In this paper, a photo-modulated transistor based on the thin-film transistor structure was fabricated on the flexible substrate by spin-coating and magnetron sputtering. A novel hybrid material that composed of Cd Se quantum dots and reduced graphene oxide(RGO) fragment-decorated ZnO nanowires was synthesized to overcome the narrow optical sensitive waveband and enhance the photo-responsivity. Due to the enrichment of the interface and heterostructure by RGO fragments being utilized, the photo-responsivity of the transistor was improved to 2000 AW^(-1) and the photo-sensitive wavelength was extended from ultraviolet to visible. In addition, a positive back-gate voltage was employed to reduce the Schottky barrier width of RGO fragments and ZnO nanowires. As a result, the amount of carriers was increased by 10 folds via the modulation of back-gate voltage. With these inherent properties, such as integrated circuit capability and wide optical sensitive waveband, the transistor will manifest great potential in the future applications in photodetectors.

Following the Japanese Liberal Democratic Party＇s victory in the December 2012 election, some Japanese analysts pointed out that the new Abe/Aso Govemment would introduce rightist policies, and that as such it would be more difficult for China and Japan to improve their bilateral relations. As expected, in the past six months since its coming to power, the Abe cabinet has vigorously promoted so-called ＂Abe economics＂ and implemented a quantitative easing monetary policy that has caused a drastic depreciation of the Japanese Yen. In order to revise the ＂Constitution of Japan＂, in July 2013 it has been striving to win the election of the Senate. Externally, the new cabinet members have frequently visited foreign countries, implementing a diplomatic strategy of containing and countering China. One of its aims is to completely rid itself of the shackles of World War II and to try to reconstruct powerful military forces. The Diaoyu Islands issue has been used by the Abe cabinet to serve its domestic and foreign policy objectives,

The property of silicon micro-capacitive accelerometer is analyzed and discussed by establishing the model of the sensor,to lay a basis for optimization design of sensor system structure. Discussed issues include the static modeling and dynamic behavior of the two commonly used structures,i.e., double-cantilever supported and four-beam supported structures, and also the measurement range of these devices.

A recombinant fowlpox virus co-expressing Haemagglutinin (HA) and Neuraminidase (NA)named as rFPV-HA-NA was produced by HA and NA gene of A/Goose/Guangdong/3/96(H5N1)isolate of avian influenza virus recombined into the genome of fowlpox virus. In thisstudy, to evaluate its ability of protecting chickens against challenge with a lethaldose of highly pathogenic isolates of avian influenza virus, eight-week-old specific-pathogenic-free (SPF) chickens were vaccinated with recombinant virus or the wildtypefowlpox virus by wing-web puncture. After challenge 4 weeks with 10 LD50 highly pathogenicavian influenza virus H5N1 and H7N1 isolate, all chickens vaccinated with recombinantvirus were protected, while the chickens vaccinated with the wildtype fowlpox virus orunvaccinated controls experienced 100% mortality respectively following challenge. Thiscomplete protection was accompanied by the high levels of specific antibody response tothe respective components of the recombinant virus.
