Published: June 2023

Bacillus oceanisediminis PM 08, isolated from soil and seawater in southern Thailand, was evaluated as a potential biosurfactant with effective emulsifying properties. This strain produced a biosurfactant with a maximum emulsifying activity of 65% and a surface tension of 22.67 mN/m after 60 hours of cultivation under cultivation conditions. The yield of biosurfactant obtained by extraction with chloroform: methanol (2: 1, vol/vol) was 1.55 g/L. The stability of the biosurfactant was effective over a wide range of pH, temperature, and salinity. The high thermostability of the biosurfactant was determined using a thermal simultaneous. In addition, a preliminary chemical composition using FT-IR revealed that it is a glycolipid biosurfactant. The properties of this biosurfactant make it a good product for many industrial applications under extreme conditions.
Evolving Nature of Financial Intermediation and Economic Growth: Insights from a Bayesian Vector-Autoregression Analysis
Authors: Chatterjee Ujjal K.
Published: June 2023

We compute the growth of financial intermediary (FI) assets as an indicator of liquidity provided by intermediaries to the economy, as is done in the existing literature, and analyze its impact on the economy. We find that shocks to aggregate FI assets have a significant impact on U.S. real GDP and other macroeconomic indicators. Furthermore, shocks to assets of individual FIs also impact economic growth. However, our sub-sample analysis reveals notable shifts in the nature of financial intermediation: i) an increasing importance of market-based intermediaries, such as securities brokers and dealers, while the relationship between banks and the overall economy has diminished; ii) mutual funds demonstrate a greater impact compared to pension funds, underscoring their relative significance in driving economic outcomes in recent years; iii) insurance companies and shadow banks exhibit consistent significance across the sub-sample periods. These results suggest adopting a holistic approach to policymaking that considers various FIs, enhancing regulation and oversight of systemically important non-bank financial institutions, and monitoring of large insurers to mitigate the risk of financial instability.
Effect of Vibrator Parameters and Physical Characteristics of Parts on Conveying Velocity
Authors: Vellingiri Vishwa Priya , Sadasivam Udhayakumar
Published: June 2023

Automation is generally employed in the area of orienting, lifting, and moving parts for production in industries including automotive, electronic, food, and packaging. With the help of automation, it is possible to reduce the manufacturing time and labour required. The most adaptable tools for feeding small, designed pieces during part assembly are vibratory feeders. Industries have been effectively using vibratory feeders for more than 30 years, indicating that such technology is advanced. Although research in this area has not been lacking, a fundamental understanding of the interactions between a part’s physical characteristics and the various vibratory feeder operating parameters in relation to optimal performance, defined as conveying a part with maximum stability and maximum velocity, remains lacking in linear feeders. While several papers discuss the effect of vibratory parameters (excitation frequency and amplitude of vibration) and the coefficient of friction, the effect of characteristics of part (l/w ratio and mass) is neglected. In this work, the effect of these factors on the conveying velocity of prismatic parts made of aluminium and brass on a horizontal track without inclination was determined, and an attempt was made to develop a predictive model based on the above factors. Using Taguchi’s design of experiments (DOE), an L16 orthogonal array was designed. A response table for the signal-to-noise ratio has yielded optimal values for each parameter taken into consideration. ANOVA predicted frequency as the most influential parameter, followed by the coefficient of friction. The regression analysis yields an R2 value of 99.3 % for aluminium and 98.7 % for brass. The results of the regression model and random experiments show a high correlation of 91.66 %. This model is required to set the desired conveying velocity of parts so that continuous flow can be maintained in automated assembly or packaging industries.
Collaborative Journalism and Normative Journalism: Lessons from Latin American Journalism
Authors: Mesquita Lucia
Published: June 2023

Collaboration in journalism has become increasingly important, in the face of the challenges posed by digitalisation and platformization. The development of information and communication technologies has led to collaborative journalism committed to democratic and public-oriented methods. However, it is unclear how this commitment is reflected in practice, and whether it varies according to political, economic and media system contexts, especially in non-democratic and authoritarian regimes. Latin America is a diverse region with a history of social, economic and political instability, alternating between authoritarian and democratic regimes. This context can help answer the research question of this study, which aims to understand the commitments, norms and values of practitioners of collaborative journalism in various contexts. The thematic analysis of 36 semi-structured, in-depth interviews conducted in Latin America found that practitioners of collaborative journalism commonly share normative journalism roles, practices, values and norms. The study suggests a need to reinforce, restore and reform normative journalism norms and values, particularly in non-democratic, authoritarian, and developing democracies. This study can be a valuable resource for future researchers exploring journalism, collaborative journalism and investigative journalism beyond the context of Western liberal democracies.

TiAlN and TiAlN gradient films were deposited on Si substrates by reactive pulsed DC magnetron sputtering. The crystal structure and morphology of TiAlN films were characterized via X-ray diffraction (XRD), and field emission scanning electron microscope (FE-SEM), respectively. Moreover, elemental composition, hardness, and adhesion of TiAlN films were analyzed by energy-dispersive X-ray spectroscopy (EDS), nanoindentation test, and scratch test, respectively. The TiAlN films and TiAlN gradient films showed columnar structure and cubic crystal structure with different orientation planes. The elemental mapping of TiAlN gradient films clearly demonstrated the TiAlN gradient films. TiAlN gradient films have slightly lower hardness compared to TiAlN films while adhesion of the films increases.

Published: June 2023

Microsatellite markers previously developed for other leguminous species were tested for cross-genus transferability and evaluated for their potential usefulness in providing an improved assessment of the genetic relationships between two closely related taxa belonging to Onobrychis genus (Fabaceae). Candidate microsatellite markers were tested for polymorphism and replicability in sixteen populations of O. montana DC. subsp. transsilvanica (Simonk.) Jáv. and O. montana. Out of the 23 SSRs, there were identified seven polymorphic loci. In total 32 alleles were detected and the number of alleles per locus varied from two to six. PIC values ranged from 0.375 to 0.6454, and four SSRs displayed a PIC > 0.5. Relative uniform rates of genetic diversity were obtained. In case of O. montana DC. subsp. transsilvanica (Simonk.) Jáv. the observed and expected heterozygosity ranged from 0.100 to 0.952 and from 0.219 to 0.525, respectively, while for O. montana ranged from 0.166 to 0.750 and from 0.083 to 0.375, respectively. Seven polymorphic SSRs with clear and reproducible amplification were identified. These markers proved to be very efficient for unambiguous population discrimination based on both geographic and taxonomic criteria. Hereafter, these SSR markers can be used as tools for evolutionary studies in Onobrychis genus, as well in providing knowledge on patterns of the species phylogeography.
A socialização da educação em Stephen Duggan e Antonio Gramsci – as “sombras fabricadas” em meio às tensões do Estado moderno entre os séculos XIX e XX.
Authors: Das Chagas Marcos Antonio Macedo
Published: June 2023

A elaboração do presente artigo se deu a partir de aprimorada pesquisa bibliográfica, envolvendo o livro A student´s textbook in the History of Education de autoria de Stephen Duggan. Particularmente nos concentramos no Chapter XVI: Socializing Education Thru Philanthropy And Thru State Control (Capítulo XVI: Socializando a educação por meio da filantropia e do controle do Estado). Duggan foi professor do College de Nova Iorque e, concomitantemente, pesquisador no campo da História da Educação, vivenciando as hodiernas relações sociais e econômicas ocorridas nos Estados Unidos e na Europa entre os séculos XIX/XX. Seu material é raro e sem tradução no Brasil. Tivemos acesso ao compêndio a partir do doutoramento em educação, na disciplina “Tópicos de Pesquisa”. Na ocasião, abordamos em seminário as perspectivas da “socialização” no espaço educacional levantadas por Duggan, cotejando-as com paradigmas científicos do pensamento de Antonio Gramsci. Tais indagações, em função das tensões educacionais de momento, ainda parecem ativas.
Retalhando o que nos fere discurso de resistência das mulheres no Poetry Slam
Authors: Neves do Nascimento Natã
Published: June 2023

Este trabalho se propõe a analisar a narrativa das mulheres expressa em versos de poesias das competições de poetry slam que apresentam uma realidade de dor e sofrimento que não lhes gera um silenciamento, tornando-se, contrariamente munição para resistir e prosseguir. Essa juventude tem produzido riscos poéticos de sobrevivência por meio de seus versos na competição. Dentre estes, destacamos as narrativas das mulheres que apresentam suas vivências por meio de poesias na competição. Diante da participação das mulheres na competição desejamos aprofundar a discussão sobre essas narrativas e suas lutas pelo direito de estarem vivas e ser ouvidas. A partir da contribuição dos pensadores Walter Benjamin, Gilberto Velho, Conceição Evaristo e Chimamanda Ngozi apresentaremos como a dor e a sobrevivência estão presentes nos versos, bem como na vida cotidiana de cada uma dessas poetas.
Violência e as produções de “verdades”: (des)encontros discursivos entre as mídias hegemônicas e juventudes do loteamento Kephas (RS)
Authors: Oliveira Tatiane De , Zucchetti Dinora Tereza , Marques Pâmela Marconatto
Published: June 2023

Este artigo é oriundo de um recorte de pesquisa em desenvolvimento, no âmbito do mestrado. Utiliza as contribuições teórico-metodológicas de Foucault (2008) para analisar os (des)encontros entre as notícias sobre a violência no Loteamento Kephas – Novo Hamburgo (RS) – e as narrativas de nove jovens moradores do território. Busca compreender se as “verdades” produzidas pelo dispositivo midiático contribuem para a produção de estigmas sobre o Loteamento, ao passo que se propõe a escutar as narrativas de jovens produzidos ali. Conclui-se que os discursos jornalísticos contribuem para a produção de estigmas, pois das 76 reportagens sobre o território, veiculadas entre 2017 e 2021, 40 tratavam da temática da violência. Destacam-se as rondas policiais e a apreensão de entorpecentes. Por outro lado, os jovens entrevistados observam a redução da violência ao longo dos anos e denunciam que a mídia coloca em emergência apenas uma das histórias possíveis de ser contada sobre o Kephas.

This study aimed to evaluate the yield and chemical composition of the essential oil of immature fruits of C. deliciosa varieties cultivated in Rio Grande do Sul using laboratory (hydrodistillation) and industrial (scarification) methods. During the period of industrial processing (scarification), fruits from the same batches were sampled for laboratory hydrodistillation. Essential oil yield and chemical composition were evaluated by GC/MS and GC-FID The average yield obtained was 0.07 wt.% (hydrodistillation) and 0.53 wt.% (scarification). EO yield followed a quadratic model regarding sample collection time in both methods, indicating an optimum time for fruit collection regarding EO yields. According to EO characterization, 24 different compounds were identified in hydrodistillation and 19 in scarification. The major compounds detected were limonene (66.5 – 71.3 wt.%) and γ-terpinene (12.1 – 18.4 wt.%), regardless of the extraction method. A greater number of compounds with content above 1.0 wt.% was found in the oil obtained by hydrodistillation. The scarification method provided greater extraction yield and a smaller number of compounds relative to the essential oil of mandarins extracted by hydrodistillation.

Authors: Wirkus Łukasz
Published: June 2023

The aim of the article is to show the role of family probation officers in preventing juvenile demoralization and crime in the context of the Act of June 9, 2022 on the support and rehabilitation of minors. The considerations were supplemented with a statistical picture of juvenile delinquency in Poland and family court decisions in cases of demoralization and criminal offenses. An example of practical implications is the concept of preventive and social rehabilitation activities at the pre-trial (educational team in school) and judicial levels, which play a significant role in the system of preventing social maladjustment of children and adolescents.
The statute of limitations for sexual offenses committed against minors
Authors: Krajewski Radosław
Published: June 2023

The article concerns changes in the limitation periods for sexual offenses committed to the detriment of minors. They took place in 2008, 2014, 2015 and 2022 (entering into force on October 1, 2023). Subsequently, these periods were extended. Originally, it was a period of 5 years after the victim turned 18, then not earlier than before he turned 30, and currently he turned 40. The differences also concerned the details of the statute of limitations for these crimes. It was and still is part of the entirety of regulations aimed at increased protection of minors against sexual abuse and bringing to justice the perpetrators of such acts, including those committed years ago. It is important that the standard of this protection is higher than provided for by international obligations. It should also be emphasized that after the latest amendment, the punishment of the most serious of these crimes does not expire. The aim of the study is to analyze solutions in this area with references to the achievements of legal science and to present my own observations on them.

The commented judgement is yet another statement of the Supreme Court concerning the jurisdiction of the court in cases relating to civil claims of reinstated officers. However, the analysed judgement is significant because it determines not only the jurisdiction of common courts (which has already been confirmed in previous case law) but also determines the character of the benefit granted under Article 42 paragraph 5 of the Police Act. The interpretation of this provision adopted by the Supreme Court opens the way for reinstated officers to seek compensation from the State Treasury over the limit specified in this provision

Los trabajadores de salud se enfrentan a una gran variedad de riesgos en el trabajo, entre las cuales se encuentran lesiones por pinchazos de agujas, alergias al látex, violencia y estrés, a su vez los riesgos biológicos pueden ser dadas por infecciones agudas y crónicas, así como también a las reacciones alérgicas y tóxicas provocadas por agentes biológicos y sus derivados o productos. Esta investigación tuvo como objetivo identificar los casos de exposición de riesgos laborales en el personal de salud. Se realizó un estudio con diseño cualitativo de revisión sistemática de artículos publicados entre los años 2018 – 2022 en bases de datos como PubMed, Redalyc y Cochare Library, en los cuales se utilizaron términos MeSH “biological risk”, “biological accidents”, “riesgo biológico”, “accidentes biológicos” “bioseguridad” “accidente laboral” “personal de salud” “lesiones cortopunzantes”, “laboratory” “protocolos de bioseguridad”. Los resultados señalaron que en el personal de la salud los riesgos se dan en gran parte en un nivel medio-alto, donde predomina el desconocimiento como factor predisponente; de igual forma la exposición de micro y macro organismos que pueden causar daño provocando un riesgo biológico laboral. Mediante las revisiones de los estudios se evidencia un gran porcentaje en profesionales de área de enfermería y laboratorio clínico de presentar accidentes biológicos, siendo la extracción de sangre y la toma de otro tipo de muestras las de mayor incidencia, además que existe un alto grado de incumplimiento en los protocolos de bioseguridad, lo que acrecienta la eventualidad a padecer riesgos biológicos.

Published: June 2023

Background and Aims: Among patients at very high cardiovascular risk, some are more likely to experience recurrent cardiovascular events. In May 2022, an article was published in the European Heart Journal proposing different definitions of patients at extreme cardiovascular risk. However, the process of defining such patient is still ongoing and more data on its prevalence are needed. Our aims consisted in assessing the prevalence of patients at extreme cardiovascular risk in cardiological rehabilitation and in evaluating the clinical features of such patients. Furthermore, we wanted to establish how the extreme cardiovascular risk condition correlates with the functional improvement obtained during cardiac rehabilitation. Methods: The study included 938 patients suffering from atherosclerosis who attended the cardiological rehabilitation of Niguarda Hospital in Milan. Patients classified as at extreme cardiovascular risk were compared with the remaining patients and a multivariate linear regression was performed with absolute functional improvement as the dependent variable. Results: Among 938 patients, 26.9% belong to the category of extreme cardiovascular risk. Patients at extreme cardiovascular risk showed a higher average age (67.8 ± 10.4 vs 64.1 ± 11.1 years; p ≤ 0.001), a higher prevalence of significant comorbidities (peripheral arterial disease, cerebrovascular disease, dyslipidemia, diabetes, chronic kidney disease, hypertension) and a lower functional improvement during cardiac rehabilitation (102.9 ± 68.6 vs 138.1 ± 86.5 m; p ≤ 0.001). At multivariate analysis extreme cardiovascular risk remains a significant determinant of the absolute functional improvement at Six-Minute Walking Test obtained during cardiac rehabilitation with b = -0.137 and p = 0.035, together with female sex (b = -0.136; p = 0.035). Conclusions: Extreme cardiovascular risk is a widespread condition among patients with chronic coronary syndrome and adversely affects the patient’s functional improvement during cardiac rehabilitation. The identification of patients at extreme cardiovascular risk is a goal to be pursued in order to intensify secondary prevention strategies.
Rock Magnetic and Mineralogical Properties of Lateritic Soil Profiles Developed on Two Different Parent Rocks in Northern Kerala, South-Western India

The rock magnetic and mineralogical properties of two lateritic soil profiles developed on two different parent rocks (khondalite and granite) in northern Kerala, south-western India were investigated to better understand pedogenic processes under tropical climate. Field investigations reveal the presence of various horizons in the lateritic profiles, such as saprolite, mottled zone, pebble horizon and top soil. The particle size, rock magnetic, Vibrating Sample Magnetometer (VSM), Scanning Electron Microscopy (SEM)-Energy-Dispersive X-ray Spectrometer (EDS) and X-Ray Diffraction (XRD) analyses were performed on samples collected from different horizons of the two profiles. Magnetic susceptibility (χlf) values of the lateritic profiles vary from 9.97 to 1717.04 x 10-8 m3 kg-1, with the granitic profile exhibiting overall higher values. The percentage frequency-dependent susceptibility (χ %) ranges between 0 % and 13.9 %. The XRD data reveal the presence of kaolinite, gibbsite (except for top soil layer) and quartz along with magnetic minerals like magnetite, hematite and goethite. The upper horizons (top-soil and pebble horizon) exhibit high values for concentration dependent magnetic parameters like χlf and χfd%, whereas, the lower horizons (saprock, saprolite, pallid zone horizons) exhibit low values. The tropical soils in the region have undergone a higher degree of pedogenesis with increased magnetic mineral concentration compared to temperate soils. The magnetic enhancement in the topsoil may be due to the neoformation of ultra fine-grained SP magnetite/maghemite (with minor anti-ferro magnetic component), aided by sufficient Fe supply, alternate wetting and drying cycles, dehydration, oxidation and redox conditions.

The increasing demands for groundwater resources and marked changes in climate over the years have imposed immense pressure on global groundwater resources. The present study has been undertaken to emphasize the expediency of remote sensing and geographic information system (GIS) to delineate the groundwater potential of a small tropical river basin of Kerala (India), viz., Thuthapuzha River Basin. Atotal of 10 geo-environmental thematic layers such as Geology, Geomorphology, Drainage density, Rainfall, Soil, Slope, Topographic Position Index, Groundwater level and Curvature were prepared and studied for groundwater potential zone demarcation. Weights assigned to each class in all the thematic maps are based on their characteristics and water potential capacity through Weighed overlay method (WoM). The groundwater potential zone map subsequently obtained was classified into five classes-very high, high, moderate, low and very low. The study reveals that about 63% of the river basin is covered under a moderate groundwater potential zone. The low and high groundwater potential zones are observed at 27% and 9%, respectively. The area under very high and very low potential zones is recorded only in very limited areas (>1%) in the basin.

Heavy metal enrichment in urban soils demarcates a major ecological concern. The emerging industries, settlements and agricultural lands in bank of Kabini River resulted in prominent changes in water and soil geochemistry. In present work, a total of 20 soil samples from Kabini Basin have been checked for trace metals concentration and assessed following multivariate statistical approach. The PCA has been conducted to characterize the trace metals as per the common source of origin. The factors distinguished the heavy metals into 3 components with overall variance of 82.53%. Higher loading of various heavy metals indicates natural and anthropogenic interferences in soil. The baseline data generated from the present study provides the insight over the concentration of heavy metals, which would further be helpful in conservation and management of soil resources of the basin.

Innovación MedIÁtica: aplicaciones de la inteligencia artificial en el periodismo en España
Authors: Mondría Terol Teresa
Published: June 2023

Esta investigación trata de identificar los distintos usos de la inteligencia artificial (IA) en la rutina productiva de los medios periodísticos. A través de entrevistas en profundidad a profesionales del periodismo y la revisión bibliográfica se observa cómo afecta la IA a las dinámicas de la redacción, cómo se desarrolla en casos reales y qué perfiles son necesarios para su implementación en tres casos de estudio españoles: RTVE, El País y Newtral. Se concluye que la evolución tecnológica del sector y la introducción de la IA requieren de un cambio de mentalidad en las redacciones, superar el miedo a la sustitución, poner en valor la capacidad creativa y las decisiones editoriales humanas. También se identifica la emergencia de perfiles mixtos -periodismo e informática- para poder comprender proyectos de inteligencia artificial e introducirlos en la rutina periodística.

The Effect of Zeolite (Clinoptilolite) as a Feed Additive and Filter Material for Freshwater Aquariums
Authors: ÖZ Meryem , ARAL Orhan
Published: June 2023

Ammonia, which occurs as a natural result of aquaculture in production facilities, has a negative effect on the quality of aquaculture water and aquatic organisms. In this study, it was aimed to determine the effect of zeolite in fish feed and in water, which has the ability to adsorb ammonium, on ammonia removal. In the study, 12 different experimental groups were organized by creating 0, 2, and 10% ratios for fish feed (G1-G3), groups that zeolite only in water (G4, G5), and combinations (zeolite and/or in water/in feed) of 0, 7, and 20 g/L amounts to water (G6-G12). When NH3 and TAN data of G1-G3 were examined, it was determined that although there was no statistical difference, it decreased proportionally with the increase in the amount of zeolite in the feed. The difference between water temperature, dissolved oxygen, pH, NH3 and TAN values in G4 and G5 groups was found to be insignificant. The dissolved oxygen, pH, NH3 and TAN values between the groups (G6-G12) were statistically different. As a result, it was determined that 10% addition of zeolite into the feed decreased the TAN values by 37%, and the addition of 10% into the feed and 20 g/L into the water decreased the TAN values by 45%. When the results are evaluated from another point of view, considering the economy and ease of use, it is concluded that 2% zeolite in feed and/or 7 g/L in water can be recommended for aquatic species with high tolerance to ammonia values.
Effect of a Natural Adsorbent Mixture (Zeolite and Leonardite) on the Reduction of Ammonia Caused by Fish Feed
Authors: ŞAHİN Dilek
Published: June 2023

In this this research, the utilization of zeolite (clinoptilolite) and leonardite mix, which are the natural adsorbents that can be used to provide optimum water conditions for aquaculture, was investigated. Three groups with 3 replications were formed and a commercial aquarium fish feed having 47.5% crude protein was added as the ammonia factor in three different concentrations (0.2 g feed/500 ml tap water, 0.4 g/500 ml tap water, 0.6 g/500 ml tap water). Ammonia increases resulted from 3 different amounts of feed were monitored for 7 days. At the end of this period, the adsorbent mixture, which has water-regulating properties, was added to the experimental groups at a ratio of 1:2 (clinoptilolite:leonardite) to remove ammonia, which is harmful for aquatic organisms, and ammonia decreases was determined at regular intervals. NH3 value reached its highest (0.7 mg/L) at the end of the stage where the ammonia values from the feed were measured. After this period, it started to decrease with the addition of natural adsorbents (mixed clinoptilolite-leonardite) and the lowest ammonia value was determined at the end of the 6th measurement (0.07 mg/L). As a result of this study, it was determined that the clinoptilolite:leonardite mixture has a positive influence on ammonia removal in freshwater aquariums.

Systematic Review Protocol for Sham Acupuncture Validation Research
Authors: Lim Sung Min
Published: June 2023

Background: Streitberger and Park sham needles have been developed and used as non-penetrating sham acupuncture needles that can be blinded in randomized controlled clinical trials assessing the efficacy of acupuncture. Ideal sham acupuncture should not be distinguishable from an actual acupuncture treatment provided to the experimental group to ensure patient blinding; additionally, it should not have any physiological or biological effect. Providing evidence for such sophisticated sham acupuncture devices is critical, as control settings in clinical studies are based on research verifying their validity.Methods: Three core electronic databases - PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials - will be used to search for validity verification studies of sham acupuncture devices. Clinical studies that verify the validity of non-penetrating sham acupuncture devices will be included in the review.Results: The study design, participant information, experimental and control groups, study population’s experience with acupuncture, outcome variables, and results of studies that verify the validity of sham acupuncture devices will be systematically reviewed.Conclusion: This systematic review of validity verification studies of sham acupuncture devices is expected to help the development of more sophisticated sham acupuncture, as well as the design of studies verifying its validity in the future.
Memory-Safe Elimination of Side Channels
Authors: Soares Luigi , Pereira Fernando Magno Quintão
Published: June 2023

In this project, we find a new service for partial control-flow linearization (PCFL), a code transformation initially conceived to maximize work performed in vectorized programs. We show that PCFL can be employed as a defense mechanism against timing attacks. This transformation is sound: given an instance of its public inputs, the partially linearized program always runs the same sequence of instructions, regardless of secret inputs. Incidentally, if the original program is publicly safe, then accesses to the data cache will be data oblivious in the transformed code. The transformation is optimal: every branch that depends on some secret data is linearized; no branch that depends on only public data is linearized. Therefore, the transformation preserves loops that depend exclusively on public information. If every branch that leaves a loop depends on secret data, then the transformed program will not terminate. Our transformation extends previous work in non-trivial ways. It handles C constructs such as “break”, “switch” and “continue”, which are absent in the FaCT domain-specific language (2018). Like Constantine (2021), our code transformation ensures operation invariance, but without requiring profiling information. Additionally, in contrast to SC-Eliminator (2018), our implementation handles programs containing general, unbounded loops.
Text Representation through Multimodal Variational Autoencoder for One-Class Learning
Authors: Gôlo Marcos Paulo Silva , Marcacini Ricardo Marcondes
Published: June 2023

Multi-class learning (MCL) methods perform Automatic Text Classification (ATC), which requires labeling for all classes. MCL fails when there is no well-defined information about the classes and requires a great effort to label instances. One-Class Learning (OCL) can mitigate these limitations since the training only has instances from one class, reducing the labeling effort and making the ATC more appropriate for open-domain applications. However, OCL is more challenging due to the lack of counterexamples for model training, requiring more robust representations. However, most studies use unimodal representations, even though different domains contain other information that can be used as modalities. Thus, this study proposes the Multimodal Variational Autoencoder (MVAE) for OCL. MVAE is a multimodal method that learns a new representation from more than one modality, capturing the characteristics of the interest class in an adequate way. MVAE explores semantic, density, linguistic, and spatial information modalities. The main contributions are: (i) a multimodal method for ATC through OCL; (ii) MVAE for fake news detection; (iii) relevant reviews detection via MVAE; and (iv) sensing events through MVAE.
Dynamic allocation of microservices for virtual reality content delivery to provide quality of experience support in a fog computing architecture
Authors: Alencar Derian , Oliveira Helder , Rosário Denis
Published: June 2023

Virtual Reality (VR) content is gaining popularity and allowing users to immerse themselves in a new world over the Internet. However, the high-demand for resources and the low latency requirements of VR services require changes in the current 5G networks to deliver VR with quality assurance. Microservices present a suitable model for deploying services at different levels of a 5G fog computing architecture for managing traffic and providing Quality of Experience (QoE) guarantees to VR clients. However, finding the most suitable fog node to allocate microservices for VR clients in QoE-aware 5G scenarios is a difficult task. This article proposes a QoE VR-based mechanism for allocating microservice dynamically in 5G architectures, called Fog4VR. Fog4VR determines the optimal fog node to allocate the VR microservice based on delay, migration time, and resource utilization rate. This article also presents the INFORMER, an integer linear programming model aiming to find the optimal global solution for microservice allocation. Results obtained with INFORMER serve as a baseline to evaluate Fog4VR in different scenarios using a simulation environment. Results demonstrate the capabilities of Fog4VR compared to existing mechanisms in QoE, migration time, fairness index, and terms of cost.
