Abstract: The present disclosure discloses a tobacco leaf foliar spraying substance for reducing harmful ingredients in cheroot, a method for reducing carcinogenic components in flue-cured tobacco leaves and flue-cured tobacco shreds. The tobacco leaf foliar spraying substance contains a lotus leaf extract, the harmful chemical ingredients comprise N-nitrosonornicotine, 4-(N-methyl-nitrosamine)-1-(3-pyridinyl)-1-butanone, N-nitrosoanabasine and N-nitrosoanatabine. Foliar spraying is performed on a fertile field by using the lotus leaf extract before tobacco leaves are harvested and modulated, which not only significantly promotesagronomic characters and economic traits of tobacco and alleviates tobacco leaf browning but also effectively reduces harmful chemical ingredients unique to tobacco leaves, such as nitrosamine and nicotine.

Abstract: A method for carrying out grouting between adjacent gateroads in internal-staggered split-level coal mining. A return air gateroad of a stoping face and an inlet air gateroad of a heading face are not on the same level. The return air gateroad of the stoping face is arranged along a roof of a coal seam. The inlet air gateroad of the heading face is arranged along a floor of the coal seam. There is a height difference between the return air gateroad and the inlet air gateroad in a vertical direction. During the construction process, the inlet air gateroad is excavated at a delay distance of 180-200 meters from the return air gateroad. The drilling and grouting are performed while excavating the roadway, where grouting holes are arranged in a single row. A device for implementing the method is also provided.

Abstract: The invention relates to a wide spectrum multi-band detection structure with selective absorption enhancement and its preparation method. The structure comprises a plurality of sub-pixel units capable of detecting incident light in different bands. Each sub-pixel unit is composed of a square well-shaped microstructure array and a metal lower electrode (2), a photosensitive layer (3) and an upper electrode (4) on the surface thereof. The size and array spacing of square well-shaped microstructures in different sub-pixel units are determined according to the detection bands of the sub-pixel units where they are located. The upper openings of the square well-shaped microstructures are hollow to form a resonant cavity, and the adjacent square well-shaped microstructures in the same sub-pixel unit form a resonant cavity, thus solving the problem that the detector structure in the prior art cannot simultaneously realize visible light-near infrared multi-band absorption enhancement detection.

Abstract: Disclosed are compounds of Formula (I), methods of using the compounds for inhibiting ALK2 activity and pharmaceutical compositions comprising such compounds.

Abstract: A method for constructing a multiplex PCR library for high-throughput targeted sequencing: first acquiring a targeted DNA product by means of a high-specificity multiplex PCR reaction, and then digesting with a specific endonuclease, such that a specific molecular barcode is produced at the tail end of the PCR product; thus, the library construction process is more efficient, and the accuracy and sequencing depth of the obtained data are also ensured.

Abstract: The present disclosure relates to the field of biomedicine, in particular to the use of MCM8-cGAS-STING-IFN-I signal pathway as a disease target, including the use in the preparation of an animal model of a disease or the preparation of a product for the diagnosis, prevention, or treatment of a disease. In particular, the present disclosure comprises the use of a reagent for quantitatively detecting the gene expression or protein expression or protein activity of MCM8 in the preparation of a product for the diagnosis of a disease caused by dysfunctional mitophagy or caused by abnormal activation of cGAS-STING-IFN-I signaling pathway.

Abstract: The present disclosure provides a quantum dot particle aggregate and a preparation method therefor, a preparation method for a light conversion device, and quantum dot particles. The preparation method for the quantum dot particle aggregate includes: mixing a plurality of first polymer particles, a first quantum dot solution and a second polymer solution, and drying to obtain an aggregate containing a plurality of quantum dot particles A, where each of the quantum dot particles A includes a core of a first polymer particle and a shell of a second polymer formed by the second polymer, a plurality of first quantum dots are positioned in the shell of the second polymer, and the first polymer particle has a minimum dimension greater than or equal to 0.3 mm. The process reduces the damage to quantum dots and can prolong the life time of application products of quantum dots.

Abstract: A method includes receiving first data based on a region of interest of tissue. The first data may be captured to represent the tissue according to a first moment. The method also includes receiving second data based on the region of interest. The second data may be captured to represent the tissue according to a second moment different from the first moment. The method also includes determining features of the first data according to a first network. The first network may comprise weights. The method also includes determining features of the second data according to the weights. The method also includes determining an input based on the features of the first data and the features of the second data. The method may also include treating a patient or adjusting treatment of the patient diagnosed by one or more of these steps. An apparatus for performing the method is disclosed.

Abstract: Described herein are membrane puncturing devices used for endovascular surgery.

Abstract: A method for managing capacity of lithium ion battery is disclosed. A warning capacity D or C is preset for a discharge process or a charge process. Two anode active materials are mixed and used to form a lithium ion battery. The lithium ion battery is discharged or charged, during which the voltage of the battery is monitored. When the voltage of the lithium ion battery is in a range, a warning is generated for a remaining discharge capacity of the first lithium ion battery reaching the warning capacity D, or a charging capacity of the lithium ion battery reaching the warning capacity C.
