Denning Phenology Mediates Sea‐Ice Loss Impacts on Early Reproductive Success in Polar Bears

open access: yesGlobal Change Biology, Volume 32, Issue 8, August 2026.
Changes in overwinter sheltering phenology in response to climate change and their fitness consequences have rarely been studied. Here, we show that climate change has disrupted the phenology of overwinter maternity denning in polar bears, with females emerging from den earlier when sea‐ice had been scarce the preceding year.

Exercise Dependence and Cardiovascular Reactivity to Acute Psychological Stress: An Extension and Replication Study

open access: yesPsychophysiology, Volume 63, Issue 8, August 2026.
ABSTRACT Low cardiovascular reactions to acute psychological stress have been shown among those with substance and non‐substance dependencies like exercise dependence. However, associations between exercise dependence and low cardiovascular reactions to stress have been demonstrated between small sex‐specific groups with extreme exercise dependence ...

When is the graph of a random 0/1 polytope a clique?

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 8, August 2026.
Abstract We study graph‐theoretic properties of random 0/1$0/1$ polytopes. Specifically, let Qpn⊆{0,1}n$Q_p^n \subseteq \lbrace 0,1\rbrace ^n$ be a random subset where each point is included independently with probability p$p$, and consider the graph Gp$G_p$ of the polytope conv(Qpn)$\operatorname{conv}(Q_p^n)$.

Convergence of Hermite expansions in modulation spaces

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 8, August 2026.
Abstract The aim of this paper is to give an elementary proof that the Hermite expansion of a function f$f$ in the modulation space Mp(R)$M^p({\mathbb {R}})$ converges to f$f$ in Mp(R)$M^p({\mathbb {R}})$ when 1

Lower bounds for cube‐ideal set‐systems

open access: yesProceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.
Abstract A set‐system S⊆{0,1}n$S\subseteq \lbrace 0,1\rbrace ^n$ is cube‐ideal if its convex hull can be described by capacity and generalized set covering inequalities. In this paper, we use combinatorics, convex geometry, and polyhedral theory to give exponential lower bounds on the size of cube‐ideal set‐systems, and linear lower bounds on their ...
