Vehicle-to-vehicle safety communications based on the dedicated short-range communication technology have the potential to enable a set of applications that help avoid traffic accidents. The performance of these applications, largely affected by the reliability of communication links, stringently ties back to the MAC and PHY layer design, which has been(More)
Biodegradable and bioactive nanocomposite (NC) biomaterials with controlled microstructures and able to deliver special drugs have gained increasing attention in bone tissue engineering. In this study, the hydroxyapatite (HAp)/poly(l-lactic acid) (PLLA) NC scaffolds were facilely prepared using solvent evaporation from templating Pickering emulsions(More)
Self-healing hydrogels were proposed to be used as biomaterials, because of the capability of spontaneously healing injury, but most of the reported self-healing hydrogels do not possess high mechanical strength and fast self-healing at the same time. Herein, we prepared graphene oxide (GO)-hectorite clay-poly(N,N-dimethylacrylamide) (PDMAA) hybrid(More)
BACKGROUND Nanoparticle formulations of pesticides have been proposed to produce a better spatial distribution of the pesticide on leaf surfaces, which provides better efficiency. Nanoparticles are well studied for drug delivery and sustained release but not in the agricultural sciences, because of the difficulty in generating stable pesticide nanoparticles(More)
Wnt/β-catenin signaling is fundamental in embryogenesis and tissue homeostasis in metazoans. Upon Wnt stimulation, cognate coreceptors LRP5 and LRP6 ([LRP5/6] low-density lipoprotein receptor-related proteins 5 and 6) are activated via phosphorylation at key residues. Although several kinases have been implicated, the LRP5/6 activation mechanism remains(More)
Enterobacteriaceae produce antimicrobial peptides for survival under nutrient starvation. Microcin J25 (MccJ25) is an antimicrobial peptide with a unique lasso topology. It is secreted by the ATP-binding cassette (ABC) exporter McjD, which ensures self-immunity of the producing strain through efficient export of the toxic mature peptide from the cell. Here(More)
Polysaccharide multilayer microcapsules were fabricated in aqueous media by the layer-by-layer self-assembly of chitosan (CHI) and sodium alginate (ALG) on melamine formaldehyde (MF) microparticles of 2.1 microm diameter as templates, followed by removal of the templates through dissolving at low pH. The loading process was observed with the confocal laser(More)
Polyelectrolyte multilayer films were prepared through layer-by-layer (LbL) self-assembly using polysaccharide sodium alginate (ALG) and chitosan (CHI). After incubation in an enzyme pepsin solution, the multilayer film was partially destroyed as detected by the decrease in fluorescent intensity because of the enzymatic degradation of CHI. The enzymatic(More)
This paper investigates the throughput for wireless network with full-duplex radios using stochastic geometry. Full-duplex (FD) radios can exchange data simultaneously with each other. On the other hand, the downside of FD transmission is that it will inevitably cause extra interference to the network compared to half-duplex (HD) transmission. Moreover, the(More)
Artemisia argyi oil (AAO)-loaded antibacterial microcapsules with hydroxyapatite (HAp)/poly(melamine formaldehyde) (PMF) hybrid shells were facilely prepared by oil-in-water (O/W) Pickering emulsion templating. AAO-in-water emulsions were stabilized using HAp nanoparticles as the particulate emulsifier. The hybrid shells were fabricated by in situ(More)
