    摘要: A system and method for backing up a database, where the system has read threads running simultaneously, write threads, and data buffers. Each read thread repeats the following operations until all the data is backed up: read a block of data from the database, compress the data using a dynamic compression ratio which is initialized and adjusted after every compression, write the data to an available data buffer until the data buffer is full, write to the next available data buffer once the data buffer is full, and determine a new compression ratio. A controller determines the new compression ratio using either a method that monitors the timing of system components and/or a method that monitors CPU consumption.

    摘要: The invention is a method for detecting a reaction product which signals the presence of a reaction product inducer such as an enzyme. The method enables the recognition of epitopes that form the basis of a detection strategy without the need for specific antibodies to the epitope. In the method, a directly or indirectly labeled modular domain and a biotinylated form of the cognate peptide ligand are used as the basis for a measurable interaction. The peptide ligand can be masked by modifications through, for example, phosphorylation of the Ser or Thr residue, or extension of the amino acid sequence beyond the C-terminal Val. Because the masked residues are critical to binding of the labeled modular domain, masking of at least one of the residues prevents binding. Upon treatment of the masked residue by the appropriate enzyme, (e.g., treatment of the phosphorylated residue with a phosphatase enzyme, or treatment of the extended residue with a protease enzyme, the peptide is converted to the original unmasked ligand that is capable of binding to the labeled modular domain and forming a measurable complex.
