Reducing stress concentration factor around a hole on a plate by piezoelectric patch [PDF]

open access: yesInternational Journal of Advanced Design and Manufacturing Technology, 2013
Using piezoelectric patches the stress concentration around a hole on a plate under tension is reduced and controlled. To attain the reduction in stress two placements for piezoelectric patches is investigated.

Model tests on bearing characteristics of pile foundation in expansive soil foundation under vertical loadings

open access: yesYantu gongcheng xuebao, 2019
Based on the self-developed multi-directional load system for piles a series of model tests are carried out to study the behaviors of compressive and uplift loaded piles in expansive soils with two states of optimal water content and full saturation. The

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Analysis of Interference Factors for TLP Riser System

open access: yesShiyou jixie, 2016
Interference may occur between serial risers since the TLP riser system is under complex forces.The interference factors mainly include riser spacing,platform offset,top tension,wave and current.Determining how such factors interfere the risers helps to ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS 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 ...

A Method of Top Tension Optimization of Drilling Riser-conductor System

open access: yesShiyou jixie, 2015
With the exploration of deep water towards ultradeep water,the harsh marine environment could lead to riser-conductor stability issues like buckling and alternating stress failure.The effective axial stress equation of the whole riser-conductor system ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS 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.

Postoperative outcome is affected by an intraoperative combination of each graft tension change pattern in a double-bundle anterior cruciate ligament reconstruction

open access: yesAsia-Pacific Journal of Sports Medicine, Arthroscopy, Rehabilitation and Technology, 2016
Background: The purpose of this study is to evaluate the intraoperative tension change pattern of each anteromedial (AM) graft and posterolateral (PL) graft and to investigate the optimal femoral tunnel position in double bundle (DB) anterior cruciate ...
