Shear Horizontal (SH) guided waves have been extensively used to estimate and detect defects in structures like plates pipes. Depending on the frequency plate thickness, more than one guided-wave mode propagates, which renders signal interpretation complicated due mixing complex behavior of each individual interacting with defects. This paper investigates use machine learning models analyse two...

The effect of viscous liquid loading on SH-SAW devices on AlN=sapphire structure has been experimentally investigated. The sensitivity of the devices to liquid (glycerol=water mixtures) viscosity changes is measured to be approximate 8.2 10 9 m s=kg, which is only about 30% of that of commonly used quartz Love wave devices. This indicates that, when used for mass sensing in liquid, the AlN SHSA...

OBJECTIVE Hypertension guidelines propose home (HBP) or ambulatory (ABP) blood pressure monitoring as indispensable after office measurement (OBP). However, whether preference should be given to HBP or ABP remains undetermined. DESIGN AND METHOD We recruited 831 consecutive patients (mean age, 50.6 years; 49.8% women) referred for ABP monitoring to our clinic, if they had never taken (∼90%) o...

The leading modes of variability of the extratropical circulation in both hemispheres are characterized by deep, zonally symmetric or ‘‘annular’’ structures, with geopotential height perturbations of opposing signs in the polar cap region and in the surrounding zonal ring centered near 458 latitude. The structure and dynamics of the Southern Hemisphere (SH) annular mode have been extensively do...

In-liquid wave attenuation is the major factor that limits resolution of acoustic biosensors. Existing devices rely on shear mode operation to reduce mechanical motion transferred liquid. However, energy leakage still exists through radiation. In this article, we combined phononic metasurface based local resonators with horizontal surface (SH-SAW) address above issue. The shear-horizontal (SH-P...

Abstract. A major strong sudden stratospheric warming (SSW) occurred in the Southern Hemisphere (SH) stratosphere 2002 (hereafter referred to as SSW2002), which is one of most unusual winters SH. Following several warmings, polar vortex broke down midwinter. Eastward-traveling waves and their interaction with quasi-stationary planetary played an important role during this event. This study anal...

The cyclic-tension fatigue in a rolled thin-plate of aluminum alloy Al–4Cu–1Mg was evaluated nondestructively using a horizontally polarized shear wave (SH) transmission method under optimized measuring and analyzing conditions. The propagation time of the SH waves, which contained elements of reflected waves, had three distinct stages, the first, middle and final ones, during the fatigue proce...

Cell separation techniques are used widely in immunology studies. The one-step antigen-specific separation technique on a microfluidic platform based on shear horizontal surface acoustic wave (SH-SAW) sensors. With the specific antibodies conjugated onto the surface of the SH-SAW sensors could be used to specifically recognize the specific cells in the clinical body fluids. The cell isolation a...
