Cored Hypergraphs, Power Hypergraphs and Their Laplacian H-Eigenvalues
Shenglong Hu, Liqun Qi, Jia-Yu Shao
In this paper, we introduce the class of cored hypergraphs and power hypergraphs, and investigate the properties of their Laplacian H-eigenvalues. From an ordinary graph, one may g…
Blocks of affine quantum Schur algebras
Qiang Fu
The affine quantum Schur algebra is a certain important infinite dimensional algebra whose representation theory is closely related to that of quantum affine . Finite…
Determination of the magnetization profile of Co/Mg periodic multilayers by magneto-optic Kerr effect and X-ray magnetic resonant reflectivity
Philippe Jonnard, K. Le Guen, Jean-Michel André +8
The resonant magnetic reflectivity of Co/Mg multilayers around the Co L2,3 absorption edge is simulated then measured on a specifically designed sample. The dichroic signal is obta…
Hidden instability as an itinerant origin of bicollinear antiferromagnetism in FeTe
Ming-Cui Ding, Hai-Qing Lin, Yu-Zhong Zhang
By calculating orbitally resolved Pauli susceptibilities within maximally localized Wannier orbital basis transformed from first principles band structures, we find that magnetism…
Different Asymptotic Spreading Speeds Induced by Advection in a Diffusion Problem with Free Boundaries
Hong Gu, Zhigui Lin, Bendong Lou
In this paper, we consider a Fisher-KPP equation with an advection term and two free boundaries, which models the behavior of an invasive species in one dimension space. When sprea…
Efficient Data Gathering in Wireless Sensor Networks Based on Matrix Completion and Compressive Sensing
Jiping Xiong, Jian Zhao, Lei Chen
Gathering data in an energy efficient manner in wireless sensor networks is an important design challenge. In wireless sensor networks, the readings of sensors always exhibit intra…
