    Abstract: A frequency multiplier based on a low dimensional semiconductor structure, including an insulating substrate layer, a semiconductor conducting layer arranged on the surface of the insulating substrate layer, an insulating protective layer arranged on the surface of the semiconductor conducting layer, an insulating carving groove penetrating the semiconductor conducting layer, an inlet electrode arranged on the side surface of the semiconductor conducting layer, and an outlet electrode arranged on the side surface corresponding to the access electrode is provided. The semiconductor conducting layer comprises two two-dimensional, quasi-one-dimensional, or one-dimensional current carrying channels near to and parallel to each other. The frequency multiplier has advantages that the structure is simple, the process is easy to implement, no extra filter circuit needs to be added, dependence on material characteristics is little, and the selection range of materials is wide.

    Abstract: The present invention discloses a nucleic acid detection kit and a detection method based on photo-controlled CRISPR-Cas, wherein the kit comprises silent guide RNA and Cas protein; the silent guide RNA is formed by annealing hybridization of silent nucleotide and guide RNA; the guide RNA, designed according to a target nucleic acid sequence, includes two regions, i.e. a repetitive region and a spacer region; the silent nucleotide is completely complementarily paired with a the of the guide RNA, or is completely paired with a the of the guide RNA; the bases of the silent nucleotide are linked by PC linker; and the Cas protein is Cas12 protein or Cas13 protein. Although this method separates the nucleic acid amplification from the CRISPR-Cas detection in time, it can allow them to be completed in the same closed reaction tube, thereby avoiding the transfer process of uncapped reagent, ensuring that the detection is not affected by aerosol pollution while ensuring high detection sensitivity.

    Abstract: A noninvasive method and system for sleep apnea detection. The noninvasive method for sleep apnea detection comprises: collecting vital sign signals of a sleeping user; performing structured processing on the vital sign signals of the sleeping user to remove invalid signals to obtain a set of valid vital sign signals; extracting multi-dimensional morphological features from a sleep respiratory signal and performing feature training on multiple initial models of a classifier by means of the multi-dimensional morphological features to obtain a sleep breathing detection model; and inputting the set of valid vital sign signals into the sleep breathing detection model and performing signal processing to obtain probability data of the sleeping user experiencing sleep apnea; inputting the set of valid vital sign signals into a sleep breathing detection model and performing signal processing to obtain predicted probability of the sleeping user suffering from sleep apnea.
