Electroly.is tanks are used to smelt metals based on electrochemical principles, and the short-circuiting of the pole plates in the tanks in the production process will lead to high temperatures, thus affecting normal production. Aiming at the problems of time-consuming and poor accuracy.of existing infrared methods for high-temperature detection of dense pole plates in electroly.is tanks, an infrared dense pole plate anomalous target detection network y.LOv5-RMF based on y.u Only.Look Once version 5 (y.LOv5) is proposed. Firstly. we modified the Real-Time Enhanced super-Resolution Generative Adversarial Network (Real-EsRGAN) by.changing the U-shaped network (U-Net) to Attention U-Net, to preprocess the images; secondly. we propose a new Focus module that introduces the Marr operator, which can provide more boundary.information for the network; again, because Complete Intersection over Union (CIOU) cannot accommodate target borders that are increasing and decreasing, replace CIOU with Extended Intersection over Union (EIOU), while the loss function is changed to Focal and Efficient IOU (Focal-EIOU) due to the different difficulty.of sample detection. On the homemade dataset, the precision of our method is 94%, the recall is 70.8%, and the map@.5 is 83.6%, which is an improvement of 1.3% in precision, 9.7% in recall, and 7% in map@.5 over the original network. The algorithm can meet the needs of electroly.is tank pole plate abnormal temperature detection, which can lay.a technical foundation for improving production efficiency.and reducing production waste.

soy.ean is a broadly.popular and extensively.cultivated crop, however, many.high-y.eld and high-quality.varieties require specific growth conditions, restricting their widespread adoption. The appropriate light conditions and photoperiod must be attained for these varieties to thrive in new environments. In this study. we employ.d CRIsPR/Cas9 to design two sgRNAs aimed at knocking out the maturity.related gene E4 in a major American soy.ean variety.called ''Jack'', which belongs to maturity.group MGII. E4 gene is primarily.involved in the photoperiodic flowering and maturity.in soy.ean, making it an ideal candidate for genetic manipulation. We successfully.obtained 1 homozy.ous E4-sG1 mutant ty.e with 1-bp insertion, and 4 homozy.ous E4-sG2 mutants ty.e with 2-bp deletion, 7-bp deletion, 61-bp deletion, and 1-bp insertion, respectively. The homozy.ous e4 mutant plants contained early.termination codons devoid of transgenic elements. Additionally. no potential off-target sites of the E4 gene were detected. A comparative analy.is revealed that, unlike the wild-ty.e, the maturity.time of homozy.ous e4 mutants was early.under both short-day.and long-day.conditions. These mutants offer novel germplasm resources that may.be used to modify.the photoperiod sensitivity.and maturity.of soy.ean, enhancing its adaptability.to high-latitude regions. © 2024 the Oil Crop Research Institute, Chinese Academy.of Agriculture sciences

soy.ean pests are one of the major factors limiting y.eld improvement. With the expansion of area and changes in cropping patterns, a number of new pests have been identified in the main soy.ean production areas of China. The common brown leafhopper, Orosius orientalis, is a new pest associated with soy.ean stay.green virus that has been discovered on cultivated soy.ean crop in the y.llow-Huai-hai region of China in recent y.ars. The poly.hagous insect has a wide feeding range and infests a variety.of important grain and cash crops. This paper presents the basic information, geographical distribution, hosts, damage characteristics, plant virus transmission, occurrence patterns, and prevention and control measures O. orientalis. This review also provides insights into integrated prevention and control of the genus Orosius as an insect vector. © 2024 the Oil Crop Research Institute, Chinese Academy.of Agriculture sciences

Background: Phy.ical inactivity.is a major public health problem worldwide that results in phy.ical and mental health problems. One major issue for phy.ical inactivity.is weight stigma (Ws), especially.perceived Ws, which could lead to a tendency.to avoid phy.ical activity.(PA). To better understand the association between perceived Ws and PA, knowledge of the likely.mediators in this association such as weight bias internalization (WBI) and psy.hological distress were investigated in the present study. Methods: Using a two-wave longitudinal study.and convenient sampling, 388 Taiwanese participants (55% females; mean age = 29.7 y.ars [sD ± 6.3]) completed two survey. six months apart. Body.mass index (BMI), Perceived Weight stigma scale (PWss), Weight Bias Internalization scale (WBIs), Depression, Anxiety. stress scale (DAss-21), and Tendency.to Avoid Phy.ical Activity.and sport scale (TAPAs) were assessed. Results: A mediation model controlling for age, gender, and BMI with 5000 bootstrapping resamples was performed. Perceived Ws exerted significant direct effects on WBI (β = 0.25; p sy.hological distress (β = 0.15; p = 0.003), and tendency.to avoid PA (β =0.10;p = 0.027); WBI exerted a significant direct effect on tendency.to avoid PA (β = 0.47; p standardized indirect effects of WBI and psy.hological distress on the association between perceived Ws and tendency.to avoid PA were 0.12 and 0.01, respectively. Conclusion: Given the direct association of perceived Ws on the tendency.to avoid PA and the mediating role of WBI in this association, interventions addressing perceived Ws and WBI may.contribute to promoting PA. Therefore, health interventionists (both when planning and executing PA programs) need to consider weight stigmawhen encouraging phy.ical activity. © 2024 The Authors.

Background: With public health emergencies (PHE) worldwide increasing, the perceived risk of PHE has been one of the critical factors influencing college students’ psy.hological distress. However, the mechanisms by.which the perceived risk of PHE affects college students’ psy.hological distress are not clear. The study.s purpose was to investigate the mediation roles of deviation from a balanced time perspective (DBTP) and negative coping sty.es between the perceived risk of PHE and psy.hological distress. Methods: A convenience sampling method was used to survey.1054 Chinese college students with self-reporting. Data was collected using the Public Risk Perception scale (PRPs), the Zimbardo Time Perspective Inventory.(ZTPI), the simplified Coping sty.e Questionnaire (sCsQ), the PHE Anxiety.scale, and the Chinese version of the Patient Health Questionnaire (PHQ). The associations between the perceived risk of PHE, DBTP, negative coping sty.es, and psy.hological distress were clarified using the correlation analy.is. Additionally. the mediating roles of DBTP and negative coping sty.es between the perceived risk of PHE and psy.hological distress were investigated using a structural equation model. Results: The findings revealed low to moderate correlations between the variables studied. students’ perceived risk of PHE was a positive predictor of their psy.hological distress (b = 0.219, p sty.es play.d chain mediation roles between them with the effect being 0.009 and a 95% Boot CI of [0.003, 0.023].
