However, the increased blade size has also led to higher repair and maintenance costs, which demands efficient and reliable structural health monitoring techniques for wind turbine blades. Computer vision techniques have emerged as promising tools to address the key topics in blade structural health monitoring, including damage detection, damage localization, damage classification, and damage quantification. Despite recent advancements in both traditional computer vision methods and advanced approaches like deep learning, a comprehensive evaluation of the most effective computer vision techniques for structural health monitoring of wind turbine blades remains absent. This includes consideration of task-specific conditions such as environmental variability, computational requirements, and characteristics of different blade damages. This paper analyzes the strengths and limitations of state-of-the-art computer vision techniques for structural health monitoring of wind turbine blades, as well as the imaging modalities applicable to capturing different blade damages.

In this study, we report that the diastereoselective course of the Norrish-Yang reaction of imidazolidinone derivatives is reversed by the addition of tetrabutylammonium salts (TBAX). 1H NMR experiments suggested that cation-π interactions between TBA+ and the substrate control the reactive conformation of this latter species. In the course of this study, we found that unexpected compounds with 6/7/5- and 6/6/5-fused tricyclic systems containing an aromatic ring were also formed in the presence and absence of TBAX, respectively. Furthermore, we report the formation of an unexpected fused tetracyclic compound, the framework structure of which resembles that of a tetraquinane, when a substrate with 2-benzoylethyl side chains on both nitrogen atoms of the imidazolidinones is used.","PeriodicalId":57,"journal":{"name":"Journal of Organic Chemistry","volume":"77 1","pages":""},"PeriodicalIF":4.354,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, by developing a data-driven bottom-up coarse-grained model using discrete molecular dynamics simulations, we found proteins in the condensates of TDP-43 forming a dynamic network of fluctuating sizes. While dominated by peptides engaged with a small number of peptides connected by a low number of interpeptide contacts, the condensates also contained peptides with large numbers of connections, serving as hubs of a small-world network. Importantly, peptides in these high-contact states were intertwined to form oligomers that were stable for relatively long periods inside the weakly connected network. These oligomers were likely the aggregation intermediates toward nucleation of amyloid fibrils. Therefore, this transferable coarse-grained model may serve as a powerful tool for unraveling the inner workings of LLPS and amyloid aggregation.","PeriodicalId":62,"journal":{"name":"The Journal of Physical Chemistry Letters","volume":"9 1","pages":"7797-7806"},"PeriodicalIF":6.475,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated these associations and examined the mediating role of maternal and neonatal thyroid hormones in a Chinese birth cohort consisting of 501 mother-child pairs. We found that exposure to 2-hydroxy-benzothiazole (2-OH-BTH) in early pregnancy was inversely associated with childhood body mass index (BMI) (β = -0.041, 95% CI: -0.077, -0.005). Both tolyl-triazole (TTR) (β = -1.35%, 95% CI: -2.45%, -0.24%) and 2-OH-BTH (β = -1.15%, 95% CI: -1.79%, -0.50%) were inversely associated with maternal free thyroxine (FT4) in early pregnancy, which mediated 23.53% of the inverse associations between 2-OH-BTH exposure and childhood BMI. Additionally, third-trimester exposure to 1-hydroxy-benzotriazole, xylyl-triazole, TTR, and 2-OH-BTH was positively linked to neonatal thyroid-stimulating hormone levels. These findings suggest that prenatal exposure to BTs, particularly 2-OH-BTH, may impair early childhood growth by disrupting thyroid hormone homeostasis. Our results add new epidemiological evidence to the growing concern about BTs and underscore the importance of considering thyroid disruption as a mechanistic link between environmental exposures and developmental outcomes. This highlights the need for greater public health attention and regulatory measures targeting these emerging contaminants.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"16 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, fewer work has focused on the long non-coding RNAs (lncRNAs) sensing, which are most likely present in ISF and engage in the occurrence and development of Alzheimer's disease (AD). In this work, taking adenocarcinoma transcript 1 (MALAT1) as the representative of lncRNAs, which is abnormally down-regulated in AD patients, a robust hydrogel MN array - based fluorescent patch was developed for MALAT1 by integrating a methacrylated gelatin (GelMA) hydrogel MN as the extraction tool with a strand displacement reaction (SDR) mediated fluorescent probe. Specifically, the MNs were prepared by the simple and feasible photo-crosslinking of GelMA, which displayed satisfactory swelling capability for extracting ISF and mechanical strength to penetrate the skin's cuticle layer. Subsequently, a triplex SDR amplification probe was constructed for MALAT1 sensing. By mixing with the prepolymer solution, the MNs patch loaded with the fluorescent probe was fabricated, which demonstrated excellent sensing performances in both PBS and agarose simulated skin, with lower limits of quantification (LLOQ) of 7.62 and 13.24 nM, respectively. The developed MN patch was proved highly suitable for distinguishing the down-regulated MALAT1 expressions in ISF of AD mice. This work represented the first example to correlate the changes in the levels of MALAT1 in ISF with AD pathology, providing a practical tool for the early non - invasive diagnosis of AD.</div></div>","PeriodicalId":259,"journal":{"name":"Biosensors and Bioelectronics","volume":"288 ","pages":"Article 117823"},"PeriodicalIF":10.7,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144702248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
