Intrinsic Grain Boundary Shear Coupling Tensor
Xinyuan Song, Liang Yang, Chuang Deng
Grain boundary (GB) migration stands as a linchpin process governing microstructural evolution in polycrystalline materials. Over the past decade, the concept of shear coupling, qu…
High-order accurate well-balanced energy stable finite difference schemes for multi-layer shallow water equations on fixed and adaptive moving meshes
Zhihao Zhang, Huazhong Tang, Junming Duan
This paper develops high-order well-balanced (WB) energy stable (ES) finite difference schemes for multi-layer (the number of layers ) shallow water equations (SWEs)…
The geometric constraints on Filippov algebroids
Yanhui Bi, Zhixiong Chen, Zhuo Chen +1
Filippov n-algebroids are introduced by Grabowski and Marmo as a natural generalization of Lie algebroids. On this note, we characterized Filippov n-algebroid structures by conside…
Im2win: Memory Efficient Convolution On SIMD Architectures
Shuai Lu, Jun Chu, Xu T. Liu
Convolution is the most expensive operation among neural network operations, thus its performance is critical to the overall performance of neural networks. Commonly used convoluti…
Quantum super-resolution for imaging two pointlike entangled photon sources
Huan Zhang, Wei Ye, Ying Xia +2
We investigate the resolution for imaging two pointlike entangled sources by using the method of the moments and the spatial-mode demultiplexing (SPADE), where the pointlike entang…
High-order accurate well-balanced energy stable adaptive moving mesh finite difference schemes for the shallow water equations with non-flat bottom topography
Zhihao Zhang, Junming Duan, Huazhong Tang
This paper proposes high-order accurate well-balanced (WB) energy stable (ES) adaptive moving mesh finite difference schemes for the shallow water equations (SWEs) with non-flat bo…
