Abstract: A player character's action is controlled based on a user's input. A first object associated with the player character is arranged at a position in a virtual space based on the user's input with reference to a position of the player character. In the virtual space, a region having an extent in a horizontal direction set based on a height in the virtual space at which the first object is arranged, the region including a position related to the horizontal direction of the first object, is set as a first region related to the user. The player character's action is controlled such that a predetermined action has a form varying depending on whether or not the player character is located in the first region.

Abstract: In a virtual space, a state of at least one of a first object and a second object that is associated with a first user is changed based on a first user's input. A first region related to the first user is set based on a position of the second object arranged with reference to a position of a first player character. A state of at least one of the first object and a second object that is associated with a second user is changed based on the second user's input. Changing of states of the first and second objects in the first region based on the second user's input is limited.

The exemplary information processing system updates a second parameter, based on the number of the unit areas having been changed from the first state to the second state according to either the predetermined action performed by the player character, or the predetermined action performed by another player character corresponding to another player different from the player.

Abstract: An objective of the present invention is to provide an amplification fiber having a cladding excitation configuration that improves amplification efficiency and an optical amplifier. An amplification fiber (10) according to the present invention is a multi-core amplification fiber having, from one end (E1) to the other end (EE), a plurality of cores (11b) in a cladding (11a), and a total distance from the one end (E1) to the other end (EE) in which rare earth ions are doped differs depending on the types of cores (11b). The cores (11b) are preferably disposed such that the cores of the same type are not adjacent to each other. By arranging the types of the cores in this manner, requirements for inter-core crosstalk can be mitigated since the bands of signal light in the adjacent cores are different. As a result, a density of cladding excitation light can be increased by shortening the inter-core distance, and thus the amplification efficiency can be improved.
