Published: December 2024

O racismo estrutural impõe muitas barreiras ao povo negro no Brasil, sendo uma delas em relação à alimentação e, consequentemente, à nutrição. Este artigo, portanto, tem como objetivo discutir acerca da fome em uma perspectiva interseccional, bem como apresentar a prática de fortalecimento da saúde mental, física e ancestral dos estudantes universitárias/os negras/os por meio do Ajeum, este sendo um recurso de nutrição na Liga Acadêmica de Relações Étnico-Raciais Sankofa. Assim, o estudo aqui descrito foi desenvolvido a partir de uma pesquisa de abordagem qualitativa de caráter exploratório, amparada metodologicamente em observação participante e embasada epistemologicamente em teorias decoloniais e no conceito de interseccionalidade. Conclui-se por ela que, considerando a fome enquanto ausência nutritiva que impacta tanto a saúde física quanto mental das pessoas negras, pode-se dizer que o Ajeum é um contraponto a isso enquanto “nutrição” de conhecimento e construção de epistemologias, de espaços de acolhimento e de subjetividade do povo negro.

Published: December 2024

Bu çalışma, Türkiye’nin Akdeniz Bölgesi’nde yer alan Mersin ili örneğinde, tarımsal sulama göletlerinin bölgesel iklim, bitki örtüsü ve su kaynakları üzerindeki uzun vadeli etkilerini uydu görüntüleri ve meteorolojik verilerle incelemektedir. Çalışmanın metodolojisi, 1985-2023 yılları arasındaki Landsat uydu verileri ile meteorolojik veri setlerinin entegrasyonuna dayanmaktadır. Arazi sınıflandırması için nesne tabanlı görüntü işleme teknikleri kullanılarak bitki örtüsünün ve su kütlelerinin değişimleri haritalanmış, sınıflandırma doğruluğu hata matrisi ve farklı doğruluk metrikleriyle değerlendirilmiştir. Ayrıca, kuraklık analizinde Standartlaştırılmış Yağış İndeksi kullanılarak Mann-Kendall, Spearman Rho ve Sen Slope gibi trend analiz yöntemleriyle kuraklık eğilimleri incelenmiştir. Sonuçlar, 1985 yılında 51 olan sulama göleti sayısının 2023'te 1935’e çıktığını ve bu artışın NDVI değerlerindeki yükselişle birlikte bitki örtüsünün korunmasına katkı sağladığını ortaya koymaktadır. Kuraklık analizleri, çalışma bölgesinde kurak dönemlerin bitki örtüsüne olan olumsuz etkilerinin sulama göletleri sayesinde azaldığını göstermektedir. Özellikle mikro iklim üzerinde düzenleyici bir etkisi olan bu göletler, yarı kurak bölgelerde tarımsal üretim sürdürülebilirliği için stratejik bir su yönetimi aracı olarak değerlendirilmektedir. Bu bulgular, tarımsal sulama göletlerinin su kaynaklarının sürdürülebilir yönetimi, iklim değişikliği ile mücadele ve çevresel direnci artırma gibi konularda önemli bir potansiyele sahip olduğunu göstermektedir. Bu kapsamda, yarı kurak ve kurak bölgelerde sulama göletlerinin sayısının artırılması ve bu yapıların planlamasında iklim dostu yaklaşımlar benimsenmesi önerilmektedir.

Advantages of G-band radar in multi-frequency liquid-phase microphysical retrievals
Authors: Courtier Benjamin M. , Battaglia Alessandro , Mroz Kamil
Published: December 2024

Abstract. Radar-based microphysical retrievals of cloud and droplet properties are vital for informing model parameterisations of clouds and precipitation, but these retrievals often do not capture the details of small droplets in light rain or drizzle. A state-of-the-art G-band radar is used here to demonstrate improvements to microphysical retrievals in a case study featuring light rain. Compared to W-band radar, improvements are seen in the retrieval of vertical wind speed due to the location of Mie minima at smaller droplet sizes with the G-band radar. This, in turn, has an impact on the retrieval of the drop size distribution, allowing for better accuracy in the retrieval of the characteristic drop diameter and for improvements in the retrieval of the particle number concentrations of small droplet sizes. The dual-Doppler velocity (DDV) between the Ka- and G-bands shows increased dynamic range compared to the Ka–W pairing, particularly for instances presenting small characteristic drop diameters. The increased attenuation experienced at G-band enables improved retrievals of liquid water content and precipitation rate when paired with W-band or Ka-band compared to the W-band and Ka-band pairing. This is particularly noticeable in periods of light rain when the W-band and Ka-band radars receive negligible attenuation, while the attenuation at G-band is much greater.
Source-to-sink pathways of dissolved organic carbon in the river–estuary–ocean continuum: a modeling investigation
Authors: Yao Jialing , Chen Zhi , Ge Jianzhong , Zhang Wenyan
Published: December 2024

Abstract. Transport and cycling of dissolved organic carbon (DOC) are active in estuaries. However, a comprehensive understanding of the sources, sinks, and transformation processes of DOC throughout the river–estuary–ocean continuum is yet to be derived. Taking the Changjiang Estuary and adjacent shelf sea as a case study area, this study applies a physics–biogeochemistry coupled model to investigate DOC cycling in the river–estuary–ocean continuum. DOC is classified into two types depending on the origin, namely terrigenous DOC (tDOC) and marine DOC (mDOC). Simulation results were compared with observations and showed a satisfactory model performance. Our study indicates that in summer, the distribution of DOC in the Changjiang Estuary is driven by both hydrodynamics and biogeochemical processes, while in winter, it is primarily driven by hydrodynamics. The spatial transition from terrigenous-dominated DOC to marine-dominated DOC occurs mainly across the contour line of a salinity of 20 PSU. Additionally, the source–sink patterns in summer and winter are significantly different, and the gradient changes in chlorophyll a indicate the transition between sources and sinks of DOC. A 5-year-averaged budget analysis of the model results indicates that the Changjiang Estuary has the capability to export DOC, with tDOC contributing 31 % and mDOC accounting for 69 %. The larger proportion of mDOC is primarily attributed to local biogeochemical processes. The model offers a novel perspective on the distribution of DOC in the Changjiang Estuary and holds potential for its application in future organic carbon cycling of other estuaries.
Kinematic properties of regions that can involve persistent contrails
Authors: Hofer Sina Maria , Gierens Klaus Martin
Published: December 2024

Abstract. Contrails can last for many hours in the sky if they form in ice supersaturated regions (ISSRs). Contrail formation is possible once the ambient air is sufficiently moist and cold (below -40 °C) such that the water vapour in the exhaust of an aircraft engine transiently becomes water saturated, which initiates formation of droplets which immediately freeze. Contrails are persistent when the ambient relative humidity with respect to ice is at least 100 %. Cirrus clouds and contrails consist of material ice crystals, which move with the wind. Ice supersaturation is an immaterial feature, which does not generally move with the wind. However, the exact movement of ISSRs and how they move in comparison to the winds, is currently unknown. We analyse their relation using data from the German Weather Service. Our results demonstrate the kinematic differences and similarities of the movement of ISSRs in comparison to the motion of the air in and through the ISSRs. We show that the ISSRs on average move slower than the wind at the same location, the direction of movement is usually quite similar and the distributions of both velocities follow Weibull distributions. The almost identical direction of the movements is beneficial for contrail lifetimes, but the contrail lifetime is not generally determined by the lifetime of ISSRs. It happens that contrails are blown out of ISSRs with the wind. We assume that our study can be used as a basis for further analyses of the movement of ISSRs and their movement properties. Furthermore, our method of analysis is applicable to other extended features or areas, for instance for areas where aircraft non-CO2 emissions would have a particularly large climate effect.
Observational partitioning of water and CO2 fluxes at National Ecological Observatory Network (NEON) sites: a 5-year dataset of soil and plant components for spatial and temporal analysis
Authors: Zahn Einara , Bou-Zeid Elie
Published: December 2024

Abstract. Long-term time series of transpiration, evaporation, plant net photosynthesis, and soil respiration are essential for addressing numerous research questions related to ecosystem functioning. However, quantifying these fluxes is challenging due to the lack of reliable and direct measurement techniques, which has left gaps in the understanding of their temporal cycles and spatial variability. To help address this open challenge, we generated a dataset of these four components by implementing five (conventional and novel) approaches to partition total evapotranspiration (ET) and CO2 fluxes into plant and soil fluxes across 47 National Ecological Observatory Network (NEON) sites. The final dataset (https://doi.org/10.5281/zenodo.12191876; Zahn and Bou-Zeid, 2024) spans a 5-year period and covers various ecosystems, including forests, grasslands, and agricultural terrain. This is the first comprehensive dataset covering such a wide spatial and temporal distribution. Overall, we observed good agreement across most methods for ET components, increasing confidence in these estimates. Partitioning of CO2 components, on the other hand, was found to be less robust and more dependent on prior knowledge of water use efficiency. This highlights some limitations of these present methods that we discuss, emphasizing the broader challenge posed by the lack of an accurate reference method to validate against. Despite these limitations, this dataset has several potential applications, especially in addressing critical questions regarding the response of ecosystems to extreme weather events, which are expected to become more severe and frequent with climate change.
Technical Note: Improved volume and derived value calculations for polished zircon
Authors: Peak Barra A.
Published: December 2024

Abstract. Polishing mounted mineral crystals prior to bulk grain (U-Th)/He thermochronology analysis offers many advantages for characterizing and subsampling each grain via in situ methods to obtain the maximum geologically relevant information. However, polishing introduces complications for calculating grain volume, on which many derived (U-Th)/He data partially depend. Impacted data include isotope concentrations, effective uranium (a proxy for radiation damage), and alpha-ejection correction factors (FT) which are used to correct (U-Th)/He dates. These derived data are integral to interpreting (U-Th)/He dates; without a way to accurately calculate these values for polished grains, the benefits of polishing and in situ measurements can be greatly reduced or negated. This reality has resulted in many studies forgoing polishing and thus missing potentially important data. To address this issue, this paper presents a set of equations encoded in an R script to calculate volume and derived values for polished zircon that can be easily integrated into existing workflows for bulk grain (U-Th)/He analysis.
Simulating the effects of sea level rise and soil salinization on adaptation and migration decisions in Mozambique
Authors: Pandey Kushagra , de Bruijn Jens A. , de Moel Hans , Botzen W. J. Wouter , Aerts Jeroen C. J. H.
Published: December 2024

Abstract. Coastal flooding and sea level rise (SLR) will affect farmers in coastal areas, as increasing salinity levels will reduce crop yields, leading to a loss of net annual income for farming communities. In response, farmers can take various actions. To assess such responses under SLR, we applied an agent-based model (ABM) to simulate the adaptation and migration decisions of farmers in coastal Mozambique. The ABM is coupled with a salinization module to simulate the relationship between soil salinity and SLR. The decision rules in the model (DYNAMO-M) are based on the economic theory of subjective expected utility. This theory posits that households can maximize their welfare by deciding whether to (a) stay and face losses from salinization and flooding, (b) stay and adapt (e.g. switching to salt-tolerant crops and enhancing physical resilience such as elevating houses), or (c) migrate to safer inland areas. The results show that coastal farmers in Mozambique face total losses of up to USD 12.5 million yr−1 from salt intrusion and up to USD 1200 million yr−1 from flooding of buildings (RCP8.5 in the year 2080). Sorghum farmers may experience little damage from salt intrusion, while rice farmers may experience losses of up to USD 4000 yr−1. We show that medium-sized farmers (1–5 ha) are most at risk. This is because their farm size means that adaptation costs are substantial, while their incomes are too low to cover these costs. The number of households adapting varies between different districts (15 %–21 %), with salt adaptation being the most common, as costs are lowest. Despite adaptation measures, about 13 %–20 % of the total 350 000 farmers in coastal flood zones will migrate to safer areas under different settings of adaptive behaviour and different climatic and socio-economic scenarios.
Role of the quasi-biennial oscillation in alleviating biases in the semi-annual oscillation
Authors: Jaison Aleena M. , Gray Lesley J. , Osprey Scott M. , Knight Jeff R. , Andrews Martin B.
Published: December 2024

Abstract. Model representations of the stratospheric semi-annual oscillation (SAO) show a common easterly bias, with a weaker westerly phase and stronger easterly phase compared to observations. Previous studies have shown that both resolved and parameterized tropical waves in the upper stratosphere are too weak. These waves propagate vertically through the underlying region dominated by the stratospheric quasi-biennial oscillation (QBO) before reaching the SAO altitudes. The influence of biases in the modelled QBO on the representation of the SAO is therefore explored. Correcting the QBO biases helps to reduce the SAO easterly bias through improved filtering of resolved and parameterized waves that contribute to improving both the westerly and the easterly phases of the SAO. The time-averaged zonal-mean zonal winds at SAO altitudes change by up to 25 % in response to the QBO bias corrections. The annual cycle in the equatorial upper stratosphere is improved as well. Most of the improvements in the SAO occur during the QBO easterly phase, coinciding with the period when the model's QBO exhibits the largest bias. Nevertheless, despite correcting for the QBO bias, there remains a substantial easterly bias in the SAO, suggesting that westerly wave forcing in the upper stratosphere and lower mesosphere is still severely under-represented.

Mathematics of Machine Learning: An Introduction
Authors: Wojtowytsch Stephen
Published: December 2024

Over the course of just a few decades, machine learning has grown into a force which shapes modern life perhaps as much as the combustion engine or wireless communication. As we drive to work, machine learning algorithms extract license plate numbers from images captured by automatic cameras at busy intersections. At work, they measure our productivity and govern our supply chains. In our personal lives, they power product recommendations on online shopping sites and suggestions on social media. In our homes and on our devices, they recognize our voices and our faces. They process our loan applications and evaluate our medical images. More globally, they stabilize power grids and assist in planning flight routes. There is not a space in our public and personal lives which machine learning has not at least begun to affect.
For a field as ubiquitous, it is fairly poorly represented in our common knowledge. This article aims at giving a high level introduction to some core tasks, ideas and methods of machine learning for readers who are familiar with at least some undergraduate mathematics. Advanced readers may get more from certain sections, but our goal is to present a self-contained picture which requires little knowledge beyond calculus in multiple variables and elementary linear algebra. For readers who have not taken many of the advanced classes, this may also motivate why certain fields of study are of interest in applications.
One big omission in this article are deep neural networks, i.e. the models which underly 'deep learning.' Due to their special importance, they will be discussed in a separate companion article.

Forsaking Fortune: Luck and Its Limited Utility to Cancer Diagnosis
Authors: Allen Hannah
Published: December 2024

This paper interrogates the concept of luck in cancer diagnosis. I argue that while it might have some utility for individuals, at the clinical and research level, the concept impedes important prevention efforts and misdirects sources of blame in a cancer diagnosis. Such use, in fact, has the possibility of harming already vulnerable efforts at ameliorating social determinants of health and should therefore be eliminated from research and clinical contexts.
Admissions: A report from a pilgrimage to an alternative university
Authors: Feinstein Sandy , Wang Bryan Shawn , Fay Nicolas , Tam Nathan , Bernhart Nicollas , Ebersole Kyla
Published: December 2024

“Admissions” is a speculative fiction invoking two traditions – science and literature – that reflects on creativity in education. The overarching frame is that of a science report and the literary construct is a pilgrimage, very loosely modelled on the work of Geoffrey Chaucer, as well as on the tales of imagined travel by Sir Francis Bacon (New Atlantis) and Margaret Cavendish, Duchess of Newcastle (The Blazing World). The intent is partly to evoke the critical power in creative work that simultaneously engages the inherent criticality of creative expression across disciplines. More specifically, each voice offers a different “plane” of creativity and learning that together intersect and combine to make a more complete education.

Published: December 2024

Na przestrzeni lat zjawisko mobbingu znalazło duże zainteresowanie zarówno w nauce, jak i w praktyce. Mimo wielu opracowań i licznych badań na temat terroru psychicznego w miejscu pracy, wokół tego zjawiska istnienie wiele niejasności. Problemu dostarczają również używane w przepisach pojęcia nieostre, trudne do jednoznacznej interpretacji. Nie ma jednak wątpliwości, że zjawisko to dotyka zarówno samą ofiarę mobbingu, jak i jej rodzinę. Konsekwencje działań mobbingowych obejmują również zakład pracy osoby mobbingowanej oraz społeczeństwo. Rozwiązaniem takiego stanu rzeczy powinna być polityka antymobbingowa, ale w tym obszarze również istnienie wiele niejasności i niedookreśleń. Obowiązek przeciwdziałania mobbingowi nie polega tylko na działaniach związanych z wystąpieniem zjawiska mobbingu, a więc etapu interwencji i działań naprawczych, ale również działań zapobiegawczych, które powinny być realne i efektywne. Szczególnie ważne w prewencji antymobbingowej jest zaproponowanie adekwatnych do oczekiwań pracowników i pracodawcy, a poprzedzonych wnikliwą diagnozą potrzeb, szkoleń prewencyjnych o tematyce mobbingu.

Published: December 2024

Coal is one of the essential energy sources, found abundantly within the earth's crust. Most coal mines worldwide, particularly in Afghanistan, are extracted using underground mining method. In order to extract coal mines through underground mining, well-reasoned and technical plans that answer all engineering and safety issues must be arranged. Extraction of coal layers underground causes various convulsions in the roof and floor of coal layers. The number of convulsions and its functioning depends on a series of different geological and technical factors. Therefore, in this research, the effective factors on how mine pressure works during underground coal mining have been researched and investigated using the library method, and later 16 effective factors have been selected for the occurrence of mine pressure. In order to determine the effect of these factors on how mine pressure works, a questionnaire was prepared and distributed to 32 university professors and professional engineers engaged in engineering in the mining sector. The results of these questionnaires show that all the selected factors have an important effect on the performance of mine pressure, including the type of roof rock, the direction of the sealing systems and the nature of the extraction pits have a great effect on the performance of the mine pressure during the underground extraction of coal mines.

Study of the Potential of the Active Compounds of Moringa oleifera Leaves in Increasing the Intake of Fe+3 in Pregnant women through Docking and Molecular Dynamics Methods on the Enzyme “Human Duodenal Cytochrome B” (Dcytb)
Authors: Halimatussakdiah Halimatussakdiah , Rahmawati Rachmawati , Zakiah Noni , Frengki Frengki
Published: December 2024

Iron supplements in pregnant women are often combined with ascorbic acid. The electron donor ascorbic acid plays an essential role in reducing Fe+3 ions to Fe+2 so that they are easily absorbed through the DMT1 channel of human duodenal enterocyte cells. The electron transfer mechanism of ascorbic acid also allows other compounds rich in hydroxyl groups to play a role, such as compounds belonging to the phenolic-flavonoid group. The Moringa oleifera plant, apart from being known to be rich in nutrients such as ascorbic acid and high concentrations of Fe+3, also contains various secondary metabolites such as compounds belonging to the phenol-flavonoid group, alkaloids, steroids, glucosinolates, and fatty acids. This study attempted to screen 50 bioactive compounds contained in the leaves of the Moringa oleifera plant as reducing agents for Fe+3 to Fe+2 ions through the enzyme of “Human Duodenal Cytochrome B” (Dcytb). The crystal structure (3D) of the Dcytb enzyme was obtained from a web server https://www.rcsb.org/ (Pdb. id 5ZLG). Meanwhile, the 3D structures of 50 compounds from Moringa oleifera were downloaded in “SMILES” format from PubChem and converted to 3D format using the “MOE Builder tool”. The research method used molecular and dynamic molecular docking techniques through “MOE 10. 2008” software. The results of molecular docking of the Dcytb enzyme obtained 19 ligand compounds with stronger ∆Gbinding values than the ascorbic acid as control ligands. The strongest affinities were shown by Quercetin-3-O-glucoside with a ∆Gbinding value of -23.10 kcal/mol, Kaempferol-3-O-glucoside with a ∆Gbinding value of -18.99 kcal/mol, Rutin with a ∆Gbinding value -18.07 kcal/mol, Vicenin-2 with a ∆Gbinding value of -17.31 kcal/mol, etc. In comparison, Ascorbic acid control has an affinity with a ∆Gbinding value of -13.29 kcal/mol. All of the tested phenolic-flavonoid compounds except genistein have a hydroxyl group with a strong affinity for the Dcytb enzyme, interacting in the "pocket" region of the enzyme to form hydrogen bonds with Lys 79, Lys 83, and Arg 152. The results of the molecular dynamics simulation of glucoconringin, kaempferol-3-O-glucoside have a strong interaction and is better stable than ascorbic acid at its binding site, while epicatechin has a stability pattern similar to that of ascorbic acid observed in 2000 pc of molecular dynamics simulations. These characteristics allow Moringa oleifera to be rich in compounds that have the potential to activate the Dcytb enzyme.
Optimizing Energy-Efficient Machine Learning Algorithms for Real-Time Attack Detection in IoT Devices
Authors: Vishal Gotarane
Published: December 2024

Energy efficiency is a critical challenge in the expanding domain of In-ternet of Things (IoT) networks, where resource-constrained devices must operate securely under strict energy limitations. This study explores the application of Levy-Based Moth-Flame Optimization (LB-MFO) to enhance intrusion detection in IoT systems. Using the CICIDS 2017 dataset, LB-MFO was evaluated against standard machine learning models, including Logistic Regression, Decision Trees, Random Forest, and Support Vector Machines. To further optimize energy usage, techniques such as pruning, quantization, and model compression were employed. The results demonstrate that LB-MFO consistently outperformed other models, achieving 96% accuracy with a performance score of 0.98 while consuming only 0.018–0.020 W with minimal latency of 14–15 ms under optimization. These findings highlight LB-MFO’s potential to deliver accurate and energy-efficient intrusion detection, making it ideal for real-time IoT applications.

Quality control in solar cell production relies on characterization methods that are fast enough to yield information on the properties of each solar cell in less than about one second. Imaging techniques such as electroluminescence (EL) are well established methods revealing spatially resolved quality mappings. Scanning techniques such as light beam induced current (LBIC) are common laboratory methods yielding complementary information but do not meet the speed requirements. In our work, we analyse an inline implementation of the LBIC method which is extended with respect to its measurement parameters, i.e., both the laser power and a solar cell bias-voltage are varied. As these extended conditions differ from conventional LBIC-applications at zero bias and low injection, we compare our inline-LBIC images with EL images and conventional LBIC images by means of an image contrast analysis. We find that our method resembles more the EL imaging as variations in the local series resistance are prominently detected. Thus, the proposed LBIC approach with extended measurement parameter range can yield both local short circuit information and local series resistance information. With our setup, measurement speeds around 700 ms are achieved.

Published: December 2024

We investigate the barrier properties of phosphorus-doped Si-rich silicon carbide (SixCy) thin films deposited by PECVD against Al/Si alloying in the context of poly-Si/SiOx passivating contacts. The stability of the implied open circuit voltage (iVOC) after firing of single-sided, full area screen-printed Al-contacts increases with carbon content of the barrier layer and depends on the crystallization scheme applied to the samples. Crystallized SixCy layers with an atomic C concentration of about 20 at.% deposited on pre-crystallized poly-Si predominantly show no significant decrease in iVOC values for peak firing temperatures up to 725°C.
RF-Sputtered Ti-Based Dielectric Layers as Al-Diffusion Barrier for Passivating Contacts
Authors: Gapp Benjamin , Plagwitz Heiko , Hahn Giso , Terheiden Barbara
Published: December 2024

We investigate TiNx layers deposited via RF magnetron sputtering on their efficacy as a diffusion barrier layer between Al and tunnel oxide passivated contact layer stacks during contact formation in a fast firing process. We obtain implied open-circuit voltage (iVOC) from photo-conductance decay measurements in order to analyse the diffusion barrier quality for different parameter variations. In particular, we show the impact of both higher peak temperature and increased thermal budget (by decreasing the slope of the temperature ramp) on iVoc during the sintering (“fast firing”) process, leading to passivation quality losses. iVOC losses below 1.5% are shown for peak firing temperatures up to 725°C, with absolute values up to 717 mV after firing. Contact formation at this temperature yields median contact resistivity (ρc) values below 3 mΩcm2 with a sheet resistance (Rsheet) of about 40 Ω/□ for the Ti-based layers.
Cristobalite Formation in Fused Quartz Crucibles for Czochralski Silicon Production in Different Conditions

Published: December 2024

Cristobalite is one of the quartz crystalline polymorphs that forms at above 1470 °C in its pure form and above 1000 °C for quartz glass. Its formation during the Czochralski process is therefore inevitable, and is usually controlled by doping the quartz sand with barium or barium-based coatings. The formation of cristobalite can lead to significant structural defects in silicon ingots. In this work, we studied the influence of various materials (graphite, silicon carbide and alumina) on the formation and properties of the cristobalite layer. In our study we investigated glass samples extracted from a commercially produced fused quartz crucible. The samples were heat-treated in different furnaces with different contact materials: alumina, silicon carbide and graphite. The furnace with alumina as contact material was an open-air furnace, while the two others were purged with argon. All of the heat treatment experiments lasted for 3 hours at a temperature of 1500 °C, which is the approximate temperature of the Czochralski process. After the heat treatment, the samples were investigated by light microscopy and X-ray diffraction. The results showed that the contact material is the most determining factor for the cristobalite layer’s thickness and morphology. The enhancement of cristobalite formation is the greatest by using graphite as the contact material, followed by alumina. Results indicate a retardation in phase transformation in comparison to other materials. These findings are an important step to further understanding of the cristobalite formation kinetics in fused quartz crucibles during the Czochralski process.

This work focuses on reducing In-based TCO thicknesses to their minimum in SHJ solar cells with the goal to demonstrate the possibility of a drastic reduction of indium consumption in the fabrication process. On the front side, the reduction of the ITO thickness down to 15 nm implies to deposit an additional anti-reflective layer. Three anti-reflective dielectric layers have been studied (SiNx, SiOx and a bilayer SiNx/SiOx) in solar cell and module configurations to maximize the performances and evaluate the module stability under UV exposure. Lower Jsc losses after 120 kWh of UV exposure are measured with the use of thinner ITO layers, in agreement with a lower EQE deterioration in the IR range. The use of SiNx dielectric results in the highest stability under UV and to the best performances after 120 kWh. Following further optimizations of the dielectrics and TCO, the 15 nm of ITO/SiNx option was combined with a thin IMO:H TCO on the rear side. TCO thicknesses down to 30 nm were studied on the rear side resulting in overall indium reduction of 77.2% with very limited efficiency loss at the cell level (below 0.1% absolute after light-soaking). Module reliability of these very low indium content solar cells was studied under UV and damp heat treatments highlighting lower degradations than reference cells for UV and promising results after damp heat test.

Published: December 2024

An accurate description of the distribution of hydrogen at solar cell interfaces is critical for understanding both passivation and degradation phenomena. Time-of-flight elastic recoil detection analysis (ToF-ERDA) has recently been employed to study this hydrogen distribution by providing a one-dimensional (1D) depth profile. In this work, ToF-ERDA was used to investigate the hydrogen profile in a SiOX / SiNX passivating stack. The ability to resolve the interface with the c-Si interface was studied by using polished wafers and thin (20 nm) passivating stacks. This approach, coupled with Monte Carlo ERD (MCERD) modelling, showed that the identification of the interfacial oxide was much more clearly defined compared with previous reports using ToF-ERDA. Annealing the SiOX / SiNX at 450 °C for 5 minutes substantially increased the effective lifetime. However, no noticeable change in the H distribution measured with ToF-ERD was observed. We comment on the difficulty of correlating physical hydrogen measurements with the surface recombination properties.

Digital Transformation and Its Impact on Arabic Language Evolution in Social Media
Authors: Arak Mahmoud Hammoud
Published: December 2024

This research paper explores the impact of digital transformation on the evolution of the Arabic language, focusing on how social media platforms have reshaped linguistic practices. Through a combination of qualitative and quantitative methods, including content analysis of social media posts, interviews, and surveys, this study examines the rise of new linguistic forms such as Arabizi (Arabic written in Latin script), code-switching between Arabic and English, and the increasing dominance of regional dialects over Modern Standard Arabic (MSA) in informal communication. The findings indicate that while social media fosters linguistic innovation and adaptability, it also raises concerns about the potential erosion of formal Arabic language skills, particularly among younger generations. Additionally, the study highlights how hybridization of dialects and the use of visual elements like emojis contribute to a dynamic, evolving linguistic landscape. This paper discusses the broader sociocultural implications of these changes, emphasizing the tension between linguistic preservation and modernization in the Arab-speaking world. It concludes with recommendations for future research on the long-term effects of digital transformation on Arabic language education and cultural identity.

Published: December 2024

Small and medium enterprises (SMEs) often struggle to efficiently manage sales transactions and inventory due to a lack of affordable, real-time technological solutions. Existing systems typically fail to offer seamless synchronization and proactive inventory management, which are crucial for resource-constrained businesses. This study addresses these challenges by developing a Mobile Point of Sale (mPOS) application integrated with Firebase, aimed at improving operational performance, reducing data inconsistencies, and supporting decision-making through real-time synchronization. The application was developed using a descriptive research approach, React Native for cross-platform compatibility, and Firebase for its real-time database features. Notable innovations include an automated low-stock notification system and an intuitive user interface for both staff and administrators, designed to streamline inventory management. Comprehensive testing and validation confirmed the system’s reliability, usability, and data consistency. However, the study was limited by its small-scale implementation and the absence of real-world retail trials. Future research should focus on its scalability, integration with advanced analytics, and application in larger retail settings.
