Abstract: 针对超声回波信号高相关性特性, 提出一种基于改进相干因子的延时乘累加(pCF-DMAS)波束形成算法并应用至平面波超声成像. 该算法通过增强相干因子的相干性来计算回波信号的权值, 然后进行乘累加运算.通过使用Field II进行超声点目标和囊肿目标的仿真实验, 对成像结果进行分析验证了算法的有效性.仿真结果表明, 算法具有优秀的横向分辨率, 在p取 0.7 时具有所有对比算法中的最高对比度.综合点目标和囊肿目标的成像效果, 给出算法的最优p值0.3.相比延时叠加和延时乘累加波束形成算法, 所提算法的...

Density matrices of seniority-zero geminal wavefunctions.

Publication Type: Academic Journal

Source(s): Journal of Chemical Physics. 6/7/2022, Vol. 156 Issue 21, p1-20. 20p.

Abstract: Scalar products and density matrix elements of closed-shell pair geminal wavefunctions are evaluated directly in terms of the pair amplitudes, resulting in an analog of Wick's theorem for fermions or bosons. This expression is, in general, intractable,...

Dissecting Tensor Cores via Microbenchmarks: Latency, Throughput and Numeric Behaviors.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Parallel & Distributed Systems. Jan2023, Vol. 34 Issue 1, p246-261. 16p.

Abstract: Tensor Cores have been an important unit to accelerate Fused Matrix Multiplication Accumulation (MMA) in all NVIDIA GPUs since Volta Architecture. To program Tensor Cores, users have to use either legacy wmma APIs or current mma APIs. Legacy wmma APIs ...

Memory-Efficient Algorithm for Scalar Multiplications on Twisted Edwards Curves for Isogeny-Based Cryptosystems.

Publication Type: Academic Journal

Source(s): Mathematical Problems in Engineering. 4/27/2022, p1-8. 8p.

Abstract: Scalar multiplications are considered an essential aspect of implementations of isogeny-based cryptography. The efficiency of scalar multiplication depends on the equation of the underlying elliptic curves and the addition chain employed. Bos and Fried...
