Abstract: Provided are a method and a kit for constructing a simplified genomic library. The method comprises: performing a non-specific amplification on a whole genome with a first pair of primers to obtain random amplified fragments; performing a specific amplification on the random amplified fragments with a second pair of primers to obtain the simplified genomic library.

Abstract: Provided are a method and device for analyzing a sequencing data result, and a sequencing library construction and sequencing method. The method for analyzing the sequencing data result includes: a sequencing data result of a sequencing library is acquired (S101), the sequencing library including a plurality of mixed samples, each of the samples corresponding to a label sequence combination, and different samples corresponding to different label sequence combinations, wherein each label sequence combination includes a plurality of label sequences, the sequencing data result comprises a sequencing fragment set obtained by sequencing the plurality of mixed samples, and the sequencing fragment set includes a plurality of disordered sequencing fragments; a label sequence combination of each of the sequencing fragments is determined (S102); and a sample corresponding to each of the sequencing fragments is determined according to the label sequence combination of each of the sequencing fragments (S103).

Abstract: A limited mode dispersion compensating optical fiber comprising four core areas, with the first area exhibiting a peak refractive index designated nc1, a second core area surrounding the first core area exhibiting a peak refractive index nc2, a third core area surrounding the second core area exhibiting a peak refractive index nc3, a fourth core area surrounding the third core area exhibiting a peak refractive index nc4 and a cladding area surrounding the fourth core area. The fourth core area is designed to have a low enough refractive index so as not to support additional modes. The limited mode dispersion compensating optical fiber supports the LP02 mode, and exhibits average dispersion more negative than −250 ps/nm/km.
