Abstract: Social relationships are detected between a plurality of users. A set of user activity logs is input, where these logs originate from one or more network services and cover a prescribed period of time. Each of the logs originates from a particular one of the services and includes a structured data stream that records each interaction that each of one or more of the users has with the particular one of the services. This structured data stream includes a timestamp specifying when this interaction occurred, and a public network identifier specifying a network address from which this interaction occurred. The set of user activity logs is then analyzed to detect a prescribed kind of social relationship between the users. A data structure is then generated that identifies the users between whom the prescribed kind of social relationship is detected, and the data structure is output.

Abstract: In one aspect, methods of treating cancerous tissue are described herein. In some embodiments, a method of treating cancerous tissue comprises inducing necrotic cell death in cancer stem cells in vivo during hyperthermic treatment of the tissue, wherein inducing necrotic cell death comprises positioning nanoparticles adjacent to the cancer stem cells and irradiating the nanoparticles with electromagnetic radiation resulting in membrane damage to the cancer stem cells.
