The tensile strength of loess, a key mechanical parameter for crack-related failures, has not received much attention in previous research, with the literature demonstrating a lack of systematic studies. Therefore, in this study, the variations in the tensile strength, crack distribution, crack numb...

In this paper, the dynamics of an acoustic bubble with a constant charge in compressible liquid are investigated numerically, which is based on the Gilmore-NASG model to estimate the radial oscillations. The cavitation effects are enhanced due to the presence of the charge on the bubble surface. The...

Diabetic nephropathy (DN) is a serious microvascular complication of diabetes and the main cause of end-stage renal disease. Smurf2 is a member of ubiquitin ligases. In this study, we aimed to investigate the mechanism by which Smurf2 mediated the development of DN. C57BL/6 mice were intraperitoneal...

Accurate feature matching between optical and synthetic aperture radar (SAR) images remains a significant challenge in remote sensing due to substantial modality discrepancies in texture, intensity, and geometric structure. In this study, we proposed an attention-context-aware deep learning framewor...

A double-resonant metal–insulator–metal (MIM) optical antenna is theoretically proposed to control the emission directivity of a dipolar emitter. The nanoantenna consists of an in-plane side-by-side assembling metallic nanobar dimer on the top and a metallic nanoplate on the bo...

We investigate the dynamical stability of the S-type planet in the compact binary HD 41004. Using N -body simulations, we find that the planet could be dynamically stable at a mutual inclination angle of up to ∼75°. The von Zeipel–Lidov–Kozai (vZLK) mechanism becomes active when the mutual inclinati...

Phase retrieval is an important tool for image recovery techniques based on Fourier spectrum. Different iterative algorithms have been developed to retrieve phase information. However, due to the nonconvex feature of the phase optimization problem, it remains a challenge to globally obtain the optim...

Inter-basin water transfer (IBWT) and groundwater exploitation reduction (GWER) are changing the surface and subsurface hydrological processes in the North China Plain (NCP), but groundwater quality variability with the impacts of IBWT and GWER remains unclear. To address this issue, a total of 209...

The main influencing factors of fouling in coal gasification black water systems were revealed by analyzing coal samples, scale samples, and black water gray water samples. In terms of coal quality, the ash in coal is the main source of scale, and the use of high-ash coal increases the tendency of f...

Cavitation has been widely used in wastewater degradation, material synthesis and biomedical field under dual-frequency acoustic excitation. The applications of cavitation are closely related to the power (i.e. the rate of internal energy accumulation) during bubble collapse. The Keller–Miksis equat...

Ectopic pancreas (EP) is most commonly located in the upper gastrointestinal tract, particularly in the stomach. Malignant transformation of EP is exceptionally rare, and due to its very low incidence, the response to drug therapy and overall prognosis remain poorly understood. This report presents...

Using high-precision photometric data from the Transiting Exoplanet Survey Satellite, medium-resolution spectroscopic data from the Large Sky Area Multi-Object Fiber Spectroscopy Telescope, and long-term eclipse timings, we provide orbital parameters for two early-type detached eclipsing binary syst...

BackgroundThe introduction of novel strategies for neoadjuvant therapy (NAT) has significantly enhanced the rate of pathological complete response (pCR) in patients with triple-negative breast cancer (TNBC). However, due to tumor heterogeneity, some patients continue to experience poor treatment eff...

Under the background of climate change, the risk spillover within the energy system is constantly intensifying. Clarifying the coupling relationship between entities within the energy system can help policymakers propose more reasonable policy measures and strengthen risk prevention. To estimate the...

The pervasive accumulation of polyethylene terephthalate (PET) waste has emerged as a critical ecological crisis, which is mainly driven by its recalcitrance to natural degradation and widespread contamination of terrestrial and aquatic ecosystems. In response to this challenge, microbial-mediated P...

<h4>Background</h4>Several prospective observational studies suggest that gamma-glutamyltransferase(GGT) level is positively associated with risk of hypertension. However, these studies draw inconsistent conclusions. Therefore, we conducted a systematic review and meta-analysis to evalua...

Iron is a redox-sensitive element and plays a critical role in governing the abiotic natural reduction of organic contaminants in aquifers. However, proper quantification and prediction of contaminant attenuation processes mediated by Fe species remain inadequately characterized, particularly under...
