Abstract: Disclosed is a system and method for managing user interactions with a client device. The method comprises receiving from a telecommunication network, connected to the client device, a session request; processing the session request to determine relay information for routing the session request; transmitting the session request to a trained virtual agent based on the relay information, wherein the trained virtual agent is configured to process the session request to generate a command signal; and transmitting the command signal, via a private exchange mechanism, to the client device to establish the session for user interaction, wherein the data transmission between the client device and the trained virtual agent is based on a predefined protocol.

Abstract: A multimodal PET (positron emission tomography)/MRI (magnetic resonance imaging) contrast agent, a process of synthesizing said PET/MRI contrast agent, and a pharmaceutical formulation comprising said PET/MRI contrast agent are disclosed. The PET/MRI contrast agent comprises a magnetic signal generating core, and a coating portion formed at least partially over a surface of said magnetic signal generating core, wherein the coating portion comprises a plurality of layers, including an inner layer having a functionalized surface, and an outer layer in the form of a radionuclide electrolessly plated layer formed on said functionalized surface.

Abstract: A method of purifying a plurality of metal oxide particles produced from a synthesis process comprising the step of washing a plurality of metal oxide particles in a first solvent composition comprising of at least one aliphatic ether, and at least one flocculant. In one embodiment, the plurality of metal oxide particles are iron oxide particles produced from a thermal decomposition synthesis process between an iron-oleate complex and oleic acid in 1-octadecene, wherein the first solvent composition comprises a 1:1 (vol/vol) ratio of an aliphatic ether in the form of diethyl ether and a flocculant in the form of methanol. The washed iron oxide particles are further washed in a second solvent composition comprising a 1:1 (vol/vol) ratio of hexane and ethanol, and then finally dispersed in hexane. The resulting iron oxide particles find use as a contrast agent for magnetic resonance imaging (MRI) or as magnetic particles in magnetic separation, magnetism-directed targeting or magnetism-induced heating.

Abstract: Techniques for representating, managing and storing data related to an organization are provided. An identity management system is disclosed that is configured to manage, represent and store data related to an organization. The identity management system reads data pertaining to an organization from a directory and generates a data model of the organization. The identity management system performs operations to manage the data related to an organization using the data model. The operations include adding logical organizations to the data model and defining user-membership policies associated with entities and logical organizations in the data model. The operations may further include identifying policies to be applied to the users of the organization. In some embodiments, the operations include re-assigning a logical organization and its associated user membership policies to different entities within in the data model while maintaining user-membership policies associated with the logical organization.
