The Release of Non‐Native Gamebirds Is Associated With Amplified Zoonotic Disease Risk
Spillback is potentially an important mechanism by which non‐natives contribute to zoonotic disease emergence. We capitalise on quasi‐experimental releases of non‐native pheasants (Phasianus colchicus) to compare native pathogen prevalence between sites with similar local conditions but different non‐native densities. Prevalence of Borrelia sp.

Macdonald’s polynomials and representations of quantum groups [PDF]
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).

Enumeration of Cylindric Plane Partitions [PDF]
Cylindric plane partitions may be thought of as a natural generalization of reverse plane partitions. A generating series for the enumeration of cylindric plane partitions was recently given by Borodin.

Abstract We use longitudinal data on the social networks of Chinese immigrants in the United States from 2018 to 2020 to study the impact of the COVID‐19 pandemic on communication frequency and friendship formation. Understanding the pandemic's effect on social networks is important because, while individual social networks are always in flux (Schaefer

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.

Noncommutative symmetric functions with matrix parameters [PDF]
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

A raising operator formula for Macdonald polynomials [PDF]
We give an explicit raising operator formula for the modified Macdonald polynomials $\tilde{H}_{\mu }(X;q,t)$, which follows from our recent formula for $\nabla$ on an LLT polynomial and the Haglund-Haiman-Loehr formula expressing modified Macdonald polynomials as sums of LLT polynomials.

ABSTRACT This paper addresses the use of nonparametric kernel density estimation (KDE) to estimate point‐based data density in spatial modeling using Geographic Information Systems (GIS). The paper highlights challenges in selecting the appropriate settings for generating the best fitting KDE surfaces and validating their accuracy, as many GIS packages

Standard fillings to parking functions [PDF]
The Hilbert series of the Garsia-Haiman module can be written as a generating function of standard fillings of Ferrers diagrams. It is conjectured by Haglund and Loehr that the Hilbert series of the diagonal harmonics can be written as a generating ...

Compact formulas for Macdonald polynomials and quasisymmetric Macdonald polynomials [PDF]
We present several new and compact formulas for the modified and integral form of the Macdonald polynomials, building on the compact "multiline queue" formula for Macdonald polynomials due to Corteel, Mandelshtam and Williams. We also introduce a new quasisymmetric analogue of Macdonald polynomials. These quasisymmetric Macdonald polynomials refine the
