Back.round: In this study, the Universal Mental Health Literacy Scale for Adolescents (UMHL-A) was revised and tested for its reliability and validity in Chinese middle school students, thus establishing a useful tool for assessing the mental health of individuals in this occupation. Methods: Our sample comprised 1208 junior high school students (58.85% male), aged between 11 and 15 years old. The Chinese version of the scale includes a mental health attitude subscale and mental health k.owledge subscale, including attitudes towards seek.ng help, attitudes related to stigma, general mental health k.owledge, and k.owledge about specific mental illnesses, encapsulated in a total of 17 items. A series of psychometric analyses such as exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and internal consistency reliability estimation were carried out in this study. Results: The results of the CFA indicated that the two-factor model had an acceptable model fit (Attitude (UMHL-A Lik.rt): χ2/df = 4.107; RMSEA = 0.072; SRMR = 0.045; TLI = 0.932; CFI = 0.954; k.owledge (UMHL-A T/F): χ2/df = 3.647; RMSEA = 0.066; SRMR = 0.044; TLI = 0.923; CFI = 0.945). The Cronbach’s alpha coefficient of subscales of the Chinese version UMHL-A were 0.80 and 0.78, respectively. Conclusion: In general, the Chinese version of the Universal Mental Health Literacy Scale for adolescents has good reliability and validity and can be used as a tool to measure the mental health literacy of Chinese adolescents. © 2024 The Authors.

This paper proposes a critical clearing time (CCT) estimation method by the domain of attraction (DA) of a state-reduction model of power systems using sum of sq.ares (SOS) programming. By exploiting the property of the Jacobian matrix and the structure of the boundary of the DA, it is found the DA of the state-reduction model and that of the full model of a power system are topological isomorphism. There are one-to-one correspondence relationships between the number of eq.ilibrium points, the type of eq.ilibrium points, and solutions of the two system models. Based on these findings, an expanding interior algorithm is proposed with SOS programming to estimate the DA of the state-reduction model. State trajectories of the full model can be transformed to those of the state-reduction model by orthogonal or eq.iradius projection. In this way, CCT of a grid fault is estimated with the DA of the state-reduction model. The calculational burden of SOS programming in the DA estimation using the state-reduction model is rather small compared with using the full model. Simulation results show the proposed expanding interior algorithm is able to provide a tight estimation of DA of power systems with higher accuracy and lower time costs.

The γ-ray emission from the W51 complex is widely ack.owledged to be attributed to the interaction between the cosmic rays (CRs) accelerated by the shock.of supernova remnant (SNR) W51C and the dense molecular clouds in the adjacent star-forming region, W51B. However, the maximum acceleration capability of W51C for CRs remains elusive. Based on observations conducted with the Large High Altitude Air Shower Observatory (LHAASO), we report a significant detection of γ rays emanating from the W51 complex, with energies from 2 to 200 TeV. The LHAASO measurements, for the first time, extend the γ-ray emission from the W51 complex beyond 100 TeV and reveal a significant spectrum bending at tens of TeV. By combining the "π0-decay bump" featured data from Fermi-LAT, the broadband γ-ray spectrum of the W51 region can be well-characterized by a simple pp-collision model. The observed spectral bending feature suggests an exponential cutoff at ∼400 TeV or a power-law break.at ∼200 TeV in the CR proton spectrum, most lik.ly providing the first evidence of SNRs serving as CR accelerators approaching the PeV regime. Additionally, two young star clusters within W51B could also be theoretically viable to produce the most energetic γ rays observed by LHAASO. Our findings strongly support the presence of extreme CR accelerators within the W51 complex and provide new insights into the origin of Galactic CRs. © 2024 Science China Press

Objective This study aimed to estimate the therapeutic effects of preformed metal crown (PMC) and prefabricated zirconia crowns (ZC) on decayed primary morals in children, as well as to analyze the possible influencing factors. Methods A retrospective cohort study was performed on the data of 192 patients (aged 3 to 8) in the Stomatological Department of Shenzhen Children’s Hospital from October 2021 to December 2021. The decayed mandibular first molars were selected and restored by vital-pulp therapy followed by PMC and ZC, including 96 cases (96 caries) in the PMC group and 96 cases (96 caries) in the ZC group. Oral clinical examination was performed at 3 months, 1 year, and 2 years after treatment, overwiewing the clinical therapeutic effects and periodontal status of PMC and ZC groups, as well as recording the crown integrity, gingival index (GI), probing bleeding index (BI), plaq.e index (PLI) and various prosthetic indices. Results No significance differences existed in the periodontal status of PMC and ZC groups at 3 months, 1 year, and 2 years after treatment (P>0.05). However, the GI, BI, and PLI in the PMC group were higher than those in the ZC group at 3 months, 1 year, and 2 years after treatment, and the difference was dramatically significant (P0.05), as well as in the GI, BI, and PLI, between the two groups (P>0.05). No significant differences existed in various prosthetic indices between genders after PMC restoration (P>0.05). The scores of girls in various prosthetic indices after ZC restoration were higher than those of boys (P0.05). Conclusion PMC and ZC can be applied to restore deciduous molar caries. The periodontal status of deciduous teeth in ZC group was superior to that in the PMC group. The
