András Lajos Nagy Réka Kolláti Attila Ősi

Publication Name: Palaeobiodiversity and Palaeoenvironments

Publication Date: 2025-06-01

Volume: 105

Issue: 2

Page Range: 499-515

Description:

Theropod teeth have long been known from the Upper Cretaceous of Europe, but the 20 million years long interval spanning the Cenomanian to the Campanian has remained underrepresented in the fossil record and understudied. Recent discoveries from the Turonian and Coniacian of Austria and the Santonian of Hungary fill this gap to some extent. Here we report on a study of 2D morphometry and dental wear of Turonian–Maastrichtian theropod teeth from Central Europe aimed at shedding further light on the phyletic and adaptive diversity of Late Cretaceous theropods in the archipelago of Europe. Our results suggest that the taxa Paraves indet. and Paronychodon were present in the region from the Turonian to the Maastrichtian, while medium-sized tetanuran forms are known only until the early Campanian. The record of some groups, such as troodontid or bird-like forms, is more sporadic and known only from a few sites. Dental wear study indicates that theropod teeth rarely show severe wear exposing dentin, though spalled surfaces are commonly seen on tetanuran teeth. Dental microwear feature and texture analysis of the worn enamel surfaces show a dominance of scratches (82–100%), with somewhat higher complexity in some of the non-serrated forms. The largest tetanuran teeth differ in terms of scratch length, pit size and anizotropy from the small, serrated Paraves indet. 1 teeth, but overlap with those of the extant carnivore-scavenger Varanus komodoensis suggesting large tetanurans resembled V. komodoensis in feeding on large vertebrates.

Description:

Inefficient material tracking continues to be a major challenge in sustainable construction, often leading to unnecessary waste, budget overruns, and project delays. While many digital tools have been introduced in recent years, there is still a lack of practical, field-tested frameworks that combine these technologies with clear, structured procedures, especially in resource-constrained environments. This study introduces a Standard Operating Procedure (SOP) framework designed to improve materials tracking systems (MTSs) by integrating QR codes, GPS tracking, and cloud-based dashboards. Together, these tools support more accurate planning, smoother coordination, and real-time monitoring from the early design stages to on-site implementation. A mixed-methods approach was used, combining surveys with construction professionals and focus group discussions with engineers, IT specialists, and logistics staff. The findings highlight procurement and implementation as the phases most prone to inefficiencies, particularly around material receiving, quality checks, and on-site placement. The validated SOP framework shows strong potential to improve tracking accuracy, reduce material waste, and streamline construction workflows. It offers a flexible, easy-to-use system for integrating sustainability into everyday project practices. Looking ahead, this study also points to future opportunities for applying AI-based tools—such as predictive tracking and automated quality checks—to further improve decision-making and resource efficiency in construction projects.

Page Range: Unknown

Description:

Parkinson’s disease (PD) is a progressive movement disorder with no cure. In this randomized controlled study, 100 patients with PD were assigned to four intervention groups (Exergame, Cycling, Agility, and Robot) for 14 weeks. This study evaluates the effectiveness of high-intensity therapy in a randomized clinical trial. Exergaming, cycling, agility, and robot therapies improved motor function, postural stability, and cardiovascular health. Heart rate monitoring and Borg Scale ratings confirmed the safety and adaptability of high-intensity training, with patients sustaining moderate-to-high exertion without adverse effects. Significant improvements were observed in gait speed (+0.30–0.50 m/s), Functional Independence Measure (FIM) (+25–30 points), and Berg Balance Scale scores. Integrating high-intensity, functional movement-based therapies into PD rehabilitation may offer superior motor, gait, and cardiovascular benefits compared to conventional methods.

How Weed Flora Evolves in Cereal Fields in Relation to the Agricultural Environment and Farming Practices in Different Sub-Regions of Eastern Hungary

Zita Dorner Mihály Zalai János György NAGY Erzsébet Tóth

Publication Name: Agronomy

Publication Date: 2025-05-01

Volume: 15

Issue: 5

Page Range: Unknown

Description:

This study explores the relationship between abiotic factors, farming practices, and weed growth in winter wheat fields in Eastern Hungary. It examines the order of weed dominance and the influence of soil, environmental, and agricultural variables on weed composition and diversity before herbicide application. The research was conducted across four sub-regions in the Great Hungarian Plain, each with distinct soil, hydrological, and geographical conditions. Between 2018 and 2021, 103 fields were surveyed and weed species cover was recorded using EPPO-based identification and quadrat sampling. Soil properties, environmental conditions, and farming practices were documented through soil analysis, geographical data, and farmer interviews. Statistical analyses were preformed including ANCOVA, redundancy analysis, and Shannon diversity index calculations. The results show that common weed species include Veronica hederifolia, Stellaria media, and Apera spica-venti, with winter annuals dominating. Soil compaction and salinity affected weed diversity, while increased copper and zinc concentrations had minor effects on weed coverage. Farming practices, particularly tillage systems and fertilizer use, had a significant effect on species richness and diversity. Different regional and annual weed distributions were observed, with correlation between certain tillage systems and specific weed species. The results emphasize the need for climate-conscious farming practices, and we recommend prioritising shallow cultivation and deep loosening over ploughing in order to manage weed populations effectively. These insights contribute to sustainable weed management strategies in cereal production.

Page Range: Unknown

Description:

The cushioning performance of insole has always been a critical consideration in its design. While the development of intelligent methods and the emergence of additive manufacturing (AM) technology have enhanced design freedom and convenience, a standardized approach to guide designers in selecting optimal materials and structures for specific scenarios is still lacking. This study aims to propose a controllable parameterized lattice cushioning insole (PLI) by integrating finite element (FE) and machine learning (ML) methods. The insole performance can be adjusted by modifying the structural parameters (a, b) and the internal strut thickness (t). The findings indicate that PLI, under the optimal parameter combination (a = 2.54, b = 3.56, t = 3.15), can reduce plantar pressure by up to 44.45 %, which may be achieved by increasing the contact between the footwear and the foot. The data-driven PLI optimization design method proposed in this study significantly enhances the cushioning performance of insole structures, simplifies the optimization process for selecting insole structures or materials, and provides a systematic and efficient solution for insole design. Although the initial preparation of material data is time-intensive, the trained model eliminates the need for repeated laboratory gait analysis or plantar pressure measurements, offering a foundational reference for clinical applications in insole structure design.

Szabolcs Fischer János Hollósi Mykola Sysyn Gabor Kovacs Dmytro Kurhan Viktor Nagy

Publication Name: Computers

Publication Date: 2025-05-01

Volume: 14

Issue: 5

Page Range: Unknown

Description:

Driver distraction can have severe safety consequences, particularly in public transportation. This paper presents a novel approach for detecting bus driver actions, such as mobile phone usage and interactions with passengers, using Kolmogorov–Arnold networks (KANs). The adversarial FGSM attack method was applied to assess the robustness of KANs in extreme driving conditions, like adverse weather, high-traffic situations, and bad visibility conditions. In this research, a custom dataset was used in collaboration with a partner company in the field of public transportation. This allows the efficiency of Kolmogorov–Arnold network solutions to be verified using real data. The results suggest that KANs can enhance driver distraction detection under challenging conditions, with improved resilience against adversarial attacks, particularly in low-complexity networks.

Issue: Unknown

Page Range: Unknown

Description:

Increased global plastic consumption and production boosted the amount of end-of-life (EoL) plastic. Also, 90 % of plastic EoL is either landfilled or incinerated. These unsustainable EoL pathways impact the environment and human health and waste valuable materials. Thus, improvements to the existing recycling infrastructure for sustainable plastic management are needed to enhance plastic circularity. Therefore, this contribution addresses optimizing cost-effective pathways for plastic recycling within the supply chain. The research uses mathematical optimization and the P-graph theoretical framework to calculate recycling costs, encompassing both capital expenditure and operational expenditure for various pathways of plastic recycling. The proposed methodology is applied through a detailed case study in Miskolc, Hungary, revealing estimated recycling costs ranging from 54.9 to 59.28 EUR/ton. This finding provides crucial insights into the economic implications of diverse recycling methods. Also, the study highlights the P-graph model's untapped potential as a resource for decision-makers in plastic recycling, particularly the enumeration of options for further consideration. The work's utility and novelty lie in the model's capability to design cost-effective pathways, offering a tangible contribution to the plastic recycling supply chain. Finally, this contribution offers economic solutions needed to ensure cost-effective sustainable plastic management solutions.

Adjacent-Channel Compatibility Analysis of International Mobile Telecommunications Downlink and Digital Terrestrial Television Broadcasting Reception in the 470–694 MHz Frequency Band Using Monte Carlo Simulation

Péter Vári Hussein Taha Szilvia Nagy

Publication Name: Electronics Switzerland

Publication Date: 2024-02-01

Volume: 13

Issue: 3

Page Range: Unknown

Description:

This paper delves into the imperative need for coexistence and compatibility in the 470–694 MHz frequency band, as mandated by the World Radiocommunication Conference 2015 (WRC-15) and the WRC-23. It focuses on challenges in the coexistence of Digital Terrestrial Television Broadcasting (DTTB) and International Mobile Telecommunications-2020 (IMT-2020) services in downlink-only mode, particularly in adjacent-channel scenarios. Using Monte Carlo simulations, the study evaluates the probability of interference from IMT base stations with DTTB reception. The analysis thoroughly investigates the impact of the IMT transmitter’s Adjacent Channel Leakage Ratio (ACLR) and the DTTB receiver’s Adjacent-Channel Selectivity (ACS) on the probability of interference. The results demonstrate a significant degradation in the DTTB reception probability at the edge of coverage based on standard assumptions. To address these challenges, this paper provides recommendations for mitigating interference. These include defining enhanced ACLR regulations for IMT base stations, implementing antenna discriminations, providing specialized filters, and establishing national coordination procedures. The research provides valuable insights for informed decision making in spectrum management within the 470–694 MHz band, aiming to facilitate the coexistence of DTTB and IMT-2020 services, in line with international regulations and best practices.
