Abstract: A bicycle rear-wheel drive mechanism comprises a fixed shaft, a hollow toothed disc shaft, a wheel shaft, a sprocket shaft, an end cap and pin posts, the hollow toothed disc shaft is composed of a shaft cylinder and a toothed disc arranged at one end of the shaft cylinder, the toothed disc is provided with an array of semi-circular slots located at the edge of the disc body; in this design, the structure is stronger, the torque transmitted is greater, and the driving ability is stronger; replacing the original ball bearings used in bicycles with standardized tapered roller bearings allows the mechanism to be adjusted to the optimal axial and radial positions after installation, while also improving sealing performance and durability.

Abstract: The present invention refers to the field of flue gas purification, which discloses a method and apparatus for capturing carbon dioxide and producing sulfuric acid by sodium bisulfate; using a three-format electrodialysis apparatus to convert the desulfurized by-product NaHSO4 into H2SO4 while capturing CO2 in the flue gas in the cathode chamber. Under the action of electric field drive and ion exchange membrane, HSO4? enters the anode chamber to generate H2SO4 and is concentrated, and Na+ enters the cathode chamber to generate NaOH; the flue gas containing CO2 to be treated is introduced from the cathode chamber and absorbed by NaOH. The invention provides a simple, green, and economic proceeding method to capture the carbon dioxide in the flue gas during the comprehensive utilization of sodium bisulfate solution, which is of better environmental benefits and improvement of the flue gas treatment technology and reducing the pressure of desulfurization gypsum treatment.

Abstract: The present invention relates to a method in a first User Equipment (UE) served by a radio base station (RBS) of a wireless network, for uplink power control at Multiple User Multiple-Input-Multiple-Output (MU-MIMO) scheduling. The method comprises obtaining a power adaptation parameter for use in uplink transmission power control when the first UE is scheduled to be in pair with a second UE, or is scheduled to be de-paired from the second UE. The method also comprises receiving an indication from the radio base station to use the obtained power adaptation parameter in uplink transmission power control, and adapting an uplink transmission power based on the obtained power adaptation parameter and the received indication. The present invention also relates to the corresponding method in the RBS, and to the UE and the RBS.

Abstract: A detection method of nucleic acid is provided. The method includes: providing nucleic acid to be tested, making the nucleic acid to be tested react under asymmetric PCR conditions with a pair of primers for target nucleic acid amplification, DNA polymerase, adenine deoxyribonucleotide, guanine deoxyribonucleotide, cytosine deoxyribonucleotide and thymidine deoxyribonucleotide in a PCR buffer solution, mixing the reaction product and liquid that contains probe molecules, and judging whether the nucleic acid to be tested contains the target nucleic acid by observing the obtained mixture color or color change. A kit is also provided that can be used in the nucleic acid detection by the said method. Application of the method and the kit in inspection and quarantine is also provided. The method is a quick and easy, sensitive and a specific detection method of nucleic acid with direct observation using naked eyes. The method does not need additional equipment.

Abstract: The present invention relates to an RBS of a wireless network and to a method in the RBS for MU-MIMO scheduling. The method comprises estimating (410) a throughput gain of a paired scheduling relative to an unpaired scheduling for a UE pair comprising a first UE and a second UE, and for each of the first and the second UEs individually. The method comprises when the UEs are initially unpaired, to schedule (420) the first UE in pair with the second UE when the estimated throughput gain for the UE pair is above a first threshold, and when the estimated throughput gain is positive for each of the first and second UEs. Furthermore, the method comprises when the first UE is initially paired with the second UE, to schedule (430) the first UE de-paired from the second UE when the estimated throughput gain for the UE pair is lower than a second threshold, or when the estimated throughput gain is negative for either the first or the second UE.

Abstract: The present invention relates to an RBS of a wireless network and to a method in the RBS for link adaptation at MU-MIMO scheduling. The method comprises scheduling (410) a first UE in pair with a second UE, and predicting (420) a signal to noise and interference value for each of the first and second UE as paired. The method also comprises using (430) the predicted signal to noise and interference values for performing link adaptation for the first and second UE.
