Deep phenotyping of coarse root architecture in R. pseudoacacia reveals that tree root system plasticity is confined within its architectural model. [PDF]
PLoS ONE, 2013 This study aims at assessing the influence of slope angle and multi-directional flexing and their interaction on the root architecture of Robinia pseudoacacia seedlings, with a particular focus on architectural model and trait plasticity.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level
Aging and Cancer, EarlyView.This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

3D nonlinear coupled modelling of geomaterials using the unconventional Subloading Surface approach [PDF]
, 2013 The purpose of the work presented in this thesis is aimed to investigate the nonlinear behaviour of porous media, in detail soils, by means of an unconventional plasticity model named subloading surface.

Calibration of the hardening soil model in excalibre
Acta Polytechnica CTU ProceedingsThe 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 ...

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

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 ...

Advanced Engineering Materials, EarlyView.A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

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.
