Matsumoto metrics of reversible curvature
No full textIn this paper, we study the reversibility of Riemann curvature and Ricci curvature for the Matsumoto metric and prove three global results. First, we prove that a Matsumoto metric is R-reversible if and only if it is R-quadratic. Then we show that a Matsumoto metric is Ricci-reversible if and only if it is Ricci-quadratic. Finally, we prove that every weakly Einstein Matsumoto metric is Ricci-reversible

... : Variations around two schemes of T. Matsumoto and H. Imai
No full textIn [4], H. Imai and T. Matsumoto presented some new candidate trapdoor one-way permutations with a public key given as multivariate polynomials over a finite field. One of these schemes was later presented in [7] under the name C , and was based on the idea of hiding a monomial field equation. This scheme was broken in [8] by Jacques Patarin, due to unexpected algebraic properties. J. Patarin and L. Goubin then suggested ([9], [10], [11], [12]) some schemes to repair C , but this was done at the cost of slightly more complex public key or secret key computations. In part I of this paper, we will study some very simple variations of the C scheme, where the attack of [8] is avoided, and where the very simple secret key computations are kept. The C \Gamma+ scheme will be one of these variations. We will design some new cryptanalysis that are efficient against some of -- but not all -- these variations. Another scheme of [4], very different from C (despite the name), was call..

First description of the Minnesota Earth System Model for Ocean biogeochemistry (MESMO 1.0)
No full textHere we describe the first version of the Minnesota Earth System Model for Ocean biogeochemistry (MESMO 1.0), an intermediate complexity model based on the Grid ENabled Integrated Earth system model (GENIE-1). As with GENIE-1, MESMO has a 3D dynamical ocean, energy-moisture balance atmosphere, dynamic and thermodynamic sea ice, and marine biogeochemistry. Main development goals of MESMO were to: (1) bring oceanic uptake of anthropogenic transient tracers within data constraints; (2) increase vertical resolution in the upper ocean to better represent near-surface biogeochemical processes; (3) calibrate the deep ocean ventilation with observed abundance of radiocarbon. We achieved all these goals through a combination of objective model optimization and subjective targeted tuning. An important new feature in MESMO that dramatically improved the uptake of CFC-11 and anthropogenic carbon is the depth dependent vertical diffusivity in the ocean, which is spatially uniform in GENIE-1. In MESMO, biological production occurs in the top two layers above the compensation depth of 100 m and is modified by additional parameters, for example, diagnosed mixed layer depth. In contrast, production in GENIE-1 occurs in a single layer with thickness of 175 m. These improvements make MESMO a well-calibrated model of intermediate complexity suitable for investigations of the global marine carbon cycle requiring long integration time

Rozarium Shinjuku, przechadzka. Quasi-dokumentalny portret japońskiej społeczności queer w "Żałobnej paradzie róż" ("Bara no Sōretsu", reż. T. Matsumoto, 1969)
No full textThis essay explores the intricate interplay between documentary and narrative elements in the film Funeral Parade of Roses (Bara no Sōretsu, dir. T. Matsumoto, 1969). The film centers on the character of Eddie, a queer individual working as a hostess in a gay bar in Tokyo’s Shinjuku district. The narrative intertwines Eddie’s romantic relationship with the bar owner Gonda and his conflict with the establishment’s manager Leda. Flashbacks to Eddie’s childhood and the revelation that Gonda is his long-lost father have led many Western scholars to interpret the film as a loose adaptation of Oedipus Rex. However, this essay challenges such readings, proposing an analysis of the film through the lens of gender and sexual identity in 1960s Japan. The study integrates elements of Western theory (Ch. Baudelaire, W. Benjamin, G. Deleuze, F. Guattari, S. Sontag) with research on the specificity of Japanese culture (D. Desser, A. Jacoby, M.J. McLelland, A.M. Nornes, D. Richie, T. Satō, T. Schmidt, I. Standish), as well as insights from the director (T. Matsumoto) and his interpreters (M. Ko, M. Raine). The chosen methodology facilitates an exploration of the relationship between the individual and reality as depicted in documentary form. By employing the concept of the flâneur to capture the essence of Shinjuku, the author emphasizes the film’s eclecticism, which, through diverse conventions and cultural influences, creates a nuanced portrayal of Japan’s sexual minorities and offers a commentary on the impact of foreign influences on Japanese collective society
