Abstract: The invention provides a chip including a package substrate, at least one subunit, and a radio frequency chip. Each subunit includes an end-fire antenna disposed on an upper surface of the package substrate. The end-fire antenna is electrically connected to the radio frequency chip through a feed line.

According to the millimeter-wave antenna chip provided in this application, the end-fire antenna may be lifted to the upper surface of the package substrate of the chip by using stacked metal via holes of the package substrate, and a height of the end-fire antenna relative to a peripheral component may be increased by using a thickness of the package substrate.

Abstract: Described are methods for the high-throughput discovery and genotyping of nucleotide polymorphisms in DNA, including single nucleotide polymorphism (SNPs) and short deletions and insertions. These methods take advantage of the fact that differences in DNA sequence result in the differential presence of restriction endonuclease digestion sites. Approaches involve isolation of short DNA fragments (“tags”) near restriction endonuclease sites. The presence of one (or two) of these tags indicates that a site was present. Regions of DNA with a restriction site in only one individual create an opportunity for primer extension to produce labeled material, which can be assayed on a platform that employs a collection of nucleic acids. Efficient variant detection microarrays and bead libraries are provided that contain genomic tags with different representations between two populations, so that most elements in the collection of nucleic acids contain a SNP between populations of interest.

Abstract: A vehicle capable of driving on land, air or water comprises of a fuselage (1), a main engine or a main motor, and a power control and transmitting system. A main shaft (2) is provided at two sides of the fuselage. Blade sleeves (6) are fixed to the main shafts. Blade handles (7) capable of spinning around own axes are mounted on the blade sleeves. Blades are fixed to the blade handles. Blade open-close devices are installed on the fuselage and/or on the main shafts to control the blades to rotate relative to the blade sleeves and the main shafts. The blade open-close device is a mechanism that can open and close the blades once a cycle of rotating along with the main shaft. When opened, blades' broad flat surfaces are parallel or generally parallel with the main shafts. When closed, the blades' broad flat surfaces are perpendicular or generally perpendicular to the main shafts.

Abstract: This disclosure provides methods for detecting and localizing DNA mutations by DNA microarray. In various embodiments, the described methods include use of restriction endonuclease(s) and/or mismatch-recognition nuclease(s) to detect and/or localize mutations. In one representative method, reference and target DNA are digested using one or more restriction endonucleases, resultant DNA strands are labeled (e.g., using a DNA polymerase), and the labeled mixture of DNAs is hybridized to a microarray. In another representative method, reference and target DNA are denatured and annealed to form a mixture containing heteroduplex DNA, one or more mismatch-recognition nuclease(s) are used to nick or cleave at least a portion of the heteroduplex DNA, resultant DNA strands are labeled (e.g., using a DNA polymerase) and the labeled mixture of DNAs is hybridized to a microarray.

Abstract: Described herein are methods for the high-throughput discovery and genotyping of nucleotide polymorphisms in DNA, including single nucleotide polymorphism (SNPs) and short deletions and insertions. These methods take advantage of the fact that differences in DNA sequence result in the differential presence of restriction endonuclease digestion sites. Differences can be detected between individuals, or the relative presence detected in a population. Provided approaches involve isolation of short DNA fragments (“tags) near restriction endonuclease sites. The presence of one (or two) of these tags indicates that a site was present. Distinguishable labeling of tags from two individual or populations allows comparative presence of these sites to be assayed on a platform that employs a collection of nucleic acids. Other approaches depend on the differential presence of restriction endonuclease sites, but involve mixing genomic DNA from the two individuals.
