Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications

open access: yesThe Anatomical Record, EarlyView.
Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Involvement of the actin cytoskeleton and homotypic membrane fusion in ER dynamics in Caenorhabditis elegans [PDF]

open access: yes, 2005
The endoplasmic reticulum (ER) is the major intracellular membrane system. The ER is essential for protein and lipid biosynthesis, transport of proteins along the secretory pathway, and calcium storage.

A Study on Hourglass-Worm Gearing Designed to Concentrate Surface Normals. A Gear Design Using an Hourglass-Worm Gearing Whose Worm Tooth Surface Is Generated by the Grinding Wheel with an Involute Helicoid.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1991
Displacement of the worm axis relative to the wheel axis under load is considered to be the helical movement rotating about the instantaneous axis. In order to avoid the influence of the displacement of gear axes under load upon tooth contact, the authors propose that the surface normals should be intersected perpendicular to the direction of helical ...

Performance analysis of strengthening reinforced concrete beams under pure torsion using galvanized steel sheets: Experimental and numerical investigation

open access: yesStructural Concrete, EarlyView.
Abstract Reinforced concrete (RC) beams can be subjected to torsion, and failure due to torsion is brittle and poses a significant risk to occupants. Moreover, strengthening of existing RC beams in torsion may be required due to the upgrade of the structures or as part of structural rehabilitation.

Sensitivity study on accuracy and relevant parameters in numerical modeling of internal tendon breaks

open access: yesStructural Concrete, EarlyView.
Abstract This study investigates the numerical modeling of internal tendon breaks in prestressed concrete structures and evaluates the key parameters affecting accuracy. A combined approach is followed, involving global sensitivity analysis via the Elementary Effects Method and subsequent model calibration using experimental data from distributed fiber‐

Wild pig habitat use impacted by prescribed fire in the William B. Bankhead National Forest, USA

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 4, May 2026.
Natural resource management activities like integrated wild pig control programs and 3–5‐year interval prescribed burning can reduce wild pig activity and habitat but can have an unintended side effect of allowing them to thrive in sensitive and protected areas, where access and tools are restricted.

An exquisitely preserved young iguanodontian from the Upper Jurassic of Tanzania sheds light on skeletal fusion patterns within Archosauria

open access: yesPapers in Palaeontology, Volume 12, Issue 3, May/June 2026.
Abstract Dysalotosaurus lettowvorbecki (Ornithopoda, Dinosauria) is a small‐sized dryosaurid iguanodontian known from various isolated remains collected from the Tendaguru Formation (Upper Jurassic, Tanzania). Micro‐computed tomography of a small individual encased in a block offered a unique opportunity to describe c.

open access: yes, 1978
International audienceError concealment (EC) is one of the target applications of inpainting techniques. Some methods combine the estimated lost motion vectors (MVs) with the exemplar-based inpainting technique to recover the lost regions.
