Abstract: The present disclosure discloses a method, a device and a system for detecting chromosomal aneuploidy. The method comprises: sequencing at least a portion of a nucleic acid in a sample under test to obtain a sequencing result including reads; aligning the reads to a first reference sequence to obtain an alignment result including specific chromosomes to which the reads are mapped; determining, for a first chromosome, the amount of reads mapped to the first chromosome based on the alignment result; and comparing the number of the reads mapped to the first chromosome with the amount of reads in a negative control mapped to the first chromosome to determine the number of the first chromosome. When the method is employed to detect chromosomal aneuploidy, the detection results acquired have relatively high sensitivity and accuracy.

Abstract: The use of magnetic fields in the production of porous articles is generally described. Certain embodiments are related to methods of producing porous articles in which magnetic fields are applied to an emulsion to align emulsion droplets. In some embodiments, after the emulsion droplets have been aligned, the emulsion droplets and/or the medium surrounding the emulsion droplets can be removed to leave behind a porous article. According to certain embodiments, polyvinyl alcohol can be used, for example, to stabilize the emulsion droplets and/or bind together components of the porous article. In some embodiments, water-soluble liquid alcohol can be used, for example, to stabilize the suspension of electronically conductive material within a phase of the emulsion.

Abstract: The present invention is generally related to separators for use in lithium metal batteries, and associated systems and products. Certain embodiments are related to separators that form or are repaired when an electrode is held at a voltage. In some embodiments, an electrochemical cell may comprise an electrolyte that comprises a precursor for the separator.
