Abstract: A method for detecting an object includes obtaining an original image of a road through a sensor by performing an image capturing operation; extracting a region of interest (ROI) including a first target pixel point from the original image, in which the first target pixel point is a pixel point in the original image corresponding to a position on the road that is farthest from the sensor; and generating an object detection result by performing object detection on the ROI.

Abstract: The present invention discloses a method for separating and purifying ?2-macroglobulin from Cohn Fraction IV precipitation, in which Cohn Fraction IV precipitation is treated by ammonium sulfate precipitation, zinc ion affinity chromatography, gel filtration, and ultrafiltration and concentration sequentially and thereby ?2-macroglobulin is obtained finally. With the method provided in the present invention, purified ?2-macroglobulin plasma protein that has a clinical application value is obtained, the Cohn Fraction IV precipitation is changed from a discarded material into a valuable material, and plasma is utilized comprehensively. In addition, the method is easy and simple to use, easy to scale up, and suitable for separation and purification of ?2-macroglobulin at a large scale.

Abstract: A method, an apparatus, and a storage medium are provided for ending video communication. The method includes: detecting whether a first end button is clicked by a user during the video communication between the electronic device and a counterpart device; sending network failure prompt information to a counterpart device when detecting that the user clicks the first end button; sending a disconnection request to the counterpart device to disconnect video communication with the counterpart device.

Abstract: An artificial cervical vertebrae composite joint is composed of two upper and lower fixing members disposed vertically symmetrically, a cervical vertebrae body member, and two connection members, the cervical vertebrae body member being connected between the fixing members through the connection members. The fixing members each have an L shape and comprise a front wing part and a base part. A locking screw hole is formed in the front wing part, and a skidproof groove provided with an inverted tooth and a protrusion is disposed on a middle portion of the base part. A bone grafting hole is transversely disposed through a middle portion of the cervical vertebrae body member, and two cavities are disposed on both upper and lower sides of the cervical vertebrae body member at an axial center of the cervical vertebrae body member to mount the connection members.

Abstract: A transportation platform is provided for using in the stern berth of a container ship to stack nonstandard containers/combined containers. The transportation platform includes a frame with a width corresponding to the ISO standard container width, at least one fixing corner fitting group arranged on the bottom surface of the frame, in which each fixing corner fitting group includes four bottom corner fittings which are arranged according to the corner fitting arrangement for the ISO standard containers, a plurality of top corner fittings arranged on the top surface of the frame, which can be combined into at least one stacking corner fitting group, each stacking corner fitting group has four 2×2 arrayed top corner fittings with a predefined space between each other in length direction, corresponding to the corner fitting space in length direction for the stacked nonstandard containers or combined containers.

Abstract: A transporting platform and a transporting module composed of plurality of transporting platforms, for stacking non-standard containers on standard containers or standardized transporting equipment. The transporting platform includes a pair of transverse beams and a pair of longitudinal beams arranged between the transverse beams. Each of the transverse beams includes: at least one top fitting, arranged on the upper part of the transverse beam for fitting the bottom corner fitting of the non-standard container; and a pair of bottom corner fittings, arranged on the lower part of the transverse beam, and having a center distance therebetween corresponding to the center distance between the corner fittings along the width direction of the standard container.
