Sustainable Investment Forecasting of Power Grids Based on theDeep Restricted Boltzmann Machine Optimized by the Lion Algorithm

This paper proposes a new power grid investment prediction model based on the deep restricted Boltzmann machine(DRBM)optimized by the Lion algorithm(LA).Firstly,two factors including transmission and distribution price reform(TDPR)and 5G station construction were comprehensively incorporated into the consideration of influencing factors,and the fuzzy threshold method was used to screen out critical influencing factors.Then,the LA was used to optimize the parameters of the DRBM model to improve the model’s prediction accuracy,and the model was trained with the selected influencing factors and investment.Finally,the LA-DRBM model was used to predict the investment of a power grid enterprise,and the final prediction result was obtained by modifying the initial result with the modifying factors.The LA-DRBMmodel compensates for the deficiency of the singlemodel,and greatly improves the investment prediction accuracy of the power grid.In this study,a power grid enterprise was taken as an example to carry out an empirical analysis to prove the validity of the model,and a comparison with the RBM,support vector machine(SVM),back propagation neural network(BPNN),and regression model was conducted to verify the superiority of the model.The conclusion indicates that the proposed model has a strong generalization ability and good robustness,is able to abstract the combination of low-level features into high-level features,and can improve the efficiency of the model’s calculations for investment prediction of power grid enterprises.

The Policy of Energy Saving,Pollution Control and Carbon Reduction based on the Cause Analysis of“Power Restriction”Event

In recent years,the“power restriction”measures were taken in many localities,industrial electricity consumption was interrupted,mainly in the“two high”(high energy consumption and high pollutant emission)enterprises.Take the“power restriction”event in 2021 as an example,this event affected a wide range of regions and disrupted people’s livelihood.It not only refers to the power switch and rationing measures taken by individual regions,but also includes differentiated policies implemented by over 20 provinces to limit power supply and industrial production.This paper investigated in detail and summarized the different requirements of power restriction across the country,through the comparison of annual growth rates of power generation and industrial added value,the comparison results of energy intensity,electricity production,power consumption and the industrial growth rate in each province are analyzed.Industrial enterprises and related industrial chains were most heavily affected by the“power restriction”event,mainly in steel,cement,electrolytic aluminum,industrial silicon,textile printing and dyeing,chemical fiber,chemical and other enterprises with high energy consumption and high pollutants emission.The measures to limit electricity will affect the normal production of enterprises to a certain extent,leading to not only the decrease of production efficiency,but also the increase of energy consumption and pollutant emission per unit product.Energy management measures such as differentiated electricity price have limited effect on the output of“two high”industrial products,and the economic leverage of differentiated electricity price is gradually being diluted by the price rise of end products.This paper analyzed the reasons and explored several key problems that need special attention.then recommended certain countermeasures for its appropriate application in the future.

Research on Impact Mechanism and Power System of Urbanization in West China

Based on the current situation of urbanization development in West China, this paper analyses main factors responsible for sluggish urbanization in West China as follows: impact of environment factor, impact of population quality and quantity, lagging of public product service, stagnancy of technological development, backwardness of slow growth, and rigidity of system building. And then this paper analyses the restriction mechanism of urbanization in West China: at the superficial level, the constraints of urbanization in West China arise from the shortage of capital; at the profound level, the backward culture contributes to the constraints of urbanization in West China. The thread of resolving restriction mechanism of urbanization in West China is put forward from system, economy and culture. On the basis of this thread, we construct the power system for the development of urbanization in West China. The power system for urbanization in West China should be propelled by "four forces", namely, pull of external forces, cohesive strength of regional market environment, expansion power inside countryside, traction of industrial structure adjustment. Innovation is the engine of impetus for urbanization in West China; spatial clustering and modernization of industry is the major driving force for urbanization; the government behaviour, driving of foreign investment, great projects and other forces are supplementary power. Via the main power, we should take the market as medium to achieve the role of power in promoting urbanization.

孟德斯鸠犯罪治理思想探析

孟德斯鸠在犯罪与犯罪治理领域提出了独特的见解,他认为判定何种行为是犯罪应当依具体情况加以规定,并强调犯罪治理应当围绕制约权力、保障个人权利不受侵犯的原则展开。同时,他强烈反对过度使用重刑,极力倡导罪刑法定原则。这些观点构成了孟德斯鸠犯罪治理的核心思想,他进一步提出了一套制约治理权力与“刑、民、行”的综合治理体系,在依法治理的同时也认同良好的习俗与风尚在犯罪预防中的积极作用,从而达到有效预防犯罪和显著减少犯罪的双重目标。孟德斯鸠的这些观点不仅对后世产生深远影响,也为当代中国在犯罪治理领域提供了借鉴意义。

目的 分析早孕期三维能量多普勒联合频谱多普勒定量评估胎盘血流灌注预测胎儿生长受限(FGR)的相关性。方法 选取76例于天津中医药大学附属北辰中医医院2021年4月—2022年9月进行早孕期NT检查的孕妇为研究对象,根据胎儿是否存在生长受限分为对照组69例,FGR组7例。以此对比产妇基本资料,两组超声参数:胎盘血管化指数(VI)、胎盘血流指数(FI)、血管化-血流指数(VFI)、子宫动脉阻力指数(UtA-RI)、子宫动脉搏动指数(UtA-PI)、胎儿静脉导管搏动指数(DV-PI),分析发生FGR独立危险因素,超声参数与FGR的相关性,ROC曲线分析不同指标预测FGR的效能。结果 FGR与年龄、BMI指数、孕期贫血、产次无关,无统计学差异(P>0.05);主要与胎膜早破、羊水过少、脐带异常、胎粪污染、胎盘异常有关,具有统计学差异(P<0.05)。与对照组相比,FGR组VI、VFI、水平较低,UtA-RI、UtA-PI、DV-PI水平有所提升(P<0.05)。以FGR为因变量(0=否,1=是),建立Logistic回归模型,结果显示,VI、VFI、UtA-RI、UtA-PI、DV-PI是导致FGR的独立危险因素(P<0.05)。VI、VFI参数与FGR呈负相关;UtA-RI、UtA-PI、DV-PI参数与FGR呈正相关(P<0.05)。ROC曲线显示,VI、VFI、UtA-RI、UtA-PI、DV-PI单一及联合预测均有较高效能,而联合检查预测价值最高(P<0.05)。结论 早孕期采用三维能量多普勒联合频谱多普勒预测FGR的效能较高,有助于早期诊断并及时采取干预措施。

新时代加强对“一把手”监督的研究述评

高度重视“一把手”监督工作是新时代加强党和国家监督的内在需要。党的十八大以来,我国“一把手”监督工作实现了新发展,相应的理论研究也取得了新成果。从现有文献看,加强对“一把手”监督的内在机理在于“一把手”的特殊地位以及实践中存在的监督难题,监督思想源自无产阶级政党的权力监督与制约理论,监督困境体现在监督主体和客体双重层面,监督困境的原因在于权力分配不科学、监督机制不完善、文化支撑不足等。实践中,要提升对“一把手”监督的效能,需从调整“一把手”权力结构、加强监督文化建设、完善运行机制等方面推进,进一步细化聚焦研究议题、拓宽研究领域、深化理论研究。

路的k阶幂图的连通性研究

设G是连通图,G的k阶幂图G^(k)是一个与G具有相同顶点集的图,G^(k)中的两个顶点相邻当且仅当这两个顶点在G中的距离不大于k.本文研究了路的幂图P_(n)^(k)的点连通度κ(P_(n)^(k))、边连通度λ(P_(n)^(k))和限制边连通度λ_(2)(P_(n)^(k)).得到:当n>k时,κ(P_(n)^(k))=λ(P_(n)^(k))=k;关于限制边连通度:当2≤n≤k+1时λ_(2)(P_(n)^(k))=2n-4,当n>k+1时,λ_(2)(P_(n)^(k))=2k-1.

侦诉审“互相制约”的冲突与调适

侦诉审“互相制约”是刑事诉讼的基本原则,包含了侦诉、侦审、诉审三者之间的关系。以审判为中心的诉讼制度改革为侦诉审“互相制约”的重释提供了契机,应摒弃“废除论”“修改论”的观点,从“解释论”的角度为侦诉审“互相制约”注入生机。“互相制约”有其深厚的权力监督理论渊源,需要厘清其与“互相配合”及检察机关“法律监督”之间的关系。当前,侦诉审“互相制约”存在侦诉之间配合程度较高、诉审分离尚未实现、逆向制约机制尚不健全等现实冲突。在以审判为中心的语境下形成审判制约起诉、起诉制约侦查的逆向制约格局,改变过去“平行式”的制约模式。侦诉审“互相制约”的调适,应当以统一的证明标准健全审判逆向制约方式,以检察引导侦查协调审前阶段的制约关系,明确辩护权制约公权力的独特地位。

职务犯罪调查检察制约监督的原则与路径

在监察机关职务犯罪调查中,有效发挥检察机关制约监督职能是实现职务犯罪调查权良性运行的有力保障。检察机关具有制约监督权能,这一权能没有因为监察体制改革的推行而被取代。职务犯罪调查具备侦查要素,与刑事侦查具有相同的客观目的和法律效果,具有接受检察制约监督的该当性。确立以法律监督权和公诉权为根本内容的监督体制,遵循相互制约、适度制约和事后与事中制约相结合的原则,充分发挥公诉、不起诉、退回补充调查、非法证据排除权能加强引导和监督,完善检察建议制度,制约监督职务犯罪调查权的不当行使,实现高效反腐和制度反腐的目的。

分权与制衡:北宋时期国家治理的主线

北宋时期发展出一套与近代责任政府“神似”的独特治理体系,通过非成文法(祖宗法)确立下来的“习惯法”上升成了朝廷纲常——君权象征化,国家治理一旦有过失,则必问责,责任即由宰相们承担。北宋开国便确立了一系列政治原则:(1)“士大夫与皇帝共天下”实则为北宋不可变的政治惯例,“虚君实相”的治理结构使得皇权表现出高度的谦抑性;(2)责任政府让皇帝“统而不治”,治权与政权高度分离,宰相拥有较高的行政权;(3)台谏在北宋的地位极高,对行政权形成了史无前例的限制,形成了皇帝——宰相——台谏的并立局面。

论审判权监督制约体系的再完善

在当前中国的司法实践中,对审判权的监督制约存在责任划分混乱、各类监督体系相对独立、监督制度不健全和监督滞后等问题。针对上述问题,应整合监督力量、强化政法教育和完善配套规章制度,以推进审判权监督制约体系的逐步完善。

涉案企业合规检察权运行制约监督体系建构

稳步规范推进涉案企业合规改革,关乎新时代检察权高质量发展。涉案企业合规检察权运行呈现“检察主导+专业介入”的全新行权模式,在试点探索中还存在该用不用、不该用乱用、监督考察和司法审查流于形式等问题,亟待建构高质效目标导向的制约监督体系,有效解决“纸面合规”“合规腐败”等社会质疑与担忧。在具体路径上,可从分层分阶、诉讼构造和数据赋能等三个维度,探索构建涉案企业合规检察权运行制约监督体系,推动高质效办好每一个合规案件,为建立中国特色现代企业合规司法制度夯实实践基础。

从权力建构视角看中国共产党巡视制度变迁

巡视制度是中国共产党全面从严治党的一项重要制度安排。从巡视制度的内容与功能变迁,可以透视中国共产党权力建构过程的三个阶段:以权力集中为主要任务的第一阶段,以权力制约为主要任务的第二阶段,以建构两者动态平衡为主要任务的第三阶段,最终目标是实现权力运行的动态平衡。巡视制度变迁体现了中国共产党领导下现代国家建构的一般规律。治国必先治党,要实现权力运行的动态平衡,必须从权力建构视角全面认知和贯彻全面从严治党。

论“守门人”制度的嬗变及其对完善我国互联网平台主体责任的启示

作为“守门人”的主体具备对通道的控制力,在相关制度的发展中承担监管辅助者与被监管对象的双重角色。在我国平台责任中应厘清“以网管网”与对超大型平台特殊监管的不同规制逻辑。“以网管网”属第三方执行策略,利用第三方平台的“守门”能力以监管用户的不法行为,在此过程中平台承担着辅助监管者的角色;而特殊义务制度通过对超大型平台课以一系列特殊义务,以约束和引导其私权力的行使,防止其“守门”权力的滥用。我国应在充分利用平台“守门”能力的同时有效避免“守门”权力的滥用,强化超大型平台特殊义务的构建,通过填补相关立法空白、优化“守门人”界定、设置区分性义务、保留规则的灵活性等手段引导平台经济产业的健康发展。
