Qualitative and Quantitative Analysis of Mycotoxins [PDF]

open access: yesComprehensive Reviews in Food Science and Food Safety, 2009
ABSTRACT:  Mycotoxin toxicity occurs at very low concentrations, therefore sensitive and reliable methods for their detection are required. Consequently, sampling and analysis of mycotoxins is of critical importance because failure to achieve a suitable verified analysis can lead to unacceptable consignments being accepted or satisfactory shipments ...

Qualitative analysis of string cosmologies [PDF]

open access: yesPhysical Review D, 1999
A qualitative analysis is presented for spatially flat, isotropic and homogeneous cosmologies derived from the string effective action when the combined effects of a dilaton, modulus, two-form potential and central charge deficit are included. The latter has significant effects on the qualitative dynamics.

Analysis of Qualitative Variables [PDF]

open access: yes, 1974
A variety of qualitative dependent variable models are surveyed with attention focused on the computational aspects of their analysis. The models covered include single equation dichotomous models; single equation polychotomous models with unordered, ordered, and sequential variables; and simultaneous equation models.

Qualitative Comparative Analysis

open access: yes, 2022
Qualitative Comparative Analysis (QCA) is a set-theoretic comparative method that treats cases as configurations of conditions, aiming to identify those conditions and/or combinations that are necessary and/or sufficient for an outcome. This chapter opens with a review of how the method has been applied empirically in the fields of Foreign Policy ...

Fibromyalgia Flares: A Qualitative Analysis [PDF]

open access: yesPain Medicine, 2015
Patients with fibromyalgia report periods of symptom exacerbation, colloquially referred to as "flares" and despite clinical observation of flares, no research has purposefully evaluated the presence and characteristics of flares in fibromyalgia. The purpose of this qualitative study was to describe fibromyalgia flares in a sample of patients with ...

CEGAR for Qualitative Analysis of Probabilistic Systems [PDF]

open access: yes, 2014
We consider Markov decision processes (MDPs) which are a standard model for probabilistic systems. We focus on qualitative properties for MDPs that can express that desired behaviors of the system arise almost-surely (with probability 1) or with positive probability. We introduce a new simulation relation to capture the refinement relation of MDPs with
