Mitigation of the Effects of Unknown Sea Clutter Statistics by Using Radial Basis Function Network [PDF]

open access: yesRadioengineering, 2020
In this paper, we investigate feasibility of employing Radial Basis Function (RBF) network into non-coherent detection process, for detection of targets embedded in sea clutter of unknown statistics. We particularly have in mind Croatian part of Adriatic

Lognormal firing rate distribution reveals prominent fluctuation–driven regime in spinal motor networks

open access: yeseLife, 2016
When spinal circuits generate rhythmic movements it is important that the neuronal activity remains within stable bounds to avoid saturation and to preserve responsiveness. Here, we simultaneously record from hundreds of neurons in lumbar spinal circuits

Firm size and economic concentration: An analysis from a lognormal expansion.

open access: yesPLoS ONE, 2021
This paper studies the distribution of the firm size for the Colombian economy showing evidence against the Gibrat's law, which assumes a stable lognormal distribution.

Simple accurate lognormal approximation to lognormal sums

open access: yesElectronics Letters, 2005
A simple accurate lognormal approximation to the sum of independent non-identical lognormal variates is derived by matching the first two moments of the inverse exact sum with those of the inverse lognormal approximation. Sample examples are given to illustrate the excellent agreement between exact and approximate sum statistics.

Random phenotypic variation of yeast (Saccharomyces cerevisiae) single-gene knockouts fits a double pareto-lognormal distribution. [PDF]

open access: yesPLoS ONE, 2012
Distributed robustness is thought to influence the buffering of random phenotypic variation through the scale-free topology of gene regulatory, metabolic, and protein-protein interaction networks.

Description of the Joint Probability of Significant Wave Height and Mean Wave Period

open access: yesJournal of Marine Science and Engineering, 2022
The bivariate probability distribution of significant wave heights and mean wave periods has an indispensable guiding role in the implementation of offshore engineering, which has attracted great attention.

Improving lognormal models for cosmological fields [PDF]

open access: yes, 2016
It is common practice in cosmology to model large-scale structure observables as lognormal random fields, and this approach has been successfully applied in the past to the matter density and weak lensing convergence fields separately. We argue that this

Correlated connectivity and the distribution of firing rates in the neocortex [PDF]

open access: yes, 2008
Two recent experimental observations pose a challenge to many cortical models. First, the activity in the auditory cortex is sparse, and firing rates can be described by a lognormal distribution.

Theoretical approach for uncertainty quantification in probabilistic safety assessment using sum of lognormal random variables

open access: yesNuclear Engineering and Technology, 2022
Probabilistic safety assessment is widely used to quantify the risks of nuclear power plants and their uncertainties. When the lognormal distribution describes the uncertainties of basic events, the uncertainty of the top event in a fault tree is ...
