Abstract: The present disclosure provides data processing methods and apparatuses related to LiDAR technologies. In an implementation, a method includes: performing k detection sweeps by using an original detection window to obtain a first set of detection data as a result of the k detection sweeps, wherein k is a positive integer, determining, based on the first set of detection data, a position of an echo pulse at an arrival time point within the original detection window, adjusting, based on the position of the echo pulse, a detection window, performing n detection sweeps by using the adjusted detection window to obtain a second set of detection data as a result of the n detection sweeps, wherein n is a positive integer, and determining, based on the first set of detection data and the second set of detection data or based on the second set of detection data, at least one of a distance or a reflectivity of an object.

Abstract: Methods, devices, and computer-readable storage media for LiDAR ranging are provided. In one aspect, a ranging method for a LiDAR includes: acquiring multiple frames of detection data of a three-dimensional environment; predicting, based on at least part of previous k frames of the detection data, a position where an obstacle is located in the three-dimensional environment during (k+1)th detection, k being an integer and k?1; when performing the (k+1)th detection, changing, based on predicted position information of the obstacle, a detection window for at least one point on the obstacle; calculating ranging information of the at least one point only based on echo information within a range of the changed detection window.

Abstract: The invention discloses the application of a ?-N-acetylhexosaminidase (HaHex74) from Haloferula sp. in the synthesis of human milk oligosaccharides. The invention provides the use of HaHex74 protein or related biological materials thereof in any one of the following: synthesizing human milk oligosaccharides; synthesizing Lacto-N-triose II and/or Lacto-N-neotetraose; the HaHex74 protein having the amino acid sequence shown in SEQ ID No. 2 is derived from Haloferula sp. The ?-N-acetylhexosaminidase HaHex74 disclosed by the invention possesses high-level expression, excellent hydrolysis properties and transglycosylation activity, which may make it potentially useful in the production of human milk oligosaccharides.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for detecting system errors. One of the methods includes collecting an event log for the execution that identifies automated interactions with the application performed by an application testing agent; storing the event log in one or more content storage devices; storing event tracking data captured by a third party system during the automated interaction; comparing the first parameter types with the second parameter types to determine whether expected parameter types from the first parameter types are included in the second parameter types; comparing the corresponding first parameter values with the corresponding second parameter values for the same parameter type to determine whether the corresponding values are the same; and detecting a software error in one or more of the application, the third party system, or the event collection apparatus.
