The present invention provides a plate (1; 2) comprising an array of pores (11; 21) for carrying out chemical or biological reactions, wherein each of the pores (11; 21) comprises a reaction chamber having at least one opening (111; 211) on a surface (12; 22) of the plate (1; 2). The array of pores (11; 21) is composed of a plurality of adjacent pore blocks (13; 23), wherein each pore block (13; 23) is composed of a plurality of adjacent rows of pores, and wherein at least one blank portion (14; 24) is provided between the rows of pores in each pore block (13; 23). Here, the blank portion (14; 24) is specifically a portion of the surface (12; 22) of the plate (1; 2) and has no pore opening (111; 211). Furthermore, the present invention provides a method for multiple imaging of such a plate (1; 2) using an imaging system.

The present application relates to a method, device and equipment for suppressing clutter in a single pulse forward-looking imaging of a polarization radar. The method comprises: generating multiple sets of weights as multiple polarization states synthesized in a digital domain according to the expression form of the Jones vector; calculating the single pulse angle measurement results of each range-Doppler unit under multiple polarization states to form a polarization-angle sequence; calculating the entropy of the polarization-angle sequence of each range-Doppler unit as the polarization angle entropy; constructing a mask filter for range-Doppler data according to the polarization angle entropy; inputting the range-Doppler-sum-difference channel echo data into the mask filter, performing single pulse angle measurement processing on the range-Doppler-sum-difference channel echo data after the mask filter acts, accumulating each angle measurement result and the sum channel energy to the corresponding range-azimuth unit, and obtaining a distance-angle diagram for clutter suppression. The present method can suppress sea clutter by utilizing the information provided by the polarization dimension.

This application presents a gRNA probe library, its preparation and design methods, a method for targeting genes, and a nucleic acid imaging method. This application combines gRNA probes containing modified groups with nucleases, enabling dynamic observation of DNA and RNA by binding to target genomic sequences or RNA transcripts in living cells. By utilizing fluorescently labeled crRNAs, tracrRNAs, and sgRNAs, this application achieves real-time imaging of repetitive and non-repetitive sites, establishing a powerful gene imaging toolkit. Furthermore, the gRNA probe library prepared in this application will be applied to CRISPR systems for gene editing, transcriptional regulation, gene targeting, and delivery.

The invention relates to a polarized radar monopulse forward-looking imaging clutter suppression method, device and equipment. The method comprises the following steps: generating multiple groups of weights as multiple polarization states for digital domain synthesis according to an expression form of a Jones vector; calculating monopulse angle measurement results of each distance-Doppler unit in various polarization states to form a polarization-angle sequence; calculating the entropy of the polarization-angle sequence of each distance-Doppler unit as the polarization angle entropy; constructing a mask filter of distance-Doppler data according to the polarization angle entropy; and inputting the distance-Doppler-sum-difference channel echo data into a mask filter, performing monopulse angle measurement processing on the distance-Doppler-sum-difference channel echo data acted by the mask filter, and accumulating each angle measurement result and sum channel energy into a corresponding distance-azimuth unit to obtain a clutter suppression distance-angle diagram. By adopting the method, sea clutter suppression can be realized by using the information provided by the polarization dimension.
