We report the finding of kiloparsec (kpc)-scale radio structures in three radio-loud narrow-line Seyfert 1 (NLS1) galaxies from the Faint Images of the Radio Sky at Twenty-centimeters of the Very Large Array, which increases the number of known radio-loud NLS1s with kpc-scale structures to six, including two γ-ray-emitting NLS1s (PMN J0948+0022 and 1H 0323+342) detected by the Fermi Gamma-ray Space Telescope. The detection rate of extended radio emissions in NLS1s is lower than that in broad-line active galactic nuclei (AGNs) with a statistical significance. We found both core-dominated (blazar-like) and lobe-dominated (radio-galaxy-like) radio structures in these six NLS1s, which can be understood in the framework of the unified scheme of radio-loud AGNs that considers radio galaxies as non-beamed parent populations of blazars. Five of the six NLS1s have (1) extended radio luminosities suggesting jet kinetic powers of gsim 1044 erg s–1, which is sufficient to make jets escape from hosts' dense environments; (2) black holes of gsim 107 M ☉, which can generate the necessary jet powers from near-Eddington mass accretion; and (3) two-sided radio structures at kpc scales, requiring expansion rates of ~0.01c-0.3c and kinematic ages of gsim 107 years. On the other hand, most typical NLS1s would be driven by black holes of lsim 107 M ☉ in a limited lifetime of ~107 years. Hence, the kpc-scale radio structures may originate in a small window of opportunity during the final stage of the NLS1 phase just before growing into broad-line AGNs.

統計解析を行う際,得られたデータの中に外れ値が含まれることが多々ある.外れ値は少量であっても解析結果に大きく影響を与えることがあるため,従来から外れ値を含むデータに対する統計解析手法が数多く研究されている.従来,Boxらにより線形回帰モデルに対し混合分布を用いて外れ値の発生をモデル化する研究が行われている.同様のモデルに対し様々な研究が行われているが,いずれも外れ値の検出やパラメータの推定を目的としている.そこで本研究では,外れ値データの発生を含む回帰モデルに対する予測法について扱う.まず,このモデルに対しベイズ基準のもとで最適な予測法を示す.しかし,この方法はデータ数に対し指数的に計算量が増大してしまう.そこで,EMアルゴリズムを用いて計算量を削減した近似アルゴリズムを提案し,シミュレーションにより有効性を検証する.Outliers are often included in statistical data. A statistical analysis result is influenced from outliers. Therefore, there are many researches for a statistical analysis of data with outliers. Box modeled outliers using mixture distribution. There are many researches that aim parameter estimation or outlier detection about this model. In this paper, we treat prediction problem about this model. First, we present an optimal prediction method with reference to the Bayes criterion in this model. The computational complexity of this method grows exponentially with data size. Next, we propose an approximation algorithm reducing the computational complexity using EM algorithm, and evaluate this algorithm through some simulations.

In electric motor coaches, when the adhesion force coefficient between rail and driving wheel decreases suddenly, the electric motor coach has slip phenomena. We have already proposed the anti-slip control system based on ordinary disturbance observer. In order to realize the more stable anti-slip readhesion control in case of large variation of adhesion force coefficient, this paper proposes a new anti-slip readhesion control based on first order disturbance observer and new torque function. In the numerical simulation results in this paper, the proposed anti-slip readhesion control well regulates the driving wheel torque of electric motor coach stably.

This is a second story about Masu Gate, a "modern" Japanese woman who came of age and grew up to be a professional self-liberated woman in the Taisho Democracy period of Japan. The first story about her, presented in The Otsuma Journal of Comparative Culture, Spring 2006, depicted her "modern girl" life as an apprentice novelist / literary critic and the Yomiuri Newspaper's junior reporter. This second story describes Masu's highest stage of prosperity, which may well be characterized as professional and international, gaining her professional and secular fame as a Western-fashion dressmaker, "internationally" married to an American professor of a distinguished college in Tokyo.

This paper intends to portray a specific, so-called modern girl who was born in downtown Tokyo in the last decade of the Meiji era, grew up in the midst of the Taisho democracy period, became a well-known Western-style dressmaker with her training in the U.S. and with her American husband as well, and, then, survived the succeeding years of wars in the early Showa period, undergoing an unavoidable divorce with her pacifist American husband. "The modern girl," says Barbara Sato, "may best be understood as a phantasm rather than a social reality. Nevertheless, that phantasm was a marked feature of an urban society in flux, a powerful symbol of Taisho modernity." (p.49) Admitting that Sato's observation of the modern girl as a social phantasm is correct, the author of this paper still believes it is meaningful to present an "authentic" modern girl. The particular modern girl to be discussed henceforward, with the Japanese maiden name of Masu Hirai and the post-marital name of Masu Gate after "internationally" marrying Paul S. Gate, seems to have sincerely pursued to live a real life of modernity, to live as a professional woman independent both psychologically and economically, despite incessant harassments by traditionally-minded men and women in pre-modern Japan.

The purpose of this research is to develop a new technique for the turbulent drag reduction as the passive control. The pressure loss of three kinds of seal fur (Ribbon, Spotted and Harp seals) and an electret nonwoven fabric surfaces was measured in the channel flow using the water and glycerol-water (40 wt%). The data was compared with those of smooth and riblet surface. The drag reduction could be obtained for all kinds of seal fur surfaces; it was estimated to be 11.5 % on ribbon seal, 9.5 % on spotted seal and 3.5 % on harp seal for glycerol-water, while the drag reduction was not achieved for the electret nonwoven fabric surface.

2000年の「児童虐待の防止等に関する法律」の成立を契機に,わが国でも小児虐待に対する社会的関心が高まってきた.その中で,最も致命的で予後に大きく影響するのが,頭部外傷である.Shaken baby syndrome(SBS:揺さぶられっ子症候群)という言葉が有名になり,虐待による頭部外傷の総称として使われることもあるが,正しくは,non-accidenntal tramatic brain injury(nonaccidental TBI),あるいはinflicted traumatic brain injury(ITBI)である.すなわち,虐待による頭部外傷の受傷機転は,shaken(揺さぶり)だけでなく,直達衝撃(叩く,落とす,投げる),やそれらが複合したものと考えられている.虐待の診断には,打撲痕・熱傷・骨折など全身チェックに加え,頭部MRI検査は有用であり,眼底検査は必須である.半球間裂から円蓋部にかけて,あるいは小脳テントに沿って存在する急性硬膜下出血が最も多くみられる.ITBIの死亡率は15〜38%で,生存者の30〜50%が障害を持ち,正常に回復する率は30%といわれ,その転帰は非常に悪い.自宅に戻った時に繰り返される率は31〜43%である.従来から中村の血腫1型として報告されてきた家庭内の軽微な外傷による網膜出血を伴う急性硬膜下血腫が,虐待の範疇に入るのか,虐待とは別のclinical entityとして考えるのか,いまだ議論のあるところである.
