A communal dormitory of male orchid bees, Euglossa melanotricha Moure, was monitored over a one-year period, when they passed the night in the fronds of a Serpocaulon triseriale (Polypodiaceae) fern. The bees used the same fronds continuously, moving to neighboring fronds as senescence set in. As many as 49 males were observed together on any one night,(More)
Cement-cement interfaces were created under simulated operating-room conditions. In order to analyze the effect of time to apposition on interface strength, two cement surfaces were brought together 1, 2, 4, and 6 min after 1 min of mixing and 45 s of waiting. Cement-cement interface strength was evaluated with the use of a three-point bending to failure(More)
The present investigation documents the electrophysiological occurrence of multisensory stochastic resonance in the human visual pathway elicited by tactile noise. We define multisensory stochastic resonance of brain evoked potentials as the phenomenon in which an intermediate level of input noise of one sensory modality enhances the brain evoked response(More)
40 The present investigation documents the electrophysiological occurrence of 41 multisensory stochastic resonance in the human visual pathway elicited by tactile 42 noise. We define multisensory stochastic resonance of brain evoked potentials as 43 the phenomenon in which an intermediate level of input noise of one sensory 44 modality enhances the brain(More)
Effect of mechanical tactile noise on amplitude of visual evoked potentials: multisen-sory stochastic resonance.—The present investigation documents the electrophysiological occurrence of multisensory stochastic resonance in the human visual pathway elicited by tactile noise. We define multisensory stochastic resonance of brain evoked potentials as the(More)
