Generalized Contractive Mappings and Related Results in b-Metric Like Spaces with an Application

In this article, a general contractive mapping is presented and some fixed point results in complete b-metric-like spaces are studied. The results obtained here extend and improve some related results in the literature. Also, new common fixed point results for a graphic contraction mappings are proved. Some comparative examples are given to support the obtained results. Moreover, an analytical solution of an integral equation has been presented as an application.

Solution of Nonlinear Integral Equation via Fixed Point of Cyclic $$\alpha _{L}^{ \psi }$$αLψ-Rational Contraction Mappings in Metric-Like Spaces

In this paper, we introduce the notions of $$\alpha _{L}^{\psi }$$-rational contractive and cyclic $$\alpha _{L}^{\psi }$$- rational contractive mappings and establish the existence and uniqueness of fixed points for such mappings in complete metric-like spaces (dislocated metric spaces). The results presented here substantially generalize and extend several comparable results in the existing literature. As an application, we prove new fixed point results for $$\psi L$$-graphic and cyclic $$\psi L$$-graphic rational contractive mappings. Moreover, some examples and an application to integral equation are presented here to illustrate the usability of the obtained results.

OrganellarGenomeDRAW (OGDRAW) version 1.3.1: expanded toolkit for the graphical visualization of organellar genomes.

Organellar (plastid and mitochondrial) genomes play an important role in resolving phylogenetic relationships, and next-generation sequencing technologies have led to a burst in their availability. The ongoing massive sequencing efforts require software tools for routine assembly and annotation of organellar genomes as well as their display as physical maps. OrganellarGenomeDRAW (OGDRAW) has become the standard tool to draw graphical maps of plastid and mitochondrial genomes. Here, we present a new version of OGDRAW equipped with a new front end. Besides several new features, OGDRAW now has access to a local copy of the organelle genome database of the NCBI RefSeq project. Together with batch processing of (multi-)GenBank files, this enables the user to easily visualize large sets of organellar genomes spanning entire taxonomic clades. The new OGDRAW server can be accessed at https://chlorobox.mpimp-golm.mpg.de/OGDraw.html.

PhyloPi: An affordable, purpose built phylogenetic pipeline for the HIV drug resistance testing facility.

IntroductionPhylogenetic analysis plays a crucial role in quality control in the HIV drug resistance testing laboratory. If previous patient sequence data is available sample swaps can be detected and investigated. As Antiretroviral treatment coverage is increasing in many developing countries, so is the need for HIV drug resistance testing. In countries with multiple languages, transcription errors are easily made with patient identifiers. Here a self-contained blastn integrated phylogenetic pipeline can be especially useful. Even though our pipeline can run on any unix based system, a Raspberry Pi 3 is used here as a very affordable and integrated solution.Performance benchmarksThe computational capability of this single board computer is demonstrated as well as the utility thereof in the HIV drug resistance laboratory. Benchmarking analysis against a large public database shows excellent time performance with minimal user intervention. This pipeline also contains utilities to find previous sequences as well as phylogenetic analysis and a graphical sequence mapping utility against the pol area of the HIV HXB2 reference genome. Sequence data from the Los Alamos HIV database was analyzed for inter- and intra-patient diversity and logistic regression was conducted on the calculated genetic distances. These findings show that allowable clustering and genetic distance between viral sequences from different patients is very dependent on subtype as well as the area of the viral genome being analyzed.AvailabilityThe Raspberry Pi image for PhyloPi, source code of the pipeline, sequence data, bash-, python- and R-scripts for the logistic regression, benchmarking as well as helper scripts are available at http://scholar.ufs.ac.za:8080/xmlui/handle/11660/7638 and https://github.com/ArmandBester/phylopi. The PhyloPi image and the source code are published under the GPLv3 license. A demo version of the PhyloPi pipeline is available at http://phylopi.hpc.ufs.ac.za/.

A Modified FOPID Versus H∞ and µ Synthesis Controllers: Robustness Study

The H∞, µ synthesis and fractional order (FPM) controllers are types of robust designs that use the linearized model of the system and provide a linear controller. The µ synthesis approach directly considers the uncertainty, but H∞ and FOPID run for the worst uncertainty scenario. mFPM is the modified version of FOPID design where 1) it takes into account the given uncertainty by a graphical Phase Margin Distribution Map (PMDP), and 2) reduces the controller design calculations by working on the samples of the system frequency response instead of its analytical equation. The design strategy can perfectly force the desired flatness in the phase margin band and maintain the system performance robustness. For evaluation, the algorithms are applied to a second-order uncertain system and a perturbed UAV roll control. In both cases, the lowest output response variance and the best performance robustness is gained from the mFPM design. This is verified through numerous simulations.

Quantification of particulate matter, tracking the origin and relationship between elements for the environmental monitoring of the Antarctic region

The present work reports on the analysis of atmospheric aerosols in the Antarctic region, Deception Island, collected during austral summer 2016–2017 by field measurements carried from Gabriel de Castilla Spanish Research Station. A low-volume sampler was used to capture the aerosols depositing them onto the air filters. A chemical analysis of the samples using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) and Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES) provided the total carbon (TC), organic carbon (OC), elemental Carbon (EC) and elements such as Al, Ca, Fe, K, Mg, Na, P, S, Cu, Pb, Sr, Ti, Zn and Cr. The average mass concentration of particulate matter (PM10) originated by natural and anthropogenic activities was calculated as 10 ± 4 μg/m3, although values such as 28.2 μg/m3 were also obtained which is very high even when compared to other places in the coast of the Antarctic region. In addition, high enrichment factors have been found for elements such as Pb, Cr, Cu and Zn showing a remote anthropogenic contribution to particulate matter in this region. Correlations were found between Na, Mg, Ca, Al, Ti and S, where Na/Mg displayed the influence of marine environments, S correspond to volcanic activities, Ca to penguin colonies and influence of sea whereas Al/Ti indicated the crustal origin. Polar contour graphical maps were obtained from meteorological data using chemometrics methods, which allowed reproducing wind maps revealing the distribution of the aerosols and possible emission sources of different elements in the area. Given that this island has not been previously studied for atmospheric contamination, this work provides an interesting insight about the site-specific characteristics of particulate matter.

Technology-based business incubators

PurposeTechnology-based incubators depend on high-level knowledge to constantly meet the demands of the market. Incubators offer a variety of specialized services to help startups increase the chances of crossing the valley of death. These services include infrastructure, access to a professional network of mentors and an intensive support of a consultant team to help with managerial and legal challenges. Therefore, it is critical to incubators to develop both highly skilled teams of consultants and social environment that facilitates communication. The purpose of this paper is to understand how innovation-oriented social networks created within technology-based incubators are shaped.Design/methodology/approachData were collected in five incubators participating connected to federal universities from the state of Minas Gerais. The network attributes collected in the survey were placed in a matrix form. The mapping and measurement of the relationships between individuals were developed using the Ucinet software. Ucinet enables the analysis of attributes (attitudes, behaviors and characteristics) characterized as relational (contacts, ties and relationships). The software also includes the Netdraw network visualization tool, which enables the creation of matrices and graphical network maps. The measurements of centrality, closeness and intermediation were analyzed to assess the intra-organizational social network.FindingsThe results indicate that although the flow of communication does not follow the formal hierarchy, the interaction between team members to spontaneously exchange ideas, information and experiences is rare. The workers are so concerned about their timely tasks, that they have few opportunities to exchange information and knowledge. The coordination is carried out by university professors, who also perform other tasks (e.g. teaching, research and administration activities) besides those related to the incubators. The results also suggest that in the technology-based incubators studied, besides dealing in an innovative environment, the distribution of tasks and responsibilities are still rigid and traditional.Originality/valueBy analyzing the degree of the relationship between team members, the proximity and the level of intermediation of co-workers, it is possible to see how the incubators workers interact, thereby identifying the flow of information. This study offers implications for theory and practice. To the theory, this study adds to the discussion of intra-organizational social network of technology-based companies in the Brazilian context. To practitioners, this research sheds light on the importance of the social network built within the organization to promote effective communication and knowledge sharing.

Cartographic presentation – from simple to complex map

Abstract Nowadays a lot of people are trying to make maps, and especially digital maps. A wide range of computer tools and high graphic capabilities have together made maps increasingly popular and seemingly easy to prepare for any person who can use a computer. It seems necessary to verify the bases of the cartographic presentation methods. There is a need for a new, formalized view of the method as a sequence of steps from data collection, to correct presentation, to map. Two terms related to cartographic presentation should be distinguished in this article: “methods” and “forms.” A method is understood as the process by which data is transformed into a presentation. A form is understood as the end result of this process, i.e. the resulting graphical image or map. In the article five types of cartographic presentation are indicated. In the successive types, one can observe an increasing degree of complexity of cartographic presentation.

Multidimensional Proton Nuclear Magnetic Resonance Relaxation Morphological and Chemical Spectrum Graphics for Monitoring and Characterization of Polyunsaturated Fatty‐Acid Oxidation

AbstractPolyunsaturated fatty acids (PUFA) are components of many commercial products such as edible oils, foods, cosmetics, medication, and in biological systems such as phospholipids of cellular membranes. Although PUFA aggregates are important functional components, they are also related to system degradation, because PUFA are susceptible to oxidation via their multiple double bonds and allylic carbons. Current technologies are not effective in characterizing the morphological and chemical structural domains of saturated, monounsaturated fatty acids (MUFA) and PUFA materials, or how the morphological structures of fatty acids, at the mesomolecular, nanomolecular, and molecular levels, affect their oxidation mechanisms. In this article, the 1H low‐field (LF) NMR energy relaxation time technology is proposed as a tool to analyze PUFA oils undergoing thermal oxidation. This technology generates two‐dimensional (2D) chemical and morphological spectra using a primal‐dual interior method for the convex objectives (PDCO) optimization solver for computational processing of the energy relaxation time signals T1 (spin–lattice) and T2 (spin–spin). The 2D graphical maps of T1 vs. T2 generated for butter, rapeseed oil, soybean oil, and linseed oil show that the different degrees of unsaturation of fatty‐acid oils affect their chemical and morphological domains, which influences their oxidative propensity. The technology of the 1H LF‐NMR energy relaxation time proved to be an effective tool to characterize and monitor PUFA oxidation.

Genome Survey Sequencing of Acer truncatum Bunge to Identify Genomic Information, Simple Sequence Repeat (SSR) Markers and Complete Chloroplast Genome

The Acer truncatum Bunge is a particular forest tree species found in the north of China. Due to the recent discovery that its seeds contain a considerable amount of nervonic acid, this species has received more and more attention. However, there have been no reports of the genome in this species. In this study, we report on the Acer truncatum genome sequence produced by genome survey sequencing. In total, we obtained 61.90 Gbp of high-quality data, representing approximately 116x coverage of the Acer truncatum genome. The genomic characteristics of Acer truncatum include a genome size of 529.88 Mbp, a heterozygosis rate of 1.06% and a repeat rate of 48.8%. A total of 392,961 high-quality genomic SSR markers were developed and a graphical map of the annotated circular chloroplast genome was generated. Thus far, this is the first report of de novo whole genome sequencing and assembly of Acer truncatum. We believe that this genome sequence dataset may provide a new resource for future genomic analysis and molecular breeding studies of Acer truncatum.

Geographical mapping of advanced practice registered nurses in Louisiana: Leveraging the power of data display.

Identifying the locations of advanced practice registered nurses (APRNs) in the state is challenging without data readily available, which can adversely affect stakeholder initiatives. The purpose of this project was to develop an online interactive map reflecting distribution of APRNs licensed by the Louisiana State Board of Nursing (LSBN), heightening APRN visibility and improving usability of data for policy, education, practice, and research initiatives. A descriptive design with development of a graphical interactive map showing all Louisiana parishes with integrated distribution summaries of APRNs was made. Work proceeded from paper to higher fidelity simulations to the final interactive web page. Compatibility with LSBN's web page and annual data upload were ensured. The project was done in collaboration with LSBN, an academic institution, and a privately hired web designer. The principals of Louisiana State Board of Nursing approved the final product. The product meets and exceeds the expectations for mapping. Evaluation of use and usability will be done at the discretion of LSBN. The outcome of this project will serve to heighten visibility of the distribution of APRNs in the state of Louisiana, enhancing opportunities for APRNs and for patients. Furthermore, those interested in leveraging the information in policy, education, or research initiatives will be served.

ПРИМЕНЕНИЕ ИНСТРУМЕНТОВ МАРКЕТИНГА В ДЕЯТЕЛЬНОСТИ КОНСАЛТИНГОВОЙ КОМПАНИИ

The development of the consulting market and the growth of competition in it require modern approaches to the presentation of marketing strategies for consulting services. The article presents the types of marketing, recommended schemes of organization of the marketing system, and also proposed methods for building customer loyalty of a consulting firm (consultant). The purpose of the study is to justify the use of marketing tools in the activities of consulting companies in the implementation of marketing policies aimed at building such communications with customers that will demonstrate the high intellectual potential and professionalism of consultants, their independence and objectivity. To achieve this goal, the following methods were used: dialectical (research of processes and phenomena in interrelation and development), structural-functional, situational, comparative, graphical and tabular mapping of economic and factual data. The study showed that consultants, when promoting their services, should be presented in all areas and areas of advertising, and on the Internet (website, forum, newsletter), and offline (in newspapers, magazines, radio, TV, outdoor advertising). The use of marketing tools aimed at the promotion of consulting services, provides an opportunity to get real customers, contribute to the formation of loyalty to consulting in business, form the flow of information about the need to use consulting services to develop and strengthen business. In this regard, being a highly professional consultant is no longer enough; you must also be able to sell your services using the full range of marketing technologies and tools.

Narrative mapping as cognitive activity and as active participation in storyworlds

AbstractEver the devil’s advocate, Richard Walsh argues in a 2017 article that drawing maps based on narrative fiction is a meaningless activity, because (1) narrative cognition is temporal and not spatial; (2) narrative fiction does not project worlds in any experiential sense of the term (i. e. worlds as immersive environments) but only “worlds” as textual constructs, as products ofécriture; and (3) reading should lead to meaningful interpretations, and inferences should be limited by a principle of relevance. His example of futile map-making is the floor plan which is included in the English editions of Alain Robbe-Grillet’sLa Jalousiebut is absent from the original French edition. In this article, I argue that narrative cognition is not a specialized ability distinct from the forms of cognition that we use in practical life, but rather, the product of these abilities; and I defend the validity of narrative mapping as way to engage the imagination with – yes – a storyworld. This is not to say that narrative understandingrequiresthe drawing or mental contemplation of a comprehensive representation of the storyworld; usually the formation of partial mental maps is sufficient to follow the plot. But for some readers (among them Nabokov) drawing graphic maps is a way to engage the imagination with the storyworld and to enhance comprehension. This map-making activity can go far beyond making sense of the text and become an autonomous activity comparable to writing fan fiction. To support this view, I invoke the numerous maps found on the Internet for narratives ranging from Proust’sA la recherche du temps perduto Tolkien’sLord of the Rings. While the strictly “textualist” aesthetics of orthodox literary theory would regard these maps as frivolous, a world-oriented approach regards the urge to map and diagram as a legitimate form of active participation in narrative, because, while you can imagine too little to appreciate these texts, you cannot imagine too much.

Effect of Size, Shape and Map Background in Cartographic Visualization: Experimental Study on Czech and Chinese Populations

This paper deals with the issue of the perceptual aspects of selected graphic variables (specifically shape and size) and map background in cartographic visualization. The continued experimental study is based on previous findings and the presupposed cross-cultural universality of shape and size as a graphic variable. The results bring a new perspective on the usage of shape, size and presence/absence of background as graphic variables, as well as a comparison to previous studies. The results suggest that all examined variables influence the speed of processing. Respondents (Czech and Chinese, N = 69) identified target stimuli faster without a map background, with larger stimuli, and with triangular and circular shapes. Czech respondents were universally faster than Chinese respondents. The implications of our research were discussed, and further directions were outlined.

Finding a place for genealogy and family history in the digital humanities

PurposeDespite its growing popularity, there is a noticeable absence of references to the inclusion of genealogy and family history studies within the field of digital humanities. New forms of inclusiveness, particularly in production-coding and cultural analysis, closely align genealogy and family history with the core tenants practiced among humanities computing and digital humanities. This paper aims to prove that genealogy as family history should be formally recognized within this cohort, as it can serve as a valuable and innovative partner for advocacy and technological advancement of the field.Design/methodology/approachBy examining the literature, genealogy will be defined according to its use in the digital humanities, as well as its use in family history studies. The core tenants of humanities computing and digital humanities will be identified and compared against the research methodology and technological tools used in genealogy and family history research. The comparison will determine how closely the fields align, and if genealogy defined as family history should be used, and included within the field of digital humanities.FindingsThe progression of genealogy and family history from production to cultural analysis corresponds with the transition of production and coding (influenced by humanities computing) to the inclusion of experimental cultural research adopted by the digital humanities. Genealogy’s use of technological tools, such as databases, text encoding, data-text mining, graphic information systems and DNA mapping, demonstrates the use of coding and production. Cultural analysis through demographic study, crowdsourcing and establishing cultural connections illustrates new methods of scholarship, and connects coding and cultural criticism, serving as a bridge between digital humanities and the humanities at large. As genealogy continues to create new partnerships of a collaborative nature, it can, and will, continue to contribute to new areas of study within the field. As these practices continue to converge with the digital humanities, genealogy should be recognized as a partner and member in the digital humanities cohort.Originality/valueDespite its growing popularity, there is a noticeable absence of references to the inclusion of genealogy and family history studies within the field of the digital humanities. The term genealogy resonates differently within the digital humanities, primarily articulating the history of the field over the study and research of family lineage. This study seeks to demonstrate how genealogy and family history can fit within the digital humanities, providing a new perspective that has not yet been articulated in the scholarly literature.

Malaria Vulnerability Map Mobile System Development Using GIS-Based Decision-Making Technique

This paper aimed at improving the lack of GIS information use and compatibility of multiplatform which represented limits that existing malaria risk analysis tools had. For this, the author developed mobile web-based malaria vulnerability map system using GIS information. This system consists of system database construction, malaria risk calculation function, visual expression function, and website and mobile application. This system was developed based on Incheon region only. Database includes information on air temperature and amount of precipitation as well. With regard to malaria risk calculation, guideline provided by Korea Centers for Disease Control and Prevention was followed first and then decision-making technique was used. Calculating criteria value for risk index made it possible to estimate more precise risk. With regard to visual expression function, database constructed earlier and risk information were linked to print out graphic map and graphs so that more intuitive and visible expression can be provided based on animation technique. This system allows a user to check information in real time and can be used anywhere anyplace. Mobile push function is to enhance user’s convenience. Such web map is useful to general users as well as experts.

Design and Implementation of an Optimal Travel Route Recommender System on Big Data for Tourists in Jeju

A recommender system is currently applied in many different domains, seeking to provide users with recommendation services according to their personalized preferences to relieve rising online information congestion. As the number of mobile phone users is large and growing, mobile tourist guides have attracted considerable research interest in recent years. In this paper, we propose an optimal travel route recommender system by analyzing the data history of previous users. The open dataset used covers the travel data from thousands of mobile tourists who visited Jeju in a full year. Our approach is not only personalized to users’ preferences but also able to recommend a travel route rather than individual POIs (Points of Interest). An association rule mining-based approach, which takes into account contextual information (date, season and places already visited by previous users), is used to produce travel routes from the large dataset. Furthermore, to ensure the reasonability of the recommendation, a genetic algorithm optimization approach is proposed to find the optimal route among them. Finally, a mobile tourist case study is implemented in order to verify the feasibility and applicability of the proposed system. This application embeds a graphic map for plotting the travel route and provides detailed information of each travel spot as well. The results of this work indicate that the proposed system has great potential for travel planning preparation for mobile users.

Understanding Parents' Perceptions of School-Based BMI Screening and BMI Report Cards Using Perceptual Mapping: Implications for School Nurses.

Half of U.S. states measure students' body mass index (BMI), with many communicating that information to parents through a "BMI report card" or notification letter. School nurses are usually responsible for implementing these programs and communicating results to parents. The purpose of this study was to understand parents' perceptions of BMI screening programs to help inform school nurses about messages that are most helpful to use in report cards to motivate parents to follow-up with a health-care provider or to make behavioral changes for their child. Using a cluster analysis and perceptual mapping methods, a commercial marketing technique that creates three-dimensional graphic maps, we identified four unique clusters of parents based on their core attitudes and beliefs related to BMI screenings and report cards. Based on vector modeling techniques, key message strategies were developed that can be used by school nurses to enhance parent response to a BMI report card.

A Scientometric Study of Neurocomputing Publications (1992–2018): An Aerial Overview of Intrinsic Structure

The international journal of neurocomputing (NC) is considered to be one of the most sought out journals in the computer science research fraternity. In this paper, an extensive bibliometric overview of this journal is performed. The bibliometric data is extracted from the Web of Science (WoS) repository. The main objective of this study is to reveal internal structures and hidden inferences, such as highly productive and influential authors, most contributing countries, top institutions, collaborating authors, and so on. The CiteSpace and VOS viewer is used to visualize the graphical mapping of the bibliometric data. Further, the document co-citations network, cluster detection and references with strong citation burst is analyzed to reveal the intellectual base of NC publications.
