Comprehensive reviews in food science and food safety

Granato D, Putnik P, Kovačević DB, Santos JS, Calado V, Rocha RS, Cruz AGD, Jarvis B, Rodionova OY, Pomerantsev A.
PMID: 33350122
Compr Rev Food Sci Food Saf. 2018 May;17(3):663-677. doi: 10.1111/1541-4337.12341. Epub 2018 Mar 30.

In the last decade, the use of multivariate statistical techniques developed for analytical chemistry has been adopted widely in food science and technology. Usually, chemometrics is applied when there is a large and complex dataset, in terms of sample...

Procrustes Cross-Validation of short datasets in PCA context.

Talanta

Pomerantsev AL, Rodionova OY.
PMID: 33676660
Talanta. 2021 May 01;226:122104. doi: 10.1016/j.talanta.2021.122104. Epub 2021 Jan 15.

We suggest using a new tool, Procrustes cross-validation, as an alternative to a regular cross-validation for short datasets where each sample is important and, therefore, cannot be removed in line with the conventional leave-one-out cross-validation procedure. The advantages of...

Diffuse Reflectance Spectroscopy of Hidden Objects, Part I: Interpretation of the Reflection-Absorption-Scattering Fractions in Near-Infrared (NIR) Spectra of Polyethylene Films.

Applied spectroscopy

Pomerantsev AL, Rodionova OY, Skvortsov AN.
PMID: 28357880
Appl Spectrosc. 2017 Aug;71(8):1760-1772. doi: 10.1177/0003702817694182. Epub 2017 Mar 30.

Investigation of a sample covered by an interfering layer is required in many fields, e.g., for process control, biochemical analysis, and many other applications. This study is based on the analysis of spectra collected by near-infrared (NIR) diffuse reflectance...

High speed rotational atherectomy in coronary artery disease.

Surgical technology international

Raju PK, Stertzer SH, Shaw RE, Pomerantsev E, Zipkin R, Myler RK, Murphy M.
PMID: 25951572
Surg Technol Int. 1993 Oct;2:255-8.

Despite major advances in its diagnosis and management, coronary artery disease remains the major cause of death accounting for 45.3 percent of all deaths in the United States. One of the major milestones in the treatment of coronary artery...

Chemometrics in analytical chemistry-part I: history, experimental design and data analysis tools.

Analytical and bioanalytical chemistry

Brereton RG, Jansen J, Lopes J, Marini F, Pomerantsev A, Rodionova O, Roger JM, Walczak B, Tauler R.

Chemometrics has achieved major recognition and progress in the analytical chemistry field. In the first part of this tutorial, major achievements and contributions of chemometrics to some of the more important stages of the analytical process, like experimental design,...

Diffuse Reflectance Spectroscopy of Hidden Objects. Part II: Recovery of a Target Spectrum.

Applied spectroscopy

Pomerantsev AL, Rodionova OY, Skvortsov AN.
PMID: 28374600
Appl Spectrosc. 2017 Aug;71(8):1773-1784. doi: 10.1177/0003702817695288. Epub 2017 Apr 04.

In this study, we consider the reconstruction of a diffuse reflectance near-infrared spectrum of an object (target spectrum) in case the object is covered by an interfering absorbing and scattering layer. Recovery is performed using a new empirical method,...
