ELECTROMAGNETIC FIELDS ON FRACTALS [PDF]
Modern Physics Letters A, 2006 Fractals are measurable metric sets with non-integer Hausdorff dimensions. If electric and magnetic fields are defined on fractal and do not exist outside of fractal in Euclidean space, then we can use the fractional generalization of the integral Maxwell equations. The fractional integrals are considered as approximations of integrals on fractals. We

High frequency characterization of Galfenol minor flux density loops
AIP Advances, 2017 This paper presents the first measurement of ring-shaped Galfenol’s high frequency-dependent minor flux density loops. The frequencies of applied AC magnetic field are 1k, 5k, 10k, 50k, 100k, 200k, 300k, 500 kHz. The measurements show that the cycle area

Sleep EEG-Based Approach to Detect Mild Cognitive Impairment
Frontiers in Aging Neuroscience, 2022 Mild Cognitive Impairment (MCI) is an early stage of dementia, which may lead to Alzheimer’s disease (AD) in older adults. Therefore, early detection of MCI and implementation of treatment and intervention can effectively slow down or even inhibit the ...

Electromagnetic field near cosmic string [PDF]
, 2006 The retarded Green function of the electromagnetic field in spacetime of a straight thin cosmic string is found. It splits into a geodesic part (corresponding to the propagation along null rays) and to the field scattered on the string.

A comparision of Hodgkin-Huxley and soliton neural theories [PDF]
Advances in Radio Science, 2010 Hodgkin and Huxley were the pioneers to abstract biological neuron as an electric circuit and nerve signal as the voltage impulse. The Hodgkin-Huxley theory (Hodgkin and Huxley, 1952) has set the direction and defined the goals for much of the ensuing ...

Maxwell Fields in Spacetimes Admitting Non-Null Killing Vectors [PDF]
, 1993 We consider source-free electromagnetic fields in spacetimes possessing a non-null Killing vector field, $\xi^a$. We assume further that the electromagnetic field tensor, $F_{ab}$, is invariant under the action of the isometry group induced by $\xi^a ...
