Abstract: An object is to provide a user with motivation to enjoy waking up in the morning and guide the user to sufficient awakening by generating a breeding event in a breeding game of a virtual life form when the user wakes up in the morning. A game server that manages progress of a breeding game of a virtual life form can provide a user with motivation to enjoy waking up in the morning and guide the user to sufficient awakening by generating a breeding event in a breeding game of a virtual life form when the user wakes up in the morning. The game server includes circuitry configured to acquire a wake-up time of a user; and a update the breeding game in accordance with the acquired wake-up time.

Abstract: Provided is a material that, when compared with SAPd, exhibits the similar activity in cross-coupling (CC) reactions, can decrease the amount of catalytic metal that is mixed into the reaction product, and increases the number of times use can be repeated. Provided are a catalyst and a catalyst precursor that use a catalytic metal other than Pd and that exhibit the CC reaction activity similar to when Pd is used. Provided are a catalyst and a catalyst precursor that exhibit the similar CC reaction activity when using Pd or a catalytic metal other than Pd, without using a carrier such as metal and without using piranha solution. A composite wherein catalytic metal nanoparticles are dispersed in a continuous phase comprising a polymer having C2-6 alkylene group units and phenylene group units (an alkylene group unit being bonded to at least the first and fourth position of the phenylene group unit). The particle diameter of the catalytic metal nanoparticles is at most 20 nm.
