Spatial Smoothing for Diffusion Tensor Imaging with low Signal to Noise Ratios [PDF]
Though low signal to noise ratio (SNR) experiments in DTI give key information about tracking and anisotropy, e.g. by measurements with very small voxel sizes, due to the complicated impact of thermal noise such experiments are up to now seldom analysed.

How to Use White Noise Analysis to Make Feynman Integrals Mathematically Rigorous
In this chapter we summarize applications of White Noise Analysis within the framework of Feynman Path Integrals. With more than 30 years of intensive study this field can be seen as one of the most important applications.

Intelligent Sensors in Software: The Use of Parametric Models for Phase Noise Analysis
Intelligent senors have attracted particular attention in the recent past. This paper argues that an “intelligent sensor” should be able to perform on-board signal processing within the sensor’s software in order to produce the optimal signal output.

Deformation Quantization by Moyal Star-Product and Stratonovich Chaos
We make a deformation quantization by Moyal star-product on a space of functions endowed with the normalized Wick product and where Stratonovich chaos are well defined.

Matched subspace detection with hypothesis dependent noise power [PDF]
We consider the problem of detecting a subspace signal in white Gaussian noise when the noise power may be different under the null hypothesis—where it is assumed to be known—and the alternative hypothesis.

Force feedback linearization for higher-order electromechanical sigma-delta modulators.
A higher-order electromechanical sigma–delta modulator can greatly improve the signal-to-noise ratio compared with a second-order loop that only uses the sensing element as a loop filter.

Interpreting the effects of DNA polymerase variants at the structural level
Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

Longtime asymptotics of the two-dimensional parabolic Anderson model with white-noise potential [PDF]
We consider the parabolic Anderson model (PAM) in ℝ ² with a Gaussian (space) white-noise potential. We prove that the almost-sure large-time asymptotic behaviour of the total mass at time t is given asymptotically by Χ t log t, with the deterministic ...

In this paper, we present an application of the renormalization group method developed by Chen, Goldenfeld and Oono for a stochastic differential equation in a space of Hilbert space-valued generalized random variables with multiplicative noise.

Noise Analysis and Modeling in Visible Light Communication Using Allan Variance
Visible Light Communication (VLC) is a rising communication technology which uses Light-Emitting Diode (LED) luminaries for high-speed data transferring; however, the optical signal is usually degraded by the noise in the practical VLC system.
