This invention belongs to the field of plant genetic engineering, specifically relating to an isolated nucleic acid molecule encoding the Sapindus mukorossi SmHD-ZIP34 protein and its application. The isolated nucleic acid molecule has a nucleotide sequence as shown in SEQ ID NO.1, or encodes an amino acid sequence as shown in SEQ ID NO.2. This invention reveals for the first time the dual function of this isolated nucleic acid molecule in simultaneously regulating flowering time and sex differentiation in plants. Experiments have shown that overexpression of this nucleic acid molecule in Arabidopsis thaliana significantly promotes flowering and pistil elongation, and inhibits stamen development by downregulating the core pathway of stamen development, leading to a reduction in the number of stamens and pollen abortion. The nucleic acid molecule resource provided by this invention offers an effective solution to the problems of long breeding cycles and low fruit set rates due to male flower dominance in economic forest trees such as Sapindus mukorossi, and can be used to cultivate high-yielding new germplasm with early flowering, fewer males, and more females.

The invention relates to a film hole detection system based on image recognition and a detection method thereof, and belongs to the technical field of intelligent manufacturing and laser processing process control, and the method comprises the following steps: S1, adopting a multi-mode sensing module to collect various physical signals of a processing area in real time so as to form a multi-dimensional data stream; s2, inputting the multi-dimensional data stream into a digital twinning and simulation module to solve total interface stress, and generating a three-dimensional transient stress field distribution diagram; s3, inputting the multi-dimensional data stream into a defect prediction and early warning module to generate a defect occurrence probability; s4, generating a graded early warning signal based on the defect occurrence probability and a preset graded early warning threshold value; s5, based on the total interface stress and the graded early warning signal, a pulse energy control law is adopted, and an adjusted pulse energy parameter is solved; and S6, the adjusted pulse energy parameters are input into a laser machining execution module to achieve closed-loop control over the laser machining process, and an unprecedented data basis is provided for deep analysis and accurate prediction.

The invention provides a research scheme generation method and device, electronic equipment and a storage medium, and relates to the technical field of automatic research design. The method comprises the following steps: finding knowledge fragments related to a research concept from a pre-constructed knowledge database according to the research concept, and generating a preliminary research scheme according to the knowledge fragments; screening out target data from a target database according to the preliminary research scheme, and if the target data does not meet a preset requirement, adjusting the preliminary research scheme and re-screening the target data until the target data meets the preset requirement to obtain an effective data set; and performing data statistical analysis on the effective data set, if a statistical analysis result does not accord with an expected result set by the preliminary research scheme, adjusting the preliminary research scheme until the statistical analysis result accords with the expected result, and combining a final statistical analysis result to generate a final research scheme. Through dynamic adjustment and a closed-loop feedback mechanism, the research scheme can be optimized in real time according to actual data feedback.
