Whole-body plethysmograph measurements and challenge inhalation of carbachol were combined to assess asthmatic changes longitudinally. Airway conductance proved to be relatively stable over a 10-week period in 3 normal subjects. Five asthmatics showed periodically lower conductance and greater variability. Periods of low conductance at times could be observed to precede other manifestations of ...

Standing balance control relies on multisensory feedback, but little is known about the influence of periodically varying sounds on this process. The level of sensorimotor activation has been shown to be highly correlated with the concept of musical groove. We presented musical stimuli with high and low groove ratings to participants (N=40) as center of pressure (CoP) was recorded using a force...

A periodically poled lithium niobate (PPLN) crystal has been used as an efficient source of non-collinearly generated polarization-entangled photon pairs at 810 and 1550 nm. The PPLN crystal was endowed with a specially designed poling pattern and the entangled photons were generated via the nonlinear optical process of spontaneous parametric down conversion (SPDC). A novel design based on over...

The orbit determination of a satellite in a geostationary orbit is usually based on optical observations. Telescopes all around the Earth are observing the geostationary ring to obtain periodically new measurements in order to update the estimation of the objects’ orbits. One critical aspect of the orbit determination process is the initial orbit determination because no a priori information ar...

Abstract The periodic behavior of real data can be manifested in the time series or its characteristics. One characteristics that often manifests is sample autocovariance function. In this case, periodically correlated (PC) considered. main models exhibits PC property autoregressive (PARMA) model considered as generalization classical moving average (ARMA) process. However, when one considers d...

Various studies have investigated the temporal aspects of non­ native speech and their relation to perceived fluency, because fluency constitutes an important aspect of second language proficiency. For this purpose it is important to determine which measures are most strongly correlated with perceived fluency and how these measures vary. In the present study objective measures related to percei...
