Projecting Low Dimensional Chaos from Spatio-temporal Dynamics in a Model for Plastic Instability

, 2013
We investigate the possibility of projecting low dimensional chaos from spatiotemporal dynamics of a model for a kind of plastic instability observed under constant strain rate deformation conditions.

Stochastically forced dislocation density distribution in plastic deformation [PDF]

Physical Review E, 2016
The dynamical evolution of dislocations in plastically deformed metals is controlled by both deterministic factors arising out of applied loads and stochastic effects appearing due to fluctuations of internal stress. Such type of stochastic dislocation processes and the associated spatially inhomogeneous modes lead to randomness in the observed ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

A constitutive model optimizing superalloy performance: The interplay of annealing twins, dislocations, and grain boundaries

Journal of Materials Research and Technology
The room temperature mechanical properties and formability of heat-treated ultrathin nickel-based superalloys are significantly influenced by annealing twins, dislocations, and grain boundaries. To elucidate the mechanistic roles of these microstructural

Plastic damage evolution in structural steel and its non-destructive evaluation

Journal of Materials Research and Technology, 2020
This paper reports the plastic damage evolution in low carbon structural steel and its NDT evaluation. The SEM observations reveal that the voids initiation, growth, coalescence, micro-crack propagation, and macro-crack formation are the main failure ...

Melting as a String-Mediated Phase Transition

, 2000
We present a theory of the melting of elemental solids as a dislocation-mediated phase transition. We model dislocations near melt as non-interacting closed strings on a lattice.

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

FEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

The positron and mechanical parameters of a cold-worked aluminum alloy (3004) Using PALT, PADBT and HV**

Journal of the Mechanical Behavior of Materials, 2022
In the present work, the influence of plastic deformation on the properties of a 3004 Al-alloy was studied with different techniques. Crystallite size, dislocation density, defect density, micro-strain, and stored dislocation energy are presented and ...

Dislocations and vortices in pair-density-wave superconductors [PDF]

Nature Physics, 2008
With the ground breaking work of the Fulde, Ferell, Larkin, and Ovchinnikov (FFLO), it was realized that superconducting order can also break translational invariance; leading to a phase in which the Cooper pairs develop a coherent periodic spatially oscillating structure.

Day/night variations of myeloid and lymphoid cell subsets in the murine inguinal lymph node

FEBS Open Bio, EarlyView.
The circadian system is involved in the temporal regulation of the immune system. Our study reveals that two innate immune populations, NKT cells and neutrophils, predominate at the beginning of the day in healthy mice, highlighting how the time of day influences immune responses.
