Defining Quantum Advantage for Building a Sustainable MVP to Deliver Quantum Computing Services

Quantum Computing (QC) is hailed as the future of computers. After Google’s claim of achieving Quantum Supremacy in 2019, several groups challenged the claim. Some QC experts attribute catastrophic risks that unrestrained QC may cause in the future by collapsing the current cryptographic cybersecurity infrastructure. These predictions are relevant only if QC becomes commercially viable and sustainable in the future. No technology can be a one-way ticket to catastrophe, and neither can the definition of superiority of that technology be. If there are catastrophic risks, large-scale QC can never enter the public domain as a minimum viable product (MVP) unless there are safeguards in place. Those safeguards should obviously become an integral part of the definition of its superiority over the legacy systems. NIST (National Institute of Standards & Technology) is pursuing the standardization of Post Quantum Cryptography (PQC) as that safeguard. However, with all the 82 candidate PQCs failing and companies already offering QC as a service, there’s an urgent need for an alternate strategy to mitigate the impending Q-Day threat and render QC sustainable. Our research proposes a novel encryption-agnostic cybersecurity approach to safeguard QC. It articulates a comprehensive definition of an MVP that can potentially set a sustainable gold standard for defining commercially viable quantum advantage over classical computing.

Evaluation of the Clinical Advantages of Laparoscopic Transverse Abdominal Wall Suspension in the Treatment of Pelvic Organ Prolapse

Objective:To evaluate the clinical advantages of laparoscopic transverse abdominal wall suspension in treating pelvic organ prolapse.Methods:Sixty patients diagnosed with moderate to severe pelvic organ prolapse and underwent surgical treatment in our hospital between January 2022 and December 2023 were selected.According to different surgical methods,they were divided into an observation group(given laparoscopic transverse abdominal wall suspension)and a control group(given transvaginal mesh implantation),with 30 subjects/group.The data on perioperative-related indicators,quality of life scores,postoperative recurrence,and complications of the two groups of patients were collected.Results:The postoperative hospitalization days and intraoperative bleeding volume of the observation group were significantly lower than those of the control group,but had longer operation time than that of the control group(P<0.05).The differences between the two groups were statistically significant 6 months after surgery,and the Pelvic Floor Disease Quality of Life Impact Questionnaire(PFIQ-7)score of the observation group was significantly higher than the control group(P<0.05).Both groups of patients completed 12 months of follow-up without any postoperative recurrence.The number of complications in the observation group was slightly lower than that of the control group(P>0.05).Conclusion:Laparoscopic transverse abdominal wall suspension was more effective in treating pelvic organ prolapse and is an ideal surgical procedure.

Comparative Advantage and Latecomer Advantage

To achieve development,developing countries must capitalize on their relative advantages,including comparative advantage and latecomer advantages.A country must develop an industrial structure that is consistent with the comparative advantage of its factor structure in order to avoid the trap of“structural catch-up”that stifles development.The issue for developing countries is that their comparative advantage in core factors of production is unstable and tends to decrease and dissipate.Such a comparative advantage cannot provide adequate growth for convergence to occur.Developed countries,on the other hand,can sustain economic growth due to their comparative advantage in high-quality factors.Latecomer advantage refers to the ability of developing countries to increase their knowledge factor in a cost-effective manner by learning,importing,assimilating,and using knowledge and technology that already exist.Although comparative and latecomer advantages may have a combined effect,each has its distinct characteristics.Latecomer advantage is a special development factor that applies to latecomers.It is crucial at all stages of development,but especially so in the middle-income stage and beyond.Bringing latecomer advantage into full play is essential for developing nations to converge with the advanced countries.

融合执行力与适应性:基层治理的制度优势分析

基层是国家制度传导的神经末梢,其治理效能的有效发挥是制度优势最直接的体现。新时代十年来,我国各领域基础性制度框架基本建立,但发展不平衡不充分问题仍然突出,信息公开、垃圾分类等基层治理中的制度优势彰显不足。制度优势向治理效能转化是国家治理的应然逻辑,转化过程中的动态机制、信任关系都会影响到制度执行的效果。单纯以制度执行力评判制度优势和治理效能略显偏颇,制度之所以具备优势,在于其能体现公平正义、呼应人之需求。而不同人的利益追求、目标取向、认知结构均不相同,这导致基层治理中制度出现适应性问题。经由理论层面的合理补充与实然层面的动态修复,融合执行力与适应性,有望打通制度优势、运行机制、信任支撑、治理效能的闭合回路,从而加快制度优势向基层传导,并反向以基层治理效能倒逼各类制度优化完善。

本文基于中、美、日、韩近30年在锂电池汽车领域的专利数据,选取20个关键指标构建“技术-经济-法律”三维分析模型,并划分出关键核心专利,在此基础上应用景气综合指数法计算四国在锂电池汽车产业的竞争优势指数,并对其进行比较与分析。结果表明,中、美、日、韩在锂电池汽车领域的总体发展布局已基本到达顶峰,且于近两年呈现波动下降趋势。总体来看,美国获得竞争优势时间最早且指数发展趋势最为稳定,连续多年稳居第一;中国获得竞争优势时间最晚,但指数发展速度最快,截至2021年末,中国总体竞争优势指数与美国持平,远超日、韩两国。分维度来看,中、美分别于经济、技术维度具有绝对竞争优势;韩国在经济、法律维度发展较为稳定,但技术维度影响整体,导致整体呈现波动下降趋势;日本在各维度均呈现出明显下降趋势,仅在技术维度下降幅度较小。由此得出结论:中国经济发展带动整体,已基本实现锂电池汽车产业的技术赶超,技术维度的发展是获得持续性竞争优势的基础,因此应在保持现有锂电池汽车领域竞争优势的同时注重相关技术轨道的跨越与变迁,以获取新能源汽车产业的持续性竞争优势。

数字贸易强国:理论、指标及测度

在数字经济成为全球重要经济形态的背景下,正确认识数字贸易强国必须建立在科学构建数字贸易强国指数的基础上。本文在理论上分析了数字化程度对贸易利益的微观影响机制,据此构建了数字贸易强国综合衡量指标,继而测算了2012—2019年主要经济体的数字贸易强国指数,并从质量、规模等多个维度进行了分解。结果显示:第一,样本期内中国数字贸易强国指数位于世界第二,但在数字贸易质量方面与美国、日本、德国等发达国家仍有较大差距;第二,从产业层面看,中国数字产业领域的数字贸易具有显著优势,保持了领先地位,这源于在全球价值链分工条件下中国数字产成品出口占据了数量和质量优势,但在融合数字技术的传统产业方面数量和质量均不占优;第三,基于产品层面的测算结果表明,在作为数字产业核心的中间产品方面,中国与发达国家有较大差距。建设数字贸易强国,中国亟待由数量优势、产成品优势向质量优势和核心中间产品优势转型。

共享平台的生存空间和社会价值

基于互联网的共享经济迅猛发展,满足了越来越多的社会需求.基于这一背景,首先分析了共享经济的业态、发展阶段以及共享经济的优势和劣势.然后从平台的视角,以“相对综合优势”指标为出发点定义了“市场份额增量指标”,研究共享平台与专业平台同时进入市场竞争和平台分别作为领导者与追随者等不同情形下的竞争情况与均衡状态.最后考察共享平台在市场上的生存空间和社会价值.研究发现:1)若共享平台和专业平台同时进入市场竞争,只有当专业平台相对综合优势足够显著时,共享平台将可能退出市场;否则即使面对专业平台的相对综合优势,共享平台仍然能够生存,出现两类平台相互竞争的局面;而且闲置资源的低回报要求,使得共享平台将专业平台挤出市场变得可能.2)相比同时进入市场竞争,共享平台作为追随者参与竞争的优势更明显,平台具有后发优势.3)从共享平台的社会价值来看,共享平台进入市场不一定增加社会福利,只有当共享平台从社会福利角度出发,达到最优的产出水平时,其进入市场能够补偿专业平台的多样化损失,实现最优补偿.

比较优势视角下我国虚拟水流动归因分析

虚拟水是近年来水资源领域的研究热点,而相关研究成果主要集中于虚拟水转移的规模核算及其特征分析,对虚拟水转移的动力成因较少讨论,所以借助比较优势理论中的区位商、增长商指数,量化解析农林牧渔、工业、建筑业、批发零售、交通运输、住宿餐饮、金融、房地产、其他服务业9大行业的发展优势及增长潜力,并分析这9大行业虚拟水流动格局与行业比较优势的相关关系。研究结果表明:各行业虚拟水流动格局与行业比较优势具有明显关联,2002—2017年间我国72%的虚拟水会从具有比较优势的地区向不具备优势的地区转移,71%的虚拟水转移量会受到行业发展速度影响。研究成果预期可为我国水资源宏观管理及节水政策制定提供理论依据及决策参考。决策参考。

考虑品牌优势的回收商生产模式研究:再制造或翻新

研究品牌优势对回收商生产模式选择的影响机制,并基于三方博弈模型,运用KKT条件等方法分析不同品牌优势下,回收商选择再制造或翻新的决策条件和利益分配结果。结果表明,在品牌优势较低的情况下,回收商的生产模式选择会依赖回收成本。当回收成本较低时,全部翻新是回收商最优策略,但这会损害品牌制造商和品牌零售商的利益;当回收成本适中时,回收商倾向于部分翻新,此时品牌零售商可以从中获益,但品牌制造商会受到冲击;当回收成本较高时,回收商翻新威胁小,品牌制造商和品牌零售商都会默认接受这一结果。在品牌优势较高的情况下,回收商和品牌制造商有动机达成再制造协议,实现双方的共赢,但品牌零售商会极力反对这一协议。此外,合作再制造模式并不一定能带来更高的消费者剩余,在一定条件下,翻新竞争模式下消费者剩余可能会超过合作再制造模式下的水平。

中医药治疗青春期多囊卵巢综合征的现代机制研究进展及优势

多囊卵巢综合征(PCOS)是与内分泌异常、生殖功能障碍关系密切的一种疾病,以雄激素过高、持续无排卵或胰岛素抵抗为重要特征。PCOS多于青春期起病,青春期PCOS患病率逐年升高,发病年龄逐渐提前,患者除了有闭经、肥胖、痤疮、多毛等常见的症状外,还有可能产生焦虑、自卑等心理障碍,这给许多青春期女性带来困扰,应积极地予以临床干预。传统医学认识青春期PCOS注重脏腑,认为本病病机为肾虚,兼以脾虚、肝郁;现代医学的认识则进展为信号通路靶向的细胞进程,主要涉及Wnt/β-catenin、PI3K/Akt/mTOR等信号通路。目前,对于青春期PCOS目前尚无统一标准的诊疗方案,在临床中,除常用的西药治疗外,可以采用中药及中医特色治疗进行积极、及时的干预。本文对青春期PCOS的中医药治疗方法及现代机制研究进展进行综述,以期对青春期PCOS的治疗提供多种途径的治疗方法。

扬长避短:优势使用视角下知识异质性对越轨创新的影响机制研究

有效利用员工优势资源提高竞争力是企业关注的重点,但目前对于如何有效化解组织内非协同性导致的认知冲突尚未给予关注。鉴于此,关注知识异质性的双重属性,结合个体优势使用理论,通过问卷调查的形式收集到381份问卷数据,实证分析知识异质性对越轨创新影响过程中员工优势使用的中介作用以及领导权变激励的边界条件。结果表明:(1)知识异质性能够对越轨创新产生积极影响;(2)员工优势使用在知识异质性与越轨创新之间具有部分中介作用,即知识异质性可以促进员工的优势使用,进而对越轨创新产生积极影响;(3)领导权变激励会强化员工优势使用与越轨创新之间的正向关系,同时正向调节知识异质性通过员工优势使用影响越轨创新的间接效应。据此,提出企业应重视和开发知识异质性员工的价值、重视员工优势的开发,并采取及时有效的领导激励,以充分利用员工差异化知识储备、将员工自身优势转化为创新性成果,使企业能够长期保持核心竞争优势。

结合优势结构和最小目标Q值的深度强化学习导航算法

针对现有基于策略梯度的深度强化学习方法应用于办公室、走廊等室内复杂场景下的机器人导航时,存在训练时间长、学习效率低的问题,本文提出了一种结合优势结构和最小化目标Q值的深度强化学习导航算法.该算法将优势结构引入到基于策略梯度的深度强化学习算法中,以区分同一状态价值下的动作差异,提升学习效率,并且在多目标导航场景中,对状态价值进行单独估计,利用地图信息提供更准确的价值判断.同时,针对离散控制中缓解目标Q值过估计方法在强化学习主流的Actor-Critic框架下难以奏效,设计了基于高斯平滑的最小目标Q值方法,以减小过估计对训练的影响.实验结果表明本文算法能够有效加快学习速率,在单目标、多目标连续导航训练过程中,收敛速度上都优于柔性演员评论家算法(SAC),双延迟深度策略性梯度算法(TD3),深度确定性策略梯度算法(DDPG),并使移动机器人有效远离障碍物,训练得到的导航模型具备较好的泛化能力.
