Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Self-loosening behavior of bolt in curvic coupling due to materials ratcheting at thread root
Advances in Mechanical Engineering, 2019 This article presents the bolt self-loosening mechanism in curvic coupling due to the structural ratcheting under cyclic loading. Finite element simulations are carried out under several loading conditions with different preloads and cyclic torque ...

Biological 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 ...

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

Zirconium Δ-Hydrides: Strain Localisation, Ratcheting, and Fatigue Crack Propagation
International Journal of PlasticityAs many nations commit to achieving Net Zero, many low carbon scenarios indicate that civil nuclear power generation and the economics thereof are set to play a vital role. To maximise nuclear reactor operation lifetimes, it is essential to develop mechanistic understanding of failure and degradation mechanisms in safety-critical components for ...
