Damage of the normal tissue is a serious concenrn in cancer treatment. Hyperthermia by laserhas been considered as a safe cancer treatments methods with lower harmful effects on normaltissues. Using nanoparticles in cancer treatment has improved laser therapy, which is based ona selective cell targeting method to localize cell damages. Metallic nanoparticles such as gold,silver, and copper have...

The nervous system has an important and vital role in the human body, but unfortunately the repairment of damaged nervous tissue is very slowly. For a long time, the scientists have been involved in finding ways to speed up this process. Radiation of low power He-Ne laser has been suggested to as a way to improve this issue. In this study, 20 rats were divided randomly into control and case gro...

there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...
