The application provides a new pollutant intelligent identification method based on high-resolution mass spectrometry non-target screening, which comprises the following steps: pretreatment, generation of a feature list and calculation of feature quality scores; automatic spectrum analysis on high-quality features; multi-dimensional matching with a suspect database to calculate a comprehensive score; double-threshold shunting based on the comprehensive score; low-matching features enter an unknown new pollutant discovery process, and high-matching features directly enter joint reasoning; joint reasoning integrates double-path molecular descriptors cross-validation, Bayesian multi-evidence fusion and candidate structure sorting; and finally, multi-level credibility scores are outputted to generate a report. The double-threshold automatic feature shunting mechanism based on feature quality scores and suspect comprehensive matching scores is adopted, the processing paths of known substances and unknown substances are automatically distinguished in a single pipeline, the problem that known substance identification and unknown substance discovery are mutually separated and need manual intervention for shunting in the prior art is solved, and the workload of manual screening is significantly reduced.

This invention discloses tumor antigen epitope peptides derived from embryonic stem cells and their applications. The tumor antigen epitope peptides comprise one or more sequences selected from those shown in SEQ ID NO:1-10. This invention also provides antitumor pharmaceutical compositions comprising the aforementioned tumor antigen epitope peptides. This invention screens for highly expressed tumor antigens and their epitope peptides by comparing genes co-expressed by embryonic stem cells and tumor cells. Animal experiments have demonstrated that the extended peptides of these epitope peptides can stimulate specific cytotoxic T lymphocyte immune responses, stimulate the secretion of high levels of IFN-γ, and inhibit tumor growth.

The present application relates to the technical field of space target detection, and discloses a star cluster cooperative space target search and orbit determination method, which comprises the following steps: a ground computing center generates prior guidance data of a space target and injects the star cluster; a wide field satellite node performs sky domain search according to the prior guidance data, extracts a two-dimensional observation error covariance through dimension reduction and shift superposition processing, and sends an inter-satellite data frame containing the covariance and instantaneous pose to a narrow field satellite node; the narrow field satellite node receives the inter-satellite data frame, performs reference alignment and state extrapolation in combination with a prior distance error variance and an earth-centered inertial coordinate system, and generates an extrapolated three-dimensional error ellipsoid; the narrow field satellite node generates a boresight maneuver trajectory according to the error ellipsoid to realize physical locking of the target; and the star cluster performs state convergence based on a cross-line-of-sight network to complete cooperative orbit determination. The present application overcomes the problem of limited single-satellite field of view and lack of depth data, and realizes effective capture and orbit determination of a multi-satellite cooperative space target.

This utility model discloses a multi-directional adjustable cotton topping device, relating to the field of cotton planting technology. It includes a support base, a support frame fixed to the top of the support base, a fixed frame slidably connected to the inner wall of the support frame, a fixed plate fixed to one side of the fixed frame, and a housing fixed to one side of the fixed plate. A driving component for adjusting the topping height is provided on the top of the support frame. The advantages of this utility model are: each set of mounting frames is equipped with an independent electric push rod, and through the sliding cooperation of the connecting frame and the limiting frame, the height of the cutter head can be adjusted individually, adapting to the problem of uneven cotton plant growth. The adjustment component drives the horizontal movement of the mounting frames on both sides, achieving the effect of adjusting the distance between the mounting frames. This allows the topping device to quickly switch to different row spacings, avoiding missed or repeated operations due to mismatched row spacing, and improving the versatility of the device.
