Thermoelasticity of Hexagonal Close-Packed Iron from the Phonon Density of States [PDF]
, 2012 Iron is the main constituent in Earth’s core, along with ~5 to 10 wt% Ni and some light elements (e.g., H, C, O, Si, S). This thesis explores the vibrational thermodynamic and thermoelastic properties of pure hexagonal close-packed iron (ε-Fe), in an ...

Repulsion of the Futsal Ball Depending on the Pressure in it [PDF]
Sport Mont, 2018 The aim of this research is to determine the elastic (repulsive) properties of the futsal ball depending on the air pressure in it. Futsal ball of standard dimensions was released on the fl at solid surface from the height of nine meters for four times.

Distinct layering in the hemispherical seismic velocity structure of Earth's upper inner core [PDF]
The existence of hemispherical variation in the Earth's inner core is well-documented, but consensus has not yet been reached on its detailed structure. The uppermost layers are a region of particular importance, as they are directly linked to the growth

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.

Tunable adhesion of an elastic pillar by pressurizing inner cavity
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2021 This work studies the effect of a cavity with inner pressure on the adhesion of circular pillars with a flat tip in contact with a rigid smooth surface. The inner cavity of pillars is pressurized positively before the contact. The effect of the cavity on the adhesion is examined for different cavity diameters and different membrane thicknesses over the

FEBS 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 ...

Fluid-solid coupling model and biological features of large vestibular aqueduct syndrome
Frontiers in Bioengineering and Biotechnology, 2023 Objective: Computed tomography (CT) images of the temporal bone of large vestibular aqueduct syndrome (LVAS) patients were used to establish 3D numerical models based on the structure of the inner ear, which are, in turn, used to construct inner ear ...
