    摘要: A method for manufacturing an amorphous multielement metal oxide hydroxide film includes: A liquid mixture is formed by dissolving an oxidizing agent selected from a group consisting of potassium permanganate, potassium chromate, potassium dichromate and potassium ferrate, and a reducing agent in a solvent. The oxidizing agent forms an oxometallate anion having a first metal atom with a first valence number. The reducing agent forms a metal cation having a second metal atom with a third valence number. An amorphous multielement metal oxide hydroxide film is deposited on a substrate by soaking the substrate in the liquid mixture. The amorphous multielement metal oxide hydroxide film includes a multielement metal oxide hydroxide having the first metal atom with a second valence smaller than the first valence number and the second metal atom with a fourth valence number larger than the third valence number.

    摘要: A waveguide division multiplexer and demultiplexer includes a first-stage Mach-Zehnder interferometer (MZI) and two second-stage MZIs. The first-stage MZI includes two input ends and two output ends, in which one of the inputs is configured to receive an input optical beam with a first center wavelength and a second center wavelength, and the output ends are configured to respectively transmit first-stage output optical beams respectively with the first center wavelength and the second center wavelength. One input terminals of the second-stage MZI are configured to respectively receive the first-stage output optical beams, and one output terminals of the second-stage MZI are configured to transmit second-stage output optical beams with the first and second center wavelengths, respectively. Each second-stage MZI is configured in cross-state condition.

    摘要: A method for signal optimization between a user equipment and a reconfigurable intelligence surface includes a phase optimization step having: generating at least one modified phase combination in the state that a performance index of a current phase combination is smaller than a preset performance threshold value; evaluating whether a corresponding performance index of the modified phase combination is not smaller than the preset performance threshold value or evaluating whether the performance index of the modified phase combination is larger than the corresponding performance index of the current phase combination, to determine an optimized phase combination, enabling a corresponding performance index to be not smaller than the preset performance threshold value or not smaller than the performance index of any modified phase combination in the phase optimization step; and replacing the current phase combination by the optimized phase combination to form an updated current phase combination.

    摘要: A real number sine/cosine wave basis function transform circuit includes a window segmentation element, a first transform element, a second transform element and a root-sum-square (RSS) element. The window segmentation element is provided to segment an in-phase output signal and a quadrature output signal to output an in-phase window signal and a quadrature window signal. The first and second transform elements are provided to transform the in-phase window signal and the quadrature window signal using a real number sine/cosine wave basis function to obtain a first transformed signal and a second transformed signal, respectively. The RSS element is provided to calculate an RSS value of the first and second transformed signals and output a real number sine/cosine wave basis function transformed signal.

    摘要: The present invention provides a method of sugar-guided modifying a glycosylated polypeptide. First, a boronic acid group of a probe molecule and a sugar group of the glycosylated polypeptide form a first covalent bond. Next, an alkyne group of a modifying group and an azide group of the probe molecule form a second covalent bond by adding a promoter. As a result, the modifying group can be close to the glycosylated polypeptide. Then, the modifying group can bind to a nucleophilic residue that is near the sugar group, through a nucleophilic addition reaction. The method of the present invention can selectively modify a given site with the guidance of the sugar group.
