The present study examined the usage of deep convolutional neural networks (DCNNs) for the classification, segmentation, and detection of the images of surface defects in heritage buildings. A survey was conducted on the building surface defects in Gulang Island (a UNESCO World Cultural Heritage Site), which were subsequently classified into six categories according to relevant standards. A Swin Transformer- and YOLOv5-based model was built for the automated detection of surface defects. Experimental results suggested that the proposed model was 99.2% accurate at classifying plant penetration and achieved a mean intersection-over-union (mIoU) of over 92% in relation to moss, cracking, alkalization, staining, and deterioration, outperforming CNN-based semantic segmentation networks such as FCN, PSPNet, and DeepLabv3plus. The Swin Transformer-based approach for the segmentation of building surface defect images achieved the highest accuracy regardless of the evaluation metric (with an mIoU of 90.96% and an mAcc of 95.78%), when contrasted to mainstream DCNNs such as SegFormer, PSPNet, and DANet.

Background The elderly are a priority population for COVID-19 vaccination. COVID-19 vaccination can effectively reduce the risk of developing severe and critically ill patients or even death in COVID-19 patients. However, the current vaccination rate of the elderly in China is relatively low, and the COVID-19 vaccination behavior among the elderly has been rarely reported in current studies. Objective To investigate COVID-19 vaccination behavior and its influencing factors among the elderly in China, and to provide a reference for improving the COVID-19 vaccination rate of the elderly. Methods A total of 1 323 older adults aged 60 years and above in Wujin District of Changzhou City, Zhongmu County of Zhengzhou City, Chengzhong District of Xining City and Linkou County of Mudanjiang City were selected as research subjects from August 3 to August 14 in 2022 by using a stratified random sampling method and investigated by self-designed questionnaires. Binary Logistic regression analysis was used to explore the influencing factors of the first dose of COVID-19 vaccination, full course of COVID-19 vaccination, and booster dose of COVID-19 vaccination. Results 96.60% (1 278/1 323) of the elderly received the first dose of COVID-19 vaccine, 91.76% (1 214/1 323) completed the full course of COVID-19 vaccination, and 79.67% (1 054/1 323) received the booster dose of COVID-19 vaccine. The results of binary Logistic regression analysis showed that compared with the older adults aged 60-64 years, the older adults aged 75 years and above were less likely to receive the first dose of the COVID-19 vaccine〔OR (95%CI) =0.27 (0.11, 0.62), P

Most forest soils contain substantial amounts of gravel. However, unlike the more widely known root resource uptake behaviors which respond to resource patches in substrate without gravels, how roots respond to substrate containing different gravel levels is poorly understood. We grew roots in substrates with five gravel levels (0%, 10%, 20%, 30%, and 40% of volume) in a subtropical Schima superba Gardn. et Champ plantation, determined fine root dynamics and turnover rate with minirhizotrons, measured fine root morphological, architectural, mycorrhizal colonization, chemistry, and mass allocation. The presence of gravel in the substrate delayed the timing of peak root growth. In the substrate with higher gravel content, plants produced more in roots in autumn, but there were fewer roots in summer and the roots tended to exhibit lower fine root turnover rate and mycorrhizal colonization, but higher root biomass allocation. The higher root biomass in the substrate with higher gravel content was associated with higher root carbon/nitrogen ratio. Our findings emphasize the complexity of root resource uptake behavior in response to gravel content and suggest that incorporating substrate gravel content into root studies may help to improve the prediction of patch exploitation and nutrient acquisition in stony soils. Key words: heterogeneous patches, root phenology, root morphology, root architecture, mycorrhizal colonization. La plupart des sols forestiers contiennent des quantites substantielles de gravier. Cependant, contrairement aux comportements plus largement connus concernant le prelevement des ressources par les racines qui reagissent a des ilots riches en ressources dans un substrat exempt de gravier, la facon dont les racines reagissent a un substrat qui contient differentes quantites de gravier est mal connue. Nous avons fait croitre les racines dans des substrats contenant differentes proportions (cinq) de gravier (0%, 10%, 20%, 30% et 40% du volume) dans une plantation subtropicale de Schima superba Gardn. et Champ; determine la dynamique et le taux de renouvellement des racines fines a l'aide de minirhizotrons; mesure la morphologie, l'architecture, la colonisation mycorhizienne et les caracteristiques chimiques des racines fines ainsi que la repartition de la biomasse. La presence de gravier dans le substrat a retarde le moment ou la croissance des racines a atteint son niveau maximum. Dans le substrat contenant le plus de gravier, la plus forte croissance est survenue dans les racines a l'automne. Par contre les racines etaient moins abondantes durant l'ete et le taux de renouvellement ainsi que la colonisation mycorhizienne des racines fines avaient tendance a etre plus faibles, mais l'allocation de biomasse racinaire etait plus prononcee. La biomasse racinaire plus elevee dans le substrat contenant le plus de gravier etait associee a un rapport carbone:azote plus eleve dans les racines. Nos resultats font ressortir la complexite du comportement relie au prelevement des ressources par les racines en reaction a la teneur en gravier et indiquent que l'incorporation de la teneur en gravier du substrat dans les etudes portant sur les racines pourrait contribuer a ameliorer la prediction de l'exploitation des ilots riches en ressources et l'acquisition des elements nutritifs dans les sols pierreux.

The book "Obesity in the news: Language and Representation in the Press" by Brookes and Baker provides a linguistic perspective on media representations of obesity. The authors analyze a large dataset of obesity news articles and readers' comments from 2008 to 2017. They examine discursive patterns, shifts over time, and differences between different types of newspapers. The book also explores the stigmatization of people with obesity, representations of weight loss, gendered identities, social class, and reader comments. Overall, the book offers valuable insights into press representations of obesity and provides recommendations for journalists and readers. [Extracted from the article]

Fluid mechanics is a fundamental course in many disciplines such as civil engineering and hydraulic engineering, with broad applicability and practical significance in engineering. However, the abstractness and multiplicity of its basic concepts hinders students' first-hand experience during traditional classroom learning, and the time and space limitation of its offline experiment often results in unsatisfying teaching effectiveness. To address these challenges, a set of virtual simulation experiment system is developed for the course of fluid mechanics, along with an external support system to maximize its performance. Evaluation based on curriculum objective achievement shows that this experimental system has significantly improved the teaching effectiveness for the course of fluid mechanics. It promotes students' independent learning skills and their ability utilizing fluid mechanics knowledge to understand, simplify and solve practical engineering problems. [ABSTRACT FROM AUTHOR]

Sirtuin 6 (SIRT6) plays a critical role in the progression and development of gastrointestinal cancers. However, the association between SIRT6 expression and clinicopathological parameters and prognosis in gastrointestinal cancer patients remains inconclusive. Consequently, we conducted this meta-analysis to evaluate the importance of SIRT6 expression in various types of gastrointestinal cancers. PubMed, EMBASE, and Web of Science databases were systematically searched to screen the relevant literature. The reported or estimated hazard ratio (HR) and odds ratio (OR) and their corresponding 95% confidence interval (CI) were pooled to assess the strength of the association. Nine studies involving 867 patients were included in the meta-analysis. Overall analysis showed that high SIRT6 expression was related to better overall survival in gastrointestinal cancers (HR = 0.62, 95% CI = 0.47–0.82). High SIRT6 expression was also related to a favorable tumor node metastasis (TNM) stage (OR = 0.44, 95% CI = 0.28–0.70) among gastrointestinal cancer patients. Our meta-analysis revealed that high SIRT6 expression might be a potential biomarker predicting better prognosis in gastrointestinal cancers, which may offer options for gastrointestinal cancer treatment.
