Speckle-interferometry and speckle-correlometry of GB-speckles
Frontiers in Bioscience, 2019 A new method of coding of genetic information using laser speckles has been developed. Specific technique of transforming the nucleotide of gene into a speckle pattern (gene-based speckles or GB-speckles) is suggested. Reference speckle patterns of omp1 gene of typical wild strains of Chlamydia trachomatis of genovars D, E, F, G, and J are generated ...

Exploring Thousands of Nearby Hierarchical Systems with Gaia and Speckle Interferometry [PDF]
Astronomical Journal, 2023 There should be about 10,000 stellar hierarchical systems within 100 pc with primary stars more massive than 0.5 M ⊙, and a similar amount of less-massive hierarchies.

Speckle Interferometry at SOAR in 2021 [PDF]
Astronomical Journal, 2022 The speckle interferometry program at the the 4.1 m Southern Astrophysical Research Telescope (SOAR), which started in 2008, now has accumulated over 30,300 individual observations of 12,700 distinct targets. Its main goal is to monitor orbital motion of
