Regulatory Dichotomy of Sucralfate, Its history and the new Bioadhesive polymerized Sucralfate barrier therapy for Oral health, Oncology support and Gastrointestinal disorders
Authors: McCullough Ricky Wayne
Published: October 2019

Sucralfate is a biologically inert non-systemically acting compound. It requires polymerization for conversion into its biological active form, polymerized Sucralfate. Should this conversion occur in the body, using processes of the body to effect conversion subsequent to administering a dose, then the administered Sucralfate is a drug, as it enlists bodily functions to enact a chemical change. This form of Sucralfate should be regulated as drug. On the other hand, Sucralfate is manufactured as a polymerized product, requiring no bodily functions to enable its therapeutic effect, then this form of Sucralfate act as a medical device and should be regulated as such. This dichotomy of Sucralfate was first recognized by the US FDA in 2005 that subsequently cleared several polymerized Sucralfate barrier therapies as medical devices.This review covers the history of the regulatory dichotomy or duality of Sucralfate, the biological basis for Sucralfate clinical effects and the regulatory position of several barrier therapies.

Personagens femininas na animação contemporânea: um olhar a partir da teoria e da crítica feminista
Authors: Penkala Ana Paula
Published: October 2019

O presente texto é parte de uma pesquisa mais ampla através da qual se busca um olhar sobre os produtos audiovisuais a partir da teoria, da crítica e, especificamente dos conceitos feministas. O artigo traz como recorte a articulação dos conceitos de público e privado e relacionados à mitologia do herói com as narrativas de Os Incríveis 2 e de Carros 3, mobilizando, para tanto, as noções sobre a construção política do gênero, a atualização das normas nas narrativas, a maneira como o patriarcado é sustentado por um sistemático reforço de “verdades” e “universalidades”. Sustentam essa abordagem as perspectivas de Susan Okin (2008), Flávia Biroli (2014) e Carole Pateman (1993) sobre os contratos sociais e sexuais; de Heleieth Saffioti (2015) sobre o próprio patriarcado; Simone de Beauvoir (1967) sobre a socialização feminina e a construção política da mulher; sobre o audiovisual como tecnologia de gênero em Teresa de Lauretis (1987) e os trabalhos de Joseph Campbel (1997), Carl Jung (2013) e Roland Barthes (1989) sobre os mitos enquanto discursos.

A LESSON DESIGN OF ALGEBRAIC THINKING IN ELEMENTARY SCHOOL AS AN EFFORTS TO DEVELOP MATHEMATICAL LITERATION IN INDUSTRIAL ERA 4.0
Authors: Pratiwi Vira , Farokhah Laely , Abidin Zaenal
Published: October 2019

Algebraic thinking is one of the abilities needed in the industrial era 4.0. The efforts to instill algebraic thinking need to be done since elementary school students. Before students learn about algebra, they must have a lot of experience in making representations, abstractions, and generalizations. The ability to represent data using tables and diagrams is one indicator of algebraic thinking. This research was conducted discovery of learning obstacles thinking algebra by representing data using tables and diagrams in elementary school. Learning obstacles include ontogenically obstacles, epistemological obstacles, and didactical obstacles. Therefore, it is necessary to develop didactic designs to overcome these learning obstacles. The research method used was Didactical Design Research (DDR). This research was conducted by analyzing learning obstacles that were found to be used as the development of learning trajectories. The analysis process produces alternative didactic situations that can overcome obstacles in thinking algebra. Given that algebraic thinking in the curriculum in elementary schools is still implied, it is necessary to develop a comprehensive lesson design to facilitate students in developing algebraic thinking. The ability to think algebra is the high order thinking skills, they need to face various challenges today.

Authors: Hussain Eman Ali , Al-Hawasy Jamil A. , Ali Lamyaa Hussein
Published: October 2019

This paper concerned with the solution of the nanoscale structures consisting of the   with an effective mass envelope function theory, the electronic states of the  quantum ring are studied.  In calculations, the effects due to the different effective masses of electrons in and out the rings are included. The energy levels of the electron are calculated in the different shapes of rings, i.e., that the inner radius of rings sensitively change the electronic states. The energy levels of the electron are not sensitively dependent on the outer radius for large rings. The structures of  quantum rings are studied by the one electronic band Hamiltonian effective mass approximation, the energy- and position-dependent on electron effective mass approximation, and the spin-dependent on the Ben Daniel-Duke boundary conditions. In the description of the Hamiltonian matrix elements, the Finite elements method with different base linear triangular element is adopted. The non-linear energy confinement problem is solved approximately by using the Finite elements method with  linear triangular element, to calculate the energy of the electron states for the   quantum ring.
The Bimodal Color Distribution of Galaxies at Redshift of z=0-0.15 from the Sloan Digital Sky Survey (SDSS)
Authors: Mahdi Hareth Saad
Published: October 2019

This work aims to use the color distribution of galaxies to differentiate between blue and red galaxies. The photometric data of 300000 galaxies at redshift of z = 0 – 0.15 were collected from the Sloan Digital Sky Survey (SDSS). Three redshift ranges were considered for the purpose of this work: 100000 galaxies at z = 0-0.05, 100000 galaxies at z = 0.05-0.1 and 100000 galaxies at z = 0.1-0.15. The color distributions for all redshift ranges were determined. The results have clearly shown that the color distributions for all redshift ranges are bimodal. One of the two peaks corresponds to the blue galaxies (young and star-forming galaxies), whereas the other peak corresponds to the red galaxies (old and non-star-forming galaxies). Therefore, the color distribution of galaxies can be considered as an efficient tool to distinguish between blue and red galaxies.

Role of Education in Financial Inclusion of Poor and Unbanked Women in India
Authors: Sabic-El-Rayess Amra
Published: October 2019

In recent times, the global financial system has embraced more people from more regions of the world, but we are yet to fully understand who remains excluded and why. Globally, 2 billion adults are still unbanked (World Bank, 2015). Of those, many are poor women. Even when they gain financial access, women tend to refrain from actively using their bank accounts. India represents a potent example of this global challenge. Our study offers a quantitative analysis of the Financial Insights Inclusion and Findex datasets and finds that even when they are given the opportunity and potential benefits of financial access - many of India’s poor women opt out of actively engaging with the formal banking institutions. In examining reasons behind their account dormancy, we find that education is a significant determinant shaping decisions of India’s poor women.

Politeness of expression and character education are both crucial aspects, in the current era of disruption, especially concerning sociopragmatic political purposes. The realization of politeness acts of language in the context of communication and global communication has now penetrated without limits on social distance, time, and goals. The problem is the act of language in electronic media, especially Instagram, giving space to the user to be more open in expressing his goals and objectives, including to the president in relation to specific goals and politics. This study aims to identify the forms of positive politeness acts of followers' comments on President Jokowi's official Instagram account and describe the intent of politico pragmatic power of positive politeness of followers of Jokowi's Instagram accounts. The data source of this study was the speech of followers on the official Instagram account of Indonesian President Jokowi #MenujuIndonesiaMaju managed by the President's Digital Communication Team for the period October-November 2018. The study data were in the form of comments from Jokowi's Instagram account followers who had positive politico pragmatic politeness. The data collection technique was carried out using documentation, note-taking techniques, and continued with heuristic listening techniques. Data analysis was performed with an intralingual equivalent technique which was strengthened by an extra lingual equivalent and sharpened with Levinson's politeness analysis technique based on the principle of harmony in Javanese culture. The results of the study showed that the form of positive politeness acts that were most used by followers was by giving attention to the speech partners. Political propaganda power of dominant followers’ comments was in the form of the power to ask and support rather than the power of praise, the power of influence, the power of motivation, and the power of suggestion. It shows that Instagram account followers have an optimistic attitude towards Jokowi's leadership. Jokowi's managerial, and leadership performance has a positive face among followers. This power of praise, motivation, and advice is an essential component in the formation of children's character education in the current era of disruption of education.
Entre omissão e preconceito racial: discurso-acontecimento
Authors: Lobo Dalva de Souza , Villarta-Neder Marco Antonio , Ferreira Helena Maria
Published: October 2019

O presente artigo tem por objetivo problematizar a proposição/implementação de currículos que abordem as relações étnico-raciais em cursos de professores de língua portuguesa. Nessa direção, a partir de pressupostos epistemológicos do campo bakhtiniano, buscamos defender que a concepção tradicional como um conjunto de disciplinas, conteúdos e atividades não consegue contemplar dimensões que abarquem as interações estabelecidas para que a aprendizagem em uma perspectiva crítica se efetive. Assim, considerando o contexto formativo de um curso de licenciatura em Letras, em que o objeto de estudo é o texto-enunciado, uma abordagem discursiva pode favorecer processos de ensino-aprendizagem que impliquem o sujeito e promovam a ressignificação de princípios axiológicos relacionados às questões de raça/racismo. Para a consecução deste trabalho, partimos de uma apresentação de pressupostos epistemológicos defendidos pelo Círculo de Bakhtin, com vistas a evidenciar a relevância de um currículo que contemple uma perspectiva dialógica. Para ilustrar a discussão dos pressupostos epistemológicos, utilizamos alguns excertos de atividades realizadas por alunos de graduação em um curso de extensão que teve por objetivo explorar questões relacionadas à (des)igualdade racial. A partir das discussões empreendidas, procuramos demonstrar que uma formação profissional para a docência demanda não somente a seleção de conteúdos e atividades, mas também, atos responsivos para a constituição de sujeitos éticos e sensíveis às demandas da sociedade.  Palavras-chave: Currículo.

(Des)encontros para um currículo afrocentrado no ensino de língua portuguesa na educação profissional técnica de nível médio integrada ao Ensino Médio
Authors: Santos Mariana Fernandes dos , Valadares Flavio Biasutti , Macedo Yuri Miguel
Published: October 2019

Os processos de construção dos currículos na educação brasileira, historicamente, têm como referência o centralismo epistemológico eurocêntrico e ocidental institucionalizado e naturalizado desconsiderando as diferenças culturais. No que concerne ao currículo da língua portuguesa nos diversos níveis de ensino, predomina o monolinguismo, monoculturalismo, referência literária colonialista, protagonismo de apenas uma etnia, purismo linguístico, entre outros aspectos que ocasionaram o racismo cultural, instaurando a normatização e limitação de sentidos e significados das práticas linguageiras no ensino de língua portuguesa na educação básica. Diante disso, vemos a importância de problematizações em torno dessa realidade, em especial, quando se trata da educação básica profissional (Ensino Médio Integrado ao Técnico), considerando a necessidade do enfrentamento que há contra as práticas educativas tecnicistas, consolidadas em muitas das instituições que ofertam esses cursos. Nessa perspectiva, neste artigo, nos ocupamos do objetivo de analisar como se constitui o currículo de Língua portuguesa (LP) no curso Ensino Médio Integrado ao Técnico em Informática do Instituto Federal de Educação, Ciência e Tecnologia da Bahia (IFBA), Campus Eunápolis, em relação à promoção da igualdade racial, tendo como referenciais teórico-metodológicos os estudos de base intercultural e de(s) colonial. Os resultados demonstram que o currículo de LP estudado não contempla nem mesmo o marco legal para promoção da igualdade racial. Nesse aspecto, ressaltamos a necessidade constante de problematizar os currículos escolares, considerando o paradigma da afrocentricidade como um caminho para via intercultural, de descolonização epistemológica, de descentralidade colonial e, ao mesmo tempo, a proposição de outras formas de vivências com as diferenças culturais. Palavras-chave: Ensino de Língua Portuguesa. Descolonialidades. Afrocentricidade.

Published: October 2019

Este estudo tem como objetivo verificar se os estudantes com Síndrome de Down de um município da Fronteira oeste do RS participam das aulas de Educação Física, descrevendo como ocorre esta participação, e de que forma os pais/responsáveis e os professores de Educação Física desses alunos entendem e contribuem para o processo inclusivo dos mesmos, nas aulas de Educação Física escolar. Para tanto, participaram do estudo quatro estudantes com Síndrome de Down de duas escolas públicas e uma privada, quatro pais/responsáveis e três professoras de Educação Física. Foram realizadas entrevistas semiestruturadas com todos os participantes do estudo, bem como, empregada observação sistemática das aulas, de forma direta e não participante, para aqueles estudantes que participavam das aulas de Educação Física. Verificou-se que apenas duas estudantes, matriculadas em instituição privada de ensino, frequentam as aulas de Educação Física, mas essa participação não ocorre de forma efetiva. Ainda, identificou-se que a abordagem do professor de Educação Física e a escolha dos conteúdos, contribuem para a não participação do estudante com Síndrome de Down nas aulas de Educação Física escolar. Frente à realidade encontrada, percebe-se que ainda existem muitas barreiras para que a participação de estudantes com Síndrome de Down nas aulas de Educação Física aconteça de forma efetiva. Palavras-chave: Educação Física escolar.

Published: October 2019

Neste artigo, nosso propósito é analisar aspectos de como a Matemática se configurava nos cursos de Ciências que, no sul do Mato Grosso Uno, tinham por finalidade formar professores. Para a discussão, recorremos às compreensões resultantes de duas teses de Doutorado, uma das quais, tematiza as Licenciaturas em Ciências e em Matemática, no estado de Mato Grosso do Sul, nos campus da UEMT – Universidade Estadual de Mato Grosso e da FADAFI - Faculdade de Filosofia Dom Aquino, em torno da década de 1970; enquanto a outra estuda as Licenciaturas Parceladas de Ciências e as Licenciaturas em Regime Parcelado de Ciências – Habilitação em Matemática, implantadas, respectivamente, nas décadas de 1970 pela UEMT, e em 1990 pela UFMS – Universidade Federal de Mato Grosso do Sul. O estudo dessas produções considera o sul do Mato Grosso Uno e sua realidade sociocultural e política, permitindo observar, dentre uma pluralidade de subtemas de discussões, a Matemática presente nessas modalidades de formação de professores. Ressaltamos, assim, que as disciplinas relativas à Matemática, nessas distintas modalidades de ensino, seguiam praticamente as mesmas disposições e pressupostos e, com uma mesma nomenclatura e carga horária, eram efetivadas de modos muito distintos nos processos de formação. Palavras-chave: Formação de professores de Matemática.

Theory and practice: between dichotomies and relations in the formation of English teachers
Authors: Boa Sorte Paulo , Silva Nayara Stefanie Mandarino
Published: October 2019

Many teachers in pre-service programs see knowledge about approaches, methods, and English teaching techniques – formulated and disseminated by specialists –  as distant from reality or impossible to be developed. In order to understand better this problem, this research aims to analyze what is meant by the terms "theory" and "practice" and the possible relationships between them in the context of pre-service English teachers’ development. From that point of view, it may be observed new and/or different views about how teachers are formed and how much this formation has prioritized contact with theories, practices, and their relationships. The theoretical bases are Freire ([1968] 2011), Rajagopalan (1984), Pereira (1988), Kincheloe (1997), Japiassu & Marcondes (2001), Pennycook (2010) and Vieira-Abrahão (2010). Data was collected through semi-structured interviews (Lüdke and André, 1996; RIZZINI, 1999). The results indicate that student teachers understand these conceptions as opposites and that, in many cases, these concepts are not completed or are difficult to complete, rejecting them as a unity. Keywords: Theory. Practice. Teacher Development.
“Lembro-me de querer andar durinho, como se diz que homem deve ser”: a construção do corpo gay na escola
Authors: Rios Pedro Paulo Souza , Dias Alfrancio Ferreira , Brazão José Paulo Gomes
Published: October 2019

Este estudo tem como objetivo refletir acerca da construção de masculinidades/homossexualidades nas trajetórias de professores gays, egressos dos cursos de licenciatura em Pedagogia, Matemática e Biologia do Campus VII, da Universidade do Estado da Bahia – UNEB, tendo em vista os processos de construção de gênero e sexualidade, em suas trajetórias de vida, formação acadêmica e, exercício profissional. Desenvolvemos uma pesquisa qualitativa com descrição e interpertação das narrativas (auto)biográficas, produzidas por seis professores gays. Dessas narrativas emergiram as produções educativas heterossexistas e normatizadoras que visam transformar crianças em adultos. O poder disciplinar sobre os corpos no contexto escolar é disseminado por práticas educativas instituídas que hierarquizam, regulamentam e padronizam espaços, atividades pedagógicas, cores, modos de se comportar, brinquedos e, brincadeiras, como sendo adversativas, ou para meninos ou para meninas. Contudo, os corpos gays impõem-se ao problematizarem questões não passíveis de discussão. Os sujeitos desenvolveram estratégias de enfrentamento das normas heterossexistas. Isso resultou numa nova concepção do que é ser estudante, assumindo uma postura queer. Ser queer funcionou como instrumento pedagógico, para permanecer na escola, enquanto um direito social para resolver os atos preconceituosos e excludentes. Palavras-chave: Narrativas (Auto)biográficas. Gênero. Homossexualidades. Performatividade. Professores.
Sócrates não gostava do método de Estudo de Casos: por que você gostaria?
Authors: Flyvbjerg Bent
Published: October 2019

O método de estudo de caso visa desenvolver o rico conhecimento do contexto, do envolvimento e da experiência necessários para se tornar um especialista. Por este motivo, o método é mais eficiente como um instrumento de aprendizagem do que métodos didáticos voltados para a teoria de Sócrates-Platão baseada em regras. Neste artigo argumentamos que somente o conhecimento detalhado de casos torna possível a ascensão de principiante para especialista. A teoria é, geralmente, importante para a educação profissional e prática, mas se as pessoas fossem treinadas exclusivamente através de regras e conhecimentos independentemente do contexto, elas sempre seriam principiantes — saberiam somente as respostas dos livros e funcionariam como computadores ou como burocratas, mecanicamente.
Modifiable Areal Unit Problem: the issue of determining the relationship between microparameters and a macroparameter
Authors: Pietrzak Michał Barnard
Published: October 2019

Research background: One of the issues considered by economists such as Tinbergen (1939), Klein (1946), May, (1946), Theil (1965), Pawłowski (1969), Bołt et al. (1985) was to determine the mechanism of transition between the results of microeconomics and the theory of macroeconomics. As part of this research, Pawłowski (1969) raised the problem of establishing the relationship between microparameters and a macroparameter. In the presented article, Pawłowski's problem was expanded to include spatial economic research, where micro-dependencies and spatial macro-dependencies were analysed.
Purpose of the article: The purpose of the article is to establish the relationship between the microparameters set for SGM agricultural macroregions and the macroparameter referring to the whole area of Poland, where the parameters describe the economic dependencies regarding the impact of the size of farms in established region on their technical equipment. In the study, the economic relationships analysed in the case of individual SGM agricultural macroregions were defined as spatial micro-dependencies, and in the case of the entire area of Poland as spatial macro-dependencies.
Methods: The methodological part of the article describes the concepts of Modifiable Areal Unit Problem, causal homogeneity of spatial data, homogeneous system of sets of areal units, area and sub-areas of conclusions. The concepts of micro-dependencies and spatial macro-dependencies are presented. Basic equations allowing to determine the evaluation of the spatial macroparameter as a linear combination of spatial microparameters were also presented.
Findings & Value added: In the first stage of the study, spatial micro-dependencies were identified for subsequent SGM agricultural macroregions. In the second stage of the study, the relationship between spatial microparameters for single macroregions and the spatial macroparameter for Poland was determined. Establishing the relationship allowed to determine the macroparameter estimate for the whole area of Poland.

Published: October 2019

Research background: The issue of predicting the financial situation of companies is a relatively young field of economic research. Its origin dates back to the 30's of the 20th century, but constant research in this area proves the currentness of this topic even today. The issue of predicting the financial situation of a company is up to date not only for the company itself, but also for all stakeholders.
Purpose of the article: The main purpose of this study is to create new prediction models by using the method of decision trees, in achieving sufficient prediction power of the generated model with a large database of real data on Polish companies obtained from the Amadeus database.
Methods: As a result of the development of artificial intelligence, new methods for predicting financial failure of the company have been introduced into financial prediction analysis. One of the most widely used data mining techniques in this field is the method of decision trees. In the paper, we applied the CART and CHAID approach to create a model of predicting the financial difficulties of Polish companies.
Findings & Value added: For the creation of the prediction model, a total of 37 financial and economic indicators of Polish companies were used. The resulting decision trees based prediction models for Polish companies reach a prediction power of more than 98%. The success of the classification for non-prosperous companies is more than 83%. The created decision tree-based prediction models are useful mainly for predicting the financial difficulties of Polish companies, but can also be used for companies in another country.
POLÍTICA, GEOECONOMÍA, ECONOMÍA Y CULTURA. “Influencias en el mundo actual”.
Authors: Buelvas Parra John Arturo
Published: October 2019

Hablar de política, geoeconomía, economía y cultura, hace referencia a variables que tienen influencia en el desarrollo de pueblos y naciones. Cuando un pueblo cuenta con políticas claras y se tiene la voluntad para darle un sentido orientado mejorar la calidad de vida de sus habitantes, entonces es cuando se está hablando de desarrollo propiamente. Pero esto se logra con buenas políticas educativas, buenos sistemas de comunicación que llegue a toda la población. Las crisis son situaciones que pueden ser tomadas como oportunidades para mejorar, y que incentivan a generar crecimiento, pero hoy en día donde el mundo entró en un proceso de globalización, en el comercio, en los negocios, en la misma cultura, está obligando a muchos países a repensar sus políticas internas para ajustarlas a los requerimientos que estos cambios traen.  Lo cierto es, que en este proceso de cambio, lo que debe importar es que lo que se pretenda hacer,  se haga en beneficio de la población, para que está genere desarrollo en pro de una mejor calidad de vida y se pueda satisfacer sus necesidades apremiantes;  entonces si se estaría en un camino seguro para la existencia y perdurabilidad del ser humano.
Bilateral radial and ulnar fractures in a red kangaroo (Macropus rufus)

Published: October 2019

CASE DESCRIPTION

An 11-month-old sexually intact male red kangaroo (Macropus rufus) was examined because of bilateral radial and ulnar fractures.

CLINICAL FINDINGS

Radiography of the forelimbs revealed bilateral, short oblique fractures in the proximal to mid diaphyses of the radii and ulnae. Fractures were overriding and moderately displaced. Wider than expected gaps were evident in the humeroulnar and humeroradial joints bilaterally. Although several physes remained open, no proximal radial physis was radiographically evident.

TREATMENT AND OUTCOME

Dual bone fixation was performed bilaterally, and dynamic luxation of the left radial head was identified and stabilized intraoperatively. Although satisfactory function of both forelimbs was evident at 8 weeks and 26 months after surgery, a persistent gait abnormality affecting the right forelimb was noted. Twenty-six months after surgery, radiography revealed bilateral proximal radial physes and resolution of the abnormally wide gaps in the humeroradial and humeroulnar joints. Despite dual bone fixation, synostoses formed bilaterally and may have contributed to the persistent lameness in the kangaroo's right forelimb.

CLINICAL RELEVANCE

Veterinarians treating kangaroos should be aware of difficulties in determining skeletal maturity and planning fracture stabilization because of potential differences in skeletal growth and fracture healing, compared with other species. We described critical issues observed in the treatment and outcome of the kangaroo of the present report and provided lessons learned as well as potential explanations of these issues to facilitate future treatment of kangaroos with forelimb fractures.
The Effect of Elastic and Inelastic Scattering on Electronic Transport in Open Systems

Published: October 2019

The purpose of this study is to apply the distribution function formalism to the problem of electronic transport in open systems, and to numerically solve the kinetic equation with a dissipation term. This term is modeled within the relaxation time approximation and contains two parts, corresponding to elastic or inelastic processes. The collision operator is approximated as a sum of the semi-classical energy dissipation term and the momentum relaxation term, which randomizes the momentum but does not change the energy. As a result, the distribution of charge carriers changes due to the dissipation processes, which has a profound impact on the electronic transport through the simulated region discussed in terms of the current–voltage characteristics and their modification caused by the scattering. Measurements of the current–voltage characteristics for titanium dioxide thin layers are also presented, and compared with the results of numerical calculations.
Using Neural Networks with data Quantization for time Series Analysis in LHC Superconducting Magnets
Authors: Wielgosz Maciej , Skoczeń Andrzej
Published: October 2019

The aim of this paper is to present a model based on the recurrent neural network (RNN) architecture, the long short-term memory (LSTM) in particular, for modeling the work parameters of Large Hadron Collider (LHC) super-conducting magnets. High-resolution data available in the post mortem database were used to train a set of models and compare their performance for various hyper-parameters such as input data quantization and the number of cells. A novel approach to signal level quantization allowed reducing the size of the model, simplifying the tuning of the magnet monitoring system and making the process scalable. The paper shows that an RNN such as the LSTM or a gated recurrent unit (GRU) can be used for modeling high-resolution signals with the accuracy of over 0.95 and a small number of parameters, ranging from 800 to 1200. This makes the solution suitable for hardware implementation, which is essential in the case of monitoring the performance critical and high-speed signal of LHC superconducting magnets.
Event–Based Feedforward Control of Linear Systems with input Time–Delay
Authors: Rodríguez Carlos , Aranda-Escolástico Ernesto , Guinaldo María , Guzmán José Luis , Dormido Sebastián
Published: October 2019

This paper proposes a new method for the analysis of continuous and periodic event-based state-feedback plus static feed-forward controllers that regulate linear time invariant systems with time delays. Measurable disturbances are used in both the control law and triggering condition to provide better disturbance attenuation. Asymptotic stability and L2-gain disturbance rejection problems are addressed by means of Lyapunov–Krasovskii functionals, leading to performance conditions that are expressed in terms of linear matrix inequalities. The proposed controller offers better disturbance rejection and a reduction in the number of transmissions with respect to other robust event-triggered controllers in the literature.

Background and objectives. During the two past decades, a new therapeutic approach to ovarian cancer (OC) has been developed. This combines cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). However, almost no data exist regarding the utility of biomarkers of morphological heterogeneity as prognostic factors in such patients.

Methods. A retrospective study of the effectiveness of CRS and HIPEC was carried out in 59 patients with ovarian cancer. Biomarkers of morphological heterogeneity of OC were studied as prognostic factors: OC pathogenic types (based on the identification of р53 mutated gene protein expression) and homologous recombination deficit (basing on the identification of BRCA 1 gene expression status).

Results. The survival of patients reliably differed with the division into two pathogenetic OC types established by immunohistochemistry: the median disease-free survival of type I OC patients was 14±1.7 months, type ІІ – 8±1.6 months (р = 0.007); the median overall survival of type I OC patients was 23.5±6.7 months, type ІІ – 12±1.9 months (р = 0.017). The median overall survival of patients with the somatic mutation of BRCA 1 gene and complete cytoreduction was 22±4.8 months, and without the somatic mutation of BRCA 1 gene – 12±3.3 months (р = 0.047).

Conclusions. These data demonstrate that identification of the pathogenetic type of OC and BRCA 1 status may be useful for the personalized therapy of ovarian cancer patients treated with CRS/HIPEC.
