Multi-scale urban ecosystem service changes and their impact mechanisms on human well-being.

With increasing urbanization pressures, there is an urgent need to improve the urban residents' well-being and achieve the sustainable development goals (SDGs). Ecosystem services (ESs) are vital for human well-being (HW) and survival, providing essential benefits like clean water while supporting the SDGs. However, understanding the impact mechanism of urban ESs on the HW under the framework of the SGDs in a changing world remains challenging.

A fluorescent sensor based on pentafluoropropanoic acid-functionalized UiO-66-NH for enhanced selectivity and sensitivity of dicloran detection.

What factors influence secondary students' active participation in mathematics classrooms: A theory of planned behavior perspective.

Active Student Participation (ASP) is important for academic success and increased motivation in educational processes. This is because the mathematics outcomes can be significantly improved when students engage actively in the learning process. However, limited studies have been conducted on the factors influencing ASP in mathematics classrooms and strategies for enhancement despite the benefits.

Brassica rapa receptor-like cytoplasmic kinase BrRLCK1 negatively regulates freezing tolerance in transgenic Arabidopsis via the CBF pathway.

Some winter rapeseed (Brassica rapa) varieties can endure extremely low temperatures (-20°C to -32°C). However, because of a lack of mutant resources, the molecular mechanisms underlying cold tolerance in B. rapa remain unclear.

Multi-Band Scattering Characteristics of Miniature Masson Pine Canopy Based on Microwave Anechoic Chamber Measurement.

Using microwave remote sensing to invert forest parameters requires clear canopy scattering characteristics, which can be intuitively investigated through scattering measurements. However, there are very few ground-based measurements on forest branches, needles, and canopies. In this study, a quantitative analysis of the canopy branches, needles, and ground contribution of Masson pine scenes in C-, X-, and Ku-bands was conducted based on a microwave anechoic chamber measurement platform.

Leaf Phosphorus Fractions Are Coordinated with Leaf Functional Traits in Four Juvenile Tree Species from the Chinese Subtropics.

Phosphorus (P) is essential for cellular processes, and P fractions within leaf tissues reflect distinct biochemical functions. However, the relationship among foliar P allocation, leaf functional traits, and soil properties in subtropical China remains poorly understood. Here, we investigated four tree species to examine the relationships among foliar P fractions (orthophosphate P, metabolic P, nucleic acid P, lipid P, and residual P), key leaf functional traits (LMA, A, and leaf [N], and P concentrations), and soil properties.

Differential diversity and structure of autotrophs in agricultural soils of Qinghai Province.

Unlabelled: The biodiversity of CO-assimilating bacterial communities is pivotal for carbon sequestration in agricultural systems. Changes in the diversity, structure, and activity of the soil chemolithoautotrophic bacteria were examined in four agricultural areas, Dulan (DL), Gonghe (GH), Huzhu (HZ), and Datong (DT) counties in Qinghai Province, where wheat, oilseed rape, and barley were planted. This process was performed using Illumina amplicon sequencing of the ribulose-1,5-bisphosphatecarboxylase/oxygenase (RubisCO) gene ( Form I) and activity data.

Pharmacological Mechanisms of Bile Acids Targeting the Farnesoid X Receptor.

Bile acids (BAs), a category of amphiphilic metabolites synthesized by liver cells and released into the intestine via the bile duct, serve a vital role in the emulsification of ingested fats during the digestive process. Beyond their conventional emulsifying function, BAs, with their diverse structures, also act as significant hormones within the body. They are pivotal in facilitating nutrient absorption by interacting with the farnesoid X receptor (FXR), and they serve as key regulators of lipid and glucose metabolism, as well as immune system balance.

The Response Mechanism of the cbbM Carbon Sequestration Microbial Community in the Alpine Wetlands of Qinghai Lake to Changes in Precipitation.

[Characteristics of soil carbon, nitrogen, and water of plantation along different vegetation restoration years in alpine sandy region].

As the most effective way to remedy and reconstruct the degraded ecosystems, vegetation restoration could affect soil carbon and nitrogen cycles and water balance. We examined the responses of carbon, nitrogen, and water in 0-200 cm soil layer to vegetation restoration years by analyzing their distribution characteristics across a restoration chronosequence of plantation (5, 10, 15, 20, and 25 years) in alpine sandy region of the Qinghai-Tibetan Plateau. The results showed that the content and storage of soil organic carbon (SOC) and soil total nitrogen (STN) increased significantly, while that of soil inorganic carbon (SIC) decreased significantly with restoration years.

Design of an Ultra-Highly Stable Lithium-Sulfur Battery by Regulating the Redox Activity of Electrocatalyst and the Growth of Lithium Dendrite through Localized Electric Field.

Polysulfide shuttling and dendrite growth are two primary challenges that significantly limit the practical applications of lithium-sulfur batteries (LSBs). Herein, a three-in-one strategy for a separator based on a localized electrostatic field is demonstrated to simultaneously achieve shuttle inhibition of polysulfides, catalytic activation of the Li-S reaction, and dendrite-free plating of lithium ions. Specifically, an interlayer of polyacrylonitrile nanofiber (PNF) incorporating poled BaTiO (PBTO) particles and coating with a layer of MoS (PBTO@PNF-MoS) is developed on the PP separator.

Responses of Soil Respiration and Ecological Environmental Factors to Warming and Thermokarst in River Source Wetlands of the Qinghai Lake Basin.

Global climate warming has led to the deepening of the active layer of permafrost on the Tibetan Plateau, further triggering thermal subsidence phenomena, which have profound effects on the carbon cycle of regional ecosystems. This study conducted warming (W) and thermal subsidence (RR) control experiments using an Open-Top Chamber (OTC) device in the river source wetlands of the Qinghai Lake basin. The aim was to assess the impacts of warming and thermal subsidence on soil temperature, volumetric water content, biomass, microbial diversity, and soil respiration (both autotrophic and heterotrophic respiration).

Information Propagation in Hypergraph-Based Social Networks.

Social networks, functioning as core platforms for modern information dissemination, manifest distinctive user clustering behaviors and state transition mechanisms, thereby presenting new challenges to traditional information propagation models.
