【Background and Objective】 Sluice is an important component in hydraulic projects to control water flow, and its performance and diverting capacity are affected by its operating parameters and ambient environment. Understanding how its diversion capacity varies with these factors is important but not trivial. The objective of this paper is to present a new model to estimate the change in diversion capacity of sluice in response to its operating parameters and environmental factors. 【Method】 We took the Weishan sluice in Shandon province as an example. The change in its flowing capacity with factors including the number of its openings, water depth at the back and front of the sluice was analyzed using the radial basis function neural network. Optimization of the network, including the number of its hidden layers, was solved using the genetic algorithm. The model was trained first using measured data, and it was then used to evaluate the performance of the sluice under different operating and environmental conditions. 【Result】 The trained model was accurate, and compared with the measured data, its average error was 1.64%. Results calculated from the model showed that in flooding seasons, the diversion capacity of the sluice meets the design requirement, while during dry seasons its diversion capacity increased with the reduction in the water depth at the back of the sluice. Considering the dredge to be carried out in the downstream sediment conveyance, the calculated flowing capacity meets the design requirements. 【Conclusion】 The GA-RBF model was adaptable and accurate for calculating the diversion capacity of the Weishan sluice.

In order to improve reliability of wind power unit drivetrain,a fault diagnosis model based on quantum genetic algorithm and support vector machine（ SVM） is presented. The model of SVM is conformed,and the penalty parameter and Kernel function coefficient are optimized by quantum genetic algorithm,which coding and renewal of initial population are completed with quantum encoding and rotation gate,the accuracy of optimal solution is improved. Through using the optimized SVM model,with the test and calculation for drivetrain in three types of normal condition,surface wear and missing teeth,the accuracy rate of fault diagnosis can be effectively solved.

Objective To assess knowledge and practices related to snakebite prevention among Chinese residents. Methods By using a multistage random sampling approach augmented by snowball sampling, we surveyed residents from 10 provinces, one municipality and one autonomous region south of the Yangtze River Basin between May 2022 and February 2023. We supplemented the data with a national online survey. We used a [chi square]-test to identify differences in knowledge and behaviour across various demographic characteristics. We conducted multifactor logistic regression analyses to evaluate factors potentially influencing snakebite knowledge and practices. Findings We obtained 55 775 valid survey responses, 16 200 respondents from the face-to-face survey and 39 575 respondents from the online survey. Only 25.7% (14 325) respondents demonstrated adequate knowledge about snakebites whereas 25.6% (14 295) respondents knew basic first-aid practices or preventive behaviours. Age, marital status, educational attainment, occupation, type of residence and frequency of exposure to nature are significant independent variables affecting snakebite knowledge (P-values: Conclusion There is a notable shortfall in knowledge, first aid and preventive behaviours among Chinese residents regarding snakebites. Misguided first aid practices can severely compromise the effectiveness of evidence-based therapeutic interventions. Consequently, improving health education concerning snakes and snakebites in this population is needed.

[phrase omitted] Objectif Evaluer les connaissances et pratiques liees a la prevention des morsures de serpent chez les personnes residant en Chine. Methodes A l'aide d'une approche d'echantillonnage aleatoire a plusieurs degres agrementee d'un echantillonnage en boule de neige, nous avons interroge les habitants de dix provinces, d'une municipalite et d'une region autonome au sud du bassin du fleuve Yangtse entre mai 2022 et fevrier 2023. Nous avons complete ces donnees par une enquete nationale en ligne. Nous avons utilise le test du [chi square] pour reperer les differences entre les connaissances et comportements en lien avec plusieurs caracteristiques demographiques. Enfin, nous avons effectue des analyses multifactorielles de regression logistique afin de determiner les facteurs susceptibles d'influencer les connaissances et pratiques relatives aux morsures de serpent. Resultats Nous avons enregistre 55 775 reponses valides dans le cadre de l'enquete: 16 200 lors d'entretiens en face-a-face et 39 575 en ligne. Seulement 25,7% (14 325) des participants etaient suffisamment informes sur les morsures de serpent, tandis que 25,6% (14 295) des participants connaissaient les premiers soins de base ou les comportements preventifs. Lage, l'etat civil, le niveau d'education, la profession, le type d'habitation et la frequence d'exposition a la nature etaient autant de variables independantes ayant un impact non negligeable sur les connaissances en matiere de morsures de serpent (valeurs-p: < 0,05). En outre, le genre, l'age, l'etat civil, le niveau d'education, la profession et le type d'habitation etaient autant de variables independantes ayant un impact non negligeable sur le comportement en matiere de prevention des morsures de serpent et de premiers soins (valeurs-p: < 0,05). Conclusion Chez les personnes residant en Chine, les connaissances, les pratiques en matiere de premiers soins et les comportements preventifs relatifs aux morsures de serpent ne sont pas suffisants. Accomplir les mauvais gestes lors des premiers soins peut serieusement compromettre l'efficacite des interventions therapeutiques eprouvees. Il est donc imperatif de mieux former cette population aux serpents et a leurs morsures.

Venomous snakebites can cause serious local and systemic symptoms, such as tissue damage, systemic muscular [...]

In order to restrain cement kiln shell’s thermal loss and potential safety hazard, composite design is employed of working layer, thermal-preservation layer and thermal insulation layer. Thermal-preservation layer’s boundary and strain is analyzed and overall thermal conductivity is calculated. The result shows that sinusoidal curve boundary combination between working layer and thermal-preservation layer, slopeshape with angle of 135 degrees between thermal-preservation layer and thermal insulation layer could relieve strain concentration. Composite mullite brick comprehensive thermal conductivity decreases from the working layer 2.74W·m-1·K-1 to 1.50W·m-1·K-1. When applied in cement kiln, temperature of kiln shell is lower 50°C to 70°C than using normal bricks.

The organization of chromatin into self-interacting domains is universal among eukaryotic genomes, though how and why they form varies considerably. Here we report a chromosome-scale reference genome assembly of pepper (Capsicum annuum) and explore its 3D organization through integrating high-resolution Hi-C maps with epigenomic, transcriptomic, and genetic variation data. Chromatin folding domains in pepper are as prominent as TADs in mammals but exhibit unique characteristics. They tend to coincide with heterochromatic regions enriched with retrotransposons and are frequently embedded in loops, which may correlate with transcription factories. Their boundaries are hotspots for chromosome rearrangements but are otherwise depleted for genetic variation. While chromatin conformation broadly affects transcription variance, it does not predict differential gene expression between tissues. Our results suggest that pepper genome organization is explained by a model of heterochromatin-driven folding promoted by transcription factories and that such spatial architecture is under structural and functional constraints.
