Abstract: A protocol has been developed for genetically engineering an attenuated pathogen such as the influenza virus that can grow in cells without interferons but has suppressed growth in cells with the interferons. The protocol comprises systematically identifying immune evasion functions on the pathogen's genome, then eliminating the immune evasion functions while maintaining a certain replication fitness of the pathogen. The resulting attenuated pathogen causes a strong immunologic response and can be used in a live attenuated vaccine.

Abstract: A method for automating network function virtualization (NFV) using a modular NFV framework involves subscribing, by a control module of a network, to a key of a state store of the network. The state store includes stored data objects and unique keys. Each of the stored data objects is associated with one of the unique keys. The key is one of the unique keys. A notification is received at the control module from the state store. The notification is associated with the key. The control module reads a data object, associated with the key, from the stored data objects in the state store in response to the notification, and the control module modifies a network traffic flow of the network through two or more software network functions of the network based on the data object.

Abstract: A blockchain is used to track chain of custody associated with devices and user entities associated with those devices. In an embodiment, an identity engine traverses a blockchain to determine one or more transactions associated with a device and, in some cases, one or more users of that device. Based at least in part on the content of an authentication or provisioning request and that of the chain of custody, the identity engine provisions the device for a given user.

Abstract: Systems and methods are described for authenticating parties who communicate via unauthenticated channels. A user authentication verification service receives a request to confirm the identity of a party who communicates via an unauthenticated channel. The user authentication verification service may identify a computing device associated with the claimed user identity, and may determine that the computing device (or an application installed on the computing device) can be used to authenticate the user. The user authentication verification service may thus transmit a push notification or other request to the computing device to request authentication from the user that the party claims to be or represent. The user authentication verification service may then receive information from the computing device, confirm that the information authenticates that the party is the user (or is acting on behalf of the user), and authorize communication via the unauthenticated channel.

Abstract: The technology described herein includes a system and/or a method for global hypothesis tracking. In some examples, a method generates one or more paired segments based on track data representing kinematic data of target objects. Each paired segment includes a list of tracks incompatible with the paired segment, which are tracks sharing common track data, and a likelihood score. The method generates a transition probability between each pair of the paired segments based on the list of tracks incompatible with the paired segment and the likelihood score associated with each paired segment. The method further generates one or more multi-segment tracks based on the one or more paired segments also based on the transition probability between each pair of the paired segments.

Abstract: Embodiments of a target-tracking system and method of determining an initial target track in a high-clutter environment are generally described herein. The target-tracking system may register image information of first and second warped images with image information of a reference image. Pixels of the warped images may be offset based on the outputs of the registration to align each warped images with the reference image. A three-frame difference calculation may be performed on the offset images and the reference image to generate a three-frame difference output image. Clutter suppression may be performed on the three-frame difference image to generate a clutter-suppressed output image for use in target-track identification. The clutter suppression may include performing a gradient operation on a background image to remove any gradient objects.

Abstract: A method may include subscribing each of a plurality of users to receive native-format geospatial information from a data source. The method may also include receiving native-format geospatial information from the data source. The method may further include analyzing native-format geospatial information and previously-rendered geospatial data file fragments to determine whether to update one or more previously-rendered geospatial data file fragments. The method may additionally include translating native-format geospatial information into geospatial data file fragments in response to a determination to update one or more previously-rendered geospatial data file fragments, and storing such geospatial data file fragments.

Abstract: A voice and image e-mail transmitter device with an external camera attachment that is designed for the emergency and surveillance purposes is disclosed. The device converts voice signals and photo images into digital format, which are transmitted to the nearest voice-image message receiving station from where the digital signal strings are parsed and converted into voice, image, or video message files which are attached to an e-mail and delivered to user pre-defined destination e-mail addresses and a 911 rescue team. The e-mail also includes the caller's voice and personal information, photo images of a security threat, device serial number, and a GPS location map of the caller's location. The digital signal data may be recorded and transmitted within few seconds. The victim's family or police may either check the GPS location map in an e-mail or apply a new GPS based people tracking system of the present invention to search for a missing victim.

Abstract: A voice-image e-mail transmitter device that is designed for emergency and surveillance purposes is disclosed. This device converts voice signals and picture images into digital format, which are transmitted to the nearest voice-image message receiving station from where the digital signal strings are parsed and converted into audio and image files, such as “.wav” and “.jpeg” files. The generated files are attached to e-mails and delivered to pre-defined e-mail addresses and a 911 rescue team. The message information includes the caller's voice, pictures of a potential attacker, time the message was sent and received, device serial number, and approximate location of the caller. An external camera and microphone may be connected by wire or wireless means to a CPU element in a base portion of the voice-image e-mail transmitter device. Data may be recorded and sent within seconds by simply pressing and releasing a push button on the device.
