Abstract: A method for identifying a hardware device in an operating system and a computer apparatus are provided. The method includes determining a unique index identifier of a hardware device, and establishing a mapping relationship between the unique index identifier and a device number of the hardware device. The method also includes obtaining the unique index identifier of the hardware device, in response to a status change of a hardware interface. Further, the method includes according to the mapping relationship, obtaining and allocating the device number to the hardware device to enable an access to the hardware device according to the device number of the hardware device.

Abstract: The present invention generally relates to systems and methods for imaging or determining nucleic acids, for instance, within cells. In some embodiments, the transcriptome of a cell may be determined. Certain embodiments are directed to determining nucleic acids, such as mRNA, within cells at relatively high resolutions. In some embodiments, a plurality of nucleic acid probes may be applied to a sample, and their binding within the sample determined, e.g., using fluorescence, to determine locations of the nucleic acid probes within the sample. In some embodiments, codewords may be based on the binding of the plurality of nucleic acid probes, and in some cases, the codewords may define an error-correcting code to reduce or prevent misidentification of the nucleic acids. In certain cases, a relatively large number of different targets may be identified using a relatively small number of labels, e.g., by using various combinatorial approaches.
