Restoring Convergence Order in Explicit Runge-Kutta Integration of Hyperbolic PDE with Time-Dependent Boundary Conditions

This paper proposes a purely spatial remedy for order reduction in explicit Runge-Kutta integration of hyperbolic PDEs with time-dependent boundary conditions by redesigning boundary-adjacent derivative operators to satisfy tableau-dependent algebraic conditions, thereby recovering the nominal convergence order without altering the time integrator.

Emergent complexity and rhythms in evoked and spontaneous dynamics of human whole-brain models after tuning through analysis tools

This paper presents a framework integrating The Virtual Brain (TVB) and the Collaborative Brain Wave Analysis Pipeline (Cobrawap) to tune a human whole-brain model, demonstrating that the calibrated configuration successfully reproduces biologically realistic spontaneous and evoked dynamics, including complex rhythms and spatio-temporal patterns, which are absent in the default model.

Multi-Level Hybrid Monte Carlo / Deterministic Methods for Particle Transport Problems

This paper introduces multilevel hybrid transport (MLHT) methods that combine multilevel Monte Carlo techniques with quasidiffusion and second-moment deterministic approaches to efficiently solve the neutral-particle Boltzmann transport equation, demonstrating that variance reduction in correction factors outpaces the increasing computational cost of coarse-grid calculations.
