In this paper, the quadratic transportation cost inequality for SDEs with Dini continuous drift and W 1 -transportation singular coefficients are established via stability of Wasserstein distance relative entropy measures under homeomorphism induced by Zvonkin’s transformation.

The oxidation mechanism of toluene on the surface heat-treated CeO2 nanoparticles was investigated using diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). When introduced to surface, either chemisorbs an oxygen bound a single cerium atom creating monobound (m) benzyloxy or two neighboring atoms forming bridged (b) benzyloxy. From DRIFTS analysis, benzoate production is direc...

We study a class of nonlocal-diffusion equations with drifts, and derive a priori Φ-Hölder estimate for the solutions by using a purely probabilistic argument, where Φ is an intrinsic scaling function for the equation.

eal world industrial and environmental processes are prone to non-stationary phenomena induced by ageing effects, drifts, soft or hard faults inducing a change over time of the probability density function of acquired measurements [1]. As a consequence, classification systems built over these processes cannot be granted to work properly since the stationarity hypothesis assumed during the param...

Stratospheric temperature series derived from the Advanced Microwave Sounding Unit (AMSU) on board successive NOAA satellites reveal, during periods of overlap, some bias and drifts. Part of the reason for these discrepancies could be atmospheric tides as the orbits of these satellites drifted, inducing large changes in the actual times of measurement. NOAA 15 and 16, which exhibit a long perio...

Monthly shallow water-table depths can be predicted from climate forcings on a large scale by the combination of a transfer-function noise (TFN) model with a parameter regionalization scheme. To investigate the sensitivity of regionalized transfer-function noise (RTFN) models, simulations with different input series and parameter regionalization methods, combined with topographic external drift...

Plant electrical signals often contains low frequency drifts with or without the application of external stimuli. Quantification of the randomness in plant signals in a stimulus-specific way is hindered because the knowledge of vital frequency information in the actual biological response is not known yet. Here we design an optimum Infinite Impulse Response (IIR) filter which removes the low fr...

New mechanism that accounts for position sensitivity of saccades evoked in response to stimulation of superior colliculus. J. Neurophysiol. 80: 3373-3379, 1998. Electrical stimulation of the feline superior colliculus (SC) is known to evoke saccades whose size depends on the site stimulated (the "characteristic vector" of evoked saccades) and the initial position of the eyes. Similar stimuli we...

Recent results in retinal research have shown that ganglion receptive fields cover the mammalian retina in a mosaic arrangement with very small overlap. Classical biology inspired models of the retina performing image processing operations such as edge-detection, in contrast, by using convolution of a filter and the image, map overlapping input image regions to output signals. Without such an o...

The purpose for wireless sensor networks is to deploy low cost sensors with sufficient computing and communication capabilities to support networked sensing applications. Even when the sensors are properly calibrated at the time of their deployment, they develop drift in their readings leading to biased sensor measurements. Noting that a physical phenomenon in a certain area follows some spatio...
