Published: February 2023

Orientado pelas teorias pós-crítica do currículo, esse estudo objetiva compreender as torcidas organizadas como espaços formativos, que atuam na constituição de sujeitos torcedores. Trabalhando com um grupo chamado Movimento 105 Minutos, focalizamos as pedagogias presentes nas interações de seus membros, tomando-as como integrantes de um currículo cultural. Para tanto, foram feitas uma pesquisa bibliográfica, observações participantes e entrevistas semiestruturadas. Na produção dos dados, utilizamos a teoria do discurso de Michel Foucault. Como resultados, notamos um currículo que busca formar torcedores caracterizados pelo amor, apoio e fidelidade incondicional ao clube, aspectos manifestados tanto em falas, quanto em ações. Nesse sentido, os sujeitos adotam posturas ritualizadas, valendo-se de elementos materiais e simbólicos, a fim de formar uma identidade de grupo e transmitir seus modos de torcer.

Objective: It is well known that some data features (sample size, skewness, among others) may determine method performance. The choice of those features depends on the researcher’s level of awareness on the statistical method. In this study, the level of awareness on the influence of spatial data key characteristics (sample size, skewness, spatial dependency and variogram model) in Bayesian Maximum Entropy (BME) was analyzed. Methodology: A systematic review was conducted that covers the period from 1990 (year of BME introduction) to 2019. Two main keywords “Bayesian Maximum Entropy” and “BME” were used for literature search. Publications which only mentioned the keywords without applying BME were excluded while those with application and/or BME theory discussion were considered. Six of the world’s leading Open Access sources of scientific literature were considered, namely: Science Direct, African Journals Online, Springer, Google Scholar, MPDI and Academic Journals. A total of 118 research articles from 62 journals were identified. The sample sizes screened shows that 25.4% of the published articles used few samples (less than 100), which implies the variogram might not yield accurate results. The analysis of the use of skewness showed that most researchers do not apply transformation on skewed data (82.2%) nor consider skewness in their descriptive statistics (90.7%). Even though 11% of theoretical papers have mentioned about spatial dependency level, 92.4% of them failed to consider it. Most researchers (68.64%) do not specify the variogram models but when they do, they mostly use exponential model (12.7%). It clearly appears in this review that most researchers do not consider the effect of sample size, skewness, and spatial dependency level when applying BME. Yet very few research works have focused on these aspects. This therefore calls for more in-depth studies on the effect of data characteristics on BME’s performance. Keywords: Bayesian Maximum Entropy, sample size, skewness, spatial dependency.

Published: February 2023

Image classification is one of the studies that is currently being developed. The details of the characteristics that must be captured make researchers compete to find the most suitable method for classifying. The Convolutional Neural Network (CNN) algorithm is one of the most superior algorithms in the field of object classification and identification today. With the help of several packages contained in Google Colab for classification, this algorithm is easier to use. In this study, the target case is the age of a person who will be classified using photos or images taken from the internet which are then stored in the form of Google Drive. The research data used is divided into 2 parts, namely for training data as many as 23.440 images, and 10,046 for testing data. Then to facilitate the extraction of features from the features to be identified, the researchers carried out the preprocessing stage, namely grayscale images, and data augmentation. The purpose of this study is to implement the concept of Deep Learning with Convolutional Neural Networks (CNN) in image classification and to determine the level of accuracy of the CNN model in classifying images. After the algorithm is run and the model has been formed, an accuracy of 78.5% is obtained. It can be concluded that the Convolutional Neural Network (CNN) method is good at classifying images

This paper aimed at the detection of blackhole attacks and proposed a new method called as Secure and Light Weight Adhoc On demand Distance Vector Routing (SLW-AODV). SLW-AODV is an extended version of the traditional AODV routing protocol. The proposed SLW-AODV ensures resilience for both blackhole and cooperative blackhole attacks. It employs a simple Challenge, Response and Confirm (CRC) strategy with chaotic maps for the identification of both blackhole and cooperative blackhole attacks. SLW-AODV identifies the attacked nodes at both route discovery and data forwarding process. For experimental validation, we have conducted extensive simulations and the performance is validated through Packet Delivery Ratio, Throughput and Average end-to-end delay. The obtained performance metrics shows an outstanding performance than the state-of-the art methods.
A CMOS LIF neuron based on a charge-powered oscillator with time-domain threshold logic
Authors: Granizo Cuadrado Javier , Garvi Ruben , Garcia Diego , Hernandez Corporales Luis
Published: February 2023

This paper introduces a new CMOS implementation of a spiking Leaky Integrate-and-Fire (LIF) neuron. The circuit does not require any analog circuit block such as comparators or current sources thanks to the use of a ring-oscillator as an integrator and a phase delay detector as threshold logic. The circuit admits both excitatory and inhibitory input spiking signals whose pulse width does not affect the computation. Instead of powering the ring oscillators from a power supply, the input spikes charge a capacitor bank which powers the ring oscillator. The paper describes the operation of the neuron analytically for the input integration and the membrane voltage decay. Also, a circuit-level simulation in 65nm CMOS technology has been performed, achieving a power efficiency of <40fJ/spike.
Recursive Constrained Sine Second-Order Error Promoting Adaptive Algorithm
Authors: Li Yingsong
Published: February 2023

This brief proposes a recursive constrained sine second-order error promoting adaptive (RCSSOEPA) algorithm. Compared with classical recursive method, the RCSSOEPA algorithm can achieve better steady state performance in impulsive noise. In general, the sine second-order error (SSOE) is constructed to devise a new recursive constrained adaptive-filtering within the least-squares framework for solving linear constrained optimization problems. The mean-square (MS) stability of the RCSSOEPA and its theoretical instantaneous MS deviation under Gaussian and non Gaussian noise are analyzed, numerically investigated and discussed in detail. Simulated results are reported to give a comfirmation of the theoretical analysis, and show that the RCSSOEPA outperforms recent developed constrained adaptive filtering algorithms in the estimation misalignment and when used for system identification under impulsive-noise.
Joint Squared-Sine Function and ANM DOA Estimation for RIS-Based Sensing Systems
Authors: Li Yingsong
Published: February 2023

Reconfigurable intelligent surface (RIS) is an emerging technology for improving the performance of wireless communications. In this letter, a joint Squared-Sine function and atomic norm minimization (ANM), denoted as SS-ANM, is proposed for passive sensing assisted by RIS in wireless communication systems interfered by a wireless access point (AP). The proposed joint optimization is used to estimate the targets' direction-of-arrival (DOA), employing the spatial domain sparsity of the received signals. The optimal solution is achieved from the alternating direction method of multipliers (ADMM). With the help of the Squared-Sine function as the cost function, the proposed solution provides better estimation accuracy under various noises besides Gaussian noise, and meanwhile requires a lower computation complexity. Simulation results verify the superiority of the proposed joint minimization over existing DOA estimation methods.
VISTA: Fast and Efficient Traffic Surveillance by Tile Sampling

Published: February 2023

With the increasing number of vehicles in modern cities, traffic surveillance via cameras on roads has become an important application. Cities have installed thousands of cameras on roads, which send video feeds to a cloud center to run computer vision algorithms.  This requires high bandwidth. Current techniques reduce the bandwidth requirement by either sending a  limited number of frames/pixels/regions or relying on re-encoding the important parts of the video. This requires running DNNs to extract important portions in a frame so that they can be again sent at a higher resolution from the camera to the server.  This has the disadvantage of imposing significant overhead on the camera side compute, as re-encoding is known to be expensive, and makes the system less real-time.  In this work, we propose VISTA, a system that utilizes tile sampling, where a limited number of rectangular areas within the frames, known as tiles, are sent to the server. We then propose an adaptive tile sampling algorithm, that estimates the presence of moving objects by comparing the statistics of the tiles' bitrate (in kbps) and then decide to retain only the necessary tiles, thus eliminating the requirement to use a DNN at the camera side. We evaluate VISTA on different datasets having 56 videos in total to show that on average our technique reduces $17$-$40$\% of the total amount of data sent to the cloud while providing a detection accuracy of over $85\%$. Furthermore, VISTA also runs in real-time even on cheap edge devices like Raspberry Pi and nVidia Jetson Nano. Further, it requires minimal calibration compared to prior works.
Dual-Stream Attention-TCN for EMG Removal from a Single-Channel EEG
Authors: Lu Jun , Cai Ruihan , Guo Zhichao , Huang Weikun , Yang Qiyu
Published: February 2023

In this paper, guided by the prior knowledge that the overlap degrees of EEGs and EMGs vary across frequency bands, we propose a dual-stream temporal convolutional network (TCN) with attentions for EMG removal from single-channel EEG, called DSATCN. DSATCN consists of two groups of 1-D convolution-based encoder and decoder pairs and TCN-based separators. The first group extracts the reliable features of EEG recordings in a low-frequency band, which contains fewer EMG artifacts. The second group adaptively fuses these reliable features by the channel-attention network to improve the feature extraction and mask learning of the full frequency band EEG. Furthermore, regarding the diversity of latent EEG dependencies, we add the inception layers in TCNs to extract the multi-scale EEG features, employ multi-head self-attentions to gather global information in multi-levels, and use the channel-temporal wise dropout to improve the generalization performance. And we use two public datasets to evaluate the effectiveness of DSATCN, which are EEGdenoiseNet and BioSource EEG.
A Comparative Study of rPPG-Based Pulse Rate Tracking Algorithms for Fitness Activities
Authors: Zhu Qiang , Wong Chau-Wai , Lazri Zachary , Chen Mingliang , Wu Min , Fu Chang-Hong
Published: February 2023

Recent studies have shown that subtle changes in human face color due to heartbeats can be captured by regular RGB digital video cameras. It is possible, though challenging, to track one's pulse rate when a video contains significant subject's body motions in a fitness setting. The robustness gain in the recently proposed systems is often achieved by adding or changing certain modules in the system's pipeline. Most existing works, however, only evaluate the performance of the pulse rate estimation at the system level of particular pipeline configurations, whereas the contribution from each module remains unclear. To gain a better understanding of the performance at the module level and facilitate future research in explainable learning and artificial intelligence (AI) in physiological monitoring, this paper conducts an in-depth comparative study at the module level for video-based pulse rate tracking algorithms; a special focus is placed on challenging fitness scenarios involving significant movement. The representative efforts over the past decade in the field are reviewed, upon which a reconfigurable rPPG framework/pipeline is constructed comprising of major processing modules. For performance attribution, different candidates for each module are evaluated while having the rest of modules fixed. The performance evaluation is based on a signal quality metric and four pulse-rate estimation metrics and uses the simultaneously recorded ECG-based heart rate measurement as a reference. Experimental results using a challenging fitness dataset reveals the synergy between pulse color mapping and adaptive motion filtering in obtaining accurate pulse rate estimates. The results also suggest the importance of robust frequency tracking for accurate PR estimation in low signal-to-noise ratio fitness scenarios.

Published: February 2023

The rapidly changing software industry presents challenges in teaching software engineering concepts and skills, especially in the area of DevOps. This encompasses both technical aspects, such as pipeline automation, and non-technical ones, such as culture, principles, and team interaction modes. This presents a significant challenge and there is high demand for skilled DevOps practitioners.

To address these challenges, we propose a teaching strategy for DevOps that is based on real-world experiences from companies adopting DevOps and real projects. The strategy incorporates two teaching techniques: Research-based Teaching and Open Source Software projects.

Our findings can help educators effectively plan, implement, and evaluate DevOps courses. The results also highlight several opportunities for practitioners to benefit from academic environments and experiment with new ideas to train abilities expected in new hires.

Exploring Sweden and South Africa’s Responses to Mass Migration during the Period 2015–2019
Authors: Rugunanan Pragna , Meyers Celine
Published: February 2023

Sweden and South Africa are two major transnational destinations and attract large numbers of refugees and migrants, primarilydue to their ease of immigration policies. Besides their unique historical relations which can be traced back to as early as the 1890s, both countries continue to experience high volumes of mass migration and forced mobility which peaked in 2015. Following the so-called ‘Syrian refugee crisis’, Sweden witnessed the second largest asylum applications in Europe. At around the same time, South Africa experienced its highest backlog of asylum applications. It is against this backdrop of a long and diverse history of relations andongoing migration that we seek to engage with the responses of both countries to mass migration using a comparative approach. The article presents a historical perspective of migration between Sweden and South Africa and examines their ongoing migration policydebates. It concludes with an analysis of current political contestations and some key lessons for each country.

Nainital is a hill tourist place. It is famous for its natural beauty. Therefore, thousands of tourists from all over India and abroad come to visit this place. The environment of Nainital is fragile and sensitive, so it was intended to study the ambient air quality of the city. The present study includes the evaluation of ambient air quality and noise level. Ambient air monitoring has been conducted for suspended particulate matters, sulphur di-oxides and oxides of nitrogen at mall road (near Nagar Palika Library) and bus station (Tallital). The noise level monitoring was also conducted at different points of the city characterising commercial, residential area and silence zone. At other sites of silence zone, the values were usually beyond the prescribed limit. At all sites taken in commercial, areas, the values were beyond prescribed limit. The main sources of noise pollution in the city of Nainital is vehicular movements and the noise generated due to the use of horns of the vehicles. Similarly, the vehicular emissions are cause of air pollution. The SPM value at Nainital ranged from 88 to 366 mg/m3, sulphur dioxide remained in the range of 10.2 to 25mg/m3 and NO2 ranged between 13 and 86 mg/m3. The study revealed that the SPM and NO are beyond the limit prescribed for sensitive areas.

Published: February 2023

Environmental pathway analysis provides the link between qualification of source emissions and assessments of receptor exposure (eg. human exposure) through estimation of the ambient concentrations of contaminants in the various environmental media.Two basic techniques can be employed to investigate environmental pathways: analytic sampling programs & mathematical fate modelling. Sampling programs are costly to design & implement, therefore, computerized mathematical models of environmental processes are frequently used to generate information unavailable by other means or to estimate data (i.e. environmental conc.) that would otherwise be costly to obtain.

This community service aims to provide an understanding that universities and academics act as business incubators for developing small and medium enterprises. In order to support the growth and development of SMEs, there needs to be a synergy from various parties ranging from academia, industry, and universities as stakeholders. The business incubator is a place used by many developing countries, including Indonesia, as a means of developing new businesses and/or small and medium enterprises (SMEs). The business incubator itself is an institution that oversees a business incubation in the coaching process for small businesses and/or new product development as well as the provision of business facilities and infrastructure, business development, and management and technology support. The availability of skilled labor needed by the Business and Work World (DUKA) is still very low. This is revealed from data from the Central Statistics Agency (BPS) which was announced in February 2020, which was around 13%. This condition is a challenge for universities not to exacerbate this condition by introducing an early work environment to students, so that theycan become graduates according to the needs of the job market, either as employees or business owners through student business incubators at universities. The Business Incubator is a form of Academic Entrepreneurship adapted to the industrial era 4.0 based on the use of electronic media and the internet. To socialize the community service material to SME business actors, the lecture method and question-and-answer method are used for 90 minutes. The results of the socialization have further increased the understanding of the community and SMEs about the importance of developing business incubators as business facilities and infrastructure in business development

West Sigodang Nagori, Panei District, Simalungun Regency, is a nagori whose main livelihood is agriculture. Planting is done on mering land. The existing dry land is planted with food crops such as upland rice and corn, various vegetable crops, plantation crops including coffee, oranges, cocoa etc. Upland rice is a plant that is widely cultivated, the results are for their own needs. Upland rice planted are local varieties such as red sigambiri, white sigambiri, sipala, sironip and the others. Generally varieties have weaknesses such as deep age, low production, easy to fall and other weaknesses. The presence of a new upland rice variety called Inpago is a breakthrough that gives hope for increasing upland rice production. There are many varieties of Inpago that have been released to farmers for planting. From the results of several studies show that Inpago production is quite high. In addition, several Inpago varieties have adapted to land in the low to medium lands so that the distribution of their plantings has become more widespread. The pilot project (Demplot) held in West Sigodang Nagori is a way to introduce several Inpago varieties that have an agro-ecosystem that fits the nagori. In order to provide information about the growth and production of Inpago that is tested, several farmers are included in their cultivation and at harvest time, apart from farmers, local agricultural extension workers are also invited. Based on the yields, the farmers are interested in planting the Inpago Agritan variety and the seeds to be planted from the harvests of this pilot plot.

Встановлено, що за проведення позакореневого підживлення мікродобривами у фазі інтенсивного росту й розвитку рослин та, можливо, на початку бутонізації на тлі передпосівного внесення мінеральних добрив тривалість міжфазного періоду нуту від повних сходів до повної стиглості зерна коливалася в межах 89–95 діб, або збільшилася на 4–6 діб порівняно з контролем за нерівномірного вологозабезпечення та зміни температурного режиму в період вегетації. Таким чином, позакореневе внесення бору та молібдену підвищувало енергію проростання насіння нуту і його схожість, а також сприяло збереженню рослин у комплексі з позакореневим підживленням упродовж усього періоду вегетації порівняно з контролем без передпосівного внесення мінеральних добрив.

На території Степу і Лісостепу України, зокрема Лісостепу Правобережного, однією з найбільш рентабельних серед зернобобових культур є соя, яка має великий попит на внутрішньому та світовому ринках. Тому оптимізація технології вирощування сої з урахуванням біологічних вимог адаптованого сорту є актуальною науковою проблемою, вирішення якої дасть можливість підвищити продуктивність культури та ефективність її вирощування. За результатами наших досліджень розроблено сучасну модель технології вирощування нових сортів сої Аратта і Софія, яка відповідає їх біологічним вимогам та дає можливість максимально реалізувати врожайний потенціал цих сортів, підвищити якість насіння, зменшити витрати матеріальних ресурсів. Визначено нові варіанти високоефективного використання соєю природних ресурсів – води, сонячної енергії та поживних речовин ґрунту. Рекомендовано виробництву оптимальні норми висіву насіння для сортів сої нового покоління, на різних фонах живлення, застосування мінеральних і бактеріальних добрив для цих сортів та високоефективні регулятори росту рослин, що дає можливість одержувати врожайність насіння в межах 3,0-3,5 т/га, підвищити його якість та зменшити технологічні витрати на 10-12% порівняно з базовою технологією. Рекомендована технологія пройшла виробничу перевірку в господарствах Хмельницької, Чернівецької та Тернопільської областей. У даній роботі викладено результати досліджень впливу мінеральних і бактеріальних добрив, норм висіву насіння та регуляторів росту на формування вегетативної маси, репродуктивних органів та продуктивність інтенсивних сортів сої Аратта і Софія.

Os compostos bioativos despertam compostos bioativos que despertam grande interesse das indústrias farmacêuticas, alimentícias, agrícolas e outras. Produzidos em grande parte por microrganismos e plantas apresentam aplicações terapêuticas como agentes antimicrobianos, imunossupressores, anticancerígenos e anti-inflamatórias. Conhecidos como Produtos Naturais (PNs) são classificados como pequenas moléculas, representadas pelos metabolitos microbianos, moléculas sinalizadoras, fatores de crescimento entre outros. Geralmente, os PNs já estudados são derivados da síntese de metabólitos secundários dos microrganismos e plantas (DEMAIN, 2000; DHAKAL; DHAKAL; SOHNG, 2017). Além dos PNs, diversos produtos farmacêuticos biológicos, denominados biofármacos são produzidos utilizando a tecnologia do DNA recombinante em plataformas de células de animais, vegetais e microrganismos (TRIPATHI; SHRIVASTAVA, 2019). Desde a sua introdução nos tratamentos clínicos em 1982, os medicamentos biofarmacêuticos revolucionaram o tratamento de doenças como câncer, distúrbios metabólicos e infecções. Como exemplos de biofármacos apresentam-se a produção de anticorpos monoclonais, interferons, citocinas, vacinas, moduladores de enzimas (LACANÁ; AMUR; MUMMANNENI; ZHAO et al., 2007; MICHAEL, 2015). O mercado biofarmacêutico se desenvolveu muito mais rápido do que o mercado de PNs e medicamentos sintéticos, devido ao envelhecimento da população. Objetivo: referenciar as principais plataformas microbianas de produção de biofármacos. Método: o trabalho envolve uma pesquisa descritiva por coleta de dados bibliográficos. Resultados: apresentação de sistemas procarióticos, principalmente Escherichia coli, sistemas eucarióticos de leveduras, Saccharomyces cerevisiae e Pichia pastoris e atividade biológica provenientes dessas plataformas. Conclusão: as plataformas microbianas devem se tornar primordiais no processo de produção de biofármacos, devido ao interesse das indústrias farmacêuticas e aplicação em terapêuticas.

A resistência aos antibióticos é um grave problema de saúde pública. Adicionalmente, o uso de antibióticos para tratamento de pacientes com COVID-19 aumentou a incidência de bactérias multirresistentes (MDR), agravando o problema de escassez global de antibióticos. Neste cenário, fontes não convencionais como os anfíbios têm surgido como uma nova fonte de peptídeos e probióticos. Sendo que a pele é a primeira linha de defesa contra patógenos, os peptídeos antimicrobianos (PAMs) presentes nas secreções cutâneas e bactérias cutâneas produtoras de metabólitos (BPMs) fornecem compostos com potencial atividade antimicrobiana. Esta revisão apresenta o potencial dos PAMs e dos BPMs contra bactérias patogênicas de interesse clínico, assim como sua atividade sinérgica em combinação com os antibióticos comercialmente disponíveis. Evidências elucidaram que os PAMs apresentam atividade antimicrobiana contra isolados clínicos, porém são limitados na sua aplicação farmacológica devido à toxicidade. Por outro lado, os BPMs têm se mostrado promissores na inibição de patógenos, entretanto seu espectro de ação é reduzido. O estudo de anfíbios demonstra ser promissor na busca de novos antibióticos, assim como também para potencializar o efeito terapêutico dos antibióticos disponíveis. Estes fatos são relevantes no Brasil, o país com maior diversidade de anfíbios no mundo.
