Abstract: A tubular end to end coupling structure includes a first inclined tube having a first inclined surface, a second inclined tube having a second inclined surface, and a coupling structure. The first inclined tube and the second inclined tube are connected by the coupling assembly. The coupling assembly includes a plurality of first convex teeth, tooth grooves, second convex teeth and second tooth grooves. The first convex teeth are engaged in the second tooth grooves, and the second convex teeth are engaged in the first tooth grooves. A first protrusion having a through hole is formed at the first inclined surface, a second protrusion having a through hole is formed at the second inclined surface, a first sidewall hole is formed in the first inclined tube, and a second sidewall hole is formed in the second inclined tube.

Abstract: Embodiments of the present disclosure provide a method for generating an information assessment model, a method for determining the usefulness of comment information, apparatus, electronic device, and computer-readable medium.

Abstract: A method, an apparatus, a computer device and a readable medium for knowledge hierarchical extraction of a text are disclosed. The method comprises: performing word segmentation on a designated text to obtain a word list, the word list including at least one word arranged in a sequence in the designated text; analyzing part-of-speech of each word in the word list in the designated text, to obtain a part-of-speech list corresponding to the word list; predicting a SPO triple included in the designated text according to the word list, the part-of-speech list and a pre-trained knowledge hierarchical extraction model. By the technical solutions, the SPO triple included in any designated text however loose its organization and structure is may be accurately extracted based on the pre-trained knowledge hierarchical extraction model. Compared to the prior art, the efficiency and accuracy of knowledge hierarchical extraction may be effectively improved.

Abstract: A bath massage chair includes a pillow, a back support configured to support a torso of the user when the user is seated in the bath massage chair, and a seat coupled to the lower portion of the back support. The pillow includes a pillow massage system and a pillow heating element configured to heat the pillow. The back support includes an upper portion coupled to the pillow and a lower portion opposite the upper portion, a back massage system configured to massage the torso of the user, and a back heating element configured to heat the back support. The seat is configured to support a lower body of the user when the user is seated in the bath massage chair. The pillow massage system, pillow heating element, back massage system, and back heating element are operably coupled to a controller.

Abstract: The present invention provides a monoclonal antibody that specifically binds to human-derived procalcitonin and application thereof. The present invention also provides a hybridoma cell line secreting the monoclonal antibody and having an accession number of CGMCC No. 10417, and a method for preparing an antibody against procalcitonin by using a procalcitonin mutant antigen as the immunogen.

Abstract: A stator fixing structure includes a tube and a fixing member. The tube has an outer surface, and both a stator set and the fixing member are fitted around the tube in a bottom-up sequence. The fixing member has a main body, which has a contact surface and an engaging unit. The engaging unit is circumferentially extended from the main body towards a center of the main body to form a plurality of free ends to tightly press against the outer surface of the tube. The contact surface is axially tightly in contact with the stator set to prevent the stator set from sliding.
