It is well established that generalized epileptiform EEG discharges unaccompanied by overt clinical change may nevertheless be associated with transitory cognitive impairment (TCI) detectable by appropriate psychological testing. However, the tests employed in most research studies of this phenomenon are of little use for routine clinical application. They are suitable for administration only o...

We present an adaptive animation method for electrical discharges. Electric discharges can be simulated using the dielectric breakdown model. Regular discretization of the governing Laplace equation leads to huge equation systems, and the computational cost of solving the equations quickly becomes prohibitive at high resolutions, especially for simulations in 3D. In contrast, our method discret...

During the ageing of in-service medium voltage equipment, electrical losses are mainly due to partial discharges. These partial discharges can lead to the electrical failure of industrial equipment [1]. Partial discharges include (i) bulk discharges occurring in insulating material voids, (ii) corona discharges affecting or not the insulator and (iii) surface discharges developing on an insulat...

In this paper, the results obtained from lab tests on twisted pairs subjected to different voltage waveforms and atmospheric conditions are used propose how modify IEC Std. 60034-18-41. The goal is make standard suitable for More Electrical Aircraft (MEA). show that it initially necessary screen out materials through simple tests. enhancement factors temperature can be modified consider reduced...

Technical problems have hampered the study of sleep in teleosts. The electrical discharges of Gymnotus carapo L. (Gymnotidae: Gymnotiformes) were monitored to evaluate their ease and reliability as parameters to study sleep. The discharges were detected by electrodes immersed in a glass aquarium and were recorded on a conventional polygraph. G. carapo showed conspicuous signs of behavioral slee...

BACKGROUND Cardiomyocytes cytoarchitecture changes caused by transthoracic countershocks have been focused recently. We aimed to evaluate the effects of electrical discharge application in the mitochondria structure in atrial myocardium of rats. METHODS An electrical cardioverter was adapted to small rodent animals for our research. Electrical discharges were applied to the precordial region ...

Mechanisms underlying seizure generation are traditionally thought to act over seconds to minutes before clinical seizure onset. We analyzed continuous 3- to 14-day intracranial EEG recordings from five patients with mesial temporal lobe epilepsy obtained during evaluation for epilepsy surgery. We found localized quantitative EEG changes identifying prolonged bursts of complex epileptiform disc...
