Crack growth resistance in nuclear graphite [PDF]

open access: yes, 2002
R-curve behaviour is often used for evaluating crack growth resistance in quasibrittle materials but few studies have focused on polycrystalline graphite. In this study, R-curve behaviour in three commercial grade nuclear graphites, of varying structure

Three-dimensional crack propagation simulation based on a nonlocal algorithm of P91 steel under fatigue and creep–fatigue loading

open access: yesMechanical Engineering Journal
This study conducted a three-dimensional crack propagation simulation based on a nonlocal algorithm of P91 steel under fatigue and creep–fatigue loading. A damage-coupled inelastic constitutive model incorporating fatigue and creep damage parameters into

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Mechanism of Micro and Macro Mechanics in Brittle Rocks During Cyclic Creep Under High Seepage Pressure

open access: yes工程科学与技术, 2023
Cyclic creep mechanical properties of brittle rock under the combined influence of high seepage pressure, confining pressure, and cyclic axial loading and unloading are of great significance to the stability evaluation of surrounding rock in deep ...

Numerical study of crack path by MMCG specimen using M integral [PDF]

open access: yesFracture and Structural Integrity, 2016
The mixed mode loading configuration occurs in many civil engineering and mechanical applications. In wood material, the study of this problem is very important due to the orthotropic character and the heterogeneity of the material.

Numerical simulation of creep fracture evolution in fractured rock masses

open access: yesFrontiers in Earth Science, 2022
The initiation, expansion, and penetration of microscopic cracks in rock is the macroscopic manifestation of creep. This paper investigates mechanical creep characteristics and fracture evolution processes in rock masses with different fracture angles ...

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

open access: yesFEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

Characterization of crack nucleation in TA6V under fretting-fatigue loading using the potential drop technique [PDF]

open access: yes, 2010
Crack initiation in a Ti-6Al-4V alloy was investigated experimentally in fretting fatigue conditions. A cylinder-plane geometry was used for the contact, and partial slip conditions were considered.
