Abstract: The ends of cell-free DNA fragments may be used for analysis of a biological sample. In some embodiments, DNA from a urine sample may be analyzed. 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. The density of ends of fragments in certain regions may also be used in classifying the level of a condition. Additionally, DNA fragments may show a periodic pattern with the amount of DNA fragments corresponding to a length of the overhang. The periodicity may be analyzed to determine properties of a biological sample. Jagged ends may also be analyzed with a technique that avoids trimming overhanging 3? ends of a double-stranded DNA.

According to the method, a timbre feature of a speech to be matched is obtained by analyzing a spectral feature of the speech to be matched, and then a target sample audio is determined from at least one sample audio based on a similarity between the timbre feature of the speech to be matched and a timbre feature of the at least one sample audio, where a timbre of the target sample audio matches the timbre of the speech to be matched.

Abstract: A three-dimensional displacement compensation method is provided. The method includes an obtaining step, a transforming step, a first determining step, a first calculating step and a compensating step. The obtaining step includes obtaining a current image of a measured element captured by a microscopic thermoreflectance thermography device. The transforming step includes two sub-steps. One sub-step uses Fourier transform to calculate a reference image to obtain a first result, and the other sub-step uses Fourier transform to calculate the current image to obtain a second result. The first determining step includes determining a peak point coordinate and a fitting diameter of a point spread function of an optical system of the device. The first calculating step includes calculating a three-dimensional displacement of the position to be compensated relative to the reference position. The compensating step compensates the position to be compensated.
