The weighted sum of powers in mean for estimating a change point in linear processes with random coefficients.

Let be a sequence of linear process based on dependent random variables with random coefficients, which has a mean shift at an unknown location. The weighted sum of powers in mean (WSPM, for short) estimator of the change point is proposed. The weak consistency, the rate of weak consistency and strong consistency for the WSPM estimator are established under some mild conditions.

Application of machine learning in acute upper gastrointestinal bleeding: bibliometric analysis.

Cooperation resonance based on link strategy reinforcement learning and conformity.

We propose a game model that integrates reinforcement learning (RL) with link strategies and conformity behavior to investigate the emergence and maintenance of cooperation. The model operates on a lattice network with periodic boundaries and includes two types of nodes: RL nodes with link strategies and conformist nodes. Simulation results reveal a range of critical mass.

Global burden of low back pain and its attributable risk factors from 1990 to 2021: a comprehensive analysis from the global burden of disease study 2021.

Materials And Methods: LBP-related data were obtained from the Global Health Data Exchange (GHDx) query tool. All estimates and their 95% uncertainty intervals (UIs) were generated using DisMod-MR 2.

Partial thermal atomization of residual Ni NPs in single-walled carbon nanotubes for efficient CO electroreduction.

CO electroreduction (CORR) is an important solution for converting inert CO into high value-added fuels and chemicals under mild conditions. The decisive factor lies in the rational design and preparation of cost-effective and high-performance electrocatalysts. Herein, we first prepare a novel f-SWNTs-650 catalyst a facile partial thermal atomization strategy, where the residual Ni particles in single-walled carbon nanotubes (SWNTs) are partially converted into atomically dispersed NiN species.

Environmental taxes promote the synergy between pollution and carbon reduction: Provincial evidence from China.

Since its implementation in 2018, China's environmental tax has become a crucial mechanism in the nation's strategy for reducing environmental pollution. However, its synergistic effect between pollution and carbon reduction has not been adequately focused on and evaluated. This study employs the difference-in-differences (DID) model to analyze the impact of the environmental tax policy on the emissions of pollutant and CO as well as the synergistic effect between them.

Global, regional and country-specific burden of patella, tibia or fibula, or ankle fractures and its prediction to 2035: findings from global burden of disease study 2019.

Background: Bone fractures are a global public health issue and a major source of significant illness and financial hardship. However, to date, there is limited research on patella, tibia or fibula, or ankle fractures (FPTFA) disease burden.

Methods: Using the framework of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, we conducted temporal trends of disease burden, effects of sex and socio-demographic index (SDI) on age standardized prevalence rate (ASPR) and age-period-cohort model.

Does import trade liberalization worsen residents' health? Evidence from China.

Health is important to human capital and national sustainable development. Based on the latest Chinese Family Panel Studies (CFPS), this paper uses the IVprobit model to test the impact of import trade liberalization on residents' health from the micro-individual perspective and further explores its mechanism. The results indicate that import trade liberalization brings hidden health costs, and that the negative effects on the health of people in eastern China or rural areas, people with a low education background, people under 60 years of age, and women are more significant.

Study on Optimal Nitrogen Application for Different Oat Varieties in Dryland Regions of the Loess Plateau.

The present study endeavored to tackle the challenges posed by limited diversity in oat varieties and suboptimal nitrogen fertilizer utilization in the arid landscapes of the Loess Plateau. We selected three oat varieties, including early-maturing oats (E), medium-maturing oats (M), and late-maturing oats (L). In 2022, four nitrogen applications were set up as CK (0 kg N ha), N1 (60 kg N ha), N2 (90 kg N ha), and N3 (120 kg N ha).

Chitosan-based emulsive liquid-liquid microextraction for the determination of strobilurin fungicides in water samples.

Strobilurin fungicides are widely used pesticides globally; however, their residues pose a risk to environmental safety and human health. This study aimed to develop a rapid and green method for detecting strobilurin fungicide residues. Chitosan and magnetic deep eutectic solvent-based emulsive liquid-liquid microextraction method combined with high-performance liquid chromatography was developed to determine strobilurin fungicides in water samples.

Exploring the patterns of China's carbon neutrality policies.

To achieve the ambitious carbon neutrality goal by 2060, the Chinese government has implemented a series of carbon neutrality policies. These policy documents are pivotal in facilitating the examination of policy substance, the scrutiny of policy evolution, and the dissection of the policy instruments involved. This study develops an analytical framework for assessing carbon neutrality through policy documents, applying text mining and network analysis to probe the intricacies of policy topics, interagency collaboration, and diffusion dynamics.

Global, regional, and national total burden related to hepatitis B in children and adolescents from 1990 to 2021.

Background: Hepatitis B remains a significant global health concern with widespread communicability. Nevertheless, data on its burden and trends in children and adolescents were limited. We aim to evaluate the global, regional, and national trends of total burden related to hepatitis B in children and adolescents aged 0-19 years from 1990 to 2021.

Comprehensive analysis of the global impact and distribution of tick paralysis, a deadly neurological yet fully reversible condition.

SUMMARYTick paralysis is a potentially fatal condition caused by neurotoxins secreted by the salivary glands of certain ticks. Documented cases have been reported worldwide, predominantly in the United States, Canada, and Australia, with additional reports from Europe and Africa. This condition also affects animals, leading to significant economic losses and adverse impacts on animal health and welfare.

Examining the relationship between the built environment and carbon emissions from operating vehicles: enlightenment from nonlinear models.

Carbon emissions from urban transportation significantly contribute to overall transportation emissions and are a major cause of the continuous rise in global temperatures. Understanding the spatial distribution and influencing factors of carbon emissions from operating vehicles can aid in formulating targeted policies and promoting emission reduction. To analyze the factors influencing urban traffic carbon emissions, we calculated emissions using trajectory data from operating vehicles in Shenzhen.
