OBJECTIVE Better definition of normal amplitude asymmetry values on the classical EEG frequency bands. RESULTS EEG amplitude asymmetry index (AAI) is physiologically low in normal adults, differences usually lesser than 7%. CONCLUSION Persistent or intermittent amplitude asymmetry regional differences higher than 7% may be suggestive of pathology after adequate correlation with clinical dat...

As a planet transits the face of a star, it accelerates along the line of sight. The changing delay in the propagation of photons produces an apparent deceleration of the planet across the sky throughout the transit. This persistent transverse deceleration breaks the time-reversal symmetry in the transit light curve of a spherical planet in a circular orbit around a perfectly symmetric star. Fo...

The present study was undertaken to assess the skeletal craniofacial asymmetry in South Indian population by a posteroanterior cephalometric radiographic method. The skeletal craniofacial structures on one side of the face were compared with that of the other, by drawing various triangles representing different craniofacial regions. The sample consisted of 60 subjects (30 males and 30 females) ...

Variations of power and ground levels affect VLSI circuit performance. Trends in device technology and in packaging have necessitated a revision in conventional delay models. In particular, simple scalable models are needed to predict delays in the presence of uncorrelated power and ground noise. In this paper, we analyze the effect of such noise on signal propagation through a buffer and prese...

We analyse the average case complexity of evaluating all preexes of an input vector over a given semigroup. As computational model circuits over the semigroup are used and a complexity measure for the average delay of such circuits, called time, is introduced. Based on this notion, we then deene the average case complexity of a computational problem for arbitrary input distributions. For highly...

We analyze a semiexplicit time discretization scheme of first order for poroelasticity with nonlinear permeability provided that the elasticity model and flow equation are only weakly coupled. The approach leads to decoupling equations and, at same time, linearizes nonlinearity without need further inner iteration steps. Hence, computational speedup is twofold loss in convergence rate. prove op...

We demonstrate in vivo optical coherence tomography using a Fourier-domain optical delay line constructed with a commercially available polygonal scanner. The 20-faceted polygonal mirror array, capable of scanning at rates up to 15 kHz, is implemented at 4 kHz to acquire 500 x 500 pixel images at 8 frames/s with a signal-to-noise ratio of 80 dB. Features of this delay line include scalability t...

People are impatient and discount future rewards more when they are asked to delay consumption than when they are offered the chance to accelerate consumption. The three experiments reported here provide a process-level account for this asymmetry, with implications for designing decision environments that promote less impulsivity. In Experiment 1, a thought-listing procedure showed that people ...

introduction: due to the complexity of facial asy-mmetry, the diagnosis of different aspects of asymmetry via conventional radiographs is not precise. in this study, we investigated findings of facial asymmetry by using cone- beam computed tomography (cbct) images. materials and methods: in this descriptive study, we evaluated cbct findings of 18 patients i.e. a group of 14 females and 4 males ...
