1. Harmonic curves and the beauty of Projective Geometry

Author

Abreu, José Luis and Bracho, Javier

Subjects
Mathematics - History and Overview, 51A05, 97G10, 97G40, 51A30
Abstract

The purpose of this paper is to present projective geometry in a synthetic, visual and intuitive style through the central notion of harmonicity which leads to harmonic curves. This presentation includes new results, unpublished proofs of some classic theorems and a slight reformulation of its axiomatics., Comment: The 11 figures are dynamic and can be viewed at: https://arquimedes.matem.unam.mx/harmonic curves/scenes.html

Abstract

No século da independência, do Império e da República, a existência do sistema esclavagista marcou decisivamente a história do Brasil, condicionando as mentalidades e o futuro da nação. Como tal, perante uma realidade insofismável, este trabalho procura demonstrar como no século negro a escravidão, a abolição, as relações entre senhores e escravos se estabeleceram, trazendo para a cena literária romances, contos, crónicas, de referências da literatura do Brasil, quase todas de autores bem conhecidos: Maria Firmina dos Reis, Joaquim Manuel de Macedo, Bernardo Guimarães, Aluísio Azevedo, e, não menos importante, Machado de Assis. Sob o manto da segurança do fazendeiro, do preconceito da cor, da sentimentalidade, da crítica ao desejo de notoriedade burguesa, da denúncia da violência escravocrata, estes escritores, uns de forma mais consciente e crítica do que outros, evidenciando uma leitura histórica, social e política que problematiza as estruturas de domínio da sociedade brasileira e a forma como exercem a sua autoridade, escreveram e conceberam, indubitavelmente, a história brasileira de oitocentos

10. Pivot Selection for Median String Problem

Author

Mirabal, Pedro, Abreu, José, and Pedreira, Oscar

Subjects
Computer Science - Data Structures and Algorithms
Abstract

The Median String Problem is W[1]-Hard under the Levenshtein distance, thus, approximation heuristics are used. Perturbation-based heuristics have been proved to be very competitive as regards the ratio approximation accuracy/convergence speed. However, the computational burden increase with the size of the set. In this paper, we explore the idea of reducing the size of the problem by selecting a subset of representative elements, i.e. pivots, that are used to compute the approximate median instead of the whole set. We aim to reduce the computation time through a reduction of the problem size while achieving similar approximation accuracy. We explain how we find those pivots and how to compute the median string from them. Results on commonly used test data suggest that our approach can reduce the computational requirements (measured in computed edit distances) by $8$\% with approximation accuracy as good as the state of the art heuristic.

Abstract

Introduction: Type 2 diabetes mellitus (DM2) is defined as a metabolic disorder characterized by chro-nically elevated blood glucose levels. DM2 represents the paradigm of chronic diseases in which there is a close association between family and environmental factors. Therefore, the purpose of this study is to deter-mine the association of the risk of developing DM2 and non-illicit toxic habits in patients residing in a rural community in Peravia, Dominican Republic. Such habits include alcohol, coffee and tea.Methodology: Observational, cross-sectional, analytical and prospective study. A questionnaire was applied, anthropometric data was collected, and capillary glucose was determined in the study sample (n=304).Results: the prevalence of presenting a high risk of developing DM2 in the population is 35.5%, while the prevalence of presenting low risk is 64.5%. Regarding toxic habits, there was no positive correlation between tea consumption and the development of DM2. However, this result differed between consumption of coffee and alcohol.Conclusions: the inhabitants of Salinas have a low risk of developing DM2 but are subject to modifiable risk factors that increase said prevalence., Introducción: la diabetes mellitus tipo 2 (DM2) se define como un trastorno metabólico caracterizado por niveles de glucosa en sangre crónicamente elevados. La DM2 representa el paradigma de las enfermedades crónicas en las que existe una estrecha asociación entre factores familiares y ambientales. Por este motivo, este estudio tiene como finalidad determinar la asociación del riesgo a desarrollar DM2 y los hábitos tóxicos no ilícitos en pacientes que residen en una comunidad rural de Peravia, República Dominicana. Tales incluyen: alcohol, café y té.Metodología: Estudio observacional, transversal, analí-tico y prospectivo. Se aplicó cuestionario, recolectaron datos antropométricos y se determinó glucosa capilar a la muestra (n=304).Resultados: la prevalencia a presentar un alto riesgo a desarrollar DM2 en la población es de 35.5%, mientras que la prevalencia a presentar riesgo bajo es de 64.5%. En cuanto a hábitos tóxicos, no existió correlación posi-tiva entre consumo de té y desarrollo de DM2. Sin embargo, sí entre el consumo de café y alcohol.Conclusiones: los habitantes de salinas presentan un bajo riesgo a desarrollar DM2, pero utilizan factores de riesgos modificables que aumentan la prevalencia a DM2
