摘要：
Using (10087 +/- 44) x 10(6) J/psi events collected with the BESIII detector at the BEPCII e(+)e(-) storage ring at the center-of-mass energy of root s = 3.097 GeV, we present a search for the rare semi-muonic charmonium decay J/psi -> D-mu(+)nu(mu) + c.c.. Since no significant signal is observed, we set an upper limit of the branching fraction to be B (J/psi -> D-mu(+)nu(mu) + c.c.) < 5.6 x 10(-7) at 90% confidence level. This is the first search for the weak decay of charmonium with a muon in the final state.

摘要：
Strangeon stars, which are proposed to describe the nature of pulsar-like compact stars, have passed various observational tests. The maximum mass of a non-rotating strangeon star could be high, which implies that the remnants of binary strangeon star mergers could even be long-lived massive strangeon stars. We study rigidly rotating strangeon stars in the slowly rotating approximation, using the Lennard-Jones model for the equation of state. Rotation can significantly increase the maximum mass of strangeon stars with unchanged baryon numbers, enlarging the mass-range of long-lived strangeon stars. During spin-down after merger, the decrease of radius of the remnant will lead to the release of gravitational energy. Taking into account the efficiency of converting the gravitational energy luminosity to the observed X-ray luminosity, we find that the gravitational energy could provide an alternative energy source for the plateau emission of X-ray afterglow. The fitting results of X-ray plateau emission of some short gamma-ray bursts suggest that the magnetic dipole field strength of the remnants can be much smaller than that of expected when the plateau emission is powered only by spin-down luminosity of magnetars.
摘要：
Particulate matter, represented by soot particles, poses a significant global environmental threat, necessitating efficient control technology. Here, we innovatively designed and elaborately fabricated ordered hierarchical macroporous catalysts of Ce(0.8)Zr(0.2)O(2) (OM CZO) integrated on a catalyzed diesel particulate filter (CDPF) using the self-assembly method. An oxygen-vacancy-enriched ordered macroporous Ce(0.8)Zr(0.2)O(2) catalyst (V(O)-OM CZO) integrated CDPF was synthesized by subsequent NaBH(4) reduction. The V(O)-OM CZO integrated CDPF exhibited a markedly enhanced soot oxidation activity compared to OM CZO and powder CZO coated CDPFs (T(50): 430 vs 490 and 545 °C, respectively). The well-defined OM structure of the V(O)-OM CZO catalysts effectively improves the contact efficiency between soot and the catalysts. Meanwhile, oxygen vacancies trigger the formation of a large amount of highly reactive peroxide species (O(2)(2-)) from molecular oxygen (O(2)) through electron abstraction from the three adjacent Ce(3+) (3Ce(3+) + Vö + O(2) → 3Ce(4+) + O(2)(2-)), contributing to the efficient soot oxidation. This work demonstrates the fabrication of the ordered macroporous CZO integrated CDPF and reveals the importance of structure and surface engineering in soot oxidation, which sheds light on the design of highly efficient PM capture and removal devices.

摘要：
Although being applied as photosensitizers for photodynamic therapy, covalent organic frameworks (COFs) fail the precise fluorescence imaging in vivo and phototherapy in deep-tissue, due to short excitation/emission wavelengths. Herein, this work proposes the first example of NIR-II emissive and benzobisthiadiazole-based COF-980. Comparing to its ligands, the structure of COF-980 can more efficiently reducing the energy gap (Delta ES1-T1) between the excited state and the triplet state to enhance photodynamic therapy efficiency. Importantly, COF-980 demonstrates high photostability, good anti-diffusion property, superior reactive oxygen species (ROS) generation efficiency, promising imaging ability, and ROS production in deep tissue (approximate to 8 mm). Surprisingly, COF-980 combined with laser irradiation could trigger larger amount of intracellular ROS to high efficiently induce cancer cell death. Notably, COF-980 NPs precisely enable PDT guided by NIR-II fluorescence imaging that effectively inhibit the 4T1 tumor growth with negligible adverse effects. This study provides a universal approach to developing long-wavelength emissive COFs and exploits its applications for biomedicine. This pioneering NIR-II emissive COF-980 based on the benzobisthiadiazole scaffold has a series of better performance, demonstrating high photostability, good anti-diffusion property, superior reactive oxygen species generation efficiency, promising imaging ability, and ROS production in deep tissue (approximate to 8 mm), which are highly promising for bioimaging, photodynamic therapy, and other related biomedical fields. image
摘要：
In this study, we compute the electromagnetic and hadronic decay widths of the S-wave fully heavy tetraquark T4Q (Q = c or b) at lowest order in alpha s and v, in the framework of nonrelativistic QCD. The short-distance coefficients are determined through the standard procedure of matching. The nonperturbative long-distance matrix elements are related to the phenomenological four-body Schrodinger wave functions at the origin, whose values are taken from literature. The branching fractions are predicted to be around 10-3 and 10-6 for the T4c hadronic decay and electromagnetic decay, respectively. Combining our results with the T4c production cross sections at the LHC, we also predict the event numbers for various decay channels. With integrated luminosity L = 100 fb-1, it is expected that the event numbers can reach 103-104 for T4c -> gamma gamma, and 105-106 for T4c -> LH, at the LHC. The detecting prospect is promising. In addition, the decay widths of T4b are estimated based on simple dimensional analysis as well as velocity scaling rule.

摘要：
In the swiftly evolving landscape of Internet of Things (IoT) technology, the demand for adaptive non-contact sensing has seen a considerable surge. Traditional human perception technologies, such as vision-based approaches, often grapple with problems including lack of sensor versatility and sub-optimal accuracy. To address these issues, this paper introduces a novel, non-contact method for human presence perception, relying on WiFi. This innovative approach involves a sequential process, beginning with the pre-processing of collected Channel State Information (CSI), followed by feature extraction, and finally, classification. By establishing signal models that correspond to varying states, this method enables the accurate perception and recognition of human presence. Remarkably, this technique exhibits a high level of precision, with sensing accuracy reaching up to 99%\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\%$$\end{document}. The potential applications of this approach are extensive, proving to be particularly beneficial in contexts such as smart homes and healthcare, amongst various other everyday scenarios. This underscores the significant role this novel method could play in enhancing the sophistication and effectiveness of human presence detection and recognition systems in the IoT era.
摘要：
Abstract Background Leaderboards are a highly popular gamification component used in student learning to enhance motivation, attentional engagement, and learning performance. However, few studies have examined the effects of individual leaderboard elements on English vocabulary learning through video lectures. Objectives The present study aimed to examine how different leaderboard elements (i.e., points and rank) may affect students' English vocabulary learning through video lectures. Methods A total of 34 students were assigned to groups using different leaderboard elements in a counterbalanced order. Participants' motivation, eye movements, and learning performance were measured and analysed. Results and Conclusions Students' leaderboard rank was shown to increase their motivation regardless of whether other elements were present. Eye movement tracking revealed that the presence of the leaderboard increased students' saccades between the questions and the options, and lengthened their dwell time on the learning materials while reducing their dwell time on the non‐learning‐related screen areas. Presenting students' rank alone also improved their learning performance. Implications Our findings strongly support the use of video lectures for English vocabulary learning, with the following recommendations: (1) Instructors should present students' rank on the leaderboard to enhance students' motivation and engagement; (2) Instructors should present only the students' rank on the leaderboard to also enhance students' learning performance.
