Dr. Alim Louis Benabid is a world-renowned French neurosurgeon who has had a global impact on the development of deep brain stimulation （DBS） for Parkinson＇s disease （PD） and other movement disorders. Dr. Benabid was awarded the 2014 Albert Lasker Award in Clinical Medicine and the 2015 Breakthrough Price. DBS, which delivers constant stimulation to small targets in the brain, is currently the most effective neurosurgical procedure for restoring patients＇ motor function. Since marketing approval for the use of DBS as a PD treatment was granted in Europe in 1998, DBS has been administered to over 150,000 patients, and it has become a standard treatment worldwide.

Based on the current news via Thomson Reuters "700 new regional journals in the world have been added to Web of Science since 2007",we conducted an investigation to find out that 43(6.1%) Chinese journals(including 6 journals from Hong Kong region) are included. The results also show that up to now a total of about 153 Chinese journals(114 from china Mainland,11 from Hong Kong and 28 from Taiwan) have been included by SCI and SSCI & AHCI.

The purpose of this study is to compare the part-load performance of a lean burn catalytic combustion gas turbine (LBCCGT) system in three different control modes: varying fuel, bleeding off the fuel mixture flow after the compressor and varying rotational speed. The conversions of methane species for chemical process are considered. A 1D heterogeneous plug flow model was utilized to analyze the system performance. The actual turbomachinery components were designed and predicted performance maps were applied to system performance research. The part-load characteristics under three control strategies were numerically investigated. The main results show that: the combustor inlet temperature is a significant factor that can significantly affect the part-load characteristics of the LBCCGT system; the rotational speed control mode can provide the best performance characteristics for part-load operations; the operation range of the bleed off mode is narrower than that of the speed control mode and wider than that of the fuel only mode; with reduced power, methane does not achieve full conversion over the reactor at the fuel only control mode, which will not warrant stable operation of the turbine system; the thermal efficiency of the LBCCGT system at fuel only control strategy is higher than that at bleed off control strategy within the operation range.

At present, one of the most important demands in the world is energy. And improvement of technology and management can increase energy efficiency [1]. Compared with coal and oil, electricity is a kind of clean and efficient secondary energy. The development of the electric power science is essential for the human world and its new results are also remarkable. A modem power system has a very complex control structure, and is generally composed of hundreds of thousands of components. Consequently, it is very difficult and arduous to control and manage a modem power system to make it reliably and securely provide high quality yet economic power supply.

Materials science is an interdisciplinary field applying the properties of matter to various areas of science and engineering. This scientific field investigates the relationship between the structure of materials at atomic or molecular scales and their macroscopic properties. It incorporates elements of applied physics and chemistry. With significant media attention focused on nanoscience and nanotechnology in recent years, materials science has been propelled to the forefront at many universities. Materials science encompasses various classes of materials, including electronic materials, functional ceramics, magnesium, material and processes for flat-panel displays, eco/environmental materials, sustainable energy materials, transportation materials, electronic packaging materials, etc.
