Directional Variations in Tidal Flow Multifractality and Intermittency

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 6, June 2025.
Abstract We explored distinct directional variations of multifractal and intermittent characteristics of ebb and flood flow velocities at nodule point, WA, tidal energy site, and complementary inspection on the East River, NY using scaling exponents of the structure function, distribution flatness, detrending moving average (DMA) analysis, multifractal

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.

Generalized Tesler matrices, virtual Hilbert series, and Macdonald polynomial operators [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2015
We generalize previous definitions of Tesler matrices to allow negative matrix entries and non-positive hook sums. Our main result is an algebraic interpretation of a certain weighted sum over these matrices.

Clustering properties of rectangular Macdonald polynomials [PDF]

open access: yes, 2012
The clustering properties of Jack polynomials are relevant in the theoretical study of the fractional Hall states. In this context, some factorization properties have been conjectured for the $(q,t)$-deformed problem involving Macdonald polynomials.

Unequal by Design: Ministerial Policy Roles in the Canadian Executive, 2015‐2021

open access: yesCanadian Public Administration, Volume 68, Issue 2, Page 245-263, June 2025.
Abstract Cabinet ministers are formally equal but unequal in practice: for example, ministers may differ significantly in how they undertake policy activity. I use federal mandate letter data from 2015 to 2021 to explore variation in and correlates of ministerial policy activity.

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.

Simulating the Relationship Between Nonword Repetition Performance and Vocabulary Growth in 2‐Year‐Olds: Evidence From the Language 0–5 Project

open access: yesLanguage Learning, Volume 75, Issue 2, Page 379-423, June 2025.
Abstract A strong predictor of children's language is performance on non‐word repetition (NWR) tasks. However, the basis of this relationship remains unknown. Some suggest that NWR tasks measure phonological working memory, which then affects language growth. Others argue that children's knowledge of language/language experience affects NWR performance.

Enumeration of Cylindric Plane Partitions [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
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.

Using Multidelay Discrete Delay Differential Equations to Accurately Simulate Models With Distributed Delays

open access: yesStudies in Applied Mathematics, Volume 154, Issue 6, June 2025.
ABSTRACT Delayed processes are ubiquitous throughout biology. These delays may arise through maturation processes or as the result of complex multistep networks, and mathematical models with distributed delays are increasingly used to capture the heterogeneity present in these delayed processes. Typically, these distributed delay differential equations
