Da internet para a sala de aula: percepções de professores em formação inicial em química e física sobre o internetês
Authors: Botelho Daniele Campos , Prata-Linhares Martha Maria 
Published: November 2023

Este trabalho buscou conhecer como professores em formação inicial nos cursos de licenciatura em Química e em Física percebem as práticas linguísticas de seus alunos, especialmente aquelas materializadas na escrita escolar, quando estas apresentam características dos contextos digitais de comunicação, configurando o dialeto internetês. Tomamos por internetês a variante escrita da língua advinda das práticas sociocomunicativas em contextos digitais cuja particularidade mostra-se em características como abreviações de palavras, supressão de letras por motivações fonéticas e inserção de símbolos e caracteres imagéticos. O objetivo geral foi investigar como os futuros docentes percebem essas práticas linguísticas e suas influências na escrita escolar de seus alunos. Para alcançar tal objetivo foram elaborados grupos focais como espaço de discussão do tema, e, junto aos professores em formação inicial pesquisados, discutiu-se se e como o internetês está presente na escola, e suas consequências na escrita escolar. Durante a realização da pesquisa fomos surpreendidos pela pandemia do covid-19 e seus desdobramentos, como, no campo educacional, o ensino remoto, o que culminou na presença do internetês ainda mais marcantemente nas práticas linguísticas dos alunos. Os dados qualitativos foram apreciados pela perspectiva da análise temática, somada as contribuições dos olhares que integram nosso quadro teórico, cujo enfoque vai ao encontro da premissa da língua como prática social. A partir da análise das narrativas dos professores em formação, foi possível perceber que entre os participantes da pesquisa, há tanto aqueles que percebem o internetês na sala de aula em uma perspectiva negativa, como também há aqueles que o tem como um dialeto com influências positivas no ambiente escolar. Consideramos que, para ampliar as discussões sobre o tema, é preciso investir nos espaços de formação de professores a fim de formar docentes que lidem pedagogicamente com o fenômeno linguístico intrínseco à cultura digital que chegou às escolas.

Physical Layer Security in Satellite Communication System Using Nulling Based Approach
Authors: Anand Prateek , K. Arti M. 
Published: November 2023

Abstract
The broadcast properties of satellites communication makes transmission less susceptible to eavesdropping or even negative obstruction. Physical Layer Security (PLS) technique prevents privacy of data sent by the sender from being intercepted by illegal hackers, which ensures the confidentiality and transmission security between the sender and authorized users. The evolution of mobile communications has brought new challenges to physical security research. Data security techniques implemented at the physical layer of satellite communication are proving to be effective on many parameters. Considering the down-link of a satellite communication system, with multiple antennas at Earth station (ES), Eavesdropper, as well as on satellite, an eavesdropper wants to hack the signal of the satellite to the ES. We propose a method by which the signal received by the eavesdropper is in a meaningless form. The proposed method uses nulling based approach, in which the signal transmitted by the satellite gets multiplied by a beamforming vector, which is selected in a manner so that no information can be received by the eavesdropper. The performance of the received data at ES is analyzed in terms of symbol error rate.

Abstract
Despite the importance of surface water resilience to local ecosystems in arid and endorheic basins, the current understanding of surface water sensitivity to climate-driven hydrologic perturbations in such environments remains limited to basin-scale water budget analysis and often ignores the complex relationships between these surface waters and sources of recharge. We investigate the driving factors of surface water variability and drought vulnerability for the Altiplano-Puna region of the Andes in South America with satellite imagery via the Landsat-based JRC Surface Water Product and the Sentinel mission. We further identify areas of surface water-adjacent groundwater discharge through the normalized difference vegetation index and compare fluctuations in vegetated area to variability in surface water inundation. Regression analysis between surface water inundation and monthly average temperature through FLDAS and precipitation through Terraclimate also provides an opportunity to assess climate-driven sensitivity. Surface waters throughout the Altiplano-Puna show resilience to a prolonged region-wide drought which occurred between 2003 and 2012. However, high-elevation (>4,000 masl) surface water bodies exhibit statistically significant declines in surface water inundation, but these same surface water bodies show the highest post-drought rebounds. Increased sensitivity in vegetated area fluctuation adjacent to areas of higher surface water drought sensitivity indicates that surface water bodies are reliant on groundwater discharge. An exploration of basin attributes further suggests that higher-elevation basins experience higher variability in groundwater and surface water fluctuations, suggesting not only that both systems are closely coupled but also that increasing precipitation at higher elevations introduces more variability in the hydrologic pathways to local surface waters. We present the first regional study of arid, endorheic basins to define mechanisms of surface water resilience and determine the importance of groundwater discharge dynamics in such environments. This study further provides a framework for assessing surface water resilience for both the Altiplano-Puna and other similarly arid regions (e.g. the Tibetan Plateau, the Great basin, etc.).

Abstract
The characteristics of floor failure and stress changes during the mining process of protective layers are crucial for determining the effectiveness of pressure relief. Three boreholes were designed in the 21104 fully mechanized mining face of Hulusu Coal Mine to implant optical fibers into the floor of the working face. A fiber optic monitoring system was established to monitor the dynamic evolution of stress in the floor rock mass at different mining distances. Based on the information entropy in information theory, the monitoring results in the fiber optic monitoring system are calculated to obtain the stress information entropy at different mining distances. A quantitative dynamic analysis is conducted on the stress change process of the mining floor rock layer, and the stress change law of the protective layer after mining is verified through numerical calculation and similar simulation experiments. The results indicate that the evolution of stress information entropy can be divided into four stages, namely the original rock stress stage, stress concentration stage, stress release stage, and stress recovery stage. The stress information entropy shows a fluctuating upward trend, indicating that coal seam mining leads to a decrease in the orderliness of the overlying rock system and an increase in disorder. In different spatial evolution processes, there are also significant differences in stress information entropy. In the vertical direction, the entropy value of shallow rock layers changes greatly, while the entropy value of deep rock layers changes slightly. Mining leads to a decrease in the orderliness of the entire overlying rock system, an increase in stress information entropy, and a fluctuating upward trend in stress information entropy. The information entropy of overlying rock deformation and re compaction increases, but the degree of change of the former is greater than that of the latter. The Brillouin fiber optic sensing technology provides a new method for monitoring the stress changes in the protective layer mining floor, achieving quantitative analysis of floor rock failure.

Abstract
Objective
Assisted oocyte activation (AOA) is applied in male factor infertility for improving the successful fertilization rate. However, the safety and efficacy of AOA technique remain unknown. The aim of this study is the comparison of two different mechanical and chemical AOA methods on pre-implantation morphokinetic development of embryos derived from oligoasthenoteratozoospermia patients.
Methods
This study was applied in 65 cycles achieved between 2020 and 2022; 137 embryos were derived from ICSI-chemical AOA cycles and 124 embryos from ICSI-mechanical AOA cycles. Morphokinetic characteristics of all embryos were monitored via a time-lapse system.
Results
Our results showed similar morphokinetic development in both early and late-stage embryonic development in two different groups of this study.
Conclusions
Our results suggest that both mechanical and chemical methods AOA have the same effect on morphokinetic pattern of pre-implantation embryo development in oligoasthenoteratozoospermia.

Published: November 2023

Abstract

Control of electrical doping is indispensable in any semiconductor device, and both efficient hole and electron doping is required for many devices. In organic semiconductors, however, electron doping has been essentially more problematic compared to hole doping because in general organic semiconductors have low electron affinities and require dopants with low ionization potentials that are often air-sensitive. Here, in this study, we adapt an efficient molecular doping method, so called ion-exchange doping, to electron doping in a polymeric semiconductor. Reduction of the polymeric semiconductor is initiated via one electron transfer from molecular dopants, then the ionized dopants in the resulting air-unstable films are replaced with the secondary ions via cation-exchange. When a specific bulky molecular cation was employed as the secondary ion, ambient stability and crystallinity of doped polymeric semiconductors were improved compared to conventional methods. The presented strategy can overcome a trade-off relationship between reducing capability and ambient stability in molecular dopants, and a wider selection of dopant ions will help to realize ambient-stable electron conductors.
Assessing the quality of microservice and monolithic architectures: systematic literature review
Authors: Hussein Saad , Lahami Mariam , Torjmen Mouna 
Published: November 2023

Abstract

Scalable solutions have become extremely required with the emergence of cloud computing and the transformation to microservices-based applications. Although creating software is challenging, creating a scalable system is far more challenging. A microservices architecture is a collection of smaller, independently deployable services as opposed to a monolithic application, which is created as a single integrated entity. The objective is to pave the way for a generic framework that helps companies and industries in their migration to microservices and get a methodology for evaluation that a company might use to compare its utilisation of microservices. This effort aims to enable enterprises to assess their capacity to successfully adopt microservices through the use of quality criteria. We conducted a Systematic Literature Review (SLR) to find 48 selected research papers over the last four years (2020–2023) and compile pertinent research that provides data about contrasting the quality attributes of monolithic and microservice applications. This study demonstrates how choosing quality attribute metrics can provide a more accurate evaluation of both monolithic and microservice systems. The shift from a monolithic to a microservice-based architecture will be made possible thanks to the relevant indicators we provide. According to the findings of the literature review, the most important quality attributes and subcharacters are: performance, scalability, coupling, cohesion, deployment, security, development, complexity, maintainability, and availability. The findings indicate a rising tendency in the research community towards quality-driven migration to microservices, and numerous researchers take quality characteristics into account in the methods they outline in their work and include quality improvement as one of the migration aims.

Published: November 2023

Abstract
In order to refine the displacement field of the background oriented schlieren method, a super-resolution method based on deep learning has been newly proposed in the study, and were compared with the bicubic interpolation. The gradient loss functions were firstly introduced into the hybrid downsampled skip-connection/multi-scale (DSC/MS) model to improve the reconstruction effect. The reconstruction effects of the new loss functions were compared with that of the traditional MSE loss function. The results showed that the Laplace operator with average pooling had better performance than the origin loss function in all the indexes including PSNR, MSE, MSE of the gradient and the max MSE. In these four indexes, MSE of the gradient and the max MSE performed especially better than the others, where the MSE of the gradient reduced from 3.90E-05 to 3.30E-05 and the max MSE reduced from 0.392 to 0.360.

Dreaming of a Brighter Future? The Impact of Economic Vulnerability on University Aspirations
Authors: Watson Barry , Kong Nancy , Phipps Shelley , Daley Angela 
Published: November 2023

Abstract
We investigate how economic vulnerability (measured in terms of poverty and economic insecurity) impacts the educational aspirations of youth, age 12-15, within an inequality of opportunity framework. Using the Canadian National Longitudinal Survey of Children and Youth, we find that poverty is associated with reduced university aspirations from the perspective of the youth (8-9 percentage points) and their mother (11-13 percentage points). Further, poverty incidence matters more than depth. Using the dissimilarity index, circumstances contribute to about 20-25 percent of the inequality in educational aspirations, and a Shapley decomposition of these circumstances suggests that, of this observed inequality, 10-15 percent is due to poverty. Interestingly, economic insecurity is not associated with educational aspirations, and this result persists regardless of how we measure insecurity. This may be due to the fact that, over time, poverty is more likely to persist than economic insecurity. Consequently, while the latter may be seen as a temporary shock, the former may create a feeling of hopelessness, thereby reducing aspirations. Controls for academic effort, including standardized test scores, daily reading, and getting good grades do not impact these findings. Results therefore suggest that alleviating child poverty may improve educational aspirations at a critical time in a youth's life.

Assessment of various types of household water consumption based on critical consumption behaviours using a novel criterion in metropolitan cities
Authors: Abbasi Ali , Kadkhodaei Mohsen 
Published: November 2023

Abstract

Rising demand for urban water consumption, especially for household uses, has led to a water crisis in various cities around the world. The amount of household water consumption, as the most important part of urban water use, is significantly affected by the consumers’ behaviours and water saving equipment used. Therefore, it is necessary to mitigate the household water demand by applying effective strategies such as promoting the water conservation culture and installing water saving appliances. For this purpose, consumers’ behaviours should be evaluated and various types of household water consumptions should be ranked. In this research, by distributing questionnaires among the citizens of Mashhad city, the consumer behaviours were evaluated. Confirmatory factor analysis (CFA) was applied to examine the similarity of people's consumption behaviours in various household uses. The results showed that people's consumption behaviours are different. By defining the impact coefficient index and the average impact coefficient index, various types of household water consumptions were ranked using Friedman and Wilcoxon statistical tests. Based on the results, changing consumption behaviours in bathing has the highest efficiencies on reducing water consumption. Dishwashing, using the washing machine and sanitation (toilet) were jointly ranked second. Car washing and tooth brushing were both equally important and ranked third.
Time-dependent Study of Dust Distribution in a Protoplanetary Disc
Authors: Gholipour Mahmoud 
Published: November 2023

Abstract
Recent observational data from ALMA indicate the absence of emission from small dust grains within the inner radius of certain protoplanetary discs, known as transition discs. In this study, we examine the evolution of the dust-to-gas ratio in different regions of a protoplanetary disc (PPD). Using observational reports on the dust opacity in a PPD, our aim is to investigate the dust-to-gas ratio (also known as the grain content factor) in the presence of MRI-turbulence in the disc. Building upon the observational data and previous analytical works, we propose an analytical model that emphasizes the crucial role of dust opacity in the dust distribution of a PPD. Specifically, our model focuses on the energy balance between viscous heating and radiative cooling in a PPD. Through this model, we determine the dust-to-gas ratio in three regions of a PPD. Our findings reveal a significant decrease in the dust-to-gas ratio in the second region of the disc, which holds potential importance in the study of transition discs. Additionally, we observe that the dust-to-gas ratio in the third region is several times larger than in the other regions, which may prove valuable in the study of the formation of large Jovian planets located farther from the proto-stellar object.
Retinal pigment epithelium elevation values as a marker in determining the anatomical prognosis and treatment regimen of type 2 macular neovascularization
Authors: Isık Mehmed , Yozgat Zübeyir 
Published: November 2023

Abstract

Objective
To determine the prognostic value of the RPE elevation area or volume and the other morphological OCT biomarkers in nAMD cases.
Methods
Fifty-one eyes of 51 naive patients with nAMD were included. The treat-and-extend regimen was used. A total of 3 intravitreal doses of bevacizumab (IVB) were administered (loading phase). After the loading phase, two groups were divided according to the presence of IRF/SRF and the absence of IRF/SRF. Three doses of intravitreal aflibercept were loaded in eyes with refractory or recurrent fluid. OCT was used to evaluate central retinal thickness, morphological characteristics, center 3 and 5 mm RPE elevation area and volume.
Results
After the IVB loading, 27 of 51 patients had IRF/SRF, while 24 did not. When the BCVA change in the 3rd, 6th and 12th months was compared between the groups according to the presence of SHRM, the gain was higher in the non-SHRM group. The absence of a sub-RPE hyperreflective column was found to be a risk factor for fluid resistance after IVB loading. Central 3 mm RPE elevation area and volume were different between the two groups. It was observed that while the baseline RPE-3mm-area and baseline RPE-3mm-volume values were incerasing, the risk of fluid resistance after IVB loading was significantly increased.
Conclusion
The RPE elevation area at the central 3 mm at the first presentation may have value as a marker in determining the prognosis of nAMD, and may be considered as an indicator for which treatment regimen can be chosen initially.
