Abstract: Systems and methods are disclosed for cryptographic signing of content requests. One method includes receiving, at a content network, a content request from a publisher website, the publisher website purporting to be associated with a publisher domain. At the content network, a public key may be received associated with the publisher domain. At the content network, at least one policy may be received associated with the publisher domain. It may be determined whether the content request comprises a cryptographic signature. If it is determined that the content request does not comprise a cryptographic signature, content may or may not be provided to the publisher website according to the policy from the publisher domain. If it is determined that the content request comprises a cryptographic signature, the cryptographic signature of the request may be validated using the public key.

Abstract: A method and system for managing and organizing objects in a virtual workspace is disclosed. The method and system display a plurality of objects and containers on the virtual workspace. The objects and containers are assigned to corresponding layers. The method and system receive user input for changing the corresponding layer of one or more of the objects and containers, recursively fit test each of the layers for an overlap between the one or more of the objects and containers and each container assigned to each layer based on the user input, incorporate the one or more objects and containers into a target container assigned to a target layer when the overlap exceeds a predetermined threshold, and assigns the one or more of the objects and containers to a background layer when the overlap fails to exceed the predetermined threshold in the fit testing.

Abstract: A multi-rate, burst-mode, photon-counting receiver can communicate at data rates up to 10.416 Mb/s over a 30-foot water channel. With added attenuation, the maximum link loss is 97.1 dB at ?=517 nm. In clear ocean water, this equates to link distances up to 148 meters. For ?=470 nm, the achievable link distance in clear ocean water is 450 meters. The receiver incorporates soft-decision forward error correction (FEC) that supports multiple code rates to achieve error-free performance. A burst-mode receiver architecture provides robust performance with respect to unpredictable channel obstructions. The receiver can detect the data rate on-the-fly and adapts to changing levels of signal and background light. The receiver updates its phase alignment and channel estimates every frame, allowing for rapid changes in water quality as well as motion between transmitter and receiver.

Abstract: Methods, computer-readable media, and systems for providing disease management. In one implementation, a system develops a treatment recommendation for a patient based on patient data. The system may receive patient data, execute a basic model of the physiological system of the patient to generate a modified model for the patient based on the patient data, perform a statistical analysis of the patient data to detect data excursions of the parameter values; use the modified model to determine factors causing the data excursions; and use the model to develop a treatment recommendation to ameliorate negative effects of the disease.

Abstract: A method is proposed for calculating a line performance, or stability, measure for a telephone line. Various physical parameters associated with the line, such as insulation resistance, capacitance and DC voltages, are measured. The values for each of the parameters are compared to expected values, which are based on historical values measured for that line. Individual performance measures for each parameter are calculated based on the difference between the actual and expected values, normalised by the deviation of that parameter. The deviation accounts for general fluctuations across all the lines. A weighting value is also applied, based on knowledge of values relevant to the good operation of lines. The deviation effectively gives a scaling, and the weighting gives a context to the measured values for a single line. The individual performance measures are summed to get the final performance measure for the line.
