Effects of Flecainide on Defibrillation Threshold in Pigs
Journal of Cardiovascular Pharmacology, 1993Flecainide has been reported to decrease defibrillation efficacy in pentobarbital-anesthetized dogs. Conversely, flecainide did not alter defibrillation energy requirements in halothane-anesthetized pigs. We wished to determine whether these discrepancies were related to defibrillation technique, interaction with the anesthetic regimen, or animal ...

On the threshold effect in the estimation of chaotic sequences
The 22nd Convention on Electrical and Electronics Engineers in Israel, 2002., 2003Chaotic sequences and chaotic dynamic systems are attractive candidates for use in signal modelling, synthesis, and analysis as well as in communications applications. In most of the above applications, there is a frequent need to estimate the chaotic sequence from noisy observations.

String unification and threshold effects
Physical Review D, 1988String unification is affected by string loop corrections if the corresponding string theory is strongly coupled. We study some properties of string loop thresholds and the implications for the phenomenological renormalization-group analysis.

Supra‐threshold contrast matching and the effects of contrast threshold and age
Clinical and Experimental Optometry, 2007The effects of age on contrast threshold are well known but little is known about its effect on supra-threshold contrast perception. This study examines supra-threshold contrast matching and the effects of age in naïve observers.Two age groups (from 20 to 50 years with 14 subjects and 51 years and older with 15 subjects) participated in the study ...

The Effect of Thiabendazole on Pain Threshold
Acta Pharmacologica et Toxicologica, 1985Abstract:Thiabendazole significantly increased the reaction time to thermal stimulus. However, in mice treated with morphine, the reaction time was not in any way different from those treated with combined doses of thiabendazole and morphine. Thiabendazole was found to have an antinociceptive action. The protective dose for 50% of animal (ED50) against

Effects of rod activity on color threshold
Vision Research, 1976Abstract The specific thresholds of blue and red lights, measured extrafoveally in a dark-adapted state, were obtained at intensities below the cone-plateau level of the long-term dark-adaptation curve, while the specific thresholds of green lights were obtained at intensities above the cone-plateau level.

Resonances and Threshold Effects
1980Much of the energy-dependent structure observed in low-energy electron scattering arises from resonances and threshold effects. Resonances are due to nearly bound states of the (N + 1)-electron system of target atom and external electron. In a time-dependent formalism, such a state decays with a finite lifetime if it interacts with states in an ...
