Abstract: Unglycosylated lysostaphin variant protein, nucleic acid molecule, vector and host cell, as well as a method for production of unglycosylated lysostaphin variant protein in a yeast expression system are provided. The proteins are produced in a Pichia pastoris expression system and have been shown to have activity equivalent to wild-type lysostaphin. The lysostaphin variant proteins can be used as therapeutic proteins for treatment of diseases such as Staphylococcus aureus infection.

Abstract: Embodiments of the present invention disclose a method and terminal, an input method and device, a cloud service card, and a system for acquiring a service and relate to the field of cloud computing technologies. A method for acquiring cloud service content according to an embodiment of the present invention includes: acquiring, by a cloud terminal, an identifier of a service card; acquiring, by the cloud terminal, a cloud service instruction set corresponding to the identifier of the cloud service card from a cloud instruction set server according to the identifier of the cloud service card; and acquiring, by the cloud terminal, cloud service content from a cloud service server according to a cloud service instruction in the cloud service instruction set.

Abstract: The present invention relates to a barrel shifter for manipulating bits within computer words. The barrel shifter includes multiple multiplexer stages for rotating single and multiple words. In several embodiments, it provides a half-word alignment in a 2n-bit barrel shifter, rotates a single 32-bit data word or two 16-bit data words, rotates a 2n-bit data word or two 2n?1-bit data half-words, a method of operating a 2n-bit barrel shifter to rotate two 2n?1-bit data words, multiplexer stages for rotating the bits to the left or right based on control signals, such that the stages do not require 2:1 multiplexers between the first and second stages.
