A field-effect transistor is created on a GaAs semi-insulating substrate (e.g. 100) using molecular beam epitaxy by fabricating a delta-doped monolayer with a silicon dopant between two undoped GaAs layers grown over the semi-insulating substrate. A plurality of delta-doped monolayers (e.g. 111, 112, 113, 114, 115) are grown over the surface of the upper undoped layer (e.g. 103) interleaved with l...

A backup method for a computer database system in which updates to the mirrored data of a remote database are delayed for a delay time greater than or equal to the communication delay between the local and remote databases and updates to a remote log for the database are executed after corresponding updates to a local log without such a delay. In this way a consistent copy of the database may be r...
