Osteosarcoma is one of the most common primary bone tumors in children and adolescents, typically presenting with poor prognosis. Recent studies have found that TSSC3 had a potential capability in suppressing the tumor development in osteosarcoma. Our purpose was to explore the role of TSSC3 in the clinical outcome of osteosarcoma patients. Firstly, we detected the expression of TSSC3 at mRNA level...
A constant current control technique for a primary-side control system is proposed to realise high precision output current regulation. With the novel ring detect and demagnetisation portion control technique, the ending time of demagnetisation can be accurately determined and the portion of demagnetisation in a switching period remains precisely the same. The simulation results show that with this...
As the density of chip package increases, the thermal layout optimization of stacked chips has become more and more important. The thermal layout optimization of stacked chips is studied in this paper. Firstly, a hybrid algorithm of simulated annealing and particle swarm (SA-PSO) is proposed for thermal layout optimization. Secondly, the fitness function is obtained based on thermal superposition...
A quick checking algorithm is proposed in order to reduce the checking time of the design of the high-density circuits and improve the checking efficiency. This algorithm uses the theory of divide-and-conquer and combines the rules of geometrical shapes, and also optimizes the division of graphic elements and the comparison of graphic spacing. The quick checking algorithm proposed is superior to the...
