Abstract: Contact recommendations based on purchase history are described. A system creates a directed graph of nodes in which at least some of the nodes are connected by directed arcs, wherein a directed arc from a first node to a second node represents a conditional probability that previous users who purchased a first contact also purchased a second contact. The system identifies a set of contacts purchased by a current user. The system estimates a prospective purchase probability based on a historical probability that previous users purchased a specific contact and a related probability that previous users who purchased the specific contact also purchased a contact in the set of contacts, for each candidate contact. The system outputs a recommendation for the current user to purchase a recommended candidate contact based on a corresponding prospective purchase probability.

Abstract: A source device communicates multimedia data to a sink device over a multimedia channel of a multimedia link. The source device comprises an interface to a full duplex control channel of the multimedia link. The source device also comprises first arbitration logic to control transfer of control data with the sink device via the full duplex control channel. The first arbitration logic ignores requests to receive inbound control data from the sink device while the source device is transmitting outbound control data to the sink device. The sink device, on the other hand, comprises second arbitration logic to control transfer of control data with the source device via the full duplex control channel. The second arbitration logic stops transmitting outbound control data via the full duplex control channel responsive to receiving a request to receive incoming control data from the source device.

Abstract: New method of cooling of MRI coil and resonators is disclosed and described. MRI coil designs showed in the disclosure are based solely on the use of copper tube elements filled with liquid nitrogen. Inside the conducting tubes at rf frequency there is no rf electric field, thus the liquid nitrogen presence inside such coils will not have any influence on MRI coil dielectric losses and on the resonant frequency modulation. Liquid nitrogen cooled coils, when in the coil noise regime, demonstrate 2-3 gain of signal-to-noise ratio comparing with room temperature equivalent coils. Methods for making and using both superconducting and normal metal MRI coils and/or arrays in such configurations are also disclosed.
