Abstract: The present invention relates to phosphonated Rifamycins, and methods of making and using such compounds. These compounds are useful as antibiotics for prophylaxis and/or the treatment of bone and joint infections, especially for the prophylaxis and/or treatment of osteomyelitis.

Abstract: In some embodiments, authentication, confidentiality, and privacy are enhanced for a wireless network of cognitive radios by encryption of network management and control messages as well as data traffic, thereby protecting information pertaining to node identification, node location, node-sensed incumbent transmissions, CRN frequency channel selections, and such like. During initial network registration, a temporary ID can be issued to a node, and then replaced once encrypted communication has been established. This prevents association of initial, clear-text messages with later encrypted transmissions. Elliptic curve cryptography can be used for mutual authentication between subscribers and the base station. ECC-based implicit digital certificates can be embedded in co-existence beacons used by CRN nodes to coordinate use of frequency channels, thereby preventing denial of service attacks due to transmitting of falsified beacons.

Abstract: There is provided salts and polymorphs of sitagliptin, processes for the preparation thereof, and pharmaceutical compositions comprising the same.

Abstract: Techniques are disclosed that allow for resource allocation during situations requiring co-existence in cognitive radios. Even under situations of bandwidth scarcity, the techniques allow various users to be guaranteed quality of service (QoS) by proper distribution and allocation of resources. The techniques allow wireless communication systems to operate in a normal mode and a co-existence mode. In the co-existence mode of operation, sub-frame creation, sharing and zone formation schemes are implemented that enable the existing underlying frame structure to remain intact and inter-operable with the legacy systems and at the same time, provide a guaranteed QoS. The zones effectively create partitions in space, time and frequency, which result in interference avoidance and allow various users in neighboring cells to communicate on the same frequencies.

Abstract: There is provided a compound, which is dehydroabietylamine salt of rosuvastatin. Also provided are processes for making rosuvastatin calcium that include formation of dehydroabietylamine salt of rosuvastatin.

Abstract: A distributed decision support system is described for use in the area of problem discovery and capacity planning for database applications. The use of data navigation, particularly drill down, roll up, and pivot for application management tasks are described. The system presents data collected from components of an application server system by various cartridges to users in a way that facilitates the identification of problems in the application server system and provides for an efficient way to do capacity planning of such systems.

Abstract: Various cognitive communications system architectures and their corresponding Protocol Reference Models (PRMs) are disclosed. Such PRMs incorporate a Cognitive Plane in addition to conventional Data and Management Planes. The additional Cognitive Plane functionality may include, for example, spectrum sensing, spectrum management, geolocation, and security functions. The Cognitive Plane may further include a Policy Engine and a Learning and Reasoning Module. In some embodiments, Management Plane functions may be effectively combined to form a database of primitives (and their respective values) called a Management Information Base (MIB). In addition, techniques are provided by which various components of cognitive and non-cognitive, as well as mesh-enabled and non-mesh-enabled nodes in a network, inter-operate with each other. The architectures allow a Spectrum Manager (or Signal Space Manager) to combine information from various network layers (e.g.

Abstract: A method of producing a playlist of music for a personal music station comprising the steps of assigning a artist block rating to each of a plurality of predefined artist blocks, using the artist block rating to produce an artist rating for each artist in the artist block, generating a list of artists, wherein the number of times each artist appears in the list is related to the artist rating for each artist, randomly selecting artists form the list of artists, producing a prioritized list of songs for each of the randomly selected artists, and selecting songs from the prioritized list of songs for inclusion in a playlist. The playlist can be subsequently edited to create a playlist having a less than a first predetermined number of songs by each of the artists for broadcast within a predetermined time period and having less than a second predetermined number of adjacent songs by each of the artists. A method of distributing songs on a personal music station using the playlist is also included.
