Scalable Atomistic Simulations of Quantum Electron Transport using Empirical Pseudopotentials

open access: yes, 2019
The simulation of charge transport in ultra-scaled electronic devices requires the knowledge of the atomic configuration and the associated potential. Such "atomistic" device simulation is most commonly handled using a tight-binding approach based on a ...

The averaging of nonlocal Hamiltonian structures in Whitham′s method

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 30, Issue 7, Page 399-434, 2002., 2002
We consider the m‐phase Whitham′s averaging method and propose the procedure of “averaging” nonlocal Hamiltonian structures. The procedure is based on the existence of a sufficient number of local‐commuting integrals of the system and gives the Poisson bracket of Ferapontov type for Whitham′s system.

Air pollution and greenness independently and interactively influence bird communities in an urban neighborhood

open access: yesConservation Science and Practice, Volume 7, Issue 10, October 2025.
In this study, we examined relationships between bird community metrics and environmental measures related to vegetation and air pollution within a residential neighborhood at multiple spatial scales. Greenness and air pollution measures independently and interactively influenced the bird community metrics we evaluated.
