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 ...

(Elsevier B.V., 2022)
Interdefinability of timelike, lightlike and spacelike relatedness of Minkowski spacetime is investigated in detail in the paper, with the aim of finding the simplest definitions. Based on ideas scattered in the literature, ...
Cím: Combinatorial Aspects of Poly-Bernoulli Polynomials and Poly-Euler Numbers
Szerző: ;
Dátum: 2022
Feltöltve: 2023-03-07
(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.
Cím: Factors Influencing Algal Photobiohydrogen Production In Algal-Bacterial Co-Cultures
Szerző: ; ; ; ; ; ;
Dátum: 2017
Feltöltve: 2023-03-07
(2017)
Algal-bacterial co-cultures represent an alternative way for algal biohydrogen generation. Efficient algal hydrogen production requires anaerobiosis and electrons accessible for the algal FeFe?hydrogenases. A number of ...
Cím: Minimum Entropy Production Effect on a Quantum Scale
Szerző: ;
Dátum: 2021
Feltöltve: 2023-04-20
(2021)
The discovery of quantized electric conductance by the group of van Wees in 1988 was a major breakthrough in physics. A decade later, the group of Schwab has proven the existence of quantized thermal conductance. Advancing ...
Cím: Ornithological and molecular evidence of a reproducing Hyalomma rufipes population under continental climate in Europe

This research introduces a compartmental model designed to address the critical challenge of cost-effective pandemic modeling and analysis. The proposed framework extends the Susceptible, Exposed, Infectious, and Recovered ...
Cím: The effect of time resolution on energy system simulation in case of intermittent energies
Szerző: ; ;
Dátum: 2024
Feltöltve: 2024-01-17
(2024)
The management and integration of intermittent renewable energy sources, such as wind and solar power, require precise capacity planning due to their variable nature. This study investigated the efficacy of using hourly ...
