Boundary Reflections of Rolling Waves in Cubic Anisotropic Material
Frontiers in Mechanical Engineering, 2021 Rolling waves have unconventional circular polarizations enabled by the equal-speed propagation of longitudinal and transverse waves in elastic solids. They can transport non-paraxial intrinsic (i.e. spin) mechanical angular momentum in the media.

Reflected waves and quantum gravity
Physical Review D, 2023 In the context of canonical quantum gravity, we consider the effects of a non-standard expression for the gravitational wave function on the evolution of inflationary perturbations. Such an expression and its effects may be generated by a sudden variation in the (nearly constant) inflaton potential.

Journal of Marine Science and Engineering, 2022 The coastline of the Ca Mau and Kien Giang provinces in the Vietnamese Mekong Delta has been severely eroded in recent decades. Pile–Rock Breakwaters (PRBWs) are among the most widely adopted structures for controlling shoreline erosion in this region ...

Physical Experimental Study on the Wave Reflection and Run-Up of a New Ecological Hollow Cube
Journal of Marine Science and EngineeringImplementing quadrangular hollow blocks on breakwaters is a common method for wave mitigation and ocean disaster prevention. In order to improve the wave-damping performance of conventional quadrangular hollow blocks, a new quadrangular hollow block is ...

PLoS ONE, 2013 ObjectivesAugmentation index (AIx) is widely used as a measure of wave reflection. We compared the relationship between AIx and age, height and sex with 'gold standard' measures of wave reflection derived from measurements of pressure and flow to ...

Wave transmission and reflection of waves “The myth is in their use”
Artery Research, 2012 Arterial input impedance, as complete description of the arterial system, is explained by waves and wave reflection. Without wave reflections input impedance would equal aortic characteristic impedance and pressure and flow wave shapes would be similar.

Reflection of Strong Blast Waves [PDF]
The Physics of Fluids, 1964 The reflection of strong point-source blast waves is studied using the continuum concept of flow of ideal gases. Methods of obtaining the upper and lower bounds as well as a Taylor series expansion of the position of the reflected shock is considered. The procedure of studying the flow variables near the reflected shock is also described.

On the Reflection of a Spherical Sound Wave from a Finite Size Surface
Applied SciencesRoom acoustics computer models based on geometrical acoustics usually handle the sound reflections by the assumption of plane waves. However, if the sound source is a point source, which is usually the case, the spherical wave reflection would be more ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Super‐Refractory Status Epilepticus (SRSE) is a rare, life‐threatening neurological emergency with unclear etiology in many cases. Mitochondrial dysfunction, often due to disease‐causing genetic variants, is increasingly recognized as a cause, with each gene producing distinct pathophysiological mechanisms.
