Ultrathin graphitic carbon nitride (g-C3N4) nanosheets served as a novel matrix for the detection of small molecules by negative ion matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) was described first time. In comparison with conventional organic matrices and graphene matrix, use g-C3N4 nanosheet showed free background interference increased signal intensity in analysis amino acids, nucleobases, peptides, bisphenols (BPs), nitropolycyclic aromatic...
An iron-catalyzed fragmentation alkynylation, alkenylation and alkylation enabled by photoinduced ligand-to-metal charge transfer (LMCT)processis herein reported.
Accurately determining the distribution and quantity of maize straw types is great significance for evaluating effectiveness conservation tillage, precisely estimating resources, predicting risk burning. The widespread adoption tillage technology has greatly increased diversity complexity coverage in fields after harvest. To improve precision remote sensing recognition types, a novel method was proposed. This utilized unmanned aerial vehicle (UAV) multispectral imagery, integrated Stacking...
Electrocatalysis and photocatalysis have both emerged as increasingly feasible platforms in sustainable synthesis. This study explores a novel photoelectrochemical synergistic strategy, achieving non-directed C(sp3)–H alkenylation reaction utilizing an iron-cobalt dual...
Land subsidence is a global environmental geological hazard caused by natural or human activities. The high spatial resolution and continuous time coverage of interferometric synthetic aperture radar (InSAR) series analysis techniques provide data basis for the development methods investigation evolution mechanism study regional land subsidence. Beijing, capital city China, has suffered from decades since it was first recorded in 1950s. It reported that uneven ground fractures have seriously...
Human-machine interface(HMI) technology has gradually become a research hotspot with the continuous development of computer and Internet Things (IOT) technology. Hand gesture recognition (HGR) as an important part HMI been widely concerned. Among many technical routes HGR technology, wearable based on A-mode ultrasound shows great application potential due to its advantages such lightweight device, free from sensors' constraint etc. However, in process processing ultrasonic signal, amplitude...
Since the 1970s, land subsidence has been rapidly developing on Beijing Plain, and systematic study of evolutionary mechanism this is great significance in sustainable development regional economy. On basis Interferometric Synthetic Aperture Radar (InSAR) results, employed Mann–Kendall method for first time to determine mutation information Plain from 2004 2015. By combining hydrogeological conditions, “southern water” project, other data, we attempted analyse reasons mutations. First,...
Abstract This research focuses upon employment in the new economy, exploring labour protection and social digital age China. Through an empirical survey conducted three Chinese cities, insurance rights of employees economic sector, such as gig employment, e‐commerce, various other forms online have been examined in‐depth. study reveals regulatory loopholes market, which substantially eroded basis policy arrangements China, “softening” participation branches compliance with regulations...
Geological disasters, including ground deformation, fractures and collapse, are serious problems in coal mining regions, which have threatened the sustainable development for local industry. The Ordos Basin is most known its abundant resources. Over-mining underground resources had induced land deformation. Detecting evolution of deformation features identifying potential risk important decision-makers to prevent geological disasters. We analyzed subsidence by a 200 km 2 area time period...
At present, the research on gesture recognition based ultrasonic signals is mostly about static gestures. Compared with gestures, dynamic gestures reflect human intent more intuitively. However, speed difference of will cause a mismatch in time series. To tackle this problem, we proposed scheme warping (DTW) algorithm. First, forearm muscles were acquired by four A-mode transducers. Second, original underwent Gaussian filtering, feature extraction, normalization, and principal component...
A-mode ultrasound has the advantages of high resolution, easy calculation and low cost in predicting dexterous gestures. In order to accelerate popularization gesture recognition technology, we designed a human-machine interface that can interact with user real-time. Data processing includes Gaussian filtering, feature extraction PCA dimensionality reduction. The NB, LDA SVM algorithms were selected train machine learning models. whole process was written C++ classify gestures This paper...
Time-series monitoring of the land subsidence in Yangtze River coastal area is crucial for maintaining river stability and early warning disasters. This study employed PS-InSAR SBAS-InSAR techniques to monitor along Nanjing, using a total 42 Sentinel-1A images obtained between April 2015 November 2021. The accuracy both methods was compared validated, while comprehensive analysis conducted ascertain spatial distribution characteristics underlying causes subsidence. maximum deviation two six...
Over-exploitation of groundwater has caused severe land subsidence in Beijing during the past two decades. Since middle route South-to-North Water Diversion Project (SNWDP), biggest water diversion project China, started to deliver December 2014, shortage been greatly alleviated. This study aims analyze impact SNWDP on spatiotemporal evolution Beijing. Change surface displacement after was retrieved and patterns change were analyzed based long time-series Envisat Advanced Synthetic Aperture...
Abstract A novel approach was developed to quantitatively examine land subsidence. It combines a new geophysical (NG) prospecting and the interferometric synthetic aperture radar (InSAR) technology explore uneven development of subsidence in Beijing, China. We derived spatial information over 4 years (from November 2014 July 2018) based on Sentinel‐1 satellite imagery small‐baseline InSAR (SBAS‐InSAR) method. Also, profile data were acquired using seismic frequency resonance (SFR) few...
The global aging population is rapidly increasing, which has led to a growing prevalence of obesity among the elderly.
