Abstract Quantum interference effect serves as a critical strategy for addressing incorrect energy level alignment between frontier molecular orbital and electrodes in junctions. Weak-coupling structures offer an effective approach to suppress phonon thermal conductance. Thermoelectric properties of pure C 3 N 4 nanoribbon device _C 20 junctions are systematically investigated based on density functional theory (DFT) combined with non-equilibrium Green's function (NEGF) formalism. The...
For the problems of inaccurate recognition and high missed detection rate existing mask algorithms in actual scenes, a novel algorithm based on YOLO-GBC network is proposed. Specifically, backbone part, global attention mechanism (GAM) integrated to improve ability extract key information through cross-latitude interaction. The cross-layer cascade method adopted feature pyramid structure achieve effective bidirectional cross-scale connection weighted fusion. sampling content-aware reassembly...
In this paper, we propose and demonstrate a convenient flexible approach for preparation large-area of photonic crystals (PhCs) structures on the GaN-based LED chip. The highly-ordered porous anodic alumina (AAO) with pitch wavelength scale was adopted as selective dry etching mask PhCs-pattern transfer. PhCs different pore depths were simultaneously formed entire surfaces chip including ITO, GaN surrounding contacts sidewall mesa by one-step reactive ion (RIE). light output power...
Surface Plasmon microscopy can measure local changes of refractive index on the micron scale.Interferometric plasmon imaging delivers quantitative high spatial resolution sensitive to index.In addition so called V(z) method allows image contrast be controlled by varying sample defocus without substantially degrading resolution.Here, we show how a confocal system provides simpler and more stable alternative.This system, however, places greater demands dynamic range system.We therefore use...
To improve surface light extraction of GaN-based flip-chip light-emitting diodes (FC-LEDs), we employed an imprint approach thermosetting polymer for patterning microscale grating on the encapsulant. One-dimensional (1-D) and two-dimensional (2-D) taper-like gratings with a period 6 mum were successfully realized encapsulant above sapphire backplane GaN LED. By adopting 1-D 2-D encapsulant, improvement from 1 mm times FC-blue LED reflective Ag film p-side was about 18.5% 31.9% compared to...
As disease diagnosis becomes more sophisticated, there is a requirement to measure small numbers of molecules attached to, for instance, an antibody. This requires sensor capable not only high sensitivity but also the ability make measurements over highly localized region. In previous publications, we have shown how modified confocal microscope allows one surface plasmon (SP) on scale far smaller than propagation distance. The present implementation presents new ultrastable interferometer...
Codonopsis Radix (CR) is an edible food and traditional Chinese herb medicine in China. Various varieties of have different tastes. To make the flavor processed stable, two kinds electronic sensory devices, nose tongue, were used to establish a discrimination model identify botanical origin each sample. The optimal built on 88 batches samples was selected from models trained with all combination pretreatment methods three classification methods. A comparison performed data collected by...
Arterial stiffness has been proved to be an important parameter in the evaluation of cardiovascular diseases, and Pulse Wave Velocity (PWV) is a strong indicator arterial stiffness. Compared regional PWV (PWV among different arteries), local within single artery) outstands providing higher precision indicating properties, as PWVs are highly affected by multiple parameters, e.g., variations blood vessel lengths due individual differences, reflection effects on pulse waveform. However,...
This review highlights the factors that can dictate properties of cluster-based catalysts towards coupling reactions, such as ligand effect, doping support and defective effect.
In previous publications [Opt. Express 20, 7388 (2012), Opt. 28039 (2012)] we showed how a confocal configuration can form an surface plasmon microscope involving interference between path the generation of plasmons and one directly reflected beam. The relative phase these contributions changes with axial scan position allowing velocity to be measured. this paper extend interferometer concept produce 'embedded' shifting interferometer, where control reference beams spatial light modulator....
To describe the identification of two carbapenem-resistant, NDM-1 and IMP-4, carbapenemases coproducing Enterobacteriaceae isolates recovered from hospitalized patients in China. Both Klebsiella pneumoniae clinical (Kpn922 Kpn9599) were resistant to meropenem imipenem subjected additional antibiotic susceptibility testing. Polymerase chain reaction (PCR) sequence analyses used characterize bacterial carbapenemase resistance genes, extended-spectrum β-lactamases, plasmid-mediated AmpC...
In this paper, studies on the synchronization of fractional-order Takagi–Sugeno (T-S) fuzzy neural networks are performed. By employing a linear matrix inequality and constructing skillful Lyapunov function, sufficient conditions derived to guarantee that master system synchronizes slave system. Finally, an example its simulations presented demonstrate feasibility scheme.
ABSTRACT Two cases of pulmonary infection due to strains multidrug-resistant Klebsiella pneumoniae were investigated. Beta-lactamase determinants, such as bla IMP-4 and SHV-12 , the 16S rRNA methyltransferase-encoding gene armA detected in these plasmid-bearing organisms. The integron-borne contained intervening sequences highly related those a Vibrio cholerae O139 plasmid found Hangzhou, China.
To improve the light transmission from surface, we report a facile and cost-effective approach for formation of wavelength-scale conical pillar arrays on large surface area epoxy resin. The highly ordered with pitch about 460 nm height 800 have been successfully fabricated by technique shape-controlled anodization Al foil followed hot embossing. By replicating tapered pore onto transparent semi-cylindrical structure, incident angular resolved has obtained. integrated as high 62.2% achieved...
Emergency transportation plays a vital role in the success of disaster rescue and relief operations, but its planning scheduling often involve complex objectives search spaces. In this paper, we conduct survey recent advances bio-inspired meta-heuristics, including genetic algorithms (GA), particle swarm optimization (PSO), ant colony (ACO), etc., for solving emergency problems. We then propose new hybrid biogeography-based (BBO) algorithm, which outperforms some state-of-the-art heuristics...
