Work in Artificial Intelligence often involves search algorithms. In many complicated problems, however, local search algorithms may fail to converge into global optimization and global search procedures are needed. In this paper, we investigate the Fourier Amplitude Sensitivity Test (FAST) as an example of a global sensitivity analysis tool for complex, non-linear dynamical systems. FAST was o...

Capsaicin has been used as a tussive agent in studies in adults to determine cough receptor sensitivity. The aim of this study was to determine the tolerance, repeatability and influence of inspiratory flow on the capsaicin cough receptor sensitivity test in children. Thirty children (mean age 11 yrs; range 6-16 yrs) were tested on two different days, to determine the lowest concentration of ca...

A new test for the detection of antibodies to gliadin in the sera of children who are gluten sensitive is described. This test is based on the observation that wheat protein binds selectively to connective tissue fibres in cryostat sections of mammalian tissues. Sera containing antibodies to gliadin give a reticulin pattern of staining on section pretreated with wheat gliadin if tested by indir...

We read with great interest the recent article by Teichmann et al. [1], who presented results of the Free and Cued Selective Reminding Test (FCSRT) accuracy to differentiate typical (amnestic) Alzheimer’s disease (AD) from other neurodegenerative diseases. The authors assessed FCSRT in a group of 992 individuals, most of them with the diagnosis of AD, and stated that FCSRT would have a sensitiv...

A commonly used estimate of a screening test's sensitivity, based on the prevalence at screening and the incidence of interval cancers, is shown to be logically unsound and quantitatively poor. An alternative simple estimate is proposed, based only on incidence rates.

While technology is changing the face of the world, it itself is changing by leaps and bounds; there is a continuing trend to put more functionality on the same piece of silicon. Without major changes in the CMOS technology, it has been shown that the scaling of devices has signi cant impact on the e ectiveness of Iddq testing. The sensitivity of Iddq testing to individual device parameters is ...

BACKGROUND A vestibulospinal test known as the Fukuda stepping test (FST) has been suggested to be a measure of asymmetrical labyrinthine function. However, an extensive review of the performance of this test to identify a peripheral vestibular lesion has not been reported. PURPOSE The purpose of this study was to evaluate the sensitivity and specificity of the standard FST and a head shaking...
