Abstract: A method of detecting lung nodules in an anterior posterior x-ray radiograph comprising the steps of: generating candidate regions in image showing changes in contrast above a threshold level, and eliminating false positives by eliminating edges assignable to organs by: identifying edges; categorizing and eliminating rib edges; categorizing and eliminating lung tissue edges, and categorizing and eliminating blood vessels.

Abstract: A method and system for aggregating contact information of contacts from multiple contact sources is provided. The aggregation system collects contact information for a user from various contact sources. The aggregation system stores the collected content information in a contact data store. The aggregation system may also store an indication of the contact source of the collected contact information. The aggregation system provides a user interface through which the user may search the contact information of the contact data store to find contact information of contacts that are collected from the different contact sources. The aggregation system allows a user to add a contact to a real-time contact list to enable real-time communications with that contact.

Abstract: A method of identifying nodules in radiological images, said method comprising: (a) obtaining a radiological image; (b) selecting a sub-image centered around a candidate location; (c) dividing the sub-image into a rectangular array of cells; (d) calculating absolute values of Intensity Differences id(k) according to a Fractional Brownian Motion (FBM) calculation equation: id ( k ) = [ ? x = 0 N - 1 ? ? y = 0 N - k - 1 ? ? I ? ( x , y ) - I ? ( x , y + k ) ? 4 ? N ? ( N - k ) + ? y = 0 N - 1 ? ? x = 0 N - k - 1 ? ? I ? ( x , y ) - I ? ( x + k , y ) ? 4 ? N ? ( N - k ) + ? x = 0 N - 1 - k ? ? y = 0 N - k - 1 ? ? I ?

Abstract: A method and system for providing extended presence information defined by third parties and for detecting when the extended information has changed significantly is provided. An extensible presence service defines a presence document for a publishing user having a section reserved for extended information provided by one or more third parties and publishes the presence document to a presence server. Subscribing users send subscription requests to the presence server to receive updates when the presence document for the publishing user changes. When the extended information provided by the third party is updated, the third party updates the extended information and indicates whether the change to the extended information is significant. Next, the presence server sends the updated presence document containing the updated extended information to subscribed users.
