Network topology drives population temporal variability in experimental habitat networks
Population Ecology, EarlyView.Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Source terms for electroweak baryogenesis in the vev-insertion approximation beyond leading order
Journal of High Energy Physics, 2020 In electroweak baryogenesis the baryon asymmetry of the universe is created during the electroweak phase transition. The quantum transport equations governing the dynamics of the plasma particles can be derived in the vev-insertion approximation, which ...

Sparse SYK and traversable wormholes
Journal of High Energy Physics, 2021 We investigate two sparse Sachdev-Ye-Kitaev (SYK) systems coupled by a bilinear term as a holographic quantum mechanical description of an eternal traversable wormhole in the low temperature limit.

Bosonic Colored Group Field Theory
, 2009 Bosonic colored group field theory is considered. Focusing first on dimension four, namely the colored Ooguri group field model, the main properties of Feynman graphs are studied.

School Science and Mathematics, 1918 In this chapter we state (mostly without proof) some basic facts from the theory of groups. We have included only those facts from the general theory that we shall have occasion to use later — the treatment is by no means exhaustive. We refer to any standard textbook on Group Theory for more detailed accounts of the subject in general and for the ...

The theory of dual groups [PDF]
Fundamenta Mathematicae, 1994 This paper studies the \(L_{\infty\omega}\)-theory of sequences of dual groups. Here, a dual group is an Abelian group of the form \(B^*=\Hom(B, \mathbb{Z})\), where \(\mathbb{Z}\) denotes the group of integers. The short sequence associated to a dual group \(A_ 0\) is defined to be the 4-sorted structure \((A_ 0, A_ 1, A_ 2, \mathbb{Z}; \sigma_ 0 ...

Geographic variation in walking activity in the red flour beetle Tribolium castaneum
Population Ecology, EarlyView.This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.

Resummation improved rapidity spectrum for gluon fusion Higgs production
Journal of High Energy Physics, 2017 Gluon-induced processes such as Higgs production typically exhibit large perturbative corrections. These partially arise from large virtual corrections to the gluon form factor, which at timelike momentum transfer contains Sudakov logarithms evaluated at
