Geometrical quadrupolar frustration in DyB$_4$ [PDF]

, 2005
Physical properties of DyB$_4$ have been studied by magnetization, specific heat, and ultrasonic measurements. The magnetic entropy change and the ultrasonic properties in the intermediate phase II indicate that the degeneracy of internal degrees of ...

Sonographic features of agenesis of dorsal pancreas

Indian Journal of Radiology and Imaging, 2013
Agenesis of dorsal pancreas is an extremely rare congenital anomaly that occurs due to failure of the dorsal pancreatic bud to form the body and tail of the pancreas. We report the sonographic appearance of this condition in six cases.

Operating limits for acoustic measurement of rolling bearing oil film thickness [PDF]

, 2003
An ultrasonic pulse striking a thin layer of liquid trapped between solid bodies will be partially reflected. The proportion reflected is a function of the layer stiffness, which in turn depends on the film thickness and its bulk modulus.

Ultra-broad low-frequency forbidden bands in 1D solid–fluid acoustic superlattices with multiple solid constituents

AIP Advances, 2023
In this paper, a theoretical model of underwater acoustic wave propagation, based on the transfer matrix method, is employed to calculate acoustic wave transmission through a 1D solid–fluid superlattice (SFSL) with multiple solid constituents.

Sound touch elastography of Achilles tendons in patients with type 2 diabetes mellitus versus healthy adults

Diabetology & Metabolic Syndrome, 2023
Background The studies of the effect of diabetes on the stiffness of Achilles tendon (AT) tissue remain inconclusive, we believe it is necessary to find a reliable method which can be used to detect the stiffness changes of the AT in the diabetic state ...
