Simple representations of BPS algebras: the case of $$Y(\widehat{\mathfrak {gl}}_2)$$ Y ( gl ^ 2 )
European Physical Journal C: Particles and FieldsBPS algebras are the symmetries of a wide class of brane-inspired models. They are closely related to Yangians – the peculiar and somewhat sophisticated limit of DIM algebras. Still they possess some simple and explicit representations.

Noncommutative symmetric functions with matrix parameters [PDF]
Discrete Mathematics & Theoretical Computer Science, 2012 We define new families of noncommutative symmetric functions and quasi-symmetric functions depending on two matrices of parameters, and more generally on parameters associated with paths in a binary tree. Appropriate specializations of both matrices then

Regional Differences in High Elevation Snowpack Decline Along the North American Rocky Mountains
Hydrological Processes, Volume 39, Issue 5, May 2025.Historical trends from 1991 through 2020 were analysed from high elevation snow stations along a 2500 km corridor of the North American Rocky Mountains. This revealed declining maximum and April 1 snowpacks, and earlier snowpack peaks. A latitudinal pattern was observed, with slight changes in northern regions (blue) and increasing decline rates ...

Macdonald’s polynomials and representations of quantum groups [PDF]
Mathematical Research Letters, 1994 In this paper we present a formula for Macdonald's polynomials for the root system A(n-1) which arises from the representation theory of quantum sl(n). This formula expresses Macdonald's polynomials via (weighted) traces of intertwining operators between certain modules over quantum sl(n).

A follow‐up assessment of wildlife‐permeable fences used in the reintroduction of bison
Wildlife Biology, Volume 2025, Issue 3, May 2025.Fences are an important tool for anchoring reintroduced species to a target area, and there is a need to understand their effect on other wildlife species. However, little is understood about the response of wildlife to newly constructed fences over time. We evaluated fences used in the reintroduction of plains bison Bison bison to Banff National Park,

LAST BUT NOT LEAST: LAGGARD FIRMS, TECHNOLOGY DIFFUSION, AND ITS STRUCTURAL AND POLICY DETERMINANTS
International Economic Review, Volume 66, Issue 2, Page 595-627, May 2025.Abstract Using a unique microaggregated data set on firm‐level productivity in 13 countries from 1995 to 2014, this article provides new evidence on technology‐ and knowledge‐diffusion barriers for laggard firms. We show that, although the least productive firms benefit from a catch‐up effect, their speed of catchup is lower in digital‐ and skill ...

Inversion of the Pieri formula for Macdonald polynomials
Advances in Mathematics, 2006 We give the explicit analytic development of Macdonald polynomials in terms of "modified complete" and elementary symmetric functions. These expansions are obtained by inverting the Pieri formula. Specialization yields similar developments for monomial, Jack and Hall-Littlewood symmetric functions.

Human Brain Mapping, Volume 46, Issue 6, April 15, 2025.This research reveals that older adults demonstrate steadier attentional engagement and earlier evidence accumulation, favouring a more exploitative task approach. In contrast, younger adults exhibit more frequent mind‐wandering and perceptual decoupling, flexibly shifting between exploration and exploitation without compromising overall task ...

Identifying Reliable Change in Outcome Assessments for Behavioral Interventions
Behavioral Interventions, Volume 40, Issue 2, April 2025.ABSTRACT Behavioral interventions have demonstrated group‐level benefits for a variety of behavioral presentations and conditions. The ability to capture and quantify reliable individual‐level change during the course of behavioral interventions is essential for making rational clinical management decisions.
