Identification of Important FPGA Modules Based on Complex Network

The globalization of hardware designs and supply chains,as well as the integration of third-party intellectual property(IP)cores,has led to an increased focus from malicious attackers on computing hardware.However,existing defense or detection approaches often require additional circuitry to perform security verification,and are thus constrained by time and resource limitations.Considering the scale of actual engineering tasks and tight project schedules,it is usually difficult to implement designs for all modules in field programmable gate array(FPGA)circuits.Some studies have pointed out that the failure of key modules tends to cause greater damage to the network.Therefore,under limited conditions,priority protection designs need to be made on key modules to improve protection efficiency.We have conducted research on FPGA designs including single FPGA systems and multi-FPGA systems,to identify key modules in FPGA systems.For the single FPGA designs,considering the topological structure,network characteristics,and directionality of FPGA designs,we propose a node importance evaluationmethod based on the technique for order preference by similarity to an ideal solution(TOPSIS)method.Then,for the multi-FPGA designs,considering the influence of nodes in intra-layer and inter-layers,they are constructed into the interdependent network,and we propose a method based on connection strength to identify the important modules.Finally,we conduct empirical research using actual FPGA designs as examples.The results indicate that compared to other traditional indexes,node importance indexes proposed for different designs can better characterize the importance of nodes.

National Social Investment Programmes in Nigeria:A Descriptive Analysis of the Socio-Economic Contributions of N-Power Programme in Benue State

This study analysed the socio-economic contributions of N-Power programme amongst the beneficiaries of the scheme in Benue State.Prior to the introduction of N-Power programme,successive administrations in Nigeria have made concerted efforts towards improving the standard of living of the citizenry through the execution of various welfare or social intervention programmes,but not much successes were recorded.Learning from the mistakes of the past regimes,and by way of deliberate state policy,the Buhari’s government initiated a multi-pronged social investment policy,one of which is the N-power programme that came onboard in 2016,which also doubles as the subject of this study.To achieve the goal of this study,a combination of desktop research and survey design was employed.Questionnaires were administered to 390 respondents through a combination of stratified and random sampling techniques.The results of the survey were matched with that of the secondary data obtained through online websites and other related sources.The result indicated that N-Power made positive contributions to the socio-economic life of the beneficiaries in Benue State:specifically,the scheme contributed in poverty eradication,employment generation,skills acquisitions and capacity building.However,some aspect of our findings revealed that the programme has a number of challenges such as:inadequate cash support,delay in monthly cash transfer to beneficiaries,distance participants had to move to their work stations,absence of posting in N-Teach scheme,and lack of adequate working tools amongst others.To salvage this problem the paper recommended the following solutions:expansion of the scheme to cover N-Teach and other aspects,increment in the monthly cash transfer to cushion the high rate of inflation,support for the participants/beneficiaries in transportation and logistics,enrolment of more youth into the various schemes,proper monitoring and evaluation of the implementation of the schemes amongst others.

Beyond statistical significance:Embracing minimal clinically important difference for better patient care

The minimal clinically important difference(MCID)represents a pivotal metric in bridging the gap between statistical significance and clinical relevance,addressing the direct impact of medical interventions from the patient's perspective.This comprehensive review analyzes the evolution,applications,and challenges of MCID across medical specialties,emphasizing its necessity in ensuring that clinical outcomes not only demonstrate statistical significance but also offer genuine clinical utility that aligns with patient expectations and needs.We discuss the evolution of MCID since its inception in the 1980s,its current applications across various medical specialties,and the methodologies used in its calculation,highlighting both anchor-based and distribution-based approaches.Furthermore,the paper delves into the challenges associated with the application of MCID,such as methodological variability and the interpretation difficulties that arise in clinical settings.Recommendations for the future include standardizing MCID calculation methods,enhancing patient involvement in setting MCID thresholds,and extending research to incorporate diverse global perspectives.These steps are critical to refining the role of MCID in patient-centered healthcare,addressing existing gaps in methodology and interpretation,and ensuring that medical interventions lead to significant,patient-perceived improvements.

Important edge identification in complex networks based on local and global features

Identifying important nodes and edges in complex networks has always been a popular research topic in network science and also has important implications for the protection of real-world complex systems.Finding the critical structures in a system allows us to protect the system from attacks or failures with minimal cost.To date,the problem of identifying critical nodes in networks has been widely studied by many scholars,and the theory is becoming increasingly mature.However,there is relatively little research related to edges.In fact,critical edges play an important role in maintaining the basic functions of the network and keeping the integrity of the structure.Sometimes protecting critical edges is less costly and more flexible in operation than just focusing on nodes.Considering the integrity of the network topology and the propagation dynamics on it,this paper proposes a centrality measure based on the number of high-order structural overlaps in the first and second-order neighborhoods of edges.The effectiveness of the metric is verified by the infection-susceptibility(SI)model,the robustness index R,and the number of connected branchesθ.A comparison is made with three currently popular edge importance metrics from two synthetic and four real networks.The simulation results show that the method outperforms existing methods in identifying critical edges that have a significant impact on both network connectivity and propagation dynamics.At the same time,the near-linear time complexity can be applied to large-scale networks.

The minimal clinically important difference for gait speed in significant unilateral vestibular hypofunction after vestibular rehabilitation

Gait speed is a valid measure of both physical function and vestibular health.Vestibular rehabilitation is useful to improve gait speed for patients with vestibular hypofunction,yet there is little data to indicate how changes in gait speed reflect changes in patient-reported health outcomes.We determined the minimal clinically important difference in the gait speed of patients with unilateral vestibular hypofunction,mostly due to deafferentation surgery,as anchored to the Dizziness Handicap Index and the Activities Balance Confidence scale,validated using regression analysis,change difference,receiveroperator characteristic curve,and average change methods.After six weeks of vestibular rehabilitation,a change in gait speed from 0.20 to 0.34 m/s with 95%confidence was required for the patients to perceive a significant reduction in perception of dizziness and improved balance confidence.

Moisture Sources and Their Contributions to Summer Precipitation in the East of Southwest China

Complex topography,special geographical location and sea-land-air interactions lead to high interannual variability of summer precipitation in the east of Southwest China(ESWC).However,the contributions,influencing factors and mechanisms of remote and local evaporation remain to be further investigated.Using clustering analysis and Hybrid Single-Particle Lagrangian Integrated Trajectory version 5 model,we analyze the contributions of remote moisture transport and local evaporation to summer precipitation in the ESWC and their causes.There are mainly five remote moisture channels in the ESWC,namely the Arabian Sea channel,Bay of Bengal channel,western Pacific channel,Northwest channel 1 and Northwest channel 2.Among the five channels,the western Pacific channel has the largest number of trajectories,while the Bay of Bengal channel has the largest contribution rate of specific humidity(33.33%)and moisture flux(33.14%).The amount of regional average precipitation is close to that of the precipitation caused by remote moisture transport,and both are considerably greater than the rainfall amount caused by local evaporation.However,on interannual time scales,precipitation recirculation rates are negatively correlated to regional average precipitation and precipitation caused by remote moisture transport but are consistent with that caused by local evaporation.An apparent"+-+"wave train can be found on the height anomaly field in East Asia,and the sea surface temperature anomalies are positive in the equatorial Middle-East Pacific,the South China Sea,the Bay of Bengal and the Arabian Sea.These phenomena cause southwest-northeast moisture transport with strong updrafts,thereby resulting in more precipitation in the ESWC.

基于对我国重要农产品生产、消费和进口历史变化情况的分析,以及对2035年前变化趋势的预测,认为我国重要农产品供给保障面临国内增产边际效应递减和利用国际市场风险增大的双重挑战,应从统筹国内和国际两个大局、发展和安全两件大事出发,谋划好现代化新征程重要农产品供给保障思路。一方面,应从供需两侧入手扩产能、控消费,构建农业综合生产能力内在增长机制,针对农民务农种粮和地方重农抓粮逻辑采取差异化扶持政策,推进节粮减损、倡导节约消费;另一方面,应实施农产品进口多元化战略,提高海外供应链稳定性可靠性;此外,还应推动建立统一、联动的全国农产品大市场,完善农产品储备调节制度。

新《公司法》若干重要问题解读(笔谈)

新《公司法》修订所涉及的内容非常丰富,修订内容包括公司登记制度、股东出资责任、公司治理制度、公司资本制度、控股股东义务、董监高信义义务等方面。赵旭东教授指出,本次《公司法》修订在公司登记与信息公示制度、股东出资责任和法律后果、公司资本制度、公司治理制度、股东权益保护和控股股东义务这五个关键领域实现了重大突破和创新。周林彬教授集中解析了“国家出资公司组织机构的特别规定”一章,认为新《公司法》的亮点之一是通过新设这一章积极回应了我国国有企业治理的“本土实践”与“中国问题”,给出新时期国有企业治理的“中国方案”,推进了中国特色的国有企业治理制度的设计,重塑了国有企业的规范体系。刘凯湘教授对本次《公司法》修订中与公司资本制度相关的若干条文展开解析,包括限期认缴制、新增有限公司股东出资义务加速到期制度、股东违反出资义务的责任承担规则、董事会的催缴出资义务、股东失权制度、董监高对股东抽逃出资的连带责任、类别股的规定、授权资本制等。赵万一教授深入探讨了这次《公司法》修改的主要特点,认为新《公司法》既坚持了其商法属性,同时又充分考虑了《民法典》的既有制度内容,适当兼顾了与《民法典》之间的制度衔接关系,从而既为科学解决民法与商法的关系提供了理念和制度支持,也为中国式法律制度体系的创建提供了完美的立法实践样本。周友苏教授深入解析了新《公司法》在完善股东出资制度方面增加的股东出资缴纳、股东出资“加速到期”、股东失权、股东出资责任这四条新规定,认为新《公司法》在完善股东出资制度方面增加的这些新规定,积极回应了我国自2013年以来公司数量大幅增长所带来的股东盲目认缴、天价认缴、期限过长的现象突出,损害债权人利益的纠纷案件呈明显上升态势等问题,极大地强化了保护债权人的力度。李建伟教授深入解析了《公司法》修订中与法定代表人制度相关的若干条文,认为新《公司法》关于法定代表人的规定较之以往更加体系化,并有望基本解决困扰公司实践许多年的诸多难题,但其中亦存在不完全规范的问题。

基于农产品进出口贸易视角的农业机械化发展研究

为推进全程全面绿色高效农业机械化发展,基于农产品进出口贸易的视角分析农业机械化存在的短板弱项问题。目前我国农业存在贸易逆差逐年增加、主要农产品贸易逆差扩大、劳动密集型农产品比较优势逐渐消失、主要农产品自给率较低等发展现状。在农业机械化方面,小农经济及二元经济结构现状制约着适度规模经营的发展进度,农业规模化种植的生产效益还未充分体现;全程全面高质高量农业机械还不充分;全程农业机械化种植农艺技术推广应用还需加强。农业机械化发展应立足于保障粮食安全与提高农业经营主体经济效益的基本定位,关键在于提高农产品生产效率,改善农产品质量,提高农产品国际竞争力。基于上述分析,提出推进适度规模经营、推动短板弱项农业装备创新发展、优化农业机械化支持政策、推进先进适用农艺技术推广应用、强化农产品初加工装备研发及推广等发展建议。

《本草备要》药物十剂分类构成考察分析

唐代陈藏器《本草拾遗》药物十剂问世后,千余年间未能得到广泛传播和利用。研究表明,清代汪昂编撰《本草备要》时,大量标定药物十剂属性,并冠于药论之首,便于把握和选用;根据药物功能,提炼与药物功能吻合、单一或复合的十剂属性;大胆修改原十剂示范药物,扩充十剂属性的早期内涵。在充实和修改药物十剂方面做出了积极贡献。但因十剂去壅、去滞、去弱、去闭、去实、去怯、去脱、去着、去湿和去枯功能过于简约,且表达的象属性彼此重叠,随着归类后各剂药物数量的增加,超出原功能属性药物大量羼入,使十剂原始意涵发生不同程度的改变。故在阐明其学术价值和贡献时,应客观评价其得失。

养老保险省级统筹对养老保险基金平衡的影响研究

提高基本养老保险统筹层次是增强养老金支付能力的重要改革举措,也是实现养老金制度安全规范发展的关键。文章基于养老保险省级统筹改革的准自然实验,利用2008-2019年中国A股上市公司数据,构建双重差分模型实证评估了养老保险统筹改革对企业实际缴费率及基本养老保险基金平衡的影响。研究发现:省级统筹显著降低了企业养老保险实际缴费率,该结果在更改变量度量方式、排除竞争性解释、考虑异质性处理效应等一系列稳健性检验中仍然成立。养老保险省级统筹在不同征管模式、企业类型及地区层面对企业养老保险实际缴费率存在异质性影响,对于社保征收和税务代征模式、劳动密集度高的企业、所在地区老龄化程度低和财政压力小的企业影响更明显。机制分析发现,市县政府由于“相对剥夺效应”和“逐底竞争效应”所产生的征管强度不足是造成省级统筹改革后企业缴费率下降的重要因素。进一步分析表明,省级统筹改革降低了基金收支平衡,并对中西部省份影响更明显。研究对于加强地方政府征管治理、促进养老保险基金平衡发展具有重要启示,为征管主体间利益关系的平衡及养老保险全国统筹的顺利推进提供了经验证据。

催缴失权制度的法理基础与体系展开

作为新《公司法》创设的一项新制度,催缴失权制度的法理基础及其解释适用亟待阐释。在适用范围上,应将催缴失权制度扩张适用于所有股东未按期足额缴纳货币或非货币出资以及抽逃出资的情形。出资义务加速到期后未按期缴资的股东,可适用失权制度。采取催缴书还是诉讼方式催缴、是否载明不少于60日宽限期、是否发出失权通知等,需借由董事商业判断;董事在判断时应遵循股东平等原则。在法律后果上,股东完全未出资或者抽逃全部出资导致丧失全部股权的,同时丧失股东资格;反之则否。在救济途径上,失权异议之诉排除决议效力瑕疵诉讼在失权异议中的适用。
