Numerical modeling and simulation of temperature distribution uncertainty subject to ferromagnetic thermoseeds hyperthermia

In the process of ferromagnetic thermoseeds mediated magnetic induction hyperthermia, the tempera- ture distribution in the tumor region is a key factor to determine the therapy effect. During the preoperative treatment planning, discrepancies of the treatment parameters may lead to the temperature distribution uncertainty within the target area. Inaccurate prediction of temperature distribution may induce the treatment failure; therefore, it would be significant to investigate the uncertainty of tissue temperature prediction caused by the disturbance of calculation parameters. In this paper, 3D temperature field and necrosis zone of tissues in ferromagnetic thermoseeds hyperthermia are simulated by the finite volume algorithm, and effects of parameter uncertainties on the temperature distribution are revealed. Results show that selecting appropriate magnetic field parameters for treatment is a priority to guarantee therapeutic effect. Thermoseed properties and blood perfusion rate are the obvious disturbing terms for temperature distribution, while the metabolic heat of bio-tissues can often be ignored within limits. Our investigation is of importance for guiding reasonable and optimal preoperative treatment planning.

区域PSEE系统发展动态研究——以宁夏回族自治区为例

运用层次分析法,构建了区域PSEE系统科学发展评价指标体系,并对宁夏PSEE系统1990-2006年的发展动态进行了定量评价.结果表明.2006年的科学发展指数为0.36,全面发展指数为0.46,协调发展指数为0.24,可持续发展指数为0.37,分剐比1990年提高了61%、50%和114%.依据评价等级标准,2006年科学发展指数为稍低等级,全面发展指教为中下等级,协调发展指数为较低等级,可持续发展指数为稍低等级,与发展目标还有很大的差距.据此,提出了快速发展新材料产业、加快发展县域经济、加强生态环境保护和建设等发展对策.     

Algorithms for degree-constrained Euclidean Steiner minimal tree

A new problem of degree-constrained Euclidean Steiner minimal tree is discussed, which is quite useful in several fields. Although it is slightly different from the traditional degree-constrained minimal spanning tree, it is also NP-hard. Two intelligent algorithms are proposed in an attempt to solve this difficult problem. Series of numerical examples are tested, which demonstrate that the algorithms also work well in practice.
