Acute lymphoblastic leukemia (ALL) is the most prevalent neoplasia among children, and drug resistance is still a major cause of chemotherapy failure in pediatric ALL. Prior research has shown that microRNAs (miRNAs) can play roles in such phenomenon, but detailed regulation mechanisms are far from completely understood. We utilized a semantic analysis approach and its MeSH term filtering mechanisms...
Discharge location is an important issue and technical guarantee for AC withstand voltage test which is the key test in the handover test of extra-high voltage (UHV) equipment. In order to ensure the smoothly processing of the equipment defect inspection as well as the elimination of hidden fault, the discharge location technique in AC withstand voltage test of 1100kV Gas insulated metal-enclosed...
With the rapid increasing of railway mileage, automatic railway intrusion detection by analyzing the video from train-mounted camera is becoming very meaningful. But there exits serious jitter in the video since the camera always vibrates with train when it is running, a video stabilization reprocessing procedure is the prerequisite before the intrusion detection analysis. To solve this question,...
This paper is dedicated to the “40 Years of Ocean Remote Sensing — a Session to Honor W. Alpers on the Occasion of his 80th Birthday”. In this paper, a list of Alpers' research contributions in understating the atmospheric gravity waves and oceanic internal waves are highlighted along with up-to-date research finding in these fields. On the atmospheric side, we presented the SAR observation of atmospheric...
The Category-4 typhoon Malakas moved along the continental shelf margin of the East China Sea from September 16 to 18, 2016. The typhoon-induced 2°C-3°C sea surface cooling and 0.8 mg/m3 Chlorophyll-a concentration change were observed by the geostationary satellite sensors carried by the Japanese Himawari 8 Advanced Himawari Imager (AHI) and the South Korean Geostationary Ocean Color Imager (GOCI)...
Early in the development of any field of inquiry, new and interesting phenomena are uncovered and appreciated. These may be of general scientific interest, but is it often many years before these initial observations mature to the point that they can be employed for practical applications. Dr. Werner Alpers is one of those unique individuals whose long productive career spans the evolution from research...
The spatiotemporal fluctuation of flying squid resources from July to November in 2009 to 2014 and its relationship with ocean environmental variables are analyzed with the GAM model in this study. The most suitable SST, SLA and Chla are 16–18°C, 0.5–4 cm and 0.25–0.3 mg/m3, respectively. The model results showed that the Month and the Latitude have greatest effect on the CPUE. The influence of environmental...
In recent years, both passive and active (i.e., Synthetic Aperture Radar or SAR) satellite remote sensing has proven to be valuable tools for mapping land cover. Most of the classification algorithms are based on image-intensity and they do not perform well in different coastal zone types, because these terrains have similar optical or radar backscattering signals. In this paper we propose a weighted...
The use of co-polarization (HH or VV) synthetic aperture radar (SAR) normalized radar cross section (NRCS) measurements to estimate winds speed has matured to an operational product. However, these wind speed retrievals have only been well validated for wind speeds less than 20 m/s and require some a priori estimated of the wind direction. At higher wind speeds, the radar cross section for co-polarization...
The cable acquisition and control system of the traditional greenhouse has many disadvantages such as complicated wiring, high cost and lack of accuracy and expansibility. In order to solve those problems, a greenhouse acquisition and control system based on ZigBee wireless sensor network (WSN) is designed in this paper. The ZigBee with temperature sensor DS18B20 and humidity sensor AM2301 is used...
Multiple object tracking has been modelled as minimum cost network flow (MCNF) optimization problem recently. It is one of the most popular tracking-by-detection algorithm. MCNF is particularly effective due to its simple model and optimal solutions. However, complex scenarios, such as noisy detections and multi-objective interactions, make it difficult to track multi-objects in consecutive frames...
Super-resolution (SR) algorithms for multiview videos aim at refining the low-resolution (LR) views using high-frequency detail information from adjacent high-resolution (HR) views. However, to refine a LR view, the state-of-the-art methods only exploit the spatial redundancy of a multiview video. To take full advantage of the spatial and temporal redundancy, a new spatiotemporal SR algorithm is proposed...
During the transmission of digital image, in view of the security problem, use 2-D discrete wavelet transform and chaos system to realize the image encryption and decryption. When the target image is encrypted, firstly, the ‘bior3.7’ wavelet is used for wavelet decomposition; and it can get the low and high frequency wavelet coefficients; then, the 1-D Logistic chaos sequence is used to reorder the...
Multi-target tracking under the condition of occlusions is one of the difficult and attractive field in video tracking. Multi-target tracking has been modelled as network flows (NF) optimization problem recently. It is one of the most popular tracking-by-detection (TBD) algorithm, which links individual detections into trajectories. NF method is particularly effective due to its simple model and optimal...
Ultra-high-frequency (UHF) technique for detecting partial discharge (PD) phenomenon is a useful method to avoid insulation accidents in gas insulated switchgear (GIS). However, the circumferential angle position of UHF Sensor in GIS has a great effect on the PD detection, which has not been investigated sufficiently. To deeply investigate the propagation characteristics of UHF signal and improve...
Super-resolution (SR) algorithms for video sequences with high resolution (HR) guide frames can provide outstanding performances. Non-local means (NLM) algorithm compares the similarity between a pixel and its neighbors. NLM replaces every pixel with a weighted average of its neighbors. The NLM based SR algorithm can super-resolve low resolution (LR) frames using the HR guide frames in the video sequence...
Due to the low spatial resolution of passive microwave sensors, the spatiotemporal heterogeneity of snow parameters may be the primary factor influencing the inversion accuracy. However, at present, continuous observations of snow parameters are rare due to the limited automation of snow monitoring equipment. In this study, a passive microwave pixel is selected as the experimental region, and detailed...
From the perspective of energy, solar cells are not only the devices to convert photon energy into electricity, but also the typical thermodynamic systems with heat generation and dissipation. Hence, optoelectronic and thermodynamic simulation showing profound light-matter interactions as well as multi-physical responses of photovoltaic devices play a significant role in solar cell designs. We perform...
Conventional photodetectors are mostly propelled by p-n junctions, where the detection wavelength is constrained by the bandgap of semiconductor material. Recently, a meta-linsulator-metal (MIM) configuration is demonstrated to be a promising candidate for the next generation photodetection due to its highly tunable operation wavelength, simple configuration, and possibly low cost. The MIM photodetector...
To overcome the real-time and robust problem of visual tracking, a visual tracking algorithm based on a fusion of multi cue and particle filter was proposed. Firstly, the integrating formula was transmuted on the framework of particle filter base on multi-cues which integrated multi-cues based on cues rather than feature points so that it could be used for parallel computing. Secondly, the EM algorithm...
