Enhancing Efficiency in Multiscale Simulation: Comparing a Lagrange Multiplier Based Approach and a Weak Staggered Coupling With Optional SPML Interface for Wave Propagation

open access: yesInternational Journal for Numerical Methods in Engineering, EarlyView.
ABSTRACT The representation of material failure due to wave propagation is essential for the numerical analysis of engineering structures under high dynamic loading. Explicit time integration schemes are well established for this kind of application.

Irradiated Coherent States in Magnetoresistance of 2D Electron Systems

open access: yesphysica status solidi (b), EarlyView.
A theoretical approach on the microwave‐induced resistance oscillations based on the coherent states of the quantum harmonic oscillator is reported. The coherent state expression for the quantum oscillator under a time‐dependent force is calculated. It is found that the principle of minimum uncertainty of coherent states, involving time and energy, is ...

Building and testing necessity theories in supply chain management

open access: yesJournal of Supply Chain Management, Volume 59, Issue 1, Page 48-65, January 2023., 2023
Abstract This article contributes to the Emerging Discourse Incubator initiative by presenting how supply chain management scholars can contribute to theory development by means of necessity theories. These are unique theories that inform what level of a concept must be present to achieve a desired level of the outcome.

Data assimilation errors due to incomplete accounting of balanced versus unbalanced moisture

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We investigate data assimilation strategies with moisture and assess the impact of accounting for moisture's balanced and unbalanced components. To illustrate the main ideas, examples are presented using a simple model consisting of linear, moist, shallow‐water equations with stochastic forcing.

A Short Note On M-Symmetric Hyperelliptic Riemann Surfaces

open access: yesCubo, 2010
We provide an argument, based on Schottky groups, of a result due to B. Maskit which states a necessary and sufficient condition for the double oriented cover of a planar compact Klein surface of algebraic genus at least two to be a hyperelliptic Riemann
