Closed Hypersurfaces Driven by Mean Curvature and Inner Pressure [PDF]

Communications on Pure and Applied Mathematics, 2012
AbstractWe introduce a hyperbolic equation that describes the motion of closed hypersurfaces in a Riemannian manifold with surface tension and inner pressure as driving forces. In the case of spherical surfaces this equation can be considered as an idealized mathematical model for a moving soap bubble.

Lamellar projections in the endolymphatic sac act as a relief valve to regulate inner ear pressure

eLife, 2018
The inner ear is a fluid-filled closed-epithelial structure whose function requires maintenance of an internal hydrostatic pressure and fluid composition.

Sound velocity of hexagonal close-packed iron to the Earth’s inner core pressure

Nature Communications, 2022
Here we determine the compressional and shear wave velocities (vp and vs) of hexagonal close-packed iron, a candidate for the main constituent of the Earth’s inner core, to pressures above 300 gigapascals using a newly designed diamond anvil cell and ...

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.

Hydrostatic Pressure Modulates Intervertebral Disc Cell Survival and Extracellular Matrix Homeostasis via Regulating Hippo-YAP/TAZ Pathway

Stem Cells International, 2021
Established studies proved that hydrostatic pressure had multiple effects on the biological behavior of the intervertebral disc (IVD). However, the conclusions of the previous studies were inconsistent, due to the difference in hydrostatic loading ...

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.

Deformation characteristic of the axially fiber reinforced cylindrical rubber subjected to inner pressure

Nihon Kikai Gakkai ronbunshu, 2018
The cylindrical rubber is axially reinforced by the fiber and closed by the rigid ends. When the inner pressure is applied to this fiber reinforced rubber cylinder, the diameter expands and the length shrinks.

Pressure-driven wrinkling of soft inner-lined tubes

New Journal of Physics, 2022
A simple equation modelling an inextensible elastic lining of an inner-lined tube subject to an imposed pressure difference is derived from a consideration of the idealised elastic properties of the lining and the pressure and soft-substrate forces.
