Abstract: In order to address a conventional problem that there is no information processing apparatus for simulating processing in the brain, an information processing apparatus is configured such that one or more pieces of feature information are transferred between somas, each soma may fire using one or more pieces of accepted feature information, a firing pattern, which is a pattern of firing of one or more somas, is acquired, and output information corresponding to the firing pattern is acquired and output. Accordingly, it is possible to realize information processing for simulating processing in the brain. Also, it is possible to realize information processing for simulating processing in the brain, such as growth processing, apoptosis processing, and learning processing of elements such as somas.

Abstract: A base station, a mobile communication system and a handover control method are provided, which are capable of preventing a handover failure and a ping-pong handover phenomenon which are caused by an interference from a neighboring cell to a serving cell. When a received power difference (S2−S1) between a received power S2 from a neighboring second base station, which is fed back from a mobile station, and a received power S1 from first base station, becomes larger than a predetermined threshold value, the first base station to which the mobile station is connected requests the second base station to stop a transmission of a downlink signal including at least one of a data signal and a control signal. In response to the transmission-stop request, the second base station performs a determination of a radio resource in which the transmission of the downlink signal is to be stopped and a notification of the radio resource to the first base station, and stops a transmission of a downlink signal. The first base station allocates the radio resource notified from the second base station or a radio resource partially including the notified radio resource, as a radio resource used for the downlink signal to the mobile station.

Abstract: A communication system capable of realizing a three-dimensional network of the fifth generation mobile communication with low propagation delay in a radio communication is provided. The communication system comprises a radio relay station that relays a radio communication with the terminal apparatus. The radio relay station is provided in a floating object that is controlled so as to be located in a floating airspace with an altitude of 100 [km] or less by an autonomous control or an external control. When the floating object is located in the floating airspace, the radio relay station forms a three-dimensional cell in a predetermined cell-formation target airspace between the floating object and a ground level or a sea level.
