Abstract: A ceramic sintered body according to an aspect of the present disclosure has a composition represented by R3Ga5O12 or R3Al5O12 (R represents at least two rare earth elements), and has an overall porosity of 10% or more and 30% or less.

Abstract: A data generation system includes a division unit, an extraction unit, an output unit, an input unit, and a generation unit. The division unit divides each of the plurality of sentences into tokens. The extraction unit extracts a sentence including candidates for a token to be combined as a word from a plurality of sentences based on characteristics of tokens included in the plurality of sentences. The output unit outputs a sentence including the candidates for the token to be combined. The input unit receives, as an input, an instruction to combine the candidates for the token to be combined included in the sentence output by the output unit. The generation unit generates a language resource including a word obtained by combining the candidates for the token to be combined based on the input.

Abstract: Disclosed is a sintered body comprising (a) a matrix material comprising at least one selected from ZnS and ZnSe, (b) an oxide that is present in a form of islands in the matrix material, comprising at least one metal selected from the group consisting of Ca, Sr and Ba, and (c) pores that are present in a form of islands in the matrix material. The sintered body has sufficient strength and an infrared stealth effect in an infrared region such as a MWIR and LWIR region.

Abstract: An analysis system is configured to include an extraction unit, an output unit, an acquisition unit, and a dictionary generation unit. The extraction unit extracts, as a token pair, two tokens that consecutively occur in a sentence separated using the basic dictionary. Regarding a token in which two tokens included in a token pair are connected, the output unit displays a selection screen for selecting any of registering with a dictionary, registering with an on-hold list for holding registration with the dictionary, and not registering with the dictionary. The acquisition unit acquires a selection result for the selection screen. The dictionary generation unit generates an on-hold list with which the token pair whose selection result indicates on-hold is registered as a token, and a dictionary with which the token pair whose selection result indicates registering is registered as a connected token.

Abstract: A radiation suppression film includes a porous body containing a material transparent to a long wavelength infrared ray as a base material.
