First, composite buffer layer structure, including GaN AlGaN layer, used to improve the crystal quality DH. Second, interface roughness reduced increasing channel thickness, thus two-dimensional gas further improved. Moreover, an ultrathin AlN interlayer inserted between decrease...

In our previous work [J. S. Xue et al., Appl. Phys. Lett. 100, 013507 (2012)], superior electron-transport properties are obtained in InAlN/GaN/InAlN/GaN double-channel (DC) heterostructures grown by pulsed metal organic chemical vapor deposition (PMOCVD). this paper, we present a detailed fabrication and systematic characterization of high electron mobility transistors (HEMTs) fabricated on these heterostructures. The device exhibits distinct DC behavior concerning with both static-output...

Abstract Summary: The evolution of the morphologies in blends epoxy/4,4′‐methylenebis(2,6‐dimethylaniline)/polyethersulfone was followed by time‐resolved light scattering, optical microscopy and scanning electron microscopy. results suggest that, once diffusion epoxy molecules cannot follow geometrical growth, a secondary phase separation occurs, even droplet morphology, which size epoxy‐rich domain grows as usual. viscoelastic effect polyethersulfone is also discussed. Development OM:...

Background Among the primary goals of microarray analysis is identification genes that could distinguish between different phenotypes (feature selection). Previous studies indicate incorporating prior information genes' function help identify physiologically relevant features. However, current methods incorporate functional do not provide a relative estimate effect on biological processes interest. Results Here, we present method integrates gene ontology (GO) and expression data using...

In temporal compressive imaging (TCI), high-speed object frames are reconstructed from measurements collected by a low-speed detector array to improve the system speed. Compared with iterative algorithms, deep learning approaches utilize trained network reconstruct high-quality images in short time. this work, we study 3D convolutional neural for TCI reconstruction make full use of and spatial correlation among consecutive frames. Both simulated experimental results demonstrate that our can...

In the mid-wave infrared (MIR) band, large detector arrays are extremely costly and technically difficult to be manufactured. Thus, it is obtain high-resolution images for a conventional MIR camera. Spatial compressive imaging can improve resolution. However, system errors due misalignment or optical aberrations degrade reconstruction quality significantly. Another common issue slow speed, which caused by measurement collection processes. To deal with two issues, we use an calibration method...

Novel 1,2-di(pyridine-4-ly)ethyne pillared GO composites with high photocatalytic activity were achieved rare earth ions as interfacial linkers.

For applications such as remote sensing and bio-imaging, images from multiple bands can provide much richer information compared to a single band. However, most multispectral imaging systems have difficulty in acquiring for high-speed moving objects. In this paper, we use DMD-based temporal compressive (TCI) system obtain of objects over broad dual-band spectral range, the visible near-infrared (NIR) simultaneously. To deal with degraded reconstruction caused by optics, four nonuniform...

In this paper we report that the GaN thin film is grown by metal—organic chemical vapour deposition on a sapphire (0001) substrate with double AlN buffer layers. The layer consists of low-temperature (LT) and high-temperature (HT) are at 600 °C 1000 °C, respectively. It observed thickness LT-AlN drastically influences quality film, optimized 4.25-min-LT-AlN minimizes dislocation density film. reason for improved properties discussed in paper.

In this paper, we consider a distributed estimation of deterministic parameter vector in bandwidth constrained wireless sensor network.

In compressive imaging, the data acquisition speed of sensors is one restrictions limiting system imaging speed. To relax requirement sensors, we combine temporal and spatial sensing idea for block-wise imaging(BCI).

Task assignment is a critical part of human-robot collaboration. The traditional task methods in the intuitionistic fuzzy (IF) environment only consider two options, i.e., executed by humans or machines. However, some tasks may need to be completed and machines working together, such as mecha. Therefore, we propose method under IF based on three-way decision (3WD) theory this paper. By extending two-way mode into one, our can flexibly deal with concerned situations. At first, appropriateness...

In many situations, imagers are required to have higher imaging speed, such as gunpowder blasting analysis and observing high-speed biology phenomena. However, measuring video is a challenge camera design, especially, in infrared spectrum. this paper, we reconstruct high-frame-rate from compressive measurements using temporal (TCI) with compression ratio T=8. This means that, 8 unique frames will be obtained single frame reconstruction algorithm. Equivalently, the rates increased by times....
