Portable diagnostic devices have emerged as important tools in various biomedical applications since they can provide an effective solution for low-cost and rapid clinical diagnosis. In this paper, we present a micropore-based resistive cytometer for the detection and enumeration of biological cells. The proposed device was fabricated on a silicon wafer by a standard microelectromechanical system processing technology, which enables a mass production of the proposed chip. The working principle of this cytometer is based upon a bias potential modulated pulse, originating from the biological particle's physical blockage of the micropore. Polystyrene particles of different sizes (7, 10, and 16 μm) were used to test and calibrate the proposed device. A finite element simulation was developed to predict the bias potential modulated pulse (peak amplitude vs. pulse bandwidth), which can provide critical insight into the design of this microfluidic flow cytometer. Furthermore, HeLa cells (a type of tumor cell lines) spiked in a suspension of blood cells, including red blood cells and white blood cells, were used to assess the performance for detecting and counting tumor cells. The proposed microfluidic flow cytometer is able to provide a promising platform to address the current unmet need for point-of-care clinical diagnosis. © 2014 WILEY-VCH Verlag GmbH & Co.

Based on China AVS standard, this paper proposed a method of built-in video watermark technology. Authentication information was generated from I frame as the watermark, and is embedded into selected positions of later P-, B-frames. An algorithm was designed and introduced in this paper to verify the video modification status via abstracted watermark. Dependent on feature of credible encoding/decoding of AVS video, besides appropriate watermark robustness could be guaranteed; this method can minimize the watermark capacity and can reduce the impact on video, as well as detection sensitivity for video tampering of watermark algorithm could be guaranteed. The test results show that the technology proposed by this paper has almost zero effect on vision and encoding efficiency, while also can detect the position of the tampering precisely. © 2010 IEEE.

One of the core problems which cloud resources scheduling need to solve is the load balance. In the cloud resources scheduling process, if load changes suddenly, this may cause resources scheduling tilt. This paper takes real-time load parameters (CPU occupancy rate, memory occupancy rate, network bandwidth, the process occupancy rate, service response time) from the server cluster nodes as decision variables of resources scheduling model, and uses the improved adaptive genetic algorithm to search the optimal solution, in order to realize the load balancing scheduling of cloud resource, and make the each index change smoothly. The experimental result shows that, using the improved load balancing scheduling strategy to solve the problems of the load balancing scheduling of cloud resource, not only makes the each index of the system change smoothly, but also improves the performance of the system efficiently. © 2012 Binary Information Press.
