Proceedings of the American Mathematical Society, 1963 We propose to call O2n(V) the Rayleigh function of order 2n. The Rayleigh functions of odd orders are identically zero. These functions were first used by Euler to determine the three smallest zeros of J0(2 Vz); and Rayleigh, independently, calculated the smallest positive zero of J,(z) with the aid of these functions.

Granular Rayleigh-Taylor Instability [PDF]
, 2009 A granular instability driven by gravity is studied experimentally and numerically. The instability arises as grains fall in a closed Hele-Shaw cell where a layer of dense granular material is positioned above a layer of air. The initially flat front defined by the grains subsequently develops into a pattern of falling granu-lar fingers separated by ...

Magnetic Control of Chiral Hybridized Phonon Magnetic Moments in Ferrimagnets Fe2‐xZnxMo3O8
Advanced Functional Materials, EarlyView.Helicity‐resolved magneto‐Raman spectroscopy reveals magnetic control of chiral phonon magnetic moments in polar ferrimagnet (ZnxFe2−xMo3O₈). Large spontaneous zero‐field phonon splittings, selective phonon–magnon coupling, and asymmetric Zeeman responses demonstrate that phonon chirality is governed by magnon‐phonon coupling and magnetization.

Application of extended Rayleigh damping model to 3D frame analysis
Japan Architectural Review, 2023 Rayleigh damping is commonly used in response history analysis (RHA) to provide an energy dissipation source, but the adaptation may be difficult if frequency independence damping is desired over a wide frequency range.

Global algebraic Poincaré–Bendixson annulus for the Rayleigh equation
Electronic Journal of Qualitative Theory of Differential Equations, 2023 We consider the Rayleigh equation $\ddot{x} + \lambda (\dot{x}^2/3-1)\dot{x} +x=0$ depending on the real parameter $\lambda$ and construct a Poincaré–Bendixson annulus $\mathcal{A}_\lambda$ in the phase plane containing the unique limit cycle $\Gamma_ ...

Advanced Functional Materials, EarlyView.Ferroelectricity in thin HfO2‐based films offers great possibilities for next‐generation neuromorphic memory devices. There, the response to subcoercive voltage signals is driven by the movement of mobile interfaces and their interaction with crystal defects – a yet rather unexplored aspect, which we shed light on and gain new insights into the complex

Fault-tolerant and finite-error localization for point emitters within the diffraction limit
, 2016 We implement an estimator for determining the separation between two incoherent point sources. This estimator relies on image inversion interferometry and when used with the appropriate data analytics, it yields an estimate of the separation with finite ...

Proceedings of the American Mathematical Society, 1964 where [x] denotes the greatest integer ,x. Rayleigh functions and polynomials of odd orders are identically zero. The function a2n(v) has been the subject of a number of investigations [3, p. 502]. Properties of 022n(v) have been discussed in a previous paper [ii. The object of the present paper is to discuss properties of the polynomial +2X(v).

Shaping Ti3C2 MXene Nanospheres for Precision Near‐Infrared Photothermal Therapy
Advanced Functional Materials, EarlyView.In this study, we report producing spherical MXenes via fs laser fragmentation of Ti3C2 flakes in liquid medium. The nanoparticles demonstrated pronounced light absorption and high photothermal conversion efficiencies of 68% and 63% under heating with NIR‐I and NIR‐II lasers, respectively.
