    This English version of 吾輩は猫である (Wagahai-wa neko de aru: I Am a Cat), Chapters I and II, written by Natsume Sōseki, pseudonym of Natsume Kinnosuke (1867–1916), and translated by Kan-ichi Ando (1878-1924), was published by Hattori Shoten, Tokyo, in 1906. It begins: I am a cat; but as yet I have no name. Its sardonic feline narrator describes his origins, his settlement in the household of a Meiji teacher-intellectual, and the goings-on and conversations among the cats and humans about the neighborhood. Of the men he concludes: They are miserable creatures in the eyes of a cat. Japanese novelist Natsume Sōseki studied literature in England and became professor at Tokyo Imperial University. The success of his stories, beginning with I Am a Cat, launched a successful career that produced 22 novels, including Botchan, Kokoro, and Light and Darkness.

    Ten Nights\u27 Dreams and Our Cat\u27s Grave

    Ten Nights’ Dreams (夢十夜, Yume Jūya) is a classic written work from the Japanese master Natsume Soseki. Originally published in 1908, it announced the emergence in Japanese literature of a modernist and impressionistic mode. Short ­vignettes with fantastic, tragic, or magical events convey an exquisite sensibility compounded with stark realism. Love, honor, duty, artistry, desire, despair, and regret all shape events in the dream-world. The stories themselves suggest echoes of meanings beyond the failures of rational sense-making. Ten dreams—each unique and arresting—form a panorama of life and feeling, at once universal and intensely present. “Our Cat’s Grave” is a brief but heartfelt monody for a feline companion. Encompassing both the affection and the neglect, it becomes a meditation on empathy and helplessness, and on the transience of life and the persistence of memory. Translated By Sankichi Hata and Dofu Shirai. Frontispiece by Shigejiro Sano. Cover illustration by Takehisa Yumeji.https://digitalcommons.unl.edu/zeabook/1119/thumbnail.jp

    A Method of Treating Two-Dimensional Elasticity by Means of Integral Equation

    Get PDF
    This paper will give one method for attacking Airy's stressfunction in two-dimensional problems of elasticity by means of integral equation, when any distribution of external forces are given on a specified bounding curve. The example here given is very simple, but the method will suggest how to find the proper form of stress-function for more complicated boundary-value problems.Article信州大学工学部紀要 5: 1-8 (1955)departmental bulletin pape

    On the Elastic Waves with the Discrepancy between Tangential Displacements at the Junction of Two-Dimensional Layered Media

    Get PDF
    In this article, we propose the existence of some dispersive Rayleigh-waves propagated within the superficial layer of two-dimensional layered media. They are not only M-waves and M舀 -waves taken as the unique solutions whenever some physical constants are given, but also the other elastic waves propagated with some slide at the junction. If we regard M-waves and M舀 -waves with no slide whatever at the junction as the upper limit, we may regard some elastic waves with such slide that makes the strainenergy of the whole elastic system minimum as the lower limit. In this article, we shall find the lower limit and illustrate the solutions of such elastic waves are not unique but exist in certain ranges.Article信州大学工学部紀要 12: 1-34 (1961)departmental bulletin pape

    A New Approach to Stochastic State selections in Quantum Spin Systems

    Full text link
    We propose a new type of Monte Carlo approach in numerical studies of quantum systems. Introducing a probability function which determines whether a state in the vector space survives or not, we can evaluate expectation values of powers of the Hamiltonian from a small portion of the full vector space. This method is free from the negative sign problem because it is not based on importance sampling techniques. In this paper we describe our method and, in order to examine how effective it is, present numerical results on the 4x4, 6x6 and 8x8 Heisenberg spin one-half model. The results indicate that we can perform useful evaluations with limited computer resources. An attempt to estimate the lowest energy eigenvalue is also stated.Comment: 10 pages, 2 figures, 8 table

    A Note on the Stress Distribution in a Plate Flanged with a Circular Plug

    Get PDF
    This article gives a note on the old problem that a large plate flanged with a circular plug is subjected to a pair of edge forces. It is based on the principle of the minimum strain-energy of the whole system, by allowing the discrepancy between tangential displacements at the junction of the plate and the plug. Numerical calculation reveals a considerable increase in the maximum circumferential tensile stress.Article信州大学工学部紀要 6: 135-150 (1956)departmental bulletin pape
