ANALYSIS OF LASER INTENSITY NOISE IN ELECTRO-OPTIC SENSOR SYSTEM USING POLARIZATION SIMULATOR AND FREQUENCY DEPENDENT NOISE MODEL
Get PDFThe EO sensor system is a non-contact electric field measurement system using laser light and an EO crystal. The sensor can be used to measure voltage of the organic photovoltaics. The laser intensity noise is generated by laser diode. The laser intensity noise depends on frequency. The laser intensity noise is modulated by the signal. We analyze the effect of modulation of laser intensity noise on the EO sensor using a polarization simulator and a frequency-dependent noise model. The phase difference of modulated laser intensity noise component is π rad and amplified after differential detection. We confirm the reduction of the relative intensity noise is necessary to improve the signal-to-noise ratio of the EO sensor using differential detection
THE ROLE OF FIS NUCLEOID-ASSOCIATED PROTEIN ON TRANSITION FROM LAG PHASE TO LOG PHASE OF ESCHERICHIA COLI
Get PDFThe growth of E. coli consists of three phases: lag phase, log phase, and stationary phase. When stationary phase cell is transferred to a fresh medium, it is able to start to grow as similar growth process. E. coli has six major nucleoide-associated proteins (NAPs), Dps, Fis, H-NS, HU, IHF, and StpA, and their intracellular level changes with the growth phases. The detailed roles of these NAPs, however, remain unclear in lag phase. In this study, I showed the role of Fis in the restart of E. coli growth. I found that the level of Fis was maximal immediately before first cell division but the level of fis mRNA was constantly high in all phases. In addition, Western Blotting showed the significant detected level of Fis in ΔclpAXP at stationary phase. Fis is known to increase mRNAs of total 53 tRNA genes. Luciferase reporter assay indicated that thrW and pheU promoter were decreased whereas pheV and proK promoter were increased in Δfis. Taken these results together, the intracellular level of Fis is mainly regulated by Clp protease and reach maximum immediately before log phase, which induces tRNA gene promoters to accelerate translation for proliferation
Ryohin Keikaku’s Indigenization Strategy and Individual Store Management : Case Studies of Naoetsu, Niigata Prefecture and Hakodate, Hokkaido
Get PDFIt has been argued that Japan’s aging and declining population are draining local economies. However, the Japanese government has been unable to provide a clear solution, and local governments have likewise been unable to find a solution to the problem amid dwindling financial resources. Moreover, major companies headquartered in the capital have begun to withdraw from regions with shrinking markets in order to improve their operational efficiency. To remedy this situation, Ryohin Keikaku has partnered with local governments and local residents to introduce indigenization strategies and individual store management. By using case study approaches, this paper explores how the company manages its stores as essential community centers that involve local consumers. In particular, based on extensive interviews and field research, this report examines how community managers in Naoetsu, Niigata and Hakodate, Hokkaido overcame difficulties, integrated with residents, and built indispensable local brands

Sport-life balance in college athletes linked to their well-being
Get PDF本研究の目的は，大学生アスリートにおけるスポーツ・ライフ・バランスの現状，および理想と現実のギャップを検証することであった。さらに，初年次学生である1年生と2－4年生の間でスポーツ・ライフ・バランスの指標を比較したうえで，理想と現実のギャップとウェルビーイングとの関連も検討した。大学生アスリート149名のデータを分析したところ，（1）スポーツ・ライフ・バランスは，時間的なバランスも，精神的なバランスも，やや競技生活に偏っていた。（2）学年差を検討したところ，精神的なバランスは，2年生以上の方が競技の比重が大きかった。（3）時間的なバランス・精神的なバランスともに，バランスの現状と理想と現実のギャップが，ウェルビーイングと部分的に関連していた
