Sensory trait variation in an echolocating bat suggests roles for both selection and plasticity [PDF]

, 2014
Background: Across heterogeneous environments selection and gene flow interact to influence the rate and extent of adaptive trait evolution. This complex relationship is further influenced by the rarely considered role of phenotypic plasticity in the ...

Calibration of the hardening soil model in excalibre

Acta Polytechnica CTU Proceedings
The hardening soil model is one of the most commonly used constitutive models in engineering practice. This model is based on multi-surface plasticity and combines the well-known Mohr-Coulomb failure criterion, a hardening shear surface and a cap yield ...

The modified cyclic multi-surface plastic model of sandy soil based on damping ratio

IOP Conference Series: Earth and Environmental Science, 2020
Abstract Traditional multi-surface plastic model always overestimates the accumulated plastic strain when it is applied into sandy soil under cyclic loading. Considering this overestimation can be reflected through equivalent damping ratio of the hysteretic loop and the damping ratio can also include the real anisotropic plastic ...

Epigenetic heterogeneity and plasticity in therapy‐induced tumor states through single‐cell multi‐omics

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.

Finite deformation of particulate geomaterials: frictional and anisotropic Critical State elasto-plasticity [PDF]

, 2011
This thesis is concerned with the theoretical development and numerical implementation of efficient constitutive models for the analysis of particulate media (specifically clays) in structures undergoing geometrically non-linear behaviour.

Surface-Mounted Distributed Fiber Optic Sensor Measurements, and Concrete Damaged Plasticity Modeling for Damage Analysis of Reinforced Concrete Beams

, 2021
Structural health monitoring (SHM) has become an integral part of essential and costly to replace infrastructures such as bridges and buildings which degrade during their lifetime.

On the Lightweight Potential of Laser Additive Manufactured NiTi Triply Periodic Minimal Sheet Lattices

Advanced Engineering Materials, EarlyView.
This study explores the lightweight potential of laser additive‐manufactured NiTi triply periodic minimal surface sheet lattices. It systematically investigates the effects of relative density and unit cell size on surface quality, deformation recovery, compression behavior, and energy absorption.

Adaptive plasticity in the mouse mandible [PDF]

, 2014
Background: Plasticity, i.e. non-heritable morphological variation, enables organisms to modify the shape of their skeletal tissues in response to varying environmental stimuli.

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Influence of the Yield Surface Curvature on the Forming Limit Diagrams Predicted by Crystal Plasticity Theory [PDF]

, 2016
The aim of this paper is to investigate the impact of the microscopic yield surface (i.e., at the single crystal scale) on the forming limit diagrams (FLDs) of face centred cubic (FCC) materials.
