QZNs: Quantum Z-numbers

Deng, Jixiang; Deng, Yong
Subjects: Computer Science >> Integration Theory of Computer Science

Because of the efficiency of modeling fuzziness and vagueness, Z-number plays an important role in real practice. However, Z-numbers, defined in the real number field, lack the ability to process the quantum information in quantum environment. It is reasonable to generalize Z-number into its quantum counterpart. In this paper, we propose quantum Z-numbers (QZNs), which are the quantum generalization of Z-numbers. In addition, seven basic quantum fuzzy operations of QZNs and their corresponding quantum circuits are presented and illustrated by numerical examples. Moreover, based on QZNs, a novel quantum multi-attributes decision making (MADM) algorithm is proposed and applied in medical diagnosis. The results show that, with the help of quantum computation, the proposed algorithm can make diagnoses correctly and efficiently.

Subjects: Psychology >> Management Psychology

随着行业竞争压力的加剧,工作狂领导在职场中愈发普遍。然而对于工作狂领导在组织中的有效性,无论是在实践界还是在学术界都尚存争议。鉴于此,本研究基于社会信息加工理论,分析工作狂领导对团队绩效的双刃剑作用机制。通过对某物业管理服务公司进行多时点、多来源的问卷调查,研究结果表明:一方面,工作狂领导会提升团队工作卷入,促进团队绩效;另一方面,工作狂领导也会引发团队消极情绪,损害团队绩效表现;团队工作重要性能有效缓解工作狂领导对团队绩效的消极作用,同时促进其积极作用。以上研究发现有助于辨证理解工作狂领导有效性,为组织培育管理**提供有益借鉴。

Subjects: Psychology >> Cognitive Psychology

关于急性应激对攻击行为的影响,现有研究多集中于单次急性应激情境下。然而,相比单次急性应激,对重复暴露于同一应激源的研究更能反映人们在现实生活中经历的应激事件。与单次应激不同,重复性急性应激与应激适应有关,能够节省资源,具有很强的进化和适应意义,但目前关于重复性急性应激对攻击行为的影响却知之甚少。鉴于此,研究运用事件电位相关技术、鼻喷催产素和催产素受体基因型分析方法,探讨重复性急性应激对攻击行为的影响及内部机制,并进一步探讨通过内部和外部调控重复性急性应激反应后攻击行为的变化。

Subjects: Biology >> Biochemistry

心血管疾病是当今世界第一大致死因素,动脉粥样硬化是其重要病理基础,其早期诊断具有重要意义。尿液更利于积累和反应机体生理状态的变化且不受到稳态机制的调节,是疾病早期生物标志物的良好来源。本文通过高脂饮食诱导ApoE-/-小鼠5个月构建动脉粥样硬化动物模型,选取七个时间点收集实验组及正常饮食对照组c57BL/6小鼠尿液样品,使用蛋白质组学分析方法,进行自身对照和组间对照。自身对照结果表明高脂饮食1周前后尿液蛋白质组差异显著,同时多种差异蛋白被报道过与动脉粥样硬化相关或可作为其生物标志物。组间对照结果表明差异蛋白GO分析得出的生物学过程能够对应疾病发生发展的进程。两种对照方式得到的差异性化学修饰也多被报道与该疾病进程相关。实验证明了尿液蛋白质组学有敏锐监测机体变化的潜力,为寻找动脉粥样硬化早期生物标志物提供了可能。

A Hybrid Algorithm for the Equal Districting Problem

Yunfeng Kong
Subjects: Geosciences >> Geography

The equal districting problem (EDP) arises in applications such as political redistricting, police patrol area delineation, sales territory design and some service area design. The important criteria for these problems are district equality, contiguity and compactness. A mixed integer linear programming (MILP) model and a hybrid algorithm are proposed for the EDP. The hybrid algorithm is designed by extending iterative local search (ILS) algorithm with three schemes: population-based ILS, variable neighborhood descent (VND) local search, and set partitioning. The performance of the algorithm was tested on five areas. Experimenta-tion showed that the instances could be solved effectively and efficiently.

老年人的消极交往与心理健康:实证、理论与展望

徐潞杰; 张镇
Subjects: Psychology >> Applied Psychology

积极交往和消极交往分别会对老年人的心理健康产生有利和不利影响,然而,探讨消极交往的负面作用及其机制的研究相对较少。目前研究主要涉及消极交往的类型(社会隔离、丧偶或离婚)、来源(配偶、子女或朋友)及强度,并探讨感知评估、自尊的中介作用及性别、婚姻、受教育水平等变量的调节作用。社会情感选择理论、优劣势整合理论、社会交换理论及镜中我理论在一定范围内对消极交往的负面作用做出了合理解释。采取“原谅”或“认知疏远”的应对策略能有效缓解消极交往的负面影响。未来研究应进一步考察不同文化背景及社会网络背景下消极交往对老年人心理健康的影响,同时加强对消极交往的理论研究和线上研究,并关注相关的干预研究。

“One-to-three” droplet generation-based digital microfluidics for parallel immunoassay.docx

Kai, Jin; Chenxuan, Hu; Siyi, Hu; Jinhua, Li; Hanbin, Ma
Subjects: Biology >> Bioengineering

In digital microfluidics, droplet generation is the fun, as the basis for a series of droplet manipulations including mixing, separation, dispensing, etc., has always been the focus in the field of digital microfluidics. Currently, the performance of DMF-based droplet splitting is highly influenced by the ratio of electrode size and the gap between the upper and lower plates. Here we propose a "one to three" droplet splitting method. In "one to three" spitting method, a pair of opposite electrowetting forces are applied to the droplet. As the electrowetting force is applied on the splitting position, a middle child droplet and two mother liquid droplets generate. The aspect ratio of child droplet is close to 1:2. "One to three" spitting method is then applied to magnetic beads immunoassay. Magnetic beads are retained in child droplets under small magnetic force with high magnetic bead washing efficiency. Simultaneous detection of five B-type natriuretic peptide analyte samples are performed on a single chip within 10 minutes. Correlation coefficient (R2) of the calibration curve was 0.9942, and the detection limit was less than 5pg/mL. This unique method of digital microfluidic droplet splitting has great potential in other application fields.

Bacterial and viral therapies of cancer background, mechanism and perspective

Subjects: Medicine, Pharmacy >> Preclinical Medicine

Bacterial and viral therapies of cancer are highly promising, yet their mechanisms are incompletely understood, hindering their improvement and application. In this paper, We (1) review briefly the genesis and progress of bacterial and viral therapies of cancer, (2) compare and evaluate the proposed mechanisms of bacterial and viral therapies and present the unifying mechanism that bacterial and viral therapies of cancer mainly take advantage of the immune response of cancer cells to bacteria and viruses and the ability of host immune system to recognize and eliminate the responsive cancer cells, and (3) provide a perspective on the exploitation of non-human and non-animal bacteria and viruses, particularly protist-infecting bacteria and viruses and bacterial virus (bacteriophage), for cancer therapy.

心理病理学网络理论、方法与挑战

Subjects: Psychology >> Statistics in Psychology

对于精神障碍这一概念的理解,传统DSM–ICD分类诊断系统和研究领域标准RDoC均基于潜变量视角,认为精神障碍的症状由其潜在共同原因所致。这2种观点都忽略了症状间的相互作用。不同于分类和维度视角,Borsboom在2008年对精神障碍的概念化提出了的全新视角——心理病理学网络理论。此理论的核心观点是症状之间的动态因果关系构成了精神障碍。基于心理病理学网络理论的网络分析方法,主要以结合EBIC的glasso算法估计症状间的偏相关网络,并通过网络中节点中心性与网络连接性等指标,来考查精神障碍症状的不同特性。近几年来,研究者发现心理病理学网络分析方法在对症状间因果关系的推断、核心症状的识别和网络结构的可靠性与可重复性方面仍面临一些挑战。这些挑战为心理病理学网络理论与方法指明了未来可能的发展方向。

Taxonomic revision of the holotype of Proboselaphus watasei Matsumoto, 1915 (Bovidae, Artiodactyla) from Chuanyu area, China

Subjects: Biology >> Zoology

A taxonomic revision of Proboselaphus watasei Matsumoto, 1915 (Bovidae, Artiodactyla) from the Pleistocene of Chuanyu area, China demonstrates that this genus and species names are invalid. The holotype with a skull and mandibles was recently rediscovered in the fossil collection by Nobuo Naora, which is housed in the National Museum of Japanese History, Chiba Prefecture, Japan. Proboselaphus watasei was described as a closely-related species to living nilgai, or Boselaphus tragocamelus, in South Asia, based on general characteristics of pecorans, such as small bony horn-cores and hypsodont cheek teeth. However, the cranial and dental morphologies re-examined in the present study clearly show that the holotype has cervid-specific characteristics: e.g., the fronto-parietal surface curving dorsally, the basioccipital with a triangular outline, and molars with isolated anterior and posterior lobes. The molars of the holotype are comparable to those of Cervus unicolor, in having strong accessary structures (or spurs, cingulums/cingulids, and styles/stylids), and are as large as those of Cervus cf. C. unicolor from the Pleistocene deposits in southern China. This taxonomic change suggests that any crown-boselaphins had not dispersed into East Asia since the Pleistocene.
