Seismic Performance Testing and Damage Analysis of Reinforced T-Stub Connections
BuildingsTo improve the seismic performance of semi-rigid steel frame beam–column joints connected by T-stubs, reinforced T-stubs formed via wedge-shaped and thickening modifications are proposed.

Identification of the continuum damage parameter: An experimental challenge in modeling damage evolution [PDF]
Acta Materialia, 2012 To accurately predict ductile failures of new advanced metals, continuum damage models (CDM's) require experimental determination of material-specific damage parameter(s). While various experimental techniques are being used to determine these damage parameter(s), possible systematic errors due to methodological difference in damage definition have yet

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

3D orthogonal woven carbon/carbon composites: micromechanical modeling and damage analysis
Materials Research ExpressThis study develops a progressive damage model for three-dimensional orthogonal woven car-bon/carbon composites using a micromechanical approach. A Representative Volume Element (RVE) model with periodic boundary conditions is constructed using the ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...
