Further, a metal grating 15 with a width W2 and an interval S2 that are equivalent to the width of the IDTs 12 and 13 is formed between the IDTs 12 and 13 on an upper surface 14. The grating 15 traps acoustic t
Gravitational wave telescope place extremely high demands on structural thermal deformation, making material selection a critical issue. Carbon fiber reinforced polymer (CFRP) is an ideal choice for the support structure of telescope due to its low coefficient of thermal expansion (CTE) and designable ...
If eE/mωc≥1, which is equivalent to ωB≥ω, the magnitude of the transverse velocity reaches close to the speed of light in a time which is a fraction of the wave period. At this moment the Lorentz force on the charged particle due to the magnetic field of the light wave becomes...
PINNs take into account the underlying PDE, i.e. the physics of the problem, rather than attempting to deduce the solution based solely on data, i.e. by fitting a neural network to a set of state-value pairs. The idea of creating physics-informed learning machines that employ systematically...

Acute Transverse Myelitis After Spinal Anesthesia: Should Anesthesia be Condemned? Classifying the Forms of Trigeminal Neuralgia Clinical Impact of the Use of Biomarkers in the Diagnosis of Alzheimer’s Dementia Effects of Different Postures and Ankle Pump Movement on Venous Hemodynamics of Lower Limb Py...
Mass transport For progressive waves a net mass transport (drift) occurs between the wave trough and the wave crest (Eulerian definition). Under uniform conditions in the longshore direction the net cross-shore discharge must be zero. The mass flux is calculated from the applied wave theory. ...
The prediction of transverse depth distribution in alluvial channel bends has had considerable attention from river engineers, as it is essential in investigations of navigability improvement in river bends and in design of optimal channel bank protection. Since the pioneering work of van Bendegom (...
This is a study of proton transmission through planar channels of tungsten, where a proton beam is treated as an ensemble of noninteracting wave packets. For this system, the structural stability manifests in an appearance of caustic lines, and as an equivalence of self-interference produced wave...
transverse to the beam trajectory; selectively controlling the energy of the laser beam pulses; and delivering, during a primary laser pass along the beam trajectory, a laser beam pulse to the workpiece at each of a plurality of selective spot locations within the deflection range of the second...
