Efficient Frequency-Dependent Newmark-Beta-FDTD Method for Periodic Grating Calculation

IEEE Photonics Journal, 2016
In this paper, the Newmark-Beta algorithm is introduced into the finite-difference time-domain (FDTD) method in dispersion media, resulting in an unconditionally stable method for periodic metallic grating analysis.

From Selfhood to Social Solidarity; From a Mind towards the Collective Thinking and Working Bodies: A Marxist Approach

Scientia, 2022
What our minds and conceive, our bodies can achieve. I will argue that “the mind is not then an autonomous substance, capable of forming its own states without recourse to what lies beyond it: it states arrive by courtesy of a specific external ...

War and Revolution: Friedrich Engels as a Military and Political Thinker

War & Society, 2019
This article explores the link between political and military strategy and tactics in the work of Friedrich Engels. Though widely praised for his understanding of military affairs, Engels’ interlocutors have tended to be dismissive of his political works.

An Iterative Procedure for the Estimation of Drift and Diffusion Coefficients of Langevin Processes

, 2005
A general method is proposed which allows one to estimate drift and diffusion coefficients of a stochastic process governed by a Langevin equation. It extends a previously devised approach [R.
