Flexible surface-enhanced Raman scattering (SERS) substrates are very promising to meet the needs for real-time and on-field detection in practical applications. However, high-performance flexible SERS often suffer from complexity high cost fabrication, limiting their widespread Herein, we developed a facile method fabricate multicavity substrate composed of silver nanoparticle (AgNP)-decorated aluminum hydrous oxide nanoflake array (NFA) grown on polydimethylsiloxane (PDMS) membrane. Strong...

The prerequisite for rapid and steady development of TMDC-based optoelectronic devices is high efficiency in materials preparation, which relies on a mature synthesis technique optimized production conditions. Visualization based numerical simulation, illustrates the impact growth parameters deposited products, helpful to understand formation mechanisms modify In this work, we construct two models with different substrate placements, where parallel or perpendicular gas flow direction....

Online media outlets adopt clickbait techniques to lure readers click on articles in a bid expand their reach and subsequently increase revenue through ad monetization. As the adverse effects of attract more attention, researchers have started explore machine learning automatically detect clickbaits. Previous work detection assumes that all training data is available locally during training. In many real-world applications, however, generally distributedly stored by different parties (e.g.,...

A 13.3‐in. 8K Oxide TFT‐LCD with Smart View driving was reported in this paper. Based on the high performance of TFT and advanced design rule, transmittance could be improved 8% compared to traditional type. By driving, logical power saved 20% 4K resolution mode. The total lower 2.3W by technology. Meanwhile, panel border reduced 2.5mm because small design.

A new high-precision method to orient the ultrasonic linear array signals was proposed in this paper. First, FastICA algorithm used de-noise signals; then TCT is focus greatest extent cumulate position information of broadband signals, FastDOA estimate direction-of-arrival (DOA) focused narrowband speed up calculation after focusing; Then, application partial discharge detection using studied, estimated accuracy simulated with different SNR(Signal Noise Ratio) at first, results show that...

Two-dimensional (2D) monolayer transition metal dichalcogenides (TMDCs) that are compatible with Si-based substrates have already exhibited huge application potential in optoelectronics and photonics. The MoS2(1−x)Se2x ternary alloy consisting of two different chalcogens, as a class lasing gain medium, enriches the family 2D TMDC materials. Here, alloys tunable composition been synthesized via single-step chemical vapor deposition method. Raman photoluminescence studies demonstrate bandgap...

Integrating metal nanoparticles with vanadium dioxide (VO2) is an effective means to realize active plasmonic regulation which has great application potential in optical devices that respond real-time external stimuli. However, the high temperature necessary for VO2 growth severely reshapes nanoparticles, causing reduced refractive index (RI) sensitivity and degraded modulation performance. Herein, we construct a large-area dynamically tunable system composed of VO2-covered array hexagonal...

Transformer partial discharge ultrasonic array detection method is a new with high signal-to-noise ratio and reliability. But the influence of number to direction finding accuracy needs be further studied. Simulation angle 15 kinds sensor (-arrangement) under two conditions acute azimuth obtuse , study change rule different number, for example square planar sensor, based on an improved MUSIC(Multiple Signal Classification) algorithm. The results show that increases as rises, specific error...

Large power transformers as the hub of system equipment, its operation reliability directly related to security and stability system.

During software front-end development, the work to convert Graphical User Interface(GUI) image corresponding code is an inevitable tedious work. There have been some attempts make this be automatic. However, GUI generated by these models not accurate due lack of attention mechanism guidance. To solve problem, we propose PixCoder based on artificially supervised mechanism. The approach train a neural network predict style sheets in input and then output vector. generate targeting specific...

Abstract This paper proposes an Ethernet transmission method based on modified format, which is applied to the distribution domain protection system. By tagging data new identifications, has unique identity information in transmission. The switch replicates and transmit it two directions. When ring network destroyed, there no loss caused by switching direction. system realizes with seamless redundancy.
