Abstract: A set of 2D reconstructed images is generated from a pretreatment 3D scan showing an initial position of a target, wherein the set of 2D reconstructed images corresponds to perturbations from said initial position along fewer than six degrees of freedom. Said set of 2D reconstructed images are registered with one or more 2D x-ray images of said target showing a current position of the target, wherein the registering includes computing a set of 3D transformation parameters that represent a change in position of said target between said initial position of said pretreatment 3D scan and said current position of said 2D x-ray images along six degrees of freedom. A positioning system is instructed to adjust a relative position of a radiosurgical beam generator to said target by an amount prescribed by said 3D transformation parameters, wherein said target is allowed six degrees of freedom of position.

Abstract: A method for the separation of particles of different densities using a step-wise gradient density extraction method as described herein where a sample is suspended in a liquid volume of an extracting medium of specific density and the particles that have a density less than or equal to that of the extracting medium of specific density can be recovered from a horizonatally rotatable hollow disk or a removable receptacle within a horizontally rotatable hollow disk designed for such purposes while the particles that have a density greater than the extracting medium of specific density form a deposit which can be cycled through the extraction process in an iterative fashion by varying the density of the extracting medium allowing the recovery of discrete particles of differing densities from a test sample.

Abstract: Dictionary-based sequential compression is performed in parallel on input data using multiple cores of a computer system. The compression can be performed by first determining a dictionary size for data compression, followed by determining a block size for partitioning the input data. The block size is greater than the dictionary size. The multiple cores of the computer system then execute multiple threads in parallel, with each thread compressing one block of the input data according to a dictionary-based sequential compression scheme.

Abstract: Techniques for automatically providing a client with access to a virtual machine associated with the client are described herein. According to one embodiment, a message is received by a controller from a client over a network indicating that the client is starting up. In response, the controller causes a connection to be automatically established between the client and a virtual machine (VM) associated with the client once the client has started up. The associated VM may be one of a predetermined VM, a member of a group of VMs that are associated with the client, and a VM selected from a pool of VMs. As a result, a user of the client can instantly access contents provided by the associated VM without having to manually log onto a Web portal in order to select the associated VM to be launched. Other methods and apparatuses are also described.
