Clustering routing protocols excel in several aspects of wireless sensor networks （WSNs）. This article proposes a clustering and multihop routing protocol （CMRP）. In CMRP, a node independently makes its decision to compete for becoming a cluster head or join a cluster, according to its residual energy and average broadcast power of all its neighbors. To minimize the power consumption of the cluster head, CMRP sends the data in a power-aware multihop manner to the base station （BS） through a quasi-fixed route （QFR）. In addition, CMRP presents a transmission power control algorithm with dynamic intercluster neighbor position estimation （DCNPE） to save energy. Simulation results show that the performance of CMRP is better than the hybrid, energy-efficient, distributed clustering approach （HEED）. In the best case, CMRP increases the sensor network lifetime by 150.2%.

深度学习技术在不同领域有着广泛的应用,然而一个训练好的深度学习模型很容易受到干扰而得出错误的结果,从而引发严重的安全问题.为了检验深度学习模型的抗干扰性,提高模型的安全性和鲁棒性,有必要使用对抗样本进行对抗评估和对抗训练.有目标的黑盒对抗样本的生成方法具有较好的实用性,是该领域的研究热点之一.有目标的黑盒对抗样本生成的难点在于,如何在保证攻击成功率的前提下提高对抗样本的生成效率.为了解决这一难点,本文提出了一种基于快速边界攻击的有目标攻击样本生成方法.该方法包括线上的搜索和面上的搜索两步.线上的搜索由单侧折半法来完成,用于提高搜索效率;面上的搜索通过自适应调节搜索半径的随机搜索完成,用于提高搜索的广度.通过对5组图片的实验结果验证了方法的可行性.

The instantaneous detection of entanglement in quantum states poses a significant challenge in the fields of quantum computation and quantum information, and there are no practical methods or tools to complete this task satisfactorily so far. We propose a sufficient and necessary criterion of k-nonseparability for any n-partite finite or infinite dimensional systems, 2 ≤ k ≤ n. This criterion serves as the foundation for a practical scheme designed to detect entanglement and k-nonseparability across multipartite finite-dimensional systems. To exemplify the application of our scheme, we have developed a software tool that facilitates swift and precise identification of entanglement, k-nonseparability, and genuine entanglement within n-qubit systems, specifically tailored for systems with 2 ≤ n ≤ 4.

《1844年经济学哲学手稿》和《神圣家族,或对批判的批判所作的批判》是马克思早年的两部著作。在《神圣家族》中马克思确立了自己科学的唯物史观,而在此之前的《手稿》则明显带有费尔巴哈人本主义的特征,它们之间的美学思想是有着明显的差别的,同时《手稿》中唯物观的雏形与《神圣家族》中科学的唯物史观又是一脉相承的。
