Genome-wide association studies (GWAS) have reported a number of loci harboring common variants that influence risk of colorectal cancer (CRC) in European descent. But all the SNPs identified explained a small fraction of total heritability. To identify more genetic factors that modify the risk of CRC, especially Chinese Han specific, we conducted a(More)
Cooperative driving for vehicle platoon is one of the crucial application and demonstration in the field of Intelligent Vehicle-Highway Systems (IVHS). It is very important to use both hybrid dynamical system and hardware-in-the-loop simulation (HILS) to study cooperative vehicle platoon system. In the paper, different cooperative states of vehicle platoon(More)
A stereo obstacle detection method based on images symmetrical move and cell partition is presented in this paper. This algorithm gets each cell's optimum offset by calculating the minimum non-similarity of cell, and merges Cell of Interests (COIs) to calculate obstacles in the most probably obstacle regions, and gives information of these obstacles. The(More)
Arrayed genetic screens mediated by the CRISPR/Cas9 technology with single guide RNA (sgRNA) libraries demand a high-throughput platform capable of transfecting diverse cell types at a high efficiency in a genome-wide scale for detection and analysis of sophisticated cellular phenotypes. Here we developed a high-throughput in situ cell electroporation(More)
The ability to perform long-range pedestrian detection is essential for autonomous vehicles. However, for 3-D LIDAR, an object's point cloud becomes sparse when it is away, directly affecting its detection as a result. In this paper, a novel density enhancement method is proposed to improve the quality of a sparse point cloud. The input of the method is an(More)
Dielectrophoresis (DEP) can be used to noninvasively measure the dielectric state of the cell, and this data can be used to monitor cell health or apoptosis. In this study, we followed events associated with cytosine arabinoside (Ara-C)-induced apoptosis in NB4 cells using DEP analysis. Our data showed that the membrane capacitance of NB4 cells decreases(More)
In order to obtain obstacle information in the cross-county environment for an unmanned ground vehicle (UGV), AK-means clustering algorithm is applied in four-layer laser radar data mining in this paper. The result of clustering serves as candidate obstacles. To overcome the false clustering due to vibration of UGV, weighted Euclidean distance is used to(More)
This paper proposes a real-time traveling path tracking algorithm for intelligent vehicle. Two encoders are installed on the left and right wheels to measure the rolling distances of the wheels. A virtual coordinate system fixed to the ground is constructed. The calculating algorithm of vehicle position and heading angle in the virtual coordinate system(More)
