    Abstract: Disclosed is a conjugate for gene transfer, which is capable of being used for treatment of incurable diseases, comprising an oligonucleotide intended to be transferred into target cells and a hydrophilic polymer, wherein an end of the oligonucleotide is covalently conjugated to the hydrophilic polymer. Also, the present invention discloses polyelectrolyte complex micelles formed from such a conjugate and a cationic polymer or cationic peptide. Such polyelectrolyte complex micelles can effectively transfer oligonucleotides as therapeutic agents into target cells, making it possible to obtain desired activities of the delivered oligonucleotides in target cells even when the micelles are clinically applied at a relatively low concentration. Therefore, the conjugate and the polyelectrolyte complex micelle are very useful in basic life science research and the medical field.

    Abstract: The present invention relates to an apparatus for rejecting images in a receiver.The apparatus of the present invention relates to an apparatus for rejecting image signals in a receiver of a direct conversion structure and comprises a signal mismatch compensation unit configured to detect gain error and phase error between an In-phase (I) signal and a Quadrature (Q) signal received through the receiver, to reject image signals existing in the I and Q signals, and to output a result. The signal mismatch compensation unit detects the gain error and the phase error using an adaptive step method of reducing the step size of the gain error and the phase error step by step whenever the gain error and the phase error are converged.According to the present invention, high image rejection ratio is achieved and the adaptation time taken to obtain a high image rejection ratio is reduced simultaneously. Further, a bad influence of the DC offset on the image rejection ratio can be prevented by removing DC offset signals in a digital structure, accordingly, error can be accurately estimated.

    Abstract: The present invention relates to an algorithm that retrieves only k data elements having the largest (or smallest) key values from a dataset (i.e., top-k results) in a time linearly proportional to the size of the dataset. The proposed method using the algorithm finds the top-k results using a k-sized min (or max) heap structure that maintains candidate elements of the top-k results by scanning all data elements in the dataset only once. In other words, the present invention provides a linear-time top-k sort method that finds top-k results in a time linearly proportional to the size of the dataset (i.e., O(n) time complexity), while conventional sort algorithms for finding top-k results cannot find the top-k results in a time linearly proportional to the size of the dataset (i.e., at least O(n log n) time complexity).
