Abstract: The objective is to provide an emotion determination system and the like for determining the emotion of an animal by a simple method. The emotion determination system comprises: an acquisition unit for acquiring an image of an animal; a behavior information generation unit for generating behavior information relating to a behavior of the animal from the image of the animal acquired by the acquisition unit; and an emotion determination unit for determining the emotion of the animal based on the behavior information generated by the behavior information generation unit.

Abstract: With respect to a reflective mask blank for a reflective mask used in EUV lithography using EUV light, the reflective mask blank including a substrate, a multilayer reflection film having a periodically laminated structure in which low-refractive index layers composed of a material containing molybdenum and high-refractive index layers are alternately laminated, a protection film, and an absorber film is provided. The low-refractive index layer consists of one or more of first low-refractive index sublayers, and one or more of second low-refractive index sublayers that have a different composition from a composition of the first low-refractive index sublayer.

Abstract: A fine and preferable pattern of an absorption film can be formed from the absorption film that can be patterned by dry etching using a gas containing oxygen (O) by a reflective mask blank including a substrate, a multilayer reflection film that is formed on one main surface of the substrate, and reflects exposure light, an absorption film that is formed on the multilayer reflection film, and absorbs the exposure light, and an etching mask film containing niobium (Nb) on the absorption film.

Abstract: As a reflective mask blank that includes a protection film containing ruthenium (Ru), a reflective mask blank in which the protection film is hard to be damaged and can be suppressed decrease of the thickness is provided by a reflective mask blank including a substrate, a multilayer reflection film, a protection film, an absorption film, and an etching prevention film that contains niobium (Nb) and is free of ruthenium (Ru) between the protection film and the absorption film.

Abstract: Disclosed is a communication technology in which the effect of packet loss can be easily reduced to the extent that it can be ignored, even on networks where packet loss can easily occur. Specifically, a communication device is disclosed that includes a packet loss determination unit that determines whether a packet that transmits image information has been lost, and an interpolated packet transmission unit that transmits an interpolated packet when a packet that transmits image information has been lost.

Abstract: Task: To provide communication technology in which clock synchronization accuracy can be easily maintained, even on networks where packets can be easily lost. Resolution Means: A communication device, comprising: a transmission unit that includes a flag processing unit that, upon receipt of one or a plurality of MPEG-2 TS packets, applies flag information to the packets at a predetermined interval in the forward reproduction direction of the packets, and a time stamp application unit that generates MPEG-2 TTS packets by applying a time stamp value calculated using a GPS clock to each of the one or a plurality of MPEG-2 TS packets, including the MPEG-2 TS packets having the flag information applied by the flag processing unit, and transmits the MPEG-2 TTS packets to a transmission path.
