DYNAMIC STRAIN AGEING IN LiF SINGLE CRYSTALS [PDF]
Le Journal de Physique Colloques, 1973 Dislocation-point defect interactions have been investigated in high purity LiF single crystals containing less than 5 ppm of Mg2+, utilising dynamic strain ageing techniques. Two mechanisms of strain ageing have been found. Below 200 °C, the mechanism is one of weak pinning of dislocations by tetragonal strain fields around impurity-vacancy dipoles ...

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Molecular Oncology, EarlyView.We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

Molecular Oncology, EarlyView.Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.

Effect of Temperature on the Kinetics of Localized Plasticity Autowaves in Lüders Deformation
Metals, 2023 The paper analyzes the elastoplastic transition in Fe–0.025 wt. % C at a temperature of 296–503 K and strain rate of 6.67·10−6–3.33·10−3 s−1. The analysis shows that the lower yield stress increases by a power law with increasing the strain rate, and ...

Dynamic strain aging in DP steels at forming relevant strain rates and temperatures
Materials Science and Engineering: A, 2017 Abstract Mechanical testing of dual phase (DP) steels at low strain rates (10 −3 s −1 ) have shown that they are susceptible to dynamic strain aging (DSA) between 100 °C–400 °C. During industrial forming processes at intermediate strain rates (1–10 2 s −1 ), the local temperatures may rise to the DSA range due to deformation heating which may ...
