Laser Induced Damage Studies in Borosilicate Glass Using nanosecond and sub nanosecond pulses

open access: yes, 2016
The damage mechanism induced by laser pulse of different duration in borosilicate glass widely used for making confinement geometry targets which are important for laser driven shock multiplication and elongation of pressure pulse, is studied.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Implementation of the Quasi-Brittle Damage Model for 2024 Aluminum Alloy under Periodic Loading [PDF]

open access: yesInternational Journal of Advanced Design and Manufacturing Technology, 2019
Damage mechanics is one of the most important parts of mechanical engineering that determines the time life for different mechanical elements. The most various models that have been provided so far in damage mechanics, are related to ductile or brittle ...

Uniaxial Compression Damage Mechanical Properties and Mechanisms of Dolomite Under Deep High-Humidity Condition

open access: yesFrontiers in Materials, 2022
The paper studies the uniaxial compression mechanical properties of pillars under the deep and high-humidity environment. We make the pillars cored from the −750 m mine room of Wengfu Phosphate Mine into the standard dolomite samples and test with a ...

Fatigue crack growth in thin notched woven glass composites under tensile loading. Part II: modelling [PDF]

open access: yes, 2011
Fatigue propagation of a through-the-thickness crack in thin woven glass laminates is difficult to model when using homogeneous material assumption. Crack growth depends on both the fatigue behaviour of the fibres and of the matrix, these two phenomena ...

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Cooperative mixing induced surface roughening in bilayer metals: a possible novel surface damage mechanism

open access: yes, 2004
Molecular dynamics simulations have been used to study a collective atomic transport phenomenon by repeated Ar$^+$ irradiations in the Ti/Pt interfacial system. The ion-induced injection of surface atoms to the bulk, the ejection of bulk atoms to the top

Cytotoxicity of the Bacillus thuringiensis Crystal Protein against Mammalian Cells [PDF]

open access: yes, 2002
The crystal proteins produced by Bacillus thuringiensis subsp, israelensis (Bti) and subsp. coreanensis A1519 strain were examined for the cytotoxicity against MOLT-4 and HeLa cells by MTT assay and LDH assay, The A1519 crystal proteins processed by ...
