Abstract: A technique for providing search results may include determining a first entity type, a second entity type, and a relationship type based on a compositional query. The technique may also include identifying nodes of a knowledge graph corresponding to entity references of the first entity type and entity references of the second entity type. The technique may also include determining from the knowledge graph an attribute value corresponding to the relationship type for each entity reference of the first entity type and for each entity reference of the second entity type. The technique may also include comparing the attribute value of each entity reference of the first entity type with the attribute value of each entity reference of the second entity type. The technique may also include determining one or more resultant entity references from the entity references of the first entity type based on the comparing.

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.

Abstract: System and method for determining gain characteristics of a circularly-polarized antenna. The method includes receiving a measured first amplitude of a forward gain between a circularly-polarized antenna probe of a first type and a linearly-polarized standard-gain antenna, a measured second amplitude of a forward gain between a circularly-polarized antenna probe of a first type and a circularly-polarized antenna under test, and a measured third amplitude of a forward gain between a circularly-polarized antenna probe of a second type and the circularly-polarized antenna under test. The method also includes determining a left-hand circularly-polarized gain and a right-hand circularly-polarized gain of the circularly-polarized antenna under test based on the measured first amplitude, the measured second amplitude, the measured third amplitude, and a cross-polarization level of the circularly-polarized antenna probes of the first and second types. The determination may be performed using one or more processors.

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.

The determination may be performed using one or more processors.

Abstract: Various embodiments are directed to using nuclease expression in tissues that influences cell-free DNA end signatures/motifs and size of overhang between DNA strands. Embodiments can identify a nuclease that is being differentially regulated in abnormal cells relative to normal cells. Embodiments can determine that the nuclease preferentially cuts DNA into DNA molecules having: (i) a particular sequence end signature; or (ii) a specified length of overhang between a first strand and a second strand. A parameter can be determined for a biological sample based on an amount of DNA molecules that include an end sequence corresponding to the particular sequence end signature and/or a measured property correlating to the specified length of overhang. The parameter can be used to determine a characteristic of a tissue type, a fractional concentration of clinically-relevant DNA molecules, or a level of abnormality of a tissue type in the biological sample.
