Abstract: In some examples, a load on a first node of a plurality of nodes, over a period of time, may be determined based at least in part on comparing a load parameter with a load threshold. When the load parameter exceeds the load threshold, one or more nodes may be randomly selected from the plurality of nodes. Furthermore, an access load to move from the first node may be determined. The access load may correspond at least partially to data access requests received from user computing devices over the period of time. In addition, at least one node from the randomly selected one or more nodes may be determined that is able to receive the access load. A portion of data may be transferred from the first node to the at least one node. For instance, the portion of data transferred may be based on the access load.

Abstract: Provided are a treatment method, a separation method, and a filter assembly capable of preventing so-called “Blue Toe syndrome” which is so-called cholesterol crystal embolism of which a fat-soluble compound such as cholesterol crystals generated during dilation of a stenosed site causes clogging in glomeruli of peripheral capillaries or kidney, acute renal failure, and the like. Cholesterol crystals generated from plaque during use of a balloon catheter are taken out of the body and removed using a centrifugal separation device or a filter, and usable living cells are returned to the body to reduce blood transfusion and reduce cholesterol crystal embolism.
