Automated Machine Learning (AutoML) is a research area that aims to help humans solve Machine Learning (ML) problems by automatically discovering good ML pipelines (algorithms and their hyperparameters for every stage of a machine learning process) for a given dataset. Since we have a combinatorial optimization problem for which it is impossible to evaluate all possible pipelines, most AutoML systems use a Genetic Algorithm (GA) or Bayesian Optimization (BO) to find a good solution. These systems usually evaluate the performance of the pipelines using the K-fold cross-validation method, for which the more pipelines are evaluated, the higher the chance of finding an overfitted solution. To avoid the aforementioned issue, we propose a system named Auto-ML System for Text Classification (ASTeC), that uses the Bootstrap Bias Corrected CV (BBC-CV) method to evaluate the performance of the pipelines. More specifically, the proposed system combines GA, BO, and BBC-CV to find a good ML pipeline for the text classification task. We evaluated our approach by comparing it with state-of-the-art systems: in the the Sentiment Analysis (SA) task, we compared our approach to TPOT (Tree-based Pipeline Optimization Tool) and Google Cloud AutoML service, and for the Intent Recognition (IR) task, we compared with TPOT and MLJAR AutoML. Concerning the data, we analysed seven public datasets from the SA domain and sixteen from the IR domain. Four out of those sixteen are composed by written English text, while all of the others are in Brazilian Portuguese. Statistical tests show that, in 21 out of 23 datasets, our system's performance is equivalent to or better than the others.

Authors: Abari Jaouad , Tekin Ahmet , Topsakal Vedat
Published: May 2023

Since the inception of cochlear implantation, there has already been a lot of research into improving its technological aspects, whereas the surgical placement has enjoyed a golden standard for a long time. Since the advent of robotic surgery, there has now also been the development of robot-assisted cochlear implant surgery. This chapter will discuss the opportunities and challenges that robotic-assisted and image-guided cochlear implantation faces. The required accuracy and sensitivity to not harm inner ear structures during electrode insertion is already at the limits of human dexterity. With electrode arrays becoming smaller in the future, the need for robotic accuracy and reliability will become necessary. Robotic-assisted cochlear implantation is seen as a minimally invasive way of doing cochlear implantation surgery with the potential of being the golden standard in the future. An atraumatic intracochlear electrode array placement ensures that the anatomy and physiology of the inner ear structures are preserved as much as possible, thus reducing the risk of losing the rest of the natural hearing levels of the patient. This could lead to a broadening of the indication, opening the door for patients that only experience a loss at the higher frequencies. It is a given fact that robotising surgical procedures will standardise surgical outcomes.

Authors: Mdlambuzi Thandile , Muchaonyerwa Pardon , Mbangi Awonke
Published: May 2023

Heavy metal contamination has increasingly become an environmental problem. While it is found in soils naturally through processes of weathering of parent materials, it is the anthropogenic activities that create the greatest threat. A study was conducted to investigate the vertical distribution of heavy metals in soils after over 50 years of sewage sludge application. Soil samples were collected at 10 cm intervals to a depth of 50 cm from five treated transects and a control. The soils were analyzed for zinc, copper, lead, nickel, cadmium, arsenic and chromium. The concentration of all the metals was higher in the treated soils compared to the control. The results were compared with two parameters: the total maximum thresholds (TMT) and maximum permissible limits (MPL). The TMT is the concentration of the metal beyond which the risk to the environment is unacceptable, while MPL is the concentration beyond which further waste disposal is prohibited. Zinc, chromium, lead and cadmium were above maximum permissible limits, in treated soils. High concentrations of all the metals, including Pb, and organic carbon were measured down to 40–50 cm depth. Only Cd (and Pb only in transect 2) was above the maximum permissible limits beyond the 20–30 cm depth.
Perspective Chapter: Negative Thermal Gradient Gas Chromatography
Authors: Rosenberg Erwin , Klampfl Bernhard , D. Müller Robert
Published: May 2023

Gas chromatography is typically operated in isothermal mode for optimum separation of a mixture of compounds with a narrow boiling point range, or in temperature-programmed mode, which strives to achieve a compromise between separation efficiency and time. Temperature gradients also keep the peak widths nearly constant over a wide range of retention times, enhancing the detectability of the later eluting peaks. In this chapter, the use of negative thermal gradients for gas chromatography (NTGGC) – for the sake of simplicity, subsequently only denoted as thermal gradient-gas chromatography, TGGC – shall be discussed. (N)TGGC is achieved by producing a stationary temperature gradient along the relatively short GC column in a proprietary experimental setup that allows cooling on one end of the column and heating on the other. The sample is injected into the hot end of the GC column, and analytes move towards the colder end of the column. Along their passage through the column, they are focused by the increasingly lower temperature of the stationary phase. This leads to a focusing of the peaks as they reach the cold column end. With appropriate temperature programming, very fast (sub-minute) chromatography with excellent resolution can be achieved on short GC columns. The present contribution will both discuss the theory behind this unusual, but highly performant mode of gas chromatographic separation, and also the hardware aspects of this technique. Relevant examples will be presented which highlight both the speed and the separation power by which (N)TGGC excels in comparison with regular temperature-programmed GC.
Distribution of Selenium in Soils and Human Health

Published: May 2023

Selenium (Se) is essential as well as a toxic element for humans and animals if it exceeds a certain limit. Soil selenium plays an important role through the food chain. Total selenium in world soils ranges from 0.125 to 0.3 mg kg−1 and varies with the soils’ nature. High and low selenium in soils also poses serious environmental and health risks. However, in addition to selenium’s overall quantity in soil, selenium reactivity, and bioavailability also depend on its chemical structure. The amount of available selenium in the soil varies depending on its oxidation state since selenium species include selenide (Se2−), elemental selenium (Se0), selenite (Seo32−), selenate (Seo42−). The pH, soil texture, amount of organic matter, and the presence of competing ions are the four most significant soil characteristics that affect Se availability. Similarly, selenium uptake and accumulation are influenced by the crop type whether it is an accumulator or not. The selenium environmental and health risk assessment is necessary to evaluate in soils with high selenium contents and crops with higher selenium uptake. Whereas in areas where selenium deficiency is observed or vulnerable to selenium, deficiency needs to be supplemented through Se inputs. The selenium deficiency and toxicity areas should be monitored carefully from a health perspective.

Published: May 2023

The surface functionalization of natural fibers, mainly using TiO2 films, shows a growing interest in its application as yarns in fabrics that require advanced properties, allowing the use of their excellent physical and chemical properties in the textile area. The DC magnetron sputtering technique is a potential method for depositing TiO2 films onto natural fibers, allowing for the creation of advanced and competitive properties compared to synthetic fibers. Different crystalline phases of TiO2 have been shown to be effective in photocatalytic applications. Reactive discharges like the Ar/O2 gas mixture can be used to deposit TiO2 films with desired characteristics, and controlling deposition parameters can further manipulate the properties of the coatings. Analytical techniques such as XRD, XPS, and SEM/EDS can be used to study the surface properties of TiO2 films. XRD determines crystal structure, XPS provides information on chemical composition, and SEM/EDS examines morphology and elemental composition.

Published: May 2023

Fuel-based vehicles are a significant source of greenhouse gas emissions in America. Electric vehicles (EVs) offer a potential solution to this problem as a cleaner transportation technology. However, to promote the use of EVs, it is crucial to establish a robust infrastructure of charging stations. This research utilized a multi-factor geospatial analysis to address the complex problem of establishing an optimal EV infrastructure. Several factors, such as land use, demographics, and employment centers, were individually analyzed to determine their suitability for EV charging stations. By considering both positive and negative impacts of these factors, we scored them using geospatial analysis to identify the optimal locations for installing charging stations.

Ion Beam Application to Nuclear Material Damage Assessment
Authors: Nana Andoh Collins
Published: May 2023

With a substantial rise in world temperature as a result of uncontrolled greenhouse gasses released, particularly by industrialized countries, the need for efficient and economical energy has been increasing, necessitating the addition of the energy mix of one that will not harm the environment. This has pushed the nuclear sector to develop more advanced nuclear power plant systems. Quality materials capable of withstanding extreme radiation doses, high temperatures, and occasionally harsh corrosive conditions are required. This has resulted in the examination of the current materials already in use by earlier generations of the reactor system to determine their usefulness in advanced ones that would be subjected to even tougher environmental conditions than before and also design new materials that are of such strength and abilities. Since it can be accurately regulated and less time-consuming, ion beam technology has been extensively used in accelerator facilities and computer simulations to analyze the radiation deterioration of these materials. This chapter shed further insight into the many applications of ion beam technology in the evaluation of nuclear material damage. Apart from irradiation damage assessment, it also provided some understanding of numerous areas in the nuclear sector where ion beam technology is used.

Published: May 2023

Plants are associated with complex microbiomes, and many of the microorganisms that reside on plant surfaces (epiphytes) or within plant tissues (endophytes) are beneficial for the host plant and improve plant growth or stress resistance by a variety of plant growth-promoting capabilities. The plant microbiome could serve as a tool box to design synthetic microbiomes to enhance plant growth and crop resiliency under stress or to integrate benefits of plant microbiomes as important traits into plant breeding programs. For legumes, the most important members of the plant microbiome are nitrogen (N)-fixing rhizobia and arbuscular mycorrhizal (AM) fungi. Legumes harbor rhizobia in specialized root nodules, in which the bacteria fix gaseous N from the atmosphere and transfer plant available forms of N to host. AM fungi play a key role for the uptake of nutrients such as phosphate and nitrogen and improve the resistance of plants against abiotic (e.g. drought, salinity, and heavy metals) and biotic (herbivores and pathogens) stresses. Both partners compete with these benefits for photosynthetically fixed carbon from the host. In this review, we will summarize our current understanding of these interactions and will also focus on cooperative or competitive interactions between these two root symbionts in tripartite interactions.

Authors: Khan Javid , Han Lei
Published: May 2023

Titanium dioxide (TiO2) is a versatile material used in a variety of applications, including photocatalysis, photovoltaics, sensing, and environmental remediation. The properties of TiO2 are influenced by its defect disorder, with oxygen vacancy (V0) being a prominent defect that has been widely studied. Defective TiO2 materials, particularly those containing V0 defects, are of interest for the development of next-generation semiconducting nanomaterials. Several methods, including high-temperature calcination, ion implantation, and chemical doping, are used to produce defective TiO2 with varying degrees of V0 defects. The properties of defective TiO2, including optical, electronic, and structural characteristics, are essential for determining the material’s suitability for various applications. Modification of the defect structure of TiO2 through doping with impurities can enhance the photocatalytic activity of the material. Researchers continue to investigate the impact of factors such as crystal structure and the presence of other defects on the properties of TiO2-based materials, further enhancing their potential for various applications. Overall, a deeper understanding of defect disorder and the development of production methods for defective TiO2 will play a crucial role in the design and production of next-generation semiconducting nanomaterials.

Background: Crohn’s disease is characterized by damage to the intestines, which can affect the gastrointestinal tract (from the mouth to the anus). The risks of Crohn’s disease appear to be linked to changes in the gut Macrobiota or disturbances in the mucosa and intestinal genetics. Objectives: We aimed to study the implication of appendectomy on the risk of the development of Crohn’s disease in the western Algeria population. Methods: It was a retrospective analytical study of 403 patients from 2007 to 2020 carried out at the level of general surgery departments and university hospitals in western Algeria. Results: Four hundred three CD patients were included in our study. Among them, 81 cases have undergone an appendectomy. The average age was 36.88 ± 12.47, and the most affected location was the ileocecal location with P = 0.001. However, no significant association was noted between appendectomy and CD phenotype. Most of them suffered from constipation (P < 0.0001), came from urban areas, and presented extra-intestinal manifestations (P < 0.0001). Treatment of the disease was often medical, while 68 cases of the 81 appendectomized patients underwent surgery. Early relapse of CD was also observed in appendectomized patients with P = 0.035. Moreover, many complications (anal fissures, anal fistula) were also noted but with no significant association. Conclusions: From our results, it appears that Crohn’s disease risk can be associated with a previous appendectomy and mainly manifested by ileocecal localization and constipation.
Anthropometric and Physiological Changes in Bodybuilders During the COVID Pandemic
Authors: Seifi Skishahr Farnaz , Nabilpour Maghsoud
Published: May 2023

Background: The COVID-19 pandemic infects athletes in different ways, and some ceased their training due to the pandemic. Many others reduced their workout due to the closure of sports venues, and some could continue their training as usual for a while. Objectives: The aims of this study can be divided into two categories: (1) Test the between-group effect of different levels of training over six weeks and (2) test the within-group changes regarding body composition and fitness levels. Methods: Thirty-six male bodybuilders (age = 24 - 33) with at least two years of training experience volunteered to participate. The athletes were divided into two groups, those who were healthy and continued their training program (CTR, n = 12), those who were healthy and ceased their training program (HWT, n = 12), and athletes who were infected and ceased their training program (INF, n = 12). The maximal muscle strength in a chest press and squat before and after weeks was measured in the participants. In addition, skinfolds were used to examine body composition changes over the six weeks. Pre-pandemic anthropometric and physiological parameters of these subjects were available from their clubs. Before athletes returned to exercise in training groups, cardiovascular symptoms such as chest pain, palpitations, dizziness, syncope, tachycardia, and respiratory symptoms such as cough, sneezing, sore throat, asthma, and bronchial hypersensitivity after infection were assessed and recorded. One-way analysis was used to compare pre-and post-parameters, and Tukey post-hoc tests were used to assess the significance. Results: Post-test results revealed bodybuilders infected with the COVID-19 virus had significantly greater weight and lean body mass losses than the other two groups. Also, their 1RM squat and chest press exercises decreased more (P < 0.005). Clinical manifestations of the disease showed a return to normal ranges following two weeks of training. Conclusions: Lack of training caused changes in body composition and upper- and lower-body muscle strength of bodybuilders. If the cessation of training coincided with the COVID-19 infection, the intensity of these changes was exacerbated. It is recommended that training of those who have recovered from the coronavirus should be closely monitored for at least two weeks so that medical interventions can be promptly provided if necessary.

Nanocomposites based Aquaponic Cropping System Design and Control for Agriculture Industry
Authors: Jothiprakash V.M , Sezhian M.Vetrivel
Published: May 2023

Aquaponics is the practice of growing plants without soil, and it combines hydroponics (growing plants in water) and recirculating aquaculture (raising fish) systems. Some of the water’s nutrients are lost during the recirculation process in an aquaculture system, but the plants in the system are able to clean the water by absorbing the nutrients. The increasing problem of food scarcity has prompted more creative approaches to urban farming. Aquaponics is a type of hydroponics that can be used to grow plants in an urban environment. However, in order to grow plants, a smart aquaponic system requires close monitoring, mechanization, and management. Implementing vision-based systems that incorporate algorithms that make use of machine learning to boost agricultural output is one promising way to put this theory into practice. To do this, we analyzed how well the approximations of Logistic Regression (LR), K-Nearest Neighbor (KNN), and Linear Support Vector Machine (L-SVM) performed. To do this, we used computer vision to extract features from images of celery grown in a computer-controlled aquaponics system and used those images as training data for the algorithms. In order to teach the algorithms, these pictures were taken. The backup systems and cross-validation checks for each method have been improved. CNN was shown to be the most successful method

WEB TV. CRITÈRES D’IDENTIFICATION ET CARACTÉRISTIQUES INTRINSÈQUES
Authors:   West University of Timișoara, Filimon-Benea Anamaria
Published: May 2023

Le ter me générique Web TV désigne la transmission du contenu vidéo et de la télévision en ligne. Contrairement à l'expression «WebRadio» qui définit une radio FM analogique (transmet 24h / 24 et dispose d'une grille de programme), diffusé en streaming sur Internet, le Web TV peut prendre plus ieurs formes. Nous allons prendre comme critère de base du WebTV: un site qui transmet des vidéos par streaming, mais ayant une logique éditoriale du point de vue du contenu. Ce contenu est obligatoirement réalisé par l’équipe de la Web TV, et non pas par des utilisateurs ou des internautes. Un contenu créé exclusivement pour le milieu en ligne qui n’est pas repris d’une télévision classique.
Dynamics Of Organizational Communications In Sharing Fantasy Themes To Maintain The Solidarity And Existence Of Community Organizations
Authors: Sinaga Lerman
Published: May 2023

The purpose of this study is to explain the organizational communication aspect of a community organization, Forum Betawi Rempug (FBR), and to reveal the interaction patterns and dynamics of various fantasies of dramatically exchanged symbols. Organizational communication can be defined as the process of creating and exchanging messages in a network of interdependent relationships to cope with an uncertain or changing environment. This research approach uses a subjectivist in the interpretive category. This study uses a qualitative method by using a Symbolic Convergence approach which is subjectivist. The results show that the dynamics of sharing fantasy patterns on the theme of leadership and Betawi figures of FBR community organization depart from the rhetorical vision of the issue of the revival of Betawi in the past, the era before the formation of the State and long before the Dutch colonial era existed. Betawi is a culture that is noble and needs to be fought for. In the organization’s context, FBR is a forum for the struggle to unite the Betawi people by evoking Betawi cultural values and the struggle for the Betawi people’s lives. From the narrative analysis of the FBR community organization, the present storytellers are the leaders in the ranks of the FBR. The latter is considered the primary source of information for delivering the message of the existing dramatic stories. The meaning of leadership in a metaphorical context often gives rise to stories of Betawi’s character and leadership as village guards in the sense of an essential struggle that contains sincerity and loyalty to the area where they live.
