Failure analysis of carbon fiber reinforced composite countersunk bolt joint
Journal of Aeronautical Materials, 2020 In order to study the initiation, propagation and material failure behavior of T800 carbon fiber reinforced composite joint structure with countersunk bolt under load, the quasi-static tensile tests were carried out on the bolt joint structure. The three-

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

A General Failure Criterion for Frictional and Cohesive Materials
Soils and Foundations, 1986 ABSTRACT The Matsuoka-Nakai failure criterion for a frictional material, and the Von Mises criterion for a cohesive material are expressed in such a way that they are seen to bear similar relationships to the cohesionless Mohr-Coulomb and Tresca criteria respectively.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

A New Criterion for Judging Tunnel Failure by the Strength Reduction Method
Applied SciencesRecently, the application of the strength reduction method (SRM) to tunnel stability research has become a trend. The failure criteria for the SRM in tunnels often draw from those used in slopes.

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

A generalized anisotropic failure criterion for geomaterials
, 2010 Experimental evidence shows that the strength of geomaterials, such as soils and rocks, is significantly influenced by inherent anisotropy and other factors such as shear banding and the intermediate principal stress, which cannot be properly described ...
