Cím: Set partitions and non-crossing partitions with l-neighbors and l-isolated elements
Szerző: ; ;
Dátum: 2022

(2022)
In this paper we introduce the notion of an -neighbor element of set partitions, that is, an element a in a block that contains +1 consecutive elements, among which is a . Elements that are not -neighbors are called -isolated ...
Cím: Markov chain analysis of the probability of days in the heat wave period

The impact of global climate change is also felt in Hungary. An undesirable effect of climate change (associated with rising temperatures) is mainly the increase in the frequency, intensity, and length of summer heat waves. ...
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

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 ...
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
Szerző: ; ; ;
Dátum: 2022
Feltöltve: 2022-04-13
(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
Szerző:
Dátum: 2022
Feltöltve: 2022-04-13
(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: Unfair distributions counted by the generalized Stirling numbers
Szerző: ; ;
Dátum: 2022
Feltöltve: 2023-02-17
(2022)
We investigate the generalized Stirling numbers S(n, k; α, β, γ) introduced by Hsu
and Shiue from a combinatorial point of view. We present a combinatorial interpretation in terms of certain restricted distributions of ...
Cím: On Higher Order Generalized Geometric Polynomials with Shifted Parameters
Szerző: ; ;
Dátum: 2022
Feltöltve: 2023-02-20
(2022)
We study a special class of higher order generalized geometric polynomials. Based on our combinatorial interpretation of labeled barred preferential arrangements, we prove several recursions. We also study the polynomials ...
Cím: Assessing the structure and composition of artificial levees along the Lower Tisza River (Hungary)
Szerző: ; ; ; ; ; ; ;
Dátum: 2022

Levees are earth structures constructed along alluvial rivers and are considered to be one of the essential components of flood risk and natural hazard reduction. The preservation of their condition would require orderly ...
Cím: Water resources management and its homeland security aspect in Hungary
Szerző: ; ; ;
Dátum: 2022
Feltöltve: 2023-09-11
(2022)
As a consequence of climate change, extreme weather events will have a profound impact on water resources, environmental security and longterm social compatibility. This is particularly true in the Danube river basin ...
