Upon a trigger, such as a determination to scale a server, a scaled server may be spun up and an identifier of the scaled server provided to a first (existing) server. The first server sends the identification of the second server, and session state information for each of the connections between the first server and the request router, to the request router. For each of the connections, the request router establishes a new connection between the request router and the second (scaled) server, and replays the session state information for the connection to the second server. The request router then routes traffic between each existing client connection (e.g., the same existing client connection which carried traffic delivered to the first server) and the corresponding new connection to the second server. |

Session establishment using path change
As described herein, a router signals a source device to establish a new stateful communication session with a destination device by changing a network path used by traffic associated with the session. In one example, a router forwards traffic of a first stateful routing session established by the source device along a first path. In response to determining that that the first path should not be used, the router forwards a packet of the first session along a second path. The destination device recognizes the change in path, which causes the destination device to reject the packet, which in turn causes the source device to establish a second stateful routing session. The router forwards subsequent traffic of the second stateful routing session along the second path. |

Adaptive synchronous protocol for minimizing latency in TDD systems
Systems and methods are presented that offer significant improvements in the performance of time division duplex (TDD) systems by utilizing an adaptive synchronous protocol. Conventional TDD systems are limited because data is transmitted during discreet and limited intervals of time, and because TDD transceivers may not simultaneously transmit and receive for reasons of insufficiently separated frequencies and limited receiver selectivity. Typically, TDD systems have significant latency due to the time to change from transmission to reception and the propagation delay time. By synchronizing the master nodes and the one or more remotes and by scheduling the traffic loads between these nodes, remote nodes may begin transmitting before the master node is finished with its transmission, and vice versa. This method reduces latency and improves the frame efficiency. Further, the frame efficiency may improve as the distance from the master node to the remote node increases. |

Risk monitoring scores
A user interface for clinical personnel provides selectable views of a plurality of medical risk scores. Questions whose answers are needed for calculation of those risk scores are asked in a question and answer area of the user interface, which allows some questions to be answered based on real time patient physiological data streams that are overridable by user provided answers. Where multiple risk score calculations require answers to the same question, the user provided answer may be supplied as an answer to the corresponding question for each risk score, rather than requiring the user to answer multiple times. Sparklines may be provided with the displayed risk scores to show trends in the risk score values, and may be updated in real time based on real time physiological data streams. The display of risk scores may visually distinguish between risk scores that have been validated and those are based on unvalidated answers to the questions. |

Method for acquiring and for altering a configuration of a number of objects in a procedure room and corresponding device
The disclosure relates to a method for acquiring and for altering a configuration of a number of objects in a procedure room for planning and for collision avoidance during a medical procedure, wherein each object is represented by a virtual model, including a physical model of the object and a safety zone around the physical model. The physical model represents the configuration of the object and the safety zone represents a collision-prevention area for a movement of any of the objects during a medical procedure. The virtual models of the objects are placed at a position in a virtual model of the procedure room. Additionally, the configurations of the physical models during the medical procedure are computed and the configuration of the physical model of the corresponding object is altered when a collision during the movement is determined. The disclosure further relates to a device for executing the method. |

Systems and methods for analyzing longitudinal health information and generating a dynamically structured electronic file
A method for generating an electronic file associated with health care professionals (HCPs). The method includes receiving health information from a covered entity computing system and a file generation request from a user computing device. The method further includes matching HCP information with the health information and determining one or more statistical values based on at least one of the matched HCP information or the matched health information. The method further includes generating the electronic file including the one or more statistical values and at least a portion of the matched HCP information and providing the file to the destination address of the file generation request. The electronic file is generated as the file type identified by the file generation request, and is structured based on at least one of the file generation request or the file destination. |

Key note
Methods, computer systems, and computer storage media are provided that enables clinicians to create and interact with snapshots of critical clinical/non-clinical information that is readily accessible in future visits. Initially, an indication to create a key note corresponding to a clinical note of a patient encounter for a patient is received. A selection of a key note section that will be associated with the key note is also received. Upon the clinical note being signed, the key note is created and saved. Upon receiving a request from a user, a key note window is provided in a user interface. The user interface enables the user to expand a header corresponding to a particular key note to display details associated with the corresponding encounter. A hyperlink to original summary notes from which the particular key note was created may be provided by the user interface. |

System and method for increasing synthesized protein stability
A computer-implemented method of training a neural network to improve a characteristic of a protein comprises collecting a set of amino acid sequences from a database, compiling each amino acid sequence into a three-dimensional crystallographic structure of a folded protein, training a neural network with a subset of the three-dimensional crystallographic structures, identifying, with the neural network, a candidate residue to mutate in a target protein, and identifying, with the neural network, a predicted amino acid residue to substitute for the candidate residue, to produce a mutated protein, wherein the mutated protein demonstrates an improvement in a characteristic over the target protein. A system for improving a characteristic of a protein is also described. Improved blue fluorescent proteins generated using the system are also described. |

Global redundant column select implementation for boundary faults in a memory device
An electronic device includes memory banks and repair circuitry configured to remap data from the memory banks to repair memory elements of the memory banks when a failure occurs. The repair circuitry includes a logic gate configured to receive an output from a memory bank of the memory banks, receive a failure signal indicating whether a corresponding memory element has failed, and transmit the output with a value of the output is based at least in part on the failure signal. The repair circuitry also includes error correction circuitry configured to receive the output via the logic gate and a multiplexer configured to receive the output from the memory bank, receive a repair value, and selectively output the output or the repair value from the repair circuitry as an output of the repair circuitry. |
