Experimental Study on Cyclic Shear Performance of the Four-Way Geogrid Reinforcement–Soil Interface
Applied SciencesThis paper presents the results of horizontal cyclic direct shear tests at the reinforced soil interface of a four-way polypropylene geogrid reinforced sandy soil. The influence of normal stress and shear displacement amplitude on the shear stress, shear

Temporal variation of shear-wave splitting parameters before and after the 2008 Movri Mountain earthquake in northwest Peloponnese (Greece) [PDF]
, 2013 On June 8, 2008, at 12:25 GMT, a Mw 6.4 earthquake, the Movri Mountain earthquake, occurred in the area of northwest Peloponnese, western Greece. The epicenter was located in the municipality of Movri, 35 km southwest of Patras. For this study, a crustal

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Effects of Groove Feature on Shear Behavior of Steel-Sand Interface
Advances in Civil Engineering, 2020 Surface groove morphology of structure and particle distribution of soil had a significant effect on the surface friction of structure. In order to investigate the interface shear stress-shear displacement curves, interface model and interface shear ...

Shear Banding in Time-Dependent Flows of Complex Fluids [PDF]
, 2013 We explore theoretically the time-dependent rheological response of complex fluids to step stress, shear startup and strain ramp deformations. We study soft glassy materials and entangled polymeric materials above and below the glass transition using the

Observations of stress relaxation before earthquakes [PDF]
, 2004 Theory and observations suggest that seismic shear wave splitting, caused by fluid-saturated stress-aligned microcracks, directly monitors low-level deformation before fracturing, faulting and earthquakes occur.

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells
Molecular Oncology, EarlyView.This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

A machine learning-based method for predicting the shear behaviors of rock joints
Soils and FoundationsIn this study, machine learning prediction models (MLPMs), including artificial neural network (ANN), support vector regression (SVR), K-nearest neighbors (KNN), and random forest (RF) algorithms, were developed to predict the peak shear stress values ...

FEBS Open Bio, EarlyView.The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.
