Steady rimming flows with surface tension [PDF]

open access: yes, 2008
We examine steady flows of a thin film of viscous fluid on the inside of a cylinder with horizontal axis, rotating about this axis. If the amount of fluid in the cylinder is sufficiently small, all of it is entrained by rotation and the film is ...

Simulation of wavy wrinkling of web caused by roller tilt (Change of the number of wrinkles and causes of the onset of the wrinkling)

open access: yesNihon Kikai Gakkai ronbunshu, 2018
This paper deals with the onset and development of wavy wrinkling of a web caused by a roller tilt using a FEM commercial software. The simulation model mainly used is composed of two rigid rollers and a web (a rectangular sheet) divided by a membrane ...

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.

Measurement of Interfacial Tension between Polymer Melts: Improved Imbedded Fiber Retraction, Breaking Thread and Dynamic Viscoelasticity Methods [PDF]

open access: yes, 1999
We improved the imbedded fiber retraction (IFR) method as a simple method to obtain the interfacial tension between polymer melts. A force balance equation for a fiber in an immiscible matrix by Cohen and Carriere is solved for a more realistic fiber ...

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 ...

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Effect of Initial Curvature on Pipeline Bearing Capacity

open access: yesShiyou jixie, 2020
To study the influence of the initial curvature on the bearing capacity of the pipeline,a mathematical relationship between the strain energy and deformation of the cross section of the pipeline is established based on the beam theory.
