How to Make the Charging Simple, Convenient and Efficient

Наука и техника, 2020
With the large-scale application of electric vehicles (EV) in the world and also in China, the contradiction between the EV and charging stations has become more and more prominent. People always cannot easily find the charging stations or when they find

Poisson Matrix Completion [PDF]

, 2015
We extend the theory of matrix completion to the case where we make Poisson observations for a subset of entries of a low-rank matrix. We consider the (now) usual matrix recovery formulation through maximum likelihood with proper constraints on the ...

Matrix pentagons

, 2017
The Operator Product Expansion for null polygonal Wilson loop in planar maximally supersymmetric Yang-Mills theory runs systematically in terms of multiparticle pentagon transitions which encode the physics of excitations propagating on the color flux ...

Achieving structural white inspired by quasiordered microstructures in Morpho theseus

NPG Asia Materials, 2023
As one of the most fascinating phenomena, structural whiteness in natural organisms serves important functions in thermoregulation and mating. However, the architectures that cause visible broadband reflection are often in quasiordered distributions ...

Matrix string interactions [PDF]

, 1998
String configurations have been identified in compactified Matrix theory at vanishing string coupling. We show how the interactions of these strings are determined by the Yang-Mills gauge field on the worldsheet.

Construction of SnO2−Graphene Composite with Half-Supported Cluster Structure as Anode toward Superior Lithium Storage Properties

Scientific Reports, 2017
Inspired by nature, herein we designed a novel construction of SnO2 anodes with an extremely high lithium storage performance. By utilizing small sheets of graphene oxide, the partitioned-pomegranate-like structure was constructed (SnO2@C@half-rGO), in ...
