The present invention relates to the field of biotechnology engineering. It provides a recombinant Escherichia coli that can produce fructosylated chondroitin with high yields and the method for constructing the recombinant strain. The present invention discloses a method for constructing an expression plasmid pETM6R1-RBS-glmM-GGGS-glmS that contains a glmM and a glmS gene under regulation of ribosome binding sites. The recombinant plasmid was transformed into E. coli K4 to obtain a recombinant E. coli strain ZQ33 that can produce fructosylated chondroitin up to 3.99 g·L−1 by fed-batch fermentation in a 5-L fermentor, which was increased by 108.90% compared to that of the wild type strain.

Method, apparatus, and computer program product example embodiments enable data distribution in wireless communication networks. In example embodiments, a method comprises receiving a wireless broadcast message including a message ID and an associated distributor address; buffering the received wireless broadcast message and starting an observation window timer for the message if the message ID of the received wireless broadcast message is not stored in a database of message IDs and associated distributor addresses for previously received wireless broadcast messages; calculating a relaying probability for the received wireless broadcast message, based on a number of distributor address entries associated with the message ID in the database, the entries resulting from receiving other wireless broadcast messages having the same message ID during the observation window; transmitting the buffered message following termination of the observation window, based on the calculated relaying probability; and starting a cooling window timer upon termination of the observation window and removing all records containing the message ID from the database following termination of the cooling window.

A control device and a control method during bypassing of power units are provided. The method includes: detecting a first three-phase output electrical signal; calculating a first positive sequence component and a first negative sequence component of the first three-phase output electrical signal; providing a given positive sequence component and a given negative sequence component so as to respectively perform the closed-loop compensation on the first positive sequence component and the first negative sequence component, thereby outputting a second positive sequence component and a second negative sequence component; superimposing the second positive sequence component and the second negative sequence component; and outputting a second three-phase output electrical signal in a preset way.
摘要:
The overlay human interactive proof system (“OHIPS”) and techniques described herein operate in conjunction with any known or later developed computer-based applications or services to provide secure access to resources by reliably differentiating between human and non-human users. Humans have a generally superior ability to differentiate misaligned characters or objects from correctly aligned ones. As such, the OHIP splits an image including one or more visual objects into two or more partial images to form a HIP. The partial images may also be further split into groups of sub-partial images, and/or the partial images (or the sub-partial images) may be moved, so that at any given alignment position, a user can recognize only some visual objects. A user is instructed to reassemble the partial images at one or more predetermined alignment positions using a GUI, and the user is asked to identify information regarding one or more visible objects.

A popularity score or rating may be provided for a third-party content item. The popularity score may be compared with an average score of similar genre third-party content items to determine a relationship of the popularity score relative to the average score of similar genre third-party content items. A popularity or other visual indicator may be provided proximate to the third-party content item to provide a visual indication of the relationship. The popularity indicator may include a bar or a plurality of symbols in some implementations.

Systems and methods of selecting consumers to receive content on a computer network are provided. A user list identifying a first plurality of users having a group of features corresponding to internet activity of the first plurality of users can be obtained at a computing device. A subgroup of features can be selected from the group of features, and a cluster of users of the first plurality of users can be identified. The users of the cluster of users can each have at least one feature of the subgroup of features. A supplemental user having a supplemental feature can be identified. A correlation between the supplemental feature and at least one feature of the subgroup of features can be determined, and an expanded user list that includes at least one of the first plurality of users and the supplemental user can be generated.
