Negative sequence voltages in spontaneous atrial fibrillation or flutter

International Journal of Cardiology, 2008
The patho-physiology of initiation of atrial fibrillation (af) or flutter (AF) is not known. Would it be possible that the real explanation is hidden in physics territory but not in medicine? Could it be possible that the heart behaves like a biological generator in physics?

Negative priming in sequence learning

2007
We investigated negative priming (NP) in sequence learning, as demonstrated by Cock et al. (2002). The NP effect in sequence learning refers to the observation that Serial Reaction Time performance becomes impaired when participants respond to a sequence they were previously ignoring.

Omnidirectional Single-negative Gap and in Fibonacci Sequences Composed of Single-negative Materials

International Journal of Infrared and Millimeter Waves, 2007
The band structures of Fibonacci sequence composed of single-negative materials are studied with a transfer matrix method. A new type of omnidirectional single-negative gaps is found in the Fibonacci sequence. In contrast to the Bragg gaps, such an omnidirectional single-negative gap is insensitive to the incident angles and polarization, and is ...

Negative-sequence currents for line-to-line faults

Electrical Engineering, 1953
THE RECENT REVISION of the American Standards Association Standard for Rotating Electrical Machinery, C50, short-circuit clause specifies requirements for synchronous generators during 3-phase, line-to-ground, and line-to-line short circuits. A generator operating at rated kilovolt-amperes and power factor, with fixed excitation at 5-per-cent ...
