Context. The metal mass fraction of the Sun Z is a key constraint in solar modelling, but its value is still under debate. The standard solar chemical composition of the late 2000s has the ratio of metals to hydrogen as Z/X = 0.0181, and there was a small increase to 0.0187 in 2021, as inferred from 3D non-LTE spectroscopy. However, more recent work on a horizontally and temporally averaged ⟨3D⟩ model claim Z/X = 0.0225, which is consistent with the high values based on 1D LTE spectroscopy from 25 years ago.
Aims. We aim to determine a precise and robust value of the solar metal mass fraction from helioseismic inversions, thus providing independent constraints from spectroscopic methods.
Methods. We devised a detailed seismic reconstruction technique of the solar envelope, combining multiple inversions and equations of state in order to accurately and precisely determine the metal mass fraction value.
Results. We show that a low value of the solar metal mass fraction corresponding to Z/X = 0.0187 is favoured by helioseismic constraints and that a higher metal mass fraction corresponding to Z/X = 0.0225 is strongly rejected by helioseismic data.
Conclusions. We conclude that direct measurement of the metal mass fraction in the solar envelope favours a low metallicity, in line with the 3D non-LTE spectroscopic determination of 2021. A high metal mass fraction, as measured using a ⟨3D⟩ model in 2022, is disfavoured by helioseismology for all modern equations of state used to model the solar convective envelope.

Quantifying Treatment - Outcome in Maxillo-Facial Injuries
Authors: Agarwal Anil , Chari P S , Mitra S 
Published: October 2023

SummaryStatements regarding outcome in Plastic Surgery are often subjective and lack reproducibility, mainly because of lack of quantification of aesthetic issues. A method is being presented using maxillo-facial injuries as a prototype, to resolve virtually any plastic surgical problem into 3 basic components – Function, Aesthetics and Psycho-social. Unfavourable results are graded according to a strictly defined protocol. Aesthetic evaluation is performed by the patient and relatives/friends in a manner designed to reduce subjectivity and physician-induced bias.The system provides a comprehensive patient-satisfaction index which has been found useful for everyday post-surgical assessment and computer-based data-recording. It allows us to quantify results, pin point shortcomings and foster a desirable doctor-patient relationship.With the use of such a system it should be possible to document, compare and even predict treatment-outcomes with a degree of precision not previously achieved.

Published: October 2023

In this work, p-type cuprous oxide (Cu2O) films grown on beta gallium oxide (β-Ga2O3) substrates by magnetron sputtering were reported. The resulting vertical Cu2O/β-Ga2O3 heterojunction p–n diodes demonstrated superior performance compared to devices fabricated with polycrystalline Cu2O thin films. Meanwhile, analysis of the discrepancies between the built-in potential and turn-on voltage revealed diverse carrier transport mechanisms in the fabricated devices. Numerical fitting of the forward J–V characteristics further discerned that distinct carrier transport mechanisms dominated under various bias voltages or temperature conditions. At 300 K, trap-assisted tunneling dominates the regime because of the presence of defects in β-Ga2O3 or Cu2O. While the bias voltage is low, the polycrystalline nature of the films formed at room temperature leads to the prevalence of grain boundaries as the primary source of interface-type defects at the Cu2O/β-Ga2O3 interface. Consequently, the dominant mechanism governing carrier transport is interface recombination. As the temperature increases, however, thermionic emission becomes more important. This study presents an opportunity for further investigation into the epitaxial growth of Cu2O and provides insights into the carrier transport mechanism of β-Ga2O3-based heterojunctions.
Anharmonic effect on the vibrational properties of pristine and Co-doped β-FeSi2 semiconductors

Published: October 2023

The strength of the phonon anharmonic effect of the pristine FeSi2 and Co-doped Fe0.94Co0.06Si2 is investigated by a Raman scattering study on the vibrational properties of those materials in the temperature range of 300–1523 K. All the vibrational modes exhibit significant redshifts with increasing temperature, and their spectral widths increase simultaneously. The structure transition from the semiconducting β phase to the metallic α phase is evidenced by the sudden disappearance of the vibrational modes. The extended Klemens model is applied to study the anharmonic effect on the phonon frequency shift and damping constant, and the four-phonon decaying process is expected to be the dominant one after doping the metal Co. Such an enhancement is also suggested contributing to the reduction of the thermal conductivity in Fe0.94Co0.06Si2. In addition, the vibrational properties of the mode at 250 cm−1 are more sensitive to the anharmonicity effect than that of the mode at 195 cm−1. This work provides valuable insights for understanding the high-order anharmonic effects in thermoelectric materials, especially in chemically doped materials.

Published: October 2023

Background Airtankers are able to drop volumes of liquid (suppressant or fire retardant) varying from less than 1 m3 to several tens of cubic metres directly on a fire or with the objective to form barriers of retardant to stop or reduce fire propagation. Aims The objective of this work is to demonstrate that Computational Fluid Dynamics can be used to provide a deep understanding of liquid fragmentation and dispersion when liquid is dropped from an aircraft. Methods A numerical investigation based on the Volume of Fluid method is used for the analysis of airtanker performance and applied here to the biggest airtankers used in Europe: the Canadair CL-415 and Dash-8. Key results Numerical simulations are used to provide an accurate description of tank discharge as well as to study liquid ejection, fragmentation and atomisation in air. From the results, the vertical penetration and lateral expansion of the liquid are described using simple modelling. Conclusions From the numerical simulation, the main characteristics of liquid atomisation and dispersion in air are described and modelled. Implications Computational Fluid Dynamics is an efficient tool that may help to optimise airtanker performance.
The image schemas of container and source-path-goal in the theory of psychodynamic defense mechanisms
Authors: Farhoudi Fateme , Tay Dennis 
Published: October 2023

Abstract
In this article, we evaluated the theory of defense mechanisms from the cognitive linguistics perspective. We chose two basic image schemas of container and path-goal and reviewed three psychodynamic psychotherapy textbooks and two psychology dictionaries to extract passages defining defense mechanisms by one of the selected image schemas. Seventeen defense mechanisms were extracted, categorized, and discussed according to their underlying image schemas. In conclusion, we suggest that the development of the defense mechanisms could be traced back to the early interactions of an infant with the physical environment. Moreover, there might be a relationship between the adaptive levels of the defense mechanisms and the chronological development of image schemas in an infant’s mind, e.g., defenses defined using the image schema of container are usually less adaptive than defenses defined using the image schema of path-goal.
Russian equivalents of the English over
Authors: Kalyuga Marika 
Published: October 2023

Abstract
The article deals with a comparative analysis of the English over and the Russian language items
that serve as its approximate translation equivalents. The main attention is on such Russian equivalents of over
as the prepositional phrases nad with the instrumental case, čerez with the accusative case,
za with the accusative case and po with the dative case, as well as the prefixes
pere- and pro-. The research is undertaken using the Cognitive linguistic framework or, more
precisely, the theory of conceptual metaphor. The aim of the article is to analyse the Russian language means of coding the
spatial relations that are similar to those expressed by the English over and to trace patterns of extension of
spatial meanings into non-spatial domains in these languages. The study reveals that although English is an analytic language and
Russian is a synthetic (fusional) language and, therefore, they use different means to express meanings, similar
conceptual-metaphorical motivations of semantic extensions can be traced in both languages.
Translating figurative language
Authors: Denroche Charles 
Published: October 2023

AbstractThis article brings together the extensive literature on figurative language and translation into a single framework to serve translators in a directly practical way in their practice/training. It encourages a view of figurativeness as the norm rather than the exception and figurative language as a flexible meaning-making resource rather than an obstacle to contend with. All language is characterized as figurative because of the indeterminacy of language and the partial nature of meaning making; all translation is viewed as non-literal because of the lack of exact correspondences between languages and the need to use near equivalents. Two approaches are recommended: (1) recreating the ‘semantic space’ of the source rather than mechanically matching its lexicogrammar; (2) viewing metonymy and metaphor as ‘master tropes’ and translating other tropes in terms of relatedness. The challenges of translating metonymy and metaphor in discourse at the level of the whole text are also explored.
Influencing mechanisms of weld root tip on microstructure and mechanical properties of electron beam welded joints of titanium alloy thick plates

Published: October 2023

The welding of titanium alloy thick plates often formed a narrow weld seam in the weld root, named as ‘weld root tip’, because of insufficient fusion, which could reduce the joint properties. In this study, 30 mm-thick Ti-5Al-5Mo-5V-1Cr-1Fe alloy was butt welded via electron beam welding to reveal the influencing mechanisms of the weld root tip on joint microstructure and mechanical properties. The subparallel or parallel weld seam with the weld angles of 0°–3° between the centre line and edge of the fusion zone removed the weld root tip, achieving almost the same mechanical properties with those of the welding zone.
New analytical results in solid state physics using the Lambert W function
Authors: Houari Ahmed 
Published: October 2023

Abstract
Analytical solutions in physics are always preferred for the sake of mathematical completeness. For this, using the Lambert W function, I derive closed-form analytical expressions for the equilibrium interionic distance in an ionic crystal, the formation energy of a vacancy in a crystal, the zero-temperature energy gap of a clean-limit superconductor and the critical Kosterlitz–Thouless temperature for the phase transition in 2D-XY model. Besides their theoretical interest, some of the present results suggest alternative experimental determinations of the relevant physical quantities. In addition, I similarly derive an explicit analytical formula based on the Lambert W function for a determination of the Boltzmann constant. This formula is proposed here as a theoretical basis for an experimental method to measure this constant. This method is suitable for undergraduate physics students.
Unraveling the CMB lack-of-correlation anomaly with the cosmological gravitational wave background
Authors: Galloni Giacomo , Ballardini Mario , Bartolo Nicola , Gruppuso Alessandro , Pagano Luca , Ricciardone Angelo 
Published: October 2023

AbstractSince the very first observations, the Cosmic Microwave Background (CMB) has revealed on large-scales unexpected features known as anomalies, which challenge the standard Λ cold dark matter (ΛCDM) cosmological model. One such anomaly is the “lack-of-correlation”, where the measured two-point angular correlation function of CMB temperature anisotropies is compatible with zero, differently from the predictions of the standard model. This anomaly could indicate a deviation from the standard model, unknown systematics, or simply a rare realization of the model itself. In this study, we explore the possibility that the lack-of-correlation anomaly is a consequence of living in a rare realization of the standard model, by leveraging the potential information provided by the cosmological gravitational wave background (CGWB) detectable by future gravitational wave (GW) interferometers. We analyze both constrained and unconstrained realizations of the CGWB to investigate the extent of information that GWs can offer. To quantify the impact of the CGWB on the lack-of-correlation anomaly, we employ established estimators and introduce a new estimator that addresses the “look-elsewhere” effect. Additionally, we consider three different maximum multipoles, denoted asℓmax, to account for the anticipated capabilities of future GW detectors (ℓmax= 4, 6, 10). Summarizing our findings for the case ofℓmax= 4, we identify the angular range [63∘- 180∘] as the region where future observations of the CGWB maximize the probability of rejecting the standard model. Furthermore, we calculate the expected significance of this observation, demonstrating that 98.81% (81.67%) of the constrained GW realizations enhance the current significance of the anomaly when considering the full-sky (masked)PlanckSMICA map as our CMB sky.

Published: October 2023

Abstract
This paper proposes power generation from footsteps using piezo electronic sensors. The major issue our country is facing is adequate power generation and its distribution to households and industries. Nowadays numerous power resources are present both in non-renewable and renewable forms, but still, it is not sufficient to meet the power requirements. This paper exploits the human population as one of the resources and power generation is done from the walking or running activities of human beings and using the piezoelectric effect. The generated power is then stored and utilized for driving small power devices. This method is very effective when installed at places where people’s movement is dense.

Authors: Chandrasekhar Rao J , Srinivasa Rao U , Vinod Kumar M , Sreenivasa Rao D 
Published: October 2023

Abstract
This research proposes a compact dual-band patch antenna for 5G mmWave wireless communication applications. The 5 × 4.8 × 0.508 mm3 sized antenna is made of Rogers RT/duroid 5880(tm) dielectric material and is fed via a 50-Ω microstrip feedline. A rectangular slot was used on the radiating patch to create resonance at the 30GHz band from 29.2GHz to 31GHz. Another slot was etched from the ground to obtain another resonance at 49GHz from 48GHz to 50.1GHz. The S11 of -10dB and VSWR of less than 2 indicates that the designed bands have strong impedance matching capabilities. Peak gain of 4.99 dBi at 30GHz and 7.39 dBi at 49GHz are attained, as well as maximum radiation efficiency of more than 90% and sustained omnidirectional radiation characteristics are achieved. The results demonstrate that the suggested antenna is appropriate for next-generation wireless applications.

Identification of the distribution and characteristics of local sago from Kendari, Southeast Sulawesi
Authors: Yusuf D N , Leomo S , Rakian T C , Sutariati G A K , Rahni N M , Samai S 
Published: October 2023

Abstract
In eastern Indonesia, particularly Southeast Sulawesi, sago is an important commodity as a carbohydrate-producing plant. Carbohydrate output can reach 15-24 tons ha-1 annually, surpassing rice, corn, and wheat. Southeast Sulawesi, notably the Kendari mainland, relied on sago starch until rice became the predominant carbohydrate source. Sago starch, like other basic starches, has no taste. Sago does not contain fat or protein, so it must be eaten alongside other local foods that do. Sago palms grown naturally produce 2–5 tons of dry starch per hectare. With 500 sago clumps per acre of varied ages, 100 trees might be harvested annually. Well-maintained farms can generate 150 kg of starch palm and 15 tons ha−1. Currently, only 5,912 ha are planted with sago, from the total area in 1985 was 13,000 ha. Sago development requires characterizing and identifying Kendari Southeast Sulawesi’s local sago. The results showed that there were three dominant types of local sago in Kendari, namely sago molat, sago tuni and sago borowila, originating from the main sago production centres in Kendari such as in Tobimeita, Abeli and Pohara.

Abstract
Elephant foot yam plants have the potential to be developed in Indonesia, planting material has an important role in the propagation and reproduction of elephant foot yam. The selection of the right organic fertilizer raw materials will have a positive effect on the growth and production of the growth of elephant foot yam plants and the environment. The research was conducted on Research Land of Centre for Roots and Tuber Study, Faculty of Agriculture Universitas Sumatera Utara and implemented August 2021 - January 2022. The study used a randomized block design with two factors. This study aims to determine the effect of the two planting materials (bulbil and tuber) and 3 types of organic fertilizer (chicken manure, goat manure, cow manure and without organic fertilize) on the growth of elephant foot yam. The results of this experiment showed that planting material had a significant effect on height of first shoot, number of leaves, and tuber weight but had no significant effect on number of bulbils. All observed parameters increased significantly with the addition of organic fertilizers. The treatment that gave the best elephant foot yam plants growth results was bulbil as a planting material and the application of chicken manure.
