Abstract: An object is to provide a technique of suppressing increase in a calculation load by an elaborate vehicle model. A control calculation apparatus includes: a first trajectory generation unit generating a first trajectory of a vehicle in a first prediction period based on a first vehicle model and a first place; a second trajectory generation unit generating a second trajectory of the vehicle in a second prediction period based on a second vehicle model having a degree larger than a degree of the first vehicle model, a second place different from the first place, and the first trajectory; and a target value calculation unit calculating and outputting a target value based on the second trajectory.

Abstract: Provided is an improved estimation and identification device that estimates the position of a plurality of identification targets and identifies the plurality of identification targets.

Abstract: This embolic material is produced by a production method including a step for dispersing a mixture that contains a biodegradable polymer, an oil-based contrast agent, and a solvent in a hydrophilic liquid. The biodegradable polymer has a hydrophobic biodegradable polymer.

Abstract: A stopper portion includes a first protruding portion protruding from the end face of the first attachment portion closer to the outside in the main load input direction toward the outside in the main load input direction; and a second protruding portion protruding from the end face of the first attachment portion closer to the outside in the main load input direction toward the outside in the main load input direction, being spaced apart from the first protruding portion so as to be in a non-contact state with the first protruding portion, being thinner than the first protruding portion in the main load input direction, and having a protruding end in which a distance between the protruding end and the contact surface is longer in the main load input direction than a distance between a protruding end of the first protruding portion and the contact surface.
