Microfluidic devices are important for the single cell analysis such as cell mechanical and electrical characterization. Single cell characterization could be related to many significant applications including early disease diagnosis. However to perform the single cell manipulation, firstly a single cell have to be isolated and a platform for the cell manipulation have to be provided. One of the methods to trap a single cell is by using hydrodynamic trapping in the microfluidic channel. This study provides a finite element model for single cell trapping for a yeast cell model. The objectives of the simulations are to obtain the appropriate channels' geometry and optimized ratio of the fluid's inlet and suction flow rate to trap a single yeast cell. Trap channel was designed to trap a 5 mu m yeast cell with a suction hole placed in the end of the trap channel. Design geometry and ratio of fluid flow rates referring to the hydrodynamic concept were studied for the cell trapping model. The analysis was carried out using numerical solutions from the finite element ABAQUS-FEA software. Using the cell trapping model, a single yeast cell able to be trapped into the trap channel with optimized channel's suction hole's geometry and appropriate fluid's inlet and suction flow rate ratio.

"Preemptive Hadoop Jobs Scheduling Under a Deadline" by Li Liu, Yuan Zhou, Ming Liu, Guandong Xu, Xiwei Chen, Dangping Fan, Qianru Wang in the Proceedings of the internationalconference on Semantics, Knowledge and Grids, October 2012, pp. 72-79 MapReduce is a programming model developed for processing large amount of data with parallel and distributed algorithm on a cluster of computing nodes. It provides convenient programming interface distributing data intensive works in a cluster environment such as Hadoop. Preemption is an effective approach for MapReduce scheduler in avoiding the delay of high priority jobs while allowing the system to be shared by regular jobs. In this paper the problem of deadline constraint scheduling on a MapReduce model is addressed. We present a new preemption approach which considers the remaining execution time of the job being executed in making the decision of preemption. Computer simulation demonstrates that the proposed scheme reduces the job execution time and waiting time in the queue compared to the existing scheme.
