Conditional Functional Dependencies (CFDs) are Functional Dependencies (FDs) that hold on a fragment relation of the original relation. In this paper, we show the hierarchy between FDs, CFDs and Association Rules (ARs): FDs are the union of CFDs while CFDs are the union of ARs. We also show the link between Approximate Functional Dependencies (AFDs) and approximate ARs. In this paper, we show t...

Binding energy spectra and orbital momentum distributions of the two most stable conformers of L-alanine are investigated. Molecular properties such as geometry and dipole moments agree well with available experimental and previous theoretical investigations. Dual space analysis is employed to study the binding energy spectra in coordinate space based on B3LYP/TZVP density functional calculatio...

Introduction: Functional gastrointestinal disorders (FGID) are non-fatal, unknown etiology disorders with absence of a structural or biochemical explanation and accounting for up to 50% of gastroenterology referrals. Infant regurgitation, rumination and cyclic vomiting constitute the vomiting disorders. Abdominal pain disorders are classified as: functional dyspepsia, irritable bowel syndrome (...
