Helianthus tuberosus at home and away: Stronger ecological impacts in invaded than in native range are not explained by arbuscular mycorrhizal colonization

Robert W. Pal Rita Filep Bradley J. Cook David U. Nagy Katalin Nagy Attila Lengyel Ádám Imri Klára Czakó-Vér Ágnes Farkas

Publication Name: Preslia

Publication Date: 2021-01-01

Volume: 93

Issue: 4

Page Range: 363-376

Description:

The impact of invasive plants on vegetation can vary greatly depending on the characteristics of the invaders and community invasibility. As to the factors that influence a plant's ability to invade, recent studies suggest that arbuscular mycorrhizal fungi (AMF) may be important regulators in plant invasions. To better understand the interactions of Helianthus tuberosus with co-occurring species in its native NorthAmerican and invaded European ranges,we carried out plot-based field surveys to determine whether the cover of H. tuberosus, its stem number and height, bare ground cover and amount of litter differ between ranges and how they interact with numbers of species in the plant community. To provide information aboutAMFcolonization of H. tuberosus,we evaluatedAMFcolonization in both ranges and tested the difference between continents, the effect of cover of H. tuberosus and their interaction with AMF. In the invaded range in Europe, H. tuberosus plants grew taller, had a greater stem density and there were fewer species in the invaded plant communities than in its native range in North America. In contrast, the cover of H. tuberosus and litter cover did not differ between the two continents. Plants of H. tuberosus were colonized by AMF in both ranges, but we found no statistical support for the potential effects of continent, the cover of H. tuberosus and their interaction with AMF. Overall, our study revealed that H. tuberosus exerts a negative impact on co-occurring species in the invaded European range, but not in North America where the species is native. To our knowledge, this is the first evaluation of AMF colonization of H. tuberosus at home and away and the results do not support either the degraded or enhanced mutualism hypotheses.

Publication Name: Foods

Publication Date: 2025-03-01

Volume: 14

Issue: 5

Page Range: Unknown

Description:

Food waste poses a substantial global challenge, with intricate environmental, economic, and ethical ramifications. This study examines household food waste behaviors, emphasizing the interplay of personal responsibility, awareness of consequences, personal norms, and systemic barriers. Employing a thematic analysis of in-depth interviews with 60 households across Hungary’s Central and Western Transdanubian regions, this research explores factors influencing waste-reduction strategies across the pre-, mid-, and post-consumption phases. The thematic analysis of the interview data yielded key themes, including ascription of responsibility (AR), awareness of consequences (AC), personal norms (PN), demographic characteristics (DC), behavioral intentions (FWBI), and barriers (B). Participants identified barriers to waste reduction, such as impulse buying, poor storage practices, and limited knowledge of food rescue initiatives. Incorporating these barriers as a core variable deepens the understanding of systemic challenges, while stage-specific analysis illuminates the evolution of waste-reduction behaviors. These insights will inform targeted interventions, such as community programs, educational campaigns, and technology-driven solutions, including food rescue apps, to foster sustainable consumption. This study’s integration of behavioral theories with actionable strategies provides valuable guidance for policymakers and stakeholders seeking to reduce household food waste on a global scale.

Proposal of a graph-based motion planner architecture

Áron Ballagi Csaba Hajdu

Publication Name: 11th IEEE International Conference on Cognitive Infocommunications Coginfocom 2020 Proceedings

Publication Date: 2020-09-23

Volume: Unknown

Issue: Unknown

Page Range: 393-398

Description:

Motion planning is a critical task in robots and autonomous vehicles. This task is typically complex in computation and structure. Current frameworks are difficult to extend and supervise. This article presents a new architectural proposal of motion planning software, which can be used by mobile robots and autonomous vehicles. Defining aspects have been inspired by the foundations of Cognitive Infocommunications (CogInfoCom) to construct a highly interactive system aiming intuitive human-computer collaboration. The structure is based on a graph-based approach which is suitable in a distributed setting. This formalization provides a graphical behavior description, an intuitive way for human actors to interact with the system. The behavior of each acting component is based on a hybrid-system formalism which can further serve as a basis to model human behavior.

Quantifying Geotechnical Uncertainty in Ground Motion Predictions: Bayesian Generalized Linear Model Framework

Description:

Accurate prediction of peak ground intensity measures is inevitably influenced by geotechnical variability. Variations in soil properties, subsurface conditions, and seismic inputs introduce complexities that challenge the reliability of predictions. This study introduces a Bayesian generalized linear model (GLM) to probabilistically predict peak ground acceleration (PGA) while accounting for uncertainties associated with geotechnical variability. Latin hypercube sampling (LHS) was employed to generate synthetic datasets of key geotechnical parameters, including plasticity index, shear wave velocity, soil thickness, input motion intensity, and unit weight of soil for hypothetical sites. Subsequently, a series of one-dimensional equivalent linear (1D-EQL) seismic site response analyses were performed, and PGA value at ground surface level were recorded for each analysis. The Bayesian GLM was then developed using these comprehensive datasets to probabilistically predict PGA. The performance and reliability of the developed model were evaluated on a separate test dataset. To benchmark its performance, a Bayesian neural network (BNN) was also developed and compared. In addition, a Shiny-based graphical user interface (GUI), named Bayes-PGA-predictor, was implemented to facilitate practical application. The findings demonstrate that the Bayesian GLM offers a robust and interpretable approach to predicting PGA while effectively quantifying uncertainty associated with geotechnical variability.

MULTILATERAL EVALUATION OF ENERGY TECHNOLOGIES - PROPOSAL OF AN INTEGRATED MODEL

András Torma Géza Köteles

Publication Name: Iet Conference Proceedings

Publication Date: 2024-01-01

Volume: 2024

Issue: 8

Page Range: 76-81

Description:

There are many different solution available to meet a given energy demand. These solutions may differ significantly not only in their technical and economic characteristics but also in their effects on the environment. The purpose of this article is to present principles, considerations, and methods for a complex assessment of the production, conversion, transportation, storage, and end-use of various types of energy. The authors present seven distinct approaches, principles, and methodologies that are commonly employed to comprehend the consequences of various energy utilization solutions. The characteristics of each model and the range of information provided by each solution are presented through concrete examples. The applicability of different methods and approaches is also analysed comparatively. These methods have not yet been translated so far into a coherent, integrated model by either engineering practice or academia, although an accurate understanding of the impacts on the sustainability and energy trilemma necessitates applying as complex analytical solutions as possible. The objective of this article is to collate, evaluate, and harmonise a range of widely used energy usage evaluation models. The aim is to propose a coherent, integrated approach to facilitate a more comprehensive understanding of the environmental, technical, and financial implications of different energy utilisation approaches.

From the order of things to the rule of the masses or historical lessons on the relationship between the State and the extensions of rights

Gergely Deli

Publication Name: Rechtskultur

Publication Date: 2024-01-01

Volume: Unknown

Issue: Unknown

Page Range: 97-112

Description:

It is a common belief that democratic development involves the extension of rights. Often, a desired extension of rights is one of the main social drivers of democratic transformation. In this study, within the framework of a legal history investigation, I am looking for the answer to the question of whether all extensions of rights are necessarily democratic, and how to distinguish between different extensions of rights and to judge the social usefulness of each extension of rights more accurately? I distinguish two sub-cases of the extension of rights, the subjective and objective versions with different normative consequences. I conclude that it is worth subjecting certain extensions of rights to legal, constitutional and political-social considerations. The extension of rights is not ab ovo or absolutely good, its judgment depends on the given circumstances.
