Cím: Passive tracer advection in the equatorial Pacific region: statistics, correlations and a model of fractional Brownian motion
Szerző: ; ; ;
Dátum: 2022

Evaluating passive tracer advection is a common tool to study flow structures, particularly Lagrangian trajectories ranging from molecular scales up to the atmosphere and oceans. Here we report on numerical experiments in ...
Cím: How the morning-afternoon cloudiness asymmetry affects the energy-maximizing azimuth direction of fixed-tilt monofacial solar panels

In the Northern Hemisphere, south is the conventional azimuth direction of fixed-tilt monofacial solar panels, because this orientation may maximize the received light energy. How does the morning-afternoon cloudiness ...
Cím: Combinatorial Aspects of Poly-Bernoulli Polynomials and Poly-Euler Numbers
Szerző: ;
Dátum: 2022

(2022)
In this article, we introduce combinatorial models for poly-Bernoulli polynomials and poly-Euler numbers of both kinds. As their applications,we provide combinatorial proofs of some identities involving poly-Bernoullipolynomials.

Due to the Chernobyl nuclear power plant accident, contaminated air masses, containing 137Cs, were widely propagated across all of Europe. Cesium-137 is easily adsorbed on aerosol particles as it returns to the ...
Cím: Rapid Expansion of an Aquatic Invasive Species (Ais) in Central-European Surface Waters: A Case Study of Achnanthidium Delmontii

(Elsevier B.V., 2022)
In this work the rapid expansion of a small-celled (<15 µm) monoraphid aquatic invasive species (AIS) along the Central European lotic systems is reported, using the integrated dataset of two large-scale monitoring programs, ...
Cím: Distribution of Spiking and Bursting in Rulkov’s Neuron Model

(Springer Science and Business Media Deutschland GmbH, 2022)
Large-scale brain simulations require the investigation of large networks of realistic neuron models, usually represented by sets of differential equations. Here we report a detailed fine-scale study of the dynamical ...
Cím: A Bijection for the Boolean Numbers of Ferrers Graphs

(Springer Japan, 2022)
In this note we prove a new characterization of the derangement sets of Ferrers graphs and present a bijection between the derangement sets and Fλ-Callan sequences. In particular, this connection reveals that the boolean ...
Cím: Poly-Cauchy numbers of the second kind - the combinatorics behind
Szerző: ;
Dátum: 2022

(2022)
We introduce poly-Cauchy permutations of the second kind that are enumerated by the polyCauchy numbers of the second kind. We provide combinatorial proofs for several identities involving polyCauchy numbers of the second ...
Cím: Metabarcoding as an effective complement of microscopic studies in revealing the composition of the diatom community – a case study of an oxbow lake of Tisza River (Hungary) with the description of a new Mayamaea species

(Pensoft, 2022)
Diatoms are valuable bioindicators and their traditional classification and identification are mainly based on the morphological characteristics of their frustules. However, in recent years, DNA-based methods have been ...
