  • Patent number: 10694034
    Abstract: Provided are systems, methods, and media for verifying a commission-based relationship in a communication system. An example method includes generating authorization information by an authorizer that is to be transmitted to a caller and forwarded by the caller to a callee upon a call being initiated between the caller and the callee, in which the authorization information includes at least authorizer identity information, callee identity information, and a caller public key. The method includes signing the authorization information with a private key of the authorizer and transmitting the signed authorization information to the caller. The caller is configured to generate a digital signature via a private key of the caller and transmit the digital signature and the signed authorization information to the callee. The callee is configured to verify the identity of authorizer, caller and callee and event information based on the authorization information.

  • Publication number: 20200176115
    Abstract: The present invention is directed to a system and method for using physiological time-series (PTS) data sampled continuously from patients in the ICU. An algorithm according to an embodiment of the present invention applies statistical modeling and machine learning methods to implement an early warning policy for predicting those patients likely to transition from non-sepsis, early sepsis or sepsis into septic shock. Results demonstrate that the system and method of the present invention can provide higher sensitivity and specificity in this task than any other method reported to date. It provides an advanced early warning of this pending transition with median value 12.5 hours, giving ample opportunity for physicians to intervene to prevent the patient from developing septic shock.

  • Publication number: 20200162574
    Abstract: A system and method for joint dynamic interest request forwarding and dynamic cache placement and eviction and provided within the context of the Named Data Networking (NDN) architecture. The system and method employ a virtual control plane that operates on the user demand rate for data objects in the network, and an actual plane that handles Interest Packets and Data Packets. Distributed algorithms within the virtual plane achieve network load balancing through dynamic forwarding and caching, thereby maximizing the user demand rate that the NDN network can satisfy. A method of congestion control is also provided to achieve optimal network fairness using the VIP framework.

  • Patent number: 10613842
    Abstract: A computer-implemented method includes receiving an initial control flow graph (CFG) describing a project, where the project includes one or more programs. The initial CFG includes a plurality of graph nodes and a plurality of edges connecting the plurality of graph nodes to one another. Based on first profiling data, a first set of one or more graph nodes of the plurality of graph nodes of the initial CFG is selected as a first set of main nodes. The first profiling data describes a first execution history of the project. The initial CFG is simplified by generating a first final CFG, which includes the first set of main nodes and excludes one or more remaining nodes of the initial CFG that are not in the first set of main nodes.
