Aiming at the problem of low pedestrian target detection accuracy, we propose a detection algorithm based on optimized Mask R-CNN which uses the latest research results of deep learning to improve the accuracy and speed of detection results. Due to the influence of illumination, posture, background, and other factors on the human target in the natural scene image, the complexity of target information is high. SKNet is used to replace the part of the convolution module in the depth residual network (...) model in order to extract features better so that the model can adaptively select the best convolution kernel during training. In addition, according to the statistical law, the length-width ratio of the anchor box is modified to make it more accord with the natural characteristics of the pedestrian target. Finally, a pedestrian target dataset is established by selecting suitable pedestrian images in the COCO dataset and expanded by adding noise and median filtering. The optimized algorithm is compared with the original algorithm and several other mainstream target detection algorithms on the dataset; the experimental results show that the detection accuracy and detection speed of the optimized algorithm are improved, and its detection accuracy is better than other mainstream target detection algorithms.

A fuzzy predictive fault-tolerant control scheme is proposed for a wide class of discrete-time nonlinear systems with uncertainties, interval time-varying delays, and partial actuator failures as well as unknown disturbances, in which the main opinions focus on the relevant theory of FPFTC based on Takagi-Sugeno fuzzy model description of these systems. The T-S fuzzy model represents the discrete-time nonlinear system in the form of the discrete uncertain time-varying delay state space, which is firstly constructed by a set of local linear (...) models and the nonlinear membership functions. The novel improved state space model can be further obtained by extending the output tracking error to the constructed model. Then the fuzzy predictive fault-tolerant control law based on this extended model is designed, which can increase more control degrees of freedom. Utilizing Lyapunov-Krasovskill theory, less conservative delay-range-dependent stable conditions in terms of linear matrix inequality constraints are given to ensure the asymptotically robust stability of closed-loop system. Meanwhile, the optimized cost function and H-infinity performance index are introduced to the stable conditions to guarantee the robust performance and antidisturbance capability. The simulation results on the temperature control of a strong nonlinear continuous stirred tank reactor show that the proposed control scheme is feasible and effective. (shrink)

The output feedback controller is designed for a class of stochastic nonlinear systems that satisfy uncertain function growth conditions for the first time. The multivariate function growth condition has greatly relaxed the restrictions on the drift and diffusion terms in the original stochastic nonlinear system. Here, we cleverly handle the problem of uncertain functions in the scaling process through the function maxima theory so that the Ito differential system can achieve output stabilization through Lyapunov function design and the solution of (...) stochastic nonlinear system objects satisfies the existence of uniqueness, ensuring that the system is globally asymptotically stable in the sense of probability. Furthermore, it is concluded that the system is inversely optimally stable in the sense of probability. Finally, we apply the theoretical results to the practical subsea intelligent electroexecution robot control system and obtain good results. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:RusselL on Chinese Civilization 23 RUSSELL ON CHINESE CIVILIZATIONI Yu DONG Ph}losophy / McMaster University Hamilton, Ont., Canada L8s 4K1 1 I am indebted to Nicholas Griffin for his valuable comments and encouragement. I thank Marty Fairbairn and Perer Lovrick for many corrections in the paper. I am also greatly indebred to Ken Blackwell for his helpful criticisms and suggesrions. • (London: Allen & Unwin, 1922), p. 20. (...) 3 Karl Popper, The Open Society and Its Enemies (Princeron: Princeton U. P.), p. 173· B ertrand Russell arrived in China with Dora Black in October 1920. World War I had deepened his disillusionment with both the capitalist system and Western civilization in general. Seeking a socialist solution, he had visited Soviet Union just a few months before. But he had found that the Communist state there presented an unappealing alternative to the capitalist West in that it treated its citizens as slaves. The sad mood in which he "set out for China to seek a new hope"2 was described in his The Problem of China, published in 1922 after his nine-month visit: "It was on the Volga, in the. summer of 1920, that I first realized how profound is the disease in our Western mentality, which the Bolsheviks are attempting to force upon an essentially Asiatic population, just as Japan and the West are doing in China" (p. 18). The 1920S were a time when China, both as a nation and as a civilization, was in deep trouble. Her young people were eagerly looking outside their country to find a way of saving her. Since the 1840 Opium War, the Western Powers had poured into China, which had been a closed society, at least in Karl Popper's sense,3 for more than 3,000 years. With the collapse of the Qing dynasty in 19I1, China had been thrown into a state of anarchy by feuding warlords. The Great World Powers had both politically and economically dominated China through successive wars with her;4 through demanding indemnities, the cession of territory, fixed tariffs, etc.; and through controlling the corrupt and inept central government and warlords. Meanwhile, China was plagued by famine, piracy, brigandage, incipient rebellion,5 and the failures of various attempts at reform and revolution.6 China was well on the way toward disintegration, divided into "spheres of influence" by Britain, Germany, France, Russia and, especially, Japan. In the 1920S, China was also in the period of the May Fourth Movement-named after a popular student protest on 4 May 1919against foreign imperialism and an impotent Chinese government. It was agitated by the Treaty of Versailles which transferred, at the request ofJapan, the properties and privileges of the German sphere of influence in the Shandong Peninsula to Japan. This movement advocated learning science and adopting democratic principles in order to save China. It is important in Chinese history as a symbol of Chinese awareness of the need for the most profound changes in her tradition. All of these factors constituted the background to Russell's visit to China and thus affected the formation of his distinct view of the problem of China.? The invitation to him was a part of Chinese efforts in seeking methods from the West to save their country. Russell had already been known in China as a great philosopher, not only for his philosophy of logic and science, but also for his views on social problems. Some Chinese had access to his books: Principles ofSocial Reconstruction (1916), Political Ideals (1917), Roads To Freedom (1918), and magazine publication of parts of The Practice and Theory ofBolshevism (1920).8 Considering this background, it is quite understandable why 4 For example, Brirain and France 1856-60, Japan 1894-95, 1914-15. 5 For example, Taiping 1850-65, and the Boxer Rebellion of 1900. 6 The revolution of 1911 actually just changed the name of the government, rather than the reality of society. 7 A detailed description of this background as "psychological roots" can be seen in S. P. Odgen, "The Sage in the Inkpot", Modern Arian Studies, 16 (1982): 529-600. 8 For example, Zhang Shenfu, a student originally majoring in mathematics in Beijing University, had read almost all of...

The purpose of this study was to develop and test a model capturing the effects of ethics institutionalization on employee experiences in work life and overall life satisfaction. It was hypothesized that explicit ethics institutionalization has a positive effect on implicit ethics institutionalization, which in turn enhances employee experiences in work life. It was also hypothesized that employee work life experiences have a positive effect on overall life satisfaction and happiness, moderated by work–family life conflict. Data were collected though a (...) survey of marketing managers in Italy. The data provide good but partial support for the model. Theoretical and managerial implications are discussed. (shrink)

The creation of QCD is one of greatest achievements in the history of science. It has radically changed our conception of the fundamental ontology of the physical world and its underlying dynamics. What it has discovered are more than new particles and a new force, but rather a deeper level of physical reality, a new kind of entities. Dynamically, the strong nuclear forces are no longer taken to be fundamental, but are relegated to the status of the un-cancelled residue of (...) far stronger long range force mediated by gluon. From a long term perspective, perhaps more important than these discoveries is that it breaks a new path to explore many novel features of an unknown layer of the physical world, such as instanton, the theta vacuum and effective energy. The notion of effective energy allows us to conceptualize the mysterious quantum number flow and hadronization. Although the metaphysical status of effective energy is not quite clear at this moment, but a window is open for conceptualizing the physical world that is in complex processes of transmutations in a unified way.

This study had two aims: to test the effect and the effect size of specific problematic Internet use [online shopping, online pornography, social network site usage, and Internet gaming] on generalized problematic Internet use and to reveal the gender differences in GPIU and SPIU for students from the elementary school level to the university level. In total, 5,215 Chinese students from four types of schools provided self-report data on demographic variables, online shopping, online pornography, SNS usage, Internet gaming, and GPIU. (...) After calculations had been controlled for demographic variables, the results indicated that online shopping, online pornography, SNS usage, and Internet gaming positively predicted GPIU—and Internet gaming was the most critical predictor of GPIU—and that gender differences were revealed in Internet gaming and GPIU in all educational levels, except at senior high school where the gender differences in GPIU were not significant. Significant gender differences were found for online shopping and online pornography for all educational levels above elementary school. These results provided further understanding of the association between GPIU and SPIU and gender differences in PIU, which suggested that gender differences across different educational levels should be considered in interventions of PIU.

There is increasing interest in clarifying how different face emotion expressions are perceived by people from different cultures, of different ages and sex. However, scant availability of well-controlled emotional face stimuli from non-Western populations limit the evaluation of cultural differences in face emotion perception and how this might be modulated by age and sex differences. We present a database of East Asian face expression stimuli, enacted by young and older, male and female, Taiwanese using the Facial Action Coding System (FACS). (...) Combined with a prior database, this present database consists of 90 identities with happy, sad, angry, fearful, disgusted, surprised and neutral expressions amounting to 628 photographs. 20 young and 24 older East Asian raters scored the photographs for intensities of multiple-dimensions of emotions and induced affect. Multivariate analyses characterized the dimensionality of perceived emotions and quantified effects of age and sex. We also applied commercial software to extract computer-based metrics of emotions in photographs. Taiwanese raters perceived happy faces as one category, sad, angry, and disgusted expressions as one category, and fearful and surprised expressions as one category. Younger females were more sensitive to face emotions than younger males. Whereas older males showed reduced face emotion sensitivity, older female sensitivity was similar or accentuated relative to young females. Commercial software dissociated six emotions according to the FACS demonstrating that defining visual features were present. Our findings show that East Asians perceive a different dimensionality of emotions than Western-based definitions in face recognition software, regardless of age and sex. Critically, stimuli with detailed cultural norms are indispensable in interpreting neural and behavioral responses involving human facial expression processing. To this end, we add to the tools, which are available upon request, for conducting such research. (shrink)

Due to the outbreak of the Coronavirus Disease-2019 pandemic and consequent confinement measures, young people are vulnerable to mental health problems. The current study compared a group of 440 young adolescents and a group of 330 emerging adults to investigate the extent to which perceived social support and psychological capital were differentially associated with mental health problems. Participants were asked to report their current psychosocial adaptation status during the COVID-19 pandemic, and data were collected via online questionnaires during a relatively (...) severe period of COVID-19 in China. Results of the multi-group path analysis indicated that the effect of perceived social support on mental health problems was mediated by PsyCap for young adolescents, but not for emerging adults. These results were discussed with respect to the mechanism of how social support and PsyCap serve as protective mental health factors for youth in the context of the COVID-19 pandemic. (shrink)

ObjectiveSchizophrenia is a mental disorder that is characterized by progressive cognitive impairment. Objective measures of cognitive function may provide reliable neurobiomarkers for patients with schizophrenia. The goal of the current work is to explore the correlation between resting theta power and cognitive performance in patients with schizophrenia.MethodsTwenty-two patients with schizophrenia and 23 age-, sex-, and education-matched healthy controls were included in this study. The MATRICS Consensus Cognitive Battery was used for cognitive evaluation and the Positive and Negative Syndrome Scale for (...) evaluation of clinical symptoms. EEGs were acquired in the resting state with closed and opened eyes. Between the two groups, we compared the relative theta power and examined their relationship with cognitive performance.ResultsCompared to healthy controls, patients with schizophrenia showed significantly higher theta power, both with eyes closed and open. When the eyes were open, negative correlations were found in patients with schizophrenia between theta power in the central and parietal regions with processing speed scores, and between the theta power of the Pz electrode and verbal learning and reasoning and problem-solving scores. In the control group, theta power over the Fz electrode was negatively correlated with processing speed.ConclusionsOur findings showed that theta activity increased in certain brain regions during resting state in schizophrenia. Negative associations between resting theta power over the parietal-occipital regions with MCCB domains scores suggest that altered theta activity can be used as a neurobiological indicator to predict cognitive performance.

Background: Truth-telling toward terminally ill patients is a challenging ethical issue in healthcare practice. However, there are no existing ethical guidelines or frameworks provided for Chinese nurses in relation to decision-making on truth-telling of terminal illness and the role of nurses thus is not explicit when encountering this issue. Objectives: The intention of this paper is to provide ethical guidelines or strategies with regards to decision-making on truth-telling of terminal illness for Chinese nurses. Methods: This paper initially present a case (...) scenario and then critically discuss the ethical issue in association with ethical principles and philosophical theories. Instead of focusing on attitudes toward truth disclosure, it aims to provide strategies regarding this issue for nurses. It highlights and discusses some of the relevant ethical assumptions around the perceived role of nurses in healthcare settings by focusing on nursing ethical virtues, nursing codes of ethics, and philosophical perspectives. And Confucian culture is discussed to explicate that deontology does not consider family-oriented care in China. Conclusion: Treating each family individually to explore the family’s beliefs and values on this issue is essential in healthcare practice and nurses should tailor their own approach to individual needs regarding truth-telling in different situations. Moreover, the Chinese Code of Ethics should be modified to be more specific and applicable. Finally, a narrative ethics approach should be applied and teamwork between nurses, physicians and families should be established to support cancer patients and to ensure their autonomy and hope. Ethical considerations: This paper was approved by the Ethics Committee of The Second Affiliated Hospital of Guangzhou Medical University. The authors have obtained consent to use the case study and it has been anonymised to preserve the patient's confidentiality. (shrink)

Motivated by the developments in contemporary mathematical physics and the related interpretive and historiographical works on these developments, a structuralist and historically constitutive and constructive approach to scientific realism (SHASR) is proposed to address the challenges Thomas Kuhn raised against scientific realism, and to remove the defects of the currently available dissatisfactory responses the structuralists put forward to the challenges. The paper shows that SHASR productively exploits the insights from both Kuhn’s historicism and his critics’ structuralism, while avoids the traps (...) in both traditions. Then, after a brief comparison between SHASR and the increasingly popular neo-Kantian post-Kuhnian philosophy of science recommended and defended by Michael Freedman and some others, it concludes with a big picture about the science-world relationship derived from the notion of emergence conceptualized within the framework of SHASR, whose bearings on the Kantian question of the phenomenal - noumenal relationship are worth further explorations.

BackgroundAt present, adherence to antipsychotic treatment is often poor, leading to the recurrence of symptoms. This increases the likelihood of the patient experiencing disability and thus increases the disease burden for the patient, their family, and society as a whole. However, to date, there is no clear evidence regarding the effect of medication adherence interventions on outcomes for patients with schizophrenia. Moreover, the traditional intervention methods are limited by manpower and resources in low- and middle-income countries. Recent studies have demonstrated (...) that increasing a patient’s level of self-compassion may improve their treatment adherence. Online mental health care interventions have advantages in terms of feasibility and acceptability for patients with schizophrenia. In this regard, a WeChat-based self-compassion training protocol to improve patient treatment adherence was designed in this study and will be evaluated in the future to determine its impact on patients with schizophrenia.MethodsThe protocol for the randomized controlled trial is based on the SPIRIT 2013 statement. This parallel RCT will aim to recruit 392 patients with schizophrenia who will be randomized at a 1:1 ratio into a 3-week intervention or control group. Both groups will receive routine care. The intervention group will also receive WeChat-based self-compassion training, which requires participants to complete three tasks every day, including a reading task, a meditation task, and a self-compassion journal task. The control group will receive WeChat-based psychological health education, which will only require participants to read positive articles about psychological health every day. Medication adherence, self-compassion, stigma, and social support will be measured at baseline, immediately after the intervention, and 3 weeks after the intervention. Program feasibility will be evaluated throughout the course of the study, and acceptability will be measured immediately after the intervention.Expected results:The intervention described here will address the barriers to accessing mental health care for people with schizophrenia, including patients’ desire for independent management, difficulty accessing providers, and concerns about privacy and stigma. The current study provides guidance for clinical nurses to carry out psychological intervention, with the ultimate aim of addressing the problems associated with a shortage of psychological professionals in low- and middle-income countries.

Stroke and other neurological disorders have an effect on mobility which has a significant impact on independence and quality of life. The core rehabilitation requirements for patients with lower limb motor dysfunction are gait training, restand, and mobility. In this work, we introduce a newly developed multifunctional wheelchair that we call “ReChair” and evaluated its performance preliminarily. ReChair seamlessly integrates the mobility, gait training, and multiposture transformation. ReChair driving and multiposture transformation are done using the voice, button, and mobile terminal (...) control. This work describes the functional requirements, mechanical structure, and control system and the overall evaluation of ReChair including the kinematic simulation of the multiposture transformation and passive lower limb rehabilitation training to quantitatively verify the motion capability of ReChair, the voice control system evaluation that shows how the voice recognition system is suitable for home environment, the sensorless speed detection test results that indicate how the wheel speeds measured by sensorless method are appropriate for travelling control, and the passive and balance training test results that show how the lower limb rehabilitation training in daily life by ReChair is convenient. Finally, the experimental results show that ReChair meets the patients’ requirements and has practical significance. It is cost-effective, easy to use, and supports multiple control modes to adapt to different rehabilitation phases. (shrink)

Free will is one of the oldest and most debated topics in the history of philosophy. Both positivist philosophy and humanist philosophy considered the problem of free will to be the most difficult issues to untangle. In recent years, psychologists have begun to apply the methods of empirical science to study the psychological mechanism, impact and expression of free will. The general consensus is that free will is an illusion, but people still believe in its existence. Free will has been (...) found closely related to moral responsibility, moral behavior, creativity, self-esteem and subjective well-being. Future research should define free will in more psychological sense, and to explore the generation mechanism and function of free will in everyday life. Theoretical and methodological advances are need to extend our understanding of free will and its psychological impacts to human being. (shrink)

Searching is one of the most fundamental operations in many complex systems. However, the complexity of the search process would increase dramatically in high-dimensional space. K-dimensional tree, as a classical data structure, has been widely used in high-dimensional vital data search. However, at present, common methods proposed for KD tree construction are either unstable or time-consuming. This paper proposed a new algorithm to construct a balanced KD tree based on presorted results. Compared with previous similar method, the new algorithm could (...) reduce the complexity of the construction process from O level to O level, where K is the number of dimensions and N is the number of data. In addition, with the help of presorted results, the performance of the new method is no longer subject to the initial conditions, which expands the application scope of KD tree. (shrink)

ObjectiveThis study aimed to investigate the morphometric alterations in the cortical and subcortical structures in multiple system atrophy patients with mild cognitive impairment, and to explore the association with cognitive deficits.MethodsA total of 45 MSA patients and 29 healthy controls were recruited. FreeSurfer software was used to analyze cortical thickness, and voxel-based morphometry was used to analyze the gray matter volumes. Cortical thickness and gray matter volume changes were correlated with cognitive scores.ResultsCompared to healthy controls, both MSA subgroups exhibited widespread (...) morphology alterations of brain structures in the fronto-temporal regions. Direct comparison of MSA-MCI and MSA-only patients showed volume reduction in the left superior and middle temporal gyrus, while cortical thinning was found in the left middle and inferior temporal gyrus in MSA-MCI patients. Cortical thinning in the left middle temporal gyrus correlated with cognitive assessment and disease duration.ConclusionStructural changes in the brain occur in MSA-MCI patients. The alteration of brain structure in the left temporal regions might be a biomarker of cognitive decline in MSA-MCI patients. (shrink)
