Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part II Deriving instrument‐specific correction equations for meta‐analyses using published data

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.

Hochschild cohomology of group extensions of quantum symmetric algebras [PDF]

, 2010
Quantum symmetric algebras (or noncommutative polynomial rings) arise in many places in mathematics. In this article we find the multiplicative structure of their Hochschild cohomology when the coefficients are in an arbitrary bimodule algebra. When this

Skew Polynomial Extensions over Zip Rings [PDF]

International Journal of Mathematics and Mathematical Sciences, 2008
In this article, we study the relationship between left (right) zip property of R and skew polynomial extension over R, using the skew versions of Armendariz rings.

Lifespan Pancreas Morphology for Control Versus Type 2 Diabetes Using AI on Largescale Clinical Imaging

Clinical Anatomy, EarlyView.
ABSTRACT Understanding how pancreas size and shape change with normal aging is critical for establishing a baseline to detect deviations in type 2 diabetes and other pancreatic disease. We measure pancreas size and shape using morphological measurements from early development through aging (ages 0–90).

Decoding Emotional Signatures of Ethical Ads: An Analysis of Actor‐Viewer Synchrony

Journal of Consumer Behaviour, EarlyView.
ABSTRACT We examine whether ethical advertisements differ from conventional ads in their on‐screen emotional signatures and whether those signatures transfer to actor‐viewer synchrony. Study 1 analyses 138 professionally produced YouTube ads using Automated Facial Expression Recognition (AFER) and Convolutional Neural Networks (CNN) to quantify actor ...

DIEUDONNÉ DETERMINANTS FOR SKEW POLYNOMIAL RINGS [PDF]

Journal of Algebra and Its Applications, 2006
We observe that the Dieudonné determinant induces a non-negative degree function on the ring of matrices over a skew polynomial ring. We then apply this degree function to two examples. In the first one, we find an expression for the rank of the kernel of an algebraic endomorphism of [Formula: see text] over a field of characteristic p > 0.

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.

Around Zero-Divisor Graph of Skew Polynomial Rings over Real Matrix 2 by 2

Journal of Physics: Conference Series, 2019
Let R be an associative ring with non-zero two-sided multiplicative identity. The zero-divisor of R, denoted by Z (R). The directed graph Γ(R) is a graph with vertices Z (R) − {0}, where x → y is an edge between distinct vertices x and y if and only if ...

The prevalence of food insecurity and its relationship with wellbeing in a large, cross‐sectional study of children and young people in England

JCPP Advances, EarlyView.
AbstractBackgroundWe aimed to assess the prevalence of food insecurity reported by children and young people in four areas of England in 2023 and examine its association with mental health and wellbeing.MethodsWe used data from the OxWell student survey, a large, diverse, cross‐sectional study of 38,430 students aged 8–19 years, conducted primarily in ...
