A biomarker for early diagnosis of diabetes and its application created by the present invention aim to explore the dynamic changes of proinsulin during sugar load and its significance in early identification of pancreatic islet beta cell function decline, that is, to provide a simpler, Effectively indicate the clinical indicators of early reduction of β-cell function, and provide early basis for preventing the occurrence of diabetes.

The invention discloses an early identification method of a glacier lake outburst, comprising the following steps: a. determining the basic glacier data of the outburst glacial lake and surrounding unbursted glacial lakes; b. determining the prerequisites for a glacier lake outburst. The ratio of the vertical height H from the center of mass of the avalanche to the ice lake and the straight-line distance L from the center of mass of the potential avalanche to the ice lake is greater than or equal to 0.125; 1 Greater than the critical water level H of glacial lake outburst 2 ; c. Calculation of glacier comprehensive discriminant factor S for glacial lake outburst; d. When S > 0.53, the risk is high; when 0.38 < S ≤ 0.53, the risk is medium; when S ≤ 0.38, the risk is low. The present invention conducts internal mechanism research on the occurrence degree of glacial lake outbursts through terrain factors, establishes a calculation model for glacial lake outbursts, comprehensively considers the terrain influencing factors of glacial lake outbursts, and accurately divides glacial lake outburst risk areas in a quantitative manner. Strong.

The invention discloses a small-sample named entity recognition method based on data enhancement and active learning. The purpose is to improve the F1 value of the early recognition of unlabeled data by the active learning method, and is effective for various query strategies. The technical solution is to first construct an active named entity recognition system combined with data enhancement; prepare the data set required for training the named entity recognition model. The active learning module, the data labeling module, and the data enhancement module train the named entity recognition model in the named entity recognition module in a multi-round cycle and label and enhance the data. The trained named entity recognition module performs named entity recognition on the text in the test data pool T, and obtains the predicted label sequence. The present invention realizes the effect of rapidly improving named entity recognition when there are few labeled data participating in training in the early stage, so that compared with the original named entity recognition method under active learning, F1 values ​​of various query strategies are all improved.

The invention provides a rice DPS1 gene and encoded protein and application thereof. The sequence of the rice DPS1 gene is shown in the SEQ ID No.2, and the sequence of the encoded protein is shown in the SEQ ID No.1. It is found that the top spikelet of the mutant of the rice DPS1 gene is dry up and necrotic before flowering, and the middle spikelet closely adjacent to the top degenerated spikelet is sterile, which results in a significant decrease in the seed setting rate and the grain number per spike. The wild DPS1 gene is transformed into the rice DPS1 mutant, the degraded phenotype of the mutant spike top can be recovered, the result suggests that the DPS1 gene directly controls degeneration of the rice spike top by regulating programmed cell death, and the rice DPS1 gene can be applied to the directional design of rice spike types and used as an important genetic resource, is helpful to develop molecular markers in molecular breeding practice for conducting early identification and elimination on spike top degradation, and has important guiding significance for improving the rice yield.
