The behavior of surface horizontally polarized shear waves (SH waves) in the composite multi-material structure with a periodic irregular and interface is investigated analytically present study. To unravel enshrouded features SH-wave propagation multi-layer structure, we consider model three distinct materials. In schematic problem, guiding layer (M-I) contains fluid-saturated porous materials...

Objective Toexplore the correlation between blood pressure in the supine position and target organ damage in subjects over 60 years of age. Methods In 2444 individuals, we investigated the association of systolic blood pressure (SBP) in the supine position with the target organ damage indices microalbuminuria (ALBU), brachial-ankle pulse wave velocity (baPWV), and carotid intima-media thickness...

The unified theory for elastic wave propagation in polycrystalline materials, developed by Stanke and Kino [ J. Acoust. Soc. Am. 75, 665–681 (1984)], has been applied to compute the propagation constants in materials consisting of cubic crystallites with texture. The particular texture considered here is one in which one of the cube axes of each crystallite is aligned in a preferred direction w...

The problem of propagation of plane wave including body and surface waves propagating in a transversely isotropic half-space with a depth-wise axis of material symmetry is investigated in details. Using the advantage of representation of displacement fields in terms of two complete scalar potential functions, the coupled equations of motion are uncoupled and reduced to two independent equations...

Although the pairing mechanism of Fe-based superconductors (FeSCs) has not yet been settled with consensus with regard to the pairing symmetry and the superconducting (SC) gap function, the vast majority of experiments support the existence of spin-singlet sign-changing s-wave SC gaps on multi-bands ([Formula: see text]-wave state). This multi-band [Formula: see text]-wave state is a very uniqu...
