Spin-orbit torque （SOT）,as a promising writing method for magnetic random-access memory （MRAM）,has garnered widespread interest for over a decade [1].Heavy metals,such as β-W,have been broadly adopted as spin current sources,but suffer from phase change at a limited thickness,resul.ing in a dramatic reduction of the charge-tospin conversion efficiency θSH[2].The thickness limitation leads to stringent etching conditions and large distribution among devices,posing challenges for simultaneously satisfying SOT efficiency,etching-stop margins,and back-end-ofline （BEOl） compatibility.

横向部门间的协同合作是中国政府运作和政策运行的关键环节之一。只有深度考察部门间协同的具体发生过程,才能找到有效治理跨部门事务的可行之策。本文立足于l市跨部门协同监管的实际案例,构建了中国情境下跨部门“迭代性协同”的解释框架,重新审视协同如何萌生、为何中断、何以持续的全周期发展问题。研究发现,部门间协同是一个围绕政策反馈与调试的动态实践过程,通过对协同结果的反复运算与评估,不断逼近政策目标,直至实现治理效能的最大化。本文认为,这样一种迭代性协同遵循着“协同过程-协同机制-协同情景”三重嵌套的实质逻辑,展现了中国地级市政府跨部门协同“从无到有”的发生过程,希冀为开展跨部门综合监管的顶层设计和政策执行提供有益的政策启示。

The estimation of carbon exchange between ecosystems and the atmosphere suffers unavoidable data gaps in eddy-covariance technique, especially for short-living and fast-growing croplands. in this study we developed a modified gap-fil.ing scheme introducing a leaf area index factor as the vegetation status information based on the conventional light response function for two East-Asian cropland sites (rice and potatoes). This scheme’s performance is comparable to the conventional time window scheme, but has the advantage when the gaps are large compared to the total length of the time series. To investigate how the time binning approach performs for fast-growing croplands, we tested different widths of the time window, showing that a four-day window for the potato field and an eight-day time window for the rice field perform the best. The insufficiency of the conventional temperature binning approach was expl.ined as well as the influence of vapor pressure deficit. We found that vapor pressure deficit plays a minor role in both the potato and the rice fields under Asian monsoon weather conditions with the exception of the early pre-monsoon growing stage of the potatoes. Consequently, we recommend using the conventional time-window scheme together with our new leaf-light response function to fill data gaps of net ecosystem exchange in fast-growing croplands.

针对电动汽车充电网络可能因局部超载或故障而形成级联失效的问题,提出了一种基于多推荐策略的电动汽车充电网络鲁棒性分析方法。其采用Space-l方法构建充电网络拓扑结构,并引入负载-容量级联失效模型,基于距离、快充桩数量、用户偏好、价格和总评分等推荐策略,评估了不同推荐策略下充电网络的动态响应。仿真结果表明,在特定节点失效比下,不同推荐策略均导致了最大连通子图相对大小的突变,经过识别触发突变的失效节点所对应充电站的经纬度,即可识别充电网络中的关键节点,验证了本文所提方法的正确性。

The development of RNA interference(RNAi) therapy offers a potential solution for Alzheimer's disease(AD). However, the brain-blood barrier(BBB) with its selective permeability and pharmacokinetic-related challenges poses restrictions on the delivery of small.interfering RNA(siRNA) to the central nervous system(CNS). in this study, we demonstrate that the incorporation of 2'-fluoro(2'-F) substitutions and l-carnitine modification facilitates the self-assembly of siRNA through triple interaction, leading to the formation of nanorings, called lCSF-NR. Based on the enhanced cellular uptake and lysosomal escape by 2'-F substitution and the transport across the BBB promoted by l-carnitine, the nanorings realized the improved braintargeted delivery of siRNA, both in zebrafish and mice models. Moreover, our findings highlight the therapeutic potential of lCSF-NR formulation in an AD zebrafish model through a synergistic effect of downregulating the β-site APP cleavage enzyme1(BACE1) gene and l-carnitine-mediated neuroprotection, effectively inhibiting pathological processes. Overall, these results suggest that the chemical modification-based siRNA self-assembly strategy enables trans-BBB delivery and presents a concise approach for synergistic therapy of AD.

构建和优化生态网络对解决当前生态问题、保障区域生态安全、实现可持续发展具有重要意义。然而,当前生态网络优化研究鲜有多目标优化研究,更是忽视了多个优化目标间协同优化的作用,缺乏系统的优化框架。因此,提出一种“生态盲区削减⁃网络功能结构协调”的双目标协同优化框架,并以武汉市为例开展实证研究。运用最小累积阻力模型构建初始生态网络,并开展生态盲区指导下的生态网络优化;然后,基于协调性分析,针对功能结构异配节点,提出针对性的优化措施;采用鲁棒性和结构指数对优化前后生态网络进行评价。结果表明:(1)武汉市初始生态网络含生态源地17个,生态廊道47条,空间分布呈不均衡性;(2)经调整型生态源地、新增型生态源地、补充生态廊道和非源地斑块优化后,生态盲区占比从31.77%降至15.37%;(3)新增17条廊道,实施三级差异化生态建设后,实现了生态网络协调性;(4)优化后的生态网络结构指数α、β、γ分别提高69.16%、56.16%和47.12%,鲁棒性也更强。研究得出,该双目标协同优化模型不仅能够实现各自的优化目标,还能增强生态网络的稳定性。该模型将为生态网络优化研究提供新视角和系统框架,案例结果将为武汉市削减生态盲区、建设功能与结构协调的生态网络提供理论和方法指导。
