DNA-Based Kinship Analysis
Relatedness between individuals and groups can be investigated using DNA markers. A child’s DNA profile is a combination of alleles passed down from the father and mother. This means that relationships can be investigated between alleged family members. DNA profiling is commonly used to test for potential paternity, parentage and sibship (whether people are related as brothers or sisters) relationships. In many forensic cases more complex relationships have to be considered
Space Assurance or Space Dominance? The Case Against Weaponizing Space
Argues that the pursuit of space dominance could impair global commerce, produce long-lasting, environmental debris in space, and harm alliance ties as well as relations between the United States and Russia and China
Centrality and pseudorapidity dependence of the transverse energy flow in pPb collisions at sqrt(s_NN) = 5.02 TeV
The almost hermetic coverage of CMS is used to measure the distribution of
transverse energy as a function of pseudo-rapidity for pPb collisions at
TeV. For minimum bias collisions
reaches 23 GeV which implies an per participant pair comparable to that
of peripheral PbPb collisions at TeV. The centrality
dependence of transverse energy production has been studied using centrality
measures defined in three different angular regions. There is a strong
auto-correlation between and the range used to define
centrality %both for data and the EPOS-LHC and HIJING event generators. The
centrality dependence of the data is much stronger for values on the
lead side than the proton side and shows significant differences from that
predicted by either event generator.Comment: 4 pages, 4 figures, proceedings of the Quark Matter 2015 Conferenc
From Polygons to Ultradiscrete Painlev\'e Equations
The rays of tropical genus one curves are constrained in a way that defines a
bounded polygon. When we relax this constraint, the resulting curves do not
close, giving rise to a system of spiraling polygons. The piecewise linear
transformations that preserve the forms of those rays form tropical rational
presentations of groups of affine Weyl type. We present a selection of
spiraling polygons with three to eleven sides whose groups of piecewise linear
transformations coincide with the B\"acklund transformations and the evolution
equations for the ultradiscrete Painlev\'e equations
Thermal Corrections to R\'enyi entropies for Free Fermions
We calculate thermal corrections to R\'{e}nyi entropies for free massless
fermions on a sphere. More specifically, we take a free fermion on
and calculate the leading thermal correction
to the R\'{e}nyi entropies for a cap like region with opening angle .
By expanding the density matrix in a Boltzmann sum, the problem of finding the
R\'{e}nyi entropies can be mapped to the problem of calculating a two point
function on an sheeted cover of the sphere. We follow previous work for
conformal field theories to map the problem on the sphere to a conical region
in Euclidean space. By using the method of images, we calculate the two point
function and recover the R\'{e}nyi entropies.Comment: 15 pages, 5 figure
