Half-linear discrete oscillation theory

Electronic Journal of Qualitative Theory of Differential Equations, 2000
Oscillatory properties of the second order half-linear difference equation $$\Delta(r_k|\Delta y_k|^{\alpha-2}\Delta y_k)+p_k|y_{k+1}|^{\alpha-2}y_{k+1}=0,$$ where $\alpha>1$, are investigated.

de Haas-van Alphen Effect in the Two-Dimensional and the Quasi-Two-Dimensional Systems

, 2001
We study the de Haas-van Alphen (dHvA) oscillation in two-dimensional and quasi-two-dimensional systems. We give a general formula of the dHvA oscillation in two-dimensional multi-band systems.

Generalized Chaplygin gas model: constraints from Hubble parameter versus Redshift Data [PDF]

, 2006
We examine observational constraints on the generalized Chaplygin gas (GCG) model for dark energy from the 9 Hubble parameter data points, the 115 SNLS Sne Ia data and the size of baryonic acoustic oscillation peak at redshift, $z=0.35$.

Oscillatory criteria via linearization of half-linear second order delay differential equations [PDF]

Opuscula Mathematica, 2020
In the paper, we study oscillation of the half-linear second order delay differential equations of the form \[\left(r(t)(y'(t))^{\alpha}\right)'+p(t)y^{\alpha}(\tau(t))=0.\] We introduce new monotonic properties of its nonoscillatory solutions and use ...

Perturbation Theory of Neutrino Oscillation with Nonstandard Neutrino Interactions

, 2009
We discuss various physics aspects of neutrino oscillation with non-standard interactions (NSI). We formulate a perturbative framework by taking \Delta m^2_{21} / \Delta m^2_{31}, s_{13}, and the NSI elements \epsilon_{\alpha \beta} (\alpha, \beta = e ...

Oscillatory behavior of solutions of certain fractional difference equations

Advances in Difference Equations, 2018
In this paper, we consider the oscillation behavior of solutions of the following fractional difference equation: Δ(c(t)Δ(a(t)Δ(r(t)Δαx(t))))+q(t)G(t)=0, $$ \Delta \bigl( c ( t ) \Delta \bigl( a ( t ) \Delta \bigl( r ( t ) \Delta^{\alpha }x ( t ) \bigr) \

Search for CP Violation at a Neutrino Factory in a Four-Neutrino Model [PDF]

, 1999
The CP violation effects in long baseline neutrino oscillations are studied in the framework of a four-neutrino model (three active neutrinos and one sterile neutrino).

The role of alpha oscillations in resisting distraction

Trends in Cognitive Sciences
The role of alpha oscillations (8-13 Hz) in suppressing distractors is extensively debated. One debate concerns whether alpha oscillations suppress anticipated visual distractors through increased power. Whereas some studies suggest that alpha oscillations support distractor suppression, others do not.

Resting-State Alpha-Band Oscillations in Migraine

Perception, 2018
Migraine groups show differences in motion perception compared with controls, when tested in between migraine attacks (interictally). This is thought to be due to an increased susceptibility to stimulus degradation (multiplicative internal noise). Fluctuations in alpha-band oscillations are thought to regulate visual perception, and so differences ...
