Spintronic devices based on spin orbit torques(SOT)exhibit advantages in low power consump-tion,high speed,reconfigurability,and high endurance,which offers the prospect of in-memory computing based on spin logic devices.By designing a local spin current gradient,the magnetization can be switched deterministically by asymmetric spin currents without external magnetic field using micromagnetic simu-lations,where an additional out of plane effective field can be generated by the spin gradient.Through capping half of the Pt/Co/Pt SOT devices with Pt strip,we demonstrate the field-free deterministic current-induced magnetization switching experimentally.Finally,we design AND,NAND,OR,and NOR Boolean logic gates based on these devices,which could be used as building blocks for programmable and stateful logic operations.

Load balancing mechanism in technologies such as cloud computing has provided a huge oppor-tunity for the development of large-scale projects.Although the conventional view is to build mechanisms that adopt a dynamic load balancing strategy,existing strat
随着中国政治、经济、社会、文化、生态文明的不断发展，人们越来越认识到美好生活离不开中国共产党的领导。只有在党的领导下，我们才能在这个国际社会动荡不安的大形势下安全生活。因此，党只有不断提高自身的执政能力，才能更好地为全体人民服务；党员队伍只有加强党的建设，才能始终保持党的纯洁性和先进性。基层党校作为培养基层人员和领导干部的重要部门，是党委的重要组成部分，承担着培训党员干部的重要职能。当前，基层党校在进行政治理论教育的过程中存在着明显的问题。本文从分析问题入手，提出提高基层党校政治理论教育水平的策略。
A lot of natural language processing problems need to encode the text sequence as a fix-length vector,which usually involves an aggregation process of combining the representations of all the words,such as pooling or self-attention.However,these widely us
收入保险能够同时保障产量和价格两方面风险,同时合乎WTO贸易协定的绿箱政策规则,正逐步成为中国农业保险市场力推的主要产品类型.结合国际实践经验,以中国2001-2019大豆种植数据为基础,使用Copula函数等方法,对是否附加收获期价格期权条款的两种收入保险方案(RP-HPO和RP-HPE)的费率水平和赔付分布进行了测算,结果表明,大豆收入保险在75％～100％的保障程度下,RP-HPO方案费率水平在2.4％～12.1％之间,RP-HPE方案费率水平在2.4％～11.4％之间,费率上升幅度有限;无论是HP

传统测量叶面积方法费时、低效,叶面积仪法高成本、维修不便.本研究利用图像处理技术测量叶面积,从解决图像阈值的分割、叶片阴影去除以及叶片边缘检测算法等问题出发,应用大津法求得阈值,中值滤波法去除杂点,采用Roberts算子检测边缘,进而计算叶面积.叶面积仪法与图像处理法比较叶面积值相关系数R2为0.962,剪纸法与图像处理法比较叶面积值相关系数R2为0.949,最后验证本方法适合大量叶面积的测量工作,且具有速度快、数据准确、精度高的特点.
为提高园林植物配植水平,从植物群落林冠线和色彩2个方面对景观外貌进行量化分析.研究选取3处居住区中心绿地,测算样本材料的林冠线分形维数和色彩信息维数.研究发现,所选样本植物群落林冠线分形维数组内变异差别较大而组间较小,样本景观塑造以植物群落为主搭配园林建筑分形维数较高,完全以植物造景林冠线较连续,更具自然韵味,群落内部不同层次植物的林冠轮廓分形维数变异性较大,林冠线不连续且以建筑轮廓线为主的景观分形维数较低;色彩的信息维数体现了色彩分布的复杂和不均匀性,维数较高是园林植物群落接近自然群落的特征之一.3个样
