A Health Economics Inquiry into Regulatory Constraints on the European Tobacco Market
Authors: Barbaro Salvatore , Neu-Yanders Nathalie , König Nina 
Published: November 2024

Abstract
Despite the implementation of significant measures by European countries in recent years, smoking rates in Europe remain persistently high. The European Commission is currently undertaking a comprehensive review of its tobacco regulations. This article aims to address critical inquiries that arise during the amendment of the regulatory framework. We evaluate the effectiveness of existing tobacco control methods and observe a diminishing impact on promoting smoking cessation. Additionally, we explore how individuals of varying genders respond to the regulatory environment. We propose a comprehensive and evidence-based framework for implementing a taxation system in response to the proliferation of emerging products, including e-cigarettes and heated tobacco. This system is designed to align effectively with health policy objectives, providing a strategic approach to curbing tobacco use and promoting public health.
Monitoring of coccinellid (Coleoptera) presence and syrphid (Diptera) species diversity and abundance in southern California citrus orchards: implications for conservation biological control of Asian citrus psyllid and other citrus pests

Abstract
The abundance and diversity of three taxa of citrus pest predators, syrphids (Diptera), coccinellids (Coleoptera), and chrysopids (Neuroptera) and their association with flowering weed species in commercial citrus orchards in southern California were investigated. The occurrence and frequency of adult predators were determined with vertical yellow sticky traps and by performing 3 min visual counts on flowering weeds from May through November 2021. Syrphid abundance peaked in June and September, with the dominant species being Allograpta obliqua (Say), Toxomerus marginatus (Say), and Paragus tibialis (Fallen). Peak collections of coccinellids occurred in May, June, and September on sticky traps and during September and October in flowering weedy plants. Peak flowering of weed species occurred during May and declined sharply over summer into fall (June–November). The efficacy of yellow 355 mL glycol pan traps, yellow 1774 mL water pan traps, and yellow sticky traps orientated either horizontally or vertically with respect to capturing key natural enemies was evaluated in 2021 and 2022. Significantly more syrphids were captured on the horizontal yellow sticky traps than on the vertical yellow sticky traps or the yellow pan traps filled with glycol or water. Coccinellids were most frequently captured on vertical yellow sticky traps and yellow water pan traps. Numbers of chrysopids captured in all studies were not significant, which was most likely attributable to their nocturnal behavior. Collectively these results suggest that syrphid and coccinellid activity in southern California citrus orchards displayed two seasonal peaks, one in spring and the other in the fall. In the context of future conservation biological control, insectary plantings in spring (April–June) and fall (September–October) would be most beneficial to these predators and would coincide with population peaks of a key citrus pest, Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae).

Published: November 2024

Abstract
In this paper, a type of reconfigurable filtering phase shifters (RFPSs) composed of stepped-impendence stub-loaded multimode resonators (SLMMR) is proposed. High frequency selectivity and wideband characteristics are realized in the presented work. Four transmission poles (TPs) are generated in the passband to exhibit a flat and wide passband. Meanwhile, the proposed SLMMR produces two controllable transmission zeros (TZs), which improves the frequency selectivity effectively. Meanwhile, radiofrequency switches are utilized to facilitate the transition between different phase shifts. Finally, the proposed RFPSs are designed and fabricated to verify the method. The measured results indicate that the designed RFPSs, which can be turned from 45° to 90° and from 135° to 180°, are capable of realizing more than 40 % FBW with a center frequency of 3.5 GHz.

Published: November 2024

Abstract
The hot compression behavior of 316LN stainless steel for the supporting system in a magnet confinement fusion reactor was isothermally compressed at 1,050℃ and 0.1 s−1. Electron backscatter diffraction was used to study the microstructure and texture evolution during the deformation process. The results showed that the necklace structure is eventually formed by increasing compression strain due to dynamic recrystallization (DRX). The proportion of low-angle grain boundaries first increases and then decreases. The dominant DRX mechanism of 316LN is discontinuous DRX, which is characterized by the grain boundary bulging. Besides, twinning is found to be induced to accommodate the plastic strain, helping the development of DRX.

Authors: Tang Wenwei , Zhang Peiqi , Xia Jin , Zeng Xinping 
Published: November 2024

Abstract
The residual manganese concentration from groundwater treatment plants normally exceeds the limit of 0.1 mg L−1, which is the maximum permissible manganese content set by the Ministry of Health. A new biological activated carbon fiber technology is described in this paper, in which filtration columns filled with ACF and inoculated manganese oxidizing bacteria (Citrobacter sp. FM-2) were used in an attempt to effectively remove the Mn2+ in groundwater using a biological method. By researching the various factors that influence biological manganese removal, a new kinetics model of BACF filtering with multiple influencing factors that incorporates the key factors of the process, such as the temperature, pH and empty bed contact time (EBCT), was established, and the accuracy of the model was verified. The study further extends the research on biological manganese removal and provides a reference and basis for production practice to some extent.

Published: November 2024

Abstract

Hipposideros spp. are insectivorous bats and karst cave dwellers. This study aimed to study the roosting ecology, reproduction, and population fluctuations of three species H. diadema, H. larvatus, and H. ater in Gunung Sewu Karst region, Indonesia. Age and reproductive status of individuals were identified and analyzed using a combination of forearm length (FA) and body mass grades (W). Multiple regression analysis was used to determine the correlation between population size, rainfall and population structure based on FA, reproductive status, and W. Crude birth rate (CBR) and general fertility rate (GFR) were used to determine the population’s birth rate and female fertility. The results showed that the population of the three Hipposideros species were quite stable over the year with a peak in January which classified them as monoestrous, with mating, pregnancy, and lactation occurring once a year with no delay between mating and pregnancy. Pregnancy lasted 8–12 weeks and lactation 4–5 weeks. The population structure of the three species tended to be stable over the year. The CBR and GFR values can be used for rapid assessment guidelines in an area.
Understanding the Meaning of “Aspeset”: Hermeneutical Approaches, Reading Practices and the Departure from Germany in Two Lea Goldberg Novels
Authors: Keren Yaara 
Published: November 2024

Abstract
This essay describes the departure from Europe, arguably the theme that unites Lea Goldberg’s three novels, in terms of the German tradition of Hermeneutics. I explore the various hermeneutical approaches in two of the novels, Mikhtavim Minesi’a Meduma and Avedot, and connect their metafictional and metacritical debates to the circumstances of their composition, publication and reception. While Mikhtavim Minesi’a Meduma employs a humanistic and universalist Weltliteratur perspective in order to downplay the emotions of bitter rejection from a beloved cultural home, Avedot contends with hermeneutical and philological questions ranging from authenticity and interpretation to the mystery of artistic creation. Avedot’s plot revolves around the philologist-poet protagonist’s quest for his own pseudo-ancient text, but ultimately raises questions about the spiritual nature of the creative process and whether or not this spiritual baggage can be relayed to an external reader, in political circumstances that accentuate the poet’s sense of alienation. The two novels, with their unstable form, provided Goldberg an opportunity not only to contemplate aesthetic questions, but also to psychologically process the tearing away from the cultural and intellectual legacy of Europe and in particular that of Germany.

Authors: Tsantiri Konstantina , Kokla Vasiliki , Karabotsos Athanasios 
Published: November 2024

Abstract
Toned photographs became popular in the second half of the 19th and early 20th century, either as stand-alone photographic images or as part of representative cards such as cabinet cards or cartes de visite. Still, further research is desirable to deepen our understanding about materials and techniques that had been used to create toned photographs. This study focusses on toning processes and is based on the analysis of 16 historical photographs from that period. To understand the toning process, information was collected from historical literature, while multispectral techniques and SEM/EDS analysis were applied to the sixteen photographs. Multispectral techniques, both macroscopic and microscopic, provide valuable information on surface and texture, damage phenomena and the photograph’s stratigraphy. SEM/EDS analysis yields information on the elements found in the studied photographs and their stratigraphy. This combination of the evaluation of historical written sources and scientific analysis provided an insight into the materials and techniques used in the toning of photographs.

Authors: Gama Alessandra Regina , Sobrinho Gilberto Alexandre , Nogueira Lisandro 
Published: November 2024

Neste artigo, abordamos a representação da cosmogonia afro-brasileira em documentários, considerando aspectos estéticos e políticos da relação entre o cinema e os terreiros. Nosso objetivo é refletir sobre as questões de representação das culturas afro diaspóricas no campo documental, entrelaçadas ao campo teórico das performances culturais, na conformação de uma estética de encruzilhada. Partindo da ideia de cinema como um ponto de intersecção, como cinema de encruzilhada, analisamos a trilogia documental produzida pela Sociedade de Estudos da Cultura Negra no Brasil — SECNEB, no final dos anos 80, composta pelos filmes Orixá Ninu Ilê (Dir. Juana Elbein dos Santos, 1978), Iyá-Mi-Agbá (Dir. Juana Elbein dos Santos 1981) e Egungun (Dir. Carlos Brajsblat, 1982). A trilogia explora as disputas em torno dos modos de representação do conhecimento ancestral, refletindo, nas obras, o embate entre cinema e descolonização cultural, do ponto de vista das relações entre corpo e performance, na articulação de saberes.

Published: November 2024

AbstractThe aim of our research is to fill the research gap on how successful businesses have been affected by the challenges posed by COVID-19 regarding the resilience and adaptability of firms. Since 2016, the Budapest Stock Exchange (BSE), with the collaboration of EY, selects a number of unlisted companies (BSE50) per year that have Hungarian roots and are considered successful based on their operations and ability to increase sales. We examined the impact of COVID-19 on profitability, liquidity, indebtedness and change in turnover or EBITDA based on four years (2018–2021) of financial data from 252 non-financial, unlisted companies. In addition to the descriptive statistics, a two-sample asymptotic z-test was used to compare the periods before and during COVID-19. We divided the BSE50 companies into Dynamics and Laggards based on the change in turnover between 2019 and 2020. The Dynamics of the pandemic have emerged from the challenging period of COVID-19 as real champions, taking advantage of their low level of indebtedness by making efficient use of loan possibilities. Even the Laggards were able to rebalance and consolidate their financial position by the second year of the pandemic. Our study is novel because we used data on Hungarian, non-financial, unlisted companies with successful management to examine the impact of COVID-19 on hard-hit firms as well as on firms in the winning branch.

In this work, the Quality Function Deployment (QFD) and Failure Mode and Effects Analysis (FMEA) methodology based on the «Design for X» concept is studied to define the design criteria of the mechanical characteristics of an EOD robot and validated with a virtual prototype of an Explosive Ordnance Disposal (EOD) robot. The objective is the application of this methodology to obtain a product that meets the quality and reliability specifications, considering the user’s needs as input data. To validate this methodology, the technicians of the UDEX (Explosive Ordnance Disposal Unit), the mechanical characteristics of the previous version JVC 0.2 developed by the research team of the National University of San Agustin (UNSA), the minimum specifications of the robots participating in the League of Rescue Robots and the application to work in real environments were taken as a case study. The results indicate that the application of the proposed methodology has significantly improved the quality and reliability of the design. To validate the effectiveness of this methodology, a virtual prototype, called JVC 0.3, was created using SolidWorks modelling software, a significant weight reduction of 27.13 % was achieved and the operating speed was increased to 1 km/h under optimal conditions. Technical analysis of the JVC 0.3 showed significant improvements in several key areas, such as increased modularity for easier assembly and maintenance, decreased overall weight, increased torque and speed, and increased stability during operation. These factors are essential for the practical application of EOD robots in real field operations carried out by specialized units such as UDEX

Published: November 2024

In this study, a large-scale magnetic rotator for hydrogen production boosting was designed. The study addresses the challenge of selecting and designing mechanical components for a dynamic magnetic field (DMF) magnetic rotator in a green hydrogen electrolysis power plant, focusing on ensuring component reliability and efficiency under operational stresses. The aim is to determine suitable machine element materials (shaft, clutch, gears, etc.), allowable shear stress, and interconnection mechanisms through theoretical and practical evaluations. The method includes calculating the allowable shear stress for the spline based on carbon steel tensile strength, applying safety factors for material properties and load considerations, and determining shaft diameter using torque and shock load factors. Standard catalogs guide the selection of interconnections like clutches, gears, and bearings to ensure compatibility and performance. The results indicate that a 95 mm diameter S30C carbon steel shaft, with an allowable shear stress of 7.8 kg/mm2, meets the design requirements. The chosen spline dimensions and a 12.5 MW, 14-pole induction motor align with the system’s needs, ensuring reliable operation. The discussion highlights the critical balance between theoretical predictions and practical application in design optimization. It underscores the importance of incorporating safety factors and verifying component suitability to ensure robust performance of the magnetic rotator. This study provides a comprehensive approach to design optimization, integrating theoretical analysis with practical considerations to achieve optimal performance and reliability. The design output of this study can be used to boost the hydrogen evolution reaction in the SIEMENS Sylizer 300 electrolysis cell.

MIMO (Multiple Input Multiple Output) makes a major contribution to 5G communication systems by increasing network capacity and spectrum efficiency. In 5G, MIMO enables the use of multiple antennas at base stations and user devices, allowing simultaneous sending and receiving of data over multiple paths. This significantly increases data throughput and connection reliability, especially in environments with high user density. In addition, MIMO technology supports the implementation of beamforming, which focuses signals on a specific direction, reduces interference, and improves signal coverage and quality, making it one of the keys to achieving faster and more responsive 5G performance. Therefore, antennas with wide bandwidth, high gain and MIMO performance are crucial for supporting 5G communication systems. This paper proposes a high-performance MIMO microstrip antenna based on a series planar array with 8×2 elements operating at a resonant frequency of 3.5 GHz for 5G communication systems. A spiral stub and a feed inset are proposed to control the reflection coefficient and bandwidth of the antenna while the series planar array is proposed to increase the gain. To support the MIMO communication system, the proposed antenna is separated into two different ports with a certain distance. From the measurement results, the proposed antenna has high performance indicated by a wide bandwidth of 680 MHz (3–3.68 GHz) and a high gain of 17.8 dB at a resonant frequency of 3.5 GHz. In addition, the proposed antenna has high mutual coupling and diversity indicated by ECC and DG of 0.001 and 9.99 dB, respectively. This work provides a solution to design a high-performance microstrip antenna and can be implemented as a receiving antenna for 5G communication systems

This research focuses on optimizing ultra-wideband (UWB) antennas, which are critical in modern communication systems due to their wide frequency range (3.1–10.6 GHz) and high data transmission capabilities. The study addresses the challenge of optimizing key antenna parameters – such as return loss, peak gain, and radiation efficiency – while also ensuring energy efficiency and network longevity. Traditional optimization methods, such as LEACH-C, often fail to balance these factors, leading to suboptimal performance.
To solve this problem, the researchers developed the Generalized Position-based Optimization Neural Network (GPON) for UWB antenna optimization. They also evaluated the Position-based Hybrid Neural Network (PAN) method, comparing its performance with existing algorithms including LEACH-C, Firefly Algorithm (FA), HFAPSO, FA-ANN, and HWOABCA. The GPON model reduced return loss to 25.5 dB at 3.5 GHz and improved peak gain to 4.2 dB i, while maintaining 92 % radiation efficiency. In contrast, PAN demonstrated a 15–25 % improvement in residual energy and extended network lifetime by 20 % compared to LEACH-C.
These improvements were due to the integration of advanced neural network techniques in GPON and the effective use of positional data in PAN, enabling more precise and adaptive optimization. The ability to balance multiple performance metrics simultaneously – a challenge previous models struggled with – is a key feature. This balance is crucial for UWB antennas in communication systems where both performance and energy efficiency are vital. The findings are especially relevant for practical applications in wireless sensor networks, mobile communications, and radar systems, requiring long-term network reliability and optimal antenna performance
