Characterizing Inner Pressure and Stiffness of Trophoblast and Inner Cell Mass of Blastocysts. [PDF]

Biophys J, 2018
It has long been recognized that mechanical forces underlie mammalian embryonic shape changes. Before gastrulation, the blastocyst embryo undergoes significant shape changes, namely, the blastocyst cavity emerges and expands, and the inner cell mass (ICM) forms and changes in shape.

Plantar pressure gradient and pressure gradient angle are affected by inner pressure of air insole. [PDF]

Front Bioeng Biotechnol
Clinically, air insoles may be applied to shoes to decrease plantar pressure gradient (PPG) and increase plantar gradient angle (PGA) to reduce foot ulcers. PPG and PGA may cause skin breakdown. The effects of different inner pressures of inflatable air insoles on dynamic PPG and PGA distributions are largely unknown in non-diabetics and people with ...

On the Inner Topological Pressure within the Topological Insulators [PDF]

Annalen der Physik, 2021
AbstractTopological insulators (TIs) have axion electrodynamics instead of the usual Maxwell. Then, there is an additional energy density, whose origin is topological, generating a pressure that is found analytically. It is shown that the topological electric and magnetic fields act only on the surface, while the scalar axion does as a real Klein ...

Equilibrium of Inner and Middle Ear Pressure

Acta Oto-Laryngologica, 1993
Global balance of inner and middle ear pressure is controlled by the cerebrospinal fluid inside and the atmospheric pressure outside. The cochlear and vestibular aqueducts and the Eustachian tube, connected by a one-way communication, provide a fine control over inner and middle ear pressure.

Thermal-hydraulic characteristics in inner and outer wire-wrapped for a fast reactor annular fuel assembly

Frontiers in Energy Research, 2022
The annular fuel has dual-cooled surfaces internally and externally. Compared with traditional cylindrical fuel, the inner flow field is introduced on the annular fuel assembly, and wire-wrapped can influence the inner flow field.
