Authors: Sasaki Jun  , Takahashi Shizune  , Yamada Keizo  , Takagi Masanori
Published: February 2025

The authors developed a system for collecting and analyzing photo and check-in data to represent location data in a heat map. In addition, the authors classified traveler profiles and analyzed their data for display as a heat map for each classification. To verify whether the findings would be consistent with actual travelers' intentions, a questionnaire was carried out for people living in Iwate Prefecture, Japan. This paper compares the results of the data collected by the system with the actual intentions of travelers as obtained from the questionnaire. It is confirmed that check-in data for women and young people correspond closely with the intentions of travelers revealed by the questionnaire.
The Challenge of Creating the Cyprus Academic Library Consortium (CALC): Impacts and Benefits
Authors: Zervas Marios  , Haraki Maria
Published: February 2025

This paper describes the development of the Cyprus Academic Libraries Consortium (CALC) and the process of formulating its own agreements with Publishers, but not before explaining how the Public Universities of Cyprus managed to participate in the Hellenic Academic Libraries Link (HEAL-Link) Consortium. Insufficient funds, lack of organization, danger of overlapping information resources, create a slow growth rate and obstacles in the provision of information material by Academic Libraries to their users. Realizing these problems and trying to avoid them CALC was created – comprised of seven members, with its main action limited only to subscriptions to Electronic Resources. Furthermore, criteria are outlined describing reasons for choosing services and electronic resources from Publishers. Also, the dissemination of cost per member institution for each deal is described through a formula created by the library directors and agreed to by the senate of each member institution. Although there are benefits of academic libraries joining the CALC consortium, the fact that there are practical and financial problems as well as challenges is not ignored. Methods, such as an evaluation on the usage of the resources and promotion of the same, must be applied by the librarians of each university consortium member. Qualitative methods are discussed and quantitative methods are presented as essential, to better evaluate the impact of resources in the research area (Cost Benefit Analysis (CBA) and Return on Investment (ROI) formulas). With attention to situations like the overcoming of the Swets (CALC's main supplier) bankruptcy, the paper continues to show that success can be achieved through proper record keeping, hard work and good relations – which is how CALC managed to continue its subscriptions to the Publishers and avoided any interruption of access to the electronic journals. Although setting up a consortium can provide many benefits, CALC is also in the process of acquiring its Legal Entity in order to be better able to process its administrative and cost actions. Further development and future actions are mentioned, including discovering how researchers are using the library's resources to help with their teaching and research.
New Toolkits on the Block: Peer Review Alternatives in Scholarly Communication
Authors: Schmidt Birgit  , Görögh Edit
Published: February 2025

Peer review continues to play a central role in scholarly communication processes, however, over the last decade the concept has branched out in terms of methods, platforms and stakeholders involved. The paper demonstrates how alternative peer review tools and methods are instrumental in further shaping the communication of scholarly results towards Open Science. The analysis is based on the examination of various review methods (peer commentary, post-publication peer review, decoupled review, portable or cascading review) and review tools and services (publishing platforms, repository-based, and independent reviews). Besides the differences in operation and functionality, these new workflows and services combine common features of network-based solutions and collaborative research applications with varying degrees of openness (e.g. regarding participation, identities and/or reports). They, therefore, represent good examples of Open Science, in terms of transparency and networking among researchers.
Software Protection Against Illegal Copy Using Software Watermarking

Published: February 2025

In this paper, we propose software protection algorithm against illegal copy by unauthorized persons using software watermarking. In the proposed scheme, the software license information, related to the media access control (MAC) address and software product-key, is embedded into the software logotype image as a watermark sequence. At the first stage of the software execution, the watermark sequence is extracted from the logotype and compared with the current MAC address of the hardware devise. If the extracted MAC address differs from the hardware's MAC address, then the software displays a warning message related to the invalid license and finalizes its execution, otherwise the software continues its normal operation. The performance of the proposed scheme is analyzed from the difficulty of software piracy and reverse engineering points of view, and the evaluation results show the effectiveness of the proposed algorithm.
Low Carbon Intensity Routes via Ocean Currents and Waves
Authors: Mannarini Gianandrea  , Pinardi Nadia  , Coppini Giovanni
Published: February 2025

The VISIR ship routing model is augmented with the capability to employ, on top of waves, also ocean currents for optimising vessel routes. A case study for a cargo vessel sailing between the Chesapeake Bay (USA) and Lisbon (Portugal) is considered. The seasonal variability of the route pattern is visualised, with the major ocean boundary current impacting in a specific way, depending on the prevailing sailing direction. In the approximation of CO2emissions proportional to sailing time, the impact on the Energy Efficiency Operational Indicator (EEOI) proposed by the International Maritime Organization is also computed. The seasonal variability of EEOI demonstrates, for a given parametrisation of vessel energy loss in waves, potential savings in the 3–12% range, with respect to navigation along a least-distance route, and in the 1–5% range, with respect to navigation along a least-time route which neglects the role of ocean currents. These figures refer to monthly mean values, while individual routes may exhibit EEOI savings up to 20% and 6%, respectively.
Effect of Different Propulsion Systems on CNG Ships Fleet Composition and Economic Effectiveness
Authors: Mauro Francesco  , Trincas Giorgio  , Braidotti Luca
Published: February 2025

The compressed natural gas (CNG) transport is becoming nowadays an attractive solution not only for stranded gas shipping where current technologies like liquefied natural gas (LNG) and pipelines are not economically competitive, but also for long-enough distance transport of large volumes of natural gas, where LNG still represents the most economical solution. In fact, recent studies on pressure vessels (PV) materials allow to significantly reduce the ship displacement in case of PVs Type 3 and Type 4 when compared to existing prototype designs with PVs Type 1 and Type 2, also leading to completely different hull forms. Since CNG ship design is a new research field for Naval Architecture, the concept design phase assumes an utmost importance with respect to design of well-known ship types, not only for the main parameters determination and performances assessment, but also for the study of completely different solutions for some subsystems. To this purpose, the present paper presents a technical-economic comparison between two different kinds of propulsion systems: conventional diesel drive propulsion with propellers and a complete diesel electric solution with pods. The differences between the two solutions are influencing both internal layout and ship dimensions, leading to two completely different ship concepts. These have been compared to determine the most cost effective solution not only for the single CNG ship but mostly for the fleet composition in a given transport scenario.
3D Adaptive Coverage Planning for Confined Space Inspection Robots
Authors: Pivetta Rowan  , Lammas Andrew  , Sammut Karl
Published: February 2025

The manual inspection of confined spaces, such as ballast tanks, for corrosion is a hazardous, time consuming, expensive, and subjective process. Robotic inspection techniques are being considered as they promise greater objectivity and comprehensive coverage as well as repeatability, reduced risk, and shorter maintenance downtime. To enable a robot to comprehensively inspect all surfaces within the tank, it needs an inspection plan. Although coverage planning algorithms can be used to automatically generate optimal plans, complex environments and robot kinematics can make the problem challenging. Most existing coverage algorithms can only produce offline plans, however these cannot cope with unforeseen obstacles and would consequently fail when placed in modified environments. Such problems present the need for adaptive coverage-planning algorithms that can replan routes autonomously. To date, the focus of our research has been to evolve an offline redundant roadmap based algorithm into an enhanced algorithm capable of adapting its plan online. The online solution utilises LIDAR scan updates to rectify compromised paths through region-based replanning, allowing localised replanning around identified areas of change without recalculating the whole tour from scratch. Preliminary results reveal that the online planner is capable of replanning multiple regions concurrently, faster, and with minimal path degradation compared to its offline counterpart.

Published: February 2025

The aim of the paper is to describe an industry-academic collaboration to conduct a research project whose main goal is the design of a new escort tug family characterized by high intact/damage stability margins, good maneuvering capability and stable behavior during escort indirect assistance. The project is focused on three main research areas: hydrodynamic design and internal subdivision of the hull, simulation of the escort capabilities in different operational scenario, development of control logics that will allow autonomous or unmanned operations. The paper describes the methodological approach adopted for the design and will show some preliminary results. The tug has been designed to be in compliance with new amendments of the 2008 Intact Stability Code (Res. MSC.415(97)) which will enter into force on 1st January 2020) both for towing and for escort operations. Furthermore, a significant step towards enhancement of ship's safety is granted by tug's capability to withstand a damage in accordance with criteria applicable to OSVs. This paper describes the prototype hull and its stability characteristics. CFD calculations and towing tank tests have been performed in order to assess the hull design and to infer simulation models able to describe the behavior of a family of vessels. In particular, the propulsion and maneuverability aspects in escort operations are deeply investigated. Results of the project will form the bases for the conceptual application to a remotely controlled or autonomous escort tug.

Non-Contact Heart Rate Measurement Based on Facial Video
Authors: Zhou Nan  , Huang Lei  , Huang Jifeng  , Pan Tao  , Ni Yepeng  , Shan Lianhai
Published: February 2025

Heart rate measurement is an important means of monitoring the physiological status of the human body. A non-contact heart rate measurement method is proposed by analyzing the change of pixels. Multi-filter and sub-region method are adopted to solve the problem of the complex heart rate signal extraction result. As the independence of the RGB color model, the green component signals can be taken from the mixed signals by using Fast ICA. The main peak noise is removed by the wavelet filtering and the band-pass filter, and the heart rate is obtained in the analysis of the energy spectrum by using the Fourier transform. The facial organs influence on the extraction of the heart rate signal is effectively reduced by dividing the face region, and the part of the face to best reflect the heart rate is further determined. The experimental results show that this method can be convenient and accurate to achieve the heart rate measurement, and the proposed division method of the most appropriate facial part to extract the heart rate enhances the application of the heart rate measurement.

Published: February 2025

Pomegranate (Punica granatum), commonly known as “Anar”, is an ancient fruit. It is preferably consumed due to its pleasing taste and high nutritious value along with some other associated health benefits. These benefits are not only meant for human beings, however, also for the fish. In recent times, scientific interest in pomegranate and its consumption has increased due to its numerous health benefits. Therefore, the current study aimed to review the most recent literature on different properties of the pomegranate. These properties include antimicrobial and antioxidant activities, its effect on hematological and growth parameters along with the role of pomegranate as a preservative in fish and fish products. The current study evaluated previously conducted studies to determine the effect of pomegranate on different systems of fish. Results showed that the intake of pomegranate effectively increased the growth of juvenile fish and dietary value of fish, boosted the hematological and immune responses, as well as feed efficiency and antioxidant activity. Moreover, it also showed antioxidant properties and proved effective for the preservation of fish fillets by reducing lipid oxidation, chemical degradation, and microbial growth in stored fish. Therefore, the incorporation of pomegranate in fish food has numerous applications. However, additional research is required to ascertain the safe limits.
Mechanisms of Glycolysis and Fermentation: A Non-Equilibrium Thermodynamics Perspective
Authors: Roosterman Dirk , Cottrell Graeme S.
Published: February 2025

Every single chemical formula of modern models of glycolysis violates the scientific rules formulated by Newton (Physics) and Lavoisier (Chemistry). Yet, the formulae of the pioneers who investigated metabolism did not violate the laws of nature. Recently, the well-established models of metabolism have collapsed by re-introducing hydrogen (Chemistry, Physics) as the energy entity driving the Krebs-cycle (Biochemistry). This review builds on a scientific concept of metabolism by introducing that glycolytically generated energy is either transformed into ATP or drives a biological process. The dynamic production and utilization of lactate (lactate flow non-equilibrium) is introduced as a central ATP-driven process and the first step of biosynthesis. A metabolism model based on non-equilibrium thermodynamics replaces the current understanding that one end product of glycolysis is consumed by mitochondria with two intermediates of the two-cell model of metabolism that are consumed by mitochondria. The pyruvate dehydrogenase complex, consuming pyruvic acid, saves one redox unit (2H) for storage as lipid or glycogen, whereas mitochondrial consumption of lactic acid enhances ATP recovery. An uncounted number of signalling pathways temporarily regulate the distribution of this single redox unit. Glycogenolysis massively impacts the flow non-equilibrium, an event permanently memorized by cells. The two-cell model of metabolism starts to functionally unite fields such as memory formation, obesity, exercise, schizophrenia, cancer, and inflammation by the common denominator: metabolism.

Hospitality businesses in emerging economies have adopted digital tools to improve service delivery, customer satisfaction, and stakeholder trust, prompting scholars to conduct empirical research to strengthen their resilience, particularly in Nigeria. This research investigated the effect of digital business transformation (DBT) on business resilience in an emerging business economy with perceived organizational support (POS) as a moderating role using a cross-sectional survey. The study focused on workers from selected hospitality businesses in Abakaliki, southeastern Nigeria, using simple random sampling to choose the businesses. Participants' demographics were analyzed with frequency distribution, and research hypotheses were tested using Partial Least Squares-Structural Equation Modeling (PLS-SEM). The study revealed that POS provides resources that moderate the effect of DBT on business resilience. Consequently, the study recommends that the management of hospitality firms should focus on DBT to help the firms to be resilient. This can be achieved through using digital tools, knowledge, skills, and processes to improve the turbulence-handling capability of the firm

Focusing on Generation Z consumers in Malaysia, this study investigates the role of brand awareness in shaping customer loyalty and purchase intention for Starbucks. The research method involved a multi-stage sampling procedure targeting Generation Z consumers in Malaysia (born 1997–2012) with recent Starbucks purchase experiences, using a pretested online survey to collect 101 valid responses from urban centers like Kuala Lumpur, Penang, and Johor Bahru. The results reveal that brand awareness enhances customer loyalty and fosters brand trust development. The brand trust serves as a powerful catalyst for brand engagement and customer loyalty, while brand engagement emerges as a crucial driver of both loyalty formation and purchase intentions. Customer loyalty exhibits a positive influence on purchase intention. These findings advance brand relationship theory by demonstrating the sophisticated pathways through which brand awareness influences behavioral outcomes among Generation Z consumers, highlighting the crucial mediating roles of trust and engagement. This research contributes to brand management literature by offering a nuanced understanding of how brand relationships develop among digital-native consumers while providing practical guidance for companies seeking to strengthen customer relationships in increasingly competitive markets
УПРОВАДЖЕННЯ АНГЛІЙСЬКОЇ ЯК МОВИ ВИКЛАДАННЯ: ВИКЛИКИ Й ПЕРЕВАГИ
Authors: Bortnyk Svitlana , Hikov Leonid
Published: February 2025

У статті розглядаються деякі підходи до використання англійської мови як мови викладання (EMI) фахових предметів на вищому рівні освіти. Головною метою програм EMI є як отримання студентами професійних знань, так і вдосконалення володіння англійською мовою для подальшої глобальної інтеграції. Дослідження феномену EMI можна розділити на три основні групи: дослідження щодо мовної політики та програм особливо у вищій освіті; дослідження щодо студентів, їх розуміння і ставлення до ЕМІ, їхній рівень володіння мовою й наявні мовні навички, стратегії навчання, результати й очікування; дослідження, що стосуються вчителів вищої освіти та їхнього розуміння EMI, володіння мовою й здібностей, стратегій і методів викладання, потреби в нових педагогічних навичках. Більшість досліджень стосовно впровадження EMI наголошують на необхідності вдосконалення мовних навичок як викладачів, так і студентів. Деякі спеціалісти вважають, що EMI було б ефективно впроваджувати разом із викладанням частини матеріалу й рідною мовою (code-switching), виділенням більше часу на вивчення теми, пояснення та відгуки студентів. Перефразування вважається більш доцільним прийомом, тому що передбачає не перехід на рідну мову, а вміння пояснити нове слово, використовуючи вже знайому лексику. Але всі ці методи можливі за умови глибокого знання ESP і хорошого володіння спеціалізованою термінологією. Існує низка переваг як для студентів, так і для викладачів, незважаючи на всі труднощі впровадження EMI. Робота з програмами EMI – це не просто рух у напрямі іншомовної політики. Реалізація цього методу навчання можлива за умови спільної діяльності й співпраці вчителів англійської мови та вчителів змісту – професіоналів своєї справи.

Quantifying changes in fish population stability using statistical early warnings of regime shifts
Authors: Walter Jonathan , Lewis Levi , Hobbs James , Rypel Andrew
Published: February 2025

Ecological conservation and management benefits from tools that can foresee impending problems, or those in early stages. Statistical early warnings of regime shifts, which can identify generic changes in system behavior associated with stability loss and potential abrupt changes to a new, distinct state, are theoretically well grounded and have been successfully applied in real-world settings. However, early warning indicators have seldom been applied to empirical animal population data. We quantified early warning metrics in 29 fishes using > 4 decades of monitoring data from the San Francisco Estuary and Sacramento-San Joaquin river system to develop an index describing the magnitude of evidence of population stability loss and potential regime shifts, relative to other studied species. Spatial synchrony increased in over twice as many species as it decreased, but temporal variance and lag-1 autocorrelation showed no tendency to have increased across species species. A composite early warning indicator (EWI) index developed from these metrics identified higher-risk species (e.g., white croaker, tule perch) from lower-risk ones (e.g., northern anchovy, fathead minnow). The composite index was uncorrelated with long-term abundance trends or whether the species is native or non-native. We also developed an index of confidence in the composite EWI score; considering both the EWI score and confidence index simultaneously suggests possible responses for research and management. For high EWI score, high confidence species may be candidates for targeted research and interventions, while high EWI score, low confidence species may be candidates for enhanced monitoring to better constrain population dynamics. Despite concerns about attributing changes in EWI metrics to regime shifts in short time series, there appears to be value in applying generic EWIs to population time series of animals with generation times ≥ 1 year, and approaches like ours may be valuable when little is known about organism life history, and when applying a consistent protocol can facilitate comparison across many species.
Advanced AI-Driven Credit Risk Assessment for Buy Now, Pay Later (BNPL) and E-Commerce Financing: Leveraging Machine Learning, Alternative Data, and Predictive Analytics for Enhanced Financial Scoring
Authors: Md Rakib Mahmud  , Md Refadul Hoque  , Tanvir Ahammad  , Md Nazmul Hasan Hasib  , Md Minzamul Hasan
Published: February 2025

The increasing adoption of Buy Now, Pay Later (BNPL) and other financing models in e-commerce presents new challenges in credit risk assessment. Traditional credit scoring models often fail to capture the financial behavior of unbanked or underbanked consumers, necessitating innovative AI-driven approaches (Abbott, 1991). This study explores the integration of deep learning, alternative data sources, and reinforcement learning to enhance credit risk analysis for BNPL financing. By leveraging non-traditional financial indicators such as transactional data, digital footprints, and behavioral analytics, AI-driven credit assessment models can improve predictive accuracy and mitigate default risks (Barakat et al., 1995). The research employs a hybrid methodology combining supervised deep learning techniques with reinforcement learning algorithms to refine credit decision-making (Medvec et al., 1999). Findings indicate that AI-powered financial scoring significantly enhances risk assessment precision compared to conventional models, reducing default rates and improving financial inclusivity. These insights contribute to the ongoing discourse on AI applications in financial technology, offering practical implications for e-commerce platforms, lenders, and regulatory bodies.

ПОЛІФУНКЦІЙНІСТЬ WAR-RELATED COLLOCATIONS У МОВІ ВІЙНИ
Authors: Дем’янчук Юлія Ігорівна , Кучеренко Марина Володимирівна
Published: February 2025

Дослідження присвячене випрацюванню функцій war-related collocations (політично-оцінних прагматизмів) в офіційно-діловому, публіцистичному та художньому дискурсі, що ретранслюють уявлення про внутрішній потенціал мови війни. Лінгвістичні одиниці викликають зацікавлення у різних аспектах – і з боку пізнання воєнних, антитерористичних, миротворчих дій й збройної боротьби в цілому, і в плані увиразнення притаманних певному класу слів лексико-семантичних ознак в процесі інформаційного обміну між органами державної влади, військовим командуванням, військовими адміністраціями, органами місцевого самоврядування та міжнародними партнерами й організаціями, що забезпечують координацію дій, своєчасне реагування на загрози та стратегічне планування. Аналіз лінгвістичних параметрів тексту уможливлює структурувати новосформовані смисли, заразом актуалізує семіосферу, що дає ключ до означення воєнного і політичного явища, яким є російсько-українська війна. Новизна дослідження полягає у встановленні поняття war-related collocations та їхнього функціонального потенціалу у мові війни. У межах стилістичного аналізу предметом дослідження слугують – мовні засоби теорії оперативного мистецтва (операцій і бойових дій), теорії тактики (підготовка й ведення бою) й теорії стратегій (управління військами). Для виявлення й систематизації war-related collocations використано загальнонаукові методи спостереження й опису мовних явищ, стилістичного аналізу із застосуванням прийомів внутрішньої інтерпретації. На наше переконання, вербалізація елементів воєнно-політичної системи ґрунтується на військовій риториці, що формується внаслідок тривалої, постійно відтворюваної взаємодії між мовою та воєнною реальністю у висвітленні бойового досвіду Збройних Сил України й набутого досвіду “виживання” цивільних під час масових ракетних обстрілів. Перспективи подальшого студіювання убачаємо в ґрунтовному дослідженні war-related collocations крізь призму лінгвістики війни – виявленні математично-статистичних закономірностей виокремлення колокацій на основі парадигмальної трансформації. Аналіз таких мовних фактів має різноплавні інтенції у методологічному аспекті: увиразнить комунікативно-когнітивну природу мовних одиниць; розкриє лінгвальну природу засобів лінгвополітичної номінації.

This study evaluates the accuracy and explanatory power of price-earnings, price-to-book, and price-to-sales models. Most research focused on developed countries, while only limited studies compared equity valuation models in developing countries. Those studies show mixed and inconclusive results. Moreover, most studies on stock valuation models are primarily concerned with the model's accuracy but not their explanatory performance. Therefore, this study aims to determine the most suitable stock valuation models for accuracy and explanatory performance using data from medium and large banks in Indonesia. This is the first study to examine both stock valuation models’ accuracy and explanatory performance in Indonesia. The data employed in this study are from 13 medium and large banks listed on the Indonesia Stock Exchange from 2012 to 2021. This study compares the models based on absolute prediction error and root mean square error to determine accuracy. It also evaluates the models using panel data regressions to determine the explanatory performance of each model. The findings reveal that the price-earnings model is superior to the accuracy and explanatory power of price-to-book and price-to-sales models. The price-earnings model has the lowest prediction errors, and it has the highest R-square compared to the other models. Based on the empirical findings of this study, the price-earnings model outperforms price-to-book and price-to-sales models in terms of accuracy and explanatory power. This suggests that the price-earnings model is the most suitable for conducting a stock valuation analysis of the banking sector in Indonesia.
