摘要：
The super tau-charm facility (STCF) is an electron-positron collider proposed by the Chinese particle physics community. It is designed to operate in a center-of-mass energy range from 2 to 7 GeV with a peak luminosity of 0.5 x 1035 cm-2 center dot s-1 or higher. The STCF will produce a data sample about a factor of 100 larger than that of the present tau-charm factory - the BEPCII, providing a unique platform for exploring the asymmetry of matter-antimatter (charge-parity violation), in-depth studies of the internal structure of hadrons and the nature of non-perturbative strong interactions, as well as searching for exotic hadrons and physics beyond the Standard Model. The STCF project in China is under development with an extensive R&D program. This document presents the physics opportunities at the STCF, describes conceptual designs of the STCF detector system, and discusses future plans for detector R&D and physics case studies.

摘要：
Elevation is an uplifting feeling evoked by witnessing other’s moral beauty. Prior studies explored the impact of different aspects of completed moral acts on elevation. However, whether intended or completed moral acts have a greater impact on observers’ elevation remains unclear. We hypothesize that intended moral acts evoke greater elevation in observers than completed ones. A total of 437 Chinese participants rated their elevation after reading manipulated descriptions about actors’ moral acts in three online experiments. The results consistently supported our hypothesis. Moreover, the results of moderated mediation models showed that actors’ moral potential mediated the effect of moral acts on elevation. Female observers exhibited stronger responses to intended moral acts than male observers. In addition, observers’ elevation influenced their willingness to cooperate with the actors. Implications for elevation elicitation and future directions are discussed.

摘要：
A visible-light-induced brominated spirocyclization of N-arylpropiolamides and CBr4 for the synthesis of 3-bromo-azaspiro[4,5]trienones is reported here. This process allows the formation of C–Br, C–C, and C=O bonds in a single reaction via a cascade radical addition/ipso-cyclization/oxidative dearomatization sequence. This protocol also features high functional group tolerance, operational simplicity and the use of molecular oxygen as an oxidant as well as sustainable photocatalyst- and additive-free reaction conditions at room temperature. Meanwhile, the presented straightforward and sustainable strategy has also been applied to the synthesis of several biologically active compounds.

摘要：
This study examines the relationship between natural resource rents and economic growth in Asian economies from 1990 to 2021, considering the impact of electricity generated from renewable sources, access to clean fuel technology, and research and development expenditures. The study uses time series data and employs the Bayer-Hanck cointegration analysis to examine long-term cointegration, along with least squares with known structural breaks for the main estimates and robust least squares method for the analysis. The findings suggest that access to clean fuel technology, natural gas rents, and oil rents significantly impact economic expansion without renewable electricity, while mineral rents have insignificant results. Including electricity from renewable energy, access to clean fuel technology, oil rents, and research and development expenditures suggest a positive association with economic growth. In contrast, natural gas rents and mineral rents produce negative results. The study concludes that there is an asymmetric relationship between natural resources and economic growth in the studied Asian economies. The study highlights the importance of effectively utilizing natural resources and promoting renewable energy in Asian economies with natural resource wealth to promote economic growth.

摘要：
The transverse momentum (p(T)) and centrality dependence of the nuclear modification factor R-AA of prompt and non-prompt J/psi, the latter originating from the weak decays of beauty hadrons, have been measured by the ALICE collaboration in Pb-Pb collisions at root s(NN) = 5.02TeV. The measurements are carried out through the e(+)e(-) decay channel at midrapidity (vertical bar y vertical bar < 0.9) in the transverse momentum region 1.5 < p(T) < 10 GeV/c. Both prompt and non-prompt J/psi measurements indicate a significant suppression for p(T) > 5 GeV/c, which becomes stronger with increasing collision centrality. The results are consistent with similar LHC measurements in the overlapping pT intervals, and cover the kinematic region down to p(T) = 1.5 GeV/c at midrapidity, not accessible by other LHC experiments. The suppression of prompt J/psi in central and semicentral collisions exhibits a decreasing trend towards lower transverse momentum, described within uncertainties by models implementing J/psi production from recombination of c and (c) over bar quarks produced independently in different partonic scatterings. At high transverse momentum, transport models including quarkonium dissociation are able to describe the suppression for prompt J/psi. For non-prompt J/psi, the suppression predicted by models including both collisional and radiative processes for the computation of the beauty-quark energy loss inside the quark-gluon plasma is consistent with measurements within uncertainties.

摘要：
Previous research has conducted extensive work on the impact of social network site (SNS) use on depression. However, most of these studies have focused on adolescents or adults, and little is known about how SNS use affects depression among children. Based on the vulnerability model of depression, the self-system beliefs model, and the risk-buffering hypothesis, we examined whether self-esteem would mediate the relationship between SNS use and children's depression and whether self-compassion would play a moderating role in the mediating process. The sample consisted of 386 Chinese children from grades three to six (Mage = 9.83 years, SD = 1.23; 42.5 % girls), who provided self-reported data on demographic variables, SNS use, self-esteem, depression, and self-compassion. Results indicated that after controlling for the children's gender and age, the partial mediating role of self-esteem between SNS use and depression was significant at low levels of self-compassion, marginally significant at high levels, and non-significant at mean levels. Moreover, both the first and second stages of the indirect effects were moderated by self-compassion. Specifically, the effects of SNS use on self-esteem were negative, non-significant, and marginally positive for children with low, middle, and high self-compassion, respectively. The interaction pattern of self-esteem and self-compassion on depression fit the protective-attenuating hypothesis: the protective effect of self-compassion was stronger for children with low self-esteem. This study extends our understanding of the underlying mechanisms linking SNS use to depression among children, which has both theoretical and practical implications for interventions for children's depressive symptoms. The limitations and theoretical and practical implications of this study are discussed.
摘要：
Let
$$A\in M_2({\mathbb {Z}})$$
be an expanding integer matrix and
$$D=\{d_1={\textbf{0}},d_2,d_3\}\subset {\mathbb {Z}}^2$$
. It follows from Hutchinson (Indiana Univ Math J 30:713–747, 1981) that the generalized Sierpinski self-affine set
$${\textbf{T}}(A,D)$$
is the unique compact set determined by the pair (A,D) satisfing the set-valued equation
$$A{\textbf{T}}(A,D)=\bigcup _{i=1}^3({\textbf{T}}(A,D)+d_i)$$
. In this paper, we show that Fuglede’s conjecture holds on
$${\textbf{T}}(A,D)$$
, which states that
$${\textbf{T}}(A,D)$$
is a spectral set if and only if
$${\textbf{T}}(A,D)$$
is a translational tile. For the classical Sierpinski self-affine set
$${\textbf{T}}(A,D_{c})$$
with
$$D_{\text {c}}=\{(0,0)^t,(1,0)^t, (0,1)^t\}$$
, a finer characterization of tiling set is given. As an application, we find that the classical Sierpinski self-affine tile
$${\textbf{T}}(A,D_{\text {c}})$$
is suitable for Kolountzakis’ conjecture on product domain. This enriches the results that are now known.

Key-frame extraction;Audiovisual interaction and fusion;Attention mechanism;Emotion recognition;Intra-modality interaction;Cross-modality interaction
摘要：
Purpose - Although numerous signal modalities are available for emotion recognition, audio and visual modalities are the most common and predominant forms for human beings to express their emotional states in daily communication. Therefore, how to achieve automatic and accurate audiovisual emotion recognition is significantly important for developing engaging and empathetic human-computer interaction environment. However, two major challenges exist in the field of audiovisual emotion recognition: (1) how to effectively capture representations of each single modality and eliminate redundant features and (2) how to efficiently integrate information from these two modalities to generate discriminative representations.Design/methodology/approach - A novel key-frame extraction-based attention fusion network (KE-AFN) is proposed for audiovisual emotion recognition. KE-AFN attempts to integrate key-frame extraction with multimodal interaction and fusion to enhance audiovisual representations and reduce redundant computation, filling the research gaps of existing approaches. Specifically, the local maximum-based content analysis is designed to extract key-frames from videos for the purpose of eliminating data redundancy. Two modules, including "Multi-head Attention-based Intra-modality Interaction Module" and "Multi-head Attention-based Cross-modality Interaction Module", are proposed to mine and capture intra- and cross-modality interactions for further reducing data redundancy and producing more powerful multimodal representations.Findings - Extensive experiments on two benchmark datasets (i.e. RAVDESS and CMU-MOSEI) demonstrate the effectiveness and rationality of KE-AFN. Specifically, (1) KE-AFN is superior to state-of-the-art baselines for audiovisual emotion recognition. (2) Exploring the supplementary and complementary information of different modalities can provide more emotional clues for better emotion recognition. (3) The proposed key-frame extraction strategy can enhance the performance by more than 2.79 per cent on accuracy. (4) Both exploring intra- and cross-modality interactions and employing attention-based audiovisual fusion can lead to better prediction performance.Originality/value - The proposed KE-AFN can support the development of engaging and empathetic human-computer interaction environment.

Signed mixed graph;Eisenstein matrix;Spectral radius
摘要：
A mixed graph M-G is obtained from a simple graph G by orienting an edge subset of G. A signed mixed graph is a mixed graph with arcs and edges signed + or -. The unit Eisenstein matrix (epsilon-matrix for short) of a signed mixed graph was recently introduced by Wissing and van Dam [32]. This novel matrix is indexed by the vertices of the signed mixed graph, and the entry corresponding to a positive arc from u to v is equal to omega = 1+i root 3/2 (and its symmetric entry is (omega) over bar = 1-i root 3/2); the entry corresponding to a negative arc is equal to -omega (and its symmetric entry is -(omega) over bar); the entry corresponding to a positive edge is equal to 1; the entry corresponding to a negative edge is equal to -1; and 0 otherwise. In this paper, we study the spectral properties of this epsilon-matrix. We characterize all the signed mixed graphs whose eigenvalues are contained in (-alpha, alpha) for alpha is an element of {root 2, root 3, root 2} .(c) 2023 Elsevier B.V. All rights reserved.

摘要：
After aging in the environment, some nanoplastics will carry different charges and functional groups, thereby altering their toxicological effects. To evaluate the potential impact of aging of nanoplastics on the mammalian reproductive system, we exposed C57BL/6 male mice to a dose of 5mg/kg/d polystyrene nanoparticles (PS-NPs) with different functional groups (unmodified, carboxyl functionalized and amino functionalized) for 45days for this study. The results suggest that PS-NPs with different functional groups triggered oxidative stress, a decreased in the testis index, disruption of the outer wall of the seminiferous tubules, reduction in the number of spermatogonia cells and sperm counts, and an increased in sperm malformations. We performed GO and KEGG enrichment analysis on the differentially expressed proteins, and found they were mainly enriched in protein transport, RNA splicing and mTOR signaling. We confirmed that the PI3K-AKT-mTOR pathway is over activated, which may lead to reduction of spermatogonia stem cells by over differentiation. Strikingly, PS-NPs with functional group modifications are more toxic than those of unmodified polystyrene, and that PS-NPs with positively charged amino modifications are the most toxic. This study provides a new understanding for correctly evaluating the toxicological effects of plastic aging, and of the mechanism responsible for the reproductive toxicity caused by nanoplastics.
摘要：
Upland cotton, the mainly cultivated cotton species in the world, provides over 90% of natural raw materials (fibers) for the textile industry. The development of cotton fibers that are unicellular and highly elongated trichomes on seeds is a delicate and complex process. However, the regulatory mechanism of fiber development is still largely unclear in detail. In this study, we report that a homeodomain-leucine zipper (HD-ZIP) IV transcription factor, GhHOX4, plays an important role in fiber elongation. Overexpression of GhHOX4 in cotton resulted in longer fibers, while GhHOX4-silenced transgenic cotton displayed a "shorter fiber" phenotype compared with wild type. GhHOX4 directly activates two target genes, GhEXLB1D and GhXTH2D, for promoting fiber elongation. On the other hand, phosphatidic acid (PA), which is associated with cell signaling and metabolism, interacts with GhHOX4 to hinder fiber elongation. The basic amino acids KR-R-R in START domain of GhHOX4 protein are essential for its binding to PA that could alter the nuclear localization of GhHOX4 protein, thereby suppressing the transcriptional regulation of GhHOX4 to downstream genes in the transition from fiber elongation to secondary cell wall (SCW) thickening during fiber development. Thus, our data revealed that GhHOX4 positively regulates fiber elongation, while PA may function in the phase transition from fiber elongation to SCW formation by negatively modulating GhHOX4 in cotton.

Facial expression intensity estimation;Ordinal regression;Label distribution learning;Semi-supervised
摘要：
Facial expression intensity estimation has promising applications in health care and affective computing, such as monitoring patients’ pain feelings. However, labeling facial expression intensity is a specialized and time-consuming task. Ordinal regression (OR)-based methods address this issue to some extent by estimating the relative intensity but failing to estimate the absolute intensity due to lack of exploring useful information from noisy labels caused by manual and automatic labeling biases. Inspired by label distribution learning (LDL) to resist the noisy labels, this paper introduces the label-distribution-learning-enhanced OR (LDL-EOR) approach for facial expression intensity estimation. This design aims to utilize LDL to improve the accuracy of absolute intensity estimation while keeping the cost of manual labeling low. The label distribution is converted into a continuous intensity value by calculating the mathematical expectation, which makes the prediction results meet both relative and absolute intensity constraints. Ensuring the feasibility of LDL-EOR in different supervised settings, this paper presents a unified label distribution generation framework to automatically relabel training data frame by frame. The generated soft labels are used to supervise the LDL-EOR model and enhance its robustness to the noise existing in the original labels. Numerous experiments were conducted on three public expression datasets (CK+, BU-4DFE, and PAIN) to validate the superiority of LDL-EOR relative to other state-of-the-art approaches.
摘要：
Abstract Considerable research has been dedicated to studying teachers' digital competence, yet limited insights have been gained regarding its impact on online teacher autonomy support. Based on the Technological Pedagogical Content Knowledge (TPACK) framework, this study utilized a multiple regression analysis model to explore how teachers' digital competence affects online teacher autonomy support. Drawing on data from 652 Chinese primary school teachers, the study revealed that teachers' digital competence positively influenced online teacher autonomy support via teachers' cognitive empathy. Teachers' emotional empathy strengthened the direct effect of cognitive empathy on online teacher autonomy support, and its indirect effect on teachers' digital competence on online teacher autonomy support. The findings inform TPACK framework development and practical considerations in online teaching, deepening understanding of the impact of digital competence on online teacher autonomy support.Practitioner notesWhat is already known about this topic Previous research has recognized the importance of teachers' digital competence in supporting learners' autonomy and enhancing their online learning experiences. Existing studies have explored different dimensions of teachers' digital competence, including technological proficiency, pedagogical knowledge and content expertise. Studies have also examined the role of empathy in online teaching and learning, emphasizing its importance in fostering positive teacher–student relationships and promoting student engagement and motivation. What this paper adds This study introduces digital competence as a novel and comprehensive assessment of technology integration in teaching, bridging an existing gap in the literature. This study recognizes the importance of socio‐emotional skills in online teaching by including teachers' empathic traits within the expanded TPACK framework. Teachers' cognitive empathy acts as a mediator and emotional empathy functions as a moderator in the relationship between digital competence and online teacher autonomy support, offering new insights into the underlying mechanisms. Implications for practice and/or policy Teacher educators should find ways to support teachers' digital competence in facilitating learners' autonomy in online learning environments effectively. Teacher educators should incorporate teacher empathy development into teachers' professional development programmes for online teaching, offering tailored interventions to differentiate and enhance both cognitive and emotional empathy.

摘要：
Kinematics restricts the ability of rare charm decays to explore the charged lepton-flavor-violation processes mediated by the quark-level c→uℓτ transition. To fill the gap, we propose exploring new physics (NP) through the quasielastic scattering process e−p→τ−Λc and the polarization of the τ lepton. As analyzing modes for the τ polarization, we consider the decays τ−→π−ντ , τ−→ρ−ντ , and τ−→ℓ−ν¯ℓντ , and show that the τ polarization components can be extracted from analyzing the kinematics of the τ visible decay products. In the framework of a general low-energy effective Lagrangian, we then perform a detailed analysis of the polarization components in various aspects and scrutinize possible NP signals. With one upcoming experimental setup, we finally demonstrate promising event rate can be expected for the cascade process and, even in the worst-case scenario—no signals are observed at all—it can still provide a competitive potential for constraining the NP, compared with those from the high- pT dilepton invariant mass tails at high-energy colliders.

摘要：
In this Letter, the first measurement of the inelastic cross section for antitriton-nucleus interactions is reported, covering the momentum range of 0.8 <= < 2.4 GeV/c. The measurement is carried out using data recorded with the ALICE detector in pp and Pb-Pb collisions at a centre-of-mass energy per nucleon of 13 TeV and 5.02 TeV, respectively. The detector material serves as an absorber for antitriton nuclei. The raw yield of (anti)triton nuclei measured with the ALICE apparatus is compared to the results from detailed ALICE simulations based on the GEANT4 toolkit for the propagation of (anti)particles through matter, allowing one to quantify the inelastic interaction probability in the detector material. This analysis complements the measurement of the inelastic cross section of antinuclei up to = 3 carried out by the ALICE Collaboration, and demonstrates the feasibility of the study of the isospin dependence of inelastic interaction cross section with the analysis techniques presented in this Letter.
