Can the average drift of an ensemble of charged particles in Earth's plasma sheet still be described by adiabatic theory even if many particles in the ensemble execute non adiabatic motion? This is part of a broader spectrum of questions which asks if chaotic microscopic processes can be parameterized as macroscopic ones when ensemble averaged. Through a comparison of numerical test particle si...

Modern analytical laboratories require tools to assess uncertainties at every step of the analytical process. Borate fusion combined with X-Ray fluorescence has often been demonstrated to be essential for the determination of major elements in cements, ores and a large number of other matrixes. However, drift and bias contributions from the fusion technique, burner position, fluxer to fluxer, m...

This paper describes a class of rater effects that depict rater-by-time interactions. We refer to this class of rater effects as DRIFT differential rater functioning over time. This article describes several types of DRIFT (primacy/recency, differential centrality/extremism, and practice/fatigue) and Rasch measurement procedures designed to identify these types of DRIFT in rating data. These pr...

This paper is concerned with the linear ODE in the form y(t) = λρ(t)y(t)+b(t), λ < 0 and which represents a simplified model of storage of the carbon in the soil. In the first part, we show that, for a periodic function ρ(t), a linear drift in the coefficient b(t) involves a linear drift for the solution of this ODE. In the second part, we give sufficient conditions on the coefficients to ensur...

This work proposes a new, online algorithm for estimating the local scale correction to apply to the output of a monocular SLAM system and obtain an as faithful as possible metric reconstruction of the 3D map and of the camera trajectory. Within a Bayesian framework, it integrates observations from a deep-learning based generic object detector and a prior on the evolution of the scale drift. Fo...

We propose a model for diffusion-limited annihilation of two species, A+ B → A or B, where the motion of the particles is subject to a drift. For equal initial concentrations of the two species, the density follows a power-law decay for large times. However, the decay exponent varies continuously as a function of the probability of which particle, the hopping one or the target, survives in the ...

We study a d-dimensional reflected fractional Brownian motion (RFBM) process on the positive orthant S = R+, with drift r0 ∈ R and Hurst parameter H ∈ ( 1 2 , 1). Under a natural stability condition on the drift vector r0 and reflection directions, we establish a geometric drift towards a compact set for the 1-skeleton chain Z̆ of the RFBM process Z; that is, there exist β, b ∈ (0,∞) and a compa...

The pelagic larvae of many marine organisms can potentially disperse across hundreds of kilometers, but whether oceanographic or behavioral mechanisms can constrain dispersal over periods sufficient for the evolution of genetic differentiation remains unclear. Here, we concurrently examine larval duration and genetic population differentiation in a cleaner goby, Elacatinus evelynae, a member of...

abstract in this research sand drifts potential using sand rose graph software and fryberger velocity classes’ method investigated. thus wind data between 1985 and 2005 from meteorological stations of jask and kerman were analyzed to examine sand drift potential. sand drift potential amount of kerman station was 412.6 using sand rose graph and 401.09 using fryberger,s method. sand drift potenti...
