Double Index Calculus Algorithm: Faster Solving Discrete Logarithm Problem in Finite Prime Field

Autor: Huang, Wen, Zhang, Zhishuo, Zhao, Weixin, Peng, Jian, Liao, Yongjian, Wang, Yuyu

Solving the discrete logarithm problem in a finite prime field is an extremely important computing problem in modern cryptography. The hardness of solving the discrete logarithm problem in a finite prime field is the security foundation of numerous c

Peculiar Velocity Reconstruction From Simulations and Observations Using Deep Learning Algorithms

Autor: Wang, Yuyu, Yang, Xiaohu

In this paper, we introduce a Unet model of deep learning algorithms for reconstructions of the 3D peculiar velocity field, which simplifies the reconstruction process with enhanced precision. We test the adaptability of the Unet model with simulatio

Transport of intense ion beams in plasmas: collimation and energy-loss reduction

Autor: Zhao, Yongtao, Chen, Benzheng, Wu, Dong, Cheng, Rui, Zhou, Xianming, Lei, Yu, Wang, Yuyu, Qi, Xin, Xiao, Guoqing, Ren, Jieru, Wang, Xing, Hoffmann, Dieter H. H., Gao, Fei, Hu, Zhanghu, Wang, Younian, Yu, Wei, Fritzsche, Stephan, He, Xiantu

We compare the transport properties of a well-characterized hydrogen plasma for low and high current ion beams. The energy-loss of low current beams can be well understood, within the framework of current stopping power models. However, for high curr
