COMPUTER VISION FOR SKIN CANCER DETECTION AND DIAGNOSIS
Authors: Kaur Kamalpreet , Boddu Lakshman , Fiaidhi Jinan
Published: April 2020

Skin-cancer is the most common type of cancer among all other types of cancers spreading both developed and developing countries. In this paper, a web service is developed in order to help physicians as well as individuals to upload an image and diagnose the particular types of lesions. Computer vision is used to analyse lesions on images by providing computers with somewhat similarity as humans do. For this a Convolution Neural Network (CNN) is used with multi classification on International Skin Imaging Collaboration (ISIC) 2018 dataset with HAM10000 images. This dataset is a meta-data which has various types of images with seven different labels. At first, the model is trained with a larger training set and saved in a zip folder. Secondly, a web service is created where users or a doctor can upload an image for classification. Thirdly, the images uploaded are pre-processed as there is noise, hairs on image. Techniques like resizing, normalisation, thresholding, black-hat filtering and inpainting are used for this purpose. After this, the saved model is called to define whether the uploaded image is benign or malignant. The experimental results reveal that the proposed model is superior in terms of detection and diagnosis accuracy as compared to modern methods.

Published: April 2020

The influence of microbial preparations (MP) on the growth and condition of apple ( Malus domestica Borkh.) seedlings and the nutrition elements regime of the soil in the fruit nursery in two cultivars: Golden Delicious and Rennet Simirenko on the stock EM-IX have been studied. It was established that the applied MPs had a positive effect on the growth, condition of the rootstocks, the survival rate of the graft eyes and the degree of their winter hardiness. The stimulating influence of MP on the growth and yield of grafted apple seedlings has been established. Nutritional conditions improved and the content of mobile forms of element nutrition increases in the rhizosphere of seedlings. The individual reaction of the cultivar to interaction with the introduced bacteria is shown.
Influence of the natural and climatic factors on variation in a crown shape, mechanical resistance and an accident rate of woody plants on the example of Juniperus virginiana L
Authors: Kornienko V. O.
Published: April 2020

It has been experimentally found that the mono groups of Juniperus virginiana L. have less resistance to the natural and climatic factors, this is firstly due to increase in the height of biomass of the tree and secondly to application of loads in the form of a wind force, as well as an additional mass in precipitation. According to the results of diagnostics of the state and monitoring of sustainability of Juniperus virginiana L.plantings, the accident risk is estimated at 14% of the total number (585 units).
Working on Health Optimization: A Major Goal for Health Maintenance
Authors: IMB David
Published: April 2020

Some years ago – let’s say, for sure, some decades ago – a “good physician” was considered the one who would request a few laboratory tests to some patient and they would come out all altered. – Yes – one would say – he got it right to the point, disease concerning. However, in the 21st century, when we have moved the focus of preventive care from prevention of diseases to health maintenance, we believe that the “good physician” may be considered the one that aims at keeping all the test results basically normal. Actually, more than that: optimal. In fact, keeping the eyes on optimal test results is a major goal for Age Management practitioners. For that, even if we still have the established reference ranges, we’ve got to have our own interpretation of the tests we are used to from a different, more detailed standpoint than in the general practice. Some normal results must be seen as subnormal, which are, indeed, still different from abnormal. Some results may also be considered critical – that is, those ones which demand some urgent and immediate action.

Authors: Karras Beverley , Selvaraj Saumya , McConnell Athena , Andres Deirdre , Trinder Krista , McKague Meredith
Published: April 2020

Background: Pediatric clinical skills teaching sessions provide an early opportunity for students to be exposed to the medical care of children. This report describes second and third year medical students’ perceptions of and attitudes towards working with children before and after the pediatric clinical skills teaching sessions, and the experiences of those students precepted by pediatricians only compared to those students working with a combination of pediatricians and family physicians.Method: A 13 question survey was voluntarily completed before and after teaching sessions.  Written reflective assignments were qualitatively analyzed for key themes. Response rate averaged 68% with class sizes of 84 and 85 students.Results: Students’ perceptions of the care of children were generally very positive.  Some differences were found based on gender, phase of study and prior clinical exposure to pediatric care.  Pre and post responses were similar, regardless of preceptor specialty. Students with family physician preceptors identified the themes of prevention, health promotion and multidisciplinary care in their reflections. Conclusions: Students had already formed positive attitudes toward the medical care of children and intended to care for children in their future practice. Further research is needed into the effects of pre-clerkship experiences in the care of children on choice of medical specialty.

La doble campaña de producción en la agricultura, dicho de otra manera, es obtener dos cosechas en un año, la misma que es importante considerar en una agricultura eficiente y de buena rentabilidad, por lo mismo que es importante que el sector agroalimentario deberá adecuarse al ritmo de la competitividad necesaria a fin de convertirse en verdaderos centros de producción orientados al mercado con precios justos, mejorando los modelos de gestión, control de los procesos que faciliten la toma de decisiones e incorporen los avances tecnológicos; en muchos lugares se ha realizado proyectos de irrigación que facilitan el uso y manejo adecuado del agua de riego, sin embargo en muchas de ellas no consideran un aspecto muy importante como es el “desarrollo agrícola” que es la actividad decisiva para evaluar el impacto del proyecto y que a la larga será la que justifique la inversión realizada cuando los agricultores mejoren sus ingresos por mejor organización, aplicación de tecnologías, capacidad de negociación y mayor rentabilidad de sus productos, y consecuentemente mejoren su nivel y calidad de vida. En el presente documento se hace conocer las labores de investigación que se realizaron en el valle del Mantaro y otras zonas de la región Junín – Perú, con buenos resultados considerando cultivos tolerantes a las bajas temperaturas, precoces y de buena rentabilidad, uso eficiente del agua de riego y se propone además una cedula de cultivos base que se puede considerar para otras zonas interandinas.

Published: April 2020

As pesquisas antropológicas brasileiras podem tratar de forma frequentemente estanque e separada, por um lado, grupos camponeses e, por outro lado, grupos étnicos, quais sejam, ‘índios’, ‘quilombolas’, etc. Contextos e situações que indicam pluralidade identitária costumam ser simplificados em sua caracterização etnográfica e da dimensão multifacetada de relações e redes sociais. Assim, discuto aqui os processos de mobilização étnico-política e de demanda territorial, sem perder de vista os processos de ressignificação cultural e construção identitária que se engendram a partir de um campo semântico da etnicidade. Abordo, então, certas situações étnicas Tremembé (estado do Ceará) que desestabilizam, embaralham e colocam em risco representações antropológicas sobre o ‘camponês’, o ‘regional’ e o ‘indígena’.

Selection of Control Vector Switching Points for Circuit Optimization
Authors: Zemliak Alexander
Published: April 2020

The process of optimizing the circuit is formulated as a controlled dynamic system. A special control vector has been defined to redistribute the computational cost between circuit analysis and parametric optimization. This redistribution will help solve the task of optimizing the circuit for minimum CPU time. In this case, the task of optimizing the circuit with minimal CPU time can be formulated as the classical optimal control problem for minimizing some functional. The concept of the Lyapunov function of a controlled dynamic system is used to analyze the main characteristics of the design process. An analysis of the Lyapunov function and its time derivative makes it possible to predict the optimal structure of the control vector for constructing an optimal or quasi-optimal circuit design algorithm. The results are based on the previously discovered effect of accelerating the design process. In this case, the optimal structure of the control vector is determined, which minimizes processor time.

Observations of a Quasi-periodic Pulsation in the Coronal Loop and Microwave Flux during a Solar Preflare Phase
Authors: Li Dong , Li Ying , Lu Lei , Zhang Qingmin , Ning Zongjun , Anfinogentov Sergey
Published: April 2020

We report a quasi-periodic pulsation (QPP) event simultaneously detected from the spatial displacements of the coronal loop at both EUV images and microwave emission during the preflare phase of a C1.1 flare on 2016 March 23. Using the motion magnification technique, a low-amplitude transverse oscillation with the growing period is discovered in a diffuse coronal loop in Atmospheric Imaging Assembly (AIA) image sequences at wavelength of 171 Å, and the initial oscillation period is estimated to be ∼397 s with a slow growth rate of 0.045. At the same time, a QPP with growing periods from roughly 300 s to nearly 500 s is discovered in the microwave flux in the same active region. Based on the imaging observations measured at EUV wavelengths by the AIA and at microwave 17 GHz by Nobeyama Radioheliograph, the diffuse coronal loop and the microwave radiation source are found to be connected through a hot loop seen in AIA images at wavelength of 94 Å. The growing period of the QPP should be related to the modulation of LRC-circuit oscillating process in a current-carrying plasma loop. The existence of electric currents may imply the non-potentialities in the source region during the preflare phase.

Published: April 2020

The weed vegetation of the bean “Fagiolo Cannellino di Atina” (Phaseolus vulgaris L.) and the red pepper “Peperone di Pontecorvo” (Capsicum annuum L.) PDO (Protected Designation of Origin) crops was surveyed by means of 16 relevés, sampled in four farms of southern Latium during July 2019. The relevés were subjected to multivariate analysis, which revealed that the two crops are weeded by vegetation types referable to two different subassociations of Panico-Polygonetum persicariae (Spergulo-Erodion, Eragrostietalia, Digitario-Eragrostietea). Namely, communities colonizing bean fields, which are more mesophilous and richer in Eurasian taxa, are ascribable to the subassociation sorghetosum halepensis. Communities colonizing red pepper fields, which are more thermophilous and richer in Mediterranean taxa, are ascribable to the subassociation cyperetosum rotundi. Floristic, structural, and chorological features of the communities are discussed in relation to environmental factors and agricultural management.
Migrationally attractive municipalities in the regions of the Central Federal District (excluding regional centers)
Authors: Mokrensky Denis N.
Published: April 2020

In the absence of economic and demographic growth in most small and medium-sized towns outside the largest and major urban agglomerations of the Central Federal District, it is important to identify migrationally attractive municipalities, which, through the use of their competitive advantages, could become promising for the regions’ economic development in the near future. The purpose of this article is to identify migrationally attractive municipalities within the regions of the Central Federal District outside the regional centers. For this purpose, theoretical concepts of importance for explaining the migration attractiveness of territories have been studied, the dynamics of migration growth in the municipalities of the Central Federal District has been analyzed. The database of indicators for municipalities of the Central Federal District in Russia in 2011-2016 serves as the initial data for analysis (Kalabikhina et al. 2019). As a result, the migrationally attractive municipalities beyond the regional centers are allocated in 50% of the regions of the Central Federal District.

Presently, interval-valued neutrosophic set theory has become an important research topic. It is widely used in various pure as well as applied fields. This chapter will provide some essential scopes to study interval-valued neutrosophic subgroup. Here the notion of interval-valued triple T-norm has been introduced, and based on that, interval-valued neutrosophic subgroup has been defined. Furthermore, some homomorphic characteristics of this notion have been studied. Additionally, based on interval-valued triple T-norm, interval-valued neutrosophic normal subgroup has been introduced and some of its homomorphic characteristics have been analyzed.
Real-Time Neutrosophic Graphs for Communication Networks
Authors: Biswas Siddhartha Sankar
Published: April 2020

In this century the communication networks are expanding very fast in huge volumes in terms of their nodes and the connecting links. But for a given alive communication network, its complete core topology may not be always available to the concerned communication systems at a given real point of time. Thus, at any real-time instant the complete graph may not be available, but a subgraph of it to the system for executing its communication or transportation activities may be. In this chapter, the author introduces ‘real-time neutrosophic graphs' (RTN-graphs) in which all real-time information (being updated every q quantum of time) are incorporated so that the communication/transportation system can serve very efficiently with optimal results. Although the style and philosophy of Dijkstra's algorithm is followed, the approach is completely new in the sense that the neutrosophic shortest path problem (NSPP) is solved with the real-time information of the network where most of the data are neutrosophic numbers.
Solving Neutrosophic Linear Programming Problems With Two-Phase Approach
Authors: Badr Elsayed Metwalli , Abdul Salam Mustafa , Smarandache Florentin
Published: April 2020

The neutrosophic primal simplex algorithm starts from a neutrosophic basic feasible solution. If there is no such a solution, we cannot apply the neutrosophic primal simplex method for solving the neutrosophic linear programming problem. In this chapter, the authors propose a neutrosophic two-phase method involving neutrosophic artificial variables to obtain an initial neutrosophic basic feasible solution to a slightly modified set of constraints. Then the neutrosophic primal simplex method is used to eliminate the neutrosophic artificial variables and to solve the original problem.

Norms have a contribution in determining violence: how it starts, is unleashed, and its effect on the entirety of the society. They are important in moulding the behaviours of the people. However, they may be problematic and instigate violence. Realising an upsurge in violence emanating from some of the norms in Zimbabwean cultures, the study sought to understand all the various forms of norms, their functionalities, and how they influence violence before seeking to craft means of challenging them. The study is guided by the social norms approach. The study found out that social and cultural norms have over a period grown to define most societies' ways of life. However, there are elements that always try to create conflicts. To attend to the disruptive elements, there are interventions that may be applied to challenge some of these norms, usually combined with other methods, legislation and policies, education, adoption of contemporary world standards, communication, and inclusive lobbying and advocacy, among others.

The Berantai Field is a marginal sand-prone formation located offshore in the Malaysian Peninsula, and its development was chosen for Malaysia's first and second Risk Service Contracts (RSCs) to provide gas production within two years of the Field Development Project (FDP)'s execution. This field was initially considered as marginal with only an estimated 44 mmstb of oil and 440 mmscf of gas.

A key performance requirement was to complete and produce the gas wells, sand free at the targeted production rate of 150 mmscfd. However, during development of the field, up to twenty multilayered, unconsolidated sand formations that had not been forecasted in the FDP were discovered, increasing the challenges for the completion strategy.

The dual-string single-trip multi zone (STMZ) system was selected for the completions, as this technology had been proven to provide cost-effective, single-trip gravel-pack applications that could reduce overall cost, since the gravel packing for multiple zones could be performed in a single trip. Although completing long intervals has unique challenges for fixed- interval spacing, and the initial campaign presented other challenges, all seven wells were successfully delivered. A total of thirty one zones were treated. One of the wells not only had six gravel-packed zones completed in one trip, but also had the world's longest concentric wash pipe used in any dual string STMZ completion.

This paper will show how proper completion planning and dual string STMZ technology enabled the operator to deliver the committed gas production, saved ~150K USD per gravel-packed zone, and reduced approximately 2.2 days in average rig time per well. The challenges addressed during this campaign, the methodology followed in the completion design, detailed completion and pumping strategy success factors, and the production results obtained from this marginal field development will be presented.

SLAM-associated protein (SAP) is an adaptor molecule that facilitates critical effector functions in immune cells, and its deficiency causes X-linked lymphoproliferative disease type 1 in which effector responses directed against EBV are severely compromised. The primary objective of this study was to phenotypically and functionally characterize a rare, CD8 T cell–restricted bimodal SAP expression pattern observed in healthy, human donors with the widely used 1C9-SAP mAb clone. We initially observed this pattern during the clinical validation of our flow cytometry–based assay to diagnose X-linked lymphoproliferative disease type 1 in our laboratory. For this validation study, we used multiparameter flow cytometry to identify cytosolic SAP expression in lymphocyte subsets, and CD8 T cells from the donors displaying the rare SAP expression pattern mentioned above were separately further evaluated by intracellular cytokine and CD107a staining to examine polyfunctionality following PMA/ionomycin and HLA class I allele–restricted EBV peptide epitope–induced T cell activation. Our data revealed that SAP 1C9-hi CD8 T cells clearly displayed higher polyfunctional responses versus SAP 1C9-lo CD8 T cells following PMA/ionomycin stimulation. Furthermore, polyfunctional EBV-specific CD8 T cell responses segregated with the SAP 1C9-hi CD8 T cells and not the SAP 1C9-lo CD8 T cells. Additionally, and rather intriguingly, short- and long-term T cell stimulation selectively diminished the signal for the 1C9-hi subset. Overall, our data suggest that although rare, this unique SAP expression pattern merits further evaluation as it has the potential to provide some insight into fundamental processes as they might relate to host–pathogen dynamics.
Variabilité du manteau neigeux des Alpes Européennes entre 1950 et 2016 dans un contexte de changement climatique : revue bibliographique
Authors: Klein Geoffrey
Published: April 2020

Les régions de montagne, particulièrement vulnérables aux fluctuations du climat, ont subi d’importantes modifications environnementales au cours du XXe siècle. L’augmentation observée des températures de l’air depuis les années 1950 a notamment engendré un net recul des glaciers, mais aussi du manteau neigeux à toutes les altitudes. Cette réduction de l’enneigement en montagne est un facteur préoccupant dans de multiples domaines, qu’il s’agisse des écosystèmes, des cycles hydrologiques, ou encore du tourisme alpestre. De nombreux travaux de recherche à travers le monde témoignent du réchauffement de l’air et de la réduction observée du manteau neigeux dans les massifs montagneux depuis les années 1950, essentiellement à basse et moyenne altitude, mais peu de synthèses de ces différents changements ont été faites jusque-là. Cette revue bibliographique a pour but de faire l’état des lieux des principaux changements observés du manteau neigeux depuis le XXe siècle dans les Alpes européennes et leur mise en relation avec les changements climatiques relevés sur la même période. Un aperçu des différentes conséquences déjà observées sur les cycles hydrologiques, le tourisme hivernal et les écosystèmes est également présenté, ainsi que les projections futures d’évolution des paramètres du manteau neigeux d’ici la fin du XXIe siècle. Cette revue bibliographique fournit une source d’information utile pour les futures recherches se focalisant sur l’étude de la saisonnalité du manteau neigeux en région de montagne et ses implications directes, en particulier dans les zones alpines et subalpines.
Modeling Crack Patterns by Modified STIT Tessellations
Authors: León Roberto , Nagel Werner , Ohser Joachim , Arscott Steve
Published: April 2020

Random planar tessellations are presented which are generated by subsequent division of their polygonal cells. The purpose is to develop parametric models for crack patterns appearing at length scales which can change by orders of magnitude in areas such as nanotechnology, materials science, soft matter, and geology. Using the STIT tessellation as a reference model and comparing with phenomena in real crack patterns, three modifications of STIT are suggested. For all these models a simulation tool, which also yields several statistics for the tessellation cells, is provided on the web. The software is freely available via a link given in the bibliography of this article. The present paper contains results of a simulation study indicating some essential features of the models. Finally, an example of a real fracture pattern is considered which is obtained using the deposition of a thin metallic film onto an elastomer material – the results of this are compared to the predictions of the model.
Intelligence Sources in the Process of Collection of Information by the U.S. Intelligence Community
Authors: Kamiński Mariusz Antoni
Published: April 2020

Every day, U.S. intelligence agencies gather huge amounts of information from a variety of sources. Collection of information is an essential part of the process described as Intelligence Cycle. The purpose of this article is to identify the essence and nature of intelligence sources and to analyze their practical use by the agencies and departments that make up the U.S. Intelligence Community. The author characterizes the main types of intelligence sources – Human Intelligence (HUMINT), Geospatial Intelligence (GEOINT), Signals Intelligence (SIGINT), Measurement and Signature Intelligence (MASINT), and Open Source Intelligence (OSINT) – and indicates which U.S. intelligence agencies are responsible for their use. Moreover, the author presents the problems with the use of intelligence sources that occur in the work of the U.S. Intelligence Community. Research findings indicate that the best results of intelligence work can be achieved with the use of “all-source intelligence” (also referred to as fusion intelligence), which involves using as many sources as possible to prepare a final intelligence product.

Published: April 2020

The present research aims to advance green energy consumption by integration of energy conversion schemes into buildings, as an inherent part of architectural construction. Realization of such tasks implies variation and adjustment of external shapes of buildings. Particular solutions depend on the chosen types of renewable energy sources, geographic location, and environmental conditions. The novelty of suggested solutions based on the principle of preliminary crowding of solar radiation, but against known analogs concentration of light by mirrors here used not for achieving of high amplitudes, but for diurnal equalization of an energy conversion process. Autodesk software products have been used for adjustment of conceptual schemes, including the models of buildings shaped as right circular, or elliptic, cylindrical reflectors. The basic evaluation carried out for the North Temperate Zone. Obtained results confirm that integration of local energy converters and appropriate modification of external shapes of buildings is more flexible and efficient than the application of centralized solar plants, because of their inexpensiveness and harmonization of beauty and energy efficiency. Application of static self-regulation of illuminance provides a high level of reliability and simplicity in exploitation. Suggested principle provides stepwise promotion of sustainability because it implies not only a passive economy of energy dissipation but also the equipment of architectural objects with inherent modules for active generation of renewable energy. Further development of such an energy sourcing schemes related also with the advancement of general safety (lowering of hazardous voltage) by the transition from common Electrical grid to adaptive local systems.
