Publication number: 20200090814Abstract: The present disclosure relates to exemplary embodiments of method, computer-accessible medium, system and software arrangements for, e.g., Cancer Hallmark Automata, a formalism to model the progression of cancers through discrete phenotypes (so-called hallmarks). The precise computational model described herein includes the automatic verification of progression models (e.g., consistency, causal connections, etc.), classification of unreachable or unstable states (e.g., “anti-hallmarks”) and computer-generated (individualized or universal) therapy plans. Exemplary embodiments abstractly model transition timings between hallmarks as well as the effects of drugs and clinical tests, and thus allows formalization of temporal statements about the progression as well as notions of timed therapies. Certain exemplary models discussed herein can be based on hybrid automata (e.g., with multiple clocks), for which relevant verification and planning algorithms exist.Type: ApplicationFiled: November 20, 2019Publication date: March 19, 2020Applicant: New York UniversityInventors: Loes Olde LOOHUIS, BHUBANESWAR MISHRA, ANDREAS WITZEL

Patent number: 9832098Abstract: A method for connecting, by a central control unit (CCU), a booting switch to a network. The network includes switches controlled by the CCU using control data packets that are transmitted via communications paths in the network. User packets are transmitted through the network using the same communications paths. A switch uses forwarding rules stored in a pipeline to forward packets in the network. A local port in each switch provides access to the pipeline. The paths in the network for the control data packets are established by storing forwarding rules configured by the CCU in the pipelines of the switches. At least one switch contains a connecting port via which the booting switch is connected to the network. The forwarding rules in the booting switch are stored by the CCU using a temporary path, which contains the existing path and a connecting path.Type: GrantFiled: January 9, 2013Date of Patent: November 28, 2017Assignee: TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)Inventors: Jan Scheurich, Dirk Kampmann, Christoph Meyer, Andreas Witzel

Patent number: 9716652Abstract: A method for handling, by a ring node of a network having a ring topology, a data transfer of data packets through the network via which the data packets are transmitted to their destination node, wherein each ring node has two neighboring ring nodes. The method includes detecting data packets of an incoming data transfer received from a non ring node to be transmitted through the network to their destination node. Furthermore, a ring direction is added to the data packets of the incoming data transfer, the indication indicating in which direction the data packets of the incoming data transfer are passed through the network having the ring topology. The data packets of the incoming data transfer are forwarded to one of the two neighboring ring nodes based on the added indication.Type: GrantFiled: March 5, 2012Date of Patent: July 25, 2017Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Dirk Kampmann, Christoph Meyer, Andreas Witzel

Patent number: 9614876Abstract: The present invention proposes a solution for providing IMS services to users having circuit-switched controlled terminal being not adapted to provide IMS services to the users. In particular, it is proposed, in order to allow IMS to take the full call and service control, to place a user agent being responsible for the user ported to the IMS in a new node type called Mobile Access Gateway Control Function (MAGCF). This new node combines the logical functionality of a cellular switching center and the logical functionality of IMS. Further it is proposed to enhance a user's register, like HLR, to provide also information about the availability of a MAGCF node and about whether a particular user is enabled to use the MAGCF functionality.Type: GrantFiled: October 21, 2005Date of Patent: April 4, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Andreas Witzel, Ralf Keller

Patent number: 9584574Abstract: The invention proposes several methods for codec handling. In specific, methods involving providing a supported codec list of a Call Control Server are described. A node receives information, whether a terminal supports a wideband codec, wherein the information is received in call set up signaling from the terminal of the subscriber. Furthermore, configuration information is retrieved, whether a Radio Access Node supports the wideband codec. Additionally, information is retrieved, whether a media gateway supports the wideband codec, wherein the information is either provided by the operator or retrieved from the media gateway (MGW1, MGW2, MGWx). The information is analyzed and in response to the analysis a supported codec list is provided. Furthermore, alternative embodiments and devices adapted for the methods are disclosed.Type: GrantFiled: March 2, 2006Date of Patent: February 28, 2017Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Andreas Witzel, Dirk Kampmann
