Coherence resonance in a noise-driven gene network regulated by small RNA

open access: yesTheoretical and Applied Mechanics Letters, 2014
Small RNA has recently drawn more and more attention. In this paper, we concentrate on the influence of noises on gene network regulated by small RNA using chemical Langevin equation.

Robust features for textures in additive noise [PDF]

open access: yes, 1995
The paper describes a method for texture classification in noise by using third-order cumulants as discriminating features. The problem is formulated as a test on K hypotheses and solved by a Maximum Likelihood (ML) criterium applied in the third-order cumulant domain.

Rivers under Additive Noise

open access: yesJournal of Dynamics and Differential Equations
Abstract We consider the deterministic and stochastic versions of a first order non-autonomous differential equation which allows us to discuss the persistence of rivers (“fleuves”) under additive noise.

Asymptotic behavior of non-autonomous fractional p-Laplacian equations driven by additive noise on unbounded domains

open access: yesBulletin of Mathematical Sciences, 2021
This paper deals with the asymptotic behavior of solutions to non-autonomous, fractional, stochastic p-Laplacian equations driven by additive white noise and random terms defined on the unbounded domain ℝN.

BPG-Based Lossy Compression of Three-Channel Noisy Images with Prediction of Optimal Operation Existence and Its Parameters

open access: yesRemote Sensing, 2023
Nowadays, there is a clear trend toward increasing the number of remote-sensing images acquired and their average size. This leads to the need to compress the images for storage, dissemination, and transfer over communication lines where lossy ...

Beautiful and functional : a review of biomimetic design in additive manufacturing [PDF]

open access: yes, 2019
: This review article summarizes the current state-of-the-art for biomimicry in additive manufacturing. Biomimicry is the practice of learning from and emulating nature - which can be increasingly realized in engineering applications due to progress in ...

Statistical monitoring of weak spots for improvement of normalization and ratio estimates in microarrays

open access: yesBMC Bioinformatics, 2004
Background Several aspects of microarray data analysis are dependent on identification of genes expressed at or near the limits of detection. For example, regression-based normalization methods rely on the premise that most genes in compared samples are ...

Representing Microphysical Uncertainty in Convective‐Scale Data Assimilation Using Additive Noise

open access: yesJournal of Advances in Modeling Earth Systems, 2021
For convective clouds and precipitation, model uncertainty in cloud microphysics is considered one of the most significant sources of model error. In this study, samples for model microphysical uncertainty are obtained by calculating the differences ...
