Invited paper to the Sixth International Quantum Electronics Conference, Kyoto, Japan, September 1970. T. Kobayasi and H. Inaba. Proceedings of IEEE., 58, 1568, (1970).""Author Institution: Research Institute of Electrical Communication, Tohoku UniversityThe usefulness of Raman spectroscopy, which is so far recognized as a complementary technique to infrared spectroscopy, can be extended to include various new fields which are unique to itself. The laser-Raman radar scheme detecting the Raman backscattered echoes has been and confirmed experimentally by the present , which is capable of measuring remotely the number density of molecular constituents as well as their species existing not only in the ordinary but also in the polluted atmosphere. This paper wishes to report the operational performance and the experimental results, so far obtained, of our laser-Raman radar as a completely single-ended system for the chemical analysis of the real atmosphere. An alternative method, which utilizes a frequency-tunable dye laser with high repetition rate of pulsed operation is also developed to investigate the resonance spectroscopic effects of a variety of molecules and atoms contained in the lower and upper atmosphere. These effects include the fluorescence and the resonance scatterings along with the resonance Raman scattering, and are expected to improve significantly the sensitivity and the range capability for the constituent analysis of our environmental air

This paper presents the measured result and their comparison of the Raman cross sections of various molecules present in the atmosphere such as relative to that of as a reference gas. We employed primarily a molecular nitrogen laser with 10mW average power at 3371 {\AA}, 20 kW peak power of 10 nsec duration and a repetition rate of 50 Hz. Recently, we have succeeded in the operation of transverse excitation atmospheric (TEA) nitrogen laser at 3371 {\AA} which is applicable to the field-use and also to the laboratory experiments. The Raman scattered radiation was observed in a direction perpendicular to the linearly polarized plane of the incident laser beam. The signal was processed by the pulse-gated photon counting method synchronized with the repetitive laser pulse, which is valuable for detecting extremely weak light signals. The accuracy of our measured cross sections is within 10\% and their values were found to agree well with the pre-laser result by Murphy et and the laser result by Fouche et for several gases. It is noteworthy that band has 15 times and band has 7.2 times larger cross section than that of , due possibly to resonance Raman effect at 3371 {\AA}
Specific and efficient targeting of cyanobacterial bicarbonate transporters to the inner envelope membrane of chloroplasts in Arabidopsis
No full textInstallation of cyanobacterial bicarbonate transporters to the inner envelope membrane (IEM) of chloroplasts in C3 plants has been thought to improve photosynthetic performance. However, the method to deliver cyanobacterial bicarbonate transporters to the chloroplast IEM remains to be established. In this study, we provide evidence that the cyanobacterial bicarbonate transporters, BicA and SbtA, can be specifically installed into the chloroplast IEM using the chloroplast IEM targeting signal in conjunction with the transit peptide. We fused the transit peptide and the mature portion of Cor413im1, whose targeting mechanism to the IEM has been characterized in detail, to either BicA or SbtA isolated from Synechocystis sp. PCC6803. Among the seven chimeric constructs tested, we confirmed that four chimeric bicarbonate transporters, designated as BicAI, BicAII, SbtAII, and SbtAIII, were expressed in Arabidopsis. Furthermore, these chimeric transporters were specifically targeted to the chloroplast IEM. They were also resistant to alkaline extraction but can be solubilized by Triton X-100, indicating that they are integral membrane proteins in the chloroplast IEM. One of the transporters, BicA, could reside in the chloroplast IEM even after removal of the IEM targeting signal. Taken together, our results indicate that the addition of IEM targeting signal, as well as the transit peptide, to bicarbonate transporters allows us to efficiently target nuclear-encoded chimeric bicarbonate transporters to the chloroplast IEM
Ethics for Humanity That May Not Perish
No full textThis work is an English translation of the book “Metsubousurukamosirenai Junrui no tameno Rinrigaku[Ethics for Humanity That May Perish: LongTermism, Transhumanism, and Space Exploration]” by author, Shin-ichiro Inaba, himself. The original Japanese version was written for introducing Longtermism, Existential Risk Theory and related topics to Japanese general readrers. Chapters One and Two trace the origins of longtermism as a theoretical framework and philosophy. Chapter 3 briefly summarizes the theoretical core of what longtermism is and introduces accelerationism and effective accelerationism as adjacent movements that also concern humanity in the super-future. Chapter 4 points out that animal ethics can become a stumbling block for longtermism—giving rise to a peculiar puzzle. Chapters Five and Six examine the difficult problems in intergenerational ethics raised by Parfit, keeping the context of longtermism in mind. Chapter Five focuses on the "repugnant conclusion," while Chapter Six centers on the "non-identity problem." Chapter 7 points out that the "Singleton", according to Bostrom, deemed essential for humanity to survive and develop long-term by overcoming "existential risks," could itself be a source of such risks. Chapter 8 introduces the "Fermi Paradox" – the puzzle of why, despite the vast number of celestial bodies in the universe, extraterrestrial intelligence (ETI) remains undiscovered – and demonstrates its deep structural and substantive connection to the theory of existential risks. Chapters 9 and 10 discuss the possibility and desirability of humanity's space exploration. In closing this book, we will briefly touch upon the "eschatological" aspects of these arguments

No full textReview Of Japanese Homes And Lifestyles: An Illustrated Journey Through History By K. Inaba And S. Nakayama, Translated By J. Bester
No full textInaba\u27s slight but costly volume, originally published in Japanese in 1983, is noteworthy for Nakayama\u27s illustrations. Modeled after David Macaulay\u27s series (Cathedral, Pyramid, City), they are exquisitely drawn albeit inevitably fanciful in certain details. But the text is academic and puerile; it reads like a middle school textbook. It assumes a rudimentary knowledge of Japanese history, not expected of the average reader of the translation, and yet, in discussing architecture, it is flatly descriptive with hardly any attempt at critical interpretation. The discussion is chronological but not historical; it lacks a large historical sense of connections and continuities. The author\u27s slant is folk architecture and the text thus slights the dwellings of the nobility and the ruling class--the shinden and the shoin--that have traditionally been overemphasized at the expense of farm houses and townhouses. The fruitful cross-fertilization of the urban and the rural, if that was the author\u27s interest, is not adequately articulated. No footnotes, no bibliography. Not for academic audiences
