Abstract: A gene related to biosynthesis of ergothioneine is provided. Based on five synthesis genes of ergothioneine in Mycobacteroides abscessus, only an encoding sequence of each of the five genes is retained, and a gene structure of an encoding region in each gene is optimized to obtain genes related to the biosynthesis of the ergothioneine that are stably expressed in rice. These genes have sequences set forth in SEQ ID NO: 1 to SEQ ID NO: 5, and encoded proteins thereof have amino acid sequences set forth in SEQ ID NO: 6 to SEQ ID NO: 10. The gene is transferred into rice to construct a transgenic rice molecular farm to produce the ergothioneine. As a molecular farm, rice seeds do not contain alkaloids or allergens that are harmful to the human body. Moreover, biosynthesized ergothioneine shows the advantages of easy extraction and processing and of low production cost.

Abstract: An exploit detector hooks functions of a WebAssembly engine API that include functions invoked when creating a WebAssembly instance, when permissibly modifying read-write-execute (RWX) memory allocated for a WebAssembly instance, and when calling an exported WebAssembly function. Upon invocation of the hooked instance creation function(s), the detector obtains an address of RWX memory allocated for the instance, reads data stored there, and records an association between the address and the data. If the hooked function(s) for permissibly modifying RWX memory is invoked, the detector updates the data stored in the recorded association with the modified data read from the RWX memory. Based on invocation of the hooked function(s) associated with WebAssembly export function calls, the detector reads the current data in the RWX memory to be executed and compares this data to the data recorded in association with the address. If the actual and expected data differ, the detector detects a browser exploit.

Abstract: Balancing content distribution between a machine learning model and a statistical model provides a baseline assurance in combination with the benefits of a well-trained machine learning model for content selection. In some implementations, a server receiving requests for a content item assigns a first proportion of the received requests to a first group and assigns remaining requests to a second group. The server uses a machine learning model to select variations of the requested content item for responding to requests assigned to the first group and uses a statistical model to select content variations for requests assigned to the second group. The server obtains performance information, e.g., acceptance rates for the different variations, and compares performance of the different models used for content selection. Audience share assigned to the machine learning model is increased when it outperforms the statistical model and decreased when it underperforms the statistical model.
