The importance of mean free path in determining gas flow behaviour [PDF]

open access: yes, 2010
We investigate whether a power-law form of probability distribution function better describes the free paths of dilute gas molecules in a confined system.

Constitutive modeling of Ti-2.7Cu alloy based on strain compensation and PSO-BP neural network

open access: yesCailiao gongcheng, 2019
The isothermal compression tests of Ti-2.7Cu alloy were tested to study the hot deformation behavior in temperature range of 740-890℃ and strain rate range of 0.001-10s-1 on a Gleeble-3500 thermomechanical simulator.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

A Constitutive Equation for High Temperature Flow [PDF]

open access: yes, 1975
A constitutive equation which describes the behavior of strain rate sensitive materials which do not strain harden significantly is often required in the solution of various problems involving metal flow.

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.

Modified constitutive equation by using phase field simulation of dynamic recrystallization in friction stir welding

open access: yesJournal of Materials Research and Technology, 2021
The application of appropriate constitutive equation describing the relationship between the flow stress, temperature and strain rate is essential to get deep insight into the process mechanism of friction stir welding (FSW).

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 ...

On dilatational plastic constitutive equation of ductile materials and plastic loading paths at bifurcation [PDF]

open access: yes, 1991
The dilatational plastic constitutive equation presented in this paper is proved to be in a form of generality. Based on this equation, the constitutive behaviour of materials at the moment of bifurcation is demonstrated to follow a loading path with ...

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

open access: yesFEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

Improvement of Analytical Model for Oblique Cutting—Part I: Identification of Mechanical Characteristics of Machined Material

open access: yesMetals, 2023
Analytical cutting models have recently become quite widespread due to the simplicity and rapidity of calculations as well as the stability of the solutions.
