Itō, Michio (1893–1961)

Michio Itō was a modern dancer and choreographer who worked in Europe, the United States, and Japan. After training at the Dalcroze Institute in Hellerau, Itō collaborated with Ezra Pound and W.B. Yeats on the 1916 dance drama, At the Hawk’s Well. In New York City, Itō performed at the Neighborhood Playhouse and the Greenwich Village Theatre, and taught and worked with U.S. modern dancers, including Martha Graham, Charles Weidman, Pauline Koner, Ruth St. Denis, and Lester Horton. Itō moved to Los Angeles in 1929, where he worked in film and choreographed dance symphonies for the Hollywood and Pasadena Rose Bowls. Following the events at Pearl Harbor Itō was interned, and repatriated to Tokyo in 1943. When the war ended he became head choreographer of the Ernie Pyle Theatre in Tokyo, creating productions for the occupying troops. Itō developed his own modern dance technique, the Itō Method, which adapted Dalcroze movement exercises into a style that he described as a fusion of ‘‘East’’ and ‘‘West.’’ Itō’s intercultural approach and ability to move between elite and commercial projects allowed him to cross different streams of modernism—German eurhythmics, British poetic drama, U.S. modern dance, and the Americanization of postwar culture in Japan.

3-Axis NC Rough Tool-Path Generation from Discrete Data Points of Reliefs

This paper presents an algorithm through which 3-axis NC rough tool-paths can be directly generated from discrete data points. Based on Inverse Tool Offset (ITO) method, the algorithm generates direction-parallel (DP) tool paths for relief point clouds. The algorithm includes four steps: dividing data points into 3D cell grids; constructing inverse tool model and calculating the grids intersecting the surface of inverse tool; obtaining the grids containing cutter location points; calculating tool paths. The experiment results indicate that the algorithm of the rough tool paths is efficient.

The backward Îto method for the Lagrangian simulation of transport processes with large space variations of the diffusivity

Random walk models are a powerful tool for the investigation of transport processes in turbulent flows. However, standard random walk methods are applicable only when the flow velocities and diffusivity are sufficiently smooth functions. In practice there are some regions where the rapid but continuous change in diffusivity may be represented by a discontinuity. The random walk model based on backward Îto calculus can be used for these problems. This model was proposed by LaBolle et al. (2000). The latter is best suited to the problems under consideration. It is then applied to two test cases with discontinuous diffusivity, highlighting the advantages of this method.

Luddenite, a new copper-lead silicate from Arizona

Found at a small prospect in the Artillery Peaks area, Arizona. Luddcnite occurs in oxidized Cu-Zn ores with fluorite, alamosite, and cerussite. Colour nickel green, H = 4, G meas. 4.45.Strongest X-ray lines are 7.361(10), 3.173(10), 2.918(8), 5.218(7), 4.226(5), 3.411(5), 2.888(5), 3.650(4). A possible cell found by Ito method is a = 7.85, b = 20.06, c = 14.72 Å, β = 90.78° (monoclinic). Optically (+), α = 1.852, γ = 1.867.Chemical analysis by wet methods gave CuO 13.2%, PbO 35.1, SiO2 25.7, H2O 20.5, TiO2 (leucoxene impurity) 4.7. Not all water need be essential, hence Cu2Pb2Si5 O14·nH2O. The new mineral and name have been approved in advance of publication by the Commission on New Minerals and New Mineral Names, IMA.

Cuzticite and eztlite, two new tellurium minerals from Moctezuma, Mexico

The new minerals were found together in oxidized ores at the Bambolla mine, Moctezuma, Sonora. Both occur with various iron oxides, emmonsite, schmitterite, and kuranakhite. Cuzticite, Fe2TeO6 · 3H2O, is yellowish, H = 3, G = 3.9, occurring as crusts with a scaly structure. No single crystals were found, but X-ray powder data indicate a hexagonal cell a = 5.045, c = 14.63 Å. Strongest lines are 3.256 (10), 2.518 (7), 4.871 (4), 2.239 (3), and 1.564 (3).Eztlite, Fe6Pb2(TeO3)3TeO6(OH)10 · nH2O, is blood red, as paper-thin sparkling crusts, H = 3, G = 4.5. A possible cell found by the Ito method is monoclinic a = 6.58, b = 9.68, c = 20.52Å, β = 90° 15′; strongest lines are 3.426 (10), 3.289 (10), 4.037 (9), 3.239 (9), and 2.445 (7B).Both minerals and their names have been approved by the Commission on New Minerals and Mineral Names, IMA.
