this review provides the basic principle and rational for roc analysis of rating and continuous diagnostic test results versus a gold standard. derived indexes of accuracy, in particular area under the curve (auc) has a meaningful interpretation for disease classification from healthy subjects. the methods of estimate of auc and its testing in single diagnostic test and also comparative studies...

The braid monodromy factorization of the branch curve of a surface of general type is known to be an invariant that completely determines the diffeomorphism type of the surface (see [2]). Calculating this factorization is of high technical complexity; computing the braid monodromy factorization of branch curves of surfaces uncovers new facts and invariants of the surfaces. Since finding the bra...

We propose a symbolic algorithm for detecting the variations in the topological and algebraic properties of the intersection curve of two moving quadrics in PR(real projective 3-space). The core of our algorithm computes all the instants when the intersection curve of two moving quadrics changes type using resultants and Jordan forms. These instants partition the time axis into intervals within...

PURPOSE To determine if the curve length, curve form, and location of the lower-end vertebra can identify the type of scoliosis. METHODS Standing posteroanterior and lateral radiographs of 78 women and 27 men with scoliosis aged 8 to 32 years were retrospectively analysed. Parameters measured were (1) the curve length (the number of vertebrae in the main curve), (2) the curve form (C-form, in...

We present rotation curves derived from H i observations for a sample of 62 galaxies that have been observed as part of the Westerbork H i Survey of Spiral and Irregular Galaxies (WHISP) project. These rotation curves have been derived by interactively fitting model data cubes to the observed cubes. This procedure takes the rotation curve shape, the H i distribution, the inclination, and the si...

CONTEXT Real-time polymerase chain reaction technologies have replaced many of the more labor-intense methods in the molecular diagnostics laboratory. Similarly, melt curve analysis can provide a rapid means of mutation screening. OBJECTIVE To determine if real-time polymerase chain reaction and melt curve analysis using the SmartCycler II could be used as a screening tool for 3 common mutati...
