On Quantitizing [PDF]

open access: yesJournal of Mixed Methods Research, 2009
Quantitizing, commonly understood to refer to the numerical translation, transformation, or conversion of qualitative data, has become a staple of mixed methods research. Typically glossed are the foundational assumptions, judgments, and compromises involved in converting disparate data sets into each other and whether such conversions advance inquiry.

Quantitative languages [PDF]

open access: yesACM Transactions on Computational Logic, 2008
Quantitative generalizations of classical languages, which assign to each word a real number instead of a Boolean value, have applications in modeling resource-constrained computation. We use weighted automata (finite automata with transition weights) to define several natural classes of quantitative languages over finite and infinite words; in ...

Quantitative testing [PDF]

open access: yesProceedings of the 8th ACM international conference on Embedded software, 2008
We investigate the problem of specification based testing with dense sets of inputs and outputs, in particular with imprecision as they might occur due to errors in measurements, numerical instability or noisy channels. Using quantitative transition systems to describe implementations and specifications, we introduce implementation relations that ...

Quantitative Acoustophoresis

open access: yesACS Nanoscience Au, 2022
Studying cellular mechanics allows important insights into its cytoskeletal composition, developmental stage, and health. While many force spectroscopy assays exist that allow probing of mechanics of bioparticles, most of them require immobilization of and direct contact with the particle and can only measure a single particle at a time.

Influence of Pre-analytical Factors on Thymus- and Activation-regulated Chemokine Quantitation in Plasma [PDF]

open access: yes, 2015
Thymus- and activation-regulated chemokine (TARC) in serum/plasma associates with the disease activity of atopic dermatitis (AD), and is a promising tool for assessing the response to the treatment of the disease.

A liquid chromatography-mass spectrometry workflow for in-depth quantitation of fatty acid double bond location isomers

open access: yesJournal of Lipid Research, 2021
Tracing compositional changes of fatty acids (FAs) is frequently used as a means of monitoring metabolic alterations in perturbed biological states. Given that more than half of FAs in the mammalian lipidome are unsaturated, quantitation of FAs at a ...

Simultaneous LC/MS/MS quantification of eight apolipoproteins in normal and hypercholesterolemic mouse plasma[S]

open access: yesJournal of Lipid Research, 2019
Apolipoproteins are major structural and functional constituents of lipoprotein particles. As modulators of lipid metabolism, adipose tissue biology, and energy homeostasis, apolipoproteins may serve as biomarkers or potential therapeutic targets for ...

Real-Time qPCR as a Method for Detection of Antibody-Neutralized Phage Particles

open access: yesFrontiers in Microbiology, 2017
The most common method for phage quantitation is the plaque assay, which relies on phage ability to infect bacteria. However, non-infective phage particles may preserve other biological properties; specifically, they may enter interactions with the ...
