Cubic quantum dot/hexagonal microsphere ZnIn₂S₄ heterophase junctions were prepared and exhibited significantly higher visible-light photocatalytic hydrogen evolution performance than single cubic or hexagonal ZnIn₂S₄.

An efficient strategy for the synthesis of benzofuro[2,3- b]pyrazines was developed. These tricyclic scaffolds were formed through a multistep cascade sequence, which includes double insertion isonitriles and chemoselective bicyclization. In this reaction, nanopalladium used as recyclable catalyst. Product 3w exhibited excellent anticancer activity toward T-24 (IC50 = 12.5 ± 0.9 μM) HeLa 14.7 1.6 cells. We also explored action mechanism on

In recent years, hundreds of Earth observation satellites have been launched to collect massive amounts remote sensing images. However, the considerable cost and time process significant amount data become greatest obstacle between knowledge. order accelerate transformation from images urban thematic maps, a strategy map bare land automatically Landsat imagery was developed assessed in this study. First, normalized difference index (NBLI) presented maximally differentiate other types Wuhan...

The sensitivity and accuracy of electrochemiluminescence (ECL) sensors for detecting small-molecule pollutants in environmental water are affected not only by nonspecific adsorption proteins other molecules but also bacterial interference. Therefore, there is an urgent need to develop ECL sensor with antifouling antibacterial functions environment monitoring. Herein, a highly efficient sensing interface (PSBMA@SiO2-MXene) based on zwitterionic sulfobetaine methacrylate (SBMA) nanospheres...

Pulsed electrocatalysis has emerged as a promising technology to effectively improve reaction kinetics and tailor product selectivity. While most research focuses on the evolution of electrocatalyst active sites, dynamic response interfacial microenvironment during pulsed still remains unknown. Here, we reveal in situ regulation induced by oxygen reduction process, from interface reactant delivery intermediate formation dynamics. At diffusion layer, coupling hierarchical pore structure was...

We study the creep properties of clastic soil in residual state. The intact samples are taken from a reactivated slow-moving landslide Three Gorges Reservoir Region, China. Firstly, patterns movement analysed based on recent monitoring data, which indicate that within shear zone is undergoing two deformation processes: phase, characterised by different rates, and dormant phase. then behaviour through series ring tests under various stress conditions. response depends strongly ratio to...

Abstract The year 2023 marked a significant surge in the exploration of applying large language model chatbots, notably Chat Generative Pre‐trained Transformer (ChatGPT), across various disciplines. We surveyed application ChatGPT bioinformatics and biomedical informatics throughout year, covering omics, genetics, text mining, drug discovery, image understanding, programming, education. Our survey delineates current strengths limitations this chatbot offers insights into potential avenues...

Abstract Emerging studies underscore the promising capabilities of large language model-based chatbots in conducting basic bioinformatics data analyses. The recent feature accepting image inputs by ChatGPT, also known as GPT-4V(ision), motivated us to explore its efficacy deciphering scientific figures. Our evaluation with examples cancer research, including sequencing analysis, multimodal network-based drug repositioning, and tumor clonal evolution, revealed that ChatGPT can proficiently...

Streamflow is an important factor in the study of water resource management, floods, and droughts. Dramatic climate change has created extreme rainfall distributions, making streamflow trends variability even more crucial. In this study, long-term data recorded at gauging stations Northern Taiwan are analyzed using Mann-Kendall test. The used for trend analysis average annual streamflow, seasonal high low flows. slope calculated Theil-Sen estimator. Finally, point conducted...

Roller shapes play a very critical role in the performance of antibacklash double-roller enveloping hourglass worm (ADEHW) gears; however, their influence is seldom reported literature. Based on theories differential geometry and gear meshing, this paper presents generic models meshing characteristics for ADEHW gears, including both contact curve tooth profile. We present different functions derivatives with respect to each drive type associated roller shapes. also compare effects curve,...

Abstract Shear behavior of rock mass greatly depends upon the joint roughness which is generally characterized by anisotropy, scale effect and interval effect. A new index enabling to capture all three features, namely brightness area percentage ( BAP ), presented express based on synthetic illumination a digital terrain model derived from terrestrial laser scanner (TLS). Since only tiny planes facing opposite shear direction make contribution resistance during failure, therefore these are...

Abstract Landslide-induced tsunamis may cause fatalities, damages and financial losses. In the Three Gorges Reservoir Area of China, several large landslides are still unstable persistently creeping toward Yangtze River. this paper, we investigate impacts landslide-induced in by using a hybrid numerical approach. One largest mass area, Huangtupo landslide, is chosen as study object. First, landslide deformation initiating velocities obtained finite-discrete element method. The their on...

A central challenge in face perception research is to understand how neurons encode identities. This has not been met largely due the lack of simultaneous access entire processing neural network and a comprehensive multifaceted model capable characterizing large number facial features. Here, we addressed this by conducting silico experiments using pre-trained recognition deep (DNN) with diverse array stimuli. We identified subset DNN units selective identities, these identity-selective...
