Abstract: One aspect of the application can provide a system and method for replacing a failing node with a spare node in a non-uniform memory access (NUMA) system. During operation, in response to determining that a node-migration condition is met, the system can initialize a node controller of the spare node such that accesses to a memory local to the spare node are to be processed by the node controller, quiesce the failing node and the spare node to allow state information of processors on the failing node to be migrated to processors on the spare node, and subsequent to unquiescing the failing node and the spare node, migrate data from the failing node to the spare node while maintaining cache coherence in the NUMA system and while the NUMA system remains in operation, thereby facilitating continuous execution of processes previously executed on the failing node.

Abstract: A charged particle beam detection system that includes a Faraday cup detector array (FCDA) for position-sensitive charged particle beam detection is described. The FCDA is combined with an electronic multiplexing unit (MUX) that allows collecting and integrating the charge deposited in the array, and simultaneously reading out the same. The duty cycle for collecting the ions is greater than 98%. This multiplexing is achieved by collecting the charge with a large number of small and electronically decoupled Faraday cups. Because Faraday cups collect the charge independent of their charge state, each cup is both a collector and an integrator. The ability of the Faraday cup to integrate the charge, in combination with the electronic multiplexing unit, which reads out and empties the cups quickly compared to the charge integration time, provides the almost perfect duty cycle for this position-sensitive charged particle detector. The device measures further absolute ion currents, has a wide dynamic range from 1.

Abstract: A charged particle beam detection system (10) that includes a Faraday cup detector array (FCDA) for position-sensitive charged particle beam detection is described. The FCDA is combined with an electronic multiplexing unit (MUX) (2) that allows collecting and intgrating the charge deposited in the array, and simultaneously reading out the same. The duty cycle for collecting the ions is greater than 98%. This multiplexing (2) is achieved by collecting the charge with a large number of small and electronically decoupled Faraday cups. Because Faraday cups collect the charge independent of their charge state, each cup is both a collector and an integrator. The ability of the Faraday cup to integrate the charge, in combination with the electronic multiplexing unit (2), which reads out and empties the cups quickly compared to the charge integration time, provides the almost perfect duty cycle for this position-sensitive charged particle detector (10).

Abstract: The present invention provides an instrument and methods for the preparative separation of components of mixtures using mass spectrometric methods. Nondestructive ionization methods are employed to generate ionized components of a mixture, the ionized components are spatially separated by mass and the mass-separated ion components are trapped. The ion source and mass spectrometric techniques employed allow the generation of large ion currents of ion components, on the order of nanoamps, which facilitate rapid accumulation of nanomole quantities of mass-separated components in relatively short times (minutes to hours).

Abstract: A support including a plurality of spaced plates coextensive and parallel to one another in a fixed relationship, including a slider plate mounted therebetween, wherein the slider plate is extensible relative to the top and bottom plates that are secured together for positioning upon an individual's shoulder. The slider plate includes a slot with an abutment member cooperative with a set screw to prevent removal of the slider plate relative to the top and bottom plates. Spring detent means are provided to maintain the slider plate between the top and bottom plates in a stored configuration.
