Symmetries and Local Conservation Laws of Variational Schemes for the Surface Plasmon Polaritons
Qiang Chen, Xiaojun Hao, Chuanchuan Wang +3
The relation between symmetries and local conservation laws, known as Noether's theorem, plays an important role in modern theoretical physics. As a discrete analog of the differen…
Variational Schemes and Geometric Simulations for a Hydrodynamic-Electrodynamic Model of Surface Plasmon Polaritons
Qiang Chen, Lifei Geng, Xiang Chen +3
A class of variational schemes for the hydrodynamic-electrodynamic model of lossless free-electron gas in a quasineutral background is developed for high-quality simulations of sur…
Robust Group LASSO Over Decentralized Networks
Manxi Wang, Yongcheng Li, Xiaohan Wei +1
This paper considers the recovery of group sparse signals over a multi-agent network, where the measurements are subject to sparse errors. We first investigate the robust group LAS…
Improved Upper Bounds on Systematic-Length for Linear Minimum Storage Regenerating Codes
Kun Huang, Udaya Parampalli, Ming Xian
In this paper, we revisit the problem of finding the longest systematic-length for a linear minimum storage regenerating (MSR) code with optimal repair of only systematic part,…
Security Concerns in Minimum Storage Cooperative Regenerating Codes
Kun Huang, Udaya Parampalli, Ming Xian
Here, we revisit the problem of exploring the secrecy capacity of minimum storage cooperative regenerating (MSCR) codes under the -eavesdropper model, where the eavesd…
On Secrecy Capacity of Minimum Storage Regenerating Codes
Kun Huang, Udaya Parampalli, Ming Xian
In this paper, we revisit the problem of characterizing the secrecy capacity of minimum storage regenerating (MSR) codes under the passive -eavesdropper model, where the…
