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 ...

Moving in the Dark: Enlightening the Spatial Population Ecology of European Cave Salamanders
Population Ecology, EarlyView.We assessed individual interactions, movement ecology and activity patterns of a subterranean population of Speleomantes strinatii, applying spatial capture–recapture modeling to a photographic dataset of 104 individuals. ABSTRACT Space use and movement are fundamental aspects of organisms' ecology, mirroring individual fitness, behavior, and life ...

A phenomenological analysis of LHC neutrino scattering at NLO accuracy matched to parton showers
European Physical Journal C: Particles and FieldsWe perform a detailed phenomenological study of high-energy neutrino deep inelastic scattering (DIS) focused on LHC far-forward experiments such as FASER $$\nu $$ ν and SND@LHC.

Theory of monomial groups [PDF]
Transactions of the American Mathematical Society, 1942 The process of imbedding a group in a larger group of some prescribed type has been one of the most useful tools in the investigation of properties of groups. The three principal types of representation of groups, each with its particular field of usefulness, are the following: 1. Permutation groups. 2. Monomial groups. 3.

Population Ecology, EarlyView.Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size

A theory of group selection. [PDF]
Proceedings of the National Academy of Sciences, 1975 In organisms possessing a dispersal phase the processes of mating, competition, feeding, and predation are often carried out within "trait-groups," defined as populations enclosed in areas smaller than the boundaries of the deme. A simple model shows that this can lead to the selection of "altruistic" traits that favor the fitness of the group over ...

Evolutionary interplay between viruses and R‐loops
FEBS Letters, EarlyView.Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

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 ...

Bootstrapping line defects in N $$ \mathcal{N} $$ = 2 theories
Journal of High Energy Physics, 2020 We study half-BPS line defects in N $$ \mathcal{N} $$ = 2 superconformal theories using the bootstrap approach. We concentrate on local excitations constrained to the defect, which means the system is a 1d defect CFT with osp(4∗ |2) symmetry. In order to

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.
