Owing to their controlled mobility, extensive coverage and low cost, unmanned aerial vehicles (UAVs) have significant promise in the field of military, civilian commercial applications, which has sparked a lot research interest. This paper explores application UAV symbiotic radio (SR) system. Specifically, we study multi-user SR system assisted by intelligent reflecting surface (IRS), modulation scheme with high flexibility is adopted embed IRS symbols into signals. First, focus on...
Power equipment maintenance work orders are vital in power management because they contain detailed information such as specifications, defect reports, and specific activities. However, due to limited research into automated extraction, valuable operational data remain underutilized. A key challenge is recognizing unstructured Chinese texts filled with specialized abbreviated terms unique the sector. Existing named entity recognition (NER) solutions often fail effectively manage these...
Due to the high propagation path loss in millimeter wave (mm-wave) system, it is necessary use large antenna array for obtaining beamforming gain mm-wave systems. In order reduce cost and complexity of hardware, an architecture called hybrid precoding proposed, which divides operation into analog domain digital domain. However, this poses a challenge channel estimation addition, due great amount users antennas, feedback overhead also issue that needs be considered. letter, we consider...
To investigate the risk spillover effect from crude oil market to BRICS stock markets, we extend Copula-CoVaR models by introducing Peak-over-Threshold and construct Copula-POT-CoVaR model. By using data 2006 2016 as sample, empirical study results show that: (a) model is an effective method measure extreme risk, (b) there a significant of explains more than 50 percent markets' (c) within five Russia's China's receive strongest slightest respectivlely. These findings indicate that close...
Symbiotic radio (SR), a new green communication technology, is proposed to address staggering amount of energy and spectrum resource requirements from massive Internet Things (IoT) devices, where some passive backscatter devices form backscatter-link transmissions. The aim this letter solve the pilot design channel estimation issues for SR system. To end, we propose novel joint (JPDCE) scheme based on deep learning, which consists designer estimator. Moreover, residual network successive...
A new braided poly lactic-co-glycolic acid (PLGA) (LA : GA = 10 90) catheter, consisting of an outside-tube and inside-scaffold, was designed fabricated to guide support peripheral nerve regeneration. According the process regeneration, functional division inside-scaffold confirmed as follows: major function for space regeneration needed good compression performance simulation matrix bridge in process. Therefore, a higher density with PLGA ply yarns coated chitosan; lower single filaments...
Many complex real-time systems, such as increasingly automated vehicles and 5G wireless base stations, contain a large amount of shared resources that must be accessed in mutually exclusive fashion. This leads to significant contention especially when are across processors. To reduce the contention, various resource-aware task allocation methods have been developed localize resources. Unfortunately, these existing either tailored for specific scheduling analysis approaches, or introduce...
Abstract Technology in food production is constantly evolving and advancing, the emerging genetically modified (GM) technology making a significant contribution to solving world’s problems. However, sporadic safety incidents negative media coverage have caused Chinese consumers remain apprehensive about of GM technology, even extent that they are reluctant buy vegetables unusual shapes because believe produced by technology. This paper examines this association with food. The results show...

A novel series of chiral dopants synthesised from (S)-1, 2-propanediol and mesogenic carboxylic acids were characterised by Fourier transform infrared 1H nuclear magnetic resonance, their helical twisting properties investigated doping the into a nematic liquid crystal host (SLC-1717). The results showed that values molecular power β significantly dependent on nature terminal substituents, alkyl length numbers centres in structure. Compared to compounds with electron-with-drawing groups...
Due to its ability significantly improve the wireless communication efficiency, intelligent reflective surface (IRS) has aroused widespread research interest. However, it is a challenge obtain perfect channel state information (CSI) for IRS-related channels due lack of send, receive, and process signals at IRS. Since most existing estimation methods are developed cascaded base station (BS)-IRS-user devices (UDs) channel, this paper studies problem computation resource allocation IRS-assisted...
