Imaging spin-inelastic Friedel oscillations emerging from magnetic impurities
, 2012 We consider inelastic scattering of localized magnetic moments coupled with the electrons on the surface. We argue that spin-inelastic transitions of the magnetic impurities generate oscillations at a momentum $k$, corresponding to the inelastic mode, in

Damped transverse oscillations of interacting coronal loops
, 2015 Damped transverse oscillations of magnetic loops are routinely observed in the solar corona. This phenomenon is interpreted as standing kink magnetohydrodynamic waves, which are damped by resonant absorption owing to plasma inhomogeneity across the ...

Treating cancerous cells with viruses: insights from a minimal model for oncolytic virotherapy
Letters in Biomathematics, 2018 In recent years, interest in the capability of virus particles as a treatment for cancer has increased. In this work, we present a mathematical model embodying the interaction between tumour cells and virus particles engineered to infect and destroy ...

Frontiers in Integrative Neuroscience, 2009 A governing assumption about repetitive transcranial magnetic stimulation (rTMS) has been that it interferes with task-related neuronal activity – in effect, by “injecting noise” into the brain – and thereby disrupts behavior ...

Some Unsettled Questions in the Problem of Neutrino Oscillations
, 2002 It is noted that the theory of neutrino oscillations can be constructed only in the framework of the particle physics theory, where is a mass shell conception and then transitions (oscillations) between neutrinos with equal masses are real and between ...

Spurious oscillations in IMPATT oscillators
Electronics Letters, 1975 Incorrect circuit design of cavity-controlled IMPATT oscillators may cause low-frequency instabilities and frequency jumping, which are simply avoidable. A simple technique for identifying the avalanche resonance frequency of packaged IMPATT oscillators is also described.

Synchronization of Oscillators
Proceedings of the IRE, 1947 A theory is presented which predicts the behavior of any self-limiting oscillator in the presence of an injected sinusoidal voltage or current of small but constant magnitude. The internal mechanism responsible for synchronization is not needed, and the theory is thus applicable to any source of alternating current.

Journal of Approximation Theory, 2010 An algebraic polynomial that has all its zeros in a finite interval \([a,b]\) is called oscillating on \([a,b]\). In the present paper the authors prove the following Theorem. Let \(P\) be an oscillating on \([-1,1]\) polynomial of degree \(n\) with symmetric zeros, and let \(P\) attain its maximal absolute value at the endpoints.
