Homogenization of quasi-1d metamaterials and the problem of extended bandwidth.

Optics express

Goncharenko AV, Venger EF, Pinchuk AO.
PMID: 24663534
Opt Express. 2014 Feb 10;22(3):2429-42. doi: 10.1364/OE.22.002429.

We derive approximate analytical expressions for the effective permittivity tensor of two-phase metamaterials whose geometry is close to one-dimensional (quasi-one-dimensional metamaterials). Specifically, we consider the metamaterial made of parallel slabs with width given by a linear or parabolic function....

Calibration transfer between different analytical methods.

Talanta

Panchuk V, Kirsanov D, Oleneva E, Semenov V, Legin A.
PMID: 28501196
Talanta. 2017 Aug 01;170:457-463. doi: 10.1016/j.talanta.2017.04.039. Epub 2017 Apr 18.

The procedure for transfer of calibration models between different analytical methods is suggested. It is based on the direct standardization (DS) algorithm earlier suggested for data conversion between physically different instruments of the same type. As a result, multivariate...

Impairment of Tissue-Resident Mesenchymal Stem Cells in Chronic Ulcerative Colitis and Crohn's Disease.

Journal of Crohn's & colitis

Grim C, Noble R, Uribe G, Khanipov K, Johnson P, Koltun WA, Watts T, Fofanov Y, Yochum GS, Powell DW, Beswick EJ, Pinchuk IV.

Absorption cross section of gold nanoparticles based on NIR laser heating and thermodynamic calculations.

Scientific reports

Alrahili M, Savchuk V, McNear K, Pinchuk A.
PMID: 33139828
Sci Rep. 2020 Nov 02;10(1):18790. doi: 10.1038/s41598-020-75895-9.

We present a method for measuring the optical absorption cross section ([Formula: see text]) of gold nanoparticles (GNPs) based on optically heating the solution of GNPs with an 808 nm near-infrared (NIR) laser and measuring the temperature increase of...

Signal Smoothing with PLS Regression.

Analytical chemistry

Panchuk V, Semenov V, Legin A, Kirsanov D.
PMID: 29620358
Anal Chem. 2018 May 01;90(9):5959-5964. doi: 10.1021/acs.analchem.8b01194. Epub 2018 Apr 10.

Smoothing of instrumental signals is an important prerequisite in data processing. Various smoothing methods were suggested through the last decades each having their own benefits and drawbacks. Most of the filtering methods are based on averaging in a certain...

[Efficiency of hardware-assisted tools in forensic expertise].

Sudebno-meditsinskaia ekspertiza

Pinchuk PV, Kolkutin VV.
PMID: 15747848
Sud Med Ekspert. 2005 Jan-Feb;48(1):30-3.

The authors analyze the efficiency of special-purpose hardware-assisted tools (SHT) in forensic expertise. Unlike clinical medicine, in which the methods of quantitative and qualitative analysis are comprehensively used in choosing drugs, issues related with providing the state forensic-expertise facilities...

Differential effects of age on circulating and splenic leukocyte populations in C57BL/6 and BALB/c male mice.

Immunity & ageing : I & A

Pinchuk LM, Filipov NM.
PMID: 18267021
Immun Ageing. 2008 Feb 11;5:1. doi: 10.1186/1742-4933-5-1.

BACKGROUND: Despite several reports on age-related phenotypic changes of the immune system's cells, studies that use a multipoint age comparison between the specific and innate immune cell populations of prototypical Th1- and Th2-type polarized mouse strains are still lacking.RESULTS:...

Pleural Metastasis of Atypical Bronchial Carcinoid.

The Korean journal of thoracic and cardiovascular surgery

Zinchenko EI, Maslak OS, Pischik VG, Obornev AD, Kovalenko AI.
PMID: 32919450
Korean J Thorac Cardiovasc Surg. 2020 Oct 05;53(5):317-320. doi: 10.5090/kjtcs.19.098.

Pulmonary carcinoids are relatively rare tumors with low metastatic potential. Pleural carcinomatosis of a bronchial carcinoid has only been reported in 4 cases. Due to the rarity of this condition, there are no guidelines for its treatment or management....
