Asymptotical expansions in the Kubilius theorem of large deviations

open access: yesLietuvos Matematikos Rinkinys, 2005
In the present paper, a local theorem of large deviations for arithmetic functions defined in Knopfmacher’s semigroup is obtained.

Refuge distributions and landscape connectivity affect host-parasitoid dynamics: Motivations for biological control in agroecosystems

open access: yesPLoS ONE, 2022
Species distributions are affected by landscape structure at different spatial scales. Here we study how the interplay between dispersal at different spatial scales and landscape connectivity and composition affect local species dynamics.

Spectral Energy Distributions for 258 Local Volume Galaxies

open access: yesThe Astronomical Journal, 2023
We present model spectral energy distribution (SED) fits to ultraviolet/optical/infrared observations for the 258 nearby galaxies in the Local Volume Legacy survey, a sample dominated by lower-luminosity dwarf irregular systems.

Tales of Tails

open access: yesEntropy, 2023
Typical human-scaled considerations of thermodynamic states depend primarily on the core of associated speed or other relevant distributions, because the wings of those distributions are so improbable that they cannot contribute significantly to averages.

Local Dependence for Bivariate Weibull Distributions Created by Archimedean Copula

open access: yesمجلة بغداد للعلوم, 2021
In multivariate survival analysis, estimating the multivariate distribution functions and then measuring the association between survival times are of great interest.

Local distributions of multiplicative functions

open access: yesLietuvos Matematikos Rinkinys, 1999
In the present paper the local distribution laws of values of multiplicative arithmetic functions g : G → R defined on arithmetical semigroups G and belonging to the class M(G) is considered.

Rule-Based EEG Classifier Utilizing Local Entropy of Time–Frequency Distributions

open access: yesMathematics, 2021
Electroencephalogram (EEG) signals are known to contain signatures of stimuli that induce brain activities. However, detecting these signatures to classify captured EEG waveforms is one of the most challenging tasks of EEG analysis. This paper proposes a

Spatial distributions of red blood cells significantly alter local haemodynamics. [PDF]

open access: yesPLoS ONE, 2014
Although bulk changes in red blood cell concentration between vessels have been well characterised, local distributions are generally overlooked. Red blood cells aggregate, deform and migrate within vessels, forming heterogeneous distributions which have

Local Limit Theorem for the Multiple Power Series Distributions

open access: yesMathematics, 2020
We study the behavior of multiple power series distributions at the boundary points of their existence. In previous papers, the necessary and sufficient conditions for the integral limit theorem were obtained.
