Multivariate Behav Res. 1976 Jan 01;11(1):119-24. doi: 10.1207/s15327906mbr1101_8.

Given a population simple structure configuration for a set of data, factor transformation methods can be compared in terms of their ability--with samples drawn from this population--to approximate closely the parameter pattern, and to do so with little sampling...

Automatic sub-pixel co-registration of Landsat-8 OLI and Sentinel-2A MSI images using phase correlation and machine learning based mapping.

International journal of digital earth

Skakun S, Roger JC, Vermote EF, Masek JG, Justice CO.
PMID: 32021650
Int J Digit Earth. 2017 Mar 23;1253-1269. doi: 10.1080/17538947.2017.1304586.

This study investigates misregistration issues between Landsat-8/OLI and Sentinel-2A/MSI at 30 m resolution, and between multi-temporal Sentinel-2A images at 10 m resolution using a phase correlation approach and multiple transformation functions. Co-registration of 45 Landsat-8 to Sentinel-2A pairs and...

Chromatographia. 2011 Jan;73(1):67-74. doi: 10.1007/s10337-010-1832-2. Epub 2011 Jan 08.

A rapid, precise, accurate, and selective high-performance liquid chromatographic method with fluorescence detection has been validated and used for analysis of amisulpride in human plasma after a simple solid-phase extraction procedure. Compounds were separated on a CN column with...

Fluorescence cumulants analysis with non-ideal observation profiles.

Methods and applications in fluorescence

Skakun VV, Novikov EG, Apanasovich TV, Apanasovich VV.

Methods Appl Fluoresc. 2015 Nov 26;3(4):045003. doi: 10.1088/2050-6120/3/4/045003.

One of the challenges of fluorescence fluctuation fpectroscopy (FFS) is an adequate approximation of a brightness profile. The key feature of fluorescence intensity distribution analysis (FIDA) is a polynomial approximation of a brightness profile. A broad range of brightness...
