First clinical experience of the looped Inoue balloon technique for antegrade percutaneous balloon aortic valvuloplasty.
No full textBalloon aortic valvuloplasty (BAV) has played a limited role in the management of patients with severe aortic stenosis. However, BAV is being performed more frequently these days with the emergence of transcatheter aortic valve implantation (TAVI). We previously described a technique named "looped Inoue balloon technique" to simplify the antegrade transvenous BAV by making a loop in the left atrium using two stylets. We present a case in which the looped Inoue balloon technique was successfully applied. The patient was an 83-year-old woman with progressive dyspnea due to severe aortic stenosis. The aortic valve area was 0.39 cm(2) with a mean transvalvular gradient of 46 mmHg. The patient was deemed high risk for surgical aortic valve replacement or TAVI in view of the multiple comorbidities and frailty. Antegrade BAV using the looped Inoue balloon technique was performed. The procedure was successful without any complications. The post procedural aortic valve area increased to 1.15 cm(2) with a mean pressure gradient of 23 mmHg. This is the first report of clinical use of the looped Inoue balloon technique for antegrade BAV
Lecideoid lichens of Prince Olav Coast and Soya Coast, Enderby Land, East Antarctica
No full textFive species of lecideoid lichens belonging to three genera are reported as new to the flora of the Prince Olav Coast and the Soya Coast, Enderby Land, East Antarctica; they are Carbonea capsulata (DODGE & BAKER) HALE, Lecidea andersonii R. FILSON, Lecidea cancriformis DODGE & BAKER, Lecidea soyaensis M. INOUE and Lecidella siplei (DODGE & BAKER) M. INOUE. All are endemic to Antarctica. An examination was made of the collections from the region, which were collected mainly by the author under the project of the 27th Japanese Antarctic Research Expedition (JARE-27,during January 1986 and February 1987). The type and authentic specimens of possibly related species have been restudied. Lecidea soyaensis M. INOUE is new to science and Lecidella siplei (DODGE & BAKER) M. INOUE is proposed as a new combination. Taxonomic and chemical data as well as a key to the known taxa are provided
The Hobby of Electronic Circuit Engineering
No full textThis website (originally created in Japanese and translated into English using translation software) by a Japanese systems engineer, Seiichi Inoue, provides an extensive overview of electronic circuit engineering. Topics covered include: Basic knowledge of Electronic parts, Basic knowledge of Engineering Instruments, an Introduction of Engineering Method, and the Assembly Process. A variety of electronic circuits and their uses are provided, as well as a separate section on PIC electronic circuits. The language may be difficult to follow at times given the translation, but still a gem of a site for anyone wanting to build some circuits! Keep in mind that in some sections, the author notes that he is "describing while studying, there seems to be mistakes in the contents. Do at your own risk." For some further browsing, he includes sections on his other interests, such as 3D photography, java programming, CAD, Japanese customs and the Japanese language
Nickel-Catalyzed Electrophilic Amination of the Biphenylene C-C σ-Bond
No full textInoue T., Nishino S., Yasui K., et al. Nickel-Catalyzed Electrophilic Amination of the Biphenylene C-C σ-Bond. Organic Letters 26, 4268 (2024); https://doi.org/10.1021/acs.orglett.4c01226.A nickel-catalyzed three-component carboamination of the biphenylene C-C σ-bond has been developed. Arylboronates and hydroxylamine derivatives work as carbon nucleophiles and nitrogen electrophiles, respectively, and the corresponding difunctionalized ring-opening products are obtained in good yields. The arylboronate nucleophile can be replaced with B₂pin₂ (boron nucleophile) and H-Si(OMe)₃ (hydride nucleophile), thus allowing for the aminoboration and hydroamination of the biphenylene C-C σ-bond under similar nickel catalysis
The distribution of first-passage times and durations in FOREX and future markets
No full textPossible distributions are discussed for intertrade durations and first-passage processes in financial markets. The view-point of renewal theory is assumed. In order to represent market data with relatively long durations, two types of distributions are used, namely a distribution derived from the Mittag Leffler survival function and the Weibull distribution. For the Mittag-Leffler type distribution, the average waiting time (residual life time) is strongly dependent on the choice of a cut-off parameter tmax, whereas the results based on the Weibull distribution do not depend on such a cut-off. Therefore, a Weibull distribution is more convenient than a Mittag Leffler type if one wishes to evaluate relevant statistics such as average waiting time in financial markets with long durations. On the other hand, we find that the Gini index is rather independent of the cut-off parameter. Based on the above considerations, we propose a good candidate for describing the distribution of first-passage time in a market: The Weibull distribution with a power-law tail. This distribution compensates the gap between theoretical and empirical results more efficiently than a simple Weibull distribution. It should be stressed that a Weibull distribution with a power-law tail is more flexible than the Mittag Leffler distribution, which itself can be approximated by a Weibull distribution and a power-law. Indeed, the key point is that in the former case there is freedom of choice for the exponent of the power-law attached to the Weibull distribution, which can exceed 1 in order to reproduce decays faster than possible with a Mittag Leffler distribution. We also give a useful formula to determine an optimal crossover point minimizing the difference between the empirical average waiting time and the one predicted from renewal theory. Moreover, we discuss the limitation of our distributions by applying our distribution to the analysis of the BTP future and calculating the average waiting time. We find that our distribution is applicable as long as durations follow a Weibull law for short times and do not have too heavy a tail

Poet of Perpetuity and Stagnation: Inoue Yasushi\n―On the Resonance of Youth and Antiquity in Ikoku no Hoshi
No full textpdfInoue Yasushi was an author who has continuously written on the history of the West and the dialogue between Eastern and Western cultures. His literary world consists of genres such as historical novels, biographical novels, and prose poems, but each contains a storytelling structure. Ikoku no Hoshi (1984) likewise has its own form of storytelling. Recording his journey in his 70s along the Silk Road, from northern Siberia, the northern and southern roads of Tien Shan, and the Taklamakan Desert, to Pamir and Pakistan, following the path of Genjō Sanzō, and finally to Istanbul, Ikoku no Hoshi is a challenging work from late in his career. As can be seen from the titles “Gilgit Correspondence”, “Kaxgar Diary”, “Himalayan Moon”, “Letter from the Desert”, The town of Amurskaya”, “Crossing point on the Indus”, “Yumen Notebook”, “At the foot of India (Tenjiku), 1 and 2”, it is a truly grand prose poetry collection. Made up of correspondences, diaries, journals, and notebooks, it is not merely a collection of writings, but is designed to be a prose poem. The secret lies in the world of Inoue Yasushi’s dignified “prose meter”. Inside is hidden a deep and sacred philosophy-perpetuity and stagnation. Of course, the places, times, things, people, thoughts, and events he encountered act as devices for memory. Inoue Yasushi is not the kind of poet or writer who abandons a relation in order to focus on discussing himself. In Ikoku no Hoshi, he touches relentlessly on places he has been in life, experiences during wartime, and people he has met, drawing on memories of the past in order to speak to the deceased. At other times he brings his youth back from his memory to form a dialog with his present self or history of the distant past. It contains a vibrant textuality between his youth and history. This presentation looks at the infrequently examined structure and characterizations in Ikoku no Hoshi through Inoue Yasushi’s prose poems. In addition, through the many thoughts of lnoue Yasushi seen in the deceased author of The Star of Samarkand and his letters to numerous anonymous people, I will examine poet Inoue Yasushi’s philosophy of perpetuity and stagnation.conference pape
