summarized on the creation and on the analyzing
sequence of sets of distinct co-primes with the first $n$ primes, $\left\{ p_i
:\, i\leq n \right\}$, and the important properties of the modulus linear
combination of the co-prime sets, $H=\left(1,p_{n+1},..., \Pi_{i=1}^n
p_i-1\right) $, that gives sets of even numbers $\{0,2,4,..., \Pi_{i=1}^n p_i
-2 \}$. Furthermore, by generalizing our approach, the Polignac conjecture "the
existence of infinitely many cousin primes, $p_{n+1}-p_{n}=4$," and the
statement that "every even integer can be expressed as a difference of two
primes," are derived as well.

The 1<z<2 redshift window hosts the peak of the star formation and metal
production rates. Studies of the metal content of the star forming galaxies at
these epochs are however sparse. We report VLT-ISAAC near-infrared spectroscopy
for a sample of five [OII]-selected, M_B,AB<-21.5, z~1.4 galaxies, by which we
measured Hbeta and [OIII]5007 emission line fluxes from J-band spectra, and
Halpha line fluxes plus upper limits for [NII]6584 fluxes from H-band spectra.
The z~1.4 galaxies are characterized by the high [OIII]/[OII] line ratios, low
extinction and low metallicity that are typical of lower luminosity CADIS
galaxies at 0.4<z<0.7, and of more luminous Lyman Break Galaxies at z~3, but
not seen in CFRS galaxies at 0.4<z<0.9. This type of spectrum (e.g., high
[OIII]/[OII]) is seen in progressively more luminous galaxies as the redshift
increases. These spectra are caused by a combination of high ionisation
parameter q and lower [O/H]. Pegase2 chemical evolution models are used to
relate the observed metallicities and luminosities of z~1.4 galaxies to galaxy
samples at lower and higher redshift. Not surpringsingly, we see a relationship
between redshift and inferred chemical age. We suppose that the metal-enriched
reservoirs of star forming gas that we are probing at intermediate redshifts
are being mostly consumed to build up both the disk and the bulge components of
spiral galaxies. Finally, our analysis of the metallicity-luminosity relation
at 0<z<1.5 suggests that the period of rapid chemical evolution may take place
progressively in lower mass systems as the universe ages. These results are
consistent with a ``downsizing'' type picture in the sense that particular
signatures (e.g., high [OIII]/[OII] or low [O/H]) are seen in progressively
more luminous (massive) systems at higher redshifts.

We consider in this review the statistical mechanical description of a very
general microscopic lattice model of a compressible and interacting
multi-component mixture of linear polymers of fixed lengths. The model contains
several microscopic, i.e. bare parameters determining the thermodynamic state
of the system. General arguments are given to show that these parameters must
be independent not only of the lattice properties but also of the thermodynamic
state, and that the voids representing free volume must be carefully treated,
if thermodynamics has to be properly obeyed. These facts have not always been
appreciated in the literature. We focus on mixing functions, some of which have
not been properly calculated in the literature. In general, mixing is
non-isometric (non-zero volume of mixing) and the entropy of mixing is
non-ideal. We have recently developed a lattice theory for the general model,
which goes beyond the random mixing approximation (RMA) limit and is
thermodynamically consistent in the entire parameter space. The theory contains
terms that do not have a continuum analog except in the RMA limit or for
point-like particles. Both the free volume and the total volume determine the
thermodynamics of the system. The RMA limit of our theory gives rise to a new
theory, which can be taken as the extension of the conventional incompressible
Flory-Huggins theory and is similar in simplicity. Using our complete theory,
we calculate the effects of size disparity and interactions on the
thermodynamics of the model. Cohesive energies are not constant in general.
Non-isometry can make the energy of mixing negative, even when all exchange
interactions are repulsive. Consequently, Scatchard-Hildebrand theory cannot be
substantiated in general. Various unusual features are noted and discussed.

The method of topological vertex for topological string theory on toric
Calabi-Yau 3-folds is reviewed. Implications of an explicit formula of
partition functions in the "on-strip" case, typically the generalized
conifolds, are considered. Generating functions of part of the partition
functions are shown to be tau functions of the KP hierarchy. The associated
Baker-Akhiezer functions play the role of wave functions, and satisfy
$q$-difference equations. These $q$-difference equations represent the quantum
mirror curves conjectured by Gukov and Su{\l}kowski.

Quantum light-matter interfaces, based upon ensembles of cold atoms or other
quantum emitters, are a vital platform for diverse quantum technologies and the
exploration of fundamental quantum phenomena. Most of our understanding and
modeling of such systems are based upon macroscopic theories, wherein the atoms
are treated as a smooth, quantum polarizable medium. Although it is known that
such approaches ignore a number of microscopic details, such as the granularity
of atoms, dipole-dipole interactions and multiple scattering of light, the
consequences of such effects in practical settings are usually mixed with
background macroscopic effects and difficult to quantify. In this work we
demonstrate a time-domain method to measure microscopically-driven optical
effects in a background-free fashion, by transiently suppressing the
macroscopic dynamics. With the method, we reveal a microscopic dipolar
dephasing mechanism that generally limits the lifetime of the optical spin-wave
order in a random gas. Theoretically, we show the dephasing effect emerges from
the strong resonant dipole interaction between close-by atomic pairs.

The CoRoT satellite exoplanetary team announces its sixth transiting planet
in this paper. We describe and discuss the satellite observations as well as
the complementary ground-based observations - photometric and spectroscopic -
carried out to assess the planetary nature of the object and determine its
specific physical parameters. The discovery reported here is a `hot Jupiter'
planet in an 8.9d orbit, 18 stellar radii, or 0.08 AU, away from its primary
star, which is a solar-type star (F9V) with an estimated age of 3.0 Gyr. The
planet mass is close to 3 times that of Jupiter. The star has a metallicity of
0.2 dex lower than the Sun, and a relatively high $^7$Li abundance. While
thelightcurveindicatesamuchhigherlevelof activity than, e.g., the Sun, there is
no sign of activity spectroscopically in e.g., the [Ca ] H&K lines.

What is Wrong with One-Class Anomaly Detection?
| null | null | null | null |

From a safety perspective, a machine learning method embedded in real-world
applications is required to distinguish irregular situations. For this reason,
there has been a growing interest in the anomaly detection (AD) task. Since we
cannot observe abnormal samples for most of the cases, recent AD methods
attempt to formulate it as a task of classifying whether the sample is normal
or not. However, they potentially fail when the given normal samples are
inherited from diverse semantic labels. To tackle this problem, we introduce a
latent class-condition-based AD scenario. In addition, we propose a
confidence-based self-labeling AD framework tailored to our proposed scenario.
Since our method leverages the hidden class information, it successfully avoids
generating the undesirable loose decision region that one-class methods suffer.
Our proposed framework outperforms the recent one-class AD methods in the
latent multi-class scenarios.

Extra-dimensional theories contain additional degrees of freedom related to
the geometry of the extra space which can be interpreted as new particles. Such
theories allow to reformulate most of the fundamental problems of physics from
a completely different point of view. In this essay we concentrate on the brane
fluctuations which are present in brane-worlds, and how such oscillations of
the own space-time geometry along curved extra dimensions can help to resolve
the Universe missing mass problem. The energy scales involved in these models
are low compared to the Planck scale, and this means that some of the brane
fluctuations distinctive signals could be detected in future colliders and in
direct or indirect dark matter searches.

Knowledge of quantum mechanical systems is becoming more important for many
science and engineering students who are looking to join the emerging quantum
workforce. To better prepare a wide range of students for these careers, we
must seek to develop new tools to enhance our education in quantum topics. We
present initial studies on the use of one of these such tools, Quantum
Composer, a 1D quantum simulation and visualization tool developed for
education and research purposes. In particular, we conducted five think-aloud
interviews with students who worked through an exercise using Quantum Composer
that focused on the statics and dynamics of quantum states in a single harmonic
well system. Our results show that Quantum Composer helps students to obtain
the correct answers to the questions posed, but additional support is needed to
facilitate the development of student reasoning behind these answers. We also
show that students are able to focus only on the relevant features of Quantum
Composer to achieve the task.

We consider an explicitly solvable model (formulated in the Riemannian
geometry terms) for a stationary wave process in a specific thin domain with
the Dirichlet boundary conditions on the boundary of the domain. The transition
from the solutions of the scattering problem to the solutions of a problem on
the limiting quantum graph is studied. We calculate the Lagrangian gluing
conditions at vertices for the problem on the limiting graph. If the frequency
of the incident wave is above the bottom of the absolutely continuous spectrum,
the gluing conditions are formulated in terms of the scattering data of a
problem in a neighborhood of each vertex. Near the bottom of the absolutely
continuous spectrum the wave propagation is generically suppressed, and the
gluing condition is degenerate (any solution of the limiting problem is zero at
each vertex).

The equation of state of strange matter build of the u,d,s quarks in the
framework of the MIT bag model is studied. The scaling relations with bag
constant are discussed and applied to the determination of maximum frequency of
a particle in stable circular orbit around strange star. The highest QPO
frequency of 1.33 kHz observed so far is consistent with the strange stars
models for which the maximum QPO frequency is 1.7-2.4 kHz depending on the
strange quark mass and the QCD coupling constant. The linear approximation of
the equation of state is found and the parameters of this EOS are determined as
a functions of strange quark mass, QCD coupling constant and bag constant. This
approximation reproduces exact results within an error of the order of 1% and
can be used for the complete study of the properties of strange stars including
microscopic stability of strange matter and determination of the total baryon
number of the star.

Learning to See Analogies: A Connectionist Exploration

This dissertation explores the integration of learning and analogy-making
through the development of a computer program, called Analogator, that learns
to make analogies by example. By "seeing" many different analogy problems,
along with possible solutions, Analogator gradually develops an ability to make
new analogies. That is, it learns to make analogies by analogy. This approach
stands in contrast to most existing research on analogy-making, in which
typically the a priori existence of analogical mechanisms within a model is
assumed. The present research extends standard connectionist methodologies by
developing a specialized associative training procedure for a recurrent network
architecture. The network is trained to divide input scenes (or situations)
into appropriate figure and ground components. Seeing one scene in terms of a
particular figure and ground provides the context for seeing another in an
analogous fashion. After training, the model is able to make new analogies
between novel situations. Analogator has much in common with lower-level
perceptual models of categorization and recognition; it thus serves as a
unifying framework encompassing both high-level analogical learning and
low-level perception. This approach is compared and contrasted with other
computational models of analogy-making. The model's training and generalization
performance is examined, and limitations are discussed.

Generalized quantum geometric tensor for excited states using the path

The quantum geometric tensor, composed of the quantum metric tensor and Berry
curvature, fully encodes the parameter space geometry of a physical system. We
first provide a formulation of the quantum geometrical tensor in the path
integral formalism that can handle both the ground and excited states, making
it useful to characterize excited state quantum phase transitions (ESQPT). In
this setting, we also generalize the quantum geometric tensor to incorporate
variations of the system parameters and the phase-space coordinates. This gives
rise to an alternative approach to the quantum covariance matrix, from which we
can get information about the quantum entanglement of Gaussian states through
tools such as purity and von Neumann entropy. Second, we demonstrate the
equivalence between the formulation of the quantum geometric tensor in the path
integral formalism and other existing methods. Furthermore, we explore the
geometric properties of the generalized quantum metric tensor in depth by
calculating the Ricci tensor and scalar curvature for several quantum systems,
providing insight into this geometric information.

The geometry of a two-dimensional surface in a curved space can be most
easily visualized by using an isometric embedding in flat three-dimensional
space. Here we present a new method for embedding surfaces with spherical
topology in flat space when such a embedding exists. Our method is based on
expanding the surface in spherical harmonics and minimizing for the differences
between the metric on the original surface and the metric on the trial surface
in the space of the expansion coefficients. We have applied this method to
study the geometry of back hole horizons in the presence of strong,
non-axisymmetric, gravitational waves (Brill waves). We have noticed that, in
many cases, although the metric of the horizon seems to have large deviations
from axisymmetry, the intrinsic geometry of the horizon is almost axisymmetric.
The origin of the large apparent non-axisymmetry of the metric is the
deformation of the coordinate system in which the metric was computed.

We apply a previously developed scheme to consistently include the improved
saturation model for the unintegrated gluon distribution (UGD) in order to
evaluate, in the framework of $k_{t}$ factorization, at small $x$ at the
next-to-leading order (NLO) in $\alpha_{s}$. We start the unintegrated gluon
distribution with a parametrization of the deep inelastic structure function
for electromagnetic scattering with protons, and then extract the color dipole
cross section, which preserves its behavior success in a wide range of
$k_{t}^{2}$ in comparisons with the UGD models (M. Hentschinski, A. Sabio Vera
and C. Salas (HSS), I.P.Ivanov and N.N.Nikolaev (IN) and G. Watt, A.D. Martin
and M.G. Ryskin (WMR)) . These results show that the geometric scaling holds
for the improved saturation model in a wide kinematic region $rQ_{s}$, and
are comparable with the Golec-Biernat-W$\ddot{\mathrm{u}}$sthoff (GBW) model.
The unintegrated gluon distribution at low and high momentum transfer in a
wide
range of $x$ is considered.

In this work, we present a performance analysis of Field Effect Transistors
based on recently fabricated 100% hydrogenated graphene (the so-called
graphane) and theoretically predicted semi-hydrogenated graphene (i.e.
graphone). The approach is based on accurate calculations of the energy bands
by means of GW approximation, subsequently fitted with a three-nearest neighbor
(3NN) sp3 tight-binding Hamiltonian, and finally used to compute ballistic
transport in transistors based on functionalized graphene. Due to the large
energy gap, the proposed devices have many of the advantages provided by
one-dimensional graphene nanoribbon FETs, such as large Ion and Ion/Ioff
ratios, reduced band-to-band tunneling, without the corresponding disadvantages
in terms of prohibitive lithography and patterning requirements for circuit
integration.

Imaginary Voice: Face-styled Diffusion Model for Text-to-Speech

The goal of this work is zero-shot text-to-speech synthesis, with speaking
styles and voices learnt from facial characteristics. Inspired by the natural
fact that people can imagine the voice of someone when they look at his or her
face, we introduce a face-styled diffusion text-to-speech (TTS) model within a
unified framework learnt from visible attributes, called Face-TTS. This is the
first time that face images are used as a condition to train a TTS model.
We jointly train cross-model biometrics and TTS models to preserve speaker
identity between face images and generated speech segments. We also propose a
speaker feature binding loss to enforce the similarity of the generated and the
ground truth speech segments in speaker embedding space. Since the biometric
information is extracted directly from the face image, our method does not
require extra fine-tuning steps to generate speech from unseen and unheard
speakers. We train and evaluate the model on the LRS3 dataset, an in-the-wild
audio-visual corpus containing background noise and diverse speaking styles.

We study the asymptotic stability of a dissipative evolution in a Hilbert
space subject to intermittent damping. We observe that, even if the
intermittence satisfies a persistent excitation condition, if the Hilbert space
is infinite-dimensional then the system needs not being asymptotically stable
(not even in the weak sense). Exponential stability is recovered under a
generalized observability inequality, allowing for time-domains that are not
intervals. Weak asymptotic stability is obtained under a similarly generalized
unique continuation principle. Finally, strong asymptotic stability is proved
for intermittences that do not necessarily satisfy some persistent excitation
condition, evaluating their total contribution to the decay of the trajectories
of the damped system. Our results are discussed using the example of the wave
equation, Schr\"odinger's equation and, for strong stability, also the special
case of finite-dimensional systems.

Fluctuations of the color superconducting order parameter in dense quark
matter at finite temperatures are investigated in terms of the phenomenological
Ginzburg - Landau approach. Our estimates show that fluctuations of the
di-quark gap may strongly affect some of thermodynamic quantities even far
below and above the critical temperature. If the critical temperature of the
di-quark phase transition were rather high one could expect a manifestation of
fluctuations of the di-quark gap in the course of heavy ion collisions.

In class-incremental semantic segmentation, we have no access to the labeled
data of previous tasks. Therefore, when incrementally learning new classes,
deep neural networks suffer from catastrophic forgetting of previously learned
knowledge. To address this problem, we propose to apply a self-training
approach that leverages unlabeled data, which is used for the rehearsal of
previous knowledge. Specifically, we first learn a temporary model for the
current task, and then pseudo labels for the unlabeled data are computed by
fusing information from the old model of the previous task and the current
temporary model. Additionally, conflict reduction is proposed to resolve the
conflicts of pseudo labels generated from both the old and temporary models. We
show that maximizing self-entropy can further improve results by smoothing the
overconfident predictions. Interestingly, in the experiments we show that the
auxiliary data can be different from the training data and that even
general-purpose but diverse auxiliary data can lead to large performance gains.
The experiments demonstrate state-of-the-art results: obtaining a relative gain
of up to 114% on Pascal-VOC 2012 and 8.5% on the more challenging ADE20K
compared to previous state-of-the-art methods.

We prove a holographic c-theorem for the a central charge in AdS/CFT where
the bulk is described by a gravitational action built out of an arbitrary
function f(R^{ab}_{cd}) of the Riemann tensor coupled to bulk matter. This
theorem holds provided a generalized null energy condition involving both
matter and higher curvature gravitational interactions is satisfied. As an
example, we consider the case of a curvature-squared action, and find that
generically the generalized null energy condition involves not just the bulk
matter, but also the sign of R" where a prime denotes a radial derivative and
where R is the bulk scalar curvature.

We study here global and local entanglements of open protein chains by
implementing the concept of knotoids. Knotoids have been introduced in 2012 by
Vladimir Turaev as a generalization of knots in 3-dimensional space. More
precisely, knotoids are diagrams representing projections of open curves in 3D
space, in contrast to knot diagrams which represent projections of closed
curves in 3D space. The intrinsic difference with classical knot theory is that
the generalization provided by knotoids admits non-trivial topological
entanglement of the open curves provided that their geometry is frozen as it is
the case for crystallized proteins. Consequently, our approach doesn't require
the closure of chains into loops which implies that the geometry of analysed
chains does not need to be changed by closure in order to characterize their
topology. Our study revealed that the knotoid approach detects protein regions
that were classified earlier as knotted and also new, topologically interesting
regions that we classify as pre-knotted.

We introduce a variant of continuous random cascade models that extends
former constructions introduced by Barral-Mandelbrot and Bacry-Muzy in the
sense that they can be supported by sets of arbitrary fractal dimension. The so
introduced sets are exactly self-similar stationary versions of random Cantor
sets formerly introduced by Mandelbrot as "random cutouts". We discuss the main
mathematical properties of our construction and compute its scaling properties.
We then illustrate our purpose on several numerical examples and we consider a
possible application to rainfall data. We notably show that our model allows us
to reproduce remarkably the distribution of dry period durations.

This contribution focuses on two-party negotiation over continuous issues. We
firstly prove two drawbacks of the jointly Improving Direction Method (IDM),
namely that IDM is not a Strategy-Proof (SP) nor an Information Concealing (IC)
method. Thus we prove that the concurrent lack of these two properties implies
the actual non-efficiency of IDM. Finally we propose a probabilistic method
which is both IC and stochastically SP thus leading to efficient settlements
without being affected by manipulatory behaviors.

By extending our general spin-current model to non-centrosymmetric spin
dimers and performing density functional calculations, we investigate the
causes for the helical magnetic order and the origin of the giant ferroelectric
polarization of CaMn7O12. The giant ferroelectric polarization is proposed to
be caused by the symmetric exchange striction due to the canting of the Mn4+
spin arising from its strong Dzyaloshinskii-Moriya (DM) interaction. Our study
suggests that CaMn7O12 may exhibit a novel magnetoelectric coupling mechanism
in which the magnitude of the polarization is governed by the exchange
striction, but the direction of the polarization by the chirality of the
helical magnetic order.

XFT: Practical Fault Tolerance Beyond Crashes
| null | null | null | null |
cs.DC
|
http://arxiv.org/licenses/nonexclusive-distrib/1.0/
|
Despite years of intensive research, Byzantine fault-tolerant (BFT) systems
have not yet been adopted in practice. This is due to additional cost of BFT in
terms of resources, protocol complexity and performance, compared with crash
fault-tolerance (CFT). This overhead of BFT comes from the assumption of a
powerful adversary that can fully control not only the Byzantine faulty
machines, but at the same time also the message delivery schedule across the
entire network, effectively inducing communication asynchrony and partitioning
otherwise correct machines at will. To many practitioners, however, such strong
attacks appear irrelevant.
In this paper, we introduce cross fault tolerance or XFT, a novel approach to
building reliable and secure distributed systems and apply it to the classical
state-machine replication (SMR) problem. In short, an XFT SMR protocol provides
the reliability guarantees of widely used asynchronous CFT SMR protocols such
as Paxos and Raft, but also tolerates Byzantine faults in combination with
network asynchrony, as long as a majority of replicas are correct and
communicate synchronously. This allows the development of XFT systems at the
price of CFT (already paid for in practice), yet with strictly stronger
resilience than CFT --- sometimes even stronger than BFT itself.
As a showcase for XFT, we present XPaxos, the first XFT SMR protocol, and
deploy it in a geo-replicated setting. Although it offers much stronger
resilience than CFT SMR at no extra resource cost, the performance of XPaxos
matches that of the state-of-the-art CFT protocols.

We present the results of Monte Carlo simulations for the critical dynamics
of the three-dimensional site-diluted quenched Ising model. Three different
dynamics are considered, these correspond to the local update Metropolis scheme
as well as to the Swendsen-Wang and Wolff cluster algorithms. The lattice sizes
of L=10-96 are analysed by a finite-size-scaling technique. The site dilution
concentration p=0.85 was chosen to minimize the correction-to-scaling effects.
We calculate numerical values of the dynamical critical exponents for the
integrated and exponential autocorrelation times for energy and magnetization.
As expected, cluster algorithms are characterized by lower values of dynamical
critical exponent than the local one: also in the case of dilution critical
slowing down is more pronounced for the Metropolis algorithm. However, the
striking feature of our estimates is that they suggest that dilution leads to
decrease of the dynamical critical exponent for the cluster algorithms. This
phenomenon is quite opposite to the local dynamics, where dilution enhances
critical slowing down.

Transitive Invariance for Self-supervised Visual Representation Learning
|
ICCV 2017
| null | null | null |

|
http://arxiv.org/licenses/nonexclusive-distrib/1.0/
|
Learning visual representations with self-supervised learning has become
popular in computer vision. The idea is to design auxiliary tasks where labels
are free to obtain. Most of these tasks end up providing data to learn specific
kinds of invariance useful for recognition. In this paper, we propose to
exploit different self-supervised approaches to learn representations invariant
to (i) inter-instance variations (two objects in the same class should have
similar features) and (ii) intra-instance variations (viewpoint, pose,
deformations, illumination, etc). Instead of combining two approaches with
multi-task learning, we argue to organize and reason the data with multiple
variations. Specifically, we propose to generate a graph with millions of
objects mined from hundreds of thousands of videos. The objects are connected
by two types of edges which correspond to two types of invariance: "different
instances but a similar viewpoint and category" and "different viewpoints of
the same instance". By applying simple transitivity on the graph with these
edges, we can obtain pairs of images exhibiting richer visual invariance. We
use this data to train a Triplet-Siamese network with VGG16 as the base
architecture and apply the learned representations to different recognition
tasks. For object detection, we achieve 63.2% mAP on PASCAL VOC 2007 using Fast
R-CNN (compare to 67.3% with ImageNet pre-training). For the challenging COCO
dataset, our method is surprisingly close (23.5%) to the ImageNet-supervised
counterpart (24.4%) using the Faster R-CNN framework. We also show that our
network can perform significantly better than the ImageNet network in the
surface normal estimation task.

Extreme events and their optimal mitigation in nonlinear structural
systems excited by stochastic loads: Application to ocean engineering systems

We develop an efficient numerical method for the probabilistic quantification
of the response statistics of nonlinear multi-degree-of-freedom structural
systems under extreme forcing events, emphasizing accurate heavy-tail
statistics. The response is decomposed to a statistically stationary part and
an intermittent component. The stationary part is quantified using a
statistical linearization method while the intermittent part, associated with
extreme transient responses, is quantified through i) either a few carefully
selected simulations or ii) through the use of effective measures (effective
stiffness and damping). The developed approach is able to accurately capture
the extreme response statistics orders of magnitude faster compared with direct
methods. The scheme is applied to the design and optimization of small
attachments that can mitigate and suppress extreme forcing events delivered to
a primary structural system. Specifically, we consider the problem of
suppression of extreme responses in two prototype ocean engineering systems.
First, we consider linear and cubic springs and perform parametric optimization
by minimizing the forth-order moments of the response. We then consider a more
generic, possibly asymmetric, piecewise linear spring and optimize its
nonlinear characteristics. The resulting asymmetric spring design far
outperforms the optimal cubic energy sink and the linear tuned mass dampers.

This paper introduces the notion of measure representation of DNA sequences.
Spectral analysis and multifractal analysis are then performed on the measure
representations of a large number of complete genomes. The main aim of this
paper is to discuss the multifractal property of the measure representation and
the classification of bacteria. From the measure representations and the values
of the $D_{q}$ spectra and related $C_{q}$ curves, it is concluded that these
complete genomes are not random sequences. In fact, spectral analyses performed
indicate that these measure representations considered as time series, exhibit
strong long-range correlation. For substrings with length K=8, the $D_{q}$
spectra of all organisms studied are multifractal-like and sufficiently smooth
for the $C_{q}$ curves to be meaningful. The $C_{q}$ curves of all bacteria
resemble a classical phase transition at a critical point. But the 'analogous'
phase transitions of chromosomes of non-bacteria organisms are different. Apart
from Chromosome 1 of {\it C. elegans}, they exhibit the shape of double-peaked
specific heat function.

I introduce a very simple method to defend against adversarial examples. The
basic idea is to raise the slope of the ReLU function at the test time.
Experiments over MNIST and CIFAR-10 datasets demonstrate the effectiveness of
the proposed defense against a number of strong attacks in both untargeted and
targeted settings. While perhaps not as effective as the state of the art
adversarial defenses, this approach can provide insights to understand and
mitigate adversarial attacks. It can also be used in conjunction with other
defenses.

We investigate the attractor mechanism for spherically symmetric extremal
black holes in a theory of general $R^2$ gravity in 4-dimensions, coupled to
gauge fields and moduli fields. For the general $R^2$ theory, we look for
solutions which are analytic near the horizon, show that they exist and enjoy
the attractor behavior. The attractor point is determined by extremization of
an effective potential at the horizon. This analysis includes the backreaction
and supports the validity of non-supersymmetric attractors in the presence of
higher derivative interactions. To include a wider class of solutions, we
continue our analysis for the specific case of a Gauss-Bonnet theory which is
non-topological, due to the coupling of Gauss-Bonnet terms to the moduli
fields. We find that the regularity of moduli fields at the horizon is
sufficient for attractor behavior. For the non-analytic sector, this regularity
condition in turns implies the minimality of the effective potential at the
attractor point.

Galactic black hole candidate (BHC) GX~339-4 underwent several outbursting
phases in the past two and a half decades at irregular intervals of $2-3$
years. Nature of these outbursts in terms of the duration, number of peaks,
maximum peak intensity, etc. varies. We present a possible physical reason
behind the variation of outbursts. From a physical point of view, if the supply
of matter from the companion is roughly constant, the total energy release in
an outburst is expected to be proportional to the quiescence period prior to
the outburst when the matter is accumulated. We use archival data of RXTE/ASM
from January 1996 to June 2011, and MAXI/GSC from August 2009 to July 2020
data. Initial five outbursts of GX~339-4 between 1997 and 2011 were observed by
ASM and showed a good linear relation between the accumulation period and the
amount of energy released in each outburst, but the outbursts after 2013
behaved quite differently. The 2013, $2017-18$, and $2018-19$ outbursts were of
short duration, and incomplete or `failed' in nature. We suggest that the
matter accumulated during the quiescence periods prior to these outbursts were
not cleared through accretion due to lack of viscosity. The leftover matter was
cleared in the immediate next outbursts. Our study thus sheds light on long
term accretion dynamics in outbursting sources.

Metal Abundances of KISS Galaxies. IV. Galaxian Luminosity-Metallicity

We explore the galaxian luminosity-metallicity (L-Z) relationship in both the
optical and the near-IR using a combination of optical photometric and
spectroscopic observations from the KPNO International Spectroscopic Survey
(KISS) and near-infrared photometry from the Two-micron All Sky Survey (2MASS).
We supplement the 2MASS data with our own NIR photometry for a small number of
lower-luminosity ELGs that are under-represented in the 2MASS database. Our
B-band L-Z relationship includes 765 star-forming KISS galaxies with coarse
abundance estimates from our follow-up spectra, while the correlation with KISS
and 2MASS yields a total of 420 galaxies in our J-band L-Z relationship. We
explore the effect that changing the correlation between the strong-line
abundance diagnostic R_23 and metallicity has on the derived L-Z relation. We
find that the slope of the L-Z relationship decreases as the wavelength of the
luminosity bandpass increases. We interpret this as being, at least in part, an
effect of internal absorption in the host galaxy. Furthermore, the dispersion
in the L-Z relation decreases for the NIR bands, suggesting that variations in
internal absorption contribute significantly to the observed scatter. We
propose that our NIR L-Z relations are more fundamental than the B-band
relation, since they are largely free of absorption effects and the NIR
luminosities are more directly related to the stellar mass of the galaxy than
are the optical luminosities.

We study the optimal order placement strategy with the presence of a
liquidity cost. In this problem, a stock trader wishes to clear her large
inventory by a predetermined time horizon $T$. A trader uses both limit and
market orders, and a large market order faces an adverse price movement caused
by the liquidity risk. First, we study a single period model where the trader
places a limit order and/or a market order at the beginning. We show the
behavior of optimal amount of market order, $m^*$, and optimal placement of
limit order, $y^*$, under different market conditions. Next, we extend it to a
multi-period model, where the trader makes sequential decisions of limit and
market orders at multiple time points.

The necessary and sufficient conditions for a three-dimensional Riemannian
metric to admit a transitive group of isometries are obtained. These conditions
are Intrinsic, Deductive, Explicit and ALgorithmic, and they offer an IDEAL
labeling of these geometries. It is shown that the transitive action of the
group naturally falls into an unfolding of some of the ten types in the
Bianchi-Behr classification. Explicit conditions, depending on the Ricci
tensor, are obtained that characterize all these types.

Certain type II string non-threshold BPS bound states are shown to be related
to non-static backgrounds in 11-dimensional theory. The 11-d counterpart of the
bound state of NS-NS and R-R type IIB strings wound around a circle is a pure
gravitational wave propagating along a generic cycle of 2-torus. The extremal
(q_1,q_2) string with non-vanishing momentum along the circle (or infinitely
boosted black string) corresponds in D=11 to a 2-brane wrapped around 2-torus
with momentum flow along the (q_1,q_2) cycle. Applying duality transformations
to the string-string solution we find type IIA background representing a bound
state of 2-brane and 0-brane. Its lift to 11 dimensions is simply a 2-brane
finitely boosted in transverse direction. This 11-d solution interpolates
between a static 2-brane (zero boost) and a gravitational wave in 11-th
dimension (infinite boost). Similar interpretations are given for various bound
states involving 5-branes. Relations between transversely boosted M-branes and
1/2 supersymmetric non-threshold bound states 2+0 and 5+0 complement relations
between M-branes with momentum in longitudinal direction and 1/4 supersymmetric
threshold bound states 1+0 and 4+0. In the second part of the paper we
establish the correspondence between the BPS states of type IIB strings on a
circle and oscillating states of a fundamental supermembrane wrapped around a
2-torus. We show that the (q_1,q_2) string spectrum is reproduced by the
membrane BPS spectrum, determined using a certain limit. This supports the
picture suggested by Schwarz.

We consider the general character of the spatial distribution of a population
that grows through reproduction and subsequent local resettlement of new
population members. We present several simple one and two-dimensional point
placement models to illustrate possible generic behavior of these
distributions. We show, numerically and analytically, that these models all
lead to multifractal spatial distributions of population. Additionally, we make
qualitative links between our models and the example of the Earth at Night
image, showing the Earth's nighttime man-made light as seen from space. The
Earth at Night data suffer from saturation of the sensing photodetectors at
high brightness (`clipping'), and we account for how this influences the
determined dimension spectrum of the light intensity distribution.

In a general decay chain $A\to B_1B_2\to C_1C_2\ldots$, we prove that the
angular correlation function $I(\theta_1,\theta_2,\phi_+)$ in the decay of
$B_{1,2}$ is irrelevant to the polarization of the mother particle $A$ at
production. This guarantees that we can use these angular distributions to
determine the spin-parity nature of $A$ without knowing its production details.
As an example, we investigate the decay of a potential doubly-charged boson
$H^{\pm\pm}$ going to same-sign $\tau$ lepton pair.

High sensitivity quantum interferometry requires more than just access to
entangled states. It is achieved through deep understanding of quantum
correlations in a system. Integrable models offer the framework to develop this
understanding. We communicate the design of interferometric protocols for an
integrable model that describes the interaction of bosons in a four-site
configuration. Analytic formulae for the quantum dynamics of certain
observables are computed. These expose the system's functionality as both an
interferometric identifier, and producer, of NOON states. Being equivalent to a
controlled-phase gate acting on two hybrid qudits, this system also highlights
an equivalence between Heisenberg-limited interferometry and quantum
information. These results are expected to open new avenues for
integrability-enhanced atomtronic technologies.

Unavoidable variations in size and position of the building blocks of
photonic crystals cause light scattering and extinction of coherent beams. We
present a new model for both 2 and 3-dimensional photonic crystals that relates
the extinction length to the magnitude of the variations. The predicted lengths
agree well with our new experiments on high-quality opals and inverse opals,
and with literature data analyzed by us. As a result, control over photons is
limited to distances up to 50 lattice parameters ($\sim 15 \mu$m) in
state-of-the-art structures, thereby impeding large-scale applications such as
integrated circuits. Conversely, scattering in photonic crystals may lead to
novel physics such as Anderson localization and non-classical diffusion.

The paper examines a question of how much more resources do organized
business interests have when compared to resources of civil society groups in
the context of privacy lobbying in the European Union (EU). To answer to the
question, the paper draws from classical literature on power resources and
pluralism. The empirical material comes from a lobbying register maintained by
the EU. According to the results, (a) there is only a small difference in terms
of the average financial and human resources, but a vast difference when
absolute amounts are used. Furthermore, (b) organized business interests are
better affiliated with each other and other organizations. Finally, (c) many
organized business interests maintain their offices in the United States,
whereas the non-governmental organizations observed are mostly European. With
these results and the accompanying discussion, the paper contributes to the
underresearched but inflammatory topic of privacy politics.

An often used mass formula for Nambu-Goldstone (NG) bosons in QCD, such as
the pions, involves the condensate $<\overline{q}q>$, $f_{\pi}$ and the quark
current masses. We argue, within the context of the Global Colour Model to QCD,
that this expression is wrong. Analysis of the interplay between the
Dyson-Schwinger equation for the constituent quark effect and the
Bethe-Salpeter equation for the NG boson results in a new mass formula.

In this tutorial paper we summarize how the star formation (SF) history of a
galactic region can be derived from the colour-magnitude diagram (CMD) of its
resolved stars. The procedures to build synthetic CMDs and to exploit them to
derive the SF histories (SFHs) are described, as well as the corresponding
uncertainties. The SFHs of resolved dwarf galaxies of all morphological types,
obtained from the application of the synthetic CMD method, are reviewed and
discussed. In short: 1) Only early-type galaxies show evidence of long
interruptions in the SF activity; late-type dwarfs present rather continuous,
or gasping, SF regimes; 2) A few early-type dwarfs have experienced only one
episode of SF activity concentrated at the earliest epochs, whilst many others
show extended or recurrent SF activity; 3) No galaxy experiencing now its first
SF episode has been found yet; 4) No frequent evidence of strong SF bursts is
found; 5) There is no significant difference in the SFH of dwarf irregulars and
blue compact dwarfs, except for the current SF rates. Implications of these
results on the galaxy formation scenarios are briefly discussed.

On the structure of Thom polynomials of singularities

Thom polynomials of singularities express the cohomology classes dual to
singularity submanifolds. A stabilization property of Thom polynomials is known
classically, namely that trivial unfolding does not change the Thom polynomial.
In this paper we show that this is a special case of a product rule. The
product rule enables us to calculate the Thom polynomials of singularities if
we know the Thom polynomial of the product singularity. As a special case of
the product rule we define a formal power series (Thom series, Ts_Q) associated
with a commutative, complex, finite dimensional local algebra Q, such that the
Thom polynomial of {\em every} singularity with local algebra Q can be
recovered from Ts_Q.

PSI: A Pedestrian Behavior Dataset for Socially Intelligent Autonomous

Prediction of pedestrian behavior is critical for fully autonomous vehicles
to drive in busy city streets safely and efficiently. The future autonomous
cars need to fit into mixed conditions with not only technical but also social
capabilities. As more algorithms and datasets have been developed to predict
pedestrian behaviors, these efforts lack the benchmark labels and the
capability to estimate the temporal-dynamic intent changes of the pedestrians,
provide explanations of the interaction scenes, and support algorithms with
social intelligence. This paper proposes and shares another benchmark dataset
called the IUPUI-CSRC Pedestrian Situated Intent (PSI) data with two innovative
labels besides comprehensive computer vision labels. The first novel label is
the dynamic intent changes for the pedestrians to cross in front of the
ego-vehicle, achieved from 24 drivers with diverse backgrounds. The second one
is the text-based explanations of the driver reasoning process when estimating
pedestrian intents and predicting their behaviors during the interaction
period. These innovative labels can enable several computer vision tasks,
including pedestrian intent/behavior prediction, vehicle-pedestrian interaction
segmentation, and video-to-language mapping for explainable algorithms. The
released dataset can fundamentally improve the development of pedestrian
behavior prediction models and develop socially intelligent autonomous cars to
interact with pedestrians efficiently. The dataset has been evaluated with
different tasks and is released to the public to access.

Radio continuum observations offer a new window on compact objects in
globular clusters compared to typical X-ray or optical studies. As part of the
MAVERIC survey, we have used the Australia Telescope Compact Array to carry out
a deep (median central noise level of approximately 4 microJy per beam) radio
continuum survey of 26 southern globular clusters at central frequencies of 5.5
and 9.0 GHz. This paper presents a catalogue of 1285 radio continuum sources in
the fields of these 26 clusters. Considering the surface density of background
sources, we find significant evidence for a population of radio sources in
seven of the 26 clusters, and also identify at least 11 previously known
compact objects (6 pulsars and 5 X-ray binaries). While the overall density of
radio continuum sources with 7.25-GHz flux densities greater than about 20
microJy in typical globular clusters is relatively low, the survey has already
led to the discovery of several exciting compact binaries, including a
candidate ultracompact black hole X-ray binary in 47 Tuc. Many of the
unclassified radio sources near the centres of the clusters are likely to be
true cluster sources, and multi-wavelength follow-up will be necessary to
classify these objects and better understand the demographics of accreting
compact binaries in globular clusters.

We provide a fuzzball picture for Schwarzshild black holes, in which matters
and energy consisting the hole are not positioned on the central point
exclusively but oscillate around there in a serial of eigen-modes, each of
which features a special level of binding degrees and are quantum mechanically
possible to be measured outside the horizon. By listing these modes explicitly
for holes as large as $6M_\mathrm{pl}$, we find that their number increases
exponentially with the area. Basing on this picture, we present a simple but
explicitly unitary derivation of hawking radiations.

The goal of this paper is to develop some of the machinery necessary for
doing $K(2)$-local computations in the stable homotopy category using duality
resolutions at the prime $p=2$. The Morava stabilizer group $\mathbb{S}_2$
admits a norm whose kernel we denote by $\mathbb{S}_2^1$. The algebraic duality
resolution is a finite resolution of the trivial
$\mathbb{Z}_2[[\mathbb{S}_2^1]]$-module $\mathbb{Z}_2$ by modules induced from
representations of finite subgroups of $\mathbb{S}_2^1$. Its construction is
due to Goerss, Henn, Mahowald and Rezk. It is an analogue of their finite
resolution of the trivial $\mathbb{Z}_3[[\mathbb{G}_2^1]]$-module
$\mathbb{Z}_3$ at the prime $p=3$. The construction was never published and it
is the main result in this paper. In the process, we give a detailed
description of the structure of Morava stabilizer group $\mathbb{S}_2$ at the
prime $2$. We also describe the maps in the algebraic duality resolution with
the precision necessary for explicit computations.

This article extends the semidiscrete maximal $L^p$-regularity results in
[27] to multistep fully discrete finite element methods for parabolic equations
with more general diffusion coefficients in $W^{1,d+\beta}$, where $d$ is the
dimension of space and $\beta>0$. The maximal angles of $R$-boundedness are
characterized for the analytic semigroup $e^{zA_h}$ and the resolvent operator
$z(z-A_h)^{-1}$, respectively, associated to an elliptic finite element
operator $A_h$. Maximal $L^p$-regularity, optimal $\ell^p(L^q)$ error estimate,
and $\ell^p(W^{1,q})$ estimate are established for fully discrete finite
element methods with multistep backward differentiation formula.

In this paper, we examine the recent trend towards in-browser mining of
cryptocurrencies; in particular, the mining of Monero through Coinhive and
similar code- bases. In this model, a user visiting a website will download a
JavaScript code that executes client-side in her browser, mines a
cryptocurrency, typically without her consent or knowledge, and pays out the
seigniorage to the website. Websites may consciously employ this as an
alternative or to supplement advertisement revenue, may offer premium content
in exchange for mining, or may be unwittingly serving the code as a result of a
breach (in which case the seigniorage is collected by the attacker). The
cryptocurrency Monero is preferred seemingly for its unfriendliness to
large-scale ASIC mining that would drive browser-based efforts out of the
market, as well as for its purported privacy features. In this paper, we survey
this landscape, conduct some measurements to establish its prevalence and
profitability, outline an ethical framework for considering whether it should
be classified as an attack or business opportunity, and make suggestions for
the detection, mitigation and/or prevention of browser-based mining for non-
consenting users.

Do not explain without context: addressing the blind spot of model
explanations

|
The increasing number of regulations and expectations of predictive machine
learning models, such as so called right to explanation, has led to a large
number of methods promising greater interpretability. High demand has led to a
widespread adoption of XAI techniques like Shapley values, Partial Dependence
profiles or permutational variable importance. However, we still do not know
enough about their properties and how they manifest in the context in which
explanations are created by analysts, reviewed by auditors, and interpreted by
various stakeholders. This paper highlights a blind spot which, although
critical, is often overlooked when monitoring and auditing machine learning
models: the effect of the reference data on the explanation calculation. We
discuss that many model explanations depend directly or indirectly on the
choice of the referenced data distribution. We showcase examples where small
changes in the distribution lead to drastic changes in the explanations, such
as a change in trend or, alarmingly, a conclusion. Consequently, we postulate
that obtaining robust and useful explanations always requires supporting them
with a broader context.

We construct braneworld effective action in two brane Randall-Sundrum model
and show that the radion mode plays the role of a scalar field localizing
essentially nonlocal part of this action. Non-minimal curvature coupling of
this field reflects the violation of AdS/CFT-correspondence for finite values
of brane separation. Under small detuning of the brane tension from the
Randall-Sundrum flat brane value, the radion mode can play the role of
inflaton. Inflationary dynamics corresponds to branes moving apart in the field
of repelling interbrane inflaton-radion potential and implies the existence
acceleration stage caused by remnant cosmological constant at late (large brane
separation) stages of evolution. We discuss the possibility of fixing initial
conditions in this model within the concept of braneworld creation from the
tunneling or no-boundary cosmological state, which formally replaces the
conventional moduli stabilization mechanism.

We investigate temperature reservoir effects in a lossy Kerr nonlinear
resonator considering selective excitation of ooscillatory mode driven by a
sequence of Gaussian pulses. In this way, we analyze time-dependent populations
of photon-number states and quantum statistics on the base of second-order
photon correlation function in one-photon and two-photon transitions. The
effects coming from thermal reservoirs are interesting for performing more
realistic approach to generate Fock states and for study phenomena connecting
quantum engineering and temperature. We also study the role of pulse-shaping
effects during selective excitation.

Look Both Ways: Bidirectional Visual Sensing for Automatic Multi-Camera
Registration
| null | null | null | null |
cs.RO

|
This work describes the automatic registration of a large network
(approximately 40) of fixed, ceiling-mounted environment cameras spread over a
large area (approximately 800 squared meters) using a mobile calibration robot
equipped with a single upward-facing fisheye camera and a backlit ArUco marker
for easy detection. The fisheye camera is used to do visual odometry (VO), and
the ArUco marker facilitates easy detection of the calibration robot in the
environment cameras. In addition, the fisheye camera is also able to detect the
environment cameras. This two-way, bidirectional detection constrains the pose
of the environment cameras to solve an optimization problem. Such an approach
can be used to automatically register a large-scale multi-camera system used
for surveillance, automated parking, or robotic applications. This VO based
multi-camera registration method has been extensively validated using
real-world experiments, and also compared against a similar approach which uses
a LiDAR - an expensive, heavier and power hungry sensor.

density of a spot on x-ray film is estimated from macroscopic digital images.
The spot's size is used to compensate for the lack of dynamic range obtainable
with digital imaging hardware. These densities are compared to manually

Although there has been substantial research in software analytics for effort
estimation in traditional software projects, little work has been done for
estimation in agile projects, especially estimating user stories or issues.
Story points are the most common unit of measure used for estimating the effort
involved in implementing a user story or resolving an issue. In this paper, we
offer for the \emph{first} time a comprehensive dataset for story points-based
estimation that contains 23,313 issues from 16 open source projects. We also
propose a prediction model for estimating story points based on a novel
combination of two powerful deep learning architectures: long short-term memory
and recurrent highway network. Our prediction system is \emph{end-to-end}
trainable from raw input data to prediction outcomes without any manual feature
engineering. An empirical evaluation demonstrates that our approach
consistently outperforms three common effort estimation baselines and two
alternatives in both Mean Absolute Error and the Standardized Accuracy.

STT: Soft Template Tuning for Few-Shot Adaptation
| null | null | null | null |
cs.CL cs.AI
|
http://arxiv.org/licenses/nonexclusive-distrib/1.0/
|
Prompt tuning has been an extremely effective tool to adapt a pre-trained
model to downstream tasks. However, standard prompt-based methods mainly
consider the case of sufficient data of downstream tasks. It is still unclear
whether the advantage can be transferred to the few-shot regime, where only
limited data are available for each downstream task. Although some works have
demonstrated the potential of prompt-tuning under the few-shot setting, the
main stream methods via searching discrete prompts or tuning soft prompts with
limited data are still very challenging. Through extensive empirical studies,
we find that there is still a gap between prompt tuning and fully fine-tuning
for few-shot learning. To bridge the gap, we propose a new prompt-tuning
framework, called Soft Template Tuning (STT). STT combines manual and auto
prompts, and treats downstream classification tasks as a masked language
modeling task. Comprehensive evaluation on different settings suggests STT can
close the gap between fine-tuning and prompt-based methods without introducing
additional parameters. Significantly, it can even outperform the time- and
resource-consuming fine-tuning method on sentiment classification tasks.

As a promising area in artificial intelligence, a new learning paradigm,
called Small Sample Learning (SSL), has been attracting prominent research
attention in the recent years. In this paper, we aim to present a survey to
comprehensively introduce the current techniques proposed on this topic.
Specifically, current SSL techniques can be mainly divided into two categories.
The first category of SSL approaches can be called "concept learning", which
emphasizes learning new concepts from only few related observations. The
purpose is mainly to simulate human learning behaviors like recognition,
generation, imagination, synthesis and analysis. The second category is called
"experience learning", which usually co-exists with the large sample learning
manner of conventional machine learning. This category mainly focuses on
learning with insufficient samples, and can also be called small data learning
in some literatures. More extensive surveys on both categories of SSL
techniques are introduced and some neuroscience evidences are provided to
clarify the rationality of the entire SSL regime, and the relationship with
human learning process. Some discussions on the main challenges and possible
future research directions along this line are also presented.

We show that a class of fermion theory formulated on a compact, curved
manifold will generate a condensate whose magnitude is determined only by the
volume and Euler characteristic of the space. The construction requires that
the fermions be treated as K\"{a}hler-Dirac fields and the condensate arises
from an anomaly associated with a $U(1)$ global symmetry which is subsequently
broken to a discrete subgroup. Remarkably the anomaly survives under
discretization of the space which allows us to compute the condensate on an
arbitrary triangulation. The results, being topological in character, should
hold in a wide range of gravitationally coupled fermion theories both classical
and quantum

If a pure state of a qubit pair is developed over the four basis states, it
is known that an equality between the four coefficients of that development
exists if and only if that state is unentangled. This paper considers an
arbitrary pure state of an N-qubit system, developed over the 2^N basis states.
It is shown that the state is unentangled if and only if a well-chosen
collection of (2^N-(N+1)) equalities between the 2^N coefficients of that
development is verified. The number of these equalities is large a soon as N =
10, but it is shown that this set of equalities may be classified into (N-1)
subsets, which should facilitate their manipulation. This result should be
useful e.g. in the contexts of Blind Quantum Source Separation (BQSS) and Blind
Quantum Process Tomography (BQPT), with an aim which should not be confused
with that found when using the concept of equivalence of pure states through
local unitary transformations.

We report on a first-principles study of the conductance through graphene
suspended between Al contacts as a function of junction length, width, and
orientation. The charge transfer at the leads and into the freestanding section
gives rise to an electron-hole asymmetry in the conductance and in sufficiently
long junctions induces two conductance minima at the energies of the Dirac
points for suspended and clamped regions, respectively. We obtain the potential
profile along a junction caused by doping and provide parameters for effective
model calculations of the junction conductance with weakly interacting metallic
leads.

Learning from past scans: Tomographic reconstruction to detect new

The need for tomographic reconstruction from sparse measurements arises when
the measurement process is potentially harmful, needs to be rapid, or is
uneconomical. In such cases, prior information from previous longitudinal scans
of the same or similar objects helps to reconstruct the current object whilst
requiring significantly fewer `updating' measurements. However, a significant
limitation of all prior-based methods is the possible dominance of the prior
over the reconstruction of new localised information that has evolved within
the test object. In this paper, we improve the state of the art by (1)
detecting potential regions where new changes may have occurred, and (2)
effectively reconstructing both the old and new structures by computing
regional weights that moderate the local influence of the priors. We have
tested the efficacy of our method on synthetic as well as real volume data. The
results demonstrate that using weighted priors significantly improves the
overall quality of the reconstructed data whilst minimising their impact on
regions that contain new information.

Many successful applications of computer vision to image or video
manipulation are interactive by nature. However, parameters of such systems are
often trained neglecting the user. Traditionally, interactive systems have been
treated in the same manner as their fully automatic counterparts. Their
performance is evaluated by computing the accuracy of their solutions under
some fixed set of user interactions. This paper proposes a new evaluation and
learning method which brings the user in the loop. It is based on the use of an
active robot user - a simulated model of a human user. We show how this
approach can be used to evaluate and learn parameters of state-of-the-art
interactive segmentation systems. We also show how simulated user models can be
integrated into the popular max-margin method for parameter learning and
propose an algorithm to solve the resulting optimisation problem.

The behavior of flux lines in the presence of both columnar and point
disorder in 1+1 dimension is investigated using Renormalization Group and
world-line Quantum Monte Carlo techniques. In particular, we calculate the
transverse wandering correlation function for a single boson and recover known
results for point and columnar disorder separately. We then examine the
existence of a localization transition of a flux line in the simultaneous
presence of both types of disorder. We also perform RG for interacting flux
lines in the presence of both disorder. RG indicates that the vortex glass is
unstable with respect to arbitrary small amount of columnar disorder. Using QMC
we find that the Bose glass transition temperature is reduced by the point
disorder, in agreement with recent RG calculations. Further we find that the
region posited to be an Anderson glass is completely destroyed.

A map merging component is crucial for the proper functionality of a
multi-robot system performing exploration, since it provides the means to
integrate and distribute the most important information carried by the agents:
the explored-covered space and its exact (depending on the SLAM accuracy)
morphology. Map merging is a prerequisite for an intelligent multi-robot team
aiming to deploy a smart exploration technique. In the current work, a metric
map merging approach based on environmental information is proposed, in
conjunction with spatially scattered RFID tags localization. This approach is
divided into the following parts: the maps approximate rotation calculation via
the obstacles poses and localized RFID tags, the translation employing the best
localized common RFID tag and finally the transformation refinement using an
ICP algorithm.

Magnetic susceptibility $\chi$ of pristine and brominated arc-produced sample
of multiwall carbon nanotubes was measured from 4.2 to 400 K. An additional
contribution $\Delta \chi(T)$ to diamagnetic susceptibility $\chi(T)$ of carbon
nanotubes was found at T $<$ 50 K for both samples. It is shown that $\Delta
\chi(T)$ are dominated by quantum correction to $\chi$ for interaction
electrons (interaction effects-IE). The IE shows a crossover from
two-dimensional to three-dimensional at $B$ = 5.5 T. The effective interaction
between electrons for interior layers of nanotubes are repulsion and the
electron-electron interaction $\lambda$$_c$ was estimated to be $\lambda_c\sim
$ 0.26.

In this article, we introduce a new family of sense preserving harmonic
mappings f in the open unit disk and prove that functions in this family are
close-to-convex. We give some basic properties such as coefficient bounds,
growth estimates, convolution and determine the radius of convexity for the
functions belonging to this family. In addition, we construct certain harmonic
univalent polynomials belonging to this family.

The evaporation of sessile drops in quiescent air is usually governed by
vapour diffusion. For contact angles below $90^\circ$, the evaporative flux
from the droplet tends to diverge in the vicinity of the contact line.
Therefore, the description of the flow inside an evaporating drop has remained
a challenge. Here, we focus on the asymptotic behaviour near the pinned contact
line, by analytically solving the Stokes equations in a wedge geometry of
arbitrary contact angle. The flow field is described by similarity solutions,
with exponents that match the singular boundary condition due to evaporation.
We demonstrate that there are three contributions to the flow in a wedge: the
evaporative flux, the downward motion of the liquid-air interface and the
eigenmode solution which fulfils the homogeneous boundary conditions. Below a
critical contact angle of $133.4^\circ$, the evaporative flux solution will
dominate, while above this angle the eigenmode solution dominates. We
demonstrate that for small contact angles, the velocity field is very
accurately described by the lubrication approximation. For larger contact
angles, the flow separates into regions where the flow is reversing towards the
drop centre.

In this note, we derive a Liouville theorem for the complex Monge-Amp\`ere
equation. Our result states that if the global solution $u$ of the complex
Monge-Amp\`ere equation with constant right-hand side differs from a quadratic
polynomial solution by $o(\abs{x}^2)$ at infinity, then $u$ is a quadratic
polynomial.

Electron Ion Collider (EIC) is a particle accelerator facility planned for
construction at Brookhaven National Laboratory on Long Island, New York by the
United States Department of Energy. EIC will provide capabilities of colliding
beams of polarized electrons with polarized beams of proton and light ions. EIC
will be one of the largest and most sophisticated new accelerator facilities
worldwide, and the only new large-scale accelerator facility planned for
construction in the United States in the next few decades. The versatility,
resolving power and intensity of EIC will present many new opportunities to
address some of the crucial and fundamental open scientific questions in
particle physics. This document provides an overview of the science case of EIC
from the perspective of the high energy physics community.

For a complex connected reductive group G, we classify the simple modules
whose cone of primitive vectors admits a nontrivial G-invariant deformation. We
relate this classification to that of simple Jordan algebras, and to that (due
to Akhiezer) of smooth projective varieties whose orbits under the action of a
connected affine algebraic group are a divisor and its complementary. Our main
tool is the invariant Hilbert scheme of Alexeev-Brion; we determine the first
examples of it. We also determine the infinitesimal deformations (non
necessarily G-invariant) of the cones of primitive vectors; they turn out to be
trivial for most simple modules.

Time-dependent quantum transport for graphene nanoribbons (GNR) are
calculated by the hierarchical equation of motion (HEOM) method based on the
nonequilibrium Green's function (NEGF) theory (Xie et.al, J. Chem. Phys. 137,
044113, 2012). In this paper, a new steady state calculation technique is
introduced and accelerated by the contour integration, which is suitable for
large systems. Three Lorentzian fitting schemes for the self-energy matrices
are developed based on the nonlinear least square method. Within these schemes,
the number of Lorentzians is effectively reduced and the fitting results are
good and convergent. With these two developments in HEOM, we have calculated
the transient currents in GNR. We find a new type of edge state with
delta-function-like density of states in many semi-infinite armchair-type GNR.

In semi-supervised learning for classification, it is assumed that every
ground truth class of data is present in the small labelled dataset. Many
real-world sparsely-labelled datasets are plausibly not of this type. It could
easily be the case that some classes of data are found only in the unlabelled
dataset -- perhaps the labelling process was biased -- so we do not have any
labelled examples to train on for some classes. We call this learning regime
$\textit{semi-unsupervised learning}$, an extreme case of semi-supervised
learning, where some classes have no labelled exemplars in the training set.
First, we outline the pitfalls associated with trying to apply deep generative
model (DGM)-based semi-supervised learning algorithms to datasets of this type.
We then show how a combination of clustering and semi-supervised learning,
using DGMs, can be brought to bear on this problem. We study several different
datasets, showing how one can still learn effectively when half of the ground
truth classes are entirely unlabelled and the other half are sparsely labelled.

Ab-initio density functional theory (DFT) calculations of the relative
stability of anatase and rutile polymorphs of TiO2 were carried using
all-electron atomic orbitals methods with local density approximation (LDA).
The rutile phase exhibited a moderate margin of stability of ~ 3 meV relative
to the anatase phase in pristine material. From computational analysis of the
formation energies of Si, Al, Fe and F dopants of various charge states across
different Fermi level energies in anatase and in rutile, it was found that the
cationic dopants are most stable in Ti substitutional lattice positions while
formation energy is minimised for F- doping in interstitial positions. All
dopants were found to considerably stabilise anatase relative to the rutile
phase, suggesting the anatase to rutile phase transformation is inhibited in
such systems with the dopants ranked F>Si>Fe>Al in order of anatase
stabilisation strength. Al and Fe dopants were found to act as shallow
acceptors with charge compensation achieved through the formation of mobile
carriers rather than the formation of anion vacancies.

We investigate statistically the dynamical consequences of cosmological
fluxes of matter and related moments on progenitors of today's dark matter
haloes. Their dynamics is described via canonical perturbation theory which
accounts for two types of perturbations: the tidal field corresponding to
fly-bys and accretion of dark matter through the halo's outer boundary. he
dynamical equations are solved linearly, order by order, projecting on a
biorthogonal basis to consistently satisfy the field equation. Since our
solution of the Boltzmann Poisson equations is explicit, it allows statistical
predictions for the ensemble distribution of the inner dynamical features of
haloes. The secular evolution of open galactic haloes is investigated: we
derive the kinetic equation which governs the quasi-linear evolution of dark
matter profile induced by infall and its corresponding gravitational
correlations. This yields a Fokker Planck-like equation for the angle-averaged
underlying distribution function. We show how these extensions to the classical
theory could be used to (i) observationally constrain the statistical nature of
the infall (ii) predict the observed distribution and correlations of
substructures in upcoming surveys, (iii) predict the past evolution of the
observed distribution of clumps, and finally (iv) weight the relative
importance of the intrinsic (via the unperturbed distribution function) and
external (tidal and/ or infall) influence of the environment in determining the
fate of galaxies.

Analyzing the neutrino Yukawa effect in the freeze-out process of a generic
dark matter candidate with right-handed neutrino portal, we identify the
parameter regions satisfying the observed dark matter relic density as well as
the current Fermi-LAT and H.E.S.S. limits and the future CTA reach on gamma-ray
signals. In this scenario the dark matter couples to the Higgs boson at
one-loop level and thus could be detected by spin-independent nucleonic
scattering for a reasonable range of the relevant parameters.

Coherent quantum optics, where the interaction of a photon with an emitter
does not scramble phase coherence, lies at the heart of many quantum optical
effects and emerging technologies. Solid-state emitters coupled to nanophotonic
waveguides are a promising platform for quantum devices, as this combination is
scalable. Yet, reaching full coherence in these systems is challenging due to
the dynamics of the solid-state environment of the emitters. Here, we review
progress towards coherent light-matter interactions with solid-state quantum
emitters coupled to nanophotonic waveguides. We first lay down the theoretical
foundation for coherent and nonlinear light-matter interactions of a two-level
system in a quasi-one-dimensional system, and then benchmark experimental
realizations. We then discuss higher-order nonlinearities that arise due to the
addition of photons of different frequencies, more complex energy-level schemes
of the emitters, and the coupling of multiple emitters via a shared photonic
mode. Throughout, we highlight protocols for applications and novel effects
that are based on these coherent interactions, the steps taken towards their
realization, and the challenges that remain to be overcome.

The field of descriptive combinatorics investigates the question, to what
extent can classical combinatorial results and techniques be made topologically
or measure-theoretically well-behaved? This paper examines a class of coloring
problems induced by actions of countable groups on Polish spaces, with the
requirement that the desired coloring be Baire measurable. We show that the set
of all such coloring problems that admit a Baire measurable solution for a
particular free action $\alpha$ is complete analytic (apart from the trivial
situation when the orbit equivalence relation induced by $\alpha$ is smooth on
a comeager set); this result confirms the "hardness" of finding a topologically
well-behaved coloring. When $\alpha$ is the shift action, we characterize the
class of problems for which $\alpha$ has a Baire measurable coloring in purely
combinatorial terms; it turns out that closely related concepts have already
been studied in graph theory with no relation to descriptive set theory. We
remark that our framework permits a wholly dynamical interpretation (with
colorings corresponding to equivariant maps to a given subshift), so this
article can also be viewed as a contribution to generic dynamics.

In this paper, we report on the development progress of correlation-based
optical time domain reflectometry (OTDR). Substituting the direct detection
receiver with a coherent receiver enables to extract the phase and polarization
information of the reflected signal. Furthermore, due to the mixing of a weak
probe signal with a strong local oscillator the sensitivity of the receiver
improved. This improvement was demonstrated by analyzing the reflection from an
angled physical contact (APC) connector. To further quantify the improvements,
we compare the direct detection correlation OTDR (C-OTDR) with the coherent
detection correlation OTDR (CC-OTDR) with respect to the spatial and amplitude
resolution.

Remarks about Synthetic Upper Ricci Bounds for Metric Measure Spaces

We discuss various characterizations of synthetic upper Ricci bounds for
metric measure spaces in terms of heat flow, entropy and optimal transport. In
particular, we present a characterization in terms of semiconcavity of the
entropy along certain Wasserstein geodesics which is stable under convergence
of mm-spaces. And we prove that a related characterization is equivalent to an
asymptotic lower bound on the growth of the Wasseretein distance between heat
flows. For weighted Riemannian manifolds, the crucial result will be a precise
uniform two-sided bound for \begin{eqnarray*}\frac{d}{dt}\Big|_{t=0}W\big(\hat
P_t\delta_x,\hat P_t\delta_y\big)\end{eqnarray*} in terms of the mean value of
the Bakry-Emery Ricci tensor $\mathrm{Ric}+\mathrm{Hess}\, f$ along the
minimizing geodesic from $x$ to $y$ and an explicit correction term depending
on the bound for the curvature along this curve.

Spark provides an in-memory implementation of MapReduce that is widely used
in the big data industry. MPI/OpenMP is a popular framework for high
performance parallel computing. This paper presents a high performance
MapReduce design in MPI/OpenMP and uses that to compare with Spark on the
classic word count MapReduce task. My result shows that the MPI/OpenMP
MapReduce outperforms Apache Spark by about 300%.
