Description:

Behavioural addictions may negatively impact athletic performance and overall health. Little data exist on endurance runners. We conducted a cross-sectional survey study in endurance (≥21.1 km to 42.2 km) and ultra-endurance runners (≥42.2 km), screening for alcohol misuse, substance use (SU), gambling, and exercise addictions (EA) while assessing potential associated risk factors. Statistical analysis included descriptive statistics, the Kruskal–Wallis H-test with post-hoc Dunn´s test, a Multivariable Logistic Regression model, and a CatBoost Classifier, with model interpretability techniques such as Shapley Additive Explanations (SHAP) and Partial Dependence Plots (PDPs). Of 601 runners, 222 were females (37%); their mean age was 42.8±10.1 years; 28.6% screened positive for alcohol, 26.1% for SU, 18.1% for EA, and 8.0% for problematic gambling. SU was more prevalent among female runners (p = 0.02) and half-marathoners (p = 0.007), whereas gambling was more common among men (p = 0.02). Women reported higher EA than men (p < 0.001). Risk factors for alcohol misuse included younger age (25–33 years, p = 0.007), fewer workouts (p = 0.025), and higher income (p < 0.001). SU risk was associated with competition frequency (p = 0.011), injury-related absences (p = 0.002), and EA (p = 0.044). SU included caffeine, cannabis, nicotine, cocaine, ecstasy, and solvents. Gambling risk was associated with younger age (p < 0.001) and EA (p = 0.049). More workouts (p = 0.025) were related to higher EA. Based on these results, we recommend raising awareness, implementing broader screening programmes, and providing educational and support for athletes and staff.

Rainfall duration and parameter sensitivity on flash-flood at a steep watershed

Katalin Bene Gergely Ámon

Publication Name: Pollack Periodica

Publication Date: 2023-07-11

Volume: 18

Issue: 2

Page Range: 54-59

Description:

The common feature of streams in steep sloping watersheds is that there is a significant change from base-flow to flash-flood; sometimes two or three orders of magnitude. In Hungary, these streams are usually ungauged, with lack of available data, and models. The watershed features both urban and natural land use conditions, but the main area is quite homogenic. This paper evaluates the impact of different model parameterizations, and rainfall duration on flash-flood events in the Morgó-creek watershed. The goal is to find the main parameters that can represent the uncertainty of a flash-flood sensitive area, and how the calibrated and determined parameters take effect on a model if these values are shifted on given intervals.

Trademark protection for faces? A comprehensive analysis on the benefits and drawbacks of trademarks and the right to facial image

Barna Arnold Keserű

Publication Name: Journal of Intellectual Property Information Technology and E Commerce Law

Publication Date: 2024-06-01

Volume: 15

Issue: 1

Page Range: 88-99

Description:

The purpose of this paper is to present a comprehensive framework for the possibility of trademark protection for human faces. In the case law of the European Union Intellectual Property Office there are a few examples of trademarks, which consist of only photorealistic human faces. Private law protects the use of images; however, the trends of recent years demonstrate that trademarks could also have a role in such protection. The author aims to analyze the similarities and differences between trademark protection and personality rights in order to determine whether trademarks for faces are necessary or not. The over- arching analysis compares twelve aspects of the two ways in which the legal systems protect facial imagery, highlighting their various advantages and drawbacks. The comparison includes the following attributes: function of protection, scope of protection, territorial dimensions of protection, temporal dimensions of protection, conditions of protection, content of protection, limitations and exceptions, transferability of rights, enforcement of rights, requirement of use, termination of rights and costs.

Page Range: 101-165

Description:

In this work, the hypselostomatid land snail genus Acinolaemus F.G. Thompson & Upatham, 1997 in Southeast Asia is revised. Characters based on which the genus was originally erected are thoroughly examined and evaluated. The genus is subdivided into six species groups based on similarities in shell surface sculpture and apertural barrier morphology. Four out of five species originally described in Acinolaemus, as well as species described from Vietnam and Cambodia are moved to Clostophis. Thirteen new species of Acinolaemus are described as follows: A. altus Gojšina, Hunyadi & Páll-Gergely, sp. nov., A. asper Gojšina, Tongkerd & Páll-Gergely, sp. nov., A. atypicus Gojšina, Tongkerd & Páll-Gergely, sp. nov., A. ferox Gojšina, Tongkerd & Páll-Gergely, sp. nov., A. humilis Gojšina, Hunyadi & Páll-Gergely, sp. nov., A. microcubus Gojšina, Hunyadi & Páll-Gergely, sp. nov., A. paucidentatus Gojšina, Tongkerd & Páll-Gergely, sp. nov., A. profundus Gojšina, Auffenberg & Páll-Gergely, sp. nov., A. rugolabialis Gojšina, Hunyadi & Páll-Gergely, sp. nov., A. simplex Gojšina, Tongkerd & Páll-Gergely, sp. nov., A. singularis Gojšina, Tongkerd & Páll-Gergely, sp. nov., A. solitus Gojšina, Hunyadi & Páll-Gergely, sp. nov., A. zed Gojšina, Hunyadi & Páll-Gergely, sp. nov. Thus, the total number of Acinolaemus species increases to 19, all inhabiting Thailand and Myanmar.

Energy conservative algorithm for numerical solution of ODEs initial value problems

E. M. Miletics

Publication Name: Journal of Computational Methods in Sciences and Engineering

Publication Date: 2005-01-01

Volume: 5

Issue: 1

Page Range: 39-45

Description:

The numerical treatment of the ODE initial value problems is an intensively researched field. Recently the qualitative algorithms, such as monotonicity and positivity preserving algorithms are in the focus of investigation. For the dynamical systems the energy conservative algorithms are very important. In the case of Hamiltonian system the symplectic algorithms are very effective. This kind of algorithm is not adaptive, but doubtless they are powerful. The high-efficiency computers and the computer algebraic software systems allow us to create efficient adaptive energy conservative numerical algorithm for solving ODE initial value problems. In this article an adaptive numerical-analytical algorithm is suggested which very effectively can be applied for Hamiltonian systems, but the idea of construction can be adaptable for other initial value problems too, where there are some quantity preserved in time. The idea and the efficiency of the proposed algorithm will be presented by simple examples, such as the Lotka-Volterra and linear oscillator problems.

Ultrasonic sensor fusion inverse algorithm for visually impaired aiding applications

György Kovács Szilvia Nagy

Publication Name: Sensors Switzerland

Publication Date: 2020-07-01

Volume: 20

Issue: 13

Page Range: 1-16

Description:

Depth mapping can be carried out by ultrasound measuring devices using the time of flight method. Ultrasound measurements are favorable in such environments, where the light or radio frequency measurements can not be applied due to the noise level, calculation complexity, reaction time, size and price of the device, accuracy or electromagnetic compatibility. It is also usual to apply and fusion ultrasound sensors with other types of sensors to increase the precision and reliability. In the case of visually impaired people, an echolocation based aid for determining the distance and the direction of obstacles in the surroundings can improve the life quality by giving the possibility to move alone and individually in unlearnt or rapidly changing environments. In the following considerations, a model system is presented which can provide rather reliable position and distance to multiple objects. The mathematical model based on the time of flight method with a correction: it uses the measured analog sensor signals, which represent the probability of the presence of an obstacle. The device consists of multiple receivers, but only one source. The sensor fusion algorithm for this setup and the results of indoor experiments are presented. The mathematical model allows the usage, processing, and fusion of the signals of up to an infinite number of sensors. In addition, the positions of the sensors can be arbitrary, and the mathematical model does not restrict them to be placed in regular formations.

The Impact Beyond Academia: Patent Citations of the Advanced Pharmaceutical Bulletin

Lóránt Dávid Mehdi Dadkhah Mihály Hegedűs

Publication Name: Advanced Pharmaceutical Bulletin

Publication Date: 2025-01-01

Volume: 15

Issue: 2

Page Range: 223-227

Description:

Purpose: This study aims to analyze the technological impact of papers that Advanced Pharmaceutical Bulletin (APB) has published through patent-to-paper citations analysis. Methods: Current research uses a Scientometric approach to analyze patent citations to published papers by the APB. The Lens has been used for collecting patents that cited related papers. Some of the data analysis was conducted using the Lens analytical tool. Results: Results show that APB’s patent-to-paper citation rate is 32.39%, above the toxicology field average (6.15%) but below pharmacology (46.33%), indicating significant technological influence. APB contributes to both science and technology, attracting global inventors. Conclusion: The patent citations metric can be used to understand how a journal contributes to technological progress. However, these methods need to be standardized and promoted to understand a journal’s real value in technology contribution.

Publication Name: Lecture Notes on Data Engineering and Communications Technologies

Page Range: 27-38

Description:

Wireless Mesh Networks (WMNs) provide seamless connectivity in rapidly changing and dense environments. But when gateways are integrated to provide network access from outside the current topology, several issues become problems. These include maintaining high levels of performance, energy efficiency, security awareness and interconnection. Traditional routing protocols such as Ad hoc On-Demand Distance Vector Routing (AODV) were not able to achieve these two purposes at all in a hybrid setting where efficient communication with the gateway was needed, especially when faced with high mobility, node density and changing traffic loads. This paper introduces that the problem can be resolved by implementing Fuzzy Control Energy Efficient (FCEE) routing in WMNs The FCEE routing method, characteristic innovative energy-efficient real-time failure mechanism and overall network performance enhancement for wireless mesh networks By integrating fuzzy logic into the AODV framework, the FCEE method adds a short-term memory module that optimizes packet broadcasts based on real-time levels of energy available to each node. The FCEE method not only enhances decision-making for packet forwarding but also reduces unwanted broadcasts thus extending the life of the entire network. Simulations show the FCEE performs better than traditional methods in terms of both energy efficiency, congestion control, and adaptability to dynamic situations. The proposed method thus provides an affordable way to improve the operation of wireless mesh networks, particularly in the case of high traffic areas or long periods where resources are constrained.
