Quantitative Imaging of Single, Unstained Viruses with Coherent X-rays (2008)
Song, Changyong, Jiang, Huaidong, Mancuso, Adrian, Amirbekian, Bagrat, Peng, Li, Sun, Ren, ...
Since Perutz, Kendrew and colleagues unveiled the structure of hemoglobin and myoglobin based on X-ray diffraction analysis in the 1950s, X-ray crystallography has become the primary methodology used...
A coherent review on the x-ray resonant exchange scattering and basic recapitulation of phenomenological aspects of magnetic interactions were attempted in this thesis. Further, application of the...
Self-Similarity Index Estimation via Wavelets for Locally Self-Similar Processes (1999)
Yazhen Wang, Joseph E. Cavanaugh, Changyong Song
Introduction A self-similar process is loosely defined as a stochastic process which generates a sample path that retains the same general appearance regardless of the distance from which it is...
Self-Similarity Index Estimation via Wavelets for Locally Self-Similar Processes (1997)
Yazhen Wang, Joseph E. Cavanaugh, Changyong Song
Many naturally occurring phenomena can be effectively modeled using self-similar processes. In such applications, accurate estimation of the scaling exponent is vital, since it is this index which...
High numerical aperture tabletop soft x-ray diffraction microscopy with 70-nm resolution
Sandberg, Richard L., Song, Changyong, Wachulak, Przemyslaw W., Raymondson, Daisy A., Paul, Ariel, Amirbekian, Bagrat, ...
Light microscopy has greatly advanced our understanding of nature. The achievable resolution, however, is limited by optical wavelengths to ≈200 nm. By using imaging and labeling technologies,...
