Purpose: to investigate a genetic algorithm approach to automatic treatment planning. Methods: A Python script based on genetic algorithm (GA) was implemented for VMAt treatment planning of prostate tumor. the script was implemented in RayStation treatment planning system using Python code. two different clinical prescriptions were considered: 78 Gy prescribed to planning target volume in 39 fractions (GROUP 1) and simultaneous integrated boost (70.2 Gy to prostate bed and 61.1 Gy to seminal vesicles) in 26 fractions (GROUP 2). the script.a.tomatically optimizes doses to PtV and OARs according to GA. A comparison with corresponding plans created with Monaco tPS (M) and Auto-Planning module of Pinnacle3 (AP) was carried out. the plans were evaluated with a total score (tS) of PlanIQ soft.a.e in terms of target coverage and sparing of OARs as well as clinical score (CS) performed by a Radiation Oncologist. Results: In GROUP 1, mean value of tS were 150.6 ± 30.7, 146.3 ± 36.1 and 137.4 ± 35.7 for AP, GA and M respectively. For GROUP 2, mean value for tS were 163.5 ± 16.8, 163.4 ± 24.7 and 162.9 ± 16.6 for AP, GA and M respectively with no significance differences. In terms of CS, the highest value has been attributed to GA in four patients out of five for both GROUP 1 and 2. Conclusions: Genetic approach is practicable for prostate VMAt plan generation and studies are underway in other anatomical sites such as Head and Neck and Rectum.

锆和钽基氧气还原反应催化剂的简易合成(英文)

催化学报 2015年第4期36卷 484-489页

Cathode catalysts for direct.a.cohol fuel cells(DAFCs) must have high catalytic activity for the oxy-gen reduction reaction(ORR), low cost, and high tolerance to the presence of met.a.ol or et.a.ol. Pt is the benchmark catalyst for this application owing to its excellent electrocatalytic activity, but its high cost.a.d low tolerance to the organic fuel permeating through the membrane have hindered the commercialization of DAFCs. Herein we present.a.facile synthesis route to obtain organic fuel-tolerant Zr- and ta-based catalysts supported on carbon. this method consists of a simple precipitation of metal precursors followed by a heat treatment. X-ray diffraction analyses confirmed t.a. the obtained samples were crystalline ZrO 2-x and Na2ta8O21-x having crystallite sizes of 26 and 32 nm, respectively. the thermal treatment effectively increased the activity of the catalysts to-wards the ORR, although further optimization is necessary. Both catalysts exhibited a high tolerance to the presence of met.a.ol with only a moderate reduction in ORR activity even at high met.a.ol concent.a.ion(0.5 mol/L).
