An Analysis of the ICNND: The Japan-Australia Collaboration for Nuclear Abolition
Akimoto, Daisuke 서울대학교 통일평화연구원 2014 Asian Journal of Peacebuilding Vol.2 No.1
The Japanese and Australian governments supported the establishment of the International Commission on Nuclear Non-proliferation and Disarmament (ICNND) in 2008. During its two-year mandate, the ICNND organized international conferences in Sydney, Washington, Moscow, and Hiroshima. The commission made specific proposals in a final report entitled Eliminating Nuclear Threats: A Practical Agenda for Global Policy Makers. This research note examines the significance of the report, while paying special attention to its limitations. In particular, this study criticizes the nuclear policies of Japan and Australia that have depended upon U.S. extended nuclear deterrence and peaceful use of atomic energy. Finally, it suggests five alternatives for Japan and Australia so that both countries can resume further endeavors towards a world free of nuclear threats.

Fluorescence rise and decay curves of carotenoids were measured in solutions and in pigment protein complexes with a femtosecond time-resolved fluorescence spectroscopy. For linear carotenoids, the S$_2$ lifetimes showed the maximum value around n = 9-10. The conjugation of a keto-carbonyl group shortened the S$_2$lifetime and prolonged the S$_1$lifetime. The excitation relaxation dynamics within carotenoids and the excitation energy transfer kinetics from carotenoids to chlorophylls are discussed as a function of molecular structure of carotenoids.

A unsteady RaNS code is applied to simulate MOERI container ship model, KCS, in regular head sea conditions. Various combinations of Froude's number, wave length and wave height are simulated. With respect to the integral quantities, a comparison between simulation and experimental results shows that the computed amplitude of heave and pitch motions are in well agreement each other. However, the first-order harmonic amplitudes of heave are significantly under predicted by the present simulations.
Benjamin Strong and International Financial Cooperation during the 1920s
Eiichi Akimoto 서울대학교 미국학연구소 2010 미국학 Vol.33 No.1
Benjamin Strong (1872-1928) was an “elite” banker, who first engaged in founding of the Federal Reserve System in 1913. Later he served as governor of the Federal Reserve Bank of New York (1914-1928). Already in 1916 Strong found that he had tuberculosis. After struggling for years, the disease would finally take his life. In their A Monetary History of the United States, Friedman and Schwartz wrote: If Strong had still alive and head of the New York Bank in the fall of 1930, he would very likely have recognized the oncoming liquidity crisis for what it was, would have been prepared by experience and conviction to take strenuous and appropriate measures to head it off, and would have had the standing to carry the System with him. When Strong was governor of the FRB of New York, the system itself was in its infancy, and the New York bank was more powerful than the Federal Reserve Board itself. Strong played a similar role of Ben Bernanke, the current Chairman of the Board of Governors of the United States Federal Reserve, although organizationally the New York Bank was just only one of twelve regional banks under the FRB. Strong’s most important task was to recover and stabilize world economy through the restoration of world gold standard and he needed cooperation of Montague Norman of the Bank of England among others, and also of Emile Moreau of the Bank of France, and Hjalmar Schacht of the Reichsbank of Germany in these efforts. He succeeded in rebuilding the gold standard beginning with Britain. The reconstructed monetary system was different from the prewar system governed by Britain, mainly because of the heavy concentration of gold to the U.S. and France. Strong took great pains to control the rates of interest to avoid deflation on the one hand, and to “sterilize” gold coming into the U.S. to keep off inflation on the other. The international financial cooperation led by Strong had been disintegrating towards the end of 1920s, because the alienation of economic interests between the U.S. and European countries inevitably widened during this period.
New Aspects of the Correlation Functions in Non-Hyperbolic Chaotic Systems
Takuma Akimoto,Yoji Aizawa 한국물리학회 2007 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.50 No.1I
The initial ensemble dependence of statistical laws in non-hyperbolic dynamical systems with in.nite ergodicity are studied by use of the modi.ed Bernoulli maps. We show that statistical laws crucially depend on the initial ensemble and that the time average for the Lyapunov exponent converges in distribution for the non-stationary regime. This is completely consistent with the Darling-Kac-Aaronson (DKA) limit theorem from the fact that the Lyapunov exponent is an L1 ¹- class function. Next, we study the correlation function, which is not an L1 ¹-class function. The most remarkable result is that the transformed correlation function also reveals uniform convergence in distribution in the same sense of the DKA limit theorem.
