Query: Effects of Publications in Proceedings on the Measure of the Core Size
  of Coauthors   Coauthors (CA) of a "lead investigator" (LI) can receive a rank (r) according
to their "importance" in having published joint publications with the LI. It is
commonly accepted, without any proof, that publications in peer review journals
and e.g. conference proceedings do not have the same "value" in a CV. Same for
papers contributed to encyclopedia and book chapters. It is here examined
whether the relationship between the number (J) of publications of some
scientist with her/his coauthors, ranked according to their decreasing
importance, i.e. $ J \propto 1/r^{\alpha} $, as found by Ausloos, still holds
if the overall publication list is broken into such specific types of
publications. Several authors, with different careers, but mainly having worked
in the field of statistical mechanics, are studied here to sort out answers to
the questions. The exponent $\alpha$ turns out to be weakly scientist
dependent, only if the maximum value of J and r is large and is $\sim +1$ then.
The $m_A$ core value, i.e. the core number of CAs, for proceedings only is
about half of the total one, i.e. when all publications are counted.
Contributions to the numerical values from both encyclopedia and book chapters
are marginal. The role of a time span on $m_A$ is also examined in two cases in
relation to career activity considerations. It can considered that the findings
serve as a contrasting point of view on how to quantify an individual
(publication) career as recently done by Petersen et al., here emphasizing the
collaboration size and evolution, rather than a citation count, moreover
specifying the type of publication. Through the various $m_A$'s one can
distinguish different behavior patterns of a scientist publication with CAs.
