Abstract: A reference region determination device is for determining a reference region to be stored in a reference image buffer, and includes: a motion vector acquisition portion configured to acquire a motion vector for each one of already encoded blocks; a position change amount derivation portion configured to derive a position change amount for the reference region based on the acquired motion vectors; and a reference region determination portion configured to determine a position of the reference region to be used in encoding of a next block for encoding after the already encoded blocks based on the position change amount.

Abstract: Provided are group-III nitride nanoparticles that prevent the piezoelectric field caused by strains on the nanoparticles, achieving good luminous efficiency. The group-III nitride nanoparticle represented by AlxGayInzN (0?x, y, z?1) incorporating two crystal structures; a wurtzite structure and a zincblende structure, in a single particle. As another example, the group-III nitride nanoparticle has a core-shell structure with a core and a shell, in which the particle constituting the core contains two crystal structures; the wurtzite structure and the zincblende structure, in the particle. Nanoparticles containing the two crystal structures can be produced by using a phosphorus-containing solvent as a reaction solvent, and the mixture ratio of the two crystal structures, (wurtzite structure)/(zincblende structure), is 20/80 or higher.

Abstract: A server including a reception unit, a determination unit, a generation unit, and a transmission unit. The reception unit receives an acquisition request for a first page associated with a first channel that is one of a plurality of channels provided by a platform application from a terminal. The determination unit determines whether or not the acquisition request includes supplementary information indicating that a shortcut icon to the first page has been selected. The generation unit activates the platform application in a case where the acquisition request includes the supplementary information and generates a response to the acquisition request, the response including a command to perform screen transition to a second page associated with the first channel after the activation of the platform application.

Abstract: This invention provides a rust-proofed steel sheet for a fuel tank including an alloy layer containing at least one of Ni, Fe, Zn and Sn and deposited on the surface of a steel sheet to a thickness of 2 .mu.m per surface, and a Sn--Zn alloy plating layer consisting of 40 to 99 wt % of Sn and the balance of iron, containing not greater than 20 crystals/0.25 mm.sup.2 of zinc crystals having a major diameter of not greater than 250 .mu.m and deposited on the alloy layer to a thickness of 2 to 50 .mu.m per surface. The to-be-plated steel sheet to which the plating layer is applied has a composition consisting of C.ltoreq.0.1%, Si.ltoreq.0.1%, Mn: 0.05 to 1.2%, P.ltoreq.0.040%, Al<0.1% and if necessary, at least one of B, Ti, Nb and Cr, and the balance of Fe and unavoidable impurities. This invention provides also a production method of a rust-proofing steel sheet for a fuel tank comprising the steps of applying Ni--Fe type pre-plating to an annealed steel sheet in a quantity of 0.1 to 3.0 g/m.sup.
