Crack propagation in cortical bone is affected by the characteristics of the cement line: a parameter study using an XFEM interface damage model

open access: yesBiomechanics and Modeling in Mechanobiology, 2019
Bulk properties of cortical bone have been well characterized experimentally, and potent toughening mechanisms, e.g., crack deflections, have been identified at the microscale.

Stress Intensity Factors for Radial Crack on Inner Surface of Interface in Multi-Layer Rotating Thick-Walled Cylinder

open access: yesMetals, 2022
Cracks often appear on the inner surface of metal thick-walled cylinders with multiple interference fits. Considering that no relatively accurate model exists for the cracks on the interface of multi-layered, rotating, thick-walled cylinders, in this ...

Interfacial Stress Development and Cracking Susceptibility during Laser Powder Bed Fusion of Random TiB2-Particle-Reinforced AlSi10Mg Matrix Composites

open access: yesMetals, 2023
A sequentially coupled multi-phase thermo-mechanical model for laser powder bed fusion (LPBF) of Al-based composites reinforced by 1 wt.% random TiB2 micron particles was established.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Cracks propagation characteristics of double-hole delay blasting in soft-hard composite rock mass

open access: yesScientific Reports, 2023
By researching the distance between blasthole and interface of soft-hard rock strata, as well as the time of delay detonation, blasting effect of the rock mass will be more controllable.

Overcoming brittleness of high volume fraction Al/SiCp composites by controlling interface characteristics

open access: yesMaterials & Design, 2022
Particle-reinforced metal matrix composites (MMCs) with high-volume-fraction of above 40% are highly attractive in the field of structural materials because they impart enhanced reinforcement properties to metals.

The effect of a curvature-dependent surface tension on the singularities at the tips of a straight interface crack [PDF]

open access: yes, 2012
A problem of an interface crack between two semi-planes made out of different materials under an action of an in-plane loading of general tensile-shear type is treated in a semi-analytical manner with the help of Dirichlet-to-Neumann mappings.

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Cracking behavior and fracture mechanism of rock-concrete composite interface under different stress conditions: Experimental and numerical approaches

open access: yesCase Studies in Construction Materials
The cracking behavior and mechanical characteristics of rock-concrete (R-C) composite under different stress conditions are crucial for ensuring engineering safety and stability. In this study, a numerical model of R-C composite was established employing
