Organic phosphorescence or thermally activated delayed fluorescence (TADF) scintillators, while effective in utilizing triplet excitons, are sensitive to temperature changes, which can impact radioluminescence performance. In this study, we have developed a type of temperature-adaptive organic scintillator with phosphorescence and TADF dual emission. These scintillators can automatically switch modes with temperature changes, enabling efficient radioluminescence from 77 to 400 K.

However, the presence of oxidative stress during the production and application process can cause bacterial damage or even death, significantly compromising the functionality of probiotics. Despite its potential for broader application scenarios that could provide a more comprehensive understanding of bacteria's internal adaptation strategies, there is a lack of research investigating oxidative stress from the perspective of culture methods.

While skeletal muscle is the primary insulin-sensitive tissue in mammals, the effects of insulin on chicken skeletal muscle remain unclear. In this study, the insulin-responsive metabolites were identified in broiler's pectoralis muscle (after 16 h of fasting) using widely targeted metabolomics.

Based on the data of land use in 1990, 2000, 2010, and 2020, the land use transfer matrix model, dynamic attitude and state degree model, InVEST model, and geographically weighted regression model were adopted. The research results were as follows: ① From 1990 to 2020, the area of unused land in Hexi Corridor changed the most, with a decrease of 3 021 km and the cultivated land, construction land, and water area increased by 2 343.

The digging processes of the buckets were simulated using the discrete element method. The results show that, compared with the prototype buckets, all seven types of bionic buckets have significant drag reduction effects at the same digging depth, and the drag reduction effects increase with the decrease of digging speed.

Light detection and ranging (LiDAR) systems based on indirect time-of-flight (iToF) sensors have garnered considerable interest due to their all-solid-state design, high resolution, high reliability, and cost-effective nature. However, the challenge of extending the operational range of iToF LiDAR systems without compromising the range precision is a significant barrier to their broader application. This paper introduces what we believe to be a novel method to overcome these hurdles, which involves pre-setting the delay between the light pulse emission and the sensor's transfer gates to extend the operational range and utilizing spatial overlap fusion techniques to enhance the range precision.

To test the hypothesis and identify potential contributing factors, we designed an ecological study based on the GDB-2019 data and extracted age-standardized incidence rates (ASIRs) of IHD and stroke, and summary exposure values (SEVs) of 87 attributable factors. A declining trend was observed for ASIRs of stroke (globally from 181.

Objective: This study aimed to investigate the association between biological aging and AF.
Methods: A total of 371,882 participants without AF at baseline from the UK Biobank were included.
Dynamic control of terahertz metamaterials using thin organic perovskite active layers has been extensively researched. However, the preparation of organic perovskite devices requires strict environmental conditions, and the devices are prone to hydrolysis in air, which reduces performance. Herein, we report an optical terahertz metamaterial switch controlled via hybridization with high-stability CsPbBr microcrystals prepared through precipitation from a water-dimethylformamide (DMF) mixed-solution.

In response to the presence of bandwidth constraints and mixed cyber-attacks in USV communication networks, this paper proposes an improved set-membership state estimation algorithm based on BCS. This algorithm partially addresses the problem of degraded performance in USV steering motion state estimation caused by mixed cyber-attacks and bandwidth constraints.

Milk production is an essential economic trait in cattle, and understanding the genetic regulation of this trait can enhance breeding strategies. The discoidin domain receptor 1 () gene has been identified as a key candidate gene that influences milk production, and ETS homologous factor (EHF) is recognized as a critical transcription factor that regulates expression. Codon usage bias, which affects gene expression and protein function, has not been fully explored in cattle.
