Periodic‐phase‐diagram similarity method for weak signal detection
International Journal of Mechanical System Dynamics, 2021 The periodic‐phase‐diagram similarity method is proposed to identify the frequency of weak harmonic signals. The key technology is to find a set of optimal coefficients for Duffing system, which leads to the periodic motion under the influence of weak ...

Crystallographic phasing from weak anomalous signals [PDF]
Current Opinion in Structural Biology, 2015 The exploitation of anomalous signals for biological structural solution is maturing. Single-wavelength anomalous diffraction (SAD) is dominant in de novo structure analysis. Nevertheless, for challenging structures where the resolution is low (dmin≥3.5Å) or where only lighter atoms (Z≤20) are present, as for native macromolecules, solved SAD ...
