Non-local fractional model of rate independent plasticity [PDF]
, 2013 In the paper the generalisation of classical rate independent plasticity using fractional calculus is presented. This new formulation is non-local due to properties of applied fractional differential operator during definition of kinematics.

Establishment of damage estimation rule for brittle fracture after cyclic plastic prestrain in steel [PDF]
MATEC Web of Conferences, 2019 Material damage caused by complicated prestrain like cyclic prestrain and various direction prestrain. It is so important to understand the mechanism of material damage for high-precision lifetime evaluation of steel structure. Material damage depends on

The mechanisms of grain growth of Mg alloys: A review
Journal of Magnesium and Alloys, 2022 Grain growth directly influences the plasticity and strength of Mg alloys. As the grain size decreases from the microscale to the nanoscale, the plasticity of Mg alloys continually increases, whereas the strength first increases and later decreases ...

Dissipative scale effects in strain-gradient plasticity: the case of simple shear
, 2015 We analyze dissipative scale effects within a one-dimensional theory, developed in [L. Anand et al. (2005) J. Mech. Phys. Solids 53], which describes plastic flow in a thin strip undergoing simple shear.

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 ...

Numerical simulation of bearing capacity of a strip footing on strain-softening soil ground
Yantu gongcheng xuebao, 2019 To overcome the mesh sensitivity induced by strain softening, an implicit gradient plasticity model is put forward to simulate the bearing capacity of a rigid strip foundation on strain-softening soil.

Modeling the hall-petch effect with a gradient crystal plasticity theory including a grain boundary yield criterion [PDF]
, 2013 . A strain gradient crystal plasticity theory including the gradient of the equiv- alent plastic strain ∇γeq is discussed. A grain boundary yield condition is proposed in order to account for the influence of the grain boundaries ...

FEBS Open Bio, EarlyView.ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.
