Serine proteases play an important role in inflammation via PARs. However, little is known of expression levels of PARs on monocytes of allergic patients, and influence of serine proteases and PARs on TNF-α secretion from monocytes. Using quantitative real-time PCR (qPCR) and flowcytometry techniques, we observed that the expression level of PAR-2 in(More)
In this paper, a thresholding technique based on two-dimensional inter-class cross entropy and chaos optimization algorithm (COA) is presented. Firstly, adopt the cross entropy approach to describe the difference in pixel information between the object and the background in a two-dimensional histogram and to use maximum inter-class separation degree. Then(More)
In this paper, we present a collaborated architecture using microcontroller, stepping motor and physiological database to obtain the stress measurement of the quizzee. We implement an ergometric equipment for the purpose of iatrical experimentations. This equipment mainly consists of three components: embedded controller, integrator and background database.(More)
Social networks have been widely used, providing people with great convenience but also yielding potential risk of privacy disclosure. To prevent attacks based on background information or query that may expose users' privacy, we propose a method to achieve k-anonymization for network graphs. The concept of similarity matrix and that of the distance between(More)
