Abstract: A photosensitive assembly includes a circuit board. The circuit board has a first surface, a second surface opposite to the first surface, and a first through hole extending through the first surface and the second surface. A photosensitive chip is disposed on the second surface. The photosensitive chip has a photosensitive area and a non-photosensitive area connected to the photosensitive area, the non-photosensitive area is electrically connected to one side of the second surface, and the photosensitive area is exposed from the first through hole. A reinforcing plate is disposed on the first surface. A thermal conductive layer is disposed on the photosensitive chip, and the thermal conductive layer includes a silica gel or a metal.

Abstract: A positioning system and a positioning method based on radio frequency identification techniques (RFID) are provided. The positioning system includes in-vehicle devices, RFID readers and a server. The in-vehicle devices each includes a positioning device, an image capturing device and an image recognition module. The positioning device obtains a positioning location. The image capturing device captures a driving image. The image recognition module identifies adjacent vehicles, adjacent license plate information, and road attributes, and calculates relative location information. Each of the RFID readers reads a vehicle tag of one of the vehicles passing by, so as to mark a reference vehicle and generate reference vehicle information. A positioning adjustment module of the server determines whether the target vehicle is a reference vehicle, has been the reference vehicle or is a non-reference vehicle, and adjusts the positioning location of the target vehicle in different ways, accordingly.

Abstract: Methods for isolating K+Hnov genes are provided. The K+Hnov nucleic acid compositions find use in identifying homologous or related proteins and the DNA sequences encoding such proteins; in producing compositions that modulate the expression or function of the protein; and in studying associated physiological pathways. In addition, modulation of the gene activity in vivo is used for prophylactic and therapeutic purposes, such as identification of cell type based on expression, and the like.

Abstract: Nucleic acid hybridization under steady-state conditions is described by a kinetic model in which the intermediate state is assumed to be locally single stranded. An expression was derived that relates nucleic acid secondary structure to the rate of oligonucleotide-RNA hybridization. The model allows the calculation of a rate factor that is proportional to the rate constant for hybridization between complementary nucleic acids and is generally applicable to any RNA molecule with potential utility for rapid identification of sites for antisense attack of mRNA.

Abstract: Nucleic acid hybridization under steady-state conditions is described by a kinetic model in which the intermediate state is assumed to be locally single stranded. An expression was derived that relates nucleic acid secondary structure to the rate of oligonucleotide-RNA hybridization. The model assumes that the hybridization of nucleic acids occurs through an intermediate state in which the region to be hybridized has a single-stranded conformation prior to binding the antisense oligonucleotide. In the derivation, a steady-state condition is assumed. The model is applicable to the steady-state condition in living cells and the initial stage of single-tube hybridization when full-length hybrid has not significantly accumulated and the concentration of nucleation complex is approximately constant. The model allows the calculation of a rate factor that is proportional to the rate constant for hybridization between complementary nucleic acids.
