Abstract: A processing system detects excessive requests sent on behalf of a virtual machine executing at the processing system within a predetermined period of time and denies subsequent requests sent on behalf of that virtual machine until after the predetermined period of time has elapsed in order to grant access to resources of the processing system for servicing requests from other virtual machines and to prevent a virtual machine that has been compromised by an attack from overwhelming the processing system with malicious requests. The processing system sets a threshold number of event requests for each type of event request that can occur within a predetermined period of time. If the number of event requests of a certain type exceeds the threshold for that event type, the processing system ignores subsequent event requests of that type until the predetermined period of time has expired.

The surface (111) of the strontium titanate substrate is cleaned by heat-treating the strontium titanate substrate in the molecular beam epitaxy chamber.

The magnetically doped topological insulator quantum well film is formed on the surface (111) of the strontium titanate substrate. The amount of the hole type charge carriers introduced by the doping with Cr is substantially equal to the amount of the electron type charge carriers introduced by the doping with Bi.
