Abstract: Disclosed are a plant grain size regulation gene and use thereof, which belong to the technical field of biology. PCFS gene mutants in different crops are obtained by gene editing, and by means of experiments and statistical analysis, it is found that the mutants have a phenotype of enlarged plant grain and part of the mutants have a phenotype of improved stress resistance. The provided gene, mutants, and method for use same are beneficial to increase the crop yield and improve the quality and enhance the resistance of plants to an adverse environment, provide gene resources and technical support for cultivating new plant varieties with large grain weight and high stress resistance, and thereby have important significance and application value for improvement of agronomic traits of crops and breeding of high-yield and high stress-resistant molecules.

Abstract: A closed-track optical delay module, a terahertz system, and a photoelectric system are provided. The closed-track optical delay module comprises a first constraint component with a closed-track line structure, a second constraint component with a straight line groove, a third constraint component with a positioning convex, a light conversion device, a housing, and a driving control device. The positioning convex forms a constraint fit relationship with the closed curve groove and straight line groove. One of the first, second, and third constraint components is connected with the driving control device, the other is fixedly disposed, a next one is connected with the light conversion device and moves parallel to the straight line groove. A light input interface is used for an incident light to be irradiated onto the light conversion device. A light output interface is used for a delayed beam to be emitted from the housing.

Abstract: Provided is a super-resolution image sensor and a producing method thereof such that, on the basis of not changing the arrangement of the image sensitive unit array of the image sensor, by means of the existing micro-lens manufacture techniques, the imaging resolution can be increased by offsetting micro-lens rows in a micro-lens array that covers upon the image sensitive unit array. In some examples, a super-resolution image sensor comprises an image sensitive unit array having image sensitive unit rows aligned with one another, and a micro-lens array covering upon the image sensitive unit array. Relative to a reference micro-lens row in the micro-lens array, the other micro-lens rows are regularly offset. Each micro-lens unit in the reference micro-lens row is center aligned with a corresponding image sensitive unit in a reference image sensitive unit row.

Abstract: A detection method and system are used for a moving target based on multiple sensors on the same platform. N mutually independent image sensors arranged on a monolithic planar array sensor compose an image sensor group, which has a layout where n image sensors are arranged equidistantly on the same line in a travelling direction of a satellite. The method includes respectively collecting image data by the multiple sensors, performing on-board pre-processing to the image data collected by each image sensor, acquiring an image from the received pre-processed image data, and performing operation to the image from different image sensors, to recognize the moving target. The system includes sequentially connected sensor groups, an image data pre-processing device and a wireless transmitting device, a wireless receiving device wirelessly connected with the wireless transmitting device, and a moving target recognition device connected with the wireless receiving device.

Abstract: The present invention discloses a method and device for storing image data, the method includes: receiving image data to-be-stored; extracting basic information of the image data and generating a header file; partitioning the image data by a preset block size according to the basic information of the image data, and generating a data file; and storing the header file and the data file and generating a storage file. In the present invention, image data are stored as double files, so as to add basic information of an image into the image, and in storing a massive-data image, the image is partitioned by a preset size prior to sequential storage, so that when the image is displayed, only one or several sub-blocks of the image are extracted and displayed, allowing quick display of the image with massive data, improving the efficiency of image display.

Abstract: A method for measuring thickness or defect depth by pulsed infrared thermal wave technology is described. The method includes heating a measured object by pulsed heating devices, and at the same time, obtaining a thermal image sequence on the surface of the measured object by an infrared thermography device, and storing the thermal image sequence in a general-purpose memory. The method also includes multiplying a temperature-time curve at every point of the thermal image sequence by a corresponding time, thereby obtaining a new curve. The method also includes calculating a first-order differential and obtaining a peak time thereof. The method also includes use of one or more formulas to thereby determine the thickness or the defect depth of the measured object.
