Abstract: A method for testing burning performance of a dark-colored cigarette using a dark-colored cigarette paper is provided. The dark-colored cigarette paper has a grayscale less than 255. The method includes: simulating, by a robotic arm, a cigarette smoking process and environment; acquiring, by a full-vision camera system, an image of a burn line and ash column region of the dark-colored cigarette; and analyzing a burning performance indicator of the dark-colored cigarette according to coordinate information of the burn line and ash column region. The method is based on a surface reflection characteristic of the dark-colored cigarette paper and a principle of optical reflection to light and highlight an edge of the dark-colored cigarette sample by a light source at a certain angle from a side. In this way, the method forms a chromatic aberration to localize the dark-colored cigarette sample, thereby testing the burning performance of the dark-colored cigarette sample.

Abstract: A method for comprehensively analyzing and/or evaluating cigarette burning quality index is disclosed. The steps include collecting cigarette burning quality index data, filtering the cigarette burning quality index data, standardizing cigarette data, and measuring cigarette burning quality. The importance of the cigarette burning quality indicators can also be evaluated. The method for comprehensively analyzing and/or evaluating cigarette burning quality indicators can reflect general laws more accurately by maintaining the sample distribution through a singularity detection method, and analyzing correlations of each index with cigarette performance from multiple perspectives, to fuse them into a comprehensive measurement value. The importance ranking and weight of indicators can be obtained more completely and stably.

Abstract: A resource processing method and apparatus, an electronic device, and a storage medium are provided. The resource processing method in embodiments of this application includes: in a case of determining that a target service is in an inactive state, performing, on a target resource, target processing, including first target processing and second target processing. The first target processing includes: being up to implementation; maintaining a state of the target resource; releasing the target resource in a case that the target resource has been established; and establishing the target resource in a case that the target resource has not been established.

Abstract: The ends of cell-free DNA fragments may be used for analysis of a biological sample. In some embodiments, DNA from a urine sample may be analyzed. Cell-free DNA fragments often include jagged ends, where one end of one strand of double-stranded DNA extends beyond the other end of the other strand. The length and amount of these jagged ends may be used to determine a level of a condition of an individual. The density of ends of fragments in certain regions may also be used in classifying the level of a condition. Additionally, DNA fragments may show a periodic pattern with the amount of DNA fragments corresponding to a length of the overhang. The periodicity may be analyzed to determine properties of a biological sample. Jagged ends may also be analyzed with a technique that avoids trimming overhanging 3? ends of a double-stranded DNA.

Abstract: A method and system for implementing a smart card remote operation based on a smart card web server is provided. As a mobile phone is prompted to activate update by a short message transmitted thereto, the problem of addressing the mobile phone is effectively solved. A remote network is accessed by using a TCP/IP protocol stack to conveniently and reliably update bulk data. The mobile phone is used as a gateway to connect a smart card and a remote management server, thereby realizing security identity authentication, data integrality verification, implementation of data encryption and customizable access policies, and increasing demand of an operator for enhancing value-added services of the smart card.

Abstract: The present invention provides a method of using cereal non-storage protein as fusion carrier to highly express small peptides in host endosperm cells. The method includes the steps of providing an endosperm-specific promoter and a DNA leading sequence encoding an endosperm-specific signal peptide; providing the gene of a non-storage protein as fusion carrier and an target gene; constructing a expression vector containing the promoter and DNA leading sequence, the gene of the fusion carrier, and a target gene; and expressing the expression vector in a host endosperm cell. Also provided in the invention are a vector constructed there from and the use thereof.
