Abstract: A method for preparing a universal microbial medium by eutectic system-based cellulose liquefaction. The method includes: 1) mixing ionic liquid and cellulose, where the ionic liquid is preheated; 2) mixing a mixed solution I obtained in step 1) and distilled water; 3) filtering a mixed solution II obtained in step 2); and 4) diluting a filtrate obtained in step 3) with the distilled water to obtain the carbon source. A medium prepared from the carbon source can be used for culturing various microorganisms, with a desirable growth state of the microorganisms.

Abstract: A network device obtains to-be-detected mirrored traffic between a client and a server, obtains a first session information sequence based on the to-be-detected mirrored traffic, where the first session information sequence includes a plurality of pieces of session information, the plurality of pieces of session information have a one-to-one correspondence with a plurality of login sessions, and an arrangement order of the plurality of pieces of session information in the first session information sequence is consistent with a chronological order of the plurality of login sessions, using the first session information sequence as a first Markov chain, and obtains a state chain probability value of the first Markov chain, and determines, based on the state chain probability value of the first Markov chain and a first benchmark probability value, whether the plurality of login sessions are a brute force attack.

Abstract: The present disclosure discloses a method, apparatus and electronic device for determining skin smoothness, which relates to the field of computer vision technologies. The specific implementation solution is as follows: when the skin smoothness is calculated, an image to be detected including a face area is obtained first, and then the image to be detected and a smoothness analysis mask image corresponding to the image to be detected are inputted into a deep learning model to obtain a plurality of feature vectors for indicating the skin smoothness of the face. Because the smoothness analysis mask image does not include preset factors including at least one of five sense organs, reflection and hair, the influence of the preset factors on the skin smoothness is avoided, so that the accuracy for the skin smoothness of the face is ensured to a certain extent.

Abstract: A cable connector assembly (100, 100?) includes a first cable end (1, 1?), a second cable end (2, 2?), and a cable (3, 3?) connecting between the first cable end and the second cable end. The first cable end has a first insulative body (11, 11?) and a first connecting tongue (12, 12?) extending beyond the first insulative body. The second cable end has a second insulative body (211, 211?), a third insulative body (212, 212?) extending from the second insulative body, a second connecting tongue (23, 23?) extending beyond the second insulative body, and a third connecting tongue (24, 24?) extending beyond the third insulative body. The cable connector assembly has a cover (25, 25?) covering the second cable end along a first direction. The cover is moveable with respect to the second cable end in a second, perpendicular direction to cover one of the two connecting tongues.

Abstract: A method of making a europium ion doped working electrode, which comprises the following steps: anodizing a Ti foil to obtain an electrode body; dipping the electrode body into an acid solution, which contains 0.035 to 0.045 M of europium ions, followed by thermal treating in a closed system under 100° C. to 180° C. and calcining. Based on the steps above, the fabrication of a working electrode is simplified and the cost is decreased. Also, a europium ion doped working electrode that can enhance the photoelectric conversion efficiency of a back side illuminated TiO2-based DSSC to 153.7 times is obtained.

Abstract: A method of fabricating a composite membranes containing a metal ion adsorbent, the method comprising the following steps: mixing a metal ion adsorbent powder and a solvent to form a mixture, wherein the solvent is capable of dissolving cellulose; mixing the mixture and cellulose to form a gel blend; removing the solvent from the gel blend, and drying the gel blend to obtain a composite membrane containing a metal ion adsorbent. By means of mixing metal ion adsorbent and cellulose by phase inversion to obtain the composite membrane containing a metal ion adsorbent, the composite membrane containing a metal ion adsorbent can remove heavy metal ions from industrial wastewater.
