Study on Ratcheting Effect of Pressurized Straight Pipe with Local Wall Thinning Using Finite Element Analysis

open access: yes, 2015
Ratcheting deformation is studied on straight pipe made of Z2CND18.12N stainless steel with local wall thinning subjected to constant internal pressure and reversed bending using finite element analysis.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

The Cognitive Foundations of Teaching

open access: yesEvolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 2, June 2026.
ABSTRACT The propensity to teach is vital to human cultural evolution and to our ecological dominance of the planet, but its cognitive foundations remain poorly understood. Traditional explanations argue that teaching hinges on particular cognitive pre‐requisites, such as Theory of Mind.

Biaxial Ratcheting Response of SS 316 Steel

open access: yes, 2010
Ratcheting is one of the challenging phenomena that needs to be investigated for the Fast breeder reactor (FBRs), to arrive at the optimum structural dimensions that are safe and yet do not have undue redundancy.

Reliability and Validity of Ankle Muscle Strength Testing Using the ISOTIB Device

open access: yesJournal of Foot and Ankle Research, Volume 19, Issue 2, June 2026.
ABSTRACT Introduction One repetition maximum (1RM) testing is recognised as a reliable and valid method for determining maximum muscle strength. However, there are limited reports in the literature for measuring maximum ankle strength using free‐weight methods.

Reconcile the perfectly elastoplastic model to simulate the cyclic behavior and ratcheting

open access: yesInternational Journal of Solids and Structures, 2006
AbstractPerfectly elastoplastic constitutive model is modified through a smoothing factor introduced by Liu [Liu, C.-S., 2003. Smoothing elastoplastic stress–strain curves obtained by a critical modification of conventional models. Int. J. Solids Struct. 40, 2121–2145].

Hybrid Data‐Driven and Physics‐Informed Learning of Cyclic Plasticity For Pipe Steel

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT An efficient and explainable machine learning (ML) approach is presented, replacing conventional material models based on the radial return mapping (RRM) algorithm for the constitutive modeling of cyclic plasticity in 3D. The application of transfer learning, based on an existing model for a separate class of steel, leads to a significant ...

Allosteric Regulation of RNA Affinity by Motif V‐VI Coupling in West Nile Virus NS3 Helicase

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 6, Page 1212-1224, June 2026.
ABSTRACT The rise of flaviviral diseases, including West Nile virus (WNV), presents a growing threat to global public health and underscores the urgent need for new therapeutic strategies. The non‐structural protein 3 helicase (NS3h) of the Orthoflavivirus genus, including WNV, is essential for viral replication and a promising antiviral target ...
