The Extension for Mean Curvature Flow with Finite Integral Curvature in Riemannian Manifolds
Hong-Wei Xu, Fei Ye, En-Tao Zhao
We investigate the integral conditions to extend the mean curvature flow in a Riemannian manifold. We prove that the mean curvature flow solution with finite total mean curvature o…
Local and global approaches of affinity propagation clustering for large scale data
Dingyin Xia, Fei Wu, Xuqing Zhang +1
Recently a new clustering algorithm called 'affinity propagation' (AP) has been proposed, which efficiently clustered sparsely related data by passing messages between data points.…
Transmission gap, Bragg-like reflection, and Goos-Hänchen shifts near the Dirac point inside a negative-zero-positive index metamaterial slab
Xi Chen, Li-Gang Wang, Chun-Fang Li
Motivated by the realization of the Dirac point (DP) with a double-cone structure for optical field in the negative-zero-positive index metamaterial (NZPIM), the reflection, transm…
Efficient randomized-adaptive designs
Feifang Hu, Li-Xin Zhang, Xuming He
Response-adaptive randomization has recently attracted a lot of attention in the literature. In this paper, we propose a new and simple family of response-adaptive randomization pr…
Delay-Optimal Power and Precoder Adaptation for Multi-stream MIMO Systems
Vincent K. N. Lau, Yan Chen
In this paper, we consider delay-optimal MIMO precoder and power allocation design for a MIMO Link in wireless fading channels. There are data streams spatially multiplexed ont…
Spin Gap and Resonance at the Nesting Wavevector in Superconducting FeSe0.4Te0.6
Yiming Qiu, Wei Bao, Yang Zhao +9
Neutron scattering is used to probe magnetic excitations in FeSe_{0.4}Te_{0.6} (T_c=14 K). Low energy spin fluctuations are found with a characteristic wave vector th…
