This study evaluates the discriminative power of sequential spectrum analysis of the short-term electrocardiogram (ECG) time series in separating normal and subjects with life threatening arrhythmias like, ventricular tachycardia/fibrillation (VT/VF). The raw ECG time series is transformed into a series of binary symbols and the binary occupancy or relative distribution of mono-sequences (i.e. ...

Polymorphic Amplified Typing Sequences (PATS) is a PCR-based Escherichia coli O157 (O157) strain typing system. Here, we show that PATS compares excellently with Pulsed-Field Gel Electrophoresis (PFGE) in that both methods cluster geographically diverse O157 isolates similarly. Comparative analysis of the results obtained in this simulated "blind" study attests to the discriminating power and a...

The identification of drugs by the combination of two-dimensional HPTLC and remission spectrometry is described. The discriminating power and information content of this combination are calculated and compared with the corresponding values of GC/MS. Advantages and disadvantages of HPTLC and applications to some drugs are mentioned.

Background/Introduction Predicting major adverse events and death in patients undergoing cardiac surgery is based on clinical risk scores such as Euroscore. This score has a moderate power for discriminating morbidity. Natriuretic peptides are wellestablished biomarkers in numerous clinical settings, prognostic, diagnostic and treatment of cardiac failure. In cardiac surgical patients the role ...

In this paper, we compare merging operators in possibilistic logic. We first propose an approach to evaluating the discriminating power of a merging operator. After that, we analyze the computational complexity of existing possibilistic merging operators. Finally, we consider the compatibility of possibilistic merging operators with propositional merging operators.

Blood metabolites can be detected as low-mass ions (LMIs) by mass spectrometry (MS). These LMIs may reflect the pathological changes in metabolism that occur as part of a disease state, such as cancer. We constructed a LMI discriminant equation (LOME) to investigate whether systematic LMI profiling might be applied to cancer screening. LMI information including m/z and mass peak intensity was o...

BACKGROUND The Bath Ankylosing Spondylitis Functional Index (BASFI) has been commonly used in rheumatology to quantify functional disability in patients with ankylosing spondylitis (AS). Our aim was to evaluate the discriminating power of BASFI and determine the best cutoff score of this index in the general population compared with AS patients. METHODS A cross-sectional study that included 2...
