Abstract: There is provided a method of profiling a microbiotic composition of a sample comprising the nucleic acid molecules of the microbiotic composition, the method comprising a) partitioning the sample in a sufficient number of partitions such that at least a portion of the partitions comprises no more than one nucleic acid molecule of the microbiotic composition; b) contacting the partitions of the sample to a plurality of mismatch-tolerant probes that are capable of binding to the nucleic acid molecules or parts thereof under suitable conditions; c) determining signals generated by each of the plurality of mismatch-tolerant probes in each partition; and d) establishing the microbiotic composition in the sample based on the signals. Also disclosed is a method of determining a health and kits for uses in the methods as described herein.

Abstract: A method and device for controlling a distributed direct current power supply system are provided in embodiments of this disclosure. The method includes: acquiring a direct current busbar current of the distributed direct current power supply system; acquiring, according to the direct current busbar current and a rated capacity of a power conversion unit in the distributed direct current power supply system, a quantity of power conversion units that meets a power requirement of a load; and adjusting, according to the quantity of power conversion units, power conversion units that are turned on in the distributed direct current power supply system. The device is used to implement the method.
