On the Square Factors of Central Binomial Coefficients

This preprint provides an exhaustive mathematical treatise on the Erdős Square-Free Binomial Coefficient Conjecture (Problem #32 in Paul Erdős' collection, 1975), a renowned problem in multiplicative number theory and prime factor distributions. The conjecture asserts that for every integer n > 4, the central binomial coefficient C(2n, n) = (2n)! / (

A cross‐sectional study of intimate partner violence and associated factors in women with high‐risk pregnancies: Implications for perinatal care in a tertiary obstetrics hospital

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective This study estimates the prevalence of intimate partner violence during pregnancy (IPVP) and identifies associated psychosocial and mental health factors among women with high‐risk pregnancies. Materials and Methods A cross‐sectional study was conducted among 199 women with high‐risk pregnancies attending a tertiary obstetrics and ...

Conserved SERPINE2 function maintains ovarian estrogen production to support fertility in goats and mice

iMetaOmics, EarlyView.
Single‐nucleus RNA sequencing and functional profiling of goat ovaries with divergent litter sizes revealed prolificacy‐associated granulosa cell (GC) states characterized by enhanced proliferation‐ and steroidogenesis‐related features, together with altered predicted cell–cell communication.

Benchmarking gut microbiome indices within and across populations

iMetaOmics, EarlyView.
We compared 10 widely used gut microbiome indices in 12,561 American Gut Project participants and 10 external cohorts, testing how well each distinguished people with healthy lifestyles, responded to 79 environmental factors, and associated with 14 chronic conditions. No single index performed best on all three tasks.

Catalan Bounds for Symmetric Strength‐Two Orthogonal Arrays

Journal of Combinatorial Designs, EarlyView.
ABSTRACT A Hamming shell construction is a two‐level array obtained by taking every binary vector of a given Hamming weight a prescribed number of times, for each weight in turn. Such arrays are invariant under all permutations of the factors, and they are strength‐two orthogonal arrays exactly when the multiplicities satisfy three linear constraints ...

Childhood adversity and psychotic‐like experiences in adolescence: Investigating a pathway via disrupted pubertal and grey matter development

JCPP Advances, EarlyView.
Abstract Background Childhood adversity increases psychosis risk, but the biological mechanisms responsible remain elusive. A possible but underexplored pathway involves altered pubertal and grey matter (GM) development. Methods In youth from the Adolescent Brain Cognitive Development study (N = 3462), we investigated the effect of adversity at age 9 ...
