We propose a new automaton model, called quantified data automata over words, that can model quantified invariants over linear data structures, and study their theory, including closure properties, canonical minimality, and decidability of emptiness. We build poly-time active learning algorithms for them, where the learner is allowed to query the teacher with membership and equivalence queries....

Abstract Using qualitative data analysis (QDA) to perform domain and modeling has shown great promise. Yet, the evaluation of such approaches been limited single-case case studies. While these exploratory cases are valuable for an initial assessment, efficacy QDA solve suggested problems is restricted by common study research design. our own method, called QDAcity-RE, as example, we present in-...

BACKGROUND So far, non-invasive diagnostic approaches such as ultrasound, magnetic resonance imaging, or blood tests do not have sufficient diagnostic power for endometriosis disease. Lack of a non-invasive diagnostic test contributes to the long delay between onset of symptoms and diagnosis of endometriosis. OBJECTIVE The present study focuses on the identification of predictive biomarkers i...

This study presents ATR-FTIR (attenuated total reflectance Fourier-transform infrared) spectral analysis of ex vivo oesophageal tissue including all classifications to adenocarcinoma (OAC). The article adds further validation previous human studies identifying the potential for spectroscopy in differentiating among classes transformation OAC. Tissue used principal component quadratic discrimina...

Classification of Indian stock market data has always been a certain appeal for researchers. In this paper, first time combination of three supervised machine learning algorithms, classification and regression tree (CART) , linear discriminant analysis (LDA) and quadratic discriminant analysis (QDA) are proposed for classification of Indian stock market data, which gives simple interpretation o...

Qualitative data analysis (QDA) is often depicted as a linear process that employs an organised structure to derive themes inductively or deductively. However, I realised the “messiness” of during my doctoral studies on primary teachers’ use digital technologies in ESL classrooms Maldivian schools. My own experience revealed QDA nonlinear, iterative and recursive process. Adopting phenomenologi...

Ethanol enhancement of 5-hydroxytryptamine (5-HT)(3A) receptor-mediated responses may have important consequences in the intoxicating and addictive properties of ethanol. Although the exact mechanism is unknown, ethanol-mediated enhancement of 5-HT(3) receptor current has been proposed to occur due to stabilization of the open-channel state. It has not been possible to directly measure the open...

The title compound, C(11)H(7)NO(4)·H(2)O, contains a 3-carb-oxy-quinolin-1-ium-2-carboxyl-ate (qda) zwitterion and one water mol-ecule. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules into inversion dimers, and these dimers are further connected by O-H⋯O hydrogen bonds into a three-dimensional supra-molecular architecture. In addition, π-π inter-actions occur between pyridine ...

The quinone Diels-Alder (QDA) reaction has considerable synthetic power in terms of introducing structural complexity. As a consequence, the corresponding transform is a worthwhile goal in retrosynthetic analysis and therefore has been implemented as a transform-goal, or long-range, strategy in the LHASA program. The implemented strategy allows LHASA to convert any suitable target containing th...
