ObjectiveTo investigate the instant impact of hemodialysis on the cerebral morphological measurements of patients with end-stage renal disease.Materials and methodsTwenty-five patients undergoing maintenance HD and twenty-eight age-, sex-, and education-matched healthy control were included. The HD group and HC group had 3D high-resolution structural magnetic resonance imaging scans twice and once, respectively. Both groups underwent neuropsychologic tests. The morphological measurements of structural MRI were measured using CAT12 and these measures were compared among three groups. The relationship between morphological measures and (...) clinical parameters and neuropsychological tests were investigated through multiple regression analysis.ResultsCompared to the HC group, the cortical thickness before HD significantly decreased in the bilateral temporal lobe and significantly decreased in the left superior temporal gyrus after HD. The cortical thickness significantly increased in the bilateral temporal lobe, frontal lobe and occipital lobe after HD compared to before HD. The sulcus depth in the bilateral insula, frontal lobe, and parietal lobe after HD significantly increased compared to before HD. No significant differences in sulcus depth between HD and HC were detected. After HD, the cortical thickness of the right parsopercularis was positively correlated with the number connection test-A. Cortical thickness in multiple regions were positively correlated with blood flow velocity and cortical thickness in the left parahippocampal gyrus was negatively correlated with ultrafiltration volume. Patients showed better performance in the digit symbol test and line tracing test after HD compared to before HD, but there were no significant differences in the comparison of neuropsychologic tests between patients and HC.ConclusionThe instant morphological changes were captured during a single hemodialysis in HD patients. There was an association between these instant changes in the brain and clinical parameters and neuropsychologic tests. This work implied the instant impact of a single hemodialysis impact on the brain in HD patients. (shrink)

This paper addresses the simultaneous attitude and position tracking of a target spacecraft in the presence of general unknown bounded disturbances in the framework of dual quaternions, which provides a concise and integrated description of the coupled rotational and translational motions. By virtue of the newly introduced dual direction cosine matrix, the dimension of the dual quaternion-based relative motion dynamics written in vector/matrix form can be lowered to six. Treating the disturbances as unknown parameters, a modular adaptive pose tracking control (...) scheme composed of two separately designed parts is then derived. One part is the adaptive disturbance estimator designed based on the immersion and invariance theory. Driven by the disturbance estimation errors, it can realize exponential convergence of the estimations and has the nice “parameter lock” property, which can hardly be expected in the conventional certainty equivalent adaptive controllers. The other part is a proportional-derivative-like pose tracking controller where the estimated disturbances are directly used. The closed-loop stability of the relative motion system under different kinds of disturbances is proven by Lyapunov stability analysis. Simulations and comparisons with two previous dual quaternion-based controllers demonstrate the novel features and performance improvements of the proposed control scheme. (shrink)

During the COVID-19 pandemic, business managers are facing many challenges from a severe challenge. Many organizations have changed their original management mode and organizational behavior to improve employees’ organizational citizenship behavior, thus reducing their sense of anxiety and incapability. Thereinto, job performance of the employees also affects the growth and development of the organization. To explore how to fragment employees’ positive psychology and job performance, this study discusses the influence on employees’ subjective wellbeing and job performance from relevant factors at (...) the organizational and individual levels. Also, to explore the influence of organizational support and occupation self-efficacy on job performance and the mediating role of subjective wellbeing during COVID-19, a total of 618 valid questionnaires were collected from all walks of life in 2020. Hypotheses were tested by structural equation modeling and Bootstrap technology. The results show that: Professional self-efficacy and subjective wellbeing have a significant positive impact on job performance; Subjective wellbeing plays a complete mediating role between organizational support and job performance, and subjective wellbeing plays a partial mediating role between professional self-efficacy and job performance; Compared with the sense of organizational support, the positive effect of self-efficacy on job performance is more significant.

Accurate and rapid defect identification based on pulsed eddy current testing plays an important role in the structural integrity and health monitoring of in-service equipment in the renewable energy system. However, in conventional data-driven defect identification methods, the signal feature extraction is time consuming and requires expert experience. To avoid the difficulty of manual feature extraction and overcome the shortcomings of the classic deep convolutional network, such as large memory and high computational cost, an intelligent defect recognition pipeline based on (...) the general Warblet transform method and optimized two-dimensional DCNN is proposed. The GWT method is used to convert the one-dimensional PECT signal to a 2D grayscale image used as the input of 2D DCNN. A compound method is proposed to optimize the baseline VGG16, a well-known DCNN, from four aspects including reducing the input size, adding batch normalization layer after every convolutional layer and fully connection layer, simplifying the FCs, and removing unimportant filters in Convs so as to reduce memory and computational costs while improving accuracy. Through a pulsed eddy current testing experiment considering interference factors including liftoff and noise, the following conclusion can be obtained. The time-frequency representation obtained by the GWT method not only has excellent ability in terms of the transient component analysis but also is less affected by the reduction of image size; the proposed optimized DCNN can accurately identify defect types without manual feature extraction. And compared to the baseline VGG16, the accuracy obtained by the optimized DCNN is improved by 7%, to about 99.58%, and the memory and computational cost are reduced by 98%. Moreover, compared with other well-known DCNNs, such as GoogLeNet, Inception V3, ResNet50, and AlexNet, the optimized network has significant advantages in terms of accuracy and computational cost, too.

Recent challenges to Chomsky's poverty of the stimulus thesis for language acquisition suggest that children's primary data may carry “indirect evidence” about linguistic constructions despite containing no instances of them. Indirect evidence is claimed to suffice for grammar acquisition, without need for innate knowledge. This article reports experiments based on those of Reali and Christiansen (2005), who demonstrated that a simple bigram language model can induce the correct form of auxiliary inversion in certain complex questions. This article investigates the nature (...) of the indirect evidence that supports this learning, and assesses how reliably it is available. Results confirm the original finding for one specific sentence type but show that the model's success is highly circumscribed. It performs poorly on inversion in related constructions in English and Dutch. Because other, more powerful statistical models have so far been shown to succeed only on the same limited subset of cases as the bigram model, it remains to be seen whether stimulus richness can be substantiated more generally.

This paper presents an integrated approach to plan smooth path for robots docking in unknown environments with obstacles. To determine the smooth collision-free path in obstacle environment, a tree structure with heuristic expanding strategy is designed as the foundation of path planning in this approach. The tree employs 3D Dubins curves as its branches and foundation for path feasibility evaluation. For the efficiency of the tree expanding in obstacle environment, intermediate nodes and collision-free branches are determined inspired by the elastic (...) band theory. A feasible path is chosen as the shortest series of branches that connects to the docking station after the sufficient expansion of the tree. Simulation results are presented to show the validity and feasibility of the proposed approach. (shrink)

This paper explores the often-overlooked role of teaching assistants (TAs) in engineering ethics courses, and a particular challenge that TAs face in these roles. TAs not only undertake tasks like instructors, which include teaching, guiding, and evaluating courses, but they also assume the roles of “intermediaries between instructors and students” and “learners becoming teachers.” These distinct roles present TAs with unique challenges, one of which we call the neutrality problem. This problem pertains to whether TAs can and should maintain a (...) neutral stance in the classroom, particularly when students articulate ideas that deviate from the values promoted in the course or held by the TAs. Using a real-life teaching experience as illustrative, we claim that it is challenging and, at times, undesirable for TAs to achieve pedagogical neutrality, primarily due to their pre-existing understanding of ethics and the actual situation of the students. Nevertheless, we posit that TAs should strive to foster an environment where students are encouraged to improve their ethical awareness. Through the underrepresented lens of TAs, we aim to initiate a multi-faceted dialogue on the teaching philosophy and goal of engineering ethics. (shrink)

Language teacher research is conducive to the development of teachers’ teaching skills and professional careers. Thus, many English teacher education programs require student teachers to do research. However, some empirical findings suggest that English as a foreign language student teachers lack research motivation. Consequently, finding suitable interventions to increase their research motivation has become increasingly necessary. In light of the importance of research motivation intervention, this study involved designing an experiment to identify the effect of a value and interest intervention (...) including the sharing of positive research experiences to improve student teachers’ research motivation. Quantitative questionnaires and qualitative semi-structured interviews were used to gather evidence on the change in student teachers’ research motivation during the intervention. The interview data revealed that student teachers’ research motivation was influenced by their belief in the value of research to their teaching practice. The experiment results suggested that student teachers’ intrinsic and extrinsic research motivations both increased after the intervention. However, the intervention was not effective in curbing their failure avoidance tendency. Pedagogical implications of the results are discussed at the end of this article. (shrink)

Theoretical studies suggest that, when determining the workplace safety level, CEOs face a trade-off between ex ante safety-improving expenditures and the expected losses due to ex post injury and illness occurrences. We examine whether firms with higher CEO inside debt holdings have safer workplaces. Using establishment-level employee workplace injury and illness data, we find that CEOs’ inside debt holdings are negatively associated with employee workplace injury and illness cases. This relationship is more pronounced if workers’ compensation premiums are more sensitive (...) to injury claims and for firms with more government business and less pronounced for firms with higher levels of secured debt. We provide some evidence that our main result stems from CEOs increasing safety investments. Our empirical results are shown to be robust under a batch of robustness tests and when considering potential endogeneity problems. Our findings suggest that CEOs with higher levels of inside debt holdings are more sensitive to wealth loss due to employee injury and illness, leading to a safer workplace. (shrink)

International integration is deepening, so people develop in all aspects. In society, communities with individuals have relationships in humans' material and spiritual life. When society grows, more people's knowledge of the world needs to learn so that people can understand themselves and act for the development of society. The article studies the thought of Thomas Aquinas to clarify human nature in social life. The paper uses analytical, synthesis, and argumentative methods to explain human nature with its behaviors and perceptions in (...) social life; Aquinas argued that it is human nature to do the right thing to achieve happiness. However, society is more progressive and liberals, but people always realize their lives have many injustices and difficulties. People want their lives to be happy and good but feel depressed. In this article, in an excellent society, people live according to the law and adjust their behavior according to the regulations of society; each person in the society is also better, from which the society is also humane and reasonable that the basis for building a better society in Vietnam.

La couverture indique :"L'infini est le sujet le plus vaste que l'imagination puisse embrasser. Il a tout le temps fasciné les hommes, qu'ils soient artistes, philosophes ou scientifiques. Mais l'infini se manifeste-t-il vraiment dans la réalité physique, ou est-il seulement un concept de notre imagination, comme le pensait Aristote? Des artistes comme Escher, des écrivains comme Borges ont tenté de le représenter, mais c'est Georg Cantor qui assoit fermement l'infini dans le paysage des mathématiques et nous dévoile ses propriétés étranges (...) et magiques. L'univers est, par excellence, le lieu où l'infini se manifeste. Dans un univers infini, nous serions confrontés au paradoxe de l'éternel retour, où chacun de nous posséderait un nombre infini de sosies. Les avancées en physique de ces dernières décennies ont donné au mot "infini" un sens nouveau. Il se réfère non seulement à notre univers, mais aussi à une infinité d'univers parallèles, le tout formant un vaste et fantastique "multivers". A ces sujets vertigineux, Trinh Xuan Thuan apporte ses réflexions avec la pédagogie lumineuse, à la fois scientifique, philosophique et poétique qui lui est coutumière et qui fait le grand succès de La Mélodie secrète, du Chaos et l'harmonie, et, plus récemment, du Cosmos et le lotus.".

The relationships between age and the life-supporting treatments use, and between gender and the life-supporting treatments use are still controversial. Using extracorporeal membrane oxygenation as an example of life-supporting treatments, the objectives of this study were: to examine the relationship between age and the extracorporeal membrane oxygenation use; to examine the relationship between age and the extracorporeal membrane oxygenation use; and to deliberate the ethical and societal implications of age and gender disparities in the initiation of extracorporeal membrane oxygenation. This (...) is a population-based, retrospective cohort study. Taiwan’s extracorporeal membrane oxygenation cases from 2000 to 2010 were collected. The annual incidence rate of extracorporeal membrane oxygenation use adjusting for both age and gender distribution for each year from 2000 to 2010 was derived using the population of 2000 as the reference population. The trend of extracorporeal membrane oxygenation use was examined using time-series linear regression analysis. We conducted joinpoint regression for estimating the trend change of extracorporeal membrane oxygenation use. The trends of extracorporeal membrane oxygenation use both for different gender groups, and for different age groups have been significantly increasing over time. Men were more likely to be supported by extracorporeal membrane oxygenation than women. Women’s perspectives toward life and death, and women’s perception of well-being may be associated with the phenomenon. In addition, the patients at the age of 65 or older were more likely to be supported by extracorporeal membrane oxygenation than those younger than 65. Family autonomy/family-determination, and the Confucian tradition of filial piety and respecting elders may account for this phenomenon. This study showed gender and age disparities in the initiation of extracorporeal membrane oxygenation use in Taiwan, which may be accounted for by the cultural and societal values in Taiwan. For a healthcare professional who deals with patients’/family members’ medical decision-making to initiate life-supporting treatments, he/she should be sensitive not only to the legality, but also the societal and ethical issues involved.

The authors find East Asians to be holistic, attending to the entire field and assigning causality to it, making relatively little use of categories and formal logic, and relying on "dialectical" reasoning, whereas Westerners, are more analytic, paying attention primarily to the object and the categories to which it belongs and using rules, including formal logic, to understand its behavior. The 2 types of cognitive processes are embedded in different naive metaphysical systems and tacit epistemologies. The authors speculate that the (...) origin of these differences is traceable to markedly different social systems. The theory and the evidence presented call into question long-held assumptions about basic cognitive processes and even about the appropriateness of the process–content distinction. (shrink)

Abstract:The most important themes of Wang Lü's painting theory are the "true self" and the "true thing." One reason this topic has not received sufficient attention is that the original text was altered. This article aims to correct and reinterpret the text. After textual research and interpretation, Wang Lü's paintings and painting theory have been reevaluated. This article also responds to some difficult topics such as the relationship between "form" (ᔶ) and "meaning" (ᛣ) and between "following" (ᕲ) and "not following" (...)

It has been found in many cases that consumers are prone to exhibit impulsive buying behavior that is manifested as being immediate, emotional, and irresponsible especially under short video scenario. Supported by the customer inspiration theory, this study explores the psychological mechanism underlying impulse purchase in short videos that differentiates the traditional web shopping by the strong sense of presence in short video marketing. On the basis of a questionnaire survey and three laboratory experiments, this study examines the relationship among (...) presence, customer inspiration, and impulse purchase intention. The empirical results point to the fact that social presence, co-presence, and physical presence have significant positive effects on impulse purchase intention, and customer inspiration mediates the effect of social presence, physical presence, and co-presence on impulse purchase intention. Furthermore, it is indicated that social and co-presence have stronger influences on impulse purchase intention than physical presence, thus proving a stronger effect of social factors on impulse purchase intention than physical factors in short video environment. The research results testify the impact of presence on consumer behavior in the upgrading short video marketing and provide valuable reference for marketing strategies to shorten consumers' decision-making time in short video purchase.

A total of 944 expressed sequence tags generated 2212 EST loci mapped to homoeologous group 1 chromosomes in hexaploid wheat. EST deletion maps and the consensus map of group 1 chromosomes were constructed to show EST distribution. EST loci were unevenly distributed among chromosomes 1A, 1B, and ID with 660, 826, and 726, respectively. The number of EST loci was greater on the long arms than on the short arms for all three chromosomes. The distribution of ESTs along chromosome arms (...) was nonrandom with EST clusters occurring in the distal regions of short arms and middle regions of long arms. Duplications of group 1 ESTs in other homoeologous groups occurred at a rate of 35.5%. Seventy-five percent of wheat chromosome 1 ESTs had significant matches with rice sequences, where large regions of conservation occurred between wheat consensus chromosome 1 and rice chromosome 5 and between the proximal portion of the long arm of wheat consensus chromosome 1 and rice chromosome 10. Only 9.5% of group 1 ESTs showed significant matches to Arabidopsis genome sequences. The results presented are useful for gene mapping and evolutionary and comparative genomics of grasses. (shrink)
