A terahertz frequency-modulated continuous wave imaging radar system is developed for high-resolution 3D imaging recently. Aiming at the problems of long data acquisition periods and large sample sizes for the developed imaging system, an algorithm based on compressed sensing is proposed for THz FMCW radar 3D imaging in this paper. Firstly, the FMCW radar signal model is built, and the conventional range migration algorithm is introduced for THz FMCW radar imaging. Then, compressed sensing is extended for THz FMCW radar 3D (...) imaging, and the Newton smooth L0-norm algorithm is presented for sparse measurement data reconstruction. Both simulation and measurement experiments demonstrate the feasibility of reconstructing THz images from measurements even at the sparsity rate of 20%. (shrink)

There is controversy as to whether children with developmental language disorder (DLD) and those with high-functioning autism plus language impairment (HFA-LI) share similar language profiles. This study investigated the similarities and differences in the production of Chinese negative sentences by children with DLD and children with HFA-LI to provide evidence relevant to this controversy. The results reflect a general resemblance between the two groups in their lower-than-TDA (typically developing age-matched) performance. Both groups encountered difficulties in using negative markers, which suggests (...) that they might be impaired in feature agreement. Slight differences were detected between the two groups. Specifically, children with DLD experienced difficulties with the agreement on the feature [+telic] and that on the feature [+dynamic], while children with HFA-LI had difficulties with the agreement on the feature [+dynamic] and that on the feature [−dynamic]. This study supports the idea of a common symptomatology for the two disorders. More importantly, it suggests that these two disorders, DLD and HFA-LI, are not altogether the same in terms of language impairment. This paper concludes that general labels should not be simply attached to any children with language disorders. Instead, atypical language is very worthy of further analysis in the categorization of language disorders. (shrink)

In this paper, I introduce an intrinsic account of the quantum state. This account contains three desirable features that the standard platonistic account lacks: (1) it does not refer to any abstract mathematical objects such as complex numbers, (2) it is independent of the usual arbitrary conventions in the wave function representation, and (3) it explains why the quantum state has its amplitude and phase degrees of freedom. -/- Consequently, this account extends Hartry Field’s program outlined in Science Without Numbers (...) (1980), responds to David Malament’s long-standing impossibility conjecture (1982), and establishes an important first step towards a genuinely intrinsic and nominalistic account of quantum mechanics. I will also compare the present account to Mark Balaguer’s (1996) nominalization of quantum mechanics and discuss how it might bear on the debate about “wave function realism.” In closing, I will suggest some possible ways to extend this account to accommodate spinorial degrees of freedom and a variable number of particles (e.g. for particle creation and annihilation). -/- Along the way, I axiomatize the quantum phase structure as what I shall call a “periodic difference structure” and prove a representation theorem as well as a uniqueness theorem. These formal results could prove fruitful for further investigation into the metaphysics of phase and theoretical structure. -/- (For a more recent version of this paper, please see "The Intrinsic Structure of Quantum Mechanics" available on PhilPapers.).

Our understanding of the complexity of the oral biome and of the role of the various constituent bacteria in the aetiology of dental disease is growing. Probiotics and their relationship with prebiotics, as well as other microbiome‐based interventions, could be useful in preventing and treating dental disease and in promoting oral health. However, given the promise and early stage of this treatment approach, there are also a number of ethical, social and regulatory issues associated with innovative probiotic therapy. In this (...) article, a brief update is given on contemporary theories of the aetiology and management of the two commonest dental diseases, and on the roles of pre‐ and probiotics and oral biome transplant in the management of these diseases. The focus is primarily on four core issues: informed consent, risk–benefit assessment, how to determine suitable healthy donors, and commercialization and regulation. We discuss the safety and benefits of oral probiotics, not only concerning the products and quality control during their manufacture, but also regarding the depth of public knowledge about this topic. We point out that the requirement of listing ingredients honestly might be insufficient, and that the prevalent rhetoric of ‘natural’ and ‘organic’ as well as some health claims in the translational, innovative probiotic industry and markets are themselves misleading and should be carefully scrutinized. Finally, we suggest an ethical imperative to find a balance between scientific research and industry, and public health in the regulation of probiotics. (shrink)

In this study, we propose and test the relationship between CSR and firm financial performance, how this relationship differs between firms led by CEOs with political connections and those led by CEOs without political connections, and how this relationship differs between state-owned firms and nonstate-owned firms. Based on a sample of 1645 Chinese listed firms during the period 2011 and 2020 (inclusive), we find that CSR has an inverted U-shaped relationship with firm financial performance. As the level of CSR increases (...) from slight to moderate, CSR is positively related to firm performance; as the level of CSR increases from moderate to great, CSR is negatively related to firm financial performance. Additionally, we find that this inverted U-shaped relationship differs between firms led by CEOs with political connections and those led by CEOs without political connections and differs between state-owned firms and nonstate-owned firms. That is, both the synergic effect (positive effect) of CSR on firm financial performance when the level of CSR is low and the competitive effect (negative effect) of CSR on firm financial performance when the CSR is high are more pronounced for firms led by CEOs without political connections and nonstate-owned firms than for firms led by CEOs with political connections and state-owned firms. The theoretical and managerial implications of these findings are discussed. (shrink)

The intracellular multiprotein complex β‐catenin destruction complex plays a key role in Wnt/β‐catenin signaling. Wnt stimulation induces the assembly of the receptor‐associated signalosome and the inactivation of the destruction complex, leading to β‐catenin accumulation and transcriptional activation of the target genes. The core components of the destruction complex include Axin, APC, GSK3β, CK1α and other proteins. Recent studies demonstrated that Axin and APC undergo liquid–liquid phase separation (LLPS), which is critical for their function to regulate Wnt/β‐catenin signaling. Here, we discuss (...) the possible roles of LLPS in Wnt/β‐catenin signaling and regulation of Axin LLPS by post‐translational modifications. (shrink)

Due in large part to the trends towards economic globalization, English has become the most widely disseminated and ubiquitous international language. The purpose of the study was to investigate what Taiwan?s EFL teachers at the elementary level believe about the policy of English as a compulsory subject and how they perceive the benefits and obstacles of the policy?s implementation. Ten elementary English teachers in Tainan City and its suburban areas participated in this study. Data were collected through teachers? interviews, classroom (...) observation and document analysis. Results found that all ten teachers agreed with the policy for English as a compulsory subject at the elementary level. They observed both positive and negative sides of this top?down policy. Classroom observation and interview data revealed that EFL teachers had to plan their English classes with the constraints on a large class of students with mixed levels of proficiency, limited teaching hours and resources. Parents? expectations of and attitudes towards English learning also became an obstacle. (shrink)

The present study investigated whether another individual’s gaze direction influences an observer’s affective responses. In Experiment 1, subjective self-ratings and an affective priming paradigm were employed to examine how participants explicitly and implicitly, respectively, evaluated the affective valence of direct gaze, averted gaze, and closed eyes. The explicit self-ratings showed that participants evaluated closed eyes more positively than direct gaze. However, the implicit priming task showed an inverse pattern of results indicating that direct gaze was automatically evaluated more positively than (...) closed eyes were. Experiment 2 confirmed that the opposite patterns of results between the two tasks were not due to differences in presentation times of the gaze stimuli. The results provide evidence for automatic affective reactions to eye gaze and indicate a dissociation between explicit and implicit affective evaluations of eyes and gaze direction. (shrink)

Computer Science and Artificial Intelligence will be the twenty-first century logic development of the main power source, and in the twenty-first century will largely determine the face of logic. At least in the early twenty-first century, logic will focus on the following topics: how to deal with common sense reasoning in the logic of Eph coordination, non-monotonic and fault tolerance factors? how to make robots with human intelligence and creativity, as established from the empirical evidence used to guide future action (...) in the induction of judgments can be wrong? how the knowledge representation and knowledge reasoning, in particular, is based on the existing knowledge base and between the cognitive subject knowledge and the reasoning? how contextual factors, combined with a variety of natural language understanding and reasoning, so that intelligent robots to employing natural language for successful communication with people? . . . .

Traditional Qiang culture is the sum of all civilizations created by Qiang people in the long historical development of the national minority, and is an important component of Chinese civilization. However, traditional Qiang culture suffered from the attack of the great 5.12 Wenchuan Earthquake in the more and more vigorous process of industralization and globalization nowadays. Based on difficulties and problems encountered in post-disaster reconstruction for cultural preservation and development, this article takes into an overall consideration of Qiang traditional cultural (...) preservation and post-disaster reconstruction, protection of nonphysical cultural heritage and national cultural resources, tries to explore the principle, approach and method of traditional Qiang cultural preservation and development and attempts to present the current situation and analyze problems, and accordingly puts forward some countermeasures, measures and specific projects with the features of scientificalness, maneuverability and development.

In recent years, while extensive researches on various networks properties have been proposed and accomplished, little has been proposed and done on network robustness and node vulnerability assessment under cascades in directed large-scale online community networks. In essential, an online directed social network is a group-centered and information spread-dominated online platform which is very different from the traditional undirected social network. Some further research studies have indicated that the online social network has high robustness to random removals of nodes but (...) fails to the intentional attacks, particularly to those attacks based on node betweenness or node directed coefficient. To explore on the robustness of directed social network, in this article, we have proposed two novel node centralities of ITG and I M p v. These two new centrality models are designed to capture this cascading effect in directed online social networks. Furthermore, we also propose a new and highly efficient computing method based on iterations for I M p v. Then, with the abundant experiments on the synthetic signed network and real-life networks derived from directed online social media and directed human mobile phone calling network, it has been proved that our ITG and I M p v based on directed social network robustness and node vulnerability assessment method is more accurate, efficient, and faster than several traditional centrality methods such as degree and betweenness. And we also have proposed the solid reasoning and proof process of iteration times k in computation of I M p v. To the best knowledge of us, our research has drawn some new light on the leading edge of robustness on the directed social network. (shrink)

Replication protein A (RPA) is the main eukaryotic single‐stranded DNA (ssDNA) binding protein, having essential roles in all DNA metabolic reactions involving ssDNA. RPA binds ssDNA with high affinity, thereby preventing the formation of secondary structures and protecting ssDNA from the action of nucleases, and directly interacts with other DNA processing proteins. Here, we discuss recent results supporting the idea that one function of RPA is to prevent annealing between short repeats that can lead to chromosome rearrangements by microhomology‐mediated end (...) joining or the formation of hairpin structures that are substrates for structure‐selective nucleases. We suggest that replication fork catastrophe caused by depletion of RPA could result from cleavage of secondary structures by nucleases, and that failure to cleave hairpin structures formed at DNA ends could lead to gene amplification. These studies highlight the important role RPA plays in maintaining genome integrity. (shrink)

Drug abuse has been and continues to be, a common social issue worldwide, yet the efficiency of widely adopted sweeping speech for anti-drug campaigns has proven inefficient. To provide students with a safe and efficient learning situation related to drug refusal skills, we used a novel approach rooted in a serious learning game and concept map during a brief extracurricular period to help students understand drugs and their negative effects. The proposed game-based situational learning system allowed all students to participate (...) simultaneously and individually in multiple scenarios of drug temptation posed by peers and classmates to practice responding and refusing drugs in school and community settings. Moreover, to explore whether different personality traits result in different anti-drug responses, we used a serious game to conduct an anti-drug experiment on 53 junior middle school students aged 13–15. Each participant’s decision-making process was recorded in the serious game as behavioral patterns for lag sequential analysis. The outcomes revealed seven behavioral patterns including differentiation, acceptance, effective and ineffective responses, effective and ineffective solution-seeking, and failure to refuse. The GSEQ which is a computer program for analyzing sequential observational data was used. The results indicated the following: Neuroticism was performed at a relatively low level under the guidance of a concept map. “Neuroticism” was associated with the lowest risk of accepting drugs. Students with “openness to experiences” were at high risk of accepting drugs. Almost all personality behavioral transition diagrams showed that failure to refuse drugs was followed by inefficient seeking of help and inefficient refusal. These findings provide reference points for designing adaptive anti-drug education programs. (shrink)

Teacher education students, as an important reserve in the field of education, their growth and development are related to the future of science, economy, sustainable development of education. Through participation in the educational practice of STEAM, which integrates science, technology, engineering, art, and mathematics is more beneficial for them to acquire 21st century skills like communication, collaboration, learning innovation and critical thinking. However, little has been seen about the use and effectiveness of short videos in STEAM education activities and how (...) they can be used to support and promote teacher education students STEAM learning performance and sustainable inquiry behaviors. Therefore, this study combines the framework of triadic reciprocity determinism theory and technology acceptance theory to propose six research hypotheses and develop a research model to explore the relationship between collaborative self-efficacy, perceived usefulness of short videos, perceived ease of use, STEAM learning performance and teacher education students’ sustainable inquiry behavior. To achieve the purpose of this study, this study used purposive sampling and invited teacher education students from five classes of preschool education at a university in Guangxi Zhuang Autonomous Region, China, to participate in this study. A total of 8 h of instructional guidance was provided over a four-week period, in which participants used short videos for collaborative group learning and independent inquiry and applied STEAM concepts to kindergarten science activities. Participants’ STEAM performance was measured and surveyed during the fourth week. The results of the study validation showed that teacher education students CS-E had a positive effect on the PU and PEOU of short videos; Teacher’s education students PEOU of short videos had a positive effect on usefulness; Teacher’s education students PU and PEOU of short videos had a positive effect on STEAM learning performance; Teacher’s education students’ STEAM learning performance had a positive effect on sustainable inquiry behavior.

The long-running discourse on respect for human dignity and autonomy in the physician-patient relationship pertaining to persons with dementia (PwDs) is explored deeply in this paper through the use of a real-life case, to highlight the complex interplay between autonomy and best interest when it comes to a PwD's experiential and critical interests. Many scenarios and perspectives are described and applies to the case. However, there are a few perspectives, which are touched upon that could do with further scrutiny. Firstly, (...) it has been argued that rigid adherence to the advance directives of PwDs means that PwDs will be the only people who are not allowed to ever change their minds. This withdrawal of a fundamental freedom hardly accords with respect for human dignity, or for any residual autonomy that these individuals may still enjoy. Secondly, viewing this case through the lens of care ethics, and incorporating the recently proposed conceptual framework of anthropological vulnerability, may reveal valuable insights regarding care provision and caring physician-patient relationships. These perspectives would analyse the role of relational ontology, particularly in relation to significant others, significant communities, and caregivers. (shrink)
