Improving battery safety and sustainability through testing material advances and industry developments

Zoltán Weltsch Tibor Cseke Robert Kun

Publication Name: Discover Sustainability

Publication Date: 2025-12-01

Volume: 6

Issue: 1

Page Range: Unknown

Description:

The transition to renewable energy is essential for sustainable development, in which advanced energy-efficient storage solutions, in particular rechargeable batteries, play a key role. Batteries are becoming increasingly important not only for electric mobility and grid balancing, but also for industrial and residential applications. However, as energy density increases, so do safety risks such as thermal runaway, which can jeopardise user confidence. The aim of this study is to examine the battery technology value chain at a systemic level, with a particular focus on the role of safety testing and technological innovation. The research identifies three main gaps in literature: the lack of value chain level integration, the under-representation of AI-based safety technologies, and the limited comparison of regional (EU, US, Asia) regulatory regimes. By examining the interrelationships between material selection (cathode, anode), cell design, testing protocols and regulatory environment, the study highlights the complex challenges and development directions for battery energy storage. The study reviewed global industry trends and critically assessed forecasts and analyses from international consultancies such as Ernst & Young (EY). These concluded that thorough testing of lithium-ion batteries is key to ensuring long-term reliability, safety and performance by reducing operational risks and increasing product efficiency. Advanced testing infrastructure not only serves quality control and regulatory compliance, but also makes a fundamental contribution to increasing energy efficiency and supporting the green transition. For Europe in particular, it is of paramount importance to expand testing capacities to enable the continent to take a leading role in the safe and sustainable development of batteries.

An intelligent traffic congestion detection approach based on fuzzy inference system

Miklós F. Hatwágner Gergely Mikulai Mehran Amini László T. Kóczy

Publication Name: Saci 2021 IEEE 15th International Symposium on Applied Computational Intelligence and Informatics Proceedings

Publication Date: 2021-05-19

Volume: Unknown

Issue: Unknown

Page Range: 97-104

Description:

Traffic congestion causes significant economic and social consequences. Instant detection of vehicular traffic breakdown has a pivotal role in intelligent transportation engineering. Common traffic estimators and predictors systems need traffic observations to be classified in their binary-set-nature computation methods which are unable to be an effective base for traffic modeling, since they are defined by precise and deterministic characteristics while traffic is known to be a highly complex and nonlinear system, which may be prescribed by uncertain models containing vague properties. This study aims at applying a new fuzzy inference model for predicting the level of congestion in such heterogeneous and convoluted networks, where the paucity of accurate and real-time data can cause problems in interpreting the whole system state by conventional quantitative techniques. The proposed fuzzy inference model is based on real data extracted from Hungarian network of freeways. As input variables traffic flow and approximate capacity of each segment are considered and level of congestion is regarded as output variable. In the model, a total number of 75 rules were developed on the basis of available datasets, percentile distribution, and experts' judgments. Designed model and analyzing steps are simulated and proven by Matlab fuzzy logic toolbox. The results illustrate correlations and relationships among input variables with predicting the level of congestion based on available resources. Furthermore, performed analyses beside their tractability in dealing with ambiguity and subjectivity are aligned with intelligent traffic modeling purposes in designing traffic breakdown-related alert or early warning systems, infrastructure and services planning, and sustainability development.

Approaches to studying wheat and maize drought stress responses

I. Gergely G. Takács Levente Vörös József Iváncsics Vince Ördög

Publication Name: Plant and Soil

Publication Date: 2025-11-01

Volume: 516

Issue: 1

Page Range: 115-132

Description:

Introduction: Drought stress remains a critical challenge to sustainable agriculture worldwide, threatening crop productivity and food security. Understanding the physiological processes and defense mechanisms that crops employ under water-limited conditions is essential for developing strategies to enhance drought resilience. Plant responses to drought vary widely depending on species, genotype, developmental stage, and the severity and duration of stress. Beyond annual rainfall totals, yield is also shaped by seasonal precipitation patterns and related environmental factors, which influence the choice of cultivars and crop performance. Finding: This review examines the drought responses of maize and wheat, two globally important cereals, across morphological, physiological, biochemical, and molecular dimensions. Key responses include enhanced root development, reduced leaf area, stomatal regulation, decreased photosynthetic activity and water potential, and elevated proline and abscisic acid levels. Although varietal differences are noted, they are discussed only briefly. Water stress is commonly quantified via water potential and measured using tools such as the Scholander pressure chamber or the increasingly adopted ZIM probe, which allows non-destructive, continuous monitoring. While conventional breeding efforts have targeted drought tolerance, progress is constrained by these traits' polygenic and environmentally sensitive nature. Recently, biostimulants such as seaweed extracts and microalgae-based products have emerged as promising tools for enhancing stress tolerance. Conclusion: To meet the demands of a changing climate, future research should prioritize the integration of genetic, physiological, and biochemical strategies to develop crops with robust and durable drought resistance.

Kibble–Zurek scaling due to environment temperature quench in the transverse field Ising model

Ádám Bácsi Balázs Dóra Balázs Dóra

Publication Name: Scientific Reports

Publication Date: 2023-12-01

Volume: 13

Issue: 1

Page Range: Unknown

Description:

The Kibble–Zurek mechanism describes defect production due to non-adiabatic passage through a critical point. Here we study its variant from ramping the environment temperature to a critical point. We find that the defect density scales as τ-dν or τ-d/z for thermal or quantum critical points, respectively, in terms of the usual critical exponents and 1 / τ the speed of the drive. Both scalings describe reduced defect density compared to conventional Kibble–Zurek mechanism, which stems from the enhanced relaxation due to bath-system interaction. Ramping to the quantum critical point is investigated by studying the Lindblad equation for the transverse field Ising chain in the presence of thermalizing bath, with couplings to environment obeying detailed balance, confirming the predicted scaling. The von-Neumann or the system-bath entanglement entropy follows the same scaling. Our results are generalized to a large class of dissipative systems with power-law energy dependent bath spectral densities as well.

On the Impact of Packet Reordering in MPT-GRE Multipath Networks

Naseer Al-Imareen G. Lencse

Publication Name: 2023 46th International Conference on Telecommunications and Signal Processing Tsp 2023

Publication Date: 2023-01-01

Volume: Unknown

Issue: Unknown

Page Range: 82-86

Description:

Several factors, such as network delays, congestion, differing path lengths, and varied processing durations at intermediary nodes, can cause out-of-order arrival of the packets, negatively affecting network performance, decreasing throughput, and increasing latency. When packets arrive out of order, the receiver may need to wait for missing packets before assembling a complete message, resulting in additional delays. Furthermore, some applications, like music and video streaming, require continuous and ordered data flow. Any out-of-order arrival of packets can result in jitter and decreased quality. To mitigate the impact of this issue in MPT-GRE multipath networks, MPT contains a packet reordering mechanism. In this paper, we designed a network topology that generated delays and limited the transmission speed on one of the paths. We investigated how the out-of-order arrival of packets influences the throughput aggregation capability of the MPT library with and without enabling the packet reordering feature of MPT. Our network throughput measurements show that by enabling MPT's packet reordering mechanism, MPT can efficiently aggregate the throughput of both symmetric and asymmetric channels.

The impact of the coronavirus pandemic on the mental health of critical care workers

Zana Ágnes Szvath Petra Takács Szabolcs Hermann Csaba Mátay Gábor Bódi Bernadett

Publication Name: Orvosi Hetilap

Publication Date: 2023-10-22

Volume: 164

Issue: 42

Page Range: 1646-1655

Description:

Introduction: The coronavirus pandemic has focused attention on the importance of critical care and highlighted the shortage of critical care specialists. Due to increasing workloads and high mortality rates, healthcare professionals were exposed to higher levels of physical and psychological stress during the pandemic than before. Objective: Our study investigated the effects of the coronavirus outbreak on the emotional, mental and moral stress of intensive care professionals. Method: Our workgroup performed paper-based surveys among caregivers in the Department of Anaesthesiology and Intensive Therapy at Semmelweis University. The first survey was conducted at the start of the pandemic in 2020, the second survey was conducted after the third wave in 2021. We applied validated questionnaires (Professional Quality of Life, Demoralization Scale, Perceived Stress Scale, Impact of Event Scale, and Posttraumatic Growth Inventory), collected demographic data and information on lifestyle, recreation, dietary habits, and accepting psychological support. Results: The number and demographic characteristics of the participants in the two studies are different, reflecting the changes in the workforce during the pandemic. Our results revealed no differences between the working and socio-demographic groups before the outbreak, however, one year later, nurses scored significantly higher on all negative psychological scales compared to other groups. Only a minority of the respondents had sought psychological support (9.5–12.7%), although more than a third of respondents reported the need for psychological support. Employees in new work positions showed significantly increased posttraumatic growth (2.91 ± 0.82 vs. 2.20 ± 1.06, p = 0.016). Discussion: These findings demonstrate that nurses are the most strained workgroup during an uncertain and stressful period. The available mental support alone is not enough to help caregivers. Conclusion: Further steps are needed to improve the mental health of critical care workers

Description:

Patients are central to healthcare services, and comprehending their perceptions is crucial for fostering effective value co-creation. This study aimed to investigate the user characteristics and perceptions of value co-creation within the context of Mobile Electronic Health Records (EHR). Using a questionnaire collected from 422 patients, the study employed the K-modes clustering algorithm in R-Studio to group users based on shared characteristics and perceptions of value co-creation. The analysis revealed three distinct user clusters, which are high familiarity-positive perception, low familiarity-positive perception and high familiarity-neutral to negative perception. These clusters characterized by unique attributes such as socio-economic, history of medical visit, intention to use, technological familiarity, and different perception of value co-creation in Mobile EHR systems. Descriptive statistics were used to further interpret the clusters, revealing differences in user characteristics and perception across cluster. The findings emphasize the importance of alignment between user expectations and system interactions. Effective alignment fosters value co-creation through resource access, sharing, integration, and recombination, while misalignment may result in value destruction. This study highlights the need to design and implement Mobile EHR systems that align with the diverse characteristics and of their users to enhance engagement and promote value co-creation.
