Decayless kink oscillations of solar coronal loops are studied in terms a low-dimensional model based on randomly driven Rayleigh oscillator with coefficients experiencing random fluctuations. The considers as natural modes loops, decaying by linear resonant absorption. damping is counteracted motions the loop footpoints and interaction external quasi-steady flows In other words, combines self-...

Grid cells in the rodent medial entorhinal cortex exhibit remarkably regular spatial firing patterns that tessellate all environments visited by the animal. Two theoretical mechanisms that could generate this spatially periodic activity pattern have been proposed: oscillatory interference and continuous attractor dynamics. Although a variety of evidence has been cited in support of each, some a...

Deep brain stimulation (DBS) is a promising approach in treatment-resistant depression (TRD). TRD is associated with problems in interpersonal relationships, which might be linked to impaired empathy. Here, we investigate the influence of DBS in the subgenual anterior cingulate cortex (sgACC) on empathy in patients with TRD and explore the pattern of oscillatory sgACC activity during performanc...

We have analytically obtained the theoretical results for Rayleigh-Sommerfeld (R-S) scalar diffraction by apertures, such as single-slit, double-slit, grating and circular aperture, moving at relativistic speeds with velocities perpendicular to direction of incidence. also studied a single-slit oscillatory shutter. Our study would be significant in probing transverse Doppler effect on intensity...
