Cable termination is an important part of energy transmission in high-speed trains, and it is also a weak link in the insulation. It is important to determine the insulation status of cable terminals by the detection results of partial discharge signals, but the partial discharge signals in the field test circuit are mixed with a large amount of external corona interference, which affects the detection accuracy. This paper proposes a signal recognition model that incorporates Stockwell transform (ST) and 2DCNN, which in combination with wavelet noise reduction can achieve a high-precision classification effect for partial discharge and corona interference with an accuracy rate of up to 98.

An environmentally friendly flame retardant coating for polyurethane composed of ammonium polyphosphate(APP)/montmorillonite(MMT)/(3-aminopropyl)triethoxysilane(APTES) has been prepared by deposition on a polyurethane surface through a one-step immersion, enhancing its flame retardancy. The coating of APP/MMT/APTES on the polyurethane sample surface has been verified from XPS and FTIR analysis. In comparison to untreated polyurethane, the amount of char residue after combustion of the flame-retardant polyurethane increases significantly, with a 50.

Electrochemical conversion of carbon and nitrogen sources into valuable chemicals provides a promising strategy for mitigating CO emissions and tackling pollutants. However, efficiently scaling up C-N products beyond basic compounds like urea remains a significant challenge. Herein, we upgrade the C-N coupling for acetamide synthesis through coreducing CO and nitrate (NO) on atomic-scale Cu dispersed on boron nitride (Cu/BN) nanosheets.

The heterogeneity of thrombi in terms of composition, structure, and blood rheology parameters presents a challenge for effective thrombus-targeting drug delivery. To address this, a self-adaptive nano-delivery system, termed D-PLT, is developed. It consists of platelet membrane-cloaked deformable mesoporous organic silicon dioxide nanocomposite, enabling it to respond to the challenge of the heterogeneity of thrombi in arteries and veins.

Background: Cell death modulates the biological behaviors of tumors. However, the comprehensive role of the multiple forms of cell death in lower-grade glioma (LGG) is unknown.

Methods: We collected the transcriptional data of LGG patients from public repositories to comprehensively examine six cell death patterns (autophagy, apoptosis, cuproptosis, necroptosis, ferroptosis, and pyroptosis) in LGG samples and systematically correlated these patterns with patient survival, underlying biological processes, and drug sensitivity using serial bioinformatics analysis, clinical sample validation and assays.

  • The study looked at two medicines, bivalirudin and heparin, to see which one is safer and better for patients with a serious heart problem called STEMI who are getting a treatment called PCI.
  • Many patients didn't use a certain type of medicine (GPI) during the treatment, and those on bivalirudin had better results with fewer deaths and less bleeding.
  • However, for those who needed the GPI medicine, there weren't big differences in the results between the two treatments.

Article Synopsis
  • A new epoxy functionalized ionic liquid, MGM[TFSI], has been created to improve the stability of aqueous Zn-ion batteries (ZIBs) by reducing water reactivity and maintaining anode integrity.
  • The MGM cation disrupts water's hydrogen bonding, preventing its adsorption on Zn anodes, which helps control dendrite growth and enhances the formation of a protective ZnF layer.
  • With this improved electrolyte, Zn//Zn cells demonstrate over 2000 hours of stable cycling, and Zn//MnO full cells maintain about 89% capacity after 3000 cycles at high current rates.

Aim: This study aimed to investigate the separate and joint associations of triglyceride-glucose (TyG) index accumulation and variability with prediabetes and diabetes risk.

Methods: Health check-up participants who underwent 3 sequential health examinations during 2012-2016 and were followed up from 2017 to 2021 were enrolled and categorized into two subcohorts: (a) progression from normoglycaemia to prediabetes subcohort (n = 9373) and (b) progression from prediabetes to diabetes subcohort (n = 4563). Cumulative TyG (cumTyG) and TyG variability from Exams 1-3 were the exposures of interest in our study.

Flexible and high-performance aqueous zinc-ion batteries (ZIBs), coupled with low cost and safe, are considered as one of the most promising energy storage candidates for wearable electronics. Hydrogel electrolytes present a compelling alternative to liquid electrolytes due to their remarkable flexibility and clear advantages in mitigating parasitic side reactions. However, hydrogel electrolytes suffer from poor mechanical properties and interfacial chemistry, which limits them to suppressed performance levels in flexible ZIBs, especially under harsh mechanical strains.

The performance-degradation pattern of the planetary roller screw mechanism (PRSM) is difficult to predict and evaluate due to a variety of factors. Load-carrying capacity, transmission accuracy, and efficiency are the main indicators for evaluating the performance of the PRSM. In this paper, a testing device for the comprehensive performance of the PRSM is designed by taking into account the coupling relationships among temperature rise, vibration, speed, and load.

Radiated tumor cell-derived extracellular vesicles (RT-EVs) encapsulate abundant DNA fragments from irradiated tumor cells, in addition to acting as integrators of multiple tumor antigens. Accumulating evidence indicates these DNA fragments from damaged cells are involved in downstream immune responses, but most of them are degraded in cells before incorporation into derived RT-EVs, thus the low abundance of DNA fragments limits immune responses of RT-EVs. Here, this study found that different radiations affected fates of DNA fragments in RT-EVs.

  • The dynamic crystalline material displays exceptional mechanical resilience, allowing it to undergo significant elastic deformation (up to 2.6%) and recover its original shape without damage, showcasing excellent elasticity and the ability to twist and bend.
  • Its thermal mode involves precise control over phase boundaries based on temperature, leading to various motions such as shear deformation, with different effects depending on the alignment of the boundaries (thermomechanical or thermosalient).
  • The material can also switch structures in response to light through photochemical processes, enabling rapid bending when exposed to UV light and contributing to its diverse mechanical responses; this is made possible by minor structural changes and weak hydrogen bonds that preserve its long-range order.

The advancement of graph neural networks (GNNs) has made it possible to accurately predict metabolic sites. Despite the combination of GNNs with XGBOOST showing impressive performance, this technology has not yet been applied in the realm of metabolic site prediction. Previous metabolic site prediction tools focused on bonds and atoms, regardless of the overall molecular skeleton.

Article Synopsis
  • Vascular calcification (VC) in diabetes is driven by the switching of vascular smooth muscle cells to an osteogenic phenotype, which can be mitigated by mitophagy, a process that cleans up damaged mitochondria.
  • This study evaluates how the GLP-1 receptor agonist exendin 4 (EX4) impacts mitophagy-related phenotype switching in VSMCs, using T2DM mice models and cultured human cells under high glucose conditions.
  • EX4 was found to enhance mitophagy, improve mitochondrial function, and activate the AMPK signaling pathway, which collectively reduced VC in diabetic mice and inhibited the problematic osteogenic differentiation of VSMCs.
