Multivariate regression is a widely used technique for large-scale statistical applications. In this paper, we propose a novel method for the multivariate regression model, called multivariate weighted lasso (MWL). We consider the heteroscedasticity in the noise matrix and introduce an adjustable weight to calibrate the fitting residuals of different responses. The proposed method shows an advantage in complex multivariate regressions with heteroscedasticity. To implement the procedure, an efficient algorithm is provided based on the multivariate coordinate descent. We provide theoretical guarantees for the proposed method. Numerical simulations and financial applications are conducted using the proposed and other existing methods. The results indicate that the proposed method performs well in both variable selection and coefficient estimation. [ABSTRACT FROM AUTHOR]

In the treatment of uveal melanoma (UVM), histone deacetylase inhibitors (HDACi) have emerged as a promising epigenetic therapy. However, their clinical efficacy is hindered by the suboptimal pharmacokinetics and the strong self‐rescue of tumor cells. To overcome these limitations, reactive oxygen species (ROS)‐responsive nanoparticles (NPs) are designed that encapsulate HDACi MS‐275 and the glutamine metabolism inhibitor V‐9302. Upon reaching the tumor microenvironment, these NPs can disintegrate, thereby releasing MS‐275 to increase the level of ROS and V‐9302 to reduce the production of glutathione (GSH) related to self‐rescue. These synergistic effects lead to a lethal ROS storm and induce cell pyroptosis. When combined with programmed cell death protein 1 monoclonal antibodies (α‐PD‐1), these NPs facilitate immune cell infiltration, improving anti‐tumor immunity, converting "immune‐cold" tumors into "immune‐hot" tumors, and enhancing immune memory in mice. The findings present a nano‐delivery strategy for the co‐delivery of epigenetic therapeutics and metabolic inhibitors, which induces pyroptosis in tumors cells and improves the effectiveness of chemotherapy and immunotherapy.

Despite suicide in younger population having become a severe public health issue, information on the prevalence of suicidality among Chinese children and adolescents is still limited. This study aims to estimate the prevalence of suicidal ideation, suicide plans, and suicide attempts in Chinese children and adolescents aged under 18 years. A meta-analysis was conducted based on English and Chinese publications from January 1, 2010 to December 31, 2020 using random-effects models. Based on 132 eligible studies with a combined total of 1,103,309 Chinese children and adolescents below 18 years old, the pooled prevalence of the overall suicidal ideation, suicide plans, and suicide attempts were 15.4% (95% CI [14.3, 16.6]), 6.4% (95% CI [5.5, 7.4]) and 3.5% (95% CI [3.1, 4.1]), respectively. The subgroup analyses showed that there were significant variations of prevalence of suicidal risks across genders, school stages, and geographical areas in mainland China. It was the first systematic review and meta-analysis to show suicidality among younger population aged below 18 years is prevalent in mainland China. This study suggests that gender-age-region-specific prevention and intervention programs should be urgently needed to reduce suicidal risks among Chinese children and adolescents.

A novel and comprehensive resource utilization technology involving the production of biomass fuel rods and the creation of water-retaining and loose media derived from food waste has been developed as a result of the increased focus on the efficient utilization of resources derived from food waste in recent years. This technical procedure produced a novel wastewater stream that was identified as food waste squeezing liquid. The study was primarily concerned with examining the effects of temperature on the anaerobic fermentation method used to produce methane from food waste squeezing liquid and with examining changes in the microbial population during the fermentation process. After 53 days of anaerobic fermentation at the ideal temperature 47 °C, 17 220 mL of gas were produced overall, with peak methane production accounting for 70%~75% of the total gas output. This peak methane production was 2.5 times higher than that observed at 37 °C. It's interesting to note that after the fifth day of fermentation, no methane generation was seen at temperatures of 27 °C, 57 °C, and 67 °C. After performing high-throughput sequencing on the 16S rDNA, the relative abundance of unclassified_d_Bacteria decreased significantly from 83.92% to only 24.16% during fermentation under low oxygen conditions. Under strict anaerobic conditions, the proportion of Clostridium increased dramatically from a mere percentage of just 0.93% to as high as 44.75%, but it eventually dropped down to 5.40% after concluding the fermentation experiment. Subsequently, the relative abundance of unclassified_d_Bacteria rebounded and rose sharply from 24.16% to 68.12%. The findings of this study offer valuable insights into the optimization of anaerobic fermentation temperature selection and the choice of bacterial strains applicable in the practical engineering implementation of food waste squeezing liquid.

Currently, the predominant thermal insulation materials in the construction industry are primarily derived from inorganic sources. While these materials demonstrate commendable thermal insulation capabilities, their widespread use raises significant environmental concerns. The utilization of wood fiber materials presents a promising solution to mitigate these drawbacks. This study focuses on the fabrication of biodegradable fiber insulation board (BFIB) using camphor branches. The manufacturing process avoids the use of chemical additives, employing a physical method that utilizes hot pressing and relies on the formation of intermolecular hydrogen and hydroxide bonds between the fibers. The study evaluates the influence of applied pressure on the properties of BFIB. SEM images reveal that, with an increase in applied pressure, the fibers exhibit a more regular pattern, subsequently enhancing the mechanical properties, hygric behavior, and fire resistance properties of BFIB. As an environmentally friendly and renewable material, BFIB holds the potential to substitute conventional insulation materials. It is particularly intriguing for energy-saving purposes when applied as building insulation for walls or ceilings. [ABSTRACT FROM AUTHOR]
