Parametric simulation models are developed for structural analysis of voting behaviors in public referendum. By decomposing the residents into eight groups, a mechanism is established to construct transition probability matrices defined on three states (0: Undecided; 1: YES; 2: NO) where individuals in one group have a common transition probability matrix but such matrices differ across different groups, thereby capturing behavioral patterns of the residents in forming their individual opinions toward the voting date. The underlying parameter values are identified in such a way that the voting results of eight real cases in Japan can be reproduced. The validity is tested through a mock public referendum. The parametric simulation approach proposed in this paper enables one to devise a strategy concerning how to transform the formation of the eight residential groups so as to achieve a target voting result.

Generation of iPS cells from mouse embryonic fibroblasts (MEF) was achieved using a BacMam transduction system containing a polycistronic plasmid expression vector for coincident and optimized expression of four defined reprogramming transcription factors. The sequences for Oct4, Klf4, Sox2 and c-Myc, were cloned as a fusion gene (OKSM) in a single open reading frame (ORF) via self-cleaving 2A peptides and expressed under the control of the CAG promoter. The transduction efficiency of primary MEF cells with BacMam particles carrying CAG-directed Venus reporter gene is 64-98 %. After three successive transductions (at intervals of 3 days) of MEF cells with BacMam particles carrying a OKSM or OSKM cassette, the iPS cell colonies are observed in 15-24 days. A single transduction of MEF cells is also effective in generating sufficiently reprogrammed iPS cell lines. The iPS cell lines from colonies picked were positively stained by Nanog, SSEA-1 immunofluorescence and alkaline phosphatase substrate markers. The advantage of using the EOS-S(4+)-EmGFP reporter to identify sufficiently reprogrammed iPS cell lines is discussed by representing experimental results obtained with electroporated plasmids, such as a mixture of 2 tandem OS and KM plasmids and a polycistronic OKSM expression plasmid.

周波数ホッピングは,フェージングによるバースト誤りをランダム化し誤り訂正効果を高める手段として効果的である.本論文では,ディジタル信号処理による周波数変換法を適用して,高速切換えを実現した周波数ホッピング送受信機の構成を述べている.まず,周波数ホッピング変調信号の生成と周波数変換フィルタを用いたホッピング信号の受信についてそれらの原理を述べる.次に,試作した96周波間(12.288MHz帯域幅)をホッピング可能な1.5GHz帯送受信機の構成(128kbit/s,差動符号化π/4シフトQPSK変調,遅延検波)について述べる.送信側(受信側)の周波数切換え時間はそれぞれ2(32)μsであり,約75μsでホッピング信号の周波数変換,検波が行われることを確認している.最後に,フェージング環境下における周波数ホッピングと誤り訂正の適用効果について実験的に評価している.本提案の方法は分周器と位相同期ループで構成される従来の周波数シンセサイザの代わりに固定周波数発振器を用いるので周波数切換えを高速にできるほか,ベースバンド処理を用いているのでLSI化に向いており,無線機の小型,低消費電力化に適している.
