Influence of laser spot size at diffuser plane on the longitudinal spatial coherence function of optical coherence microscopy system

open access: yes, 2019
Coherence properties and wavelength of light sources are indispensable for optical coherence microscopy/tomography as they greatly influence the signal to noise ratio, axial resolution, and penetration depth of the system.

Goldbach-Linnik type problems involving one prime, four prime cubes and powers of 2

open access: yes, 2023
In this paper, we prove that every pair of sufficiently large odd integers can be represented in the form of a pair of one prime, four prime cubes and $48$ powers of $2$.

A Data‐Driven Simplified Nernst Equation for Estimating Reduction Potentials in Groundwater from pH and Temperature

open access: yesGroundwater, Volume 63, Issue 5, Page 725-735, September/October 2025.
A data‐driven simplified Nernst equation enables rapid estimation of reduction potentials in groundwater using only pH and temperature. This approach reduces computational complexity while preserving accuracy, supporting scalable redox assessments across aquifers and enhancing biogeochemical modeling in data‐limited or large‐scale hydrogeological ...

On Convergence to Equilibrium Distribution, I. The Klein - Gordon Equation with Mixing

open access: yes, 2002
Consider the Klein-Gordon equation (KGE) in $\R^n$, $n\ge 2$, with constant or variable coefficients. We study the distribution $\mu_t$ of the random solution at time $t\in\R$.

Smallest totient in a residue class

open access: yesBulletin of the London Mathematical Society, Volume 57, Issue 6, Page 1908-1917, June 2025.
Abstract We obtain a totient analogue for Linnik's theorem in arithmetic progressions. Specifically, for any coprime pair of positive integers (m,a)$(m,a)$ such that m$m$ is odd, there exists n⩽m2+o(1)$n\leqslant m^{2+o(1)}$ such that φ(n)≡a(modm)$\varphi (n)\equiv a\ (\mathrm{mod}\ m)$.
