Embedding, evolution, and validation of model-driven spreadsheets

This paper proposes and validates a model-driven software engineering technique for spreadsheets. The technique that we envision builds on the embedding of spreadsheet models under a widely used spreadsheet system. This means that we enable the creation and evolution of spreadsheet models under a spreadsheet system. More precisely, we embed ClassSheets, a visual language with a syntax similar to the one offered by common spreadsheets, that was created with the aim of specifying spreadsheets. Our embedding allows models and their conforming instances to be developed under the same environment. In practice, this convenient environment enhances evolution steps at the model level while the corresponding instance is automatically co-evolved.Finally,wehave designed and conducted an empirical study with human users in order to assess our technique in production environments. The results of this study are promising and suggest that productivity gains are realizable under our model-driven spreadsheet development setting.

Búsqueda de marcadores de evolución y tratamiento en la miocardiopatía por Enfermedad de Chagas. Searching for indicators of evolution and treatment of Chagas disease miocardiopathy.

El 30 por ciento de personas infectadas con T. cruzi desarrollará una cardiopatía chagásica de expresión clínica variada. Por esta razón es relevante identificar marcadores genéticos y de evolución de la miocardiopatía a fin de clasificar a los pacientes, acorde al grado de riesgo de desarrollar la enfermedad, así como es necesario investigar sobre mejores tratamientos.Los marcadores genéticos de riesgo (polimorfismos relacionados con enfermedades) colaboran identificando genes involucrados en enfermedades poligénicas. Analizaremos SNPs (single nucleotide polymorphism) localizados en zonas potencialmente funcionales de los genes de endotelina-1, su receptor A, de SOD-Mn, y de TNF alfa, factores que intervendrían en la expresión de severidad de la cardiopatía.El corazón es un órgano altamente dependiente de la energía provista por las mitocondrias y éstas son blanco de mediadores inflamatorios que se producen con el ingreso del parásito; por eso estudiaremos en corazones de ratones y de pacientes chagásicos las alteraciones genéticas, morfológicas y funcionales mitocondriales con el fin de determinar lesiones y evolución de las mismas.Existen controversias en tratar la Enfermedad de Chagas fuera de la etapa aguda por la toxicidad de las drogas. La clomipramina antidepresivo usado en siquiatría, demostró impedir la evolución de la infección aguda en modelos experimentales; proponemos el tratamiento con benznidazol a la mitad de la dosis habitual asociada a clomipramina en bajas concentraciones en modelos experimentales en el estadío crónico. Estos resultados aportarán a la fisiopatogenia de la miocardiopatía chagásica, al contar con marcadores de evolución, severidad y de probable riesgo de desarrollar la cardiopatía y serán un aporte a la prevención y nuevos tratamientos.

Quantifying rates of landscape evolution and tectonic processes by thermochronology and numerical modeling of crustal heat transport using PECUBE

PECUBE is a three-dimensional thermal-kinematic code capable of solving the heat production-diffusion-advection equation under a temporally varying surface boundary condition. It was initially developed to assess the effects of time-varying surface topography (relief) on low-temperature thermochronological datasets. Thermochronometric ages are predicted by tracking the time-temperature histories of rock-particles ending up at the surface and by combining these with various age-prediction models. In the decade since its inception, the PECUBE code has been under continuous development as its use became wider and addressed different tectonic-geomorphic problems. This paper describes several major recent improvements in the code, including its integration with an inverse-modeling package based on the Neighborhood Algorithm, the incorporation of fault-controlled kinematics, several different ways to address topographic and drainage change through time, the ability to predict subsurface (tunnel or borehole) data, prediction of detrital thermochronology data and a method to compare these with observations, and the coupling with landscape-evolution (or surface-process) models. Each new development is described together with one or several applications, so that the reader and potential user can clearly assess and make use of the capabilities of PECUBE. We end with describing some developments that are currently underway or should take place in the foreseeable future. (C) 2012 Elsevier B.V. All rights reserved.
