PageRank has been the signature unsupervised ranking model for node importance in a graph. One potential drawback of is that its computation depends only on input graph structures, not considering external information such as attributes nodes. This work proposes AttriRank, an considers structure but also AttriRank and domain-independent, which different from most existing works requiring either ground-truth labels or specific domain knowledge. Combining two reasonable assumptions about...
In this report, the development of physical vapor transport (PVT) methods for bulk aluminum nitride (AlN) crystal growth is reviewed. Three modified PVT with different features including selected at a conical zone, freestanding on perforated sheet, and nucleation control an inverse temperature gradient are discussed compared in terms size quality AlN crystals they can produce as well process complexity. The method able to significantly reduce rate realize dominant only one single crystal,...
It was well known that most of gamma-ray bursts (GRBs) are dominated by positive spectral lags, while a small fraction GRBs show negative lags. However, Wei et al. firstly identified well-defined transition from lags to in GRB 160625B, and then got robust limits on possible violation Lorentz Invariance (LIV) based the observation. Recently, such has been found three different emission episodes \thisgrb Gunapati al., which provides us great opportunity investigate whether results LIV-induced...
The AlGaN/GaN p–n junction has received extensive attention due to its capability of rapid photogenerated carrier separation in photodetection devices. heterojunction nanowires (NWs) have been especially endowed with new life for distinctive transport characteristics the photoelectrochemical (PEC) detection field. A self-powered PEC ultraviolet photodetector (PEC UV PD) based on p-AlGaN/n-GaN NW is reported this work. n-GaN layer plays a crucial role as current flow hub regulate transport,...
The ZnO film photosensitive chips prepared by sputtering method were post-treated air-anneal at different temperatures and Ar or air-plasma treatments for time. Then, packaged into UV photodetectors with a standard TO-5 package to meet the sensitivity, selectivity, stability standards. Noise analysis was used as an efficient tool evaluate quality reliability of photodetectors, overall performance evaluation based on 1/f noise physical model is made build relationship between photoresponse...
Seed crystals are the prerequisite for growth of high quality and large size aluminum nitride (AlN) single crystal boules. The physical vapor transport (PVT) method is adopted to grow AlN seed crystal. However, this not available in nature. Herein, temperature field distribution PVT furnace was simulated using numerical analysis obtain free-standing large-size seeds. theoretical studies indicate that crucible related height. According theory dynamics surface dynamics, optimal thermal...
Different from the usual full counting statistics theoretical work that focuses on higher order cumulants computation by using cumulant generating function in electrical structures, Monte Carlo simulation of single-barrier structure is performed to obtain time series for two types widely applicable exclusion models, counter-flows model, and tunnel model. With high-order spectrum analysis Matlab, validation methods shown through extracted first four series, which are agreement with those...
In order to explore how extract more transport information from current fluctuation, a theoretical extraction scheme is presented in single barrier structure based on exclusion models, which include counter-flows model and tunnel model. The first four cumulants of these two models are computed structure, their characteristics obtained. A with the help three devised check process follow model, or neither them. Time series generated by Monte Carlo techniques adopted validate abstraction...
The paper reports a surface micro-machined relative humidity senor base on silicon epitaxial process. sensitive structure was fabricated by single crystal layer so that excellent mechanical and electronic performances of the device were achieved. To optimize sensor, an FEM method used to evaluate responses structures. A readout circuit test system designed sensor. According results sensitivity hysteresis sensor is 2mV/%RH 3%RH respectively. response time 65s.
A two-channel demultiplexer with channel spacing 1nm and the bandwidth around is demonstrated. The device established based on cascaded holographic filters. Each filter addresses a channel. by constructing single volume gating in LiNbO<sub>3</sub> crystal it drops light from specific DWDM (wavelengths of ~1550nm) 90-degree geometry. Volume gratings photorefractive material have been applied to devices systems owing narrow spectral selectivity. However, when numbers hologram increased, we...
The development of CubeSat and more frequent launch chances sounding rockets are a total game changer to the space program, it allows us build instruments be achievable affordable. Therefore, gives good opportunity small cosmic ray detector which has capabilities measure flux, direction, even energy rays at height above limitation balloon experiments, may open new door for building constellation detectors study physics. Compact Scintillator Array Detector (ComSAD) is dedicated rocket mission...
