Optociliary Shunt Vessel: An Ancillary Ophthalmic Sign Harbingering Optic Nerve Sheath Meningioma

Nepal Journal of Neuroscience, 2019
A 61-year-old male presented with gradual loss of vision in his right eye for one year at neuro ophthalmology clinic. On clinical examination, his visual acuity was perception of light and intraocular pressure was 12 mm of Hg in right eye.

Structural Elements Energy Losses of Electrical Equipment due to a Violation of Symmetry of Power Transmission Mode Parameters

Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика
The asymmetry of power transmission mode parameters due to the induction current effect on structural elements of electrical equipment is investigated. Three-phase AC current produces a rotating magnetic field that affects the power transmission system ...

Common features of vortex structure in long exponentially shaped Josephson junctions and Josephson junctions with inhomogeneities

, 2006
We study vortex structure in three different models of long Josephson junctions: exponentially shaped Josephson junction and Josephson junctions with resistor and shunt inhomogeneities in barrier layer.

Determining the Positions and Dimensions of Horizontal Magnetic Shunts in Transformer Tank Walls Using Parametric Analyses Based on the Finite Element Method

Applied Sciences
Magnetic shunts efficiently mitigate losses caused by leakage currents in the tank walls of power transformers. Transformer manufacturers frequently utilize vertical magnetic shunts positioned on the inside surfaces of the transformer tank walls.

Shunt-capacitor-assisted synchronization of oscillations in intrinsic Josephson junctions stack

, 2010
We show that shunt capacitor stabilizes synchronized oscillations in intrinsic Josephson junction stacks biased by DC current. This synchronization mechanism has an effect similar to the previously discussed radiative coupling between junctions, however,
