A novel method for severe plastic deformation at high strain rate
EPJ Web of Conferences, 2018 Severe plastic deformation (SPD) processing is defined as any method of forming under an extensive hydrostatic pressure that may be used to impart a very high strain to a bulk solid without any significant change in dimensions of the sample, producing ...

FEBS Open Bio, EarlyView.Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Identification de lois de comportement représentatives des conditions d’usinage pour des alliages de titane à différentes teneurs alpha/beta [PDF]
, 2013 Determining a material constitutive law which is representative of the extreme conditions found in the cutting zone during machining operations is a very challenging problem. In this study, dynamic shear tests, which reproduce, as faithfully as possible,

Long‐term hippocampal alterations and cognitive impairment in a murine model of surgical sepsis
FEBS Open Bio, EarlyView.Using a mouse model of surgical sepsis, we tested long‐term memory and analyzed the transcriptome of single cells isolated from the hippocampus. Survivor mice showed worse memory, loss of certain brain cell subpopulations, and abnormal immune cell activity—suggesting that post‐sepsis brain alterations may be linked to cognitive deficits.

High strain rate damage in porous andesite
, 2022 International audienceDeformation rates at volcanoes vary enormously, potentially altering the way in which volcanic rock accommodates strain. However, relationships between deformation rate, damage patterns, and physical properties are poorly understood.

FEBS Open Bio, EarlyView.Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Materials for extreme dynamic loads
, 2022 S.481-507In this paper emphasis is given to attempts to correlate manufacturing parameters and high-strain rate properties of metals and alloys. Investigations up to strain-rates have been performed mainly under tension, some also under compression or ...

Deformation and Ductile Fracture of a Low Alloy Steel under High Strain Rate Loading [PDF]
, 2006 Ductile failure of metals always occurs after a specific amount of plastic deformation. Therefore, the investigation and characterization of the deformation behaviour is required to understand the damage process and to describe the failure by a suitable ...

Shear failure of AA2024 and AA7175 under high strain rate loading
MATEC Web of Conferences, 2018 In the context of the design of aeronautical structures regarding accidental events, we are here investigating and comparing the shear failure of two aluminum alloys, namely AA2024 and AA7175, under high strain rate loading.
