Integration of social and cultural dimensions in the assessment of environmental flows: case of the Ouémé delta in West Africa
Authors: Sossa Fidèle , Djihouessi Metogbe Belfrid , Tasso Florent B. , Kouaro Monique Ouassa 
Published: January 2024

AbstractThe use of environmental flows as a technique for the diagnosis and sustainable management of aquatic ecosystems in West Africa is relatively new and cautious, despite being broadly implemented for many years in Western countries and Southern Africa. The present study, the first to evaluate the environmental flows in Benin, concentrates on the deltaic region of the Ouémé River. The assessment utilises the Building Block Methodology approach, and incorporates ecological, socio-cultural, and religious dimensions. The assessment focuses on the alterations in river flows and the impact on local communities’ livelihoods, beliefs, and cultural and religious practices. The results indicate that the population of the Ouémé Delta are significantly impacted by changes in the river’s flow. Indeed, floods play a crucial role in people’s daily routines and livelihoods, while a significant decrease in river flow results in economic instability. Moreover, there is a strong link between specific religious customs in the area and the river’s flow. To maintain the current provisioning, regulating, and cultural ecosystem services in the Ouémé delta, The study recommended to allocate 100% of the River Ouémé’s natural flow during low-water periods (December to May) and 50% of the natural flow during high-water periods (June to November). This allocation ensures that the environment’s water needs are met and will contribute to preserve the Ouémé delta’s ecosystem, ensuring the sustainability of its ecological habitats and biodiversity. However, the implementation of these recommendations would require more debate and a real consensus on the priority between development and environment.
Unveiling narratives: representation of same-sex love in bollywood films
Authors: V Prasitha , G Bhuvaneswari 
Published: January 2024

AbstractThe cultural history of India has been ignorant of various sexual orientations and gender identities leaving LGBTQIA+ (Lesbian, Gay, Bisexual, Transgender, Queer, Intersex, Asexual) community with a life of guilt and shame. Visual Media plays a key role in shaping society’s opinion of LGBTQIA+ people and individuals who come to terms with their gender and sexuality at a particular phase of their lives. The representation of homosexual characters is constantly diversified in Bollywood, and the change is evident from being caricatured and even scorned to being shown as prominent protagonists. The growing visibility and the positive portrayal of homosexual characters in Bollywood help to create a more inclusive society. This paper focuses on the select Bollywood films, Ek Ladki Ko Dekha Toh Aisa Laga (2019) by Shelly Chopra Dhar and Shubh Mangal Zyada Saavdhan (2020) by Hitesh Kewalya. The paper analyses the visual elements in select films and their role in shaping the portrayal of homosexuality within the narrative. The paper also reads the chosen films through the lens of familial resistance to same-sex relationships. By analysing the select films, the paper concludes that, though prior Bollywood films have explored the theme of individuals disclosing their sexual identity to their families, the primary narrative focus is not on seeking acceptance from their family members. Thus, the unique emphasis on seeking acceptance and understanding between family members and homosexual individuals set the select films as exceptional narratives within the context of Bollywood’s portrayal of homosexuality.
Development of a machine learning finite-range nonlocal density functional
Authors: Chen Zehua , Yang Weitao 
Published: January 2024

Kohn–Sham density functional theory has been the most popular method in electronic structure calculations. To fulfill the increasing accuracy requirements, new approximate functionals are needed to address key issues in existing approximations. It is well known that nonlocal components are crucial. Current nonlocal functionals mostly require orbital dependence such as in Hartree–Fock exchange and many-body perturbation correlation energy, which, however, leads to higher computational costs. Deviating from this pathway, we describe functional nonlocality in a new approach. By partitioning the total density to atom-centered local densities, a many-body expansion is proposed. This many-body expansion can be truncated at one-body contributions, if a base functional is used and an energy correction is approximated. The contribution from each atom-centered local density is a single finite-range nonlocal functional that is universal for all atoms. We then use machine learning to develop this universal atom-centered functional. Parameters in this functional are determined by fitting to data that are produced by high-level theories. Extensive tests on several different test sets, which include reaction energies, reaction barrier heights, and non-covalent interaction energies, show that the new functional, with only the density as the basic variable, can produce results comparable to the best-performing double-hybrid functionals, (for example, for the thermochemistry test set selected from the GMTKN55 database, BLYP based machine learning functional gives a weighted total mean absolute deviations of 3.33 kcal/mol, while DSD-BLYP-D3(BJ) gives 3.28 kcal/mol) with a lower computational cost. This opens a new pathway to nonlocal functional development and applications.
Foreword to the Special Issue on ‘Fertility control for wildlife in the 21st century’

Published: January 2024

The economic and environmental impacts of wildlife are increasing in parallel with renewed public interest in non-lethal methods, such as fertility control, to manage these impacts. The Wildlife Research 2008 Special Issue on Fertility Control for Wildlife (Vol. 35) published following the 6th International Conference on Fertility Control for Wildlife held in 2007 in York, United Kingdom, reported studies on the effects of contraceptives on individual animals and populations, with most papers focusing on ungulates. In the past 15 years, significant progress has been made in developing novel contraceptives for wildlife and in designing methods to deliver these agents. Concurrently, the general debate on wildlife management has widened to include public attitudes and perceptions of novel and traditional methods, animal welfare issues, costs, feasibility, and regulatory and ethical issues. These developments have broadened our understanding of contexts and species for which fertility control could be employed, either as a stand-alone method or to complement other population management options. These topics were reflected in the presentations given at the 9th International Conference on Wildlife Fertility Control, held in Colorado Springs (USA) in 2022. Here, we introduce a special issue featuring selected presentations from the 2022 conference. These studies showcase the wide spectrum of topics that covered novel contraceptives tested on several species, ranging from mice to elephants. They also illustrate new methods to deliver contraceptives, models on the impact of fertility control on populations, feasibility, cost of practical applications of fertility control, discussions on animal welfare and human dimension of these approaches.
Michael Halliday
Authors: Tsui Amy B. M. 
Published: January 2024

Abstract
It is a huge honour and an immense privilege to contribute to this special issue on Michael Halliday’s hitherto unpublished work, “Exploring the ‘language’ part of language education”, not least because the paper was conceptualised in response to what he had observed over a period of three years (1997–2000) as External Examiner for the B.Ed. (Language Education) programme from 1997–2000 at my university – the University of Hong Kong. In this short piece, I will provide the context for Halliday’s paper, which may help readers to better understand the motivation that inspired it and his frequent reference to the Hong Kong situation. I will also draw on the comments he made in his examiner’s reports that are in a way precursors to the expositions in this paper.1

Exploring the “language” part of language education
Authors: Halliday M. A. K. , Williams Geoff 
Published: January 2024

Abstract
This paper is based on a series of lectures Halliday presented in the Faculty of Education, University of Hong
Kong in 2005. As Amy Tsui indicates in her companion paper in this issue, it was to have been the first chapter in a book that
would also include chapters by other scholars discussing the educational use of some of Halliday’s theoretical and practical
proposals, but for various reasons the book did not eventuate. (See also the first sentence of the paper.) One distinctive feature
of the paper is its reach over a very large range of concepts in Halliday’s theory. Another is its accessibility for educators
looking to find a general introduction to aspects of systemic functional linguistic theory relevant to education. The final
section illustrates the analytical use of the theory in various educational contexts through examples of discourse analyses.1
Cyclic voltammetry signal analyses for equivalent electric circuits consisting of multiple resistors and capacitors
Authors: Wong Ten It , Zhou Xiaodong 
Published: January 2024

Abstract
An equivalent circuit is a combination of resistors, capacitors, inductors, Warburg impedance, and constant phase elements, which are widely measured and analyzed to understand the electrochemical (EC) properties of materials such as batteries, thin films, or corrosion. An equivalent electric circuit is also built as different dummy cells to evaluate the measurement accuracy of EC instruments with key detection modes, including electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). Dummy cell signals for EIS can be easily understood and simulated by existing EIS signal analysis software, while dummy cell signals for CV curves have no simulation formula so far. When using dummy cells for CV tests, users can only observe if the CV curves obtained seem to be correct, which impairs the accuracy and efficiency of quality as well as the ability to confirm the functionality of an EC instrument. In this study, we conducted CV signal analyses on five cases of equivalent circuits consisting of multiple resistors and capacitors, with their correctness verified by dummy cell experiments using two different potentiostats. Based on the measured CV signals, we further demonstrated a data process method to evaluate the performance of a potentiostat quantitatively and automatically. This study enables researchers to calculate CV curves of resistors and capacitors formed by EC equivalent circuits, and provides a quantitative method to verify whether an EC instrument is functioning well.
Contribution of BDS-3 observations to the precise orbit determination of LEO satellites: a case study of TJU-01

Published: January 2024

Abstract
The precise orbit determination (POD) of scientific low Earth orbit (LEO) satellites is a prerequisite for the successful implementation of scientific missions. In recent years, global navigation satellite systems have become the main means of determining the orbits of LEO satellites. The global navigation satellite system receiver onboard the Tianjin University No. 1 (TJU-01) satellite receives both GPS and BDS-2/3 signals, with the addition of BDS-2/3 observations playing an important role in improving the POD of LEO satellites. This study comprehensively analyzes the spaceborne GPS/BDS data quality, including BDS-2/3 and GPS code multipath errors. Appreciable code multipath errors are found for the B1I signal of BDS-2 medium Earth orbit (MEO) satellites at elevations higher than 40°, whereas slight near-field relevant multipath errors of both frequencies are found for GPS and BDS-3 MEO satellites. The GPS and BDS-2/3 code multipath errors are estimated through elevation/azimuth-relevant piece-wise modeling and applied in the POD calculations. Several schemes, namely GPS-based, BDS-based, BDS-based without geo-synchronous (GEO) satellites, and GPS/BDS combined schemes, are designed to evaluate the POD performance. Fourteen days of data are calculated and the average three-dimensional (3D) orbital root mean square (RMS) of orbit overlapping differences obtained from GPS-based and BDS-based POD (without GEO satellites) solutions are 37.4 and 27.1 mm, respectively. The BDS-based solutions are obviously better than the GPS-based solutions, mainly owing to better data availability. The GPS/BDS combined solutions have the best accuracy, with a 3D RMS value of 20.6 mm. In addition, when BDS GEO satellites are included, the 3D RMS of the overlapping orbit differences reduces to 32.9 and 27.4 mm for BDS-based and GPS/BDS combined solutions, respectively. Double-difference (DD) and single-difference (SD) integer ambiguity resolution (IAR) are adopted to further improve the POD performance. The fixed orbit of the TJU-01 satellite is solved through DD IAR and SD IAR, and the contribution of the TJU-01 satellite to ambiguity fixing is analyzed. Relative to the float solution, the improvements made using the two ambiguity fixing approaches are equivalent, both being approximately 13%. The importance of this research is not only the precise determination of the orbit of TJU-01 for occultation service but also the demonstration of the contribution of BDS observations to the performance of the POD of LEO satellites.

Variable stiffness structure inspired by seashells
Authors: Pagliarani Niccolò , Arleo Luca , Luca Giovanna De , Pozzi Jasmine , Cianchetti Matteo 
Published: January 2024

Abstract
Variable stiffness is typically employed in soft robotics to address the trade-off between compliance and the ability to generate stability when required. Among the several approaches investigated, jamming transition systems show remarkable stiffness performance and fast response. Building upon the preliminary study on a seashell bioinspired variable stiffness structure, here we extend the design space through a parametric study supported by a finite element model based on commercially available software. The study allows establishing the relationship between the design parameters and the stiffness performance. Moreover, the optimal configuration in terms of performance to energy consumption is identified and compared to previous similar approaches. Finally, the low computational cost of the finite element model demonstrated to be an effective tool for the analysis of complex geometries, thereby establishing a foundation for the development of cost-effective and lightweight soft robotic devices empowered by variable stiffness capabilities (e.g. a wearable device for assistance).
Bismuth sulfide/carbon black: as a pt free and efficient counter electrode in DSSC
Authors: Shaikh Rahilah S , Rajput Rekha B , Kale Rohidas B 
Published: January 2024

Abstract
A hydrothermal method was utilized to synthesize microstructures of bismuth sulfide (Bi2S3) across a range of reaction temperatures, spanning from 140 to 180 °C. The impact of varying reaction temperatures on the structural, morphological, and optical properties of the deposited Bi2S3 material was thoroughly examined. The x-ray diffraction (XRD) patterns confirmed the presence of an orthorhombic crystal structure. The formation of intricate three-dimensional Bi2S3 microstructures was evident under field emission scanning electron microscopy (FESEM), with the reaction temperature playing a pivotal role in this process. Furthermore, Bi2S3-carbon black composites were employed as the counter electrode in dye-sensitized solar cell (DSSC) applications. The current density–voltage characteristics of the DSSCs revealed a clear correlation between photoconversion efficiency and the reaction temperature. Notably, the Bi2S3-carbon black film with a 1:1 ratio achieved a peak photoelectric conversion efficiency of 4.37 ± 0.01%. It also exhibited a short-circuit current density of 10.29 mA cm−2 and an open-circuit potential of 0.70 V. Future studies should explore the broader implications of Bi2S3-carbon black composites in various optoelectronic and photocatalytic devices. Secondly, while our findings provide valuable insights, a more in-depth understanding of the underlying mechanisms governing the enhanced photoconversion efficiency, especially with the 1:1 ratio of Bi2S3-carbon black, requires further exploration.

Published: January 2024

Abstract
The double perovskites have emerged as focal point of exploration and innovation in energy harvesting applications. In this paper, we elucidate the mechanical, optical, and transport properties of Li2AgGaX6 (X = Cl, Br, I) through the application of DFT-based simulations by employing the WIEN2K software. The calculation of formation energy has been conducted to assess thermodynamic stability. The band structures of studied halides doped double perovskites have reported values of direct band gaps. These findings have implications for a variety of optoelectronic and transport applications due to their diverse characteristics. The peaks of the absorption band are shifted toward the lower frequency spectrum, and their width increases as we shift from Cl to I. Furthermore, thermoelectric attributes such as the Seebeck coefficient (S), power factor (σS2), and figure of merit (ZT) have been evaluated across the thermal spectrum range (200–600) K Low value of thermal conductivity and substantial ZT at standard temperature (300 K) indicate their profound significance in thermoelectric developments.
Mid-range wireless power transfer: anapoles or magnetic dipoles?
Authors: Ha-Van Nam , Simovski Constantin R , Asadchy Viktar S , Tretyakov Sergei A 
Published: January 2024

Abstract
For short-range wireless power transfer (WPT) one recently suggested so-called anapole antennas that practically do not create fields in the far zone, eliminating radiation loss. Enhancements of power transfer efficiency (PTE) compared to traditional WPT systems based on magnetic dipole antennas were claimed for distances of the order of one-tenth of the wavelength or smaller. In this Letter, we theoretically show that a system of two properly engineered magnetic dipole antennas grants a similar PTE for this range of distances and a higher PTE for larger distances. In addition, we demonstrate that at mid-range distances, the radiation from magnetic-dipole-based WPT systems can be made drastically lower than the radiation from a single magnetic dipole antenna. This regime offers an alternative for reduction of far-field radiation.
Energy spectrum of some diatomic molecules using Nikiforov-Uvarov functional analysis
Authors: Reggab Khalid 
Published: January 2024

Abstract
In this present work, the Nikiforov-Uvarov functional analysis is suggested to determine the solutions of the Schrodinger equation supported by different types of potentials and employing the Greene-Aldrich approximation. The objective was to estimate the energy spectrum of some diatomic molecules (CO, NO, N2, CH) by resolving the Schrodinger equation with the collective potential model (modified Kratzer potential plus Yukawa potential). As we compared our eigenvalue outcomes with other numerical results that were acquired by other researchers for the specific case of modified Kratzer potential, we observed that this method produced satisfactory results. The present approach may be applied to similar problems in the literature.

Published: January 2024

Abstract
The CNO cycle is the main source of energy in stars more massive than our Sun. This process defines the energy production, the duration of which can be used to determine the lifetime of massive stars. The cycle is an important tool for determining the age of globular clusters. Radiative proton capture via

, at energies of astrophysical interest, is an important process in the CNO cycle. In this project, we apply a potential model to describe both non-resonant and resonant reactions in the channels where radiative capture occurs through electric

transitions. We employed the R-matrix method to describe the ongoing reactions via

resonant transitions, when it was not possible to correctly reproduce the experimental data using the potential model. The partial components of the astrophysical S-factor are calculated for all possible electric and magnetic dipole transitions in 15O. The linear extrapolated S-factor at zero energy (S(0)) agrees well with earlier reported values for all transition types considered in this work. Based on the value of the total astrophysical S-factor, depending on the collision energy, we calculate the nuclear reaction rates for

. The computed rates agree well with the results reported in the NACRE II Collaboration and most recent existing measurements.
Reconstructing parton distribution function based on maximum entropy method*

Published: January 2024

Abstract
A new method based on the maximum entropy principle for reconstructing the parton distribution function (PDF) from moments is proposed. Unlike traditional methods, the new method does not require any artificial assumptions. For the case of moments with errors, we introduce Gaussian functions to soften the constraints of moments. Through a series of tests, the effectiveness and reconstruction efficiency of this new method are evaluated comprehensively, demonstrating that this method is reasonable and can achieve high-quality reconstruction with at least the first six moments as input. Finally, we select a set of lattice quantum chromodynamics (QCD) results regarding moments as input and provide reasonable reconstruction results for the pion.
