    孩子们在成长过程中被学习的机会包围着(他们社区的语言,他们身体的运动,其他人的偏好和精神生活,游戏,社会规范,等。).这里,我们发现幼儿(N=36;年龄范围2.3-3.2岁)依赖于逻辑推理策略,析取推理(即,A或B,A被排除在外,因此,B),在各种情况下,在他们接受过任何正规的教育或有表达逻辑意义的词语的丰富经验之前。在学习新单词时,学习一个人的新事实,找到比赛的胜利者,幼儿在决定谁必须是赢家之前,系统地考虑和拒绝竞争对手。这表明,幼儿可能有一个通用的逻辑推理工具,他们可以在任何情况下使用。
    Children grow up surrounded by opportunities to learn (the language of their community, the movements of their body, other people\'s preferences and mental lives, games, social norms, etc.). Here, we find that toddlers (N = 36; age range 2.3-3.2 years) rely on a logical reasoning strategy, Disjunctive Inference (i.e., A OR B, A is ruled out, THEREFORE, B), across a variety of situations, all before they have any formal education or extensive experience with words for expressing logical meanings. In learning new words, learning new facts about a person, and finding the winner of a race, toddlers systematically consider and reject competitors before deciding who must be the winner. This suggests that toddlers may have a general-purpose logical reasoning tool that they can use in any situation.

    分析过去二十年中国一票否决制度的演变特征和内在逻辑,在考虑改革和标准化时具有非常重要的意义。为了进行这种分析,利用Nvivo12软件对福建颁发的一票否决相关政策文本进行审查,湖北,和甘肃省。通过对关键词频率统计的比较分析,政策文本形式,和三个省的内容特点,人们发现,经过20年的发展,政府部门对一票否决制度的利用经历了根本变化。这些变化主要体现在对政策文本中一票否决的描述的完善,逐步减少一票否决的退出机制,扩大了一票否决的应用领域。
    Analyzing the evolutionary features and internal logic of the one-vote veto system in China over the past two decades is highly significant when considering reform and standardization. In order to conduct this analysis, the Nvivo 12 software was used to examine policy texts related to the one-vote veto issued by Fujian, Hubei, and Gansu provinces. Through a comparative analysis of keyword frequency statistics, policy text form, and content characteristics across the three provinces, it was discovered that governmental departments have experienced fundamental changes in their utilization of the one-vote veto system after 20 years of development. These changes are primarily seen in the refinement of the description of the one-vote veto in policy texts, the gradual reduction in the withdrawal mechanism of the one-vote veto, and an expanded application field for the one-vote veto.

    自旋电子学,利用电子的电荷和自旋,受益于非波动性,低开关能量,和集体磁化行为。这些特性允许磁阻随机存取存储器的发展,磁性隧道结(MTJ)起着核心作用。还广泛探索了各种自旋逻辑概念。其中,基于磁畴壁(DW)运动的自旋逻辑器件使得能够实现紧凑且节能的逻辑电路。在这些设备中,磁轨内的DW运动使自旋信息处理成为可能,而输入和输出的MTJ用作电子写入和读取元件。DW逻辑有望通过在单个器件内执行多个功能来简化逻辑电路复杂性。然而,仍需要演示具有纳米级电子写入和读取功能的DW逻辑电路,以揭示其实际应用潜力。在这次审查中,我们讨论了高速DW运动的材料进步,DW逻辑器件的进展,电流驱动的DW逻辑的开创性演示,及其实际应用的潜力。此外,我们讨论了无电流信息传播的替代方法,以及DW逻辑发展的挑战和前景。
    Spintronics, utilizing both the charge and spin of electrons, benefits from the nonvolatility, low switching energy, and collective behavior of magnetization. These properties allow the development of magnetoresistive random access memories, with magnetic tunnel junctions (MTJs) playing a central role. Various spin logic concepts are also extensively explored. Among these, spin logic devices based on the motion of magnetic domain walls (DWs) enable the implementation of compact and energy-efficient logic circuits. In these devices, DW motion within a magnetic track enables spin information processing, while MTJs at the input and output serve as electrical writing and reading elements. DW logic holds promise for simplifying logic circuit complexity by performing multiple functions within a single device. Nevertheless, the demonstration of DW logic circuits with electrical writing and reading at the nanoscale is still needed to unveil their practical application potential. In this review, we discuss material advancements for high-speed DW motion, progress in DW logic devices, groundbreaking demonstrations of current-driven DW logic, and its potential for practical applications. Additionally, we discuss alternative approaches for current-free information propagation, along with challenges and prospects for the development of DW logic.

    背景:中国特色社会主义进入新阶段。社会主要矛盾是城乡发展不平衡。乡村振兴战略应运而生。乡村振兴的实现,不仅需要发展打基础,更需要治理引领农村发展。发展和治理是乡村振兴不可或缺的两个方面。然而,中国农村长期处于无治理的发展状态,这种情况必须改变。因此,系统探索发展与治理的关系是解决当前农村不足的关键。
    方法:根据统计年鉴的数据,构建了一套乡村发展治理与振兴的评价指标,并验证了模型的有效性。采用熵值法和评价模型计算农村发展综合得分,治理,和振兴。使用耦合协调模型分析了农村发展与治理之间的关系。运用回归分析模型探讨了农村发展耦合结果与农村发展的关系,治理,和乡村振兴。
    结果:从综合结果来看,发展和治理都呈上升趋势,但是向上的发展趋势更好。从发展与治理的耦合协调分析,C值处于良好状态,T值波动剧烈,D随着T的波动而波动,从乡村振兴的综合得分来看,它也显示出逐年上升的趋势。从耦合协调度与乡村振兴综合得分的回归分析结果来看,耦合协调度将显著影响乡村振兴评估值。
    结论:研究发现,当前农村发展与治理呈现螺旋耦合协调关系,耦合协调度与乡村振兴显著相关。根据研究结论,研究进一步提出了促进发展与治理耦合协调的三条路径。第一个是组织同构,构建了农村发展与治理耦合协调体系。二是倾斜资源,提高农村发展治理的衔接要素供给。三是优化农村发展与治理耦合协调路径的运行机制。
    BACKGROUND: Socialism with Chinese characteristics has entered a new stage. The principal social contradiction is the uneven development of urban and rural areas. The rural revitalization strategy has emerged as time has required. The realization of rural revitalization not only requires development to lay the foundation of the countryside but also requires governance to lead the development of the countryside. Development and governance are two indispensable aspects of rural revitalization. However, China\'s rural areas have long been in a state of development without governance, and this situation must change. Therefore, systematically exploring the relationship between development and governance is the key to solving the current shortcomings in rural areas.
    METHODS: Based on the data from the statistical yearbook, the study constructed a set of evaluation indicators for rural development governance and revitalization and verified the model\'s effectiveness.The entropy method and the assessment model were used to calculate the comprehensive score of rural development, governance, and revitalization. The relationship between rural development and governance was analyzed using a coupled coordination model. The regression analysis model was used to explore the relationship between the coupling results of rural development, governance, and rural revitalization.
    RESULTS: From the comprehensive results, both development and governance show an upward trend, but the upward trend of development is better. From the analysis of coupling coordination between development and governance, the C value is in good condition, the T value fluctuates wildly, and the D fluctuates with the fluctuation of T. Judging from the comprehensive score of rural revitalization, it also shows an upward trend year by year. Judging from the regression analysis results of coupling coordination degree and rural revitalization comprehensive score, coupling coordination degree will significantly impact the rural revitalization evaluation value.
    CONCLUSIONS: The study found that current rural development and governance present a spiral coupling coordination relationship, and the degree of coupling coordination significantly correlates with rural revitalization. Based on the research conclusions, the study further proposes three paths to promote the coupling and coordination of development and governance. The first is an organizational isomorphism, which builds a coupled coordination system for rural development and governance. The second is to tilt resources and improve the supply of connected and coordinated factors for rural development and governance. The third is the operating mechanism to optimize rural development and governance\'s coupling and coordination path.

    信息,作为最难以捉摸的主题,是所有思想形式的核心,治理,经济结构,科学,和社会。信息监管,尤其是在医疗保健领域,在全球范围内被证明是一项艰巨的任务,鉴于缺乏定性框架和对信息(或数据)本身的概念和属性的理解。总体定性框架的介绍,包括对信息的定性分析,数据,和知识,将是有价值的,对划定监管有很大帮助,伦理,和战略轨迹。此外,这个框架提供了关于(1)数据隐私和保护的见解(和答案);(2)信息之间的划分,数据,和基于信任的重要概念的知识;(3)建立开放社会和制度的必要条件的结构化方法,保持这种开放性,基于卡尔·波普尔和乔治·威廉·弗里德里希·黑格尔的工作;(4)促进自治和自由并保护开放社会的积极代理方法;(5)基于弗里德里希·哈耶克的工作的数据治理机制,构建了当前的法律-道德-金融和社会社会。这对于有关权利和义务的范围的问题是有见地的,生物体和自由的程度,以及分布式网络系统中的关系结构。这个框架提供了巨大的价值;此外,它提供了关于学术文化的批判性见解和想法(并揭示了它们之间的相互作用),政治,科学,社会,和社会衰败。请注意,根据这份手稿中表达的想法,例如结合个人经验(从而弥补康德和笛卡尔差距),将使用第一人称视角,在相关的地方。
    Information, as the most elusive subject, is central to all forms of thought, governance, economic structure, science, and society. Regulation of information, especially within the healthcare field, is proving to be a difficult task globally, given the lack of a qualitative framework and understanding of the concept and properties of information (or data) itself. The presentation of the overall qualitative framework, comprising a qualitative analysis of information, data, and knowledge, will be valuable and of great assistance in delineating regulatory, ethical, and strategic trajectories. In addition, this framework provides insights (and answers) regarding (1) data privacy and protection; (2) delineations between information, data, and knowledge based on the important notion of trust; (3) a structured approach to establishing the necessary conditions for an open society and system, and the maintenance of said openness, based on the work of Karl Popper and Georg Wilhelm Friedrich Hegel; (4) an active agent approach that promotes autonomy and freedom and protects the open society; and (5) a data governance mechanism based on the work of Friedrich Hayek, which structures the current legal-ethical-financial and social society. This is insightful for questions relating to the extent of rights and duties, the extent of biological bodies and freedom, and the structure of relations in distributed networked systems. There is great value offered in this framework; furthermore, it provides critical insights and thoughts about (and uncovers the interplay between) academic culture, politics, science, society, and societal decay. Note that, in line with the ideas expressed in this manuscript, such as incorporation of personal experience (thereby mending the Kantian and Cartesian gap), a first-person perspective will be used, where relevant.

    布尔网络为描述基因调控网络(GRN)的相互作用和动力学提供了一种有效的机制。得出GRN的准确布尔描述是一项具有挑战性的任务。实验的数量通常比基因的数量少得多。此外,二值化导致信息丢失,二值化时间序列数据出现不一致。仅从二值化时间序列数据推断布尔网络通常会导致复杂和过度拟合的模型。为了获得基因调控网络的相关布尔模型,推理方法可以在一般网络结构和/或精确交互方面结合来自多个来源的数据和先验知识。我们提出了布尔网络推理方法SAILoR(逻辑规则的结构感知推理)。SAILoR将时间序列基因表达数据与提供的参考网络相结合,以推断准确的布尔模型。SAILoR自动从参考网络中提取拓扑属性。这些可以描述GRN的更一般的结构,或者可以更精确地描述特定的相互作用。SAILoR通过从连续和二值化时间序列数据中学习来推断布尔网络。它在两个主要目标之间导航,与参考网络的拓扑相似性以及与基因表达数据的对应关系。通过结合NSGA-II多目标遗传算法,SAILoR依靠人群的智慧。我们的结果表明,SAILoR可以从静态和动态的角度推断GRN的准确且生物学相关的布尔描述。我们表明,与网络推理方法dynGENIE3相比,SAILoR提高了推断网络的静态准确性。此外,我们比较了SAILoR与其他布尔网络推断方法的性能,包括最佳拟合,REVEAL,MIBNI,GABNI,ATEN,和LogBTF。我们已经证明,通过结合有关整体网络结构的先验知识,SAILoR可以在保持动态准确性的同时提高推断布尔网络的结构正确性。为了证明SAILoR的适用性,我们推断了交配前后雌性果蝇的上下文特定的布尔子网络。
    Boolean networks provide an effective mechanism for describing interactions and dynamics of gene regulatory networks (GRNs). Deriving accurate Boolean descriptions of GRNs is a challenging task. The number of experiments is usually much smaller than the number of genes. In addition, binarization leads to a loss of information and inconsistencies arise in binarized time-series data. The inference of Boolean networks from binarized time-series data alone often leads to complex and overfitted models. To obtain relevant Boolean models of gene regulatory networks, inference methods could incorporate data from multiple sources and prior knowledge in terms of general network structure and/or exact interactions. We propose the Boolean network inference method SAILoR (Structure-Aware Inference of Logic Rules). SAILoR incorporates time-series gene expression data in combination with provided reference networks to infer accurate Boolean models. SAILoR automatically extracts topological properties from reference networks. These can describe a more general structure of the GRN or can be more precise and describe specific interactions. SAILoR infers a Boolean network by learning from both continuous and binarized time-series data. It navigates between two main objectives, topological similarity to reference networks and correspondence with gene expression data. By incorporating the NSGA-II multi-objective genetic algorithm, SAILoR relies on the wisdom of crowds. Our results indicate that SAILoR can infer accurate and biologically relevant Boolean descriptions of GRNs from both a static and a dynamic perspective. We show that SAILoR improves the static accuracy of the inferred network compared to the network inference method dynGENIE3. Furthermore, we compared the performance of SAILoR with other Boolean network inference approaches including Best-Fit, REVEAL, MIBNI, GABNI, ATEN, and LogBTF. We have shown that by incorporating prior knowledge about the overall network structure, SAILoR can improve the structural correctness of the inferred Boolean networks while maintaining dynamic accuracy. To demonstrate the applicability of SAILoR, we inferred context-specific Boolean subnetworks of female Drosophila melanogaster before and after mating.

    机器学习(ML)工具在许多不同的医疗环境中的发展正在大幅增加。然而,在日常医疗实践中使用由此产生的算法仍然是一个尚未解决的挑战。我们提出了一种认识论方法(即,基于逻辑原则)在临床实践中应用计算工具。我们依靠科学推理的分类为演绎,感应,以及将ML工具的特征与循证医学[EBM]和经验医学的特征进行比较,作为众所周知的知识生成方法的范例。虽然我们以肝移植为例说明我们的论点,这种方法可以应用于专业的其他方面。关于EBM,它产生了临床医生演绎应用的一般知识,但不能保证其结论的确定性。相比之下,自动算法主要依靠归纳推理。它们的设计可以集成大量数据集,并减轻人类感应中固有的情感偏见。然而,其弱的推断能力(人类临床经验固有的逻辑机制)限制了其在以不确定性为特征的临床环境中的表现,数据是异构的,结果受上下文影响很大,或者预后因素会迅速变化。
    The development of machine learning (ML) tools in many different medical settings is largely increasing. However, the use of the resulting algorithms in daily medical practice is still an unsolved challenge. We propose an epistemological approach (i.e., based on logical principles) to the application of computational tools in clinical practice. We rely on the classification of scientific inference into deductive, inductive, and abductive comparing the characteristics of ML tools with those derived from evidence-based medicine [EBM] and experience-based medicine, as paradigms of well-known methods for generation of knowledge. While we illustrate our arguments using liver transplantation as an example, this approach can be applied to other aspects of the specialty. Regarding EBM, it generates general knowledge that clinicians apply deductively, but the certainty of its conclusions is not guaranteed. In contrast, automatic algorithms primarily rely on inductive reasoning. Their design enables the integration of vast datasets and mitigates the emotional biases inherent in human induction. However, its poor capacity for abductive inference (a logical mechanism inherent to human clinical experience) constrains its performance in clinical settings characterized by uncertainty, where data are heterogeneous, results are highly influenced by context, or where prognostic factors can change rapidly.

    CRISPR/Cas的革命性技术重塑了分子生物学和分子工程的格局。这个工具是感兴趣的研究人员在多个领域,包括分子诊断,分子生物化学回路,和信息存储。随着CRISPR/Cas传播到更多的利基领域,新的应用场景和需求出现。开发CRISPR/Cas的可编程性和兼容性成为新阶段的关键问题。这里,我们报道了一个基于冗余的模块化CRISPR/Cas12a协同激活平台(MCSAP).位置,长度,分裂DNA激活剂中冗余的浓度可以很好地调节Cas12a的活性。以冗余结构作为接口,MCSAP用作模块化插件,可与上游分子网络无缝集成。MCSAP成功执行三个不同的任务:核酸检测,酶检测,和逻辑运算。由于其兼容性和可编程性,MCSAP可以用作不同分子网络的效应物。我们的平台为DNA纳米技术领域提供了强大而易于使用的工具和策略,分子工程,和分子生物学。
    The revolutionary technology of CRISPR/Cas has reshaped the landscape of molecular biology and molecular engineering. This tool is of interest to researchers in multiple fields, including molecular diagnostics, molecular biochemistry circuits, and information storage. As CRISPR/Cas spreads to more niche areas, new application scenarios and requirements emerge. Developing programmability and compatibility of CRISPR/Cas becomes a critical issue in the new phase. Here, we report a redundancy-based modular CRISPR/Cas12a synergistic activation platform (MCSAP). The position, length, and concentration of the redundancy in the split DNA activators can finely regulate the activity of Cas12a. With the redundant structure as an interface, MCSAP serves as a modular plug-in to seamlessly integrate with the upstream molecular network. MCSAP successfully performs three different tasks: nucleic acid detection, enzyme detection, and logic operation. MCSAP can work as an effector for different molecular networks because of its compatibility and programmability. Our platform provides powerful yet easy-to-use tools and strategies for the fields of DNA nanotechnology, molecular engineering, and molecular biology.

    MicroRNA(miRNA)和嘌呤/嘧啶核酸内切酶1(APE1)与癌症密切相关。使它们成为潜在的关键生物标志物和治疗靶标。然而,单一目标的检测不利于疾病的诊断和预后评估。在这项研究中,开发了一种基于AND逻辑门的双锁发夹介导的催化发夹组装(DL-CHA),用于敏感和特异性检测microRNA和APE1。通过在每个发夹上增加一个锁,以APE1和microRNA作为密钥,只有在APE1和miRNA-224同时刺激的情况下才能检测到荧光信号。这表明生物传感器可以作为AND逻辑门操作。DL-CHA具有低背景等优点,快速反应,和高逻辑能力。因此,生物传感器作为癌症诊断的新方法,具有重要的潜在应用。
    MicroRNA (miRNA) and apurinic/apyrimidinic endonuclease 1 (APE1) have been reported to be closely associated with cancers, making them potential crucial biomarkers and therapeutic targets. However, focusing on the detection of a single target is not conducive to the diagnosis and prognosis assessment of diseases. In this study, an AND logic-gate-based dual-locking hairpin-mediated catalytic hairpin assembly (DL-CHA) was developed for sensitive and specific detection of microRNA and APE1. By addition of a lock to each of the hairpins, with APE1 and microRNA serving as keys, fluorescence signals could only be detected in the presence of simultaneous stimulation by APE1 and miRNA-224. This indicated that the biosensor could operate as an AND logic gate. DL-CHA exhibited advantages such as a low background, rapid response, and high logic capability. Therefore, the biosensor serves as a novel approach to cancer diagnosis with significant potential applications.
