Abstract: Provided is a method for intracellularly producing a large amount of a Cry protein in a Bacillus bacterium. A method for producing a Cry protein or a culture product comprising the Cry protein, comprising transforming a Bacillus bacterium with an expression plasmid incorporating a gene encoding the Cry protein operably linked to a regulatory region comprising a ?A-dependent promoter or a ?H-dependent promoter, and culturing the transformed cell, wherein the expression plasmid comprises a polynucleotide encoding a replication protein consisting of the amino acid sequence set forth in SEQ ID NO: 9 or a protein having an identity of 80% or more or more with the amino acid sequence of the replication protein and involved in replication initiation.

Abstract: A photoelectric composite cable and a communication system. The photoelectric composite cable includes an optical unit, an electrical unit, and an outer jacket. The optical unit includes an optical fiber and a ferrule, and the ferrule is sleeved on the optical fiber. The electrical unit includes a wire and a wire jacket, and the wire jacket is sleeved on the wire. The outer jacket wraps outside the optical unit and the electrical unit, and the optical unit and the electrical unit are disposed closely adjacent to each other. An extension direction of the optical unit is consistent with an extension direction of the electrical unit, and at least one convex structure is disposed on an outer wall of the outer jacket.

Abstract: A method of generating multiple channels of optical pulses comprises: providing a continuous wave optical input having an optical power; dividing the optical power of the optical input into equal consecutive slices in the time domain; and allocating the consecutive slices sequentially to two or more optical outputs such that each output forms a channel of optical pulses of equal pulse repetition rate shifted in time relative to the or each other channel.

Abstract: A method for preparing a high-strength, dissolvable magnesium alloy material includes steps of: (1) preparing a magnesium-nickel intermediate alloy, which is Mg25Ni or Mg30Ni; (2) loading; (3) heating, melting and alloying; and (4) refining adequately alloyed magnesium melt at 750±20° C. for about 5 minutes while using RJ-6 as a refining flux and setting the melt still for about 10 minutes. The method allows easy addition of nickel as a component to a magnesium alloy during smelting such that nickel is evenly distributed throughout the magnesium alloy.
