A Dual‐Frequency Sensitivity Model for Optical Fibre Ultrasonic Sensors in Power Transformer Partial Discharge Detection

High Voltage, EarlyView.
ABSTRACT The detection of partial discharges (PD) on the power transformer tank demands higher sensitivity in ultrasonic detection. To target the detection frequency band for sensor optimisation and enhance sensitivity, this paper presents a dual‐frequency sensitivity model for optical fibre ultrasonic sensors.

Thermal electron-hydrogen laser assisted three-body scattering dynamics

Physics Open
Laser-assisted scattering (LAS) refers to the interaction of particles, such as electrons and atoms, in the presence of an external laser field. This process is vital in fields like radiation-matter interaction, plasma physics, laser cooling, medical ...

The Meijer transformation of generalized functions

International Journal of Mathematics and Mathematical Sciences, 1987
This paper extends the Meijer transformation, Mμ, given by (Mμf)(p)=2pΓ(1+μ)∫0∞f(t)(pt)μ/2Kμ(2pt)dt, where f belongs to an appropriate function space, μ ϵ (−1,∞) and Kμ is the modified Bessel function of third kind of order μ, to certain generalized ...

A computational approach for the unsteady flow of maxwell fluid with Caputo fractional derivatives

Alexandria Engineering Journal, 2018
In this paper, the velocity field and the time dependent shear stress of Maxwell fluid with Caputo fractional derivatives in an infinite long circular cylinder of radius R is discussed. The motion in the fluid is produced by the circular cylinder.

Zebrafish models of developmental epileptic encephalopathy accurately reflect clinical electrographic biomarkers

Epilepsia, EarlyView.
Abstract Objective Developmental epileptic encephalopathies (DEEs) are epilepsy conditions characterized by significant severity and treatment challenges. Spectral components of the encephalogram (EEG) may provide a valuable biomarker of epileptic severity.

Revisiting PSF models: Unifying framework and high‐performance implementation

Journal of Microscopy, EarlyView.
Abstract Localisation microscopy often relies on detailed models of point‐spread functions. For applications such as deconvolution or PSF engineering, accurate models for light propagation in imaging systems with a high numerical aperture are required. Different models have been proposed based on 2D Fourier transforms or 1D Bessel integrals.

Deciphering pro‐arrhythmogenic mechanisms of EPAC in human atrial cardiomyocytes

The Journal of Physiology, EarlyView.
Abstract figure legend This study aimed to investigate the effect of exchange proteins directly activated by cAMP (EPAC) on the regulation of human atrial cardiomyocyte electrophysiology and their potential involvement in the onset of atrial fibrillation (AF).

Myosin 7a is required for maintaining the transducing stereocilia and for force transmission to the MET channel during cochlear hair cell development

The Journal of Physiology, EarlyView.
Abstract figure legend Developmental changes in the hair‐bundle structure of outer hair cells (OHCs) and inner hair cells (IHCs) were examined in control and shaker‐1 mutant (Myo7aSh1/Sh1) mice, which carry a spontaneous missense mutation in the Myo7a gene that produces a non‐functional MYO7A protein.

A Bayesian Spatiotemporal Functional Model for Data With Block Structure and Repeated Measures

Environmetrics, Volume 37, Issue 2, March 2026.
ABSTRACT The analysis of spatiotemporal data is fundamental across multiple scientific disciplines, particularly in assessing the behavior of climate effects over space and time. A key challenge in this area is effectively capturing recurring climate phenomena, such as El Niño/La Niña (ENSO) phases, which induce prolonged periods of similar weather ...

Functional inequalities involving Bessel and modified Bessel functions of the first kind

Expositiones Mathematicae, 2008
Since the sine and cosine functions and the hyperbolic sine and cosine functions are particular cases of Bessel and modifed Bessel functions, the author extends the inequality \(\cosh x-1\), where \(\Gamma\) is Euler gamma function and \(I_{p}(x)\) is the modified Bessel function of first kind. Some properties and inequalities satisfied by \(G_{p}(x)\)
