摘要： The present invention provides a method for high-efficiency production of pinoresinol by use of an H2O2 auto-scavenging enzymatic cascade. It uses eugenol as the substrate, which is relatively inexpensive and is industrially available. It uses an enzymatic cascade to remove H2O2 produced in the process of pinoresinol synthesis, thereby reducing its inhibitory effect on the enzyme activity. In addition, the present invention uses whole cells as a catalyst, which can continuously regenerate cofactors needed by the enzyme, thus eliminating the need for exogenous addition of expensive cofactors during the reaction. The yield of the present invention can reach 7.12 g/L and the conversion rate is 61.55%.

摘要： Provided is a method applied to a system including a plurality of sensors, a proxy, and a server. The method includes: measuring objects by the plurality of sensors to obtain first measurement values; computing a correlation among the first measurement values by the server based on the first measurement values; computing an actual measurement value of a second measurement value by the proxy based on the first measurement values and a given function; verifying the plurality of sensors by setting one or more sensors as verification target sensors in turn by the server at predetermined timing; computing a predicted value of the second measurement value by the server based on the correlation and the first measurement values obtained from the other sensors; and outputting the predicted value of the second measurement value instead of the actual measurement value thereof at least during the verification of the verification target sensors.

摘要： In a switching regulator control circuit according to aspects of the invention, a drain current is converted to a voltage Vis with a resistance. The voltage is delivered to a multiplication circuit. The multiplication circuit generates and outputs a voltage that is a product signal of the voltage and a voltage that is proportional to a duty factor. A comparator circuit compares the voltage with an error signal delivered to the other comparison input terminal of the comparator. When the voltage has reached the error voltage, the comparator delivers a turn-off instruction through an OR circuit to a terminal of a flip-flop.

摘要： A regular expression matching method and system, and a searching device are provided. First, the searching device performs string filtering on a data stream to be matched, in which if keywords in the data stream and preset character words have at least one same character, the searching device indicates that the data stream passes through the string filtering. Then the searching device performs regular expression filtering on the data stream passing through the string filtering. In a string filtering process through the method, system, and device, when Hash mapping positions of the keywords of the data stream are a subset of the Hash mapping positions of the character words, it indicates that the data stream passes through the string filtering, and it is not required to store the keywords and further compare the keywords with the character words, thereby saving the storage space and improving performance.
