Oscar — 2022: Hamaguchi Ryūsuke
No full textThe article is devoted to the work of the famous Japanese film director Hamaguchi Ryūsuke — a representative of the new generation of Japanese cinematographers. He is the winner of many prestigious awards of the international film festivals in Locarno, Cannes, etc. His film Drive My Car received the prize of the American Film Academy, Oscar — 2022, as the best foreign film. The film is unusual and interesting in many of its features, which are described in detail in this paper. But, first of all, the author draws attention to the fact that the plot of this picture is based on the eponymous story by the popular Japanese novelist Murakami Haruki. At the same time, the director borrowed a lot from the play “Uncle Vanya”, written by Russian classic A. P. Chekhov, whose influence is quite evident in all the director’s recent works. Another key figure who determined the main vector of creativity of Hamaguchi is Andrei Tarkovsky. The Japanese director owes his acquaintance with Tarkovsky’s films to his teacher — a master of modern Japanese cinema Kurosawa Kiyoshi. Thus, the Russian theme is one of the most interesting aspects of his work. At the same time, the author seeks to analyze in details other literary and cinematic origins of Hamaguchi’s directorial career and comes to the conclusion that his work is a complex but harmonious synthesis of Western and Japanese culture with the latter’s pronounced national traditions
Triple point of Yukawa systems
No full textS. Hamaguchi, R. T. Farouki, and D. H. E. Dubin,Phys. Rev. E 56, 4671, 1997The molecular dynamics simulations of Yukawa (i.e., screened-Coulomb) systems that were applied to the regime of weak screening in an earlier study [S. Hamaguchi, R. T. Farouki, and D. H. E. Dubin, J. Chem. Phys. 105, 7641 (1996)] are extended to the strong screening regime. Transition temperatures at the fluid-solid phase boundary and the solid-solid phase boundary are obtained as functions of the screening parameter [Formula Presented] (i.e., the ratio of the Wigner-Seitz radius [Formula Presented] to the Debye length [Formula Presented]). The resulting phase diagram also covers the triple point—the intersection of the fluid-solid and solid-solid phase boundaries—at [Formula Presented] and [Formula Presented] where Γ is the ratio of the Coulomb potential energy to the kinetic energy per particle (i.e., [Formula Presented] where [Formula Presented] is the charge of each Yukawa particle and [Formula Presented] is the system temperature). Yukawa systems serve as models for plasmas and colloidal suspensions of charged particulates. © 1997 The American Physical Society

Such plasmas can serve as a powerful source of free radicals and/or chemically reactive species that arise from atoms and molecules of the ambient gas. Recently use of such plasmas for medical purposes has attracted much attention as they can be implemented in possible medical devices that can cause blood coagulation, heal wounds, facilitate angiogenesis, sterilize surgical devices as well as living tissues without harming healthy cells, and selectively inactivate cancer cells. Especially of interest among reactive species generated by atmospheric-pressure plasmas (APP) are reactive oxygen species (ROS) and reactive nitrogen species (RNS) that are generated in liquid phase. Since most living tissues and cells are immersed in liquids (such as blood or culture media), reactive species generated by APPs in the gas phase are transported to the liquid phase and possibly converted to different types of reactive species therein before causing some influence on the tissues or cells. In this study, the rate equations are solved to evaluate concentrations of various reactive species in pure water that are originated by plasma reactions in atmosphere and possible effects of such species (including ROS/RNS) on living tissues and cells are discussed
Japan and Economic Integration in East Asia: Post-disaster scenario
No full textAs regional integration proceeds in East Asia, intermediate goods production of advanced technology has been locked in Japan despite the dispersion forces of high factor costs. However, the disastrous earthquake in 2011 may have revealed supply chain disruption risk as another dispersion force. We analyze how these dispersion forces affect the specialization in intermediate goods production of Japan and discuss future competitive challenges for the Japanese economy under deindustrialization from the spatial economics viewpoint.
Dense Communication and R&D in Knowledge-based Industrial Clusters: Comparative Study of Small & Medium-sized Firms in Korea and China
No full textThis paper presents analyses of the effects of dense communication of industry-academia-government cooperation on enhancement and reduction of in-house R&D activities using survey data of the Seoul Digital Industrial Complex, Daedeok Valley, and Zhongguancun Science Park. Our results show that older firms, presumably with more-experienced personnel, take more advantage of R&D cooperation in large metropolitan areas, whereas in-house R&D of less-experienced younger firms is not influenced greatly by external knowledge. In a science park that is distant from the economic core region, we identified that encouragement by local organization toward R&D by less-experienced younger firms has considerable influence.R&D cooperation, industrial cluster, Seoul Digital Industrial Complex, Daedeok Valley, Zhongguancun Science Park

Phase diagram of Yukawa systems near the one‐component‐plasma limit revisited
No full textTransition inverse temperatures (or Γ values) at the fluid–solid phase boundary of Yukawa systems near the one‐component‐plasma (OCP) limit have been evaluated by molecular dynamics simulations. These values are systematically smaller than those obtained in an earlier study by Farouki and Hamaguchi [J. Chem. Phys. 101, 9885 (1994)]. The discrepancy is attributed to the fact that, in the earlier study, the harmonic entropy constants were approximated by that of the OCP, whereas the new results are based on more accurate harmonic entropy constants obtained from lattice‐dynamics calculations. The new molecular dynamics simulations also confirm that the bcc–fcc phase transition curve is in good agreement with that of the quasiharmonic theory in the regime κ≤1.4, where κ is the ratio of the Wigner–Seitz radius to the Debye length. Examples of Yukawa systems include dusty plasmas and colloidal suspensions. © 1996 American Institute of Physics.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/69874/2/JCPSA6-105-17-7641-1.pd
Analysis of a kinematic model for ion transport in rf plasma sheaths
No full textRida T. Farouki, Satoshi Hamaguchi, and Manoj Dalvie, Phys. Rev. A 45, 5913, 1992An idealized model for ion transport across an oscillating plasma sheath is analyzed to obtain insight into qualitative features of the ion energy distributions observed in low-pressure rf discharges. The sheath is characterized by a constant electric field over an extent that varies sinusoidally with time, and ions incident on it correspond to a monoenergetic flux independent of phase in the rf cycle. The dimensionless parameters =qVs/m2d2 and =v0/d (where d and Vs are the mean sheath thickness and potential drop, is the excitation frequency, and v0 and q/m are the incoming ion speed and charge-to-mass ratio) govern the ion trajectories, which are found to divide into groups, delimited by two critical values of , that undergo N and N+1 encounters with the field. The first critical phase depends only weakly on , whereas the second is sensitive to both and and cycles continuously as these parameters diminish. Correspondingly, within the transition regime where and are neither very small nor greater than (or comparable to) unity, the precise form of the incident-ion energy spectrum exhibits rapid variations, superposed on a systematic narrowing, as the frequency is increased. © 1992 The American Physical Society
Quantum cascade laser absorption spectroscopy with the amplitude-to-time conversion technique for atmospheric-pressure plasmas
No full textYumii, T., Kimura, N., and Hamaguchi, S., Journal of Applied Physics 113(21), 213101 (2013) http://doi.org/10.1063/1.4808261The NO2 concentration, i.e., density, in a small plasma of a nitrogen oxide (NOx) treatment reactor has been measured by highly sensitive laser absorption spectroscopy. The absorption spectroscopy uses a single path of a quantum cascade laser beam passing through a plasma whose dimension is about 1 cm. The high sensitivity of spectroscopy is achieved by the amplitude-to-time conversion technique. Although the plasma reactor is designed to convert NO in the input gas to NO2, it has been demonstrated by this highly sensitive absorption spectroscopy that NO2 in a simulated exhaust gas that enters the reactor is decomposed by the plasma first and then NO 2 is formed again, possibly more than it was decomposed, through a series of gas-phase reactions by the time the gas exits the reactor. The observation is consistent with that of an earlier study on NO decomposition by the same type of a plasma reactor [T. Yumii, J. Phys. D 46, 135202 (2013)], in which a high concentration of NO2 was observed at the exit of the reactor. © 2013 AIP Publishing LLC
Baking soda ingestion and the effects on endurance cycling
No full textHave you ever experienced a burning sensation in your muscles when you are exercising? This sensation, as well as muscle fatigue, comes from increased hydrogen ions (H+) in the muscle cell, which inhibits the rate of muscle contraction and decreases performance. Sodium bicarbonate (SB) acts as a natural buffering agent to reduce H+ which delays fatigue and improves aerobic performance. Purpose: Determine whether SB has a positive correlation on sustained aerobic performance.
Hypothesis: Ingesting sodium bicarbonate 1-hour prior to the FTP cycling test will decrease sustained power output and increase distance covered. Conclusion: There is no statistical significant difference between SB ingestion and sustained power output, however, recreational athletes looking to improve aerobic performance may utilize SB to improve power output and delay fatigue.Not peer reviewedStudent Research Day Poster (2019
