Demazure crystals and the energy function [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2011
There is a close connection between Demazure crystals and tensor products of Kirillov–Reshetikhin crystals. For example, certain Demazure crystals are isomorphic as classical crystals to tensor products of Kirillov–Reshetikhin crystals via a canonically ...

A product formula for certain Littlewood-Richardson coefficients for Jack and Macdonald polynomials [PDF]

open access: yes, 2014
Jack polynomials generalize several classical families of symmetric polynomials, including Schur polynomials, and are further generalized by Macdonald polynomials.

Differences in Performance in the Trail Making Test Part B Between Adoptees With High and Low Genetic Risk for Schizophrenia Spectrum Disorders: The Finnish Adoptive Family Study of Schizophrenia

open access: yesEuropean Journal of Neuroscience, Volume 62, Issue 8, October 2025.
Genetic risk alone did not predict impaired TMT‐B performance, challenging the view that cognitive abnormalities represent an endophenotype of schizophrenia. Psychiatric morbidity was strongly associated with poorer test performance, suggesting that psychopathology impairs executive functioning.

The Temporal and Spatial Responses of Large and Medium Mammals to Anthropogenic Disturbances in Montane Southwest China

open access: yesEcology and Evolution, Volume 15, Issue 9, September 2025.
This study provides new insights for conserving rare wildlife in southwest China's mountainous regions, highlighting the importance of using camera traps to directly monitor anthropogenic disturbance and quantify its impact on species survival. The varying responses of threatened medium and large mammals to human activities emphasize the spatiotemporal

A Nekrasov–Okounkov formula for Macdonald polynomials [PDF]

open access: yesJournal of Algebraic Combinatorics, 2017
We prove a Macdonald polynomial analogue of the celebrated Nekrasov-Okounkov hook-length formula from the theory of random partitions. As an application we obtain a proof of one of the main conjectures of Hausel and Rodriguez-Villegas from their work on mixed Hodge polynomials of the moduli space of stable Higgs bundles on Riemann surfaces.

Ascidians increase in abundance on tropicalized reefs and may enhance benthic nitrous oxide production

open access: yesLimnology and Oceanography, Volume 70, Issue 9, Page 2618-2631, September 2025.
Abstract Nitrous oxide (N2O) is an ozone‐depleting greenhouse gas that has a global warming potential nearly 300 times greater than carbon dioxide. Although the oceans contribute about 21% of atmospheric global N2O emissions, we know relatively little about N2O dynamics in nearshore systems. Here, we document the fourfold increase in the abundance of a

Wreath Macdonald operators

open access: yesForum of Mathematics, Sigma
We construct a novel family of difference-permutation operators and prove that they are diagonalized by the wreath Macdonald P-polynomials; the eigenvalues are written in terms of elementary symmetric polynomials of arbitrary degree.

An Explicit Factorization of the Green's Function for an Acoustic Half‐Space Problem with Impedance Boundary Conditions into an Oscillatory Exponential and a Slowly Varying Function

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 13, Page 12807-12812, September 2025.
ABSTRACT In this paper, new representations of the Green's function for an acoustic d$$ d $$‐dimensional half‐space problem with impedance boundary conditions are presented. The main features of the new representation are in addition to additive terms that appear also in the case of Dirichlet or Neumann boundary conditions, the remaining part of the ...

Generalized $$\beta $$ β and (q, t)-deformed partition functions with W-representations and Nekrasov partition functions

open access: yesEuropean Physical Journal C: Particles and Fields
We construct the generalized $$\beta $$ β and (q, t)-deformed partition functions through W representations, where the expansions are respectively with respect to the generalized Jack and Macdonald polynomials labeled by N-tuple of Young diagrams.
