Abstract: Disclosed are a pharmaceutical composition and method for relieving/eliminating morphine-induced analgesic tolerance. The pharmaceutical composition includes a therapeutically effective amount of a short peptide and morphine as active ingredients, and a pharmaceutically-acceptable carrier. The short peptide is a peptide consisting of an amino acid sequence shown in SEQ ID NO: 1 or a pharmaceutically-acceptable salt thereof. In the method, the short peptide and morphine are administered to a subject simultaneously; or the short peptide is injected to the subject followed by administration of the morphine; or a pharmaceutical composition including the short peptide and morphine is administered to the subject.

Abstract: A camera pose information detection method, includes collecting a plurality of images by means of a multi-lens camera, and determining a road surface region image based on the plurality of images; and projecting points in the road surface region image onto a camera coordinate system, so as to obtain camera pose information.

Abstract: A method for denoising magnetostrictive guided wave detection signals to improve detection accuracy. The method includes forming a matrix A by using the signals; performing a singular value decomposition on the matrix A to obtain a singular matrix B including a plurality of eigenvalues; setting eigenvalues in the singular matrix B that are smaller than the median to zero to obtain a matrix C; performing an inverse transformation of the singular value decomposition on the matrix C to obtain a matrix D; and determining the denoised signals according to the matrix D.

Abstract: A method for processing magnetostrictive guided wave detection signals, including: 1) obtaining an analysis signal by capturing an original magnetostrictive guided wave detection signal; 2) performing band-pass filtering on the analysis signal to obtain a signal, and initializing i to 0; 3) obtaining a group of signals x(i), x(i+1), . . . , x(i+M?1) using a rectangular window with a width of M; 4) forming a matrix A; 5) performing singular value decomposition on the matrix A to obtain a singular matrix B; 6) setting eigenvalues in the matrix B smaller than the median to 0 to obtain a matrix C, and performing inverse singular value transformation on the matrix C to obtain a matrix D; 7) recovering a group of processed signals from the matrix D and calculating energy z of the group of processed signals; and 8) setting i to (i+1) and repeating steps 3)-7) until i=N+1?M.

Abstract: The present invention relates to a bicycle folder with a self-locking device, which can lock the handle of the folder, consists of front and rear folding leaves of the folder and a quick release handle. The quick release handle is mounted on the front folding leaf of the folder, and tightly locked on the front and rear folding leaves of the folded folder after they are folded. A locking buckle is provided on said quick release handle, and a locking tongue is provided on a bicycle tube. The locking tongue is locked in the locking buckle of the quick release handle which can tightly lock the folder. Said locking tongue is composed of a position limit handle and a handle shaft, and has a certain clearance from the bicycle tube.
