A periodic elastic medium in which periodicity is relevant [PDF]

, 2000
We analyze, in both (1+1)- and (2+1)- dimensions, a periodic elastic medium in which the periodicity is such that at long distances the behavior is always in the random-substrate universality class.

Analytical solutions of time-fractional heat order for a magneto-photothermal semiconductor medium with Thomson effects and initial stress

Results in Physics, 2020
The influence of hydrostatic initial stress in the context of the time-fractional heat order equation is investigated. The strong electromagnetic field is applied at the external surface of semiconductor elastic medium during the photothermal transport ...

RIPK4 function interferes with melanoma cell adhesion and metastasis

Molecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

Finite Element Analysis of a Dynamic Linear Crack Problem

East European Journal of Physics
This work investigates the problem of a linear crack in the middle of a uniform elastic medium under normal tension-compression loading. The direct Finite Element numerical procedure is used to solve the fractured media deformation problem, which also ...

Geodesics around line defects in elastic solids

, 1998
Topological defects in solids, usually described by complicated boundary conditions in elastic theory, may be described more simply as sources of a gravity- like deformation field in the geometric approach of Katanaev and Volovich.

Expression of Elastic Deformation of Inhomogeneous Medium by Dislocations Distributed in Homogeneous Elastic Medium

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1983
Discussions are made on the possibility of expressing elastic deformation of an inhomogeneous material by dislocations distributed in a homogeneous elastic medium. A model of the inhomogeneous material is employed, which is composed of plane rectangular regions with different elastic constants.

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

FEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.
