Kavli Affiliate: Feng Wang | First 5 Authors: Pei Cao, Jinru Chen, Feng Wang, , | Summary: In this paper, we propose an extended mixed finite element method for elliptic interface problems. By adding some stabilization terms, we present a mixed approximation form based on Brezzi-Douglas-Marini element space and the piecewise constant function space, and […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Qiuxin Zhang, Yu Xiang, Xiaoting Gao, Chenhao Zhu, Yuxin Wang | Summary: Whether the observables of a physical system admit real values is of fundamental importance to a deep understanding of nature. In this work, we report a device-independent experiment to confirm that the joint reality of […]

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Songfu Cai, Vincent K. N. Lau, , | Summary: This paper studies a sequential task offloading problem for a multiuser mobile edge computing (MEC) system. We consider a dynamic optimization approach, which embraces wireless channel fluctuations and random deep neural network (DNN) task arrivals over […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Hebai Chen, Hao Yang, Rui Zhang, Xiang Zhang, | Summary: Characterizing existence or not of periodic orbit is a classical problem and it has both theoretical importance and many real applications. Here, several new criterions on nonexistence of periodic orbits of the planar dynamical system $dot x=y,~dot […]
Kavli Affiliate: Feng Wang | First 5 Authors: Haomin Sun, Hui Deng, Feng Wang, Ying Mei, Tingting Xu | Summary: The rapid development of new generation radio interferometers such as the Square Kilometer Array (SKA) has opened up unprecedented opportunities for astronomical research. However, anthropogenic Radio Frequency Interference (RFI) from communication technologies and other human […]
Kavli Affiliate: Joel E. Moore | First 5 Authors: Yan-Qi Wang, Roman Rausch, Christoph Karrasch, Joel E. Moore, | Summary: A strongly interacting plasma of linearly dispersing electron and hole excitations in two spatial dimensions (2D), also known as a Dirac fluid, can be captured by relativistic hydrodynamics and shares many universal features with other […]
Kavli Affiliate: Feng Wang | First 5 Authors: Jixiang Yang, Guorui Chen, Tianyi Han, Qihang Zhang, Ya-Hui Zhang | Summary: ABC-stacked trilayer graphene/hBN moir’e superlattice (TLG/hBN) has emerged as a playground for correlated electron physics. We report spectroscopy measurements of dual-gated TLG/hBN using Fourier transformed infrared photocurrent spectroscopy. We observed a strong optical transition between […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Tianxiang Zhao, Xiang Zhang, Suhang Wang, , | Summary: Edges in real-world graphs are typically formed by a variety of factors and carry diverse relation semantics. For example, connections in a social network could indicate friendship, being colleagues, or living in the same neighborhood. However, these latent […]
Kavli Affiliate: Feng Wang | First 5 Authors: Qing-Wen Deng, Feng Wang, Hui Deng, Ying Mei, Jing Li | Summary: The Square Kilometre Array (SKA) is the largest radio interferometer under construction in the world. Its immense amount of visibility data poses a considerable challenge to the subsequent processing by the science data processor (SDP). […]
