Factorization numbers of finite abelian groups [PDF]
International Journal of Group Theory, 2013 The number of factorizations of a finite abelian group as the product of two subgroups is computed in two different ways and a combinatorial identity involving Gaussian binomial coefficients is presented.

On divisors of binomial coefficients, I
Journal of Number Theory, 1985 It is a well-known conjecture that for \(n>4\), the middle binomial coefficient \(\binom{2n}{n}\) is never squarefree. In this paper it is shown that this conjecture is true for all sufficiently large n. More precisely, let \(\binom{2n}{n}=s(n)^2 q(n)\) be the unique decomposition into a square \(s(n)^ 2\) and a squarefree integer q(n).

An Investigation of Hyperostosis Frontalis Interna in a Modern Anatomical Body Donor Population
Clinical Anatomy, EarlyView.ABSTRACT This research sought to examine the prevalence and severity of hyperostosis frontalis interna (HFI) in the Chicagoland anatomical body donor population. The study further aimed to elucidate potential demographic risk factors for HFI, including sex, age at death, and structural vulnerability index (SVI), as well as any common comorbidities, as ...

Restricted Tweedie stochastic block models
Canadian Journal of Statistics, EarlyView.Abstract The stochastic block model (SBM) is a widely used framework for community detection in networks, where the network structure is typically represented by an adjacency matrix. However, conventional SBMs are not directly applicable to an adjacency matrix that consists of nonnegative zero‐inflated continuous edge weights.

A Cross‐Cultural and Developmental Investigation of the Association Between Color and Temperature
Color Research &Application, EarlyView.ABSTRACT The perception of colors involves many contexts in which human beings develop connections. Colors and temperatures are seemingly unrelated concepts, yet our brains have created ways of linking them. According to the literature, primarily from Western cultures, colors such as red and yellow are typically associated with warmth, whereas blue is ...
