Abstract This study aims to explore the effects of different non-landslide sampling strategies on machine learning models in landslide susceptibility mapping. Non-landslide samples are inherently uncertain, and selection may suffer from issues such as noisy or insufficient regional representations, which can affect accuracy results. In this study, a positive-unlabeled (PU) bagging semi-supervised method was introduced for sample selection. addition, buffer control (BCS) K-means (KM)...

Ice, cloud, and land elevation satellite (ICESat-2)/Advanced Topographic Laser Altimeter System (ATLAS) multibeam micropulse photoncounting light detection ranging (LiDAR) can be effectively applied to extract forest canopy height. However, the ICESat-2/ATLAS photon point cloud interfered with signal-to-noise ratio (SNR), fraction vegetation coverage (FVC), terrain slope. The main challenge of this research is high-precision heights. Therefore, article improves height extraction method based...

Hall thrusters are widely used as space electric propulsion devices. Due to the complex plasma phenomenon and high computation cost, currently it is difficult fully simulate real physical process in thrusters. Recently, Szabo Taccogna have proposed two different methods simplify accelerate simulation, respectively. In this paper, both these of acceleration analysed compared, then a modified method proposed. order verify acceleration, influence magnetic field gradient on parameter...

Landslide susceptibility assessment is used to predict the occurrence probability of landslides, and results can provide a scientific basis for preventing reducing landslides. Traditional models usually assume that contribution degree landslide influence factors fixed throughout an entire study area. Therefore, only compare relative weights different influencing factors, thereby ignoring changes in their contributions This paper introduces geographically weighted logistic regression (GWLR)...

Abstract The Fano resonance in single‐molecule junctions could be created by interaction with discrete and continuous molecular orbitals enables effective electron transport modulation between constructive destructive interference within a small energy range. However, direct observation of remains unexplored because the disappearance molecule‐electrode coupling. We demonstrated room‐temperature from electrochemical gated conductance current–voltage measurements para ‐carbazole anion...

A large number of defect states that exist at the interface between a perovskite film and an electron transport layer (ETL) are detrimental to efficiency stability solar cells (PSCs). It is still challenge simultaneously passivate defects on both sides by stable low-cost ion compound. Herein, we demonstrate simple effective versatile strategy introducing hydrochloric acid into SnO2 precursor solution in layers reduce energy barrier, ultimately achieving high-performance hysteresis-free PSCs....

To unveil the influence of metal coordination on charge transport and length-dependent conductance attenuation in π-conjugated organic molecules, trans-Ru(dppe)2 (dppe = 1,2-bis(diphenylphosphino)ethane) was implanted into oligoynyl chains with various number ethynyl groups to construct Au–molecule–Au junctions using methylthiol (−SMe) as anchoring groups. The single-molecule measured by I(s) method gave high low values conductance. A direct comparison indicates that implanting moiety...
