Combination of fracture and damage mechanics for numerical failure analysis

, 1999
A new approach for the analysis of crack propagation in brittle materials is proposed, which is based on a combination of fracture mechanics and continuum damage mechanics within the context of the finite element method.

Multifunctionality and control of the crumpling and unfolding of large-area graphene [PDF]

, 2012
Crumpled graphene films are widely used, for instance in electronics energy storage, composites and biomedicine. Although it is known that the degree of crumpling affects graphene’s properties and the performance of graphene-based devices and materials ...

Development of a High Strength Mg-9Li Alloy via Multi-Pass ECAP and Post-Rolling

Metals, 2019
In this study, a high-strength Mg-9Li alloy was developed via multi-pass equal-channel-angular-pressing (ECAP) and post rolling, of which the yield tensile stress (YTS) and ultimate tensile stress (UTS) were 166 MPa and 174 MPa representing about 219 ...

Transcriptional profiling of circulating extracellular vesicles from prebiopsy prostate cancer patients

Molecular Oncology, EarlyView.
RNA profiling of circulating extracellular vesicles (EVs) from blood samples of men undergoing prostate biopsy identifies transcripts associated with clinically significant prostate cancer. Integrative analysis with public tumor datasets links EV‐derived gene signatures to tumor stage and progression‐free survival, highlighting CASP3, XRCC2, and RIT1 ...

Proceedings of the IUTAM Symposium on Mechanical Behavior and Micro-Mechanics of Nanostructured Materials

, 2007
Recently, we have seen that nano-structured materials demonstrate remarkable advantages over conventional ones, particularly in mechanical behaviors. Thiswill have a great impact on new technology and engineering in the new millennium. In accordance with

Interpreting the effects of DNA polymerase variants at the structural level

Molecular Oncology, EarlyView.
Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

Mechanical behavior and size effect of the staggered bio-structure materials

, 2018
Staggered structure materials, or "brick and mortar" structure materials, are widely observed in natural biomaterials. In this paper, based on strain gradient theory, a trans-scale shear-lag model is developed to characterize the mechanical properties ...

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

Molecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.
