Copula‐based joint modelling of emergency department visits with time‐varying dependence
Abstract Jointly modelling multiple correlated count time series is essential in health services research, where outcomes like emergency visits for mental health and substance use often evolve together. Ignoring these dependencies can obscure meaningful trends and limit the effectiveness of policy evaluation.

Riemann Problem for a limiting system in elastodynamics
This article concerns the resolution of the Riemann problem for a 2x2 system in nonconservative form exhibiting parabolic degeneracy. The system can be perceived as the limiting equation (depending on a parameter tending to 0) of a 2x2 strictly ...

The SIR Model in a Moving Population: Propagation of Infection and Herd Immunity
ABSTRACT In a collection of particles performing independent random walks on Zd$\mathbb {Z}^d$ we study the spread of an infection with SIR dynamics. Susceptible particles become infected when they meet an infected particle. Infected particles heal and are removed at rate ν$\nu$.

Singular solutions for 2x2 systems in nonconservative form with incomplete set of eigenvectors
In this article, we study the initial-value problem for two first-order systems in non-conservative form. The first system arises in elastodynamics and belongs to the class of strictly hyperbolic, genuinely nonlinear systems.

ABSTRACT This study provides exploratory evidence on whether going public may act as a catalyst for corporate sustainability and examines whether board‐level governance arrangements shape post‐IPO sustainability trajectories. Drawing on a formal conceptual framework that integrates agency theory, legitimacy theory, and the resource‐based view as ...

Photothermal bubble: Dynamics, manipulation, and applications
As a versatile platform for bubble manipulation, photothermal techniques empower diverse operations: planar translation by scanning the laser spot, sustained periodic bouncing from competing thermal and hydrodynamic flows, and even guided 3D trajectories achieved by tailoring the heating configuration.
