An extended definition of Anosov representation for relatively hyperbolic groups

Journal of Topology, Volume 19, Issue 2, June 2026.
Abstract We define a new family of discrete representations of relatively hyperbolic groups which unifies many existing definitions and examples of geometrically finite behavior in higher rank. The definition includes the relative Anosov representations defined by Kapovich–Leeb and Zhu, and Zhu–Zimmer, as well as holonomy representations of various ...

Degree theory for 4‐dimensional asymptotically conical gradient expanding solitons

Communications on Pure and Applied Mathematics, Volume 79, Issue 5, Page 1151-1298, May 2026.
Abstract We develop a new degree theory for 4‐dimensional, asymptotically conical gradient expanding solitons. Our theory implies the existence of gradient expanding solitons that are asymptotic to any given cone over S3$S^3$ with non‐negative scalar curvature. We also obtain a similar existence result for cones whose link is diffeomorphic to S3/Γ$S^3/\

Feasibility of High‐Density Surface Electromyography for the Detection of Neuromuscular Disorders in Children

Muscle &Nerve, Volume 73, Issue 5, Page 806-814, May 2026.
ABSTRACT Introduction/Aims Diagnosing neuromuscular disorders in children is challenging. Concentric needle electromyography (CNEMG) is the standard for electrophysiological assessments but has limitations in pediatric populations. High‐density surface electromyography (HDsEMG) provides a noninvasive technique with superior spatial resolution, enabling

Post Activation Potentiation Is Greater in Human Triceps Brachii Versus Triceps Surae Muscles

Muscle &Nerve, Volume 73, Issue 5, Page 815-821, May 2026.
ABSTRACT Introduction/Aims Voluntary muscle contractions result in a temporary increase in twitch force, a phenomenon termed post activation potentiation (PAP). In rodents and other species, PAP is observed predominantly or exclusively in fast twitch muscles. However, it has been suggested that in humans, PAP occurs more or less independently of muscle

Application of Group‐Theoretical Approaches in Structural Natural Frequency Analyses

International Journal for Numerical Methods in Engineering, Volume 127, Issue 7, 15 April 2026.
ABSTRACT Group theory has profoundly advanced physics and chemistry in systems with symmetries. Yet its use in structural engineering applications has not yet been fully explored beyond the aesthetics of symmetric designs. This work addresses two significant gaps that have limited the broader adoption of group‐theoretic methods in structural vibration ...

Inline pvT Analysis for Precise Volume Dosing in Injection Molding: Addressing Variability in Recyclate Melts

Journal of Applied Polymer Science, Volume 143, Issue 14, April 10, 2026.
Precise In‐line volumetric dosing despite varying material composition. ABSTRACT Precise volumetric dosing of polymer melts is essential for dimensional stability and mass consistency in injection‐molded samples, particularly when melt compressibility influences the effective volume delivered to the cavity. Conventional approaches rely on reference pvT

A Comparative Study of Cerebral Oxygenation During Exercise in Hemodialysis and Peritoneal Dialysis Patients

Therapeutic Apheresis and Dialysis, Volume 30, Issue 2, Page 245-253, April 2026.
ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

Leveraging Digital Advanced Manufacturing to Enable Polymer Electrolyte Fuel Cells With Ultrahigh Gravimetric Power Density

Advanced Energy Materials, Volume 16, Issue 13, 1 April 2026.
This study employs digital advanced manufacturing to develop lightweight, compact porous distributors as alternatives to conventional bipolar plates in PEM fuel cells. A graphene‐coated nickel foam achieves a power density of 1.52 W cm−2, while titanium‐based designs deliver lightweight solutions: an LPBF‐fabricated Gyroid lattice reaches 1.36 W cm−2 ...

Secular Changes in Cranial Morphology and Pattern of Sexual Dimorphism in Modern Japanese: A Geometric Morphometric Analysis Using Post‐Mortem Computed Tomography Data

American Journal of Biological Anthropology, Volume 189, Issue 4, April 2026.
ABSTRACT Objectives Although human cranial morphology is thought to have undergone changes in various populations over the past century, the details of this three‐dimensional transformation remain largely unknown. To address this problem, we conducted a geometric morphometric analysis of cranial shapes in the historical Japanese group who lived ...
