  • Patent number: 11121104
    Abstract: A conductive interconnect structure includes a contact pad; a conductive body connected to the contact pad at a first end; and a conductive layer positioned on a second end of the conductive body. The conductive body has a longitudinal direction perpendicular to a surface of the contact pad. The conductive body has an average grain size (a) on a cross sectional plane (Plane A) whose normal is perpendicular to the longitudinal direction of the conductive body. The conductive layer has an average grain size (b) on Plane A. The conductive body and the conductive layer are composed of same material, and the average grain size (a) is greater than the average grain size (b).

  • Patent number: 11119087
    Abstract: The invention provides a method for establishing a separable regeneration system for verifying regeneration effect between two antioxidants, which belongs to the field of regeneration effect of antioxidants. According to different solubilities of two antioxidants, lipid-soluble antioxidant is first combined into PE film, and water-soluble antioxidant is dissolved into deionized water and a separable regeneration system where antioxidants can contact with other but not dissolve in each other is formed. This method compares the differences of change of antioxidant capacity in aqueous phase with and without lipid-soluble antioxidant so that to judge whether the added lipid-soluble antioxidant has regeneration effect on aqueous-soluble antioxidant. The present invention effectively verifies the regeneration effect between different antioxidants, and has advantages of simple operation, less interference factors, intuitive and high efficiency.

  • Publication number: 20210265007
    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.

  • Patent number: 11091794
    Abstract: Systems and methods for using determination of base modification in analyzing nucleic acid molecules and acquiring data for analysis of nucleic acid molecules are described herein. Base modifications may include methylations. Methods to determine base modifications may include using features derived from sequencing. These features may include the pulse width of an optical signal from sequencing bases, the interpulse duration of bases, and the identity of the bases. Machine learning models can be trained to detect the base modifications using these features. The relative modification or methylation levels between haplotypes may indicate a disorder. Modification or methylation statuses may also be used to detect chimeric molecules.

  • Publication number: 20200056245
    Abstract: Cell-free DNA fragments often include jagged ends, where one end of one strand of double-stranded DNA extends beyond the other end of the other strand. The length and amount of these jagged ends may be used to determine a level of a condition of an individual, a fractional concentration of clinically-relevant DNA in a biological sample, an age of individual, or a tissue type exhibiting cancer. The jagged end length and amount may be determined using various techniques described herein.
