    人们倾向于更喜欢逻辑上有效的结论而不是无效的结论的发现在文献中被称为逻辑喜欢效应,并且传统上被解释为所谓逻辑直觉概念的证据。最近调查条件三段论和分类三段论的实证研究的结果表明,然而,逻辑喜欢效应的先前实例可以通过表面特征气氛的混淆来解释。但是,到目前为止,这种大气效应的真正性质在很大程度上仍然难以捉摸。这里,我们解决了这个问题,并介绍了析取三段论的两种变体,使我们能够解解有效性,结论的可能性,和表面特征大气,这在早期研究中使用简单的析取三段论是不可能的。三个实验,参与者被要求提供这些论点的喜好和逻辑评级,揭示了析取三段论中的逻辑喜欢效应可以通过一种气氛与隐含的需求相结合来解释,以在判断讨人喜欢时考虑逻辑性。我们还观察到逻辑评级中的强烈气氛效应超出了逻辑有效性本身的影响。此外,大气效应似乎仅由特定的表面特征引起,即那些在生态上有效的,如果容易犯错,逻辑性的预测因子。我们得出的结论是,获得的气氛启发式方法为逻辑有效性提供了代理,而推理者通常会从表面上看。将当前结果与以前的实验结果进行比较,这些实验集中在条件三段论和分类三段论上,还表明无论参数的复杂性如何,都使用了这些大气启发法。
    The finding that people tend to prefer logically valid conclusions over invalid ones is known in the literature as the logic-liking effect and has traditionally been interpreted as evidence for the notion of so-called logical intuitions. Results of more recent empirical studies investigating conditional and categorical syllogisms suggest, however, that previous instances of the logic-liking effect can be accounted for by a confound in terms of surface-feature atmosphere. But the true nature of this atmosphere effect has so far remained largely elusive. Here, we address this issue and introduce two variants of disjunctive syllogisms that enable us to deconfound validity, possibility of the conclusion, and surface-feature atmosphere, which has been impossible with simple disjunctive syllogisms used in earlier studies. Three experiments, in which participants were asked to provide liking and logic ratings for these arguments, revealed that the logic-liking effect in disjunctive syllogisms can be explained by an atmosphere confound in combination with implied demand to consider logicality when judging likability. We also observed a strong atmosphere effect in logic ratings over and above an effect of logical validity per se. Furthermore, atmosphere effects appear to be induced only by specific surface features, namely those that are ecologically valid, if fallible, predictors for logicality. We conclude that acquired atmosphere heuristics provide proxies for logical validity that reasoners often take at face value. A comparison of the present results with previous findings from experiments that focused on conditional and categorical syllogisms additionally indicates that these atmosphere heuristics are used irrespective of an argument\'s complexity.

    推理是智能系统的关键能力。大型语言模型(LM)在抽象推理任务上实现了高于偶然的性能,但表现出许多缺陷。然而,人类的抽象推理也是不完善的。人类的推理受到我们现实世界的知识和信念的影响,并显示值得注意的“内容效果”;当问题的语义内容支持正确的逻辑推断时,人类推理更可靠。这些内容纠缠的推理模式是关于人类智力基本性质的辩论的核心。这里,我们研究语言模型-其先前的期望捕获人类知识的某些方面-是否类似地将内容混合到他们对逻辑问题的答案中。我们在三个逻辑推理任务中探索了这个问题:自然语言推理,判断三段论的逻辑有效性,和Wason选择任务。我们评估最先进的LMs,和人类一样,并发现LMs在这些任务上反映了许多相同的定性人类模式,例如人类,当任务的语义内容支持逻辑推断时,模型会更准确地回答。这些相似之处反映在准确性模式中,以及一些较低级别的特征,例如LM对可能答案的置信度与人类响应时间之间的关系。然而,在某些情况下,人类和模型的行为不同,特别是在Wason任务上,人类的表现比大型模型差得多,并表现出明显的错误模式。我们的发现对理解这些人类认知效应的可能贡献者有意义,以及影响语言模型性能的因素。
    reasoning is a key ability for an intelligent system. Large language models (LMs) achieve above-chance performance on abstract reasoning tasks but exhibit many imperfections. However, human abstract reasoning is also imperfect. Human reasoning is affected by our real-world knowledge and beliefs, and shows notable \"content effects\"; humans reason more reliably when the semantic content of a problem supports the correct logical inferences. These content-entangled reasoning patterns are central to debates about the fundamental nature of human intelligence. Here, we investigate whether language models-whose prior expectations capture some aspects of human knowledge-similarly mix content into their answers to logic problems. We explored this question across three logical reasoning tasks: natural language inference, judging the logical validity of syllogisms, and the Wason selection task. We evaluate state of the art LMs, as well as humans, and find that the LMs reflect many of the same qualitative human patterns on these tasks-like humans, models answer more accurately when the semantic content of a task supports the logical inferences. These parallels are reflected in accuracy patterns, and in some lower-level features like the relationship between LM confidence over possible answers and human response times. However, in some cases the humans and models behave differently-particularly on the Wason task, where humans perform much worse than large models, and exhibit a distinct error pattern. Our findings have implications for understanding possible contributors to these human cognitive effects, as well as the factors that influence language model performance.

    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.

    肿瘤的发生往往与多种肿瘤标志物密切相关,因此发展多目标检测方法具有重要意义。通过对DNA逻辑门的输入信号和逻辑运算的适当设计,可以实现不同阶段癌症的检测和诊断。例如,在早期阶段,特定的输入信号可以设计为对应于早期特定的肿瘤标志物,从而实现癌症的早期检测。在后期阶段,用于多目标检测的逻辑门可以设计为同时检测多个生物标志物,以提高诊断的准确性和全面性。在这项工作中,我们构建了一个双目标触发的DNA逻辑门,用于锚定DNA四面体,其中亚甲基蓝嵌入DNA四面体中以敏化ZnO@CdS@Au,实现对目标物质的超灵敏检测。我们测试了AND和OR逻辑门对平台的响应。对于AND逻辑门,传感平台仅在两种miRNA都存在时才响应。在10aM至10nM的浓度范围内,光电信号随着靶浓度的增加而逐渐增加。随后,我们使用OR逻辑门进行miRNA检测。即使只有一个目标存在,传感平台表现出优异的性能。同样,在10aM至10nM的浓度范围内,光电信号随着靶浓度的增加而逐渐增加。最低检测限为1.10aM。无论是需要同时检测多个目标还是只检测其中一个目标,我们可以通过选择合适的逻辑门来实现它。该策略在生物传感等领域具有广阔的应用前景。医学诊断,和环境监测。
    The occurrence of cancer is often closely related to multiple tumor markers, so it is important to develop multitarget detection methods. By the proper design of the input signals and logical operations of DNA logic gates, detection and diagnosis of cancer at different stages can be achieved. For example, in the early stages, specific input signals can be designed to correspond to early specific tumor markers, thereby achieving early cancer detection. In the late stage, logic gates for multitarget detection can be designed to simultaneously detect multiple biomarkers to improve diagnostic accuracy and comprehensiveness. In this work, we constructed a dual-target-triggered DNA logic gate for anchoring DNA tetrahedra, where methylene blue was embedded in the DNA tetrahedra to sensitize ZnO@CdS@Au, achieving ultrasensitive detection of the target substance. We tested the response of AND and OR logic gates to the platform. For AND logic gates, the sensing platform only responds when both miRNAs are present. In the concentration range of 10 aM to 10 nM, the photoelectric signal gradually increases with an increase of the target concentration. Subsequently, we used OR logic gates for miRNA detection. Even if only one target exists, the sensing platform exhibits excellent performance. Similarly, within the concentration range of 10 aM to 10 nM, the photoelectric signal gradually increases with an increase of the target concentration. The minimum detection limit is 1.10 aM. Whether it is the need to detect multiple targets simultaneously or only one of them, we can achieve it by selecting the appropriate logic gate. This strategy holds promising application prospects in fields such as biosensing, medical diagnosis, and environmental monitoring.

    CRISPR-Cas系统为广泛的应用提供了一种通用的RNA指导方法。由于RNA合成生物学的进步,引导RNA(gRNA)的工程化使得能够条件控制CRISPR-Cas系统。然而,实现CRISPR-Cas系统的精确调节以有效调节内部代谢过程仍然具有挑战性。在这项工作中,我们开发了一个强大的dCas9调控因子,该调控因子具有工程化的条件gRNA,以实现对内源基因的严格控制。我们在大肠杆菌中的条件gRNA可以通过与触发RNA的特异性相互作用来控制基因表达,其动态范围高达130倍,评估一个三输入逻辑A或(B和C)。条件gRNA介导的内源性代谢基因靶向,lacz,malt和poxB,通过代谢通量控制引起大肠杆菌生长的差异调节。Further,条件gRNAs可以调节必需的细胞骨架基因,ftsZ和mreB,控制细胞成丝和分裂。最后,三种类型的双输入逻辑门可以用于FTZ调节的条件控制,导致形态变化。基于可编程RNA相互作用的条件gRNA的成功操作和应用表明,我们的系统可以与其他Cas效应子兼容,并在其他宿主生物体中实施。
    The CRISPR-Cas system provides a versatile RNA-guided approach for a broad range of applications. Thanks to advances in RNA synthetic biology, the engineering of guide RNAs (gRNAs) has enabled the conditional control of the CRISPR-Cas system. However, achieving precise regulation of the CRISPR-Cas system for efficient modulation of internal metabolic processes remains challenging. In this work, we developed a robust dCas9 regulator with engineered conditional gRNAs to enable tight control of endogenous genes. Our conditional gRNAs in Escherichia coli can control gene expression upon specific interaction with trigger RNAs with a dynamic range as high as 130-fold, evaluating up to a three-input logic A OR (B AND C). The conditional gRNA-mediated targeting of endogenous metabolic genes, lacZ, malT and poxB, caused differential regulation of growth in Escherichia coli via metabolic flux control. Further, conditional gRNAs could regulate essential cytoskeleton genes, ftsZ and mreB, to control cell filamentation and division. Finally, three types of two-input logic gates could be applied for the conditional control of ftsZ regulation, resulting in morphological changes. The successful operation and application of conditional gRNAs based on programmable RNA interactions suggests that our system could be compatible with other Cas-effectors and implemented in other host organisms.

    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.
