Annals of Neurology, EarlyView.Objective To characterize magnetic resonance imaging (MRI)‐based glymphatic surrogates in Huntington's disease (HD) using MRI measures of perivascular diffusivity and structural perivascular alterations across multiple large cohorts. Methods We analyzed 2,731 MRI sessions from 880 participants across 3 large retrospective HD cohorts.

Characterizing ϕRic-Vector Fields and Quasi-Einstein Manifolds on Multiply Warped Product Manifolds
International Journal of Mathematics and Mathematical SciencesWe characterize multiply warped product manifolds with ϕRic-vector fields. We give the necessary and sufficient conditions for the lift of a vector field on a factor manifold to be the ϕRic-vector field.

The Warped Product of Hamiltonian Spaces
, 2014 In this paper, the geometric properties of warped product Hamiltonian spaces are studied. It is shown there is a close geometrical relation between a warped product Hamiltonian space and its base Hamiltonian manifolds.

The Anatomical Record, EarlyView.Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

Integrating whole‐bone and regional analyses to understand human scapular growth
The Anatomical Record, EarlyView.Abstract This study investigates ontogenetic changes in human scapular morphology using three‐dimensional geometric morphometrics with whole‐bone and region‐specific analyses. The aim is to evaluate whether the scapula follows a regular developmental pattern and whether its functionally distinct components, the scapular spine (SS) and glenoid fossa ...

Conharmonically flat and conharmonically symmetric warped product manifolds
AIP AdvancesThis article presents characterizations of warped product manifolds based on the flatness and symmetry of the conharmonic curvature tensor. It is proved that when a warped product manifold is conharmonically flat, both the base and fiber manifolds ...

Three‐dimensional geometric morphometric analysis of diaphragmatic dome motion in COPD patients
The Anatomical Record, EarlyView.Abstract Diaphragmatic dysfunction is a hallmark of chronic obstructive pulmonary disease (COPD), especially in emphysema, where hyperinflation alters diaphragm geometry and impairs inspiratory mechanics. However, quantitative three‐dimensional (3D) assessments of diaphragmatic dome shape and motion across COPD phenotypes are limited.

The Anatomical Record, EarlyView.Abstract In a large sample of adult crab‐eating macaques, we quantified sexual dimorphism in size, shape, and covariance across the whole skull and among anatomical regions of the cranium and mandible. All regions showed significant mean sex differences, but the magnitude of size and shape dimorphism varied substantially.

Evolutionary morphology of the haplorhine hamate
The Anatomical Record, EarlyView.Abstract Primates adopt a variety of hand postures during an impressive diversity of locomotor and manipulative behaviors. Morphological research has found that elements of the hand skeleton, such as the hamate, hold key information for inferring hand use and locomotor kinematics in extinct species.
