The flow-driven piezo-catalysis has been enhanced under visible light due to injection of hot electrons.

Despite the pervasiveness of service robots in hospitality industry, it is unclear how highly human-like service robots elicit aversive effect on consumers’ use intention in addition to discomfort and when the aversive effect can be mitigated. Three experimental studies were conducted, showing that highly human-like service robots elicit greater consumer discomfort and decrease task attraction toward robots, in turn weakening consumers’ use interaction. Moreover, this research identified that emotional-social tasks (vs. mechanical tasks) mitigated the aversive effects of highly human-like service robots on consumers’ responses. The research extends the uncanny valley and mind perception theories and offers some guidelines for employing service robots with different degree of anthropomorphism.尽管服务机器人在酒店业中非常普遍, 但尚不清楚除了不适之外,类似人类的服务机器人在多大程度上会对消费者的使用意图产生厌恶效应, 以及厌恶效应何时可以缓解. 进行了三项实验研究, 结果表明, 高度人性化的服务机器人会引起消费者更大的不适感, 降低对机器人的任务吸引力, 进而削弱消费者的使用互动. 此外, 这项研究还发现, 情感社交任务, 与机械任务相比, 减轻了高度人性化的服务机器人对消费者反应的厌恶效应. 这项研究扩展了神秘谷和心智感知理论, 并为使用具有不同程度拟人化的服务机器人提供了一些指导.

Warning signs play a very important role in safeguarding life and property in dangerous situations. Previous studies have mainly focused on the physical properties of warning signs, and few studies have been conducted on the different types. Methods. In Experiment 1, the oddball paradigm and the go/no-go paradigm were used to study the warning effect of different types of warning signs. In Experiment 2, the dual-task paradigm was adopted. Results. In Experiment 1, the results showed that a warning sign with text as content had the worst warning effect, followed by the combination of image and text, and a warning sign with an image as content had the best warning effect. In Experiment 2, it was found that different types of warning signs would have different effects on the performance of the secondary task. Conclusions. The reason for this may be the different processing methods used for text and image. Therefore, in dangerous situations that require a quick response, simple and understandable graphics should be used as the content of warning signs. In complex circumstances, it may be necessary to use a combination of image and text for warning sign content.

The target article presented a plausible argument that females' susceptibility to threats might be self-protection for staying alive, but some evidence requires scrutiny. We need to consider (1) the biases of narrative reviews, (2) subjective life quality, and (3) the shadow side of extreme reactions to threats before concluding that females' threat-based response is a self-protection mechanism that promotes survival.

Mental and Physical Health outcomes of Mindfulness: An Umbrella Review of Meta-Analyses

Our research questions relate to (1) the cross-cultural differences refer to individual Covid-19 protective behaviours (e.g., wear a face mask, keep physical distance from others, keep personal hygiene and wash hands frequently, and avoid going out), along with their intentions to engage in each of these behaviours. And (2) the potential relationships between those behaviours and individuals’ beliefs (i.e., self-construal, free will and determinism) during the Covid-19 pandemic.

Inspired by microorganisms in nature, a new type of waste-energy-driven catalytic film was explored for the first time using magnetically actuated artificial cilia. Due to its singular characteristic ciliary movement, the inner-motile catalytic film is capable of capturing waste mechanical energy from flows, which can unexpectedly drive electrochemical reactions in solutions. Based on this, the piezoelectric deposition of Ag nanoparticles was achieved for the first time, which makes Ag nanoparticles distribute more evenly on the body of ZnO nanowires, enhancing the catalytic performance dramatically. Moreover, the influence of Ag nanoparticles on the piezoelectric catalysis was also detected, which can boost the deeper understanding of the piezo-catalytic mechanism. In summary, the inner-motile strategy facilitates the realization of waste-energy-driven catalytic technology, providing a new working prototype for driving the piezo-chemical reaction.

Therefore, we aimed to examine the association between depressive symptoms and PA among college students with different gender and gender role (masculinity traits and femininity traits) during the COVID-19 pandemic.Participants and Methods: Cross-sectional study included 628 healthy college students from nineteen different locations. The Center for Epidemiological Studies Depression Scales (CES-D), the International Physical Activity Questionnaire - Short Form (IPAQ-SF), and the 50-item Chinese Sex-Role Inventory (CSRI-50) were used to measure depressive symptoms, PA continuous (weekly metabolic equivalent minutes, MET-minutes/week) and categorical indicators (activity level category) and gender role, respectively. The statistical analyses were used in partial correlation analysis, t-test, one-way ANOVA, moderation model tests, and linear regression model tests.Results: Total of 34.72% participants had clinically relevant depression (16, CES-D scale). Total of 58.6% participants were classified as a “low” activity level for spending less time on PA. Depression significantly negatively correlated with MET-minutes/week in moderate-intensity PA but not vigorous and walking scores. Of note, the depression-PA association was only moderated by the “low” activity level group in terms of categorical scores across gender groups. Participants with higher masculinity traits were less likely to have depression among all participants. Moreover, more recovered cases and fewer deaths could also predict the lower depression risk in the “high” activity level group.Conclusion: Moderate-intensity PA is beneficial for reducing depression risk among college students at a low activity level. College students with fewer masculinity traits (regardless of gender) are highly vulnerable to depression during the outbreak of COVID-19. Effective control of the COVID-19 pandemic seems critical to alleviating the burden of mental disorders of the public including depression.Keywords: depression, physical activity, gender, masculinity, femininity, COVID-19

Although endurance running (ER) seems to be a simple repetitive exercise, good ER performance also requires and relies on multiple cognitive and motor control processes. Most of previous neuroimaging studies on ER were conducted using a single MRI modality, yet no multimodal study to our knowledge has been performed in this regard. In this study, we used multimodal MRI data to investigate the brain structural and functional differences between endurance runners (n = 22; age = 26.27 ± 6.07 years; endurance training = 6.23 ± 2.41 years) and healthy controls (HCs; n = 20; age = 24.60 ± 4.14 years). Compared with the HCs, the endurance runners showed greater gray matter volume (GMV) and cortical surface area in the left precentral gyrus, which at the same time had higher functional connectivity (FC) with the right postcentral and precentral gyrus. Subcortically, the endurance runners showed greater GMV in the left hippocampus and regional inflation in the right hippocampus. Using the bilateral hippocampi as seeds, further seed-based FC analyses showed higher hippocampal FC with the supplementary motor area, middle cingulate cortex, and left posterior lobe of the cerebellum. Moreover, compared with the HCs, the endurance runners also showed higher fractional anisotropy in several white matter regions, involving the corpus callosum, left internal capsule, left corona radiata, left external capsule, left posterior lobe of cerebellum and bilateral precuneus. Taken together, our findings provide several lines of evidence for the brain structural and functional differences between endurance runners and HCs. The current data suggest that these brain characteristics may have arisen as a result of regular ER training; however, whether they represent the neural correlates underlying the good ER performances of the endurance runners requires further investigations.

Objective: Sustained attention is critical for various activities of daily living, including engaging in health-enhancing behaviors and inhibition of health compromising behaviors. Sustained attention activates neural networks involved in episodic memory function, a critical cognition for healthy living. Acute exercise has been shown to activate these same neural networks. Thus, it is plausible that engaging in a sustained attention task and engaging in a bout of acute exercise may have an additive effect in enhancing memory function, which was the purpose of this experiment. Methods: 23 young adults (Mage = 20.7 years) completed 2 visits, with each visit occurring approximately 24 hours apart, in a counterbalanced order, including: (1) acute exercise with sustained attention, and (2) sustained attention only. Memory was assessed using a word-list paradigm and included a short- and long-term memory assessment. Sustained attention was induced via a sustained attention to response task (SART). Acute exercise involved a 15-minute bout of moderate-intensity exercise. Results: Short-term memory performance was significantly greater than long-term memory, Mdiff = 1.86, p < .001, and short-term memory for Exercise with Sustained Attention was significantly greater than short-term memory for Sustained Attention Only, Mdiff = 1.50, p = .01. Conclusion: Engaging in an acute bout of exercise before a sustained attention task additively influenced short-term memory function.

Highlights • Exposure to hypoxia impaired attentional ability, executive function, and memory function but not information processing. • The effects of hypoxia on cognition were significantly moderated by sex and cognitive task type but not by other variables. • Performing exercise under a hypoxia setting has significant effects on cognitive improvement, which was moderated by cognitive task type, exercise type, exercise intensity, training type, and hypoxia level., Objective This study aimed to examine (1) the independent effects of hypoxia on cognitive function and (2) the effects of exercise on cognition while under hypoxia. Methods Design: Systematic review with meta-analysis. Data sources: PubMed, Scopus, Web of Science, PsychInfo, and SPORTDiscus were searched. Eligibility criteria for selecting studies: randomized controlled trials and nonrandomized controlled studies that investigated the effects of chronic or acute exercise on cognition under hypoxia were considered (Aim 2), as were studies investigating the effects of hypoxia on cognition (Aim 1). Results In total, 18 studies met our inclusionary criteria for the systematic review, and 12 studies were meta-analyzed. Exposure to hypoxia impaired attentional ability (standardized mean difference (SMD) = –0.4), executive function (SMD = –0.18), and memory function (SMD = –0.26), but not information processing (SMD = 0.27). Aggregated results indicated that performing exercise under a hypoxia setting had a significant effect on cognitive improvement (SMD = 0.3, 95% confidence interval: 0.14 – 0.45, I2 = 54%, p < 0.001). Various characteristics (e.g., age, cognitive task type, exercise type, exercise intensity, training type, and hypoxia level) moderated the effects of hypoxia and exercise on cognitive function. Conclusion Exercise during exposure to hypoxia improves cognitive function. This association appears to be moderated by individual and exercise/hypoxia-related characteristics., Graphical Abstract Image, graphical abstract

People with different levels of music experience have been reported to differ significantly in cognitive abilities such as verbal memory, phonological awareness and reading development. However, studies often comparing the cognitive ability between musicians and non-musicians. Among the non-musicians, there are differences in music experience levels. Besides, many non-musicians with higher music experience than musicians. However, at present there is no reliable and valid measure of music experience in the literature. In the current study we developed the Music Background Experience Questionnaire for use in the field of music psychology. An initial set of 45 items was compiled based on the literature and on semi-structured interviews with 10 musicians and psychologists. These items were then tested in a pilot study of 402 participants. Based on exploratory and confirmatory factor analysis, 11 items were selected and classified into the two dimensions of "music training" and "music contact." A sample of 2,228 participants (1,465 women, average age 27.62 years) then completed the new measure. A subsample of 49 completed the questionnaire again after three weeks. The internal consistency, test-retest reliability, structural validity and construct validity were strong. These strong psychometric properties suggest that the Music Background Experience Questionnaire is appropriate for use in music psychology research.

Background This meta-analytic review aimed to systematically evaluate associations of depression with multiple gender role dimensions (masculinity, femininity, androgyny, and undifferentiated traits) and to determine potential moderators (participant characteristics, study instruments and sociocultural factors) of the relationship. Methods Of 4481 initially identified records in three electronic databases, 58 studies published 1978 to 2021 were included for meta-analysis. Results (1) Association of depression and gender role is moderated by study year and human development indices. (2) Masculinity is a protective factor for depression, while this dominance has declined as life expectancy increases. (3) A negative, weak but significant association between depression and femininity is observed in women, and college students, which starts to emerge with the gradual increase in the national education and income index from 1990 to 2019. (4) Androgynous individuals reported the lowest level of depression as compared with other gender role orientations (masculine, feminine, and undifferentiated trait group). This disparity is becoming more extreme with life expectancy and per capita income index increases. Limitations English-language studies were only included in this review. Conclusions Androgyny might be the most ideal gender role protecting both women and men from depression.

La qualité des soins délivrés aux patients est au cœur des missions de soins dans les centres de lutte contre le cancer (CLCC). Parmi les actions engagées pour son amélioration, le respect de la dignité et de l’autonomie des patients est une priorité. Partant de cette volonté, l’institut Paoli-Calmettes de Marseille et le centre Léon-Bérard de Lyon ont conjointement mené une initiative de nouvelle organisation dans laquelle les patients arrivent debout au bloc opératoire. L’objectif étant « d’assurer un confort optimal de bien-être et une valorisation des capacités physiques ». Cette initiative a été généralisée et, en 2018, 15 des 18 CLCC avaient mis en place cette organisation, de façon plus ou moins avancée, d’autres centres étant en cours de planification. Nous rapportons cette expérience et réunissons les données d’évaluation disponibles qui nous encouragent à poursuivre et étendre cette démarche.

Objectives: To investigate the prevalence and risk factors for poor mental health of Chinese university students during the Corona Virus Disease 2019 (COVID-19) pandemic. Method: Chinese nation-wide on-line cross-sectional survey on university students, collected between February 12th and 17th, 2020. Primary outcome was prevalence of clinically-relevant posttraumatic stress disorder symptoms. Secondary outcomes on poor mental health included prevalence of clinically-relevant anxiety and depressive symptoms, while posttraumatic growth was considered as indicator of effective coping reaction. Results: Of 2,500 invited Chinese university students, 2,038 completed the survey. Prevalence of clinically-relevant PTSD, anxiety, and depressive symptoms, and post traumatic growth (PTG) was 30.8, 15.5, 23.3, and 66.9% respectively. Older age, knowing people who had been isolated, more ACEs, higher level of anxious attachment, and lower level of resilience all predicted primary outcome (all p < 0.01). Conclusions: A significant proportion of young adults exhibit clinically relevant posttraumatic stress disorder (PTSD), anxious or depressive symptoms, but a larger portion of individuals showed to effectively cope with COVID-19 pandemic. Interventions promoting resilience should be provided, even remotely, to those subjects with specific risk factors to develop poor mental health during COVID-19 or other pandemics with social isolation. © Copyright © 2020 Chi, Becker, Yu, Willeit, Jiao, Huang, Hossain, Grabovac, Yeung, Lin, Veronese, Wang, Zhou, Doig, Liu, Carvalho, Yang, Xiao, Zou, Fusar-Poli and Solmi.

Background: This cross-sectional study aimed to investigate whether a long-term engagement in different types of physical exercise may influence resting-state brain networks differentially. In particular, we studied if there were differences in resting-state functional connectivity measures when comparing older women who are long-term practitioners of tai chi chuan or walking. Method: We recruited 20 older women who regularly practiced tai chi chuan (TCC group), and 22 older women who walked regularly (walking group). Both the TCC group and the walking group underwent a resting-state functional magnetic resonance imaging (rs-fMRI) scan. The acquired rs-fMRI data of all participants were analyzed using independent component analysis. Age and years of education were added as co-variables. Results: There were significant differences in default network, sensory-motor network, and visual network of rs-fMRI between the TCC group and walking group (p &lt, 0.05). Conclusions: The findings of the current study suggested that long-term practice of different types of physical exercises (TCC vs. walking) influenced brain functional networks and brain functional plasticity of elderly women differentially. Our findings encourage further research to investigate whether those differences in resting-state functional connectivity as a function of the type of physical exercise have implications for the prevention of neurological diseases.

Background: Cognitive decline is age relevant and it can start as early as middle age. The decline becomes more obvious among older adults, which is highly associated with increased risk of developing dementia (e.g., Alzheimer&rsquo, s disease). White matter damage was found to be related to cognitive decline through aging. The purpose of the current study was to compare the effects of Tai Chi (TC) versus walking on the brain white matter network among Chinese elderly women. Methods: A cross-sectional study was conducted where 42 healthy elderly women were included. Tai Chi practitioners (20 females, average age: 62.9 &plusmn, 2.38 years, education level 9.05 &plusmn, 1.8 years) and the matched walking participants (22 females, average age: 63.27 &plusmn, 3.58 years, educational level: 8.86 &plusmn, 2.74 years) underwent resting-state functional magnetic resonance imaging (rsfMRI) scans. Diffusion tensor imaging (DTI) and graph theory were employed to study the data, construct the white matter matrix, and compare the brain network attributes between the two groups. Results: Results from graph-based analyses showed that the small-world attributes were higher for the TC group than for the walking group (p &lt, 0.05, Cohen&rsquo, s d = 1.534). Some effects were significant (p &lt, 0.001) with very large effect sizes. Meanwhile, the aggregation coefficient and local efficiency attributes were also higher for the TC group than for the walking group (p &gt, 0.05). However, no significant difference was found between the two groups in node attributes and edge analysis. Conclusion: Regular TC training is more conducive to optimize the brain functioning and networking of the elderly. The results of the current study help to identify the mechanisms underlying the cognitive protective effects of TC.

Many studies have indicated that executing a secondary task during encoding has little influence on implicit memory (priming effect). However, relatively few studies have discussed the effect of interference on implicit memory during retrieval. Our previous studies found asymmetry between implicit encoding and retrieval processes, with the priming effect disrupted by retrieval interference. Therefore, the present study investigated why and how the priming effect is affected by interference at retrieval. We adopted a dual-task paradigm, with a lexical decision task as the memory task and an odd-even decision task as the interference task. The effect of interference during retrieval was assessed by comparing the performance in the interference condition with that in the full-attention condition. In Experiment 1, we observed that the priming effect was absent in the synchronous retrieval interference condition. In Experiment 2, asynchronous interference was also found to block the priming effect. To verify the assumption that the priming effect is sensitive to attentional resource competition during retrieval, we used two different manipulations (an extended stimulus interval in the dual-task paradigm, Experiment 3, and an interference inhibition manipulation, Experiment 4) known to reduce attentional distraction. In these experiments, the priming effect was protected from interference effects. We suggest that implicit memory retrieval could be regarded as a conditional automatic process that depends on a configuration of the cognitive system by attention and task sets. If the limited resources are occupied by another task, the implicit retrieval process can be impacted.

To design a new modified sick clothes for electrocardiogram (ECG) monitoring, and to observe its clinical application effect.In order to overcome the shortcomings of the existing modified ECG monitoring clothes, a new type of modified sick clothes was designed on the basis of the traditional sick clothes, and a national utility model patent was obtained. 408 conscious patients with ECG monitoring admitted to department of neurology of the First Affiliated Hospital of Fujian Medical University from January 2015 to June 2018 were enrolled, and they were randomly divided into three groups according to the order of admission for comparing the wearing effect of three kinds of sick clothes. 133 patients dressed traditional clothes, while 139 patients dressed modified ECG monitoring clothes. According to the method reported in the literature, the pockets were removed on the basis of the traditional patient clothes, and a circular hole 5 cm in diameter was made at the position of the electrodes for ECG monitoring, which was used to pass through the lead wire and the electrodes. 136 patients dressed the new modified sick clothes. In view of the inconvenience of ECG monitoring and stimulation of patients' thoracic and abdominal skin by traditional sick clothes, the existing modified ECG monitoring clothes were not easy to operate, the location of electrodes sticking was not easy to judge and the lead line was messy, the new modified sick clothes were still based on the traditional ones. The three circular holes of the existing modified ECG monitoring clothes were made into incisions about 12 cm in length to facilitate the ECG monitoring lead line and electrodes sticking. A compression band or a simple patch was added to each side near the shoulder for tidying up the fixed lead. The self-evaluation of patient's comfort, the operation time of ECG monitoring by nurses, skin allergy rate and lead damage rate were recorded and compared among the three groups.Compared with the traditional sick clothes and the modified ECG monitoring clothes groups, the patients in the new modified sick clothes group had higher comfort [the proportion of no discomfort: 11.0% (15/136) vs. 0% (0/133), 5.8% (8/139); the proportion of severe discomfort: 0% (0/136) vs. 4.5% (6/133), 0.7% (1/139), all P0.05], the installation and disassembly time of ECG monitoring by nurses was significantly shortened [installation time (s): 69.12±16.47 vs. 96.74±3.89, 88.24±9.83; disassembly time (s): 50.24±4.54 vs. 75.76±4.98, 66.54±7.86, all P0.01], and the skin allergies rate [3.7% (5/136) vs. 15.8% (21/133), 8.6% (12/139)] and the insulation loss rate of the lead wires [2.9% (4/136) vs. 15.8% (21/133), 7.9% (11/139)] were significantly lowered (all P0.05).The ECG monitoring patients using new modified sick clothes could increase their comfort, reduce the workload of nurses, save medical consumables, and have beautiful appearance and high practicability, which was worthy of clinical application.

In the study of emotional memory bias in depressed individuals, most previous studies have used emotional materials, but there were significant differences in the effects of different emotion-inducing methods on face memory. In the present study, two experiments were conducted to explore the effects of different emotion-inducing methods on memory between healthy participants and non-clinically depressed participants. The results from experiment 1 showed that when feedback was used as induction, the memory performance of the non-clinical depression group was significantly higher than that of the healthy group under the condition of negative feedback. Under positive and neutral feedback, there were no significant differences between the two groups. In experiment 2, when emotional materials were used as a mode of induction, no significantly difference in each emotional condition between the healthy and depressed groups was found. The results of the present study show that different methods of emotional induction have different effects on depressed participants. Compared with the emotion induced by the emotional material, the non-clinical depressed participants had a better memory effect induced by negative emotional events.

We extended self-consistent field theory to study the phase behavior of supramolecular blends of diblock copolymers with hydrogen-bonding interactions. The hydrogen-bonding interactions are described by Yukawa potentials. The hydrogen-bonding donors and acceptors were modeled as two blocks smeared with opposite screened charges. Hierarchical microstructures such as parallel and perpendicular lamellae-in-lamellae were observed. The appearance of parallel/perpendicular lamellae-in-lamellae depends on the strength of hydrogen-bonding interactions related to the density of hydrogen bonds and the characteristic lengths of the Yukawa potentials. Phase diagrams were correspondingly mapped out, and the domain size, interfacial width and free energies were examined to gain insight into the phase transitions. It was also found that the revealed mechanism can account for some experimental phenomena that are not well explained yet. The present method can be readily further extended to more complicated supramolecular systems with hydrogen-bonding interactions.

Hierarchical lamellae self-assembled from linear multiblock copolymers in thin films are investigated by self-consistent field theory. The thin films are confined between two parallel substrates. The confinement strategy allows generating hierarchical microstructures with various numbers and different orientations of small-length-scale lamellae. Effects of film thickness and surface affinity on the structures are studied. It is found that not only the period of the large- and small-length-scale lamellae but also the orientation of small-length-scale lamellae relative to large-length-scale lamellae can be tuned by varying the film thickness. Moreover, the structures of the hierarchical lamellae can be tailored by changing the surface affinity. Through analyzing free energies of various lamellae, phase diagrams are mapped out. The present work could provide guidance for fabricating hierarchical microstructures in a controllable way.
