    最近,量子元胞自动机(QCA)技术已经有了很多研究,因为它保证了低功耗,低复杂度,低延迟,和紧凑的空间。同时,近似算法,一种新的计算模式,简化了计算过程,并以低功耗的形式出现,算法电路的高性能设计方法。此外,XOR门已广泛用于数字设计,并且是可以在许多即将到来的技术中使用的基本构建块。全加器(FA)电路是QCA技术的关键组件,用于算术逻辑运算,包括减法,乘法,和分裂。对近似FA的设计进行了大量的研究,全减法器(FS),全加法器/减法器(FA/S),和基于XOR逻辑的4位纹波进位加法器(RCA),将它们作为创建基于QCA的算术电路的必要组件。本研究提出了三种新的有效的基于QCA的电路,基于XOR逻辑:近似FA,近似FS,近似FA/S,和近似4位纹波进位加法器(RCA)。有趣的是,有些设计的一侧有输入,另一侧有输出,使其更容易到达的组件,而不会被其他细胞包围,并导致更有效的电路设计。特别是,0.5个时钟相位的延迟,0.01μm2的面积,并且在近似FA和减法器设计中实现仅利用11个单元。同样,估计的FA/S设计显示0.5时钟相位延迟,0.01μm2面积,和用于实现的12个单元格。提出了使用64个QCA单元的近似4位RCA。这些设计的有效性通过QCADesigner程序的功能验证进行评估。根据仿真结果,这些提出的解决方案不仅功能良好,而且在速度和空间方面明显优于以前的想法。拟议的FA,FS,RCA设计比以前的最佳设计高出21%,21%,43%,分别,在细胞计数方面。
    Recently, there has been a lot of research in Quantum Cellular Automata (QCA) technology because it promises low power consumption, low complexity, low latency, and compact space. Simultaneously, approximate arithmetic, a new paradigm in computing, streamlines the computational process and emerges as a low-power, high-performance design approach for arithmetic circuits. Furthermore, the XOR gate has been widely used in digital design and is a basic building block that can be used in many upcoming technologies. The full adder (FA) circuit is a key component of QCA technology and is utilized in arithmetic logic operations including subtraction, multiplication, and division. A great deal of research has been done on the design of approximate FA, full subtractor (FS), full adder/subtractor (FA/S), and 4-bit ripple carry adder (RCA) based on XOR logic, establishing them as essential components in the creation of QCA-based arithmetic circuits. This study presents three new and effective QCA-based circuits, based on XOR logic: an approximate FA, an approximate FS, an approximate FA/S, and an approximate 4-bit ripple carry adder (RCA). Interestingly, some designs have inputs on one side and outputs on the other, making it easier to reach the components without being encircled by other cells and leading to a more effective circuit design. In particular, a delay of 0.5 clock phases, an area of 0.01 μm2, and implementation utilizing just 11 cells was accomplished in the approximate FA and subtractor designs. In a similar vein, the estimated FA/S designs showed 0.5 clock phase delay, 0.01 μm2 area, and 12 cells used for implementation. An approximate 4-bit RCA is proposed using 64 QCA cells. The effectiveness of these designs is evaluated through functional verification with the QCADesigner program. According to simulation results, these proposed solutions not only function well but significantly outperform previous ideas in terms of speed and space. The proposed FA, FS, and RCA designs surpassed the previous best designs by 21%, 21%, and 43%, respectively, in terms of cell count.

    模式意识对于自动驾驶汽车的安全使用很重要,然而,驾驶员对模式转换的理解尚未得到充分调查。在这项研究中,我们对838名受访者进行了一项在线调查,以检查他们对部分和有条件驾驶自动化中控制责任的理解,其中包括四种类型的干预措施(制动踏板,方向盘,油门踏板,和接管请求)。结果表明,大多数驾驶员了解他们负责制动踏板干预后的速度和距离控制以及方向盘干预后的转向控制。然而,驾驶员对方向盘干预后的速度和距离控制责任以及油门踏板干预后的转向控制责任的反应不一。具有更高的自动化水平(有条件的驾驶自动化),与较低的自动化水平(部分驾驶自动化)相比,驾驶员希望自动化更经常地保持责任。关于动手要求,超过99%的受访者回答说,在部分自动化的所有干预类型之后,司机会把手放在方向盘上,而60-95%的人会在有条件自动化的各种干预类型后将手放在方向盘上。通过将调查响应与商用部分自动化车辆的模式转换逻辑进行比较,可以观察到实际逻辑与驾驶员对控制责任的期望之间的偏差。为了解决控制责任的混乱,并确保一致的期望,我们建议实施一致的模式设计,并为驾驶员提供增强的信息。
    Mode awareness is important for the safe use of automated vehicles, yet drivers\' understanding of mode transitions has not been sufficiently investigated. In this study, we administered an online survey to 838 respondents to examine their understanding of control responsibilities in partial and conditional driving automation with four types of interventions (brake pedal, steering wheel, gas pedal, and take-over request). Results show that most drivers understand that they are responsible for speed and distance control after brake pedal interventions and steering control after steering wheel interventions. However, drivers have mixed responses regarding the responsibility for speed and distance control after steering wheel interventions and the responsibility for steering control after gas pedal interventions. With a higher automation level (conditional driving automation), drivers expect automation to remain responsible more often compared to a lower automation level (partial driving automation). Regarding Hands-on requirements, more than 99% of respondents answered that drivers would keep their hands on the steering wheel after all intervention types in partial automation, while 60-95% would place their hands on the wheel after various intervention types in conditional automation. A misalignment between actual logic and drivers\' expectations regarding control responsibilities is observed by comparing survey responses to the mode transition logic of commercial partially automated vehicles. To resolve confusion about control responsibilities and ensure consistent expectations, we propose implementing a consistent mode design and providing enhanced information to drivers.

    背景:逻辑模型以图形方式呈现各种“程序”的社会技术组成部分,例如教育程序。它们显示了程序应该如何工作的基本逻辑和假设。我们建议它们可用于描述复杂的社会技术卫生IT干预措施的机制。
    目的:评估逻辑模型描述健康IT因果链的适用性。
    结果:我们目前正在对患者门户对患者预后的影响进行综合审查。我们从找到的出版物中提取了以下逻辑模型元素:资源,活动,输出,结果,和影响。然后使用这些因素来填充逻辑模型并形成证据的结构化图形表示。直到现在,我们发现的所有证据都可以融入逻辑模型。逻辑模型能够容纳各种类型的证据。
    结论:逻辑模型似乎适合代表健康IT影响的证据。
    BACKGROUND: Logic models graphically present the socio-technical components of a variety of \'programs\' such as educational programs. They show the underlying logic and assumptions of how a program is supposed to work. We suggest that they can be used to describe the mechanisms of complex socio-technical health IT interventions.
    OBJECTIVE: To assess the suitability of logic models to describe cause-effect chains of health IT.
    RESULTS: We are currently conducting an integrative review of the impact of patient portals on patient outcomes. We extracted the following elements of logic models from the found publications: resources, activities, output, outcome, and impact. These factors are then used to populate the logic model and form a structured graphical representation of the evidence. Until now, all the evidence we found could be fit into the logic model. The logic model was able to accommodate diverse types of evidence.
    CONCLUSIONS: Logic models seem to be suitable for representing evidence on the impact of health IT.

    量化模态推断兴趣逻辑学家,语言学家,和计算机科学家,但是文献中似乎没有对它们进行心理学研究。这里有一个例子:所有这些艺术家都是商人。保罗可能是艺术家之一。接下来是什么?人们倾向于得出结论:保罗可能是一个商人(实验1)。这似乎是合理的,它遵循一个直观的心理模型,其中保罗是一组艺术家谁是商人之一。进一步的审议可以产生一个替代可能性的模型,其中保罗不是艺术家之一,这证实了结论只是一种可能性。障碍是标准的模态逻辑,处理可能性,不能对任何前提得出特定的结论:无限多(从任何前提)有效地遵循,但它们不包括本结论。然而,进一步的实验证实了一种新的心理模型理论对各种推论的预测(实验2),从关于可能性的前提得出的事实结论的发生(实验3)和从模态三段论的前提得出的推论(实验4)。因此,这个理论是合理的,但是我们探索了基于模态逻辑修改的认知理论的可行性。
    Quantified modal inferences interest logicians, linguists, and computer scientists, but no previous psychological study of them appears to be in the literature. Here is an example of one: All those artists are businessmen. Paulo is possibly one of the artists. What follows? People tend to conclude: Paulo is possibly a businessman (Experiment 1). It seems plausible, and it follows from an intuitive mental model in which Paulo is one of a set of artists who are businessmen. Further deliberation can yield a model of an alternative possibility in which Paulo is not one of the artists, which confirms that the conclusion is only a possibility. The snag is that standard modal logics, which deal with possibilities, cannot yield a particular conclusion to any premises: Infinitely many follow validly (from any premises) but they do not include the present conclusion. Yet, further experiments corroborated a new mental model theory\'s predictions for various inferences (Experiment 2), for the occurrence of factual conclusions drawn from premises about possibilities (Experiment 3) and for inferences from premises of modal syllogisms (Experiment 4). The theory is therefore plausible, but we explore the feasibility of a cognitive theory based on modifications to modal logic.

    到目前为止,生物计算严格遵循数字电子的传统设计原则,当组装更复杂的基因电路时,它可能会达到极限。这里,通过创建三态缓冲区的遗传变异,而不是使用传统的逻辑门作为基本信号处理单元,我们引入了基于三态的逻辑合成(TriLoS)框架,用于资源高效地设计多层基因网络,能够在单细胞群体中执行复杂的布尔演算。这为简单的,模块化,以及各种感兴趣的算术逻辑的低干扰映射,以及单个细胞内有效扩大的工程空间。我们不仅构建了在细胞水平上运行全加器和全减器操作的计算基因网络,而且还描述了基于可编程细胞疗法的治疗范式。允许在体内可调节和疾病特异性的药物分泌逻辑。这项工作可以促进现代生物计算机的发展,朝着精密医学中尚未开发的应用发展。
    So far, biocomputation strictly follows traditional design principles of digital electronics, which could reach their limits when assembling gene circuits of higher complexity. Here, by creating genetic variants of tristate buffers instead of using conventional logic gates as basic signal processing units, we introduce a tristate-based logic synthesis (TriLoS) framework for resource-efficient design of multi-layered gene networks capable of performing complex Boolean calculus within single-cell populations. This sets the stage for simple, modular, and low-interference mapping of various arithmetic logics of interest and an effectively enlarged engineering space within single cells. We not only construct computational gene networks running full adder and full subtractor operations at a cellular level but also describe a treatment paradigm building on programmable cell-based therapeutics, allowing for adjustable and disease-specific drug secretion logics in vivo. This work could foster the evolution of modern biocomputers to progress toward unexplored applications in precision medicine.

    任何实验带来的结果和结论必然具有不确定性。许多因素影响这种不确定性的程度,然而,当从研究机构中得出结论时,它们可能会被忽视。这里,我们展示了如何将主观逻辑用作荟萃分析的补充工具,以将所选的不确定性来源纳入研究人员寻求提供的答案中。我们通过关注已经进行荟萃分析的研究来说明这种方法,其总体目标是评估人类婴儿是否更喜欢亲社会代理人而不是反社会代理人。我们展示了如何将每个发现编码为主观意见,以及如何将发现汇总以产生明确包含不确定性的答案。我们认为,这种方法的核心特征和优势在于其在考虑不确定性和推理研究结果的过程中的透明度。主观逻辑有望成为一种强大的补充工具,可以在研究评估中明确和透明地纳入不确定性。
    Any experiment brings about results and conclusions that necessarily have a component of uncertainty. Many factors influence the degree of this uncertainty, yet they can be overlooked when drawing conclusions from a body of research. Here, we showcase how subjective logic could be employed as a complementary tool to meta-analysis to incorporate the chosen sources of uncertainty into the answer that researchers seek to provide to their research question. We illustrate this approach by focusing on a body of research already meta-analyzed, whose overall aim was to assess if human infants prefer prosocial agents over antisocial agents. We show how each finding can be encoded as a subjective opinion, and how findings can be aggregated to produce an answer that explicitly incorporates uncertainty. We argue that a core feature and strength of this approach is its transparency in the process of factoring in uncertainty and reasoning about research findings. Subjective logic promises to be a powerful complementary tool to incorporate uncertainty explicitly and transparently in the evaluation of research.

    人们对制造可以检测和去除水污染物的设备非常感兴趣,特别是废水中的重金属离子和染料,促进可持续用水。在这项研究中,用硼砂叶提取物(BoF-LE)合成银纳米粒子(BoF-AgNPs),与BoF-LE作为还原剂和封端剂。通过与对照样品和其他活性金属离子的比较,测试了BoF-AgNPs对Mn(II)离子的灵敏度和选择性。我们的结果表明,BoF-AgNPs在检测Mn(II)离子方面具有极高的灵敏度和选择性,检测限为0.3ppb。HR-TEM,紫外-可见光谱,和DLS研究用于确认BoF-AgNP通过基于聚集的机制检测Mn(II)离子。此外,发现BoF-AgNPs对MB染料的快速脱色有效,如它们在7分钟内将MB脱色92.66%的能力所证明的。本研究首次报道了BoF-AgNPs的成功合成及其两种应用。使用抑制与逻辑门启用。使用BoF-AgNPs检测和降解水污染物可以促进可持续用水。
    There is great interest in fabricating devices that can detect and remove water pollutants, especially heavy metal ions and dyes from wastewater, to promote sustainable water use. In this study, an extract of Borassus flabellifer leaves (BoF-LE) was used to synthesize silver nanoparticles (BoF-AgNPs), with the BoF-LE serving as a reducing and capping agent. The sensitivity and selectivity of BoF-AgNPs for Mn(II) ions were tested by comparing with the control sample and other competent metal ions. Our results showed that BoF-AgNPs are extremely sensitive and selective in detecting Mn(II) ions, with a detection limit of 0.3 ppb. HR-TEM, UV-Vis spectroscopy, and DLS investigations were used to confirm that BoF-AgNPs detect Mn(II) ions by an aggregation-based mechanism. Additionally, it was found that BoF-AgNPs are effective in rapidly decolorizing MB dye, as demonstrated by their ability to decolorize MB by 92.66% within 7 min. This study is the first to report successful synthesis of BoF-AgNPs and their two applications, which are enabled with an Inhibit-AND logic gate. Using BoF-AgNPs to detect and degrade water pollutants may promote sustainable water use.

    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.
