Application of Mudline Tubing Hanger in Dry Tree Well on TLP Platform

open access: yesShiyou jixie, 2018
Reducing the tension of the TTR riser of the TLP platform could help to reduce the platform load and size. The overall and local tension force analyses of the TTR system indicate that the gravity of the TTR riser does not affect the top tension of the ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Tension and compression behaviors of Moso bamboo (Phyllostachys pubescens) for structural use

open access: yesCase Studies in Construction Materials
Moso bamboo exhibits strong mechanical properties and demonstrates high economic efficiency. However, the limited availability of mechanical data and lack of clarity regarding the failure mechanism hinders its application in architecture.

Optimal Top Tension for Deep Water Testing String

open access: yesDEStech Transactions on Engineering and Technology Research, 2017
The tension exerted on testing string through platform tensioning system is an important parameter during testing a deep water oil well. Based on testing technological procedure, a practical method was established to find the minimum tension load on the precondition that string effective axial force would remain positive throughout the operation ...

Damage Diagnosis of Top Tensioned Riser Based on Strain Response

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
Abstract Strain has a high sensitivity to structural damage and can be used for damage diagnosis of marine risers in engineering. Considering the structure and boundary conditions of the top tensioned riser, it can be simplified to the Euler-Bernoulli beam element, and the strain equation on the riser wall is derived.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Self-Tensioning Feature of Knotless Suture Anchor Provides Reproducible Knotless Fixation Independent of Initial Tension

open access: yesOrthopaedic Journal of Sports Medicine, 2021
Background: Anterior cruciate ligament (ACL) reconstruction with suture tape reinforcement has been shown to biomechanically reduce elongation and increase ultimate strength.

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

open access: yesFEBS 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 ...
