Abstract: The application discloses a classification method and a system of UAV hyperspectral vegetation species based on a deep learning, where the method includes the following steps: collecting hyperspectral images by a UAV; preprocessing collected hyperspectral images to obtain preprocessed images, and performing a stitching mosaicking preprocessing on the preprocessed images to obtain hyperspectral orthoimages; labeling the hyperspectral orthoimages to obtain a label data set; performing a vegetation index fusion on the hyperspectral orthoimages to obtain vegetation index-hyperspectral orthoimages; constructing a grassland vegetation classification model based on the vegetation index-hyperspectral orthoimages and the label data set, and completing a vegetation species classification by using the grassland vegetation classification model.

Abstract: Provided herein are anti-CD39 antibodies that inhibit the enzymatic activity of human CD39 and methods of using the same.

Abstract: A heat pipe with micro tubes includes of a solid heat conductor provided therein with two or more parallel micro tubes. The micro tubes are filled with a working medium which exchanges heat through phase change. Two ends of the heat conductor are sealed and at least one of the ends is provided with a sealing strip of gradually shrinking shape that is formed from cold welding.

Abstract: An efficient heat sink for solar photovoltaic cells and a combined heat and power generation system include one or more flat plate heat pipes. A front plate surface of the front and back plate surfaces engages with and covers the backplate of the cell plate. A heat exchanger of plate pipe type engages with the cooling portion of backplate surface of the flat plate heat pipe. Heat absorbed by the heat absorption surface of the flat plate heat pipe from the cell plate is dissipated by the heat exchanger through cooling media without affecting combination of the cell plate with a building surface or application of the cell plate as a building component. Therefore, the temperature of the cell plate is prevented from rising, the dissipated heat may be utilized to generate hot water, solar utilization efficiency is improved, and the cost of the solar photovoltaic industry is reduced.
