Abstract: The present inventors confirmed that when a brazzein expression recombinant vector for high expression of brazzein in Saccharomyces cerevisiae was prepared and a S. cerevisiae strain Y2805 was transformed with the recombinant vector, the expression level of brazzein was particularly high, thereby completing an optimal expression system for mass-producing brazzein. Further, when the brazzein expression system is cultured under the optimal culture conditions according to the present invention, the amount of brazzein produced is further increased, the purification process is simple, and costs are reduced. Therefore, it is expected that the brazzein expression system according to the present invention can be widely used for mass-producing and commercializing brazzein, which is a sweet protein.

Abstract: Provided is a block size adjustment method in a blockchain network including: (a) setting the block size to an initial value; (b) waiting for a transaction request, and processing a transaction to be requested; (c) if the processing of the requested transaction is successful, generating a block according to the block size, and increasing the block size to increase the number of transactions that can be processed at one time; and (d) if the processing of the requested transaction fails, reducing the block size without block generation to reduce the number of transactions that can be processed at one time. By repeatedly performing steps (b), (c) and (d) using the block size adjusted by whether or not a transaction is processed, the block size is flexibly adjusted and a block according to the adjusted block size is generated. Therefore, the throughput of the blockchain network can be significantly improved.

Abstract: An exchange computer system may compress price data associated with a financial product. The financial product may be, e.g., a type of futures contract, a type of option, a type of over-the-counter (OTC) forward, a type of OTC option, a type of security, or other type of financial product. The computer system may access data that indicates prices for a financial product at each of multiple times, generate data representing changes in prices, and stores codes representing that generated price change data. Price change categories may be identified for price changes corresponding to different times. Codes may then be selected based on the identified price change categories and stored. The stored codes may be used for price validation and/or other purposes.
