Abstract:
Disclosed are a LDL-like cationic nanoparticle for delivering a nucleic acid gene with improved transfection efficiency and stability, which is surface modified and re-constructed by mimicking lipid components of a natural LDL, a method for preparation of the same, and a method for delivering nucleic acid genes using the same. The cationic nanoparticle of the present invention could effectively be applied in treatment of cancer that overexpress LDL receptors.
Abstract:
A method of setting a packet transmission path in a wireless communication network and a network apparatus using the same are provided. A method of setting a packet transmission path includes setting N−1 routing regions including at least one node between a source node and a destination node based on a predetermined N number of hops, N denoting an integer greater than or equal to two, and determining a node in each of the routing regions as a relay node based on a channel gain.

PROBLEM TO BE SOLVED: To provide an image sensor capable of achieving images with high quality.SOLUTION: The present invention comprises a charge detection amplifier that amplifies charges detected by a detector and includes an input terminal, an amplification terminal and an output terminal. The charge detection amplifier includes a first capacitor connected between the input terminal and the amplification terminal, a first switching unit connected between the input terminal and the amplification terminal, a second capacitor connected between the amplification terminal and the output terminal, and a second switching unit connected between the output terminal and a reference voltage terminal.
Abstract:
Disclosed is a technology of encoding haptic information on images or decoding haptic information from images. The method of encoding the haptic information on the images according to the present invention includes: generating haptic information; generating encoding target data by using the haptic information and header information associated with the haptic information; and generating an encoded image by encoding the encoding target data by using a least significant bit (LSB) of byte data of each of the original image pixels. As a result, the present invention can simply encode/decode the haptic information while maintaining an original image format.
