    碳基同素异形体正在推动通信技术革命,传感,和计算,同时挑战上个世纪的基本理论。然而,对先进碳基材料的需求仍然很大。其症结在于高效、靠得住的新型碳同素异形体工程。虽然C18已经经历了长时间的理论和实验研究,它的制备和在凝聚阶段的直接观察直到最近才通过STM/AFM技术发生。独特的环状环结构和双18中心π离域特性为C18引入了各种不常见的性质,使其成为值得深入探索的课题。在这种情况下,这篇综述深入研究了过去的发展,有助于对C18的最新理解,并提供了对未来努力如何加快实际应用的见解。包括广谱,这篇综述全面调查了C18的几乎所有方面,包括几何特征,电子离域,粘结性质,芳香性,反应性,电子激励,紫外/可见光谱,分子间相互作用,对外部字段的响应,电子亲和力,电离,和其他分子特性。此外,该综述还概述了使用原子操作技术直接合成和表征C18的代表性策略。在此之后,总结了基于C18的复合物,以及在催化中的潜在应用,电化学装置,光电子学,和传感进行了讨论。
    Carbon-based allotropes are propelling a technological revolution in communication, sensing, and computing, concurrently challenging fundamental theories of the previous century. Nevertheless, the demand for advanced carbon-based materials remains substantial. The crux lies in the efficient and reliable engineering of novel carbon allotrope. Although C18 has undergone theoretical and experimental investigation for an extended period, its preparation and direct observation in the condensed phase occurred only recently through STM/AFM techniques. The distinctive cyclic ring structure and the dual 18-center π delocalization character introduce various uncommon properties to C18, rendering it a subject worthy of in-depth exploration. In this context, this review delves into past developments contributing to the state-of-the-art understanding of C18 and provides insights into how future endeavours can expedite practical applications. Encompassing a broad spectrum, this review comprehensively investigates almost all facets of C18, including geometric characteristics, electron delocalization, bonding nature, aromaticity, reactivity, electronic excitation, UV/Vis spectrum, intermolecular interaction, response to external fields, electron affinity, ionization, and other molecular properties. Moreover, the review also outlines representative strategies for the direct synthesis and characterization of C18 using atom manipulation techniques. Following this, C18-based complexes are summarized, and potential applications in catalysis, electrochemical devices, optoelectronics, and sensing are discussed.

    背景:在一氧化碳中毒后迟发性脑病(DEACMP)的治疗中,使用依达拉奉(EDA)和高压氧疗法(HBOT)越来越普遍。这项荟萃分析旨在评估使用EDA和HBOT联合单独使用HBOT治疗DEACMP的疗效。
    方法:我们从中国和美国的12个中英文数据库和临床试验中心检索并纳入了2023年11月6日之前发表的所有随机对照试验(RCT)。主要结果指标为总有效率。次要结果指标包括迷你精神状态检查(MMSE),蒙特利尔认知评估(MoCA)美国国立卫生研究院卒中量表(NIHSS),Barthel指数(BI),长谷川痴呆量表(HDS),Fugl-Meyer评估(FMA),超氧化物歧化酶(SOD),和丙二醛(MDA)。使用的统计措施包括风险比率(RR),加权平均差(WMD),和95%置信区间(95%CI)。
    结果:最终纳入了30项涉及2075名参与者的研究。观察到EDA与HBOT联合治疗DEACMP显示总有效率改善(RR:1.25;95%CI:1.20-1.31;P<0.01),MMSE(WMD:3.67;95%CI:2.59-4.76;P<0.01),MoCA(WMD:4.38;95%CI:4.00-4.76;P<0.01),BI(WMD:10.94;95%CI:5.23-16.66;P<0.01),HDS(WMD:6.80;95%CI:4.05-9.55;P<0.01),FMA(WMD:8.91;95%CI:7.22-10.60;P<0.01),SOD(WMD:18.45;95%CI:16.93-19.98;P<0.01);NIHSS(WMD:-4.12;95%CI:-4.93至-3.30;P<0.01)和MDA(WMD:-3.05;95%CI:-3.43至-2.68;P<0.01)降低。
    结论:低质量证据表明,对于DEACMP,与单独使用HBOT相比,结合使用EDA和HBOT可能与更好的认知和日常生活活动有关。在未来,进行更精心设计的多中心和大样本RCT来证实我们的结论是至关重要的。
    BACKGROUND: The use of both edaravone (EDA) and hyperbaric oxygen therapy (HBOT) is increasingly prevalent in the treatment of delayed encephalopathy after carbon monoxide poisoning (DEACMP). This meta-analysis aims to evaluate the efficacy of using EDA and HBOT in combination with HBOT alone in the treatment of DEACMP.
    METHODS: We searched and included all randomized controlled trials (RCTs) published before November 6, 2023, from 12 Chinese and English databases and clinical trial centers in China and the United States. The main outcome indicator was the total effective rate. The secondary outcome indicators included the Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), National Institutes of Health Stroke Scale (NIHSS), Barthel Index (BI), Hasegawa Dementia Scale (HDS), Fugl-Meyer Assessment (FMA), Superoxide Dismutase (SOD), and Malondialdehyde (MDA). Statistical measures utilized include risk ratios (RR), weighted mean difference (WMD), and 95 % confidence intervals (95 % CI).
    RESULTS: Thirty studies involving a combined total of 2075 participants were ultimately incorporated. It was observed that the combination of EDA with HBOT for the treatment of DEACMP demonstrated an improvement in the total effective rate (RR: 1.25; 95 % CI: 1.20-1.31; P < 0.01), MMSE (WMD: 3.67; 95 % CI: 2.59-4.76; P < 0.01), MoCA (WMD: 4.38; 95 % CI: 4.00-4.76; P < 0.01), BI (WMD: 10.94; 95 % CI: 5.23-16.66; P < 0.01), HDS (WMD: 6.80; 95 % CI: 4.05-9.55; P < 0.01), FMA (WMD: 8.91; 95 % CI: 7.22-10.60; P < 0.01), SOD (WMD: 18.45; 95 % CI: 16.93-19.98; P < 0.01); and a reduction in NIHSS (WMD: -4.12; 95 % CI: -4.93 to -3.30; P < 0.01) and MDA (WMD: -3.05; 95 % CI: -3.43 to -2.68; P < 0.01).
    CONCLUSIONS: Low-quality evidence suggests that for DEACMP, compared to using HBOT alone, the combined use of EDA and HBOT may be associated with better cognition and activity of daily living. In the future, conducting more meticulously designed multicenter and large-sample RCTs to substantiate our conclusions is essential.

    目的:本研究旨在根据人体工程学(运动学)和生理学(皮肤电活动-EDA,血压和体温)外科医生的参数来自他们在微创机器人手术活动的先前即时情况下收集的记录。
    方法:为此,在由11名具有不同经验水平的外科医生完成的26次机器人辅助外科手术中,收集了与外科医生的人体工程学和生理参数相关的数据.一旦数据集生成,应用了两种预处理技术(缩放和归一化),这两个数据集分为两个子集:80%的数据用于训练和交叉验证,和20%的数据用于测试。三种预测技术(多元线性回归-MLR,支持向量机-SVM和多层感知器-MLP)应用于训练数据集以生成预测模型。最后,这些模型在交叉验证和测试数据集上进行了验证.每次会议结束后,外科医生被要求完成对他们的压力感觉的调查。将这些数据与使用预测模型获得的数据进行比较。
    结果:结果表明,MLR与缩放预处理相结合,对于所分析的每个参数,R2系数最高,误差最低。此外,外科医生的调查结果与预测模型的结果高度相关(R2=0.8253).
    结论:本研究中提出的线性模型在交叉验证和测试数据集上成功验证。这一事实证明了预测因素的可能性,这些因素有助于我们在机器人手术期间改善外科医生的健康。
    OBJECTIVE: This study aims predicting the stress level based on the ergonomic (kinematic) and physiological (electrodermal activity-EDA, blood pressure and body temperature) parameters of the surgeon from their records collected in the previously immediate situation of a minimally invasive robotic surgery activity.
    METHODS: For this purpose, data related to the surgeon\'s ergonomic and physiological parameters were collected during twenty-six robotic-assisted surgical sessions completed by eleven surgeons with different experience levels. Once the dataset was generated, two preprocessing techniques were applied (scaled and normalized), these two datasets were divided into two subsets: with 80% of data for training and cross-validation, and 20% of data for test. Three predictive techniques (multiple linear regression-MLR, support vector machine-SVM and multilayer perceptron-MLP) were applied on training dataset to generate predictive models. Finally, these models were validated on cross-validation and test datasets. After each session, surgeons were asked to complete a survey of their feeling of stress. These data were compared with those obtained using predictive models.
    RESULTS: The results showed that MLR combined with the scaled preprocessing achieved the highest R2 coefficient and the lowest error for each parameter analyzed. Additionally, the results for the surgeons\' surveys were highly correlated to the results obtained by the predictive models (R2 = 0.8253).
    CONCLUSIONS: The linear models proposed in this study were successfully validated on cross-validation and test datasets. This fact demonstrates the possibility of predicting factors that help us to improve the surgeon\'s health during robotic surgery.

    少汗症外胚层发育不良(HED)是一种影响外胚层起源结构的遗传性疾病,比如牙齿,头发,和汗腺。与常染色体隐性和显性遗传方式相比,X-连锁HED(XLHED)的特点是缺牙症/少牙症,没有/稀疏的头发,多汗症/多汗症,和特征性的面部特征,是最常见的,其主要原因是外生体异常蛋白A(EDA)基因的突变。本研究旨在阐述中国男性XLHED的临床和分子特征,并总结和比较先前的一些发现。
    基因组DNA是从先证者及其家庭成员的外周血中获得的,然后使用Sanger测序进行EDA的突变分析。采用实时定量PCR和Western印迹法检测EDA的表达。使用荧光素酶测定法检测NF-κB的转录活性。
    具有XLHED的先证者被鉴定为新的EDA突变,c.1119G>C(p。M373I),影响了跨膜蛋白外显子8突变的分子分析,继承自母亲。他表现出严重的多颗牙齿脱落,缺少20多颗恒牙,头发和眉毛稀疏,干,薄,皮肤瘙痒。此外,他的出汗功能在一定程度上是异常的。
    功能研究表明,这种新型突变体导致NF-κB的EDA表达水平和转录活性显着降低。我们的发现扩展了XLHED患者中EDA突变的范围,为进一步探讨XLHED的发病机制提供了依据和思路。
    UNASSIGNED: Hypohidrotic ectodermal dysplasia (HED) is a genetic disorder that influences structures of ectodermal origin, such as teeth, hair, and sweat glands. Compared with autosomal recessive and dominant modes of inheritance, the X-linked HED (XLHED) characterized by Hypodontia/Oligodontia teeth, Absent/sparse hair, Anhidrosis/hypohidrosis, and characteristic facial features, is the most frequent and its primary cause is the mutation of ectodysplasin A (EDA) gene. This research aimed to expound the clinical and molecular features of a Chinese male with XLHED and to summarize and compare several previous findings.
    UNASSIGNED: Genomic DNA was obtained from the peripheral blood of the proband and his family members, then Sanger sequencing was used to perform a mutational analysis of EDA. Real-time quantitative PCR and Western blotting were used to detect EDA expression. The transcriptional activity of NF-κB was detected using a luciferase assay.
    UNASSIGNED: The probandwith XLHED was identified a novel EDA mutation, c.1119G>C(p.M373I), that affected the molecular analysis of transmembrane protein exon8 mutations, inherited from the mother. He showed a severe multiple-tooth loss, with over 20 permanent teeth missing and sparse hair and eyebrows, dry, thin, and itching skin. Furthermore, his sweating function was abnormal to a certain extent.
    UNASSIGNED: The functional study showed that this novel mutant led to a significant decrease in the EDA expression level and transcriptional activity of NF-κB. Our findings extend the range of EDA mutations in XLHED patients, which provides the basis and idea for further exploring the pathogenesis of XLHED.

    在大自然中度过时光,甚至观看自然的图像或视频,对一个人的精神状态有积极的影响。然而,认知紧张的工作通常在室内进行,在休息时无法轻松接近大自然的办公室。在这项研究中,我们调查了观看一段5分钟的视听视频是否有助于恢复认知压力后的精神状态,该视频描述了在森林小径上的第一人称视角步行。参与者被要求执行认知应激源任务,之后,他们展示了一个自然漫步视频或控制视频。主观恢复使用视频前后的自我报告进行测量,同时在视频观看期间测量皮肤电活动(EDA)和脑电图(EEG)。结果表明,体验自然行走视频比观看控制视频更能增强主观恢复。自主神经系统的觉醒,使用EDA测量,在自然行走视频期间比在控制视频期间减少更多。此外,在自然行走视频期间,EEG的上theta波段(6-8Hz)和下alpha波段(8-10Hz)的活动增加,这表明它引起了一种放松的心态。有趣的是,参与者与自然的联系缓和了自然视频的影响。主观和生理指标都表明,观看短片,模拟自然散步可能有利于放松精神和恢复认知压力后的精神状态。
    Spending time in nature, and even watching images or videos of nature, has positive effects on one\'s mental state. However, cognitively stressful work is often performed indoors, in offices that lack easy access to nature during breaks. In this study, we investigated whether watching a 5-min audiovisual video that describes a first-person perspective walk on a forest path could help to restore one\'s mental state after cognitive stress. Participants were asked to perform cognitive stressor tasks, after which they were shown either a nature walk video or a control video. Subjective restoration was measured using self-reports before and after the videos, while electrodermal activity (EDA) and electroencephalography (EEG) were measured during the video-watching session. The results showed that experiencing the nature walk video enhanced subjective restoration more than watching the control video. Arousal of the autonomic nervous system, measured using EDA, decreased more during the nature walk video than during the control video. Additionally, activity in the EEG\'s upper theta band (6-8 Hz) and lower alpha band (8-10 Hz) increased during the nature walk video, suggesting that it induced a relaxed state of mind. Interestingly, the participants\' connection with nature moderated the effects of the nature video. The subjective and physiological measures both suggest that watching a short, simulated nature walk may be beneficial in relaxing the mind and restoring one\'s mental state after cognitive stress.

    This data paper presents a unique multimodal dataset collected from a comprehensive experiment using a wheelchair training simulator. The dataset consists of quantitative and qualitative data that represents the user\'s experience and performance. Participants engaged in a series of navigational tasks in a simulated environment under two distinct system configuration conditions: a. a conventional monitor display and b. a virtual reality (VR) headset. The monitor group has a total of 24 participants data while using the simulator with a standard display and then other two groups of 18 and 16 respectively using the VR headset with a different wheelchair\'s speed profile. It was collected data from total of 58 participants. The dataset includes physiological data - Heart Rate Variability (HRV), Electrodermal Activity (EDA), Acceleration (ACC), Skin Temperature, Heart Rate (HR), and Blood Volume Pulse (BVP) - collected during both experiments. Additionally, for the standard display condition, more detailed data comprising Electroencephalography (EEG) and eye-tracking metrics were recorded to provide insights into cognitive load and visual attention patterns. System metrics captured from the simulator provide an objective performance report, including task completion times, error rates (collision of the virtual wheelchair), number of joystick commands. Also, the navigation efficiency data is complemented by post-experiment questionnaires, which gathered subjective responses on user experience, perceived difficulty, the user immersive levels, arousal, and simulator sickness symptoms. This dataset is valuable for researchers and practitioners in the fields of assistive technology, human-computer interaction, and rehabilitation. It offers metrics to a comprehensive view of how different display technologies influence the user experience in wheelchair simulation training. The data allows for in-depth analysis of physiological responses, cognitive engagement, and subjective perceptions, providing a foundation for future research on effective wheelchair training methodologies and the potential benefits of VR in rehabilitation settings.

    根据多重唤醒理论,皮肤电活动(EDA)在整个身体是不均匀的。然而,左或右EDA优势的心理含义仍然不清楚。我们探索了EDA横向不对称性,将其作为关于飞镖比赛中成功和失败的乐观和悲观归因风格的心理生理标志。由ObimonEDA测量了230个竞争对的双边EDA模式,包括运动的加速度计测量。首先,我们证实,基于来自两个手腕的EDA数据,可以可靠地测量侧向不对称性.第二,我们基于80次个人投掷评估了与横向不对称相关的归因风格.我们记录了参与者对他们即将到来的表现的期望,以及他们对成功和失败的归因,基于塞利格曼对乐观主义者的定义(归因于成功的内部原因,或归因于失败的外部原因)或悲观主义者。对于具有右侧或左侧EDA优势的投掷,乐观主义者和悲观主义者归因的比率显着不同(p=0.001)。乐观归因的特征是84%的权利占主导地位,而悲观主义者在罚球过程中占63%的左占优势的EDA。我们在另外10个人的50次投掷中复制了这些发现(p=0.034)。每个人都是右撇子。我们得出的结论是,在身体运动过程中可以可靠地测量手腕EDA,例如在飞镖游戏中。横向EDA不对称性是在竞争环境中对成功和失败的态度的一致心理生理标志,这表明情绪唤醒的横向不对称性可能是一种新的归因方式的心理生理生物标志物。结果是双侧唤醒评估的心理生理相关性的基础,并为多重唤醒理论提供了基于证据的验证。
    According to the Multiple Arousal Theory, electrodermal activity (EDA) is not uniform across the body. However, the psychological meaning of a left or right-sided EDA dominance is still not clear. We explored EDA lateral asymmetry as a psychophysiological marker of optimistic and pessimistic attributional style regarding success and failure in a darts competition. Bilateral EDA pattern of 230 throws of a competing pair was measured by Obimon EDA including accelerometer measurements of movements. First, we confirmed that lateral asymmetry can be measured reliably based on EDA data from both wrists. Second, we assessed attributional styles related to lateral asymmetry based on 80 individual throws. We recorded participants\' expectations regarding their upcoming performance, and their attribution of success and failure based on Seligman\'s definition as optimist (internal cause attributed to success, or external cause ascribed to failure) or pessimist. The ratio of optimist and pessimist attributions was significantly different for throws with right or left-sided EDA dominance (p = 0.001). Optimistic attribution characterized 84% of right dominant, while pessimist 63% of left-dominant EDA during throws. We replicated these findings on 50 throws from 10 more individuals (p = 0.034). All individuals were right-handed. We conclude that wrist EDA can be reliably measured during physical movements, such as in a darts game. Lateral EDA asymmetry is a consistent psychophysiological marker of the attitude toward success and failure in a competitive setting, suggesting that lateral asymmetry of emotional arousal may serve as a novel psychophysiological biomarker for attribution style. Results underlie the psychophysiological relevance of bilateral arousal assessment and provide evidence-based verification for the Multiple Arousal Theory.

    目标:尽管有令人震惊的证据表明对妇女的性暴力,人们对男性对强奸的情绪反应以及这些可能如何参与性暴力动态知之甚少。因此,我们的目的是捕捉如何在情感上评估强奸场景。方法:本研究评估了男性(N=30)的自我报告和心理生理情绪反应(面部肌电图,皮肤电活动)到强奸现场,并将其与他们对描绘非性暴力和非暴力男女互动的刺激的反应进行了对比。男人的情绪反应和他们对强奸神话的认可之间的联系,个性,还检查了性特征。结果:研究结果表明,强奸现场导致更高的负面影响,主观上和通过增加的面部肌电图(瓦楞纸板活动)索引,比其他两个刺激。此外,神经质的人格特质,较低的宜人性,较低的意识,精神病倾向,以及较低的性抑制倾向,都与强奸的主观性唤起有关。结论:研究结果增加了有关推定情感过程的文献,这些情感过程是对妇女的性暴力评估的基础。
    Objective: Despite alarming evidence on sexual violence against women, little is known about men\'s emotional responses to rape and how these may be involved in sexual violence dynamics. Accordingly, our aim was to capture how rape scenarios are emotionally appraised. Methods: The current study evaluated men\'s (N = 30) self-reported and psychophysiological emotional responses (facial EMG, electrodermal activity) to a rape scene, and contrasted it with their responses to stimuli depicting nonsexual violence and nonviolent male-female interactions. The associations between men\'s emotional responses and their endorsement of rape myths, personality, and sexual traits were also examined. Results: Findings revealed that the rape scene resulted in higher negative affect, both subjectively and indexed by increased facial EMG (corrugator activity), than the other two stimuli. Additionally, personality traits of neuroticism, lower agreeableness, lower consciousness, psychopathic tendencies, as well as lower sexual inhibition proneness, were all associated with higher subjective sexual arousal toward rape. Conclusions: Findings add to the literature on the putative emotional processes underpinning the appraisal of sexual violence against women.

    催眠,一种历史悠久的治疗方法,在解决一系列心理和躯体疾病方面的有效性已获得广泛认可。虽然它的主要作用是由自上而下的中央机制介导的,催眠还通过调节自主神经系统(ANS)发挥外周影响。心理生理措施,如心率(HR)及其变异性(HRV),皮肤电活动(EDA),呼吸频率(RR),和镇痛伤害性指数(ANI),作为ANS活性的可靠指标。研究一直证明催眠能力显着影响ANS功能,降低交感神经活动,增强副交感神经张力。这种效果在放松过程中特别明显,并且受到催眠能力和任务条件等中介因素的影响。尽管方法上有局限性,这篇综述强调了通过催眠增强ANS调制的潜力,包括它与中枢神经系统(CNS)的连接,优化与ANS功能障碍相关的心身疾病患者的治疗结果。
    Hypnosis, a time-honored therapeutic approach, has gained widespread recognition for its effectiveness in addressing a range of psychological and somatic disorders. While its primary effects are mediated by central top-down mechanisms, hypnosis also exerts peripheral influence by modulating the autonomic nervous system (ANS). Psychophysiological measures, such as heart rate (HR) and its variability (HRV), electrodermal activity (EDA), respiratory rate (RR), and the analgesia nociceptive index (ANI), serve as reliable indicators of ANS activity. Studies have consistently demonstrated hypnosis\' ability to significantly impact ANS functions, lowering sympathetic activity and enhancing parasympathetic tone. This effect is particularly pronounced during relaxation procedures and is influenced by mediating factors like hypnotizability and task conditions. Despite methodological limitations, this review highlights the potential of enhanced ANS modulation through hypnosis, including its connections to the central nervous system (CNS), to optimize therapeutic outcomes in patients with psychosomatic disorders associated with ANS dysfunction.

    虚拟现实暴露疗法是一种认知行为疗法的方法,通过使疗法切实可行和具有成本效益来帮助治疗焦虑症。它还允许通过使用客观,持续的反馈。这种反馈可以使用生物传感器来获得,以收集生理信息,例如心率,皮肤电活动和额叶大脑活动。作为开发我们客观反馈框架的一部分,我们开发了一个虚拟现实适应完善的情感Stroop颜色字任务。我们使用这种适应来区分三种不同的焦虑水平:没有焦虑,轻度焦虑和严重焦虑。我们对年龄在18至65岁之间的29名参与者进行了环境测试。在分析和验证此环境之后,我们使用它创建了一个数据集,用于对指定的焦虑水平进行进一步的机器学习分类.要实时应用这些信息,我们所有的信息都是在虚拟现实中处理的。我们的卷积神经网络能够使用留一交叉验证以75%的准确率区分焦虑水平。这表明我们的系统可以准确区分不同的焦虑水平。
    Virtual Reality Exposure Therapy is a method of cognitive behavioural therapy that aids in the treatment of anxiety disorders by making therapy practical and cost-efficient. It also allows for the seamless tailoring of the therapy by using objective, continuous feedback. This feedback can be obtained using biosensors to collect physiological information such as heart rate, electrodermal activity and frontal brain activity. As part of developing our objective feedback framework, we developed a Virtual Reality adaptation of the well-established emotional Stroop Colour-Word Task. We used this adaptation to differentiate three distinct levels of anxiety: no anxiety, mild anxiety and severe anxiety. We tested our environment on twenty-nine participants between the ages of eighteen and sixty-five. After analysing and validating this environment, we used it to create a dataset for further machine-learning classification of the assigned anxiety levels. To apply this information in real-time, all of our information was processed within Virtual Reality. Our Convolutional Neural Network was able to differentiate the anxiety levels with a 75% accuracy using leave-one-out cross-validation. This shows that our system can accurately differentiate between different anxiety levels.
