Dynamics of shallow impact cratering [PDF]

, 2005
We present data for the time-dependence of wooden spheres penetrating into a loose non-cohesive packing of glass beads. The stopping time is a factor of three longer than the time $d/v_\circ$ needed to travel the total penetration distance $d$ at the ...

Study on the mechanism of long-range hydrophobic force based on the cavitation of metastable liquid film

Acta Physica Sinica
Hydrophobic force, a key driving force in colloid physicochemical and biological macromolecular systems, exhibit a distinct multi-scale effect. The prevailing scholarly consensus attributes long-range hydrophobic forces to bubble bridging, facilitated by

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

FEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Study on softening characteristics of mudstones in shallow buried strata in Xinjiang and countermeasures for tunnel support

矿业科学学报, 2021
The Xinjiang water conveyance tunnel is a shallow buried mudstone stratum. After the water absorption, the strength of the surrounding rock softens and large deformation occurs.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...
