We consider an elliptic and time-inhomogeneous diffusion process with timeperiodic coefficients evolving in a bounded domain of R with a smooth boundary. The process is killed when it hits the boundary of the domain (hard killing) or after an exponential time (soft killing) associated with some bounded rate function. The branching particle interpretation of the non absorbed diffusion again beha...

Trimaximal mixing is the mixing hypothesis with maximal symmetry. In trimaximal mixing there remains a still worrying conflict between the large values of ∆m preferred by the atmospheric fits (possibly supported by the early K2K data) and reactor limits on νe-mixing. However, the latest solar results do seem to point to energy-independent (ie. ‘no-scale’) solar solutions, like the trimaximal so...

Abstract. The changes in vortical and turbulent structure in the near field (X/D < 3.0) of jet mixing flow caused by a lobed nozzle were investigated experimentally in the present study. The techniques of planar laser induced fluorescence and particle image velocimetry were used to accomplish flow visualization and velocity field measurements. The experimental results showed that, compared with...

Exotic explanations are considered for atmospheric neutrino observations. Our analysis includes matter effects and the mixing of all three neutrinos under the simplifying assumption of only one relevant mixing scale. Constraints from accelerator, reactor and solar neutrinos are included. We find that the proposed mixing mechanisms based on violations of Lorentz invariance or on violations of th...

The vortical and turbulent structure changes in the near field (X/D<3.0) of the jet mixing flow caused by a lobed nozzle had been investigated experimentally in the present study. The techniques of planar Laser Induced Fluoresce (LIF) and Particle Image Velocimetry (PIV) were used to accomplish the flow visualization and velocity field measurements. The experimental results showed that, compare...

Effect of scale on the hydrodynamics of gas-solid fluidized beds was investigated in two fluidized beds of 152 mm and 78 mm in diameter.  Air at room temperature was used as the fluidizing gas in the bed of sand particles. The Radioactive Particle Tracking (RPT) technique was employed to obtain the instantaneous positions of the particles at every 20 ms of the experiments. These data were u...

Considering multivariate strongly mixing time series, nonparametric tests for a constant copula with specified or unspecified change point (candidate) are derived; the tests are consistent against general alternatives. A tapered block multiplier technique based on serially dependent multiplier random variables is provided to estimate p-values of the test statistics. Size and power of the tests ...

Let f : [0, 1]× [0, 1]\{1/2} → [0, 1]× [0, 1] be the C∞ endomorphism given by f(x, y) = ( 2x− b2xc, y + c |x− 1/2| − ⌊ y + c |x− 1/2| ⌋) , c ∈ IR We prove that f is topologically mixing and if c > 1/4 then f is mixing with respect to Lebesgue measure. Furthermore we prove that the speed of mixing is exponential. This skew-product can be seen as a toy-model related to Lorenz-like attractors. 200...

Energetic ion bombardment during plasma etching of microelectronics devices is necessary to activate chemical process and define features through the ions’ anisotropic trajectories. These energetic fluxes can also cause damage and mixing of the constituents of crystalline lattices. These properties are likely best modeled using molecular dynamics (MD) simulations. The computational expense of t...
