Rayleigh-wave frequency discriminator
Electronics Letters, 1972 A frequency discriminator using two Rayleigh-wave filters and two rectifying networks is described. For each filter, one of the transducers has a finger length varying according to a (sin x/x)2 law, so that the frequency response is almost triangular. The central frequencies of the two filters are different.

Rhythms in longitudinal thalamic recordings are linked to seizure risk
Epilepsia, EarlyView.Abstract Objective Seizure unpredictability remains a major clinical challenge for people with epilepsy. Previous works have shown that seizure risk is associated with circadian and multi‐day cycles in both brain and physiological signals. However, it remains unclear whether neural activity from deep brain structures such as the anterior nucleus of the

Short Note: The ellipticity of Rayleigh waves at infinite depth [PDF]
Geofísica Internacional, 2008 I present an analytical formula and an approximation for the ellipticity of Rayleigh waves in a homogeneous half-space at infinite depth in terms of Poisson’s ratio. The result is compared with the corresponding formulas for surface ellipticity.

Detection of standing internal gravity waves in experiments with convection over a wavy heated wall
, 2020 Convection over a wavy heated bottom wall in the air flow has been studied in experiments with the Rayleigh number $\sim 10^8$. It is shown that the mean temperature gradient in the flow core inside a large-scale circulation is directed upward, that ...

Attenuated leaky Rayleigh waves [PDF]
The Journal of the Acoustical Society of America, 1993 The propagation of leaky Rayleigh waves under the influence of viscous damping and heat conduction in boundary layers is studied using the matched asymptotic method. Viscosity of the fluid is considered unimportant except in a thin viscous boundary layer at the interface.

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review
Heat Transfer, EarlyView.ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

Optical Kerr Gating as a Strategy for Noise Reduction in Femtosecond Stimulated Raman Spectroscopy
Journal of Raman Spectroscopy, EarlyView.We report an experimental approach, where an Optical Kerr gate is incorporated with Femtosecond Stimulated Raman Spectrometry (FSRS). The gate functions as a temporal filter that preferentially suppresses the FSRS inherent background. FSRS spectra are reported with the Kerr‐gated methodology with significantly improved SNR compared to the conventional ...
