胎盤由来間葉系幹細胞の胎盤機能検査法としての役割に関する研究
No full textThe cellular and molecular mechanisms responsible for pregnancy-related disorders remain unclear. We investigated the feasibility of using placenta-derived mesenchymal stem cells (MSCs) as a tool to study such pregnancy-related disorders. We isolated and expanded adequate numbers of cells with characteristic features of MSCs from the chorionic plate (CP-MSCs), chorionic villi (CV-MSCs), and decidua basalis (DB-MSCs) of human term placental tissues. All placenta-derived MSCs expressed pregnancy-associated C14MC microRNA (miRNA) (miR-323-3p). Interestingly, the placenta-specific C19MC
miRNAs (miR-518b and miR517a) were clearly expressed in CP-MSCs and CV-MSCs of foetal origin, but were barely expressed in DB-MSCs of maternal origin. Furthermore, expression levels of placenta-specific C19MC miRNAs in CV-MSCs remained stable during the ex vivo expansion process and across different pregnancy phases (first trimester versus third trimester). High-efficiency siRNA transfection was confirmed in twice-passaged CV-MSCs with
little toxicity, and microarray analysis was used to screen for miR-518b target genes. Placenta-derived MSCs, especially CV-MSCs, are a potential tool for investigating the role of placental miRNAs in pregnancy-related disorders.長崎大学学位論文 学位記番号:博(医歯薬)甲第1006号 学位授与年月日:平成30年3月20日Author: Naoki Fuchi, Kiyonori Miura, Hanako Doi, Tao-Sheng Li & Hideaki MasuzakiCitation: Scientific Reports, 7, 46220; 201
Ambiguity Avoidance as Contrast Preservation: Case and Word Order Freezing in Japanese
No full textMuch recent work in phonology is concerned with evaluating contrasts among sets of forms (e.g. Flemming 1995, 1996; Ito and Mester 2003; Lubowicz 2003; Padgett 2003, 2004). This paper extends contrast preservation to syntax, where it can be used to explain anti-ambiguity phenomena. One such syntactic phenomenon is found in Japanese. Scrambling is generally tolerated in Japanese; however, when a subject and an object are morphologically identical (i.e. not distinguished by case morphology), scrambling is blocked. If scrambling were allowed in such a sentence, ambiguity would arise as to the subject of the sentence: 'Taroo-ga Hanako-ga kowai' could be the surface form of either an unscrambled structure 'Taroo-ga Hanako-ga kowai' (Taroo is afraid of Hanako) or a scrambled structure *'Taroo-ga(i) Hanako-ga t(i) kowai' (Hanako is afraid of Taroo). The ungrammaticality of the latter scrambled structure prevents subject-related ambiguity. I argue that this word order freezing (which occurs in German, Hindi, and Korean as well as Japanese: Lee 2001) is motivated by a PF constraint which demands contrast between forms with different subjects.The definitive version of this paper was published in University of Masschusetts Occational Papers in Linguistics 32: Papers in optimality theory III (2007) and is available at http://glsa.hypermart.net

A Kabuki Pose in Sculptures of Auguste Rodin = Egy kabukipóz Rodin szobraiban
No full textHanako (Ōta Hisa, 1868–1945) egy kis japán színitársulat jelentéktelen színésznője volt egészen addig, amíg az ismert táncos, Loïe Fuller fel nem fedezte. Miután Fuller látta Hanako haláljelenetét, úgy döntött, hogy az impresszáriója lesz. Ezt követően Fuller nemcsak megszervezte Hanako európai turnéját, hanem japán stílusú darabokat is írt a számára, amelyek kivétel nélkül a főhős kegyetlen, de rendkívül realisztikus haláljelenetével végződtek. Hanako a Marseille-i Gyarmati Kiállításon, 1906-ban találkozott Auguste Rodinnel. A szobrászt elbűvölte Hanako előadása, és megpróbálta kifaragni a „halál arcát”, amely a haláljelenetekben látható. Ez a különleges arckifejezés nagy valószínűséggel egy nirami, amely a kabukiszínház mie pózainak egyike. Rodin számos kisplasztikát készített különböző anyagokból, melyekben megkísérelte megörökíteni azt a pillanatot, amelyben Hanako meglátja a halált. Jelen tanulmány Hanako nyugati karrierjének ezt a rövid, de annál érdekesebb időszakát mutatja be, a színésznő Rodinnel való találkozását állítva középpontba. Történetük kiválóan illusztrálja, miként tettek erőfeszítéseket a japánok az 1900-as évek elején arra, hogy művészetüket a nyugati tekintetnek „megfelelővé” alakítsák, és hogy a Nyugat miként kereste ugyanekkor az „idegen” és „egzotikus” Keletről alkotott prekoncepcióinak igazolását
Underwater acoustic communication using Doppler-resilient orthogonal signal division multiplexing in a harbor environment
No full textUnderwater acoustic (UWA) channels are one of the historical mobile ultrawideband channels characterized by large delay and Doppler spreads, but reliable UWA communication remains challenging. Here we performed an initial demonstration of the Doppler-resilient orthogonal signal division multiplexing (D-OSDM) technique in an actual sea environment. D-OSDM spreads data symbols in both time and frequency with guardbands to exploit the time and frequency diversity of UWA channels. The experiment was performed in a challenging scenario: the transmitter was fixed on a floating pier, and the receiver was mounted on a moving remote-controlled boat. The harbor UWA channel had a delay spread of 50 ms and a Doppler spread of up to 4.5 Hz, in the presence of additive Gaussian noise, and the combination of two Rayleigh fading models (a two-path model without Doppler spread and a multi-path model with Doppler spread) was able to successfully model the actual environment. Our results also confirmed that a UWA communication link using D-OSDM will deliver excellent reliability even for a harbor UWA channel with a mobile receiver; D-OSDM achieves better communication quality compared to other communication schemes in both simulations and experiments.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Signal Processing System
Underwater Acoustic Communication Using Multiple-Input-Multiple-Output Doppler-Resilient Orthogonal Signal Division Multiplexing
No full textIn this paper, we propose a novel underwater acoustic (UWA) communication scheme that achieves energy and spectrum efficiency simultaneously by combining Doppler-resilient orthogonal signal division multiplexing (D-OSDM) and multiple-input-multiple-output (MIMO) signaling. We present both the transmitter processing and the receiver processing for MIMO D-OSDM. We evaluate the performance of MIMO D-OSDM in simulations with a large intersymbol interference of 25 symbols and a Doppler spread with a maximum Doppler shift of 8 Hz. In addition, the sea trial is performed in Suruga Bay, where the receiver is mounted on a barge and a research vessel with the transmitter makes round trips along a line with a speed of 4 kn. In the experiments, we obtain an intersymbol interference of 3.6-29.7 symbols and a Doppler spread of several Hertz (leading to a spread of over two to three subcarrier spacings). The simulation results suggest that MIMO D-OSDM has an advantage over normal D-OSDM, Doppler-resilient MIMO orthogonal frequency division multiplexing (MIMO D-OFDM), and classical OFDM with MIMO signaling (MIMO OFDM) - MIMO D-OSDM achieves better bit error rate performance than the benchmarks. The sea trial results also support the advantage of MIMO D-OSDM - it achieves a coded block error rate of 3.2% while normal D-OSDM and MIMO D-OFDM achieve a coded block error rate of 9.7% and 9.3%, respectively. We conclude that MIMO D-OSDM can become a viable technique that achieves reliable and effective UWA communication.

We present both the transmitter and receiver processing for MIMO D-OSDM. We evaluate the performance of MIMO D-OSDM in simulations with a large inter-symbol interference (60 symbols) and Doppler spread (maximum Doppler shift of 15 Hz). The simulation results show that MIMO D-OSDM achieves almost the same energy efficiency as normal D-OSDM while doubling the spectrum efficiency. We conclude that MIMO D-OSDM can become a viable technique that achieves reliable and effective UWA communication.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Signal Processing System
