Thomson scattering of plasma turbulence on PSI-2

open access: yesNuclear Materials and Energy, 2017
The turbulent transport in the edge of fusion reactors can be conveniently simulated by linear plasma devices with long duty cycles. At high input power steady state plasma discharges at PSI-2 exhibit intermittent fluctuations similar to the edge of ...

On conditions of oscillations and multi-homogeneity [PDF]

open access: yesMathematics of Control, Signals, and Systems, 2015
The main idea of this paper is to reduce the analysis of the asymptotic behavior (stability, instability, presence of oscillations related to chaos) of a nonlinear dynamical system defined by a time-invariant ordinary differential equation \[ \dot x = f(x), \qquad x\in\mathbb R^n \] to the analysis of a simpler approximating system \[ \dot x = f_0(x). \

Controllable conditional quantum oscillations and synchronization in superconducting flux qubits

open access: yes, 2010
Conditional quantum oscillations are investigated for quantum gate operations in superconducting flux qubits. We present an effective Hamiltonian which describes a conditional quantum oscillation in two-qubit systems.

Conditional Oscillation of Half-Linear Differential Equations with Coefficients Having Mean Values

open access: yesAbstract and Applied Analysis, 2014
We prove that the existence of the mean values of coefficients is sufficient for second-order half-linear Euler-type differential equations to be conditionally oscillatory.

Spatiotemporal Analysis of Extreme Temperature Change on the Tibetan Plateau Based On Quantile Regression

open access: yesEarth and Space Science, 2022
Temperature extremes have been extensively observed on the Tibetan Plateau (TP), of which the dynamics were mostly monitored by traditional trend analysis based on linear regression.

Energy reconstruction in quasielastic scattering in the MiniBooNE and T2K experiments

open access: yes, 2012
Neutrino oscillation probabilities, which are being measured in long-baseline experiments, depend on neutrino energy. The energy in a neutrino beam, however, is broadly smeared so that the neutrino energy in a particular event is not directly known, but ...

Photonic polarization gears for ultra-sensitive angular measurements [PDF]

open access: yes, 2013
Quantum metrology bears a great promise in enhancing measurement precision, but is unlikely to become practical in the near future. Its concepts can nevertheless inspire classical or hybrid methods of immediate value.

Conditional control of quantum beats in a cavity QED system

open access: yes, 2011
We probe a ground-state superposition that produces a quantum beat in the intensity correlation of a two-mode cavity QED system. We mix drive with scattered light from an atomic beam traversing the cavity, and effectively measure the interference between

Conditional mutual information maps as descriptors of net connectivity levels in the brain

open access: yesFrontiers in Neuroinformatics, 2010
There is a growing interest in finding ways to summarise the local connectivity properties of the brain through single brain maps. Here we propose a method based on the conditional Mutual Information in the frequency domain.

Oscillations of empirical distribution functions under dependence

open access: yes, 2006
We obtain an almost sure bound for oscillation rates of empirical distribution functions for stationary causal processes. For short-range dependent processes, the oscillation rate is shown to be optimal in the sense that it is as sharp as the one ...
