We propose a fast and reliable corner detector that can detect corners under non-uniform illumination and fuzzy mineshaft images effectively. First, we presented an inner mask that used only four pixels to determine the flat and corner regions of an image, which could eliminate unnecessary computation of flat regions, thus reducing computing cost. Second, we separated the corner regions into background and foreground and computed the separate corner threshold to settle non-uniform illumination. Third, we proposed a fast corner-detection algorithm to (...) compute the nucleus continuous contributive segment based on the corner state. Finally, we proposed two effective methods to remove the false corners. Experimental results showed that our approach has a better detection quality and is less time consuming than three other algorithms on an artificial image, a noisy image, and non-uniform images and could meet the real-time requirement of mineshaft applications.

This work explores the importance of similarity-based processes in human everyday reasoning, beyond purely rule-based processes prevalent in AI and cognitive science. A unified framework encompassing both rulebased and similarity-based reasoning may provide explanations for a variety of human reasoning data.

BackgroundChildhood experiences can exert a huge impact on adult psychological conditions. Previous studies have confirmed the effects of adverse childhood experiences and benevolent childhood experiences on psychological distress separately, but few studies explored a combined effect of ACEs and BCEs on psychological distress. The aim of this study was to explore a combined effect of ACEs and BCEs on psychological distress among Chinese undergraduates.MethodsParticipants were undergraduates aged 17–24 years and completed a self-reported questionnaire. A series of regression analyses were conducted (...) to examine the association between childhood experiences and psychological distress.ResultsA total of 65.7% of undergraduates had BCEs, 27.1% of undergraduates had ACEs, and 12.9% of undergraduates had ACEs and BCEs simultaneously. Logistic regression analysis indicated that undergraduates who experienced high ACEs were more likely to have a high risk of psychological distress [odds ratio = 1.46, 1.84, and 3.15 for uncertainty stress, depressive symptoms, and suicidal ideation, respectively], while undergraduates who experienced High BCEs were less likely to have psychological distress compared with Low-Both group. The combined effect of ACEs and BCEs could also play as a protective factor in uncertainty stress and depressive symptoms.ConclusionOur findings suggested that ACEs and BCEs could not only predict the psychological distress independently, but also BCEs could counteract the negative effect of ACEs in psychological problems. There is an even greater need to identify and support the victims of ACEs and to increase BCEs in early childhood. (shrink)

Screen time has become a hot button issue in psychology with researchers fiercely debating its mental effects. If we want to understand the psychological dynamics of technology use, however, a numerical conceptualization of screen time will lead us to gloss over crucial distinctions. To make this point, the present article takes a hermeneutic approach to a negative form of screen time known as ‘phubbing’, which is the practice of snubbing conversational partners in favor of one’s phone. Using interview data, it (...) is demonstrated that whether or not phone use amounts to phubbing, that is, whether or not it tips over and becomes harmful, depends on a host of contextual factors such as relation (who), content (what), purpose (why), timing (when), and communication (how). These findings demonstrate that not all screen time is created equal: what is harmful and inappropriate in one context is benign in another, and vice versa. Simply put, screen time is not a numerical entity whose causal effects we can measure and explain, but a meaningful activity that we must try to understand. (shrink)

Non‐coding centromeres, which dictate kinetochore formation for proper chromosome segregation, are extremely divergent in DNA sequences across species but are under active transcription carried out by RNA polymerase (RNAP) II. The RNAP II‐mediated centromeric transcription has been shown to facilitate the deposition of the centromere protein A (CENP‐A) to centromeres, establishing a conserved and critical role of centromeric transcription in centromere maintenance. Our recent work revealed another role of centromeric transcription in chromosome segregation: maintaining centromeric cohesion during mitosis. Interestingly, this (...) role appears to be fulfilled through ongoing centromeric transcription rather than centromeric transcripts. In addition, we found that centromeric transcription may not require some of the traditional transcription initiation factors, suggestive of “uniqueness” in its regulation. In this review, we discuss the novel role and regulation of centromeric transcription as well as the potential underlying mechanisms. (shrink)

This book addresses an often-ignored theme in the mission of the current Chinese education reform: cultivating students’ individuality as a foundation of learning. Moreover, it tries to revive the Confucian tradition of self-cultivation while building a connection with the western idea of individuality to provide a meaningful resource for the current reform of Chinese education.

Edward Conze suggested that the first two chapters of the Ratnaguṇa (hereafter “the 41 verses”) were the earliest Mahāyāna text. Yet the origin of the verses and their relationship with other prajñāpāramitā texts have been murky. Through five levels of analysis, this research argues that the 41 verses were most likely the verse section of the Sūtra of Mahā-prajñāpāramitā Pronounced by Mañjuśrī Bodhisattva (SMPMB) and later became independent and expanded. The five levels of analysis are as follows. First, the Mahāyāna (...) origin narratives, the Mahāyāna sutras, and ancient Indian Buddhist art all point to Mañjuśrī as the most likely architect of the prajñāpāramitā doctrine. Second, as an early Mahāyāna text, the SMPMB’s narrative shows that Mañjuśrī pronounced prajñāpāramitā and the Buddha sanctioned it. Third, the Tibetan Ratnaguṇa bears the line “Homage to Holy Mañjuśrī” in its beginning, and the text is usually found in conjunction with “The Recitation of Mañjuśrī’s Attributes.” Lexical items also show high parallelism between the 41 verses and the SMPMB. Fourth, a semantic intertextual analysis demonstrates full and complete intertextuality between the two texts. That is, the two texts can fully annotate each other. Finally, a content analysis of the references to the “one four-line verse” (yi si ju ji 一四句偈) in Mahāyāna texts indicates that it is most likely a corrupted reference to the 41 verses. The research further notes that intertextuality between the 41 verses and other prajñāpāramitā sutras cannot provide explanations for the observations in the above analysis, thus excluding alternative explanations. Finally, the research notes that how to attain wisdom deliverance was a widely explored subject from the Buddha’s time to the early schools. Mañjuśrī’s prajñāpāramitā doctrine is the most sophisticated interpretation of the Buddha’s teaching on “see things as they really are” and thus constituted the foundation of early Mahāyāna Buddhism.
