    • The present invention discloses an asymmetric PCR amplification method, its special primer and application, aims to provide a simple, effective PCR amplification for preparation of single-stranded product. The asymmetric PCR primer of the invention comprises some PCR primer pairs, in which an unrelated nucleic acids sequence to target sequence to be detected is added onto 5′-terminal of one primer. The asymmetric PCR amplification provided includes the steps: 1) preparative denaturing; 2) repetitiously denaturing, primers annealing, extending cycles as the first stage of PCR amplification; 3) repetitiously denaturing, primer extending cycles as the second stage of PCR amplification, wherein an unrelated nucleic acids sequence to target sequence to be detected is added onto 5′-terminal of one PCR primer of each pair in extension. With the asymmetric PCR amplification of the invention, high throughput of single-stranded products can be obtained, single PCR amplification or multiple PCR amplification can be carried out. And the method can be widely used in detection of nucleic acids.

    • A method may include constructing an auxiliary graph for a network comprising a plurality of network elements, the network elements having an Internet Protocol layer, a lower layer, and a wavelength layer, the auxiliary graph including a plurality of directed edges, the plurality of directed edges indicative of connectivity of components of the plurality of network elements. The method may further include: (i) deleting directed edges from the auxiliary graph whose available bandwidth is lower than the required bandwidth of a selected demand; (ii) finding a path for the demand on the auxiliary graph via remaining directed edges; (iii) deleting at least one directed edge of the auxiliary graph on the wavelength layer along the path; (iv) adding lower layer lightpath edges to the auxiliary graph for a lower layer lightpath for the path; and (v) converting lower layer lightpaths to Internet Protocol lightpaths if a conversion condition is satisfied.
