Abstract: There is disclosed system for oxygenating a patient in relation to anaesthesia using high flow gas delivery. The system has a flow source, and a controller for determining oxygenation requirements of the patient before or during anaesthesia. A method of oxygenating a patient in relation to anaesthesia using high flow gas delivery is also disclosed. The method determines oxygenation requirements of the patient before or during anaesthesia.

Abstract: Disclosed are methods and systems and computer program products for determining DPB1 expression without the need for rs9277534 (3? UTR) sequence data. Such methods are useful in assessing HLA sequencing submitted to or already in donor databases for matches that will reduce the risk of hematopoietic transplant rejection (i.e., graft vs. host disease).

Abstract: Disclosed are methods and systems for the detection of variants of the SARS-CoV-2 virus that cause COVID-19. For example, disclosed are methods for identifying and/or tracking variants of SARS-CoV-2 comprising: (a) identifying a sample from a subject as positive for SARS-CoV-2 nucleic acid and/or antibodies to SARS-CoV-2; (b) generating a sample-specific SARS-CoV-2 nucleic acid from the sample; (c) performing nucleic acid sequencing on the sample-specific SARS-CoV-2 nucleic acid; and(d) determining whether the nucleic acid sequence comprises a SARS-CoV-2 variant sequence. Also disclosed are systems for performing any portion of the disclosed methods and computer-program products tangibly embodied in a non-transitory machine-readable storage medium, including instructions configured to perform any of the steps of the disclosed methods or run any portion of the disclosed systems.

Abstract: A communication system and method of operating the same that includes, in one embodiment, a transmit filter including a transmit filter capacitor, and a receive filter coupled to the transmit filter. The communication system also includes a switch, coupled to an auxiliary winding of a transformer and to the transmit filter capacitor, configured to alter an impedance of the transmit filter during a receive mode of operation of the communication system. In another embodiment, a transmitter is configured to receive an input data stream, and produce a control signal for a switch-mode power amplifier employing a predetermined data sequence selected by the input data stream thereto.

Abstract: A controllable electrical switch having a power system and switching device for connecting a source voltage to a load. The power system includes a switching regulator to extract energy directly off the non filtered full wave rectified input voltage to minimize the average magnitude of the current when the switching device is in the off-state. For on-state power the controllable electrical switch may include a transformer connected in series with the switching device. The controllable electrical switch and power system may be used to replace a standard two- wire or three-wire wall switch, and may be used over a wide voltage and load power range in a low cost, small package with low power dissipation.
