Yarrowia lipolytica is the well-known oleaginous yeast able to accumulate amounts of lipids and a variety of high value products. The knowledge of its intracellular metabolites concentrations, which are directly linked to the sample preparation of corresponding intracellular metabolites, is of fundamental importance for the characterization of its metabolism. Therefore, in this study, we evaluated...
Coverage is a fundamental problem in Wireless Sensor Networks (WSNs). Existing studies on this topic focus on 2D ideal plane coverage and 3D full space coverage. The 3D surface of a targeted Field of Interest is complex in many real world applications; and yet, existing studies on coverage do not produce practical results. In this paper, we propose a new coverage model called surface coverage. In...
High error rate is critical to the wireless video transmission. Our paper tackles the problem of robust video streaming over error-prone channels. Basing on an autoresilient multiple-description coding method and a multi-path transmission strategy, further study is done on the computational complexity of rate-distortion optimization for video coding and transmission. A unitary-optimized operation...
To reduce the high frequency gate drive losses, a new resonant gate driver is developed for low voltage synchronous buck converter based on the topologies optimizations of three candidate resonant gate drivers in this paper. The new drive circuit can reduce gate drive losses significantly. The advantages of the proposed circuit include less sensitive to track inductance, no need for a bootstrapped...
A novel over-current protection method for LLC resonant converter has been proposed in this paper. This method is very attractive for its good current limit ability, especially under short circuit condition. Moreover, its current limit point range is easy to be optimized. Detailed theoretical analysis and optimization design considerations have been presented. An experimental prototype converter based...
