Abstract: An information processing device includes one or more processors. The one or more processors are configured to optimize, for a specific elementary reaction in a reaction using a catalyst including a plurality of elementary reactions, an arrangement of a promoter element in the catalyst based on activation energy acquired using a trained model, and search for the promoter element based on the activation energy acquired using the trained model for each type of the promoter element.

Abstract: Provide is a metal-coated liquid-crystal polymer film that is suitable for microcircuit processing and capable of reducing the transmission loss of circuits. The metal-coated liquid-crystal polymer film comprising: a polymer film comprising a polymer film main body capable of forming an optically anisotropic melt phase; a first metal layer layered on at least one side of the polymer film main body; and a second metal layer layered on the first metal layer, wherein in an analysis of oxygen concentration in a thickness direction using XPS, the average oxygen concentration of the first metal layer is 2.5 atom % or less.

Abstract: The reduction of noise in the rotation of the tire and the improvement of resistance to hydroplaning are established and also the resistance to uneven wear is improved, in which four circumferential main grooves 2-5 are formed asymmetrically, and a sum of groove volume in a circumferential direction in lateral grooves formed in a shoulder land part row 7 as a portion of an axially inner side per unit width is made smaller than a sum of groove volume in the circumferential direction in lateral grooves 11 formed in a shoulder land part row 9 as a portion of an axially outer side and a land part row 6 in a central region is rendered into a rib, and slant grooves 13 extending at an average inclination angle of not less than 45° with respect to a widthwise direction of the tread are arranged in a second inner land part row 8 located at a side of an equatorial line adjacent to the shoulder land part row 7 at the axially inner side and these slant grooves 13 are opened to the circumferential main groove located adja

Abstract: This invention relates to a tire suitable in a passenger car, particularly a tire being high in the resistance to hydroplaning on a wet road surface and low in the tire noise and having an asymmetric tread pattern.
