Published: October 2023

Background Custom-compounded subcutaneous implants are being used widely in Australia for gender-affirming hormone therapy. However, there is no published literature regarding their use for this purpose. Methods Electronic medical records were audited for consecutive clients who received oestradiol implants April 2019–November 2022 in gender clinics held within Hunter New England Health District in New South Wales, Australia. Serum oestradiol levels were analysed for implant doses 50–200 mg, and predicted oestradiol level was modelled following 100 mg implant insertion. An electronic consumer survey was sent to a convenience sample of implant recipients. Results A total of 38 clients received 88 implants, with 100 mg oestradiol implants being the most frequently used (68%). The median interval between insertion procedures was 270 (IQR 186–399) days. The median serum oestradiol levels following implant insertion, for all implants combined, were within the target range of 250–600 pmol/L at 1-, 3-, 6-, 9- and 12-month time points. Following insertion of a 100 mg implant, the estimated time to reach a predicted serum oestradiol of ≤250 pmol/L was 4 months after an initial implant, and 13 months after subsequent implants. Seventeen consumer surveys were received from 28 invitations. All respondents had previous experience of oral and/or transdermal oestradiol use. Oestradiol implants were preferred due to ease of use, perceived effectiveness, and the belief that other methods were less safe or associated with intolerance and side effects. Conclusions Oestradiol implants are effective in achieving target serum oestradiol levels over a sustained period. Further research with larger cohorts could identify the optimal dosage regimen.
Early Phases of Star Formation: Testing Chemical Tools
Authors: Martinez N. C. , Paron S. 
Published: October 2023

Abstract
Star-forming processes strongly influence the ISM chemistry. Nowadays, many high-quality databases are available at millimeter wavelengths. Using them, it is possible to carry out studies that review and deepen previous results. If these studies involve large samples of sources, it is preferred to use direct tools to study the molecular gas. With the aim of testing these tools such as the use of the HCN/HNC ratio as a thermometer, and the use of H13CO+, HC3N, N2H+ and C2H as “chemical clocks,” we present a molecular line study toward 55 sources representing massive young stellar objects at different evolutionary stages: infrared dark clouds (IRDCs), high-mass protostellar objects (HMPOs), hot molecular cores (HMCs) and ultracompact H ii regions. We found that the use of the HCN/HNC ratio as a universal thermometer in the ISM should be taken with care because the HCN optical depth is a big issue that can affect the method. Hence, this tool should be utilized only after a careful analysis of the HCN spectrum, checking that no line, neither the main nor the hyperfine ones, presents absorption features. We point out that the analysis of the emission of H13CO+, HC3N, N2H+ and C2H could be useful to trace and distinguish regions among IRDCs, HMPOs and HMCs. The molecular line widths of these four species increase from the IRDC to the HMC stage, which can be a consequence of the gas dynamics related to the star-forming processes taking place in the molecular clumps. Our results not only contribute with more statistics, acting as a probe of such chemical tools, useful to obtain information in large samples of sources, but also complement previous works through the analysis of other types of sources.

Published: October 2023

Abstract
This article examines the issue of finding new methodological approaches to the development of problems that can contribute to the preparation of ‘Humanities’ students to pass the state final certification in the format of External independent assessment (EIA). The study analyzes the existing development of methods of qualitative mathematical training of students of humanities classes who study Mathematics according to the basic level program. In particular, the authors of the article were interested in the use of interdisciplinary connections between Mathematics and humanitarian disciplines. The authors of the article identified cross-curricular problems as a means of forming students’ motivation to study Mathematics, as well as a toolkit for measuring their level of readiness to solve typical problems of EIA. The researchers set a goal to develop cross-curricular problems following the EIA program based on the plot of Bulgakov’s novel ‘The Master and Margarita’. An experiment was conducted to confirm the effectiveness of the use of the system of interdisciplinary problems in the preparation for the EIA of humanitarian students. The obtained results confirmed that the implementation of problems in which the intersubject connections of Mathematics and Literature are realized has a more significant effect on both increasing the motivation of students to study Mathematics and their mathematical preparation.

Abstract
The article offers the method of using the online “Creative Thinking through Learning Elementary Maths” and the results of checking the effectiveness of the implementation of this course in the mathematics teacher training system. The research substantiates the possibility of three methodological options for combining educational materials of the online course with the study of the educational discipline “Elementary Mathematics”. The methodological options are chosen depending on the number of credits assigned to the study of the elementary mathematics course at the university. Practical tasks of the course were focused on the organization of students’ activities (recognition, classification, solving and creation) with Rich tasks of three levels of complexity. The results of control tests in Elementary Mathematics give grounds for concluding about the effectiveness of the developed method.

Authors: Samson E C , Plaza C B , Patero J L 
Published: October 2023

Abstract
This study focuses on the development and assessment of an instructional tool known as the “Physics Alphabet Model” for Grade 10 students at Cantilan National High School. The research employs a descriptive design and post-test scores to measure the tool’s effectiveness. Each group, consisting of 30 students, is divided into a control group and an experimental group, where the experimental group is exposed to the Physics Alphabet Model as an instructional aid. The teaching method employed for both groups is the Conventional Method, and the integration of the Physics Alphabet Model occurs within the respective classrooms of the participants. After collecting and analyzing the test scores from both groups, it becomes evident that there is a notable improvement in mean scores between the pre-test and post-test assessments for both methods. Statistical analysis, specifically the T-test, indicates a significant difference when comparing the means of pre-test and post-test scores for both the control and experimental groups. Furthermore, it is noteworthy that the post-test mean score and the associated significance value obtained when integrating the Physics Alphabet Model are significantly higher than those achieved through the Conventional Method alone. Consequently, this study concludes that the incorporation of the Physics Alphabet Model as an instructional resource in the study of physics leads to a substantial enhancement in students’ mean achievement scores.

Published: October 2023

Abstract
A spectroscope is an optical device that can stimulate student’s interest in the visible light’s constituent colors. This educational tool is conventionally used to qualitatively observe the emission spectra of various light sources, which can serve as a springboard to understanding the fundamentals of spectroscopy, the wave nature of light, and the orbital theory of atoms and molecules. This research builds on the functionality and accessibility of a simple spectroscope through the utilization of low-cost readily available materials, and more importantly, improvisation via the inclusion of a magnetic sheet mounted on the entrance slit cover. The magnetic sheet was employed to vary the slit width, to add absorption filters, and to mount a cuvette containing liquid samples. Furthermore, this sheet allowed the simultaneous observation of the emission spectrum of a light source and the transmission or absorption spectrum of the samples. The breadth of data from a variety of activities involving spectra was also made possible by a mobile phone camera as a recording device. In this study, the novel features strengthen the interconnectedness of various concepts in introductory spectroscopy. This elucidates the experimental and theoretical base of STEM Education in domains such as optics and photonics, and molecular spectroscopy.

Published: October 2023

Abstract
The article addresses the relevant issue of today – digitalization of geographic higher education. The future of geographic education in the digital world depends on the use of digital technologies, which are dramatically changing approaches to teaching geography. The generalization of scientific literature and the analysis of pedagogical experience allow the authors to define the concept digitalization of geographic. The article explores some challenges in the implementation of digital technologies in geographic disciplines in higher education: narrowing geographic education digitalization to the use of various gadgets; the application of general purpose digital technologies; underestimation of GIS technologies during the study of geography; occasional use of VR, AR technologies and mobile applications of geographic and cartographic content; the lack of educational and methodological support and proper technological availability. The authors pay special attention to the prospects for the development of geographic education digitalization, which are envisioned in the introduction of “Digitalization of geographic education” into the curriculum of future geography teachers training; the use of high-quality free educational resources (ArcGIS Online, QGIS); the creation of own geo-information platforms (“Digital Geography”); and updating of the material and technical base of the scientific research laboratory on the methodology of teaching geo-information technologies.

Published: October 2023

Abstract
The article, based on the application of anthropological methodology, reveals the phenomenology of the physical-mental interaction between a person and a computer. Ways of integrative use of the concept of Umwelt by J. J. von Uexküll and the theory of movements construction are represented, and Umwelt-oriented strategies for improving computer technologies are presented. The Umwelt, as the world of perception and the world of human activity (in particular, cognitive), can be represented as an anthropo-computer world. On the basis of the current features of the body-mental Umwelt, ways of anthropologically directed improvement of HCI are determined. Using the questionnaire developed by the authors and applying cluster analysis, a survey of students of higher education institutions was conducted in order to determine the physical and mental orientation in Umwelt oriented interaction in the human-computer system. The interpretation of the research results indirectly indicates the systematicity, equality of interaction in the human-computer system. This determines the possibility of distinguishing typical ways of interaction in the human-computer system, among which the bodily and mental-psychological ones are significant, which correspond to certain levels that characterize the systemic, spatio-temporal and structural-functional organization of motor activity in the theory of movements construction.
Substantiation of the sustainable education terms as one of the modern views on STEM education taking to account the European experience
Authors: Shapovalov Y B , Slipukhina I A , Shapovalov V B 
Published: October 2023

AbstractThis paper examines the development of concepts related to education for sustainable development, such as sustainability education, sustainability and education, sustainable education, sustainable development education, sustainable didactics, and sustainable learning. The paper argues that these concepts are insufficient for designing educational processes that fully consider the factors of sustainable development. The paper proposes and justifies the need for new concepts: sustainable pedagogy, sustainable educational process, and didactics for a sustainable educational process. These concepts are based on the components of sustainable development: competence, health, and motivation and socialization. The paper discusses how to use these factors to assess the sustainability of educational approaches. It also provides a practical example of how to apply the “sustainability” methodology in the educational process using Google Lens in biology lessons.

Abstract
The development of energy storage is a necessary support for the realization of the green energy future. At present, battery energy storage stations (BESSs) consume large amounts of energy, the energy loss relationships between various devices in a station are complex, and there is a lack of energy loss analysis and statistical methods for BESSs. It poses challenges to the further development of BESSs in the power grid. To deal with this issue, this paper establishes the energy loss indicators and proposes the energy loss evaluation methods for BESSs. The simulation results verify that the proposed method can accurately reflect the overall energy loss level of the BESSs and the proposed method of energy loss estimation and analysis can support the development of energy saving and loss reduction.

Published: October 2023

Abstract
Compared with mineral oil, plant insulation oil has a higher flash point, excellent natural degradation ability, and higher electrical insulation. It is expected to become the main component of transformer insulation oil, but the fire safety of this oil needs to be further analyzed and improved. In this paper, a cone calorimeter was used to test the combustion of typical plant insulating oil (camellia seed oil, soybean oil) and mineral oil (25# mineral oil) under different radiant heat flows and initial oil thickness. The combustion parameters such as ignition time, heat release rate, and carbon generation rate were measured. The combustion characteristics of 25# mineral oil were greatly affected by radiative heat flow and oil thickness. The peak heat release rate and carbon generation rate of mineral oil under high heat flow (50 kW/m2) were significantly higher than those under low heat flow (25 kW/m2) and increased with the increase of initial oil thickness. Plant insulating oil (camellia seed oil and soybean oil) had similar laws, but the peak value of the heat release rate and carbon generation rate of soybean oil were relatively small. Petrella fire risk assessment method showed that the fire risk ranking in descending order was mineral oil, camellia seed oil, and soybean oil, which provided a reference for the further popularization and application of plant insulation oil transformer.

Abstract
Multicore fiber is regarded as the most efficient way to realize SDM networks. Fabrication of low-loss and low-crosstalk multi-core fiber is the key to achieving high-capacity communication systems. This paper designed and fabricated low transmission loss seven-core single-mode fiber with a standard 125μm cladding diameter based on modified chemical vapor deposition. The preform of MCF is fabricated using drilling method. The seven-core fiber has achieved a low transmission loss of 0.19~0.28dB/km throughout the 1250-1600nm wavelength range. The transmission loss is below 0.19dB/km at 1550nm wavelength. The crosstalk is below -54dB/100km from 1200nm to 1600nm wavelength by utilizing a trench-assisted structure. At 1550nm wavelength, the bending loss (BL) is lower than 0.45dB/m with a bending radius of 5 mm, and the BL is 0.05dB/m with a bending radius of 15 mm. The fabricated multi-core fiber can be used for long-haul transmission and space division multiplexing communication systems.

Published: October 2023

Abstract
A novel approach called DE-ED (Diffractive Encoding-Electronic Decoding) for rapid all-in-focus capturing is presented in this paper. The paradigm combines the strengths of diffractive networks (DON) for encoding and electronic-based networks (ENN) for decoding, resulting in a robust computational imaging framework driven by advanced deep learning techniques. By leveraging the collaboration between diffractive layers and electronic layers, our model achieves remarkable enhancements in the ability to generalize and fit data. This means that the model can effectively capture and process complex visual information, resulting in superior image quality and enhanced performance.

Abstract
With the great progress of hyperspectral imaging technology, airborne hyperspectral cameras have been widely used in the field of earth detection and remote sensing. However, with the increasing resolution of airborne hyperspectral cameras, the amount of data acquired is also growing explosive, The speed and accuracy in the transmission process are easily affected, which poses challenges to the real-time control and data acquisition and storage of airborne hyperspectral cameras. In this paper, a general airborne hyperspectral image acquisition and storage system is designed, which converts the hyperspectral data from the Cameralink interface into a high-speed serial PCIe data stream and realizes high-speed storage of image data. The image width is 2048 pixels, the number of spectral segments is 120, the pixel size is 12bit, and the maximum frame rate is 300 fps. The maximum transmission rate is 2048×120×12bit×300fps, and the data rate is 844Mbps. Based on this, we perform thermal analysis and vibration analysis of the system platform. Experimental results show that the system can achieve stable data transmission and storage, and the data is intact and reliable.
Octastanene Halogenide: A Family of Two-dimensional Nodal Line Semimetals and Topological Insulators
Authors: Zhang Jie 
Published: October 2023

Abstract
With the first principle calculation and k-p model, we find that the Octastanene halogenide is a node line semimetal(NLs) without spin-orbit coupling(soc), forming a fermi ring centered on point G and protected by mirror symmetry. The band simulated by the k-p model fits well with the band calculated by GGA-PBE at point G, and the energy dispersion calculated by the Hamiltonian of the model explains well the formation of node rings. Under the SOC effect, NLs become a two dimensional Topological Insulators(TIs). With the increase of atomic number, the large band gap reaches about 0.16 ev, and the clear spiral edge state of the quantum spin hall effect is obtained. The phonon spectra of the two structures show that they are dynamically stable. These findings provide a new two dimensional material series for the future design and manufacture of NLs and TIs.

Published: October 2023

Abstract
To solve the problem of SVP (Sound velocity profiles) representative error caused by the difficulty of obtaining continuous time series SVP in deep-sea operations, an SVP timing prediction method combining EMD (Empirical mode decomposition) and NARX (Nonlinear autoregressive neural network with external input) is proposed. To begin with, the time-series SVP are stratified according to different depths, and the time-series variation curves of sound velocity at different depths are obtained; Furthermore, the EMD is used to decompose the time series variation curve of sound velocity into multiple IMF (Intrinsic mode function) components, each component contains local characteristic signals of different time scales of the original signal. The NARX is used to establish a prediction model for each IMF components, and the prediction values of the sound velocity at different depths are obtained. The EMD-NARX, NARX and polynomial fitting model are analyzed and verified by Argo buoys data in the South China Sea, and the results of the experiment show that EMD-NARX improves the time series prediction accuracy of sound velocity by 32.24% and 65.15% compared with NARX and polynomial fitting, respectively, so EMD-NARX has a good prediction effect on the time series SVP of the deep sea.

Published: October 2023

Abstract
SBAS-InSAR technology has been widely researched and applied in the large-scale monitoring of mining areas, but due to the influence of spatial and temporal discorrelation, atmospheric delay and noise on the deformation results, as well as the requirements on image quantity, quality and spatial continuity, the SBAS-InSAR technology inferior to the levelling monitoring results in terms of measurement accuracy and reliability. Taking the Yuncheng coal mine as the research area, and after using SBAS InSAR to monitor the subsidence, the levelling monitoring data was used as the constraint to construct the subsidence error surface by polynomial surface fitting, and then the SBAS-InSAR subsidence monitoring results were be corrected. The experimental results show that the settlement difference is better than ±50mm/a, which effectively improves the overall accuracy of SBAS-InSAR settlement monitoring. The experimental results verify the feasibility and effectiveness of using the level monitoring results to correct the deformation monitoring results of SBAS InSAR, and provide effective reference information for improving the accuracy of the deformation monitoring results by multi-source fusion processing.
