Published: March 2024

Infant electrocardiograms (ECGs) and heart rates (HRs) are very useful biosignals for psychological research and clinical work, but can be hard to analyse properly, particularly longform (≥5 min) recordings taken in naturalistic environments. Infant HRs are typically much faster than adult HRs, and so some of the underlying frequency assumptions made about adult ECGs may not hold for infants. However, the bulk of publicly available ECG approaches focus on adult data. Here, existing open source ECG approaches are tested on infant datasets. The best-performing open source method is then modified to maximise its performance on infant data (e.g., including a 15 Hz high-pass filter, adding local peak correction). The HR signal is then subsequently analysed, developing an approach for cleaning data with separate sets of parameters for the analysis of cleaner and noisier HRs. A Signal Quality Index (SQI) for HR is also developed, providing insights into where a signal is recoverable and where it is not, allowing for more confidence in the analysis performed on naturalistic recordings. The tools developed and reported in this paper provide a base for the future analysis of infant ECGs and related biophysical characteristics. Of particular importance, the proposed solutions outlined here can be efficiently applied to real-world, large datasets.

Published: March 2024

In order to achieve the goal of low-carbon, efficient delivery using unmanned vehicles, a multi-objective optimization model considering carbon emissions in the problem of optimizing multi-route delivery for unmanned vehicles is proposed. An improved genetic algorithm (IGA) is designed for solving this problem. This study takes into account constraints such as the maximum service duration for delivery, the number of vehicles, and the approved loading capacity of the vehicles, with the objective of minimizing the startup cost, transportation cost, fuel cost, and environmental cost in terms of the carbon dioxide emissions of unmanned vehicles. A combination encoding method based on the integer of the number of trips, the number of vehicles, and the number of customers is used. The inclusion of a simulated annealing algorithm and an elite selection strategy in the design of the IGA enhances the quality and efficiency of the algorithm. The international dataset Solomon RC 208 is used to verify the effectiveness of the model and the algorithm in small-, medium-, and large-scale cases by comparing them with the genetic algorithm (GA) and simulated annealing algorithm (SA). The research results show that the proposed model is applicable to the problem of optimizing the multi-route delivery of unmanned vehicles while considering carbon emissions. Compared with the GA and SA, the IGA demonstrates faster convergence speed and higher optimization efficiency. Additionally, as the problem’s scale increases, the average total cost deviation rate changes significantly, and better delivery solutions for unmanned vehicles are obtained with the IGA. Furthermore, the selection of delivery routes for unmanned vehicles primarily depends on their startup costs and transportation distance, and the choice of different vehicle types has an impact on delivery duration, total distance, and the average number of trips. The delivery strategy that considers carbon emissions shows a 22.6% difference in its total cost compared to the strategy that does not consider carbon emissions. The model and algorithms proposed in this study provide optimization solutions for achieving low-carbon and efficient delivery using unmanned vehicles, aiming to reduce their environmental impact and costs. They also contribute to the development and application of unmanned vehicle technology in the delivery field.
The Relationship between the Greenhouse Gas and Energy Target Management System and Foreign Ownership: Investor Sensitivity to the Implementation of the System
Authors: Kim Eunsoo
Published: March 2024

As the issue of climate change intensifies, the international community has been actively formulating strategies for mitigation and adaptation. With developed countries leading the way in enforcing stricter greenhouse gas emission regulations, the risks and opportunities associated with climate change have become critical factors in both domestic and international competitive markets. This study examines the investment preferences of foreign investors in companies managed under the Greenhouse Gas and Energy Target Management System (TMS) from 2010 to 2022. Furthermore, it delves into the sensitivity of these investors to the extent of each company’s adherence to the TMS, analyzing this responsiveness in terms of information asymmetry and corporate life cycle. Utilizing a sample of 19,826 firm-year observations from companies listed on the Korea Composite Stock Price Index (KOSPI) and the Korea Securities Dealers Automated Quotations (KOSDAQ) markets, this study’s regression analysis reveals several key findings. Firstly, foreign investors show a preference for investing in companies managed under the TMS compared to those not involved in this system. Secondly, high information asymmetry in the context of TMS implementation negatively impacts foreign investors’ preferences. Thirdly, among TMS-managed companies, foreign investors tend to favor those in the maturity stage of their life cycle. These results suggest that foreign investors perceive the systematic implementation of carbon reduction targets under a government-led TMS as an indicator of a company’s environmental management efficiency, influencing their investment decisions.

Authors: Zhao Zhongyang , Wang Caisheng , Nazari Masoud H.
Published: March 2024

The power system faces a growing need for increased transmission capacity and reliability with the rising integration of renewable energy resources. To tackle this challenge, Battery Energy Storage Systems (BESSs) prove effective in enhancing grid capacity and relieving transmission congestion. This paper focuses on the PJM market, conducting a thorough revenue analysis to identify and characterize highly profitable nodes for BESS market participants. A comparison between stationary and transportable BESSs reveals that the transportable BESSs can generate higher potential revenue in energy and regulation markets. Based on these findings, we propose an optimal placement algorithm to support market participants in selecting strategic sites for BESS installation, validated with real PJM market data. This paper provides valuable insights for navigating market-based power system participants and promoting the effective integration of BESSs.
The Impact of COVID-19 on Attitudes towards Growth Capacity of Tourism Firms: Evidence from Greece
Authors: Gavriilidis Gaby , Metaxas Theodore
Published: March 2024

The aim of this study was to examine the overall impact of the COVID-19 outbreak on the growth capacity of tourism firms in Greece during the first wave of the pandemic. To this end, questionnaires were distributed in 548 tourism enterprises operating throughout Greece within different sub sectors (hotels, travel agents, restaurants, etc.) of the domestic tourism industry. Structural equation modeling (SEM) was employed for analyzing data. The results indicated that COVID-19 negatively influenced the growth capacity of tourism firms, which in turn affected their overall performance. In particular, the negative impact on growth capacity is reflected in dimensions such as managing economic losses and meeting financial obligations. On the other hand, factors such as psychological pressure and fear had no direct impact on the growth capacity of Greek companies during the first wave of the pandemic. A slight association between psychological pressure and growth capacity was detected, which needs further scientific investigation to be supported. Overall, the study highlighted how health crises influence the dynamics and operation of firms operating in the tourism sector, offering useful insights for addressing similar turbulences in future. In this context, domestic tourism authorities should take measurers for improving the growth capacity of Greek firms in periods of turmoil to ensure sustainability in the sector.

Published: March 2024

Habitat mapping plays a crucial role in assessing marine protected areas (MPA) and implementing marine spatial management approaches. This study aims to present the spatial habitat distribution of the Jabal Ali Marine Sanctuary, considering the development projects implemented in its proximity. It serves as a reference for guiding conservation management efforts. The study focuses on in situ hyperspectral measurements of the optical properties of both the water column and the substrate. Additionally, a high density of geo-referenced spot checks were conducted, serving as sample points for ecological evaluation and ground-truthing. An “object-oriented” approach was adopted to generate the seabed map in two evaluated studies conducted in 2006 and 2017. While the 2017 survey identified 16 habitats, the 2006 study characterized only 10 habitats. These habitat maps serve as powerful tools for implementing mitigation measures and providing scientific support to mitigate the negative impact on the most crucial marine habitats within the context of a protected area management framework. Furthermore, monitoring the cover of the most important habitats provides an integrative indicator to maintain the good environmental status of the marine sanctuary. Based on this study, the information will be a reference for evaluating and synergizing the management approaches implemented by both the competent authority and the different stakeholders in the sanctuary.

Published: March 2024

The U.S. Energy Information Administration (EIA) provides crucial data on monthly and annual fuel consumption for electricity generation. These data cover significant fuels, such as coal, petroleum liquids, petroleum coke, and natural gas. Fuel consumption patterns are highly dynamic and influenced by diverse factors. Understanding these fluctuations is essential for effective energy planning and decision making. This study outlines a comprehensive analysis of fuel consumption trends in electricity generation. Utilizing advanced statistical methods, including time series analysis and autocorrelation, our objective is to uncover intricate patterns and dependencies within the data. This paper aims to forecast fuel consumption trends for electricity generation using data from 2015 to 2022. Several time series forecasting models, including all four benchmark methods (Mean, Naïve, Drift, and seasonal Naïve), Seasonal and Trend Decomposition using Loess (STL), exponential smoothing (ETS), and the Autoregressive Integrated Moving Average (ARIMA) method, have been applied. The best-performing models are determined based on Root Mean Squared Error (RMSE) values. For natural gas (NG) consumption, the ETS model achieves the lowest RMSE of 20,687.46. STL demonstrates the best performance for coal consumption with an RMSE of 5936.203. The seasonal Naïve (SNaïve) model outperforms the others for petroleum coke forecasting, yielding an RMSE of 99.49. Surprisingly, the Mean method has the lowest RMSE of 287.34 for petroleum liquids, but the ARIMA model is reliable for its ability to capture complex patterns. Residual plots are analyzed to assess the models’ performance against statistical parameters. Accurate fuel consumption forecasting is very important for effective energy planning and policymaking. The findings from this study will help policymakers strategically allocate resources, plan infrastructure development, and support economic growth.
Relationship of Arable Land Scale and High-Quality Development of Farmers’ Cooperatives: Evidence from Grain Production Cooperatives in China
Authors: Xu Yang , Huo Yujia , Guo Xiangyu
Published: March 2024

Sustainable agricultural development relies significantly on the high-quality progression of farmers’ cooperatives. While growing in number, farmers’ cooperatives are still facing the dilemma of improving the quality of their development. Land endowment is the foundation of agricultural production and the farmers’ cooperatives. Clarifying the correlation between arable land scale and the high-quality development of farmers’ cooperatives is conducive to the optimization of land use and the adoption of scientific land management measures to improve the quality of the development of farmers’ cooperatives. Based on the micro-survey data of 448 farmers’ cooperatives in three major grain-producing provinces, namely Heilongjiang, Henan, and Shandong in China, this paper constructs an evaluation index system for the high-quality development of farmers’ cooperatives and theoretically and empirically explores the impact mechanism of arable land scale on the high-quality development of farmers’ cooperatives. The results suggest the following: (1) there exists a significant “inverted U-shaped” association between the arable land scale and the development quality of cooperatives, and this result remains robust after testing through substitution variable and instrumental variable methods; (2) further research on the “inverted U-shaped” association reveals that the impact of arable land scale on the high-quality development of cooperatives undergoes four stages: “weak impact—rapid improvement—diminished growth effect—decline in development quality”; and (3) mechanism tests suggest that the “inverted U-shaped” association between the arable land scale and the development quality of cooperatives is mainly constrained by industrial development input, and arable land scale and industrial development show a strong complementary relationship. Therefore, in the course of enhancing the quality of farmers’ cooperatives, it is crucial to select appropriate land management strategies based on to their stage, paying special attention to the compatibility between arable land scale and industrial development.
Evaluating the Environmental Factors of Organic Farming Areas Using the Analytic Hierarchy Process
Authors: Shin Eunseo , Shin Yeeun , Lee Sang-Woo , An Kyungjin
Published: March 2024

Sustainable agriculture, including organic farming, offers a potential remedy for addressing environmental pollution. Accordingly, the importance of evaluating the environmental benefits of organic agriculture has become evident. Numerous studies have compared organic and conventional farming or focused on specific crops in environmental studies; however, there is a lack of research on indicators that evaluate the positive impact of organic agriculture on the overall agricultural environment. Therefore, this study aimed to develop comprehensive agri-environmental evaluation indicators by utilizing an analytic hierarchy process (AHP). These methods were employed to determine the importance of factors that evaluate the environmental performance of organic agriculture. This study utilized literature reviews, derived and organized indicators, and prioritized evaluation factors using expert surveys and AHP methods. Based on the analysis of experts, physical and ecological agricultural environments were the most crucial evaluation factors, including biological properties. In addition to the physical ecological agricultural environments, the AHP results demonstrated the need for evaluation indicators that evaluate the overall agricultural environment, including the residential ecological environment and village living and cultural environment. Further empirical studies are required for the derivation of additional valid indicators and policy implementation.
General Relativistic Stability and Gravitational Wave Content of Rotating Triaxial Neutron Stars
Authors: Luo Yufeng , Tsokaros Antonios , Haas Roland , Uryū Kōji
Published: March 2024

Triaxial neutron stars can be sources of continuous gravitational radiation detectable by ground-based interferometers. The amplitude of the emitted gravitational wave can be greatly affected by the state of the hydrodynamical fluid flow inside the neutron star. In this work, we examine the most triaxial models along two sequences of constant rest mass, confirming their dynamical stability. We also study the response of a triaxial figure of quasiequilibrium under a variety of perturbations that lead to different fluid flows. Starting from the general relativistic compressible analog of the Newtonian Jacobi ellipsoid, we perform simulations of Dedekind-type flows. We find that in some cases the triaxial neutron star resembles a Riemann-S-type ellipsoid with minor rotation and gravitational wave emission as it evolves towards axisymmetry. The present results highlight the importance of understanding the fluid flow in the interior of a neutron star in terms of its gravitational wave content.

This study contextualizes the transformative role of Business Intelligence (BI) over the past two decades, emphasizing its impact on business strategy and competitive advantage. Employing a dual-method approach, it integrates a bibliometric analysis using SciMAT with a qualitative examination of six key articles from the Web of Science (WoS), analyzed through the Gioia methodology, focusing on BI and competitiveness. The aim is to examine the metamorphosis of Business Intelligence (BI) and how it has evolved from a traditionally supporting role to a central strategic player in shaping corporate strategy and business competitive advantage over the past two decades. It discusses the overall transformation of BI and provides an in-depth examination of the specific ways in which Business Intelligence tools have redefined the landscape in contemporary business practices. Key findings reveal BI’s pivotal role in enhancing knowledge management, innovation, and marketing capabilities. Challenges in BI implementation, such as the necessity for skilled personnel and adaptability to swift technological shifts, are also highlighted. Results advocate for a dynamic BI approach, adaptable to market trends and technological evolutions. The research demonstrates that BI tools, especially when integrated with technologies like AI, IoT, and machine learning, significantly enhances decision making and efficiency in socio–technical and management systems, leading to a paradigm shift in handling complex systems and adapting to changing environments.
The Quantum Hall Effect under the Influence of Gravity and Inertia: A Unified Approach
Authors: Landry Alexandre , Hammad Fayçal , Saadati Reza
Published: March 2024

The quantum Hall effect under the influence of gravity and inertia is studied in a unified way. We make use of an algebraic approach, as opposed to an analytic approach. We examine how both the integer and the fractional quantum Hall effects behave under a combined influence of gravity and inertia using a unified Hamiltonian. For that purpose, we first re-derive, using the purely algebraic method, the energy spectrum of charged particles moving in a plane perpendicular to a constant and uniform magnetic field either (i) under the influence of a nonlinear gravitational potential or (ii) under the influence of a constant rotation. The general Hamiltonian for describing the combined effect of gravity, rotation and inertia on the electrons of a Hall sample is then built and the eigenstates are obtained. The electrons mutual Coulomb interaction that gives rise to the familiar fractional quantum Hall effect is also discussed within such a combination.

Published: March 2024

A critical discussion on the H0 Hubble constant tension is presented by considering both early and late-type observations. From recent precise measurements, discrepancies emerge when comparing results for some cosmological quantities obtained at different redshifts. We highlight the most relevant measurements of H0 and propose potential ideas to solve its tension. These solutions concern the exploration of new physics beyond the ΛCDM model or the evaluation of H0 by other methods. In particular, we focus on the role of the look-back time.

Wild rodents are considered to be one of the most important TBEV-amplifying reservoir hosts; therefore, they may be suitable for foci detection studies. To investigate the effectiveness of viral RNA detection in wild rodents for suspected TBEV foci confirmation, we trapped small rodents (n = 139) in various locations in Lithuania where TBEV was previously detected in questing ticks. Murine neuroblastoma Neuro-2a cells were inoculated with each rodent sample to maximize the chances of detecting viral RNA in rodent samples. TBEV RNA was detected in 74.8% (CI 95% 66.7–81.1) of the brain and/or internal organ mix suspensions, and the prevalence rate increased significantly following sample cultivation in Neuro-2a cells. Moreover, a strong correlation (r = 0.88; p < 0.05) was found between the average monthly air temperature of rodent trapping and the TBEV RNA prevalence rate in cell culture isolates of rodent suspensions, which were PCR-negative before cultivation in cell culture. This study shows that wild rodents are suitable sentinel animals to confirm TBEV foci. In addition, the study results demonstrate that sample cultivation in cell culture is a highly efficient method for increasing TBEV viral load to detectable quantities.

During the COVID-19 pandemic, immunosuppressed patients showed prolonged SARS-CoV-2 infections, with several studies reporting the accumulation of mutations in the viral genome. The weakened immune system present in these individuals, along with the effect of antiviral therapies, are thought to create a favourable environment for intra-host viral evolution and have been linked to the emergence of new viral variants which strongly challenged containment measures and some therapeutic treatments. To assess whether impaired immunity could lead to the increased instability of viral genomes, longitudinal nasopharyngeal swabs were collected from eight immunocompromised patients and fourteen non-immunocompromised subjects, all undergoing SARS-CoV-2 infection. Intra-host viral evolution was compared between the two groups through deep sequencing, exploiting a probe-based enrichment method to minimise the possibility of artefactual mutations commonly generated in amplicon-based methods, which heavily rely on PCR amplification. Although, as expected, immunocompromised patients experienced significantly longer infections, the acquisition of novel intra-host viral mutations was similar between the two groups. Moreover, a thorough analysis of viral quasispecies showed that the variability of viral populations in the two groups is comparable not only at the consensus level, but also when considering low-frequency mutations. This study suggests that a compromised immune system alone does not affect SARS-CoV-2 within-host genomic variability.

Purpose: To evaluate the effect of a multi-component educational program aimed at improving general practitioner (GP) trainees’ (registrars') deprescribing in patients 65 years and over. The hypothesis was that an educational program would increase registrars' deprescribing of potentially inappropriate medicines (PIMs) in older patients, relative to a control group, six months post-education.
Design: This was a pragmatic, non-randomised, non-equivalent control group design nested within an ongoing cohort study of registrars' practice (the ReCEnT study). The program consisted of an online module, face-to-face sessions for registrars, webinars for their supervisors, and facilitation of the registrar–supervisor dyad, including case-based discussions of deprescribing in teaching meetings. The program was underpinned by the Behaviour Change Wheel framework and delivered to registrars of a single registrar educational/training organisation (other educational/training organisations served as controls). Primary outcome measures were deprescribing any medicines and deprescribing medicines categorised as PIMs. Secondary outcomes were deprescribing of medications taken for three months or more and dose reduction with a view to deprescribing (cessation).
Findings: Data from 779 education-receiving registrars and 438 control registrars were analysed. Intervention group registrars showed no significant increase in deprescribing of any medication compared to controls (interaction aOR 1.00 (95%CI 0.69, 1.46) or of PIMs (aOR 1.29 (95%CI 0.74, 2.24), or significant changes in secondary outcomes.
Research implications: Despite no differences in prescribing, in this analysis, six months post-intervention, aspects of the findings suggest extended observation and further evaluation may be indicated.
Practical implications: The continuation of education for registrars around deprescribing of PIMs is essential. Further investigation is required to assess the effectiveness and efficiency of the behaviour change approach adopted in this study.
Originality/value: The multi-component behaviour change theory-based approach is novel for this educational setting, and this is an initial step in evaluating the approach.
Limitations: The major limitation is that randomisation in the study design was not practicable.

Key Points

In unadjusted analyses, elevated urinary Dickkopf-3 levels were strongly associated with higher risks of cardiovascular disease, ESKD, AKI, and mortality.

However, associations were substantially weakened after adjustment for eGFR and albuminuria, suggesting limited prognostic value.

Background

Urinary Dickkopf-3 (uDKK3) is a tubular epithelial-derived profibrotic protein secreted into the urine under tubular stress. It is associated with kidney disease progression in persons with CKD and diabetes and postoperative and contrast-associated AKI. We explored associations of uDKK3 with cardiovascular disease (CVD), kidney, and mortality outcomes within the subset of Systolic Blood Pressure Intervention Trial participants with nondiabetic CKD.

Methods

We included 2344 participants with eGFR <60 ml/min per 1.73 m2 at baseline. We used Cox proportional hazards models to evaluate associations of uDKK3 with CVD (acute decompensated heart failure, myocardial infarction, acute coronary syndrome, stroke, or CVD death), kidney outcomes (incident ESKD, incident AKI, and eGFR decline ≥30%), and all-cause mortality. We used linear mixed models to examine the association of uDKK3 with annual percentage change in eGFR. Models were adjusted for demographic and clinical characteristics, eGFR, and albuminuria.

Results

Over a median follow-up of 3.5 years, there were 292 CVD, 73 ESKD, 183 AKI, 471 eGFR decline, and 228 mortality events. In multivariable models without adjustment for eGFR and albuminuria, uDKK3 was strongly associated with CVD, ESKD, AKI, eGFR decline ≥30%, and mortality. However, after further adjustment for eGFR and albuminuria, uDKK3 was no longer associated with risks for composite CVD (hazard ratio, 1.07; 95% confidence interval, 0.92 to 1.23), ESKD (0.80; 0.62 to 1.02), AKI (1.01; 0.85 to 1.21), eGFR decline ≥30% (0.88; 0.79 to 0.99), or mortality (1.02; 0.87 to 1.20). For the linear eGFR change outcome, higher uDKK3 also had no association in the fully adjusted model (−0.03; −0.41 to 0.36).

Conclusions

Among individuals with hypertension and nondiabetic CKD, higher uDKK3 appeared to have associations with a greater risk of CVD events, incident ESKD, incident AKI, eGFR decline ≥30%, and mortality but these associations were not independent of eGFR and albuminuria.
