The unmanned aerial vehicle (UAV) is a promising enabler of the Internet Things (IoT) vision, due to its agile maneuverability. In this paper, we explore potential gain UAV-aided data collection in generalized IoT scenario. Particularly, composite channel model, including both large-scale and small-scale fading used depict typical propagation environments. Moreover, rigorous energy constraints are considered characterize devices as practically possible. A multiantenna UAV employed, which can...
3D nanoflower-like CuxO/multilayer graphene composites (CuMGCs) have been successfully synthesized as a new type of room temperature NOx gas sensor. Firstly, the expanded graphite (EG) was activated by KOH and many moderate functional groups were generated; secondly, Cu(CH3COO)2 CTAB underwent full infusion into interlayers EG (aEG) means vacuum-assisted technique then reacted with aEG accompanied exfoliation via reflux. Eventually, nanoflower consisting 5–9 nm CuxO nanoparticles...
In this paper, CeO2/graphene-like nanosheet composites (CeGNCs) have been synthesized via a facile solvothermal reaction. the synthesis, Ce(NO3)3 precursor was fully infused into interlayers of expanded graphite (EG) under vacuum-assisted conditions, and then CeO2 nanoparticles grow in situ inexpensive EG conditions to form CeGNCs. The results show that particles with an average diameter about 3 nm are highly dispersed on graphene-like (>10 layers). synergy between tiny size good...
Hydroxypropyl-β-cyclodextrin (HP-β-CD) modified graphene nanosheets were successfully prepared using a facile and rapid method assisted by microwave irradiation in water medium, which involves the reaction between carboxyl groups of oxide (GO) hydroxyl HP-β-CD followed reduction GO into reduced (RGO) utilizing hydrazine hydrate. The as-prepared HP-β-CD-RGO nanocomposites characterized Fourier transform infrared spectra, Raman X-ray photoelectron spectroscopy, thermogravimetric analyses,...
In the present work, nanocomposite ZnV2O4–CMK was synthesized for first time by using a low temperature carbothermal reduction route and then characterized means of X-ray diffraction (XRD), thermogravimetric analysis (TG), N2 adsorption–desorption, scanning transmission electron microscopy (SEM/TEM). Furthermore, used as an anode material Li-ion intercalation exhibited large reversible capacity, high rate performance cycling stability. A capacity 575 mA h g−1 maintained even after 200 cycles...
In the process of orthodontic clinical teaching, it is very important to teach medical students how they are expected communicate effectively with patients and their families, as this has a direct impact on patient compliance throughout diagnosis treatment satisfaction after treatment. Doctor-patient communication therefore an essential skill for gain before taking up work. view problems that often encountered in each stage treatment, present paper discusses specific content doctor-patient...
Polylactic acid (PLA) fiber membranes fabricated through electrospinning exhibit significant potential for air filtration. However, their efficiency in filtering highly permeable particulate matter (PM) is limited, as these particles can carry various bacteria and toxic substances. To address this challenge, the dielectric properties of PLA are enhanced by incorporating dodecyl trimethyl ammonium chloride (DTAC), leading to formation a bimodal micro/nanofiber structure via conjugated...
Early detection of fake news is crucial to mitigate its negative impact. Current research in often utilizes the difference between real and regarding support degree from reliable sources. However, it has overlooked their different semantic outlier degrees among unreliable source information during same period. Since serves idea propaganda, sources usually publish a lot with propaganda period, making less likely be outlier. To leverage this difference, we propose Reliable-Unreliable Source...

To accommodate exponentially increasing traffic demands, operators are seeking to offload cellular small base stations (BSs) in heterogeneous networks (HCNs), which is promising alleviating congestion. In HCNs, eager balance the globally, where users may be pushed less preferred BSs, resulting possible conflict with user local preference. Thus, it a big challenge achieve dynamic load balancing for and provide participation incentive simultaneously. Due dynamics of network state demand, we...
Glomerulosclerosis and renal interstitial fibrosis occur with the aging kidney.
