AAA+ protein unfoldases—the Moirai of the proteome

FEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Experimental research on influences of suction on deformation characteristics of loess under unloading-reloading conditions

Yantu gongcheng xuebao, 2017
In order to explore the influences of matrix suction and net confining pressure on the deformation-strength and unloading-reloading modulus of loess, three groups of 27 tests are performed using the unsaturated triaxial apparatus for undisturbed Q3 loess

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Dissipated energy in undrained cyclic triaxial tests [PDF]

, 2015
Energy-based methods are an emerging tool for the evaluation of liquefaction potential. These methods relate excess pore water pressure build-up to seismic energy dissipated per unit volume.

Thermofield Dynamics and Casimir Effect for Fermions

, 2004
A generalization of the Bogoliubov transformation is developed to describe a space compactified fermionic field. The method is the fermionic counterpart of the formalism introduced earlier for bosons (J. C. da Silva, A. Matos Neto, F. C. Khanna and A. E.

Experimental Study on Radial Cementation Strength of the First Cementing Interface in HTHP Wells

Shiyou jixie, 2021
In view of the stress status of cement ring in high-temperature and high-temperature(HTHP)wells, a set of full-size HTHP cement ring sealing integrity evaluation test equipment was developed. The influence of confining pressure and casing pressure on the
