Multivariate representations of univariate marked Hawkes processes

Scandinavian Journal of Statistics, Volume 53, Issue 1, Page 140-174, March 2026.
Abstract Univariate marked Hawkes processes are used to model a range of real‐world phenomena including earthquake aftershock sequences, contagious disease spread, content diffusion on social media platforms, and order book dynamics. This paper illustrates a fundamental connection between univariate marked Hawkes processes and multivariate Hawkes ...

From Sample to Mixed Reality: A Translational 3D MALDI Imaging Platform for Advanced 3D Spatial Omics Analysis of 3D Cell Culture Disease Models

Advanced Science, Volume 13, Issue 12, 27 February 2026.
A comprehensive technology platform enables high‐fidelity, volumetric MALDI imaging of 3D cell cultures by integrating custom embedding molds, a semi‐automated computational framework for 3D reconstruction, voxel‐instead of pixel‐based biomarker discovery, and immersive mixed reality data exploration.

Scale‐Invariant Waveguiding in Flatland

Exploration, Volume 6, Issue 1, February 2026.
The study introduces scale‐invariant metasurface waveguides with uniform modal field distribution and an effective index independent of the core width. By leveraging spatial symmetry and fine‐tuning mode profiles, the design is validated through near‐field measurements in the C band, offering potential applications in flat optics, sensing, and ...

Dual integral equations with Fox's H-function kernel

International Journal of Mathematics and Mathematical Sciences, 1984
The dual integral equations involving Bessel function kernels were first considered by Weber in 1873. The problem comprised of finding potential of an electrified disc which belongs to a general category of mixed boundary value problems.

Solutions of a quadratic Volterra–Stieltjes integral equation in the class of functions converging at infinity

Electronic Journal of Qualitative Theory of Differential Equations, 2018
The paper deals with the study of the existence of solutions of a quadratic integral equation of Volterra–Stieltjes type. We are looking for solutions in the class of real functions continuous and bounded on the real half-axis $\mathbb{R}_+$ and ...

In Hyphomicrobium denitrificans Two Related Sulfane‐Sulfur Responsive Transcriptional Repressors Regulate Thiosulfate Oxidation and Have a Deep Impact on Nitrate Respiration and Anaerobic Biosyntheses

Molecular Microbiology, Volume 124, Issue 3, Page 204-220, September 2025.
In Hyphomicrobium denitrificans, the use of thiosulfate as a supplemental electron donor is regulated by two homologous sulfane‐sulfur responsive ArsR‐type transcriptional repressors, sHdrR and SoxR, that act cooperatively. Remarkably, the regulation by sHdrR/SoxR extends far beyond sulfur oxidation and deeply affects anaerobic metabolism, particularly

The Effect of the Wall Thickness of the Material Loaded Cavity On the RCS Reduction

Düzce Üniversitesi Bilim ve Teknoloji Dergisi
In this paper, the effect of a parallel plate waveguide's wall thickness on radar cross-section reduction (RCS) is rigorously analyzed for H-polarization by using the Wiener-Hopf Technique, when the waveguide region is loaded with dielectric material and

Rayleigh wave scattering at the foot of a mountain

International Journal of Mathematics and Mathematical Sciences, 1987
A theoretical study of scattering of seismic waves at the foot of a mountain is discussed here. A mountain of an arbitrary shape and of width a (0≤x≤a, z=0) in the surface of an elastic solid medium (z≥0) is hit by a Rayleigh wave. The method of solution

The Dynamics of Fast and Slow Earthquake Ruptures in Viscoelastic Materials

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract Classical theories using linear elasticity predict that crack propagation asymptotically approaches a limiting speed, beyond which the energy balance becomes unphysical. However, geophysical and laboratory observations show that ruptures can propagate at either a very low, stable speed or a significantly high speed.
