Abstract: The present invention relates to a bioelectrode for increasing abundance of cable bacteria, including an anode, a cathode, and a partition. The anode is horizontally disposed, and the cathode is disposed perpendicular to the anode. The anode and the cathode are separated by using the partition. An objective of the present invention is to provide a method for keeping a high abundance of the cable bacteria in sediments when oxygen content of overlying water is low and even in an anaerobic environment. The method can be further performed in a self-starting manner, and has a potential application prospect in ecological remediation of sediments.

Abstract: The present disclosure relates a method for reducing animal weight, comprising administering to a patient in need thereof a therapeutically or prophylactically effective amount of a mulberry extract. The mulberry extract comprises: 3% to 99% of an alkaloid, 0.2% to 70% of a polysaccharide, 0% to 50% of an amino acid, 0% to 10% of flavone, and 0% to 25% of other components. The mulberry extract of the present disclosure can be used for controlling weight gain, and has a good therapeutic effect on type 2 diabetes with obesity.

Abstract: A generation method of zero watermarking for trajectory data, a detection method of zero watermarking for trajectory data, a generation device of zero watermarking for trajectory data, a detection device of zero watermarking for trajectory data, and a storage medium are provided. The generation method divides a trajectory based on a coordinate system constructed by trajectory feature points of trajectory data into blocks, and then the moment invariants of trajectory in each block are used to construct a watermark sequence, which can achieve copyright protection without modifying the trajectory data. In addition, since the generation method uses moment invariants which can represent overall features of the trajectory to construct the watermark sequence, the generation method has strong stability in the face of common attacks and can resist almost all common types of attacks.

Abstract: An image display method and device are provided. The method is applied to an electronic device having a display screen and a camera. The method includes: detecting a first operation of turning on the camera by a user; displaying a photographing interface on the display screen in response to the first operation, where the photographing interface includes a viewfinder frame including a first image; detecting a second operation of the camera indicated by the user; and displaying a second image in the viewfinder frame in response to the second operation, where the second image is an image obtained by processing N frames of raw images captured by the camera; a neural network model is applied to a processing process, and the neural network model uses an image whose noise is lower than a target threshold as an output objective; and N is an integer greater than or equal to 2.
