Abstract: A method of generating a classifier by using a small number of labeled images includes: pre-training a wide residual network by using a set of labeled data with a data amount meeting requirements, and determining portions of the pre-trained wide residual network except for a fully connected layer as a feature extractor for an image; randomly selecting, for a N-class classifier to be generated, N classes from a training set for each of a plurality of times; and for N classes selected each time: randomly selecting one or more images from each class of the N classes as training samples; extracting a feature vector from training samples of each class by using the feature extractor; inputting a total of N feature vectors extracted into a classifier generator; and sequentially performing a class information fusion and a parameter prediction for the N-class classifier by using the classifier generator.

Abstract: A plant sterility-related gene is disclosed, in particular to a dominant male sterility-related gene from rice and application of an encoding protein thereof in creating a rice dominant male sterile line. The present invention provides a rice dominant male sterile gene SMS and application thereof. The rice dominant male sterility-related gene SMS may be used for creating a new dominant male sterile line, thereby strengthening use of the advantages of a rice hybrid. The TO generation of transgenic plant line with overexpression of the rice dominant male sterility related gene SMS shows pollen abortion or no pollen, which indicates that the transgenic plant overexpressing this gene can obtain a new sterile material.

Abstract: The synthesis and characterization of a platinum (II) terpyridine system tethered with a latent organic dye of rhodamine derivative as colorimetric and fluorescent sensory moiety has been reported to show selective Hg2+ ion sensing behavior. The interplay of aggregation/de-aggregation behavior of the alkynylplatinum(II) terpyridine complex and the ring-opening process of rhodamine derivative has been investigated. The spectral change of aggregation NIR emission at 800 nm and rhodamine fluorescence at 585 nm provides a possible ratiometric luminescence measurement. Morphological studies from TEM and SEM images showing nanospherical structures confirmed the aggregation in the absence of Hg2+ ion.

Abstract: A device and a spectrometer for quantitatively detecting carbon 14 isotope by a dual-wavelength method. Two mid-infrared lasers with different wavelengths are locked in an optical cavity of a sample chamber, to ensure the two lasers are collinear. The cavity length of the optical cavity is adjusted by a cavity length adjusting unit, to tune the mode frequency of the optical cavity, and then tune the frequencies of the two mid-infrared lasers, so that the frequencies of the two mid-infrared lasers match with different energy levels of the target isotope molecule simultaneously. After the frequencies of the mid-infrared lasers match with the energy levels of the target isotope molecule simultaneously, the target isotope molecule is excited by two mid-infrared lasers simultaneously, and the optical cavity output signal of the second mid-infrared laser passing through the optical cavity is detected.
