The Propagation of Plastic Deformation in Solids [PDF]

Journal of Applied Physics, 1950
The stress wave caused by a longitudinal impact at the end of a cylindrical bar has been analyzed in the case where the impact velocity is large enough to produce plastic strain. The theory gives a method for computing the stress distribution along the bar at any instant during impact.

Investigations on the tensile deformation of pure Mg and Mg–15Gd alloy by in-situ X-ray synchrotron radiation and visco-plastic self-consistent modeling

Journal of Magnesium and Alloys, 2023
In this study, the texture evolutions of two Mg materials during tension are explored. In-situ X-ray synchrotron and Visco-Plastic Self-Consistent (VPSC) modeling are employed to investigate the different deformation modes between pure Mg and Mg–15Gd (wt.

Optimizing weathering steel tie rod production for sustainable greenhouse structures

Scientific Reports
The current paper is based on a case study conducted at an industrial facility in Egypt, which is responsible for processing greenhouse structures. Steel tie rods play a vital role, as they prevent the truss frames from spreading outwards. Irrigation and

Spatial biology in cancer epigenetics

Molecular Oncology, EarlyView.
Spatial epigenomics combines molecular profiling with tissue architecture to reveal how gene regulation is organized within intact tissues. In cancer, these technologies uncover the mechanisms driving tumor heterogeneity and microenvironmental interactions, opening new opportunities for biomarker discovery and precision medicine.

Research on surrounding rock control technology of deep roadway based on butterfly failure theory

Meitan kexue jishu, 2023
At present, roadway surrounding rock control is still one of the major problems in deep mining of coal resources. The formation and development of the plastic zone of the surrounding rock is the main cause of large deformation and failure of roadway.

Guiding AlphaFold to predict how Munc13‐1 opens Syntaxin‐1

FEBS Open Bio, EarlyView.
The syntaxin‐1 Habc‐domain (orange), linker (pink) and SNARE motif (yellow) form a closed conformation that binds to Munc18‐1 (violet) and is opened by the Munc13‐1 MUN domain (cyan) to form the SNARE complex that triggers neurotransmitter release.
