Infinite flags and Schubert polynomials
We study Schubert polynomials using geometry of infinite-dimensional flag varieties and degeneracy loci. Applications include Graham-positivity of coefficients appearing in equivariant coproduct formulas and expansions of back-stable and enriched ...

Adolescents' trajectories of mental health in the MYRIAD trial
Abstract Background This study explored adolescent's mental health trajectories over the course of a school‐based mindfulness‐based intervention trial (MYRIAD). It examined whether intervention condition (mindfulness vs. teaching‐as‐usual), individual‐level and contextual‐level factors were associated with different trajectories.

ABSTRACT With climate change, birds will face increasing thermoregulatory demands, which may alter reproductive behaviors such as offspring provisioning. Experimental studies have shown that the provisioning capacity of female tree swallows (Tachycineta bicolor) is limited by their risk of overheating. Given that parental investment strategies may vary

Combinatorial 𝐵_{𝑛}-analogues of Schubert polynomials [PDF]
Combinatorial B n B_{n} -analogues of Schubert polynomials and corresponding symmetric functions are constructed and studied. The development is based on an exponential solution of the type B B Yang-Baxter equation that involves the nilCoxeter algebra of the hyperoctahedral group.

A Dynamical Model for the Shallow‐to‐Deep Transition of Amazonian Moist Atmospheric Convection
Abstract The development of deep convection and the timing of storm convection initiation over land are generally poorly represented by weather and climate models, probably due to the poor representation of the interaction between shallow and deep convection.

Abstract Column‐integrated moist static energy (MSE) budgets underpin theories of tropical convection and circulation, yet in reanalyses and climate models the budget rarely closes; residuals routinely match the leading terms and mask physical insights.

Billey's formula in combinatorics, geometry, and topology [PDF]
In this expository paper we describe a powerful combinatorial formula and its implications in geometry, topology, and algebra. This formula first appeared in the appendix of a book by Andersen, Jantzen, and Soergel.

Abstract Arctic lake, bay and lagoon ice regimes play a crucial role in understanding permafrost stability, hydrology, and carbon cycling in permafrost regions. This study integrates field and Synthetic Aperture Radar (SAR) data from Sentinel‐1 to improve the classification of Arctic lake, bay and lagoon ice regimes, with a particular focus on the ...

Universal Schubert polynomials
We introduce polynomials that represent general degeneracy loci for maps of vector bundles. These polynomials specialize to the known classical and quantum forms of single and double Schubert polynomials. This is the final version of the paper, to appear in Duke Math. J.

Climate Change Challenges Grey Wolf Resilience: Insights From Dental Microwear
We investigate dietary plasticity in European grey wolves across interglacial periods using dental microwear texture analysis. Enhanced durophagy is associated with warm climates in both modern Polish and British Pleistocene wolves, indicating deep‐time behavioural flexibility.
