Abstract: The present invention relates to a DoxA protein mutant having an amino acid sequence set forth in SEQ ID NO: 16, and coding gene thereof. The protein mutant or the coding gene thereof can be used for producing epirubicin. The present invention further relates to a Streptomyces capable of efficiently expressing epirubicin, which is constructed by replacing the dnmV gene of a starting Streptomyces in situ with the avrE gene and mutating the doxA gene of the starting Streptomyces into a gene encoding the protein set forth in SEQ ID NO: 16. The fermentation broth of this Streptomyces has an epirubicin potency of up to 102.0 ?g/ml.

Abstract: Embodiments of the disclosure provide a method and apparatus for sharing data. The method includes: initiating the data sharing application on a first terminal; inserting the file to be shared in a webpage of the data sharing application on the first terminal, and generating an URL for the file in the data sharing application; the data-sharing application of the first terminal broadcasts the URL to other terminal, so that other terminals can share the file via the URL. The present disclosure can reduce the cost of data sharing while improve on the real-timeliness.

Abstract: An information publishing method and apparatus are provided that relate to the communications field and are capable of publishing different information for different wireless local area network (WLAN) hotspots. The information publishing method includes: receiving, by an information publishing server, an information content request message sent by a terminal device, where the information content request message carries a media access control (MAC) address of an access point (AP); obtaining, by the information publishing server according to the MAC address of the AP, information content corresponding to the MAC address of the AP; and sending, by the information publishing server, the information content to the terminal device. The present invention is used for information publishing.

Abstract: A processor core and a method for distributive scoreboard scheduling in an out-of-order processor pipeline. In an embodiment, control logic appends operand availability bits to each instruction. The appended operand availability bits form a distributive scoreboard for each instruction. The appended operand availability bits are propagated together with the instruction through multiple stages of the processor pipeline. An instruction dispatch buffer stores the instruction and the operand availability bits. A dispatch controller determines when an instruction is to be issued. The determination is based, at least in part, on the operand availability bits stored in the instruction dispatch buffer.
