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

International 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.

A new goodness‐of‐fit measure for probit models: Surrogate R2

British Journal of Mathematical and Statistical Psychology, Volume 76, Issue 1, Page 192-210, February 2023., 2023
Abstract Probit models are used extensively for inferential purposes in the social sciences as discrete data are prevalent in a vast body of social studies. Among many accompanying model inference problems, a critical question remains unsettled: how to develop a goodness‐of‐fit measure that resembles the ordinary least square (OLS) R2 used for linear ...

On covering theory and its applications [PDF]

arXiv
The aim of this survey is to present applications of covering techniques in the theory of Krull-Gabriel dimension. We start with recalling fundamental facts of the classical covering theory of quivers and locally bounded categories. Then we present some recent results on covering theory of functor categories.

Implicit Central Difference Approximations of Averaged Dynamics of Highly Oscillatory Systems With Applications to Direct Optimal Control

Optimal Control Applications and Methods, EarlyView.
Trajectory optimization of highly oscillatory systems can require huge computational efforts if the horizon of the problem is much larger than the duration of a single cycle. To alleviate this effort, stroboscopic averaging methods can be used, which utilize local single‐cycle simulations of the oscillatory dynamics, to then approximate and integrate ...

Weathering the Storm: What Did It Take for Pennsylvania Economic Development Organizations to Overcome the COVID‐19 Pandemic?

Public Administration and Development, EarlyView.
ABSTRACT The COVID‐19 pandemic had profound impacts that significantly rippled through economies, vulnerable communities, and nations globally. In this study, we aim to investigate what combination of network‐level factors, network and organizational social capital, and other organizational factors helped Economic Development Organizations (EDOs) in ...

The Serial Effects of Callous‐Unemotional Traits and Gray Matter Density in the Right Dorsomedial Prefrontal Cortex on Social Desirability

PsyCh Journal, EarlyView.
ABSTRACT Social desirability affects several aspects of human life. However, the neuropsychological mechanisms underlying individual differences in social desirability remain unclear. This study explored the neuroanatomical basis of individual differences in social desirability using regional gray matter density (rGMD) as a brain indicator in a sample ...
