PoC of SCMA-Based Uplink Grant-Free Transmission in UCNC for 5G
Zhang Jinfang,Lei Lu,Yuntao Sun,Yan Chen,Jiamei Liang,Liu Jin,Huilian Yang,Shuangshuang Xing,Yiqun Wu,Jianglei Ma,Ignacio Berberana Fernandez Murias,Francisco Javier Lorca Hernando +11 more
TL;DR: The focus is on proof of concept of UL grant-free transmissions in the UCNC architecture, which can reduce signaling overhead and transmission latency and is efficiently supported with the SCMA scheme that yields around 230% gain over OFDMA in terms of supported active users.
Journal ArticleDOI
A Cretaceous pole from south China, and the Mesozoic hairpin turn of the Eurasian apparent polar wander path
Randolph J. Enkin,Yan Chen,Vincent Courtillot,Jean Besse,Lisheng Xing,Zhenhai Zhang,Zhonghai Zhuang,Jingxin Zhang +7 more
TL;DR: In this paper, the authors present the results from 373 oriented cores taken from one section representing 3 km of sedimentary rocks and conclude that the remanence was acquired within the time corresponding to the tip of the hairpin turn (∼150-50 Ma).
Proceedings ArticleDOI
Tomography-based overlay network monitoring
TL;DR: In this paper, the authors characterize end-to-end losses in overlay networks, including latency and packet loss, rather than individual link losses, and find a minimal basis set of k linearly independent paths that can fully describe all the O(n, 2) paths.
Journal ArticleDOI
Hop ID: A Virtual Coordinate based Routing for Sparse Mobile Ad Hoc Networks
TL;DR: This paper proposes a new Hop ID routing scheme, which is a virtual coordinate-based routing protocol and does not require any location information and achieves excellent routing performance comparable with that obtained by the shortest path routing schemes.
Journal ArticleDOI
Real-time Biomechanically-based Muscle Volume Deformation using FEM
TL;DR: Voxel‐based wireframe, polygon surface rendering, and volume rendering techniques are applied to show real‐time muscle deformation processes as well as realistic animations.
