    Abstract Polylactide/poly(butylene adipate-co-terephthalate) (PLA/PBAT) blends were compatibilized using dicumyl peroxide (DCP) and poly(ethylene glycol) 600 diacrylate (PEG600DA) through a one-step melt-blending process. The compatibility and performance of these blends were subsequently characterized. The results showed that grafts formed "in situ" effectively improved the compatibility and interfacial adhesion between PLA and PBAT phases. Melt viscosity and elasticity of both the PLA/PBAT/DCP and PLA/PBAT/DCP/PEG600DA blends evinced significant increases. Compared to PLA alone, both cold and melt crystallization abilities of the PLA/PBAT/DCP/PEG600DA blends were enhanced, with crystallinities increasing by 5 % - 10 %. Furthermore, the thermal stability, as well as hydrophobicity and oleophobicity of the compatibilized blends improved. In comparison with PLA, the elongation at break and notched impact strength for the PLA/PBAT/DCP/PEG600DA (60/40/0.1/4) blend achieved increases of 290 % and 44.23 kJ/m

    Abstract Disturbances in immunoregulation may lead to both cancer and autoimmune diseases. Many therapeutic drugs for autoimmune diseases also display anti-tumor efficacy. The Janus kinase/signal transducer and activator of transcription signaling pathways are involved in the secretion of more than 50 distinct cytokines, which have critical roles in inducing autoimmune diseases and tumorigenesis. Thus, Janus kinases have become classical immunotherapeutic targets for immune disease. More than 70 Janus kinase inhibitors have been approved as immunomodulatory drugs for clinical use, of which 12 are used in the treatment of autoimmune diseases. This systematic review aims to elucidate the anti-tumor role of clinically approved Janus kinase inhibitors that were primarily designed for the treatment of autoimmune diseases and their potential for clinical translation as cancer treatments.

    Abstract The present study examined the cross-modal cueing effect of musical rhythmic beats on non-native speech rhythm production. Two groups of Chinese learners of French were cued respectively with rhythmic beats that either matched (matching group) or mismatched (mismatching group) the rhythm patterns of the target French sentences. The participants were asked to produce the target sentences after cueing and their speech production was compared with their baseline condition in which no cueing was used. The results showed that the matching group produced the target French rhythm significantly better after cueing with musical rhythmic beats that matched the French rhythm, in contrast to the mismatching group where no significant improvement was found. Individual differences in auditory short-term memory and rhythmic skills were not related to improvement in producing French rhythm after cueing. The results suggest that musical rhythmic cueing can be used to improve non-native speech rhythm production, further indicating a close link between speech and music in the temporal domain.

    Abstract This paper propose a new frame work for finding global minima which we call optimization by cut. In each iteration, it takes some samples from the feasible region and evaluates the objective function at these points. Based on the observations it cuts off from the feasible region a subregion that is unlikely to contain a global minimum. The procedure is then repeated with the feasible region replaced by the remaining region until the remaining region is ``small'' enough. If a global minimum is kept in the remaining region of each iteration, then it can be located with an arbitrary precision. The frame work is surprisingly efficient in view of its simple form and can be applied to black-box functions since neither special structure nor derivative information is required. The performance of the proposed frame work is evaluated on some benchmark functions and the results show that it can find a global minimum rather quickly.

    Abstract In the present paper, a novel vector field decomposition based approach for constructing Lyapunov functions is proposed. For a given dynamical system, if the defining vector field admits a decomposition into two mutually orthogonal vector fields, one of which is curl-free and the other is divergence-free, then the potential function of the former can serve as a Lyapunov function candidate, since its positive definiteness will reflect the stability of the system. Moreover, under some additional conditions, its sublevel sets will give the exact attraction domain of the system. A sufficient condition for the existence of the proposed vector field decomposition is first obtained for $2$-dimensional systems by solving a partial differential equation and then generalized to $n$-dimensional systems. Furthermore, the proposed vector field decomposition always exists for linear systems and can be obtained by solving a specific algebraic Riccati equation.

    Abstract Objective: This study aimed to determine the postoperative effects of music therapy on negative emotions, pain, and inflammatory and physiological parameters in patients undergoing colonoscopic polypectomy.
    Methods: Patients who underwent colonoscopic polypectomy in Funan County People's Hospital between March 2020 and June 2023 were selected as the research subjects. Patients were divided into exposure (underwent music therapy) and control (did not undergo music therapy) groups. Baseline characteristics, Self-rating Anxiety Scale (SAS) and Visual Analog Scale (VAS) scores, physiological parameters [systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR)], and inflammatory marker levels [neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and erythrocyte sedimentation rate (ESR)] of patients before and after exposure to music were determined. The propensity score matching (PSM) method (1:1) was used to balance the baseline characteristics of the two groups.
    Results: After PSM, the exposure group comprised 50 cases and the control group comprised 50 cases. The baseline characteristics were not significantly different between the two groups (P > 0.05). The postoperative SAS score of the exposure group was significantly lower than that of the control group (P < 0.05). Meanwhile, the postoperative VAS score of the exposure group was nonsignificantly lower than that of the control group (P > 0.05). Furthermore, the postoperative SBP, DBP, and HR levels of the exposure group were significantly lower than that of the control group (P < 0.05). The postoperative levels of NLR, PLR, and ESR were not significantly different between the exposure and control groups (P > 0.05).
    Conclusion: Music therapy exerts beneficial effects on the postoperative psychological and physiological parameters of patients undergoing colonoscopic polypectomy.

    Abstract Suicide is a serious public health problem for adolescents. Based on the framework of ideation-to-action, it is important to examine the factors associated with the translation from suicide ideation to suicide attempt. The present study aimed to investigate the risk factors of suicide attempts among adolescents with suicide ideation in low-income and middle-income countries (LMICs). We analyzed data of students aged 12-18 years who participated in the 2009-2013 Global School-based Health Surveys (GSHS) in 39 LMICs. The Chi-square test was used to compare the prevalence of suicide attempts among participants with suicide ideation, the multilevel logistic regression model was used to identify significant factors associated with suicide attempts among suicide ideators. Among 22,655 adolescents with suicide ideation, 55.1% of them reported having made a suicide attempt in the past year. Loneliness, anxiety, alcohol use, and drug use were risk factors for suicide attempts among suicide ideators. Strategies should be implemented to reduce the likelihood of adolescents acting on their suicidal thoughts, such as community psychological crisis line, school-based mental health and skills training programs, and family support for adolescents with psychological problems.
