Cím: Warm Younger Dryas summers and early late glacial spread of temperate deciduous trees in the Pannonian Basin during the last glacial termination (20-9 kyr cal BP)
Szerző: ; ; ; ; ; ; ; ;
Dátum: 2019

This paper focuses on the last glacial termination vegetation and climate reorganization of the Eastern Pannonian Plain via the multi-proxy paleoecological analysis of Kokad mire in Eastern Hungary. Grains size, sediment ...
Cím: Heterogeneity and Anthropogenic Impacts on a Small Lowland Stream

During our work, we investigated the physical and chemical variables of a small surface watercourse to investigate how different anthropogenic effects affect its water quality. Along this small watercourse, there are ...
Cím: Trait-based community assembly of epiphytic diatoms in saline astatic ponds: a test of the stress-dominance hypothesis
Szerző: ; ; ; ; ; ; ; ;

The stress dominance hypothesis (SDH) postulates that strong environmental gradients drive trait convergence in communities over limiting similarity. Previous studies, conducted mostly with terrestrial plant communities, ...
Cím: Unfair distributions counted by the generalized Stirling numbers

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: Weak Ascent Sequences and Related Combinatorial Structures
Szerző: ; ;
Dátum: 2023

In this paper we introduce weak ascent sequences, a class of number sequences that properly contains ascent sequences. We show how these sequences uniquely encode each of the following objects: permutations avoiding a ...
Cím: Mammal Extinction Facilitated Biome Shift and Human Population Change During the Last Glacial Termination in East-Central Europe

"The study of local extinction times, together with the associated environmental and human population changes in the last glacial termination, provides insights into the causes of mega- and microfauna extinctions. In ...
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
Szerző: ; ; ; ; ;
Dátum: 2022

(2022)
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 ...

"In the present study 12 water samples of five sampling sites (Tatabánya, Dandár, Szentendre,Szent Flórián and Ciprián groundwaters) known as nutrient-depleted aquatic environments werestudied using amplicon sequencing ...
Cím: Exogenic Production of Bioactive Filamentous Biopolymer by Monogonant Rotifers
Szerző: ; ; ; ; ; ; ;
Dátum: 2021

(2021)
The chemical ecology of rotifers has been little studied. A yet unknown property is presented within some monogonant rotifers, namely the ability to produce an exogenic filamentous biopolymer, named ‘Rotimer’. This ...
