AMBIGUITY OF LOCI DURING HLA-TYPING ON SSO TECHNOLOGY AND ATTEMPT TO RESOLVE THEM

open access: yesВестник трансплантологии и искусственных органов, 2010
Sequence specific oligonucleotides typing was used to identify human leukocyte antigen (HLA)-A, B, DRB1 alleles from 705 recruited volunteers with Volga Federal District for unrelated hematopoietic stem cell registry and 155 of their number at locus HLA ...

On the Relations Between Excess Fraction, Attributable Fraction, and Etiologic Fraction [PDF]

open access: yesAmerican Journal of Epidemiology, 2012
It has been noted that there is ambiguity in the expression "attributable fraction," and epidemiologic literature has drawn a distinction between "excess fraction" and "etiologic fraction." These quantities do not necessarily approximate one another, and the etiologic fraction is not generally estimable without strong biologic assumptions.

Fluorescent Probes for Exploring Plant Cell Wall Deconstruction: A Review

open access: yesMolecules, 2014
Plant biomass is a potential resource of chemicals, new materials and biofuels that could reduce our dependency on fossil carbon, thus decreasing the greenhouse effect. However, due to its chemical and structural complexity, plant biomass is recalcitrant

FRET-SLiM on native autofluorescence: a fast and reliable method to study interactions between fluorescent probes and lignin in plant cell wall

open access: yesPlant Methods, 2018
Background Lignocellulosic biomass is a complex network of polymers making the cell walls of plants. It represents a feedstock of sustainable resources to be converted into fuels, chemicals and materials.

Fractional Coins and Fractional Derivatives [PDF]

open access: yesAbstract and Applied Analysis, 2013
This paper discusses the fundamentals of negative probabilities and fractional calculus. The historical evolution and the main mathematical concepts are discussed, and several analogies between the two apparently unrelated topics are established. Based on the new conceptual perspective, some experiments are performed shading new light into possible ...

Fractional free space, fractional lenses, and fractional imaging systems [PDF]

open access: yesJournal of the Optical Society of America A, 2003
Continuum extensions of common dual pairs of operators are presented and consolidated, based on the fractional Fourier transform. In particular, the fractional chirp multiplication, fractional chirp convolution, and fractional scaling operators are defined and expressed in terms of their common nonfractional special cases, revealing precisely how they ...

A fractional calculus on arbitrary time scales: Fractional differentiation and fractional integration [PDF]

open access: yesSignal Processing, 2015
We introduce a general notion of fractional (noninteger) derivative for functions defined on arbitrary time scales. The basic tools for the time-scale fractional calculus (fractional differentiation and fractional integration) are then developed. As particular cases, one obtains the usual time-scale Hilger derivative when the order of differentiation ...
