Techniques for embedding fabric address information into locally-administered ethernet media access control addresses (MACs) and a multi-node fabric system implementing the same
Techniques for embedding fabric addressing information within Ethernet media access control (MAC) addresses is disclosed herein and allows a multi-node fabric having potentially millions of nodes to feature Ethernet encapsulation without the necessity of a lookup or map to translate MAC addresses to fabric-routable local identifiers (LIDs). In particular, a locally-administered MAC address may be encoded with fabric addressing information including a LID. Thus a node may exchange Ethernet packets using a multi-node fabric by encapsulating each Ethernet packet with a destination MAC address corresponding to an intended destination. As the destination MAC address may implicitly map to a LID of the multi-node fabric, the node may use an extracted LID value therefrom to address a fabric-routable packet. To this end, a node may introduce a fabric-routable packet encapsulating an Ethernet packet onto a multi-node fabric without necessarily performing a lookup to map a MAC address to a corresponding LID. |

Thin and uniform silver nanowires, method of synthesis and transparent conductive films formed from the nanowires
Highly uniform and thin silver nanowires are described having average diameters below 20 nm and a small standard deviation of the diameters. The silver nanowires have a high aspect ratio. The silver nanowires can be characterized by a small number of nanowires having a diameter greater than 18 nm as well as with a blue shifted narrow absorption spectrum in a dilute solution. Methods are described to allow for the synthesis of the narrow uniform silver nanowires. Transparent conductive films formed from the thin, uniform silver nanowires can have very low levels of haze and low values of ΔL*, the diffusive luminosity, such that the transparent conductive films can provide little alteration of the appearance of a black background. |

Double containment nuclear power reactor with passive cooling and radiation scrubbing
A nuclear power reactor which includes passive cooling and radiation scrubbing. The reactor includes a first containment member which is buried in the ground. A second containment member is positioned in the first containment member and has a reactor vessel therein. The discharge side of the reactor vessel is connected to a heat exchanger which drives a turbine which drives a device such as a generator. A source of water is provided which gravity feeds cooling water to the interior of the first containment member in the event of reactor overheating or over-pressurization. A radiation scrubber is provided for scrubbing radiation which may be in the first containment member or the second containment member. |

System and method of determining financial loss for worker's compensation injury claims
A system and method is implemented to provide a construction of three separate timelines for comparison and analysis including a query to a historical accurate database. One or more data sets are compared to a high accuracy database that contains reviewed and accurate historical impairment data. An analysis of the historical data can facilitate the output of a temporary impairment rating, apportionment, future care demand of resources and one or more recommendations for the most effective manner to achieve MMI. The collection of outputs are used to create an injury map nexus. |

Automatic clinical report generation
Methods and systems for clinical report generation. One system includes an electronic processor configured to receive a query image and determine a similarity metric for a plurality of medical images, where the similarity metric represents a similarity between the query image and each of the plurality of medical images. The electronic processor is also configured to determine a predetermined number of medical images from the plurality of medical images based on the similarity metric for each of the plurality of medical images. The electronic processor is also configured to rank a plurality of reports, where each of the plurality of reports correspond to one of the predetermined number of medical images. The electronic processor is also configured to generate a clinical report including information extracted from at least one of the plurality of reports based on the ranking of the plurality of reports. |

Unified ecosystem experience for managing multiple healthcare applications from a common interface with context passing between applications
A browser-based, user interface served by a manager application providing for a unified ecosystem experience empowering healthcare users with seamless control over a plurality of different applications and/or websites in a maximized, consolidated and synchronized manner. The manager application includes a user interface with common toolbar controlling a plurality of panels built upon underlying frame data for displaying various applications and/or websites in a consolidated view. The information in the panels can be contextually linked such as via an informational update in one panel triggering a message for a relevant update to be performed in adjacent panels in the user interface manager application. Therefore, a uniform user experience with consistent look-and-feel is provided despite using separate applications and/or websites. |

Machine learning models for automated request processing
A computerized method of automatically processing a medical imaging record using a machine learning model includes training a machine learning model prediction engine with historical medical imaging records, receiving a first medical imaging record from a first system, applying a set of specified approval criteria to the first medical imaging record to determine a provisional outcome, and in response to the provisional outcome being negative, selectively identifying an exception to the provisional outcome in response to input received by a user interface. In response to the exception not being identified, the method includes inputting a feature vector based on the first medical imaging record to the machine learning model prediction engine to generate a likelihood estimate, comparing the generated likelihood estimate to a target threshold, and in response to the generated likelihood estimate being greater than the target threshold, transmitting a signal indicating approval to the first system. |
