Abstract: An artificial propagation method of Sinocyclocheilus rhinocerous, comprising placing female and male parent fish in a sterilized culture container in which a black cave simulant is placed in advance, strictly controlling the environmental parameters of the parent fish culture. The method realizes natural spawning and sperm production of S. rhinocerous under artificial conditions without using oxytocin. There is no oxytocin used in the artificial propagation, thus not only obtaining a higher fertilization rate and incubating rate, but also reducing the aquaculture cost. The operation is simpler and faster. At the same time, different feeds are fed in different growth stages according to the different growth characteristics of each stage of S. rhinocerous fry, thereby increasing the survival rate and reducing the deformity rate of fries. Therefore, the method provided by the present disclosure realizes efficient artificial propagation method of S. rhinocerous.

Abstract: An encryption manager generates an unencrypted validation code to authenticate a transaction associated with a user profile. The encryption manager generates an encrypted validation code based on the unencrypted validation code and an encryption policy associated with the user profile. The encryption manager sends the encrypted validation code to a user device associated with the user profile. The transaction is authenticated if a decrypted validation code generated based on user input matches the unencrypted validation code.

Abstract: A model for automated item generator of the graphic intelligence test solves the tremendous time consuming problem for manually devising the graph intelligence item. At the same time, the invention can automated generate more complicated, more transformations and better layout graph for intelligence test, which are hard to predict. The model utilizes the 12 branch tree as the expressing pattern of matrix graph item, and 8 branch trees as the expressing pattern of series graph item. The automated generating item methods have been presented, and the difficulty of the item has also been validated with the similarity of the optional answers and difficulties of the rules and complexity of the sub-graph. The best feature of the model is that a big amount of the graph item for intelligence test can be generated at one time by the computer, instead of manually devising the matrix graph or series graph for intelligence test.
