Sets with constant normal in Carnot groups: properties and examples
Authors: Bellettini Costante , Le Donne Enrico
Published: March 2021

We analyze subsets of Carnot groups that have intrinsic constant normal, as they appear in the blowup study of sets that have finite subRiemannian perimeter. The purpose of this paper is threefold. First, we prove some mild regularity and structural results in arbitrary Carnot groups. Namely, we show that for every constant-normal set in a Carnot group its subRiemannian-Lebesgue representative is regularly open, contractible, and its topological boundary coincides with the reduced boundary and with the measure-theoretic boundary. We infer these properties from a metric cone property. Such a cone will be a semisubgroup with nonempty interior that is canonically associated with the normal direction. We characterize the constant-normal sets exactly as those that are arbitrary unions of translations of such semisubgroups. Second, making use of such a characterization, we provide some pathological examples in the specific case of the free-Carnot group of step 3 and rank 2. Namely, we construct a constant normal set that, with respect to any Riemannian metric, is not of locally finite perimeter; we also construct an example with non-unique intrinsic blowup at some point, showing that it has different upper and lower subRiemannian density at the origin. Third, we show that in Carnot groups of step 4 or less, every constant-normal set is intrinsically rectifiable, in the sense of Franchi, Serapioni, and Serra Cassano.
Removing Artifacts From Eeg Signal Using Wavelet Transform and Conventional Filters
Authors: Felja Meryem , Bencheqroune Asmae , Karim Mohammed , Bennis Ghita
Published: March 2021

Electroencephalogram (EEG) is a signal of an electrical nature reflecting the neuronal activities of the brain. It is used for the diagnosis of certain cerebral pathologies. However, it becomes more difficult to identify and analyze it when it is corrupted by artifacts of non-cerebral origin such as eye movements, cardiac activities ..., therefore, it is essential to remove these parasitic signals. In literature, there are different techniques for removing artifacts. This paper proposes and discusses a new EEG de-noising technique, based on a combination of wavelet transforms and conventional filters. The results of the proposed method are evaluated using three common criteria: signal-to-noise-ratio (SNR), mean square error (MSE) and cross correletion function (CCF). These experimental results demonstrate that the proposed approach can be an effective tool for removing artifact without suppression of any signal components.

Published: March 2021

The novel Covid-19 pandemic has caused disruption of several activities globally. It has resulted in lockdown of economic activities in most countries including Nigeria. The effects of the pandemic and the associated lockdown on the mental health status of Nigerian students have not taken into perspective in the control efforts.

This study was conducted to assess the burden of the psychological problems associated with COVID-19 pandemic and coping strategies among students at Bowen University, Iwo (BUI), Nigeria. A cross-sectional survey was conducted, and multi-stage sampling technique employed to recruit 433 eligible respondents. Validated online self-administered, semi-structured questionnaire was used to collect relevant information from respondents. Appropriate summary statistics were carried out, and Binary logistic regression model was developed to examine protective/risk-factors of decreased mental wellbeing among the respondents. Mean age of the respondents was 20.11 ± 2.9 years, almost three-quarter (72.7%) of them were females. In all, 55.0% of the respondents had decreased psychological wellbeing because of the lockdown. Protective factors against decreased mental wellbeing included online catting with friends/watching films (OR=0.22, 95%CI=1.37-3.59), and participating in online vocational training (OR=0.25, 95%CI=0.25-0.61). The odds of decreased mental wellbeing was significantly higher in students who indicated a need for substance use as coping strategy(OR=1.50, 95%CI=0.55-4.05), and those who were not satisfied with online teaching method (OR=5.34, 95%CI=4.13-9.18).The mental health impacts of COVID-19 on the Nigerian students is huge. Thus, psychological wellbeing of the Nigerian students should be taken into cognizance and prioritized in the post-COVID-19 national rebuilding strategies.

Published: March 2021

"Hyperglycaemia upon admission is a pathophysiological response to acute brain ischemia that has been independently associated with high mortality rate and poor prognosis. Glycaemic variability (GV) has also shown association with poor clinical outcomes among stroke patients. GV is best assessed by continuous glucose monitoring (CGM), which enables consecutives glucose measurements every 5 minutes. This pilot study aimed: 1) To describe safety, feasibility and tolerability of CGM in the acute stroke setting; and 2) To compare CGM and conventional FS glucose-based monitoring regimen in terms of their relationship with GUA and the accuracy of hypoglycaemic episodes detection. Safety, feasibility and tolerability of CGM was excellent in our cohort of 23 patients with acute stroke (61% ischemic and 39% intracerebral haemorrhage) and there were no adverse events. CGM recorded ten hypoglycaemic episodes that were not detected by conventional FS monitoring. GUA was associated with coefficient of variation (CV) of CGM (p=0.03), CV of FS (p=0.01), standard deviation (SD) of CGM (p-value=0.01) and mean amplitude of glucose excursions (MAGE) (pvalue= 0.001)."
Lessons learned about language learning and extended reality frameworks
Authors: Iacono Saverio , Vercelli Gianni
Published: March 2021

"The knowledge of a second language is an obligation in educational systems of the European Community for many years and the quality of teaching and learning, especially in Italy, could be largely improved for a better outcome. Methods like Game-based Learning and Gamification could improve and change this outcome, combined with new tools used as educational technology in an immersive context. This paper presents some lessons learned from the adoption of VR / AR within two applications related to language learning. In this context, being immersed in an engaging and fun simulated situation is a good way to practice language conversations. In the last few years the great clamor of new VR / AR devices (HMD, controller, tracker) promotes the creation of new frameworks of extended reality for language learning."
Intelligent navigation of linked data with a graphical interface based on semantic similarity
Authors: Fonseca-Ortiz Pedro , Ceballos Hector G.
Published: March 2021

"Semantic Web Technology proposes the use of linked data and ontologies as a mean for providing meaning to information. Even though several tools for the analysis and visualization of linked data exist, these tools require a lot of specialized knowledge to fulfill a purpose. Additionally, this complexity hardens its use for nonexperienced users therefore limiting semantic web applications. This paper describes a tool that combines the use of a recommendation system and an intuitive dynamic user interface for navigating linked data. The tool guides the user to find resources of interest by highlighting those related to his search intention. This is, the platform learns on the fly the user interest and makes recommendations based on the connections between resources."

Authors: Verbicaro Soares Douglas , Govêia de Oliveira Maria Clara
Published: March 2021

Este trabalho tem o objetivo de evidenciar o histórico da regulamentação da atividade da pesca no Brasil. Exemplificações essas previstas na hierarquia normativa da Constituição Federal de 1988 e demais orientações infraconstitucionais, como leis e decretos que auxiliaram nas previsões sobre a pesca no âmbito nacional e regional do Estado do Pará. Propõe-se a ideia de existência de diversos instrumentos reguladoras da pesca ao longo dos tempos, mas sua eficácia colide com preceitos basilares da proteção e respeito ao Meio Ambiente e na manutenção da vida animal, na tentativa de conciliação entre as atividades humanas quem envolvem os tipos de pesca. Assinala-se as prováveis implicações que uma perspectiva legal pode ter nas relações humanas e nas atividades decorrentes do sustento e exploração econômica da atividade pesqueira. Conclui-se que uma visão multidisciplinar sobre a problemática que engloba a atividade da pesca e o direito pode ser importante para ressaltar os pontos controvertidos que envolvem a matéria, bem como para indicar caminhos reais para garantir a sensibilização sobre proteção ambiental, desenvolvimento pesqueiro e Direitos Humanos no país.

ABAA CASE STUDY: JOURNEY OF THE VEILED ENTREPRENEUR
Authors:   IBA, Karachi, Qureshi Shahid
Published: March 2021

The case describes the entrepreneurial journey of a passionate and dedicated young female entrepreneur, Hareem Zahid. She is a 2016 graduate from Institute of Business Administration (IBA), where she completed her bachelor’s degree in BBA Entrepreneurship. Her journey reflects that how she entered into the Entrepreneurship program at IBA, and the sequence of events led her to the frivolous pursuit of starting an online venture of ABAA. The venture came into being in January 2013, and climbed the ladder of success in a span of almost 2 years. ABAA’s philosophy is to help the modest women find refined elegance, versatility and style in their modest wardrobe, with no compromise on quality and affordability of price. This case elaborates the journey embarked upon by Hareem, who set foot in this venture with a spiritual orientation, where rather than pursuing things with a fiercely competitive mindset, she developed a mindset which seeks the pleasure of Almighty Allah (swt), with a belief of cooperation and customer service. The story of ABAA depicts that a high spiritual orientation along with an entrepreneurial mindset led Hareem to do something which creates real value and helps her to live a meaningful life. The case further examines the vision Hareem had of expanding her business and taking it to the next level. The case is extremely pertinent because of the dearth of literature available on female entrepreneurs in Pakistan. It aims to shed light on the mushroom growth of the women-led online business sphere in Pakistan.

Published: March 2021

Newly introduced scientometric indices have gained much popularity and have been widely discussed. The application of such indices and their validity for Research Performance Evaluation (RPE) focuses on various contexts and aggregate levels. Several methodological concerns have been raised regarding the application of these indices for RPE purpose. This study aims at describing the methodological issues faced and lessons learned from the investigations carried out on engineering research data in Malaysia, using the scientometric approach at meso and micro levels. This scientometric case study employed a set of newly introduced RPE indices along with traditional metrics. The unit of analysis was Malaysian engineering research. At meso level, twelve Malaysian universities were selected. While, at the micro level, a hundred most productive Malaysian related researchers were chosen. The data were retrieved from Web of Science (WoS) for the duration of ten years (2001-2010) and limited to nine WoS engineering categories only. This study enlightens the issues and suggests the possible measures that should be taken into account while conducting the empirical studies by applying scientometric approach to RPE.

Authors: Mohammed Shivan H. M. , Çinar Ahmet
Published: March 2021

One of the most common malignant tumors in the world today is lung cancer, and it is the primary cause of death from cancer. With the continuous advancement of urbanization and industrialization, the problem of air pollution has become more and more serious. The best treatment period for lung cancer is the early stage. However, the early stage of lung cancer often does not have any clinical symptoms and is difficult to be found. In this paper, lung nodule classification has been performed; the data have used of CT image is SPIE AAPM-Lung. In recent years, deep learning (DL) was a popular approach to the classification process. One of the DL approaches that have used is Transfer Learning (TL) to eliminate training costs from scratch and to train for deep learning with small training data. Nowadays, researchers have been trying various deep learning techniques to improve the efficiency of CAD (computer-aided system) with computed tomography in lung cancer screening. In this work, we implemented pre-trained CNN include: AlexNet, ResNet18, Googlenet, and ResNet50 models. These networks are used for training the network and CT image classification. CNN and TL are used to achieve high performance resulting and specify lung cancer detection on CT images. The evaluation of models is calculated by some matrices such as confusion matrix, precision, recall, specificity, and f1-score.

Authors: Fresnoza-Flot Asuncion , Nagasaka Itaru , Costa Bruno Botelho
Published: March 2021

A migração familiar filipina resulta em muitas crianças “deixadas para trás” aos cuidados de parentes, mas reunificações familiares subsequentes podem disparar ajustes emocionais na díade criança-cuidador(a). Partindo de trabalhos de campo etnográficos realizados na França, na Itália e nas Filipinas, este artigo visa lançar luz sobre essas mudanças. Examinando casos de migrantes da geração 1.5 na França e na Itália e seus parentes cuidadores que permaneceram nas Filipinas, este artigo descortina a natureza mutável e flexível dos cuidados infantis em famílias transnacionais filipinas e as dificuldades emocionais interligadas entre cuidadores, crianças e pais. A despeito destas, a relação cuidador(a)-criança perdura para além de fronteiras, ao mesmo tempo em que migrantes da geração 1.5 reconhecem os esforços de seus pais e cuidadores.
Training Foreign Militaries for Peace – U.S. IMET and Militarized Interstate Disputes 1976-2007
Authors: Fabian Sandor
Published: March 2021

How do U.S. International Military Education and Training programs affect the recipient states` behavior in militarized interstate disputes? While the relationship between U.S. military aid in the form of arms and equipment transfer and MID involvement has been studied extensively in international relations literature the effects of U.S. IMET programs on the same phenomena has been largely ignored. This study intends to fill some of this gap. This paper proposes that American educated and trained foreign military personnel return home with a better understanding about the role of the military as an instrument of national power, civil-military relations, and the cost of war. These military personnel advise their political masters against the use of military force during international disputes leading to a decreased probability of both MID initiation and escalation. To test this argument the analysis employs a merged dataset from the Correlates of War Projects and the most prominent U.S. IMET and coups data. Using logistic regression analysis this study finds that more U.S. IMET support a country receives the less likely it initiates MIDs. The analysis also finds that countries that receive U.S. IMET support are less likely to escalate ongoing MIDs to higher levels of hostility.

Research on Noise Reduction and Enhancement Algorithm of Girth Weld Image
Authors: Zhang Xiang-Song , Gao Wei-Xin , Zhu Shi-Ling
Published: March 2021

In order to eliminate the salt pepper and Gaussian mixed noise in X-ray weld image, the extreme value characteristics of salt and pepper noise are used to separate the mixed noise, and the non local mean filtering algorithm is used to denoise it. Because the smoothness of the exponential weighted kernel function is too large, it is easy to cause the image details fuzzy, so the cosine coefficient based on the function is adopted. An improved non local mean image denoising algorithm is designed by using weighted Gaussian kernel function. The experimental results show that the new algorithm reduces the noise and retains the details of the original image, and the peak signal-to-noise ratio is increased by 1.5 dB. An adaptive salt and pepper noise elimination algorithm is proposed, which can automatically adjust the filtering window to identify the noise probability. Firstly, the median filter is applied to the image, and the filtering results are compared with the pre filtering results to get the noise points. Then the weighted average of the middle three groups of data under each filtering window is used to estimate the image noise probability. Before filtering, the obvious noise points are removed by threshold method, and then the central pixel is estimated by the reciprocal square of the distance from the center pixel of the window. Finally, according to Takagi Sugeno (T-S) fuzzy rules, the output estimates of different models are fused by using noise probability. Experimental results show that the algorithm has the ability of automatic noise estimation and adaptive window adjustment. After filtering, the standard mean square deviation can be reduced by more than 20%, and the speed can be increased more than twice. In the enhancement part, a nonlinear image enhancement method is proposed, which can adjust the parameters adaptively and enhance the weld area automatically instead of the background area. The enhancement effect achieves the best personal visual effect. Compared with the traditional method, the enhancement effect is better and more in line with the needs of industrial field.

Air pollution can be interpreted as the presence of foreign substance or level substance contained in the air, so that it can cause changes in the composition of the air from normal conditions. The presence of pollutants sourced from moving and immovable sources can be in the form of dust particles that can affect the level of air quality in the environment and interfere with human health, so that air quality is measured. The measurement of air quality particulates carried out aims to determine the quality of outdoor air at PSDKU Airlangga University in Banyuwangi. This type of research is descriptive observational research. The method used in sampling is purposive sampling. This research was conducted in 5 locations, namely Sobo basketball court, student parking lot, outdoor student discussion area I, Sobo campus outdoor canteen, and outdoor student discussion area II. The result of measurements of dust particulate levels showed that all places were in the good category, but the student parking lot had the highest average which is equal to 1,572 µ/m3, compared to the other 4 places. Efforts that can be made to overcome the high levels of dust particulates in PSDKU Airlangga University in Banyuwangi include reducing the use of motorized vehicles, as well as always covering the helmet and wearing masks when driving, as well as care free day policies in the campus area.
Türkiye’ye Göçün Değişen Zamansal ve Mekânsal Örüntüleri

XX. Yüzyılın sonuna doğru küresel göçün karakteristiklerinde yaşanan bazı değişimler Türkiye için de gözlenmeye başlamış ve XXI. yüzyılın başından itibaren ise daha da belirginleşmiştir. 1980’den itibaren Türkiye’ye gelen göçün niceliği ve niteliği yanında hem kaynak sahaları hem de ülke içindeki mekânsal örüntüleri de değişmeye başlamıştır. Bu araştırma, Türkiye’ye olan uluslararası göçün son 40 yıldaki kaynak sahasının değişen mekânsal örüntülerini mevcut göç verileri üzerinden belirlemeyi amaçlamaktadır. Göçün kaynak sahalarındaki değişimin dışında vatandaş-yabancı ayrımındaki değişen profiline de değinilen araştırmada mevcut verilerin sınırlılığına rağmen bazı sonuçlara erişilmiştir. Araştırmanın en temel bulgusu, Türkiye’ye gelen göçün vatandaştan yabancıya doğru profilindeki değişimin yanı sıra bölgeselden küresele genişleyen bir mekânsal örüntüye sahip olduğudur. Mekânsal örüntüdeki bu değişim göç sistemleri kuramı içerisinde tartışılmıştır. Sonuçta, uluslararası göçün giderek genişleyen coğrafyası Türkiye’nin birden fazla bölgesel göç sistemine eklemlenmesine yol açmıştır.
Rainfall retrieval algorithm for commercial microwave links:
stochastic calibration

Abstract. During the last decade, rainfall monitoring using signal level data from commercial microwave links (CMLs) in cellular communication networks has been proposed as a complementary way to estimate rainfall for large areas. Path-averaged rainfall is retrieved between the transmitting and receiving cellular antenna of a CML. One rainfall estimation algorithm for CMLs is RAINLINK, which has been employed in different regions (e.g., Brazil, Italy, the Netherlands, and Pakistan) with satisfactory results. However, the RAINLINK parameters have been calibrated for a unique optimum solution, which is inconsistent with the fact that multiple similar or equivalent solutions may exist due to uncertainties in algorithm structure, input data, and parameters. Here, we show how CML rainfall estimates can be improved by calibrating all parameters of the algorithm systematically and simultaneously with the stochastic optimization method Particle Swarm Optimisation, which is used for the numerical maximization of the objective function. An open dataset of approximately 2,800 sub-links of minimum and maximum received signal levels over 15-minute intervals covering the Netherlands (~35,500 km2) is employed, where 12 days are used for calibration and 3 months for validation. A gauge-adjusted radar rainfall dataset is utilized as reference. Verification of path-average daily rainfall shows a reasonable improvement for the stochastically calibrated parameters with respect to RAINLINK's default parameter settings. Results further improve when averaged over the Netherlands. Moreover, the method provides a better underpinning of the chosen parameter values and is therefore of general interest for calibration of RAINLINK's parameters for other climates and cellular communication networks.

Abstract. The Qinghai-Tibetan Plateau (QTP), the largest high-altitude and low-latitude permafrost zone in the world, has experienced rapid permafrost degradation in recent decades, and one of the most remarkable resulting characteristics is the formation of thermokarst lakes. Such lakes have attracted significant attention because of their ability to regulate carbon cycle, water, and energy fluxes. However, the distribution of thermokarst lakes in this area remains largely unknown, hindering our understanding of the response of permafrost and its carbon feedback to climate change. Here, based on the Google Earth Engine platform, we examined the modern distribution (2018) of thermokarst lakes on the QTP using Sentinel-2A data; for the first time providing the true spatial distribution by using a resolution of 10 m with a relative error of 0–0.5. Results show that the total thermokarst lake area on the QTP is 1730.34 m2 km2, accounting for approximately 4 % of the total water area of lakes and ponds, and that overall thermokarst lake density is 12/100 m2 km2. More specifically, the densities of thermokarst lakes in the land types of alpine desert steppe (16/100 km2) and barren land (17/100 km2) were larger than those of alpine meadows (13/100 km2), alpine steppe (11/100 km2), and wet meadow (11/100 km2). These findings provide a scientific foundation for future investigations into the effects of climate change on the permafrost environment and carbon emissions from rapidly developing thermokarst landscapes.
