Abstract: The present invention relates to a knitting technology for a circular knitting machine for single jersey-laminated cut pile cloth. A looping process mainly makes an improvement on a motion track of a lower disc assembly of a knitting mechanism for the circular knitting machine. The knitting mechanism comprises the following action steps: a first path: casting on with a half cross stitch and cutting; a second path: casting on and hooking; a third path: casting off, taking back a hook, and hanging wool yarn; a fourth path: after a lower disc completes wool yarn hanging, preventing a needle from casting off; a fifth path: enabling an upper disc to hang the yarn, and enabling the lower disc to hang ground yarn for the first time; a sixth path: enabling the lower disc to hang the ground yarn for the second time; and a seventh path: replacing a knitting hook, wherein the replaced knitting hook is circulated according to the first path to the sixth path of the original knitting hook; the original knitting hook is circulated according to the first path to the sixth path of the current knitting hook; other components of an upper disc assembly and the lower disc assembly are all circulated according to the first path to the sixth path; and the twelve working paths of the upper disc assembly and the lower disc assembly form a working cycle. The present invention can replace an original technology that the reverse side of a cut loop pile product needs glue compounding.

Title: Molecular analyses using long cell-free fragments in pregnancy
Inventor: LO YUK-MING DENNIS
IPC: C12Q1/68
Filed: 2021-02-05
Abstract: Methods and systems described herein involve using long cell-free DNA fragments to analyze a biological sample from a pregnant subject. The status of methylated CpG sites and single nucleotide polymorphisms (SNPs) is often used to analyze DNA fragments of a biological sample. A CpG site and a SNP are typically separated from the nearest CpG site or SNP by hundreds or thousands of base pairs. Finding two or more consecutive CpG sites or SNPs on most cell-free DNA fragments is improbable or impossible. Cell-free DNA fragments longer than 600 bp may include multiple CpG sites and/or SNPs. The presence of multiple CpG sites and/or SNPs on long cell-free DNA fragments may allow for analysis than with short cell-free DNA fragments alone. The long cell-free DNA fragments can be used to identify a tissue of origin and/or to provide information on a fetus in a pregnant female.
