Mapping the strain-localization evolution of grain boundary and its interactions with slip/twin at the microscale

Journal of Magnesium and Alloys
Plastic strain in polycrystalline metals is highly localized in grain boundaries (GBs), slip bands (SBs) and twins. While extensive research has focused on intra-granular deformation mechanisms such as slip and twinning, strain localization at GBs has ...

How phagocytic cells kill bacteria: Lessons from a professional killer

FEBS Open Bio, EarlyView.
How phagocytic cells ingest and kill bacteria has been studied for more than a century, but many questions remain unanswered. The study of the amoeba Dictyostelium discoideum brings new answers, and new questions. Professional phagocytic cells such as neutrophils and macrophages, as well as free‐living soil amoebae like Dictyostelium discoideum, employ

Mathematical analysis of strain localization [PDF]

Revue Européenne de Génie Civil, 2007
ABSTRACT First it is shown by a simple one-dimensional example that stress-strain laws with softening cannot provide an objective description of response on the structural level. The phenomenon of discontinuous bifurcation from a uniform state is then analyzed in a general threedimensional setting.

Pathways and pitfalls: a qualitative study of student experiences in biomedical science education

FEBS Open Bio, EarlyView.
Biomedical science students from underrepresented backgrounds face barriers including financial strain, disrupted laboratory access and cultural exclusion. Peer networks provide vital support when institutional systems are difficult to navigate. To create inclusive learning environments and achieve academic success, educators should blend active, hands‐

Strain localization, strong discontinuities and material fracture: matches and mismatches [PDF]

, 2020
The work focuses on the connections of strain localization modeling of material failure and discrete fracture mechanics. It is an attempt to give an answer to the old question of whether the finite element solutions of material failure problems based on ...

Dissolution–precipitation creep in polymineralic granitoid shear zones in experiments – Part 1: Strain localization mechanisms [PDF]

Solid Earth
Dissolution–precipitation creep (DPC) is considered to be one of the main processes accommodating localized strain in polymineralic shear zones of the Earth's crust.

Risk Prediction Models for Recurrence After Curative Treatment of Early‐Stage or Locally Advanced Lung Cancer: A Systematic Review

Aging and Cancer, EarlyView.
This systematic review synthesizes prognostic models for survival and recurrence in resected non‐small cell lung cancer. While many models demonstrate moderate to good discrimination, few are externally validated and reporting quality is variable, limiting clinical applicability and highlighting the need for robust, transparent model development ...

Drug Effect Unveils Inter-head Cooperativity and Strain-dependent ADP Release in Fast Skeletal Actomyosin [PDF]

, 2009
Amrinone is a bipyridine compound with characteristic effects on the force-velocity relationship of fast skeletal muscle, including a reduction in the maximum shortening velocity and increased maximum isometric force.
