Microarray RNA Quantification Assay for Large-Scale Nanosamples Analysis

open access: yesBioTechniques, 2001
We have developed a convenient and sensitive method for the quantification of RNA in samples from microbiopsies. This procedure is especially suitable for quantitating very small amounts of RNA in largescale biological samples.

Fourier restriction to polynomial curves I: a geometric inequality [PDF]

open access: yes, 2010
We prove a Fourier restriction result for general polynomial curves in Rd. Measuring the Fourier restriction with respect to the affine arclength measure of the curve, we obtain a universal estimate for the class of all polynomial curves of bounded ...

Correcting principal component maps for effects of spatial autocorrelation in population genetic data

open access: yesFrontiers in Genetics, 2012
In many species, spatial genetic variation displays patterns of isolation-by-distance. Characterized by locally correlated allele frequencies, these patterns are known to create periodic shapes in geographic maps of principal components which confound ...

Investigating the Stationarity Properties of Oil Consumption: an Empirical Analysis for OECD Countries

open access: yesİktisat Politikası Araştırmaları Dergisi, 2022
In a changing and developing world, production activities are dependent on energy resources. A significant part of the energy needed in the world is obtained from fossil fuels.

Random fractional Fourier transform : stochastic perturbations along the axis of propagation [PDF]

open access: yes, 1999
The fractional Fourier transform (FRT) is known to be optically implementable with use of a medium with a perfect radial quadratic-index profile. Using the quantum-mechanical operator formalism, we examine the effects on the FRT action of such a medium

Quantification of Ethnic Differences in Facial Profile

open access: yesAustralasian Orthodontic Journal, 1997
The concept of facial aesthetics is becoming increasingly important and with the expanding application of orthodontic, orthognathic, plastic and reconstructive techniques to patients from continually diversifying ethnic backgrounds, it is timely that ...

New therapeutic approaches for treatment of tularaemia: a review

open access: yesFrontiers in Cellular and Infection Microbiology, 2014
Antibiotic treatment of tularaemia is based on a few drugs, including the fluoroquinolones, the tetracyclines and the aminoglycosides. Because no effective and safe vaccine is currently available, tularaemia prophylaxis following proven exposure to F ...

Application of Shape Analyses to Recording Structures of Marine Organisms for Stock Discrimination and Taxonomic Purposes

open access: yesFrontiers in Marine Science, 2021
Morphometric analysis of biogenic recording structures within marine organisms has applications in stock assessment, taxonomics, and ecomorphological studies, with shape variation markedly influenced by both genetics and the surrounding environment ...
