Modeling potential impact of COVID-19 pandemic on global electric vehicle supply chain

open access: yesiScience, 2022
Summary: The on-going COVID-19 pandemic and consequent lockdowns cast significant impacts on global economy in the short run. Their impact on stability of global electric vehicles (EVs) supply chain and thus our climate ambition in the long run, however,

Flex-route demand response transit scheduling based on station optimization

open access: yesShenzhen Daxue xuebao. Ligong ban, 2022
In order to increase the proportion of passengers served by the flex-route demand response transit (DRT) and reduce its service cost, we propose an improved D-k-means clustering algorithm that based on DBSCAN clustering algorithm and k-means clustering ...

Rectifying full-counting statistics in a spin Seebeck engine [PDF]

open access: yesPhys. Rev. B 97, 081407 (2018), 2017
We investigate the rectification and negative differential effects of full-counting statistics of conjugate thermal spin transport in a spin Seebeck engine. The engine is made by an electron/magnon interface diode driven by a temperature bias, of which the scaled cumulant generating function is formulated in the framework of nonequilibrium Green's ...

Designing a highly efficient graphene quantum spin heat engine [PDF]

open access: yesScientific Reports 9: 6018 (2019), 2017
We design a quantum spin heat engine using spin polarized ballistic modes generated in a strained graphene monolayer doped with a magnetic impurity. We observe remarkably large efficiency and large thermoelectric figure of merit both for the charge as well as spin variants of the quantum heat engine.

Maxwell's Demon for Quantum Transport [PDF]

open access: yesarXiv, 2023
Maxwell's demon can be utilized to construct quantum information engines. While most of the existing quantum information engines harness thermal fluctuations, quantum information engines that utilize quantum fluctuations have recently been discussed. We propose a new type of genuinely quantum information engine that harnesses quantum fluctuations to ...

Gap bootstrap methods for massive data sets with an application to transportation engineering [PDF]

open access: yes, 2012
In this paper we describe two bootstrap methods for massive data sets. Naive applications of common resampling methodology are often impractical for massive data sets due to computational burden and due to complex patterns of inhomogeneity.
