Abstract: A computing system including two or more controllers, a universal asynchronous receiver-transmitter (UART) multiplexer, and a combinational logic circuit is provided. The two of more controllers include a first controller and a second controller. The first controller is configured to provide a first status signal and a first select control signal, and the second controller is configured to provide a second status signal and a second select control signal. The UART multiplexer is configured to provide UART output from at least a first UART input and a second UART input based on a UART select signal. The combinational logic circuit is configured to determine the UART select signal is one of the first select control signal or the second select control signal based at least in part on the first status signal and the second status signal.

Abstract: A method for treating infection of group A Streptococcus (GAS) includes grouping a patient infected with GAS into an invasive infected candidate. An antibiotic is then administrated to the invasive infected candidate to treat the infection of GAS. Moreover, the patient is grouped into the invasive infected candidate when a first detected level, determined by ex vivo contacting a first biopsy obtained from the patient with a FSBM recombinant protein having an amino acid sequence set forth as SEQ ID NO: 10, is smaller than 0.6.
