  • Patent number: 8916205
    Abstract: Biodegradable polymeric nanoparticles comprising an inner core formed of a photodynamic agent capable of being activated to generate cytotoxic singlet oxygen are prepared. These nanoparticles have anti-cell proliferation activity and are useful in treating both cancerous and non-cancerous conditions including actinic keratosis, psoriasis and acne vulgaris. Preferably, the photodynamic agent is a hypocrellin B derivative while the polymeric nanoparticle comprises polyglycolic acid, polylactic acid or poly(lactide-co-glycolide). Hypocrellin-comprising nanoparticles are demonstrated to be activated by light or hydrogen peroxide.

  • Publication number: 20140280870
    Abstract: Systems and methods for preventing web services from using sensitive data in customizing web pages for a user. In one embodiment, a protection system is implemented between the user and the web service. The protection system identifies past interactions of the user with the web service, identifies text in the past interactions between the user and the web service, and identifies subjects discussed in the text. The protection system then communicates with the user to determine which of the subjects are sensitive to the user, and deletes a history stored by the web service for the user that relates to the sensitive subjects.

  • Publication number: 20140181978
    Abstract: A method and computer product are presented for identifying Internet worm propagation based upon changes in packet arrival rates at a network connection. First, unsolicited (i.e., packets that were not requested by the receiver) traffic is separated from solicited traffic at the network connection. The unsolicited traffic arrival patterns are monitored and analyzed for any changes. Once changes in the unsolicited traffic arrival patterns are detected, the changes are mathematically analyzed to detect growth trends. The presence of growth trends that follow certain key characteristics indicate whether the changes are due to worm propagation.

  • Patent number: 8619779
    Abstract: Various embodiments relate to a Cloud Data Center, a system comprising the Cloud Data Center, and a related method. The Cloud Data Center may include a logical customer edge router to send packets between addresses in a private enterprise network and addresses in a logical network within a cloud network. The logical network may have resources, known as virtual machines, allocated to the private enterprise network and may share a common IP address space with the private enterprise network. A directory at the Cloud Data Center may correlate the enterprise IP addresses of virtual machines with a cloud IP address and a location IP address within the logical network. The Cloud Data Center may double encapsulate packets with two specified headers, a cloudIP and locIP header, when sending a packet to a destination in the logical network.

  • Patent number: 8250210
    Abstract: A method of balancing user registration lifetimes in a network is disclosed for smoothing the load of the registration server. The method of balancing user registration lifetimes in a network includes providing an initial registration lifetime for a registration request that is calculated using the time of the request and the previous history of registration requests, and in a particular embodiment, using the cumulative distribution function of the history of registration requests. The method of balancing user registration lifetimes in a network is particularly useful for handling spikes in registration traffic, and can accommodate user-specified variable lifetimes, as well dynamic user arrivals and departures. It provides effective load balancing over time for a single server, at the expense of a constant factor additive load per user, which can be amortized to near zero over the long run.
