Abstract: Disclosed is an apparatus configured to support growth of a 3D, hollow organoid. The apparatus contains a support structure and an enclosure, wherein a number of cells positioned between the support structure and the enclosure can grow on/around the support structure to form the organoid. The support structure additionally contains openings such that a fluid within the structure can flow into the organoid. The support structure may also extend between two fluid reservoirs configured to supply a fluid to the structure and organoid. The entire apparatus may be formed from an additive manufacturing process.

Abstract: A pluggable apparatus of a circuit board is provided, which solves the problem that hot plugging of a Peripheral Component Interconnect Express (PCI-E) card is difficult to implement. The pluggable apparatus of the circuit board includes a base plate, a pulling strip, a rotating member, and a carrier plate, where the pulling strip is movably connected to the base plate by using a transverse guide mechanism, sawteeth are formed on a body of the pulling strip, the pulling strip further includes a handle that extends out of the base plate; the rotating member is in a bending line shape; the carrier plate is movably connected to the base plate by using a longitudinal guide mechanism; and a clamping trough is disposed on the carrier plate and is configured to fasten the circuit board.

Abstract: A container data center includes one container body and at least one cabinet set that is arranged in the container body in one direction. Each cabinet set includes at least one cabinet, and a direction in which the at least one cabinet is arranged is perpendicular to the direction in which the cabinet set is arranged. Bottoms of all cabinets in each cabinet set are fastened on one shock absorbing platform, and a bottom of the shock absorbing platform is fastened to a bottom of the container body by using multiple shock absorbers. The container data center can reduce an impact of vibration and a shock on a data center pipe in a transportation process.
