To overcome imperfection of exhaustive based beam searching scheme in IEEE 802.15.3c and IEEE 802.11 ad and accelerate the beam training process, combined with the fast beam searching algorithm previously proposed, this paper proposed a beam codebook design scheme for phased array to not only satisfy the fast beam searching algorithm's demand, but also make good use of the advantage of the searching algorithm. The simulation results prove that the proposed scheme not only performs well on flexibility and searching time complexity, but also has high success ratio.

活力和秩序有机统一的必要前提,是构建国家秩序治理的边界,避免其对活力的“恣意”干预。现有理论将国家介入社会纠纷的边界诉诸于程序政治和形式理性,但该逻辑与转型中的治理现实存在明显断裂。论文发现,国家介入纠纷解决的本土实践,不是国家简单提升损益的干预力度和规则刚性,而是强调以行政统合全面吸纳诉求并构建整体同意;不是被动守住底线预期,而是通过形式法治主动嵌入社会,确保多元规则体系的整体可靠;不仅是从外部协助推进妥协与协商,更是以总体领导推动信任、交往与合作的良性循环。文章认为,这些多样和特殊的本土调适背后,呈现的是“体制化能动”的实践逻辑,这构成国家介入纠纷解决的清晰指引和可靠约束。

In this big data era, the explosive growth of information puts ultra-high demands on the data storage/computing, such as high computing power, low energy consumption, and excellent stability. However, facing this challenge, the traditional von Neumann architecture-based computing system is out of its depth owing to the separated memory and data processing unit architecture. One of the most effective ways to solve this challenge is building brain inspired computing system with in-memory computing and parallel processing ability based on neuromorphic devices. Therefore, there is a research trend toward the memristors, that can be applied to build neuromorphic computing systems due to their large switching ratio, high storage density, low power consumption, and high stability. Two-dimensional (2D) ferroelectric materials, as novel types of functional materials, show great potential in the preparations of memristors because of the atomic scale thickness, high carrier mobility, mechanical flexibility, and thermal stability. 2D ferroelectric materials can realize resistive switching (RS) because of the presence of natural dipoles whose direction can be flipped with the change of the applied electric field thus producing different polarizations, therefore, making them powerful candidates for future data storage and computing. In this review article, we introduce the physical mechanisms, characterizations, and synthetic methods of 2D ferroelectric materials, and then summarize the applications of 2D ferroelectric materials in memristors for memory and synaptic devices. At last, we deliberate the advantages and future challenges of 2D ferroelectric materials in the application of memristors devices.

数学多元论(或集合论多宇宙论)是近年来数学哲学中逐渐流行的哲学立场。数学多元论具有不同的数学与哲学动机,其中哲学上的一个重要动机是解决传统实在论者面临的贝纳塞拉夫问题。根据多元论,任何一致的理论都现实为真,因此对数学信念可靠性的解释可以转化为对一致性信念的解释。许多哲学家也认为数学多元论是唯一能够应对贝纳塞拉夫挑战的实在论立场。然而事实上,多元论者的一致性概念是个不稳定的概念,诉诸一致性并不能解决传统实在论者面临的认识论问题。
