Abstract: Technology described herein includes a method that includes obtaining an image of a fluid of a microfluidic analysis system. The microfluidic analysis system includes or receives a container that contains the fluid for measurement of analyte or quality determination. A region of interest (ROI) is identified based on the image. The ROI is a set of pixel values for use in the measurement of the analyte or the quality determination of the fluid, fluidic path, or measuring system. Identifying the ROI includes: determining an alignment of the container of the fluid with the imaging device based on the image, and identifying the ROI based on information about the measurement of the fluid or based on information about non-analyte features of the fluid. An analysis of the image of the fluid is performed using the set of pixel values of the ROI.

Abstract: The invention provides a method of identifying a modified cytosine residue in a polynucleotide. The method includes the steps of reducing and deaminating a 5-methylcytosine residue within the polynucleotide and sequencing the polynucleotide, such that the location of the modified cytosine residue can be identified. The invention also provides a method of identifying a 5-methylcytosine residue, a 5-carboxylcytosine residue or a nucleotide in a polynucleotide. The method involves treating the polynucleotide with a radical initiator. The presence of the 5-methylcytosine residue, 5-carboxylcytosine residue or nucleotide can be identified as a residue such as thymine detected by sequencing of the treated polynucleotide.

Abstract: The invention provides a method for labeling a nucleic acid comprising N6-methyl adenine. The method comprises forming an alpha-amino radical on the N6-methyl group of N6mAde, and capturing the alpha-amino radical with a radical acceptor comprising a nitrosopyridyl group. The presence of N6mAde in a nucleic acid may then be established by detection of the labeled nucleic acid, or the labeled nucleic acid may be extracted or further modified using the label. Also provided is a method for mapping the position of N6mAde within a target nucleic acid, and probe molecules and kits for use in the method.

Abstract: Application consistent dataset recovery using a cognitive control plane is provided. Sequence and timestamp of snapshots of volumes in a consistency group across heterogenous storage components corresponding to an application are recorded to facilitate operational recovery of application consistent datasets for the application. The cognitive control plane establishes a framework to manage, monitor, analyze, and update the consistency group and metadata to facilitate application consistent data recovery. A set of snapshots needed for the operational recovery of the application consistent datasets for the application is identified by mapping the sequence and timestamp of the snapshots of the volumes in the consistency group across the heterogenous storage components corresponding to the application in response to the computer determining that the operational recovery of the application consistent datasets for the application has been requested.

Abstract: Data is migrated from a source storage device to a destination storage device using tape media. Both the source storage device and the destination storage device utilize disk drives to store data. A portion of data is detected migrating to the tape media. Metadata of the portion of data is changed to identify the portion of data as residing on the tape media. A prefetch command for the portion of data is detected. It is determined that the portion of data is stored on the tape media. In response to determining that the portion of data is stored on the tape media, the prefetch command is executing without recalling the portion of data to the disk drives. Instead, the portion of data is read directly from the tape media.
