A superheterodyne receiver is a type of device universally used in a variety of electronics and information systems. Fault detection and diagnosis for superheterodyne receivers are therefore of critical importance, especially in noise environments. A general purpose fault detection and diagnosis scheme based on observers and residual error analysis was proposed in this study. In the scheme, two generalized regression neural networks are utilized for fault detection, with one as an observer and the other as an adaptive threshold generator; faults (...) are detected by comparing the residual error and the threshold. Then, time and frequency domain features are extracted from the residual error for diagnosis. A probabilistic neural network acts as a classifier to realize the fault diagnosis. Finally, to mimic electromagnetic environments with noise interference, simulation model under different fault conditions with noise interferences is established to test the effectiveness and robustness of the proposed fault detection and diagnosis scheme. Results of the simulation experiments proved that the presented method is effective and robust in simulated electromagnetic environments. (shrink)

Electromechanical actuators are more and more widely used as actuation devices in flight control system of aircrafts and helicopters. The reliability of EMAs is vital because it will cause serious accidents if the malfunction of EMAs occurs, so it is significant to detect and diagnose the fault of EMAs timely. However, EMAs often run under variable conditions in realistic environment, and the vibration signals of EMAs are nonlinear and nonstationary, which make it difficult to effectively achieve fault diagnosis. This paper (...) proposed a fault diagnosis method of electromechanical actuators based on variational mode decomposition multifractal detrended fluctuation analysis and probabilistic neural network. First, the vibration signals were decomposed by VMD into a number of intrinsic mode functions. Second, the multifractal features hidden in IMFs were extracted by using MFDFA, and the generalized Hurst exponents were selected as the feature vectors. Then, the principal component analysis was introduced to realize dimension reduction of the extracted feature vectors. Finally, the probabilistic neural network was utilized to classify the fault modes. The experimental results show that this method can effectively achieve the fault diagnosis of EMAs even under diffident working conditions. Simultaneously, the diagnosis performance of the proposed method in this paper has an advantage over that of EMD-MFDFA method for feature extraction. (shrink)

ObjectiveWe wished to explore Parkinson's disease subtypes by clustering analysis based on the multimodal magnetic resonance imaging indices amplitude of low-frequency fluctuation and gray matter volume. Then, we analyzed the differences between PD subtypes.MethodsEighty-six PD patients and 44 healthy controls were recruited. We extracted ALFF and GMV according to the Anatomical Automatic Labeling partition using Data Processing and Analysis for Brain Imaging software. The Ward linkage method was used for hierarchical clustering analysis. DPABI was employed to compare differences in ALFF (...) and GMV between groups.ResultsTwo subtypes of PD were identified. The “diffuse malignant subtype” was characterized by reduced ALFF in the visual-related cortex and extensive reduction of GMV with severe impairment in motor function and cognitive function. The “mild subtype” was characterized by increased ALFF in the frontal lobe, temporal lobe, and sensorimotor cortex, and a slight decrease in GMV with mild impairment of motor function and cognitive function.ConclusionHierarchical clustering analysis based on multimodal MRI indices could be employed to identify two PD subtypes. These two PD subtypes showed different neurodegenerative patterns upon imaging. (shrink)

This essay explores the conception of the individual in Dewey's democratic writings. Following Dewey's lead, I argue that it is human individuality, including our impulses, habits, and capacities, along with an appropriate environment, that represents the uniqueness and power of every individual. In achieving our individuality, we form habits to live and to grow; we strive toward a fully realized human being, while we perform a unique function in keeping the community growing. Dewey's theory of self-construction provides a theoretical foundation (...) for an active-individual as-a-societal-contributor-always-in-the -making that in turn contributes to the improvement of educational opportunities for all people.

The surface grammar of reports such as ‘I have a pain in my leg’ suggests that pains are objects which are spatially located in parts of the body. We show that the parallel construction is not available in Mandarin. Further, four philosophically important grammatical features of such reports cannot be reproduced. This suggests that arguments and puzzles surrounding such reports may be tracking artefacts of English, rather than philosophically significant features of the world.

This study aimed to explore the relationship between job-related stress and township teachers’ professional well-being. Based on Job Demand-Resource Model, this study examined the mediating role of teachers’ professional identity and the moderating role of perceived organizational support in this relationship. A total of 24,276 township teachers in China responded to the Teacher Stress Scale, the Teachers’ Professional Identity Scale, the Teachers’ Professional Well-Being Structure Questionnaire, and the Perceived Organizational Support Scale. Results showed that: the professional well-being of township teachers (...) differed significantly in terms of school type and demographic characteristics like age and gender; job-related stress negatively predicted township teachers’ professional well-being, with teachers’ professional identity playing a mediating role; the relation between job-related stress and teachers’ professional identity was moderated by perceived organizational support; and in the moderated mediation analysis, job-related stress positively predicted township teachers’ professional well-being. These findings indicated that township teachers’ professional well-being was influenced by both organizational and individual factors, which provided a theoretical basis and intervention pathways for improving township teachers’ professional well-being.

Concentrating on the Qingdao Observatory, this paper will explore the role of scientific facility in asserting China’s sovereignty during the first half of the twentieth century. Although scholars have explained the efforts of China’s internationalization in diplomacy through the perspectives of politics, economics and culture, they have not paid attention to science. Therefore, this paper aims to shed some light on how scientific issues were solved via diplomacy during the Republic of China, while further asserting that the focus in negotiations (...) was not confined to science itself, but rather to sovereignty within a scientific context. In this process, the meaning of sovereignty has also been expanded basing on the improvement of nation’s scientific capability. Besides, the participation of different actors involved in sovereignty assertion is investigated by this paper. Although the diplomatic negotiation was held at the international level, the local government and scientific community were main promoters in this case, which calls for attention on the various subjects in sovereignty issue. Consequently, this paper argues that Asian countries, such as Republic of China, could also employ science as a means to negotiate with foreign powers and claim their due rights. (shrink)

Sentiment analysis is one of the important tasks of online opinion analysis and an important means to guide the direction of online opinion and maintain social stability. Due to the multiple characteristics of linguistic expressions, ambiguity, multiple meanings of words, and the increasing speed of new words, it is a great challenge for the task of text sentiment analysis. Commonly used machine learning methods suffer from inadequate text feature extraction, and the emergence of deep learning has brought a turnaround for (...) this purpose. In this paper, we investigate the problem of text sentiment analysis using methods related to deep learning. In order to incorporate user and product information in a more diverse way in the model, this paper proposes a model based on a deep bidirectional long-and short-term memory network-self-attention mechanism-custom classifier. The model first identifies contextual associations and acquires deep text features through a deep bidirectional long- and short-term memory network and then captures important features in the text using a self-attentive mechanism. The model finally combines user information and product information to build a custom classifier module and uses context-aware attention mechanisms to assign specific parameters to user information and product information, which improves the performance of the model on public datasets compared with current common models. The results show that the accuracy of the algorithm in this paper is high, and it is about 5% lower than the traditional algorithm. The method can reduce the number of iterations and the running time of the algorithm. (shrink)

Stress that the exchange of social legacy to what's in store is the main capability of schooling; social qualities should be shown for social turn of events, socialization of the individual and participation of a general public.

With the rapid development of mobile devices, users can now read on the screen. Electronic reading has become a common reading style with the growth in online learning or electronic learning. E-book applications are widely developed and applied for reading on a screen. However, it is difficult for readers to change their reading habits or preference from paper-printed books to digital devices. The study of readers' continuance intention to use e-book APPs is the first step to improving e-reading. This study (...) focuses on the influential factors on undergraduates' continuance intention of e-book APPs, which analyzed and summarized the literature related to the electronic book applications and undergraduates' continuous intention, combined with the characteristics of the e-book APPs, introduced relevant theories and variables, and established the factors that influence undergraduates' continuous intention of using e-book APPs. On this basis, the paper analyzed the relationship between various influencing factors and their influence on continuous intention. A model composed of five hypotheses was constructed to test the factors influencing undergraduates' continuous intention in e-book APPs. The results indicated that of all research variables, satisfaction is the most important factor that affects continuous intention; Perceived usefulness and perceived playfulness have an indirect effect on continuous intention through satisfaction; personalization has direct effects on perceived usefulness and perceived playfulness, so it also has an indirect effect on continuous intention. The findings of the study will be helpful for designers and developers of e-book APPs and provide e-book APP suggestions for readers as well. (shrink)

Wie in anderen Ländern, so galt Einstein auch in China als einer der berühmtesten Wissenschaftler schlechthin. In den siebziger Jahren des 20. Jahrhunderts wurden drei Bände Einstein’scher Schriften zusammengestellt, übersetzt und als Einsteins gesammelte Werke veröffentlicht. Diese Bände dienten lange Zeit vielen Chinesen als Hauptwissensquelle über Einstein; sie übten sogar einen bedeutenden ideologischen Einfluss aus. Im Hintergrund dieses herausgeberischen Projekts standen in der Zeit nach 1949 einflussreiche politische Bewegungen im Zusammenwirken mit wissenschaftskritischen Ansätzen, die ein solches Projekt erst möglich machten (...) und die Textauswahl sowie die Herangehensweise bei der Übersetzung und den Druckvorbereitungen beeinflussten. Unter den Herausgebern und Übersetzern kommt Xu Liangying eine besondere und wichtige Rolle zu, denn er war ursprünglich, vor der Gründung der Republik China, ein Untergrundrevolutionär gewesen. Später wurde er Wissenschaftshistoriker. Es vergingen fast 10 Jahre, bis er die Übersetzung der Einstein’schen Schriften fertigstellen konnte, da er gleichzeitig als Bauer auf dem Lande arbeiten musste und während der „Anti-Rechts-Bewegung” „rechts” stand. Die Übersetzung und Veröffentlichung von Einsteins gesammelten Werken in diesem besonderen soziologischen, kulturellen und politischen Kontext bietet viel Stoff für Rückblicke und Aufarbeitungen aus historischer Perspektive. Vor allem die ideologischen, symbolischen Implikationen in Zusammenhang mit Einstein waren ein dominantes Merkmal jener Zeit. (shrink)

Comme dans les autres pays, Einstein a été l’un des scientifiques les plus célèbres en Chine. Dans les années soixante-dix du 20e siècle, trois volumes des OEuvres complètes d’Einstein ont été traduits et publiés en Chine. Pour de nombreux Chinois ces volumes représentaient une source d’informations sur Einstein et une influence idéologique importante. Le contexte politique en est le suivant: après l’an 1949 des mouvements politiques très influents sont nés en Chine, ayant pour objectif la critique des sciences. Ces mouvements (...) ont beaucoup influencé les décisions, la sélection, le progrès ainsi que la manière de traduire et de publier les oeuvres d’Einstein. Parmi les éditeurs et les traducteurs excellait Xu Liangying. Révolutionnaire clandestin avant la mise en place de la République, il est devenu par la suite historien de la science. Il a investi presque dix ans pour terminer la traduction des oeuvres d’Einstein parce qu’ à l’époque il travaillait comme agriculteur pour ses idées de droite pendant la Révolution culturelle. Dans ce contexte sociologique, culturel et politique, la traduction et la publication des OEuvres complètes d’Einstein offre beaucoup de points qui méritent d’être examinés et analysés dans une perspective historique. Surtout, par exemple, les implications idéologiques, symboliques reliés à Einstein et qui ont été les caractéristiques dominantes de cette époque historique. (shrink)

As in other countries, Einstein has been one of the most famous scientists in China. In 1970’s, the three volumes Collection of Einstein in Chinese have been selected, translated and published, which was the main sources for Chinese people knowing Einstein for long time, and even had important ideological influence. However, as the background of it, in China, there were very influential political movements related to criticism of science after 1949, which also influenced the decision, selection, progress and the way (...) of the translating and publishing of Einstein’s works. Among the editors and translators, XU Liangying was a special and important person, who was originally a underground revolutionist before establishment of the Republic, and latterly became a historian of science. He spent nearly ten years to finish the most translation when he was a real peasant in countryside and a “righty” because of the “anti-righty“ movement. During the translating work and the publication of Collection of Einstein in that special social, cultural and political context then, there were many things worth to look back and analyze their meanings by a historical perspective reflection. Especially, the ideological symbolic implication related to the Einstein has been a very dominant characteristic in the history mentioned here. (shrink)

The well-known paradox between Marxism and morality is that on the one hand, Marx claims that morality is a form of ideology that should be abandoned, while on the other hand, Marx makes quite a few moral judgments in his writings. It is in the research after Marx’s death that the paradox is found, explored and solved. This paper surveys the history of interpreting Marx from the aspect of moral philosophy by dividing it into three sequential phases. Then it presents (...) the research on Marx in each phase, points out conflicting questions within the different periods and puts forward the solution in the end. This paper points out that a philosophical viewpoint based on Marx’s theory of historical materialism is the key to solving the paradox between Marxism and morality. (shrink)

Statements not only update our current knowledge, but also have other dynamic effects. In particular, suggestions or commands ?upgrade' our preferences by changing the current order among worlds. We present a complete logic of knowledge update plus preference upgrade that works with dynamic-epistemic-style reduction axioms. This system can model changing obligations, conflicting commands, or ?regret'. We then show how to derive reduction axioms from arbitrary definable relation changes. This style of analysis also has a product update version with preferences between (...) actions, as well as worlds. Some illustrations are presented involving defaults and obligations. We conclude that our dynamic framework is viable, while admitting a further extension to more numerical ?utility update'. (shrink)

Most theories of slurs fall into one of two families: those which understand slurring terms to involve special descriptive/informational content (however conveyed), and those which understand them to encode special emotive/expressive content. Our view is that both offer essential insights, but that part of what sets slurs apart is use-theoretic content. In particular, we urge that slurring words belong at the intersection of a number of categories in a sociolinguistic register taxonomy, one that usually includes [+slang] and [+vulgar] and always (...) includes [-polite] and [+derogatory]. Thus, e.g., what distinguishes ‘Chinese’ from ‘chink’ is neither a peculiar sort of descriptive nor emotional content, but rather the fact that ‘chink’ is lexically marked as belonging to different registers than ‘Chinese’. It is, moreover, partly such facts which makes slurring ethically unacceptable. (shrink)

Background Respect for patients’ autonomy is usually considered to be an important ethical principle in Western countries; privacy is one of the implications of such respect. Healthcare professionals frequently encounter ethical dilemmas during their practice. The past few decades have seen an increased use of courts to resolve intractable ethical dilemmas across both the developed and the developing world. However, Chinese and American bioethics differ largely due to the influence of Chinese Confucianism and Western religions, respectively, and there is a (...) dearth of comparative studies that explore cases of ethical dilemmas between China and the United States. Methods This paper discusses four typical cases with significant social impact. First, it compares two cases concerning patient privacy: the “Shihezi University Hospital Case”, in which a patient was used as a clinical teaching object without her permission, and the “New York-Presbyterian Hospital Case”, in which the hospital allowed the filming of a patient’s treatment without his consent. Second, it compares two cases regarding patient autonomy and potentially life-saving medical procedures: the “Case of Ms. L”, concerning a cohabitant’s refusal to sign a consent form for a pregnant woman’s caesarean, and the “Case of Mrs. V”, concerning a hospital’s insistence upon a blood transfusion for a dissenting patient. This paper introduces the supporting and opposing views for each case and discusses their social impact. It then compares and analyses the differences between China and the United States from cultural and legislative perspectives. Conclusions Ethical dilemmas have often occurred in China due to the late development of bioethics. However, the presence of bioethics earlier in the US than in China has not spared the US of ethical dilemmas. This paper highlights lessons and inspiration from the cases for healthcare professionals and introduces readers to the role and weight of privacy and autonomy in China and in the US from the perspectives of different cultures, religions and laws.

Despite the productivity of basic cancer research, cancer continues to be a health burden to society because this research has not yielded corresponding clinical applications. Many proposed solutions to this dilemma have revolved around implementing organizational and policy changes related to cancer research. Here I argue for a different solution: a new conceptualization of causation in cancer. Neither the standard molecular biomarker approaches nor evolutionary biology approaches to cancer fully capture its complex causal dynamics, even when considered jointly. These approaches (...) map on to Ernst Mayr’s proximate–ultimate distinction, which is an inadequate conceptualization of causation in biological systems and makes it difficult to connect developmental and evolutionary viewpoints. I propose looking to evolutionary developmental biology to overcome the distinction and integrate the proximate and ultimate causal frameworks. I use the concepts of modularity and evolvability to show how an EvoDevo perspective can be manifested in cancer translational research. This perspective on causation in cancer is better suited for integrating the complexity of current empirical results and can facilitate novel developments in the investigation and clinical treatment of cancer.

Confucianism advocates the lofty moral ideal of “humane love” (ren ai 仁愛) and condemns immoral actions. Strangely enough, however, Mencius, a “paradigmatic Confucian intellectual” who believed that “a true man cannot be corrupted by wealth, subdued by power, or affected by poverty” (Tu 1989a: 15), highly commended such typically corrupt actions as bending the law for the benefit of relatives or appointing people by mere nepotism when he talked about Shun 舜 in the text of the Mencius. In the first (...) four sections of this article, I will address the issue of how Confucianism encourages a special kind of corruption through its fundamentally consanguineous affection. Then, in the remaining sections, I will try to respond to some criticisms of my views by a few Chinese scholars. (shrink)

Let Λ be a singular cardinal of uncountable confinality ψ. Under various assumptions about the sizes of covering families for cardinals below Λ, we prove upper bounds for the covering number cov(Λ, Λ, v⁺, 2). This covering number is closely related to the cofinality of the partial order ([Λ]", ⊆).

On the question of whether the universe should be infinite or finite, there has been throughout the history of physics a struggle between materialism and idealism, between dialectics and metaphysics. Materialism asserts that the universe is infinite, while idealism advocates finitude. At every stage in the history of physics, these two philosophical lines have engaged in fierce struggle. Although developments in physics always demonstrate the failure of the finite universe doctrine, with every new advance in science the idealists distort and (...) take advantage of the latest results of physics to "prove" with varying sleights of hand that the universe is finite, serving the reactionary rule of the moribund exploiting classes. In the early part of this century after the rise of quantum theory and relativity theory, physics arrived at a new stage of development. After General Relativity was announced in 1916, a lot of people used it and similar theories of gravity to produce all sorts of models of the universe. The "finite universe" point of view became even more fashionable. Lenin pointed out that "That certain schools of the new physics have various dealings with Machism and other variants of modern idealism, is a fact not to be doubted for a moment." It is clear from reading all sorts of foreign literature that the schools of physics promoting a finite universe are linked up with all sorts of idealist philosophy, including theology. (shrink)

Shun argues that the distinction between first and third person is ill-suited to explain the complexities of anger. In this commentary, I first argue that, while the distinction is not uniquely important in characterizing anger and its variations, it can be distinctively important in illuminating the nature and normative significance of different forms of anger. Indeed, Shun’s own characterizations of anger in the paper seem to presuppose this importance. Secondly, I show that there are two related but distinct ways in (...) which one’s anger is ‘personally involved’: the first concerns how the offence is registered (e.g., whether it is perceived as targeting oneself), and the second concerns one’s emotional uptake of the offence. Lastly, I propose an alternative interpretation of Zhu Xi’s distinction between anger that ‘resides in things’ and anger that ‘resides in the self’, where the emphasis is not on whether anger is an appropriate response to a situation but on whether anger is properly encapsulated.
