Approximate functional dependencies are used in many emerging application domains, such as the identification of data inconsistencies or patterns of semantically related data, query rewriting, and so forth. They can approximate the canonical definition of functional dependency (fd) by relaxing on the data comparison (i.e., by considering data similarity rather than equality), on the extent (i.e...

When individuals' fitnesses depend on the genetic composition of the population in which they are found, selection is then frequency dependent. Frequency-dependent selection (FDS) is often invoked as a heuristic explanation for the maintenance of large numbers of alleles at a locus. The pairwise interaction model is a general model of FDS via intraspecific competition at the genotypic level. He...

Codd’s relational model describes just one possible world. To better cope with incomplete information, extended database models allow several possible worlds. Vague tables are one such convenient extended model where attributes accept sets of possible values (e.g., the manager is either Jill or Bob). However, conceptual database design in such cases remains an open problem. In particular, there...

BACKGROUND Traumatic amputation of the digit requiring revision amputation at the level of the proximal phalanx provides the opportunity to improve flexor function via tenodesis of the remaining flexor digitorum superficialis (FDS) tendon. Salvage of the remaining FDS and performing flexor tenodesis to the proximal phalanx allows increased flexion at the metacarpophalangeal (MCP) joint. METHO...

BACKGROUND A foot drop stimulator (FDS) is a rehabilitation intervention that stimulates the common peroneal nerve to facilitate ankle dorsiflexion at the appropriate time during post-stroke hemiplegic gait. Time-frequency analysis (TFA) of non-stationary surface electromyograms (EMG) and spectral variables such as instantaneous mean frequency (IMNF) can provide valuable information on the long...

    The solubility enhancement of poorly soluble compounds is an important task in pharmaceutical technology as it leads to better bioavailability and a more efficient application. Fused dispersions (FDs) of simvastatin (SIM) using PEO-PPO block copolymer were prepared which paved the way for the formation of an amorphous product with enhanced dissolution and bioavailability. The accumulative s...

Functional dependencies (FDs) and inclusion dependencies (INDs) are the most fundamental integrity constraints that arise in practice in relational databases. In this paper we address the issue of normalisation in the presence of FDs and INDs and in particular the semantic justiication for Inclusion Dependency Normal Form (IDNF), a normal form which combines Boyce-Codd normal form with the rest...

In this study, fire in a short 2-lane single-directional road tunnel with two different traffic situations is considered and the impact of spread of fire and smoke on people evacuation is investigated. The FDS+Evac system used comprises of FDS (Fire Dynamics Simulator), an advanced CFD (Computational Fluid Dynamics) fire field model supplemented by agent-based FDS evacuation model, Evac. Evac i...

Two enzyme-linked immunosorbent assay (ELISA) kits were evaluated for detection of porcine reproductive and respiratory syndrome (PRRS) antibodies in pooled sera and filter discs (FDs). Elution and incubation procedures and positive thresholds for both ELISAs were determined using FDs collected from sixty non-infected pigs and five pigs with low PRRS-antibody titres. Eighty paired samples (seru...
