@article{6855, abstract = {Many traits of interest are highly heritable and genetically complex, meaning that much of the variation they exhibit arises from differences at numerous loci in the genome. Complex traits and their evolution have been studied for more than a century, but only in the last decade have genome-wide association studies (GWASs) in humans begun to reveal their genetic basis. Here, we bring these threads of research together to ask how findings from GWASs can further our understanding of the processes that give rise to heritable variation in complex traits and of the genetic basis of complex trait evolution in response to changing selection pressures (i.e., of polygenic adaptation). Conversely, we ask how evolutionary thinking helps us to interpret findings from GWASs and informs related efforts of practical importance.}, author = {Sella, Guy and Barton, Nicholas H}, issn = {1545-293X}, journal = {Annual Review of Genomics and Human Genetics}, pages = {461--493}, publisher = {Annual Reviews}, title = {{Thinking about the evolution of complex traits in the era of genome-wide association studies}}, doi = {10.1146/annurev-genom-083115-022316}, volume = {20}, year = {2019}, } @article{6840, abstract = {We discuss thermodynamic properties of harmonically trapped imperfect quantum gases. The spatial inhomogeneity of these systems imposes a redefinition of the mean-field interparticle potential energy as compared to the homogeneous case. In our approach, it takes the form a 2N2 ωd, where N is the number of particles, ω—the harmonic trap frequency, d—system’s dimensionality, and a is a parameter characterizing the interparticle interaction. We provide arguments that this model corresponds to the limiting case of a long-ranged interparticle potential of vanishingly small amplitude. This conclusion is drawn from a computation similar to the well-known Kac scaling procedure, which is presented here in a form adapted to the case of an isotropic harmonic trap. We show that within the model, the imperfect gas of trapped repulsive bosons undergoes the Bose–Einstein condensation provided d > 1. The main result of our analysis is that in d = 1 the gas of attractive imperfect fermions with a = −aF < 0 is thermodynamically equivalent to the gas of repulsive bosons with a = aB > 0 provided the parameters aF and aB fulfill the relation aB + aF = . This result supplements similar recent conclusion about thermodynamic equivalence of two-dimensional (2D) uniform imperfect repulsive Bose and attractive Fermi gases.}, author = {Mysliwy, Krzysztof and Napiórkowski, Marek}, issn = {1742-5468}, journal = {Journal of Statistical Mechanics: Theory and Experiment}, number = {6}, publisher = {IOP Publishing}, title = {{Thermodynamics of inhomogeneous imperfect quantum gases in harmonic traps}}, doi = {10.1088/1742-5468/ab190d}, volume = {2019}, year = {2019}, } @article{6843, abstract = {The aim of this short paper is to offer a complete characterization of all (not necessarily surjective) isometric embeddings of the Wasserstein space Wp(X), where S is a countable discrete metric space and 0
