Functional morphology of trabecular bone in the calcaneus of African apes
Journal of Anatomy, EarlyView.Pan exhibits significantly higher calcaneal tuberosity trabecular thickness (Tb.Th) and bone volume fraction (BV/TV) than Gorilla, potentially reflecting higher triceps surae forces for vertical climbing. Both taxa have significantly higher Tb.Th and BV/TV in the anterior calcaneus; the difference is exaggerated in Gorilla, potentially reflecting ...

An Efficient Geometrically‐Exact Nonlinear Shell Formulation Based on Rodrigues Parameters
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.ABSTRACT Thin‐walled structures are part of many engineering applications, as wind turbine blades, pressure vessels, and sheet metal products. A thin‐walled structure is characterized by one significantly smaller dimension compared to the others.

The dynamics of cracks in torn thin sheets
, 2010 Motivated by recent experiments, we present a study of the dynamics of cracks in thin sheets. While the equations of elasticity for thin plates are well known, there remains the question of path selection for a propagating crack.

Deformation‐Induced Formation of Stray Grains in Additive Manufacturing of Single Crystals
Advanced Science, Volume 13, Issue 25, 4 May 2026.Stray grain formation severely limits the additive manufacturing of single‐crystal alloys. By integrating in situ synchrotron techniques, ex situ characterization, and multi‐scale multi‐physics modeling, the authors reveal that stray grains originate from dislocations at the solid‐liquid interface, rather than thermal supercooling in conventional ...

A control volume based formulation of the discrete Kirchoff triangular thin plate bending element [PDF]
, 2009 A control volume method is presented for predicting the displacement and rotation of thin transversely loaded flat plates. The new procedure uses discrete Kirchoff triangle (DKT) elements but introduces a dual mesh of interconnected control volumes (CVs)

Sub‐100 Nanometer Focusing of Hard X‐rays Using SU‐8 Compound Kinoform Focusing Lenses
Advanced Photonics Research, Volume 7, Issue 4, April 2026.A novel aberration‐free X‐ray compound refractive lens design based on Cartesian oval curve is presented. Achieving a vertical focal spot size of 70.8 nm using knife‐edge scanning with a 200 μm incident aperture. Wavefront reconstruction via knife‐edge imaging further resolves a refined focal spot of 56 nm.
