The hardware processor is configured to implement a first hypervisor and a second hypervisor. The first hypervisor controls execution of a first virtual machine. The second hypervisor performs communication with the first hypervisor via a gateway and controls execution of a second virtual machine. The hardware processor is configured to dynamically limit at least one of a communication traffic of application communication or a communication traffic of evaluation and verification communication, based on the application communication executed between the first hypervisor and the second hypervisor, and the evaluation and verification communication executed between the first hypervisor and the second hypervisor during activation of the first virtual machine and the second virtual machine, and based on a communication capacity of the gateway.

Abstract: A method of screening for a substance that acts on a cell mass includes producing a cell mass by three-dimensional culture of primary cancer cells using a tumor tissue, adding a test substance to the cell mass, and evaluating an action of the test substance on the cell mass. The cell mass is produced by culturing cells obtained from the tumor tissue in a medium containing a 5% v/v or less extracellular matrix on a substantially low-adhesive cell culture substrate and producing the cell mass of the primary cancer cells.

Abstract: A sliding member includes a base material and an alloy layer that includes Cu as a main component and Bi and having a sliding surface formed on a side opposite to the base material. The alloy layer has a first region and a second region. The first region is set to a region taking up 30% of the thickness of the alloy layer which is from an interface in contact with the base material toward the sliding surface. The second region is set to a region taking up 10% of the thickness of the alloy layer which is from the sliding surface toward the base material. A larger number of Bi phases having larger cross-sectional areas are distributed in an arbitrary observation cross section as Bi phases included in the second region compared to Bi phases included in the first region.
