Kinetic Contribution to the Arbitrary Order Odd Frequency Moments of the Dynamic Structure Factor

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT An exact expression is derived for the kinetic contribution to the odd (arbitrary order) frequency moments of the dynamic structure factor via a finite summation that features averages of even (all lower orders) powers of the momentum over the exact momentum distribution.

Self‐Reported Versus Objectively Logged Social Media Use: Implications for Measurement in Eating Disorder Research

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Self‐reported frequency measures of social media use (e.g., “How often do you use social media?”) are convenient, yet their criterion validity against objective behavioral data remains largely untested in eating disorder research. We compared self‐reports of TikTok use with objective data extracted from TikTok datafiles.

Steering Industrial Decarbonisation: Explaining OECD Policy Variation

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT The ongoing rise in CO2 emissions driven by energy‐intensive industries highlights the urgent need for targeted policy interventions, with national strategies playing a crucial role in the low‐carbon transition. However, the factors that shape the ambition of industrial decarbonisation policies remain poorly understood.

Central and local limit theorems for the coefficients of polynomials of binomial type

open access: yesJournal of Combinatorial Theory, Series A, 1977
AbstractWe introduce the problem of establishing a central limit theorem for the coefficients of a sequence of polynomials Pn(x) of binomial type; that is, a sequence Pn(x) satisfying exp(xg(u)) = ∑n=0∞ Pn(x)(unn!) for some (formal) power series g(u) lacking constant term.

Forecasting heart failure: Seasonal alignment of heart failure outcomes in New York

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 819-831, April 2025.
Abstract Background Seasonal variations have been observed in heart failure (HF) hospitalization. Numerous explanatory mechanisms have been proposed, but no prior studies have examined potential contributors directly. Our objective was to identify specific factors that could contribute to seasonal variability using a large longitudinal dataset of HF ...

National Football Teams’ Performance Predicts Spectators’ Identities, Affect and Sociopolitical Attitudes: An Investigation During the 2024 EURO Tournament

open access: yesEuropean Journal of Social Psychology, EarlyView.
ABSTRACT On the basis of two social‐affective frameworks, we posited that national football team performance (winning vs. losing) would impact spectators’ identities, affect and sociopolitical attitudes—including their intergroup attitudes (i.e., in‐group favouritism and multiculturalism) and societal perceptions (i.e., national optimism, perceived ...

Congruences involving the reciprocals of central binomial coefficients

open access: yes, 2009
We present several congruences modulo a power of prime $p$ concerning sums of the following type $\sum_{k=1}^{p-1}{m^k\over k^r}{2k\choose k}^{-1}$ which reveal some interesting connections with the analogous infinite series.

Ultrafast oscillations in the human brain and their functional significance

open access: yesEpilepsia, EarlyView.
Abstract Objective The upper frequency limit of human brain activity remains unknown. Using ultrahigh sampling rate (≥20 kHz) intracranial microelectroencephalography, this study aimed to systematically explore and quantitatively characterize brain field oscillations beyond the established high‐frequency oscillation range (>2 kHz), and to determine ...

Accuracy of the rapid‐response electroencephalography's Automated Seizure Burden Estimator: A follow‐up validation study of version 8 (AccuRASE II)

open access: yesEpilepsia, EarlyView.
Abstract Objective Ceribell Inc.'s point‐of‐care electroencephalographic (EEG) system and artificial intelligence‐based Automated Seizure Burden Estimator (ASBE; ClarityPro) have US Food and Drug Administration clearance for diagnosing electrographic status epilepticus (ESE).

Asymptotic Expansions of Central Binomial Coefficients and Catalan Numbers

open access: yesJ. Integer Seq., 2013
We give a systematic view of the asymptotic expansion of two well-known sequences, the central binomial coefficients and the Catalan numbers. The main point is explanation of the nature of the best shift in variable $n$, in order to obtain ``nice'' asymptotic expansions. We also give a complete asymptotic expansion of partial sums of these sequences.
