    Functional Verification of Digital Systems Using Meta-Heuristic Algorithms

    Get PDF
    Trends in technological developments, such as autonomous vehicles, home automation, connected cars, IoT, etc., are based on integrated systems or application-specific integrated circuits with high capacities, where these systems require even more complex devices. Thus, new techniques to design more secure systems in a short time in the market are needed. At this point, verification is one of the highest costs in the manufacturing stage and most expensive in the design process. To reduce the time and cost of the verification process, artificial intelligence techniques based on the optimization of the coverage of behavioral areas have been proposed. In this chapter, we will describe the main techniques used in the functional verification of digital systems of medium complexity, focusing especially on meta-heuristic algorithms such as particle swarm optimization, genetic algorithms, and so on. Several results are presented and compared, where the opportunity areas will be described

    Mitochondrial Diabetes in Children: Seek and You Will Find It

    Get PDF
    Maternally Inherited Diabetes and Deafness (MIDD) is a rare form of diabetes due to defects in mitochondrial DNA (mtDNA). 3243 A>G is the mutation most frequently associated with this condition, but other mtDNA variants have been linked with a diabetic phenotype suggestive of MIDD. From 1989 to 2009, we clinically diagnosed mitochondrial diabetes in 11 diabetic children. Diagnosis was based on the presence of one or more of the following criteria: 1) maculopathy; 2) hearing impairment; 3) maternal heritability of diabetes/impaired fasting glucose and/or hearing impairment and/or maculopathy in three consecutive generations (or in two generations if 2 or 3 members of a family were affected). We sequenced the mtDNA in the 11 probands, in their mothers and in 80 controls. We identified 33 diabetes-suspected mutations, 1/33 was 3243A>G. Most patients (91%) and their mothers had mutations in complex I and/or IV of the respiratory chain. We measured the activity of these two enzymes and found that they were less active in mutated patients and their mothers than in the healthy control pool. The prevalence of hearing loss (36% vs 75–98%) and macular dystrophy (54% vs 86%) was lower in our mitochondrial diabetic adolescents than reported in adults. Moreover, we found a hitherto unknown association between mitochondrial diabetes and celiac disease. In conclusion, mitochondrial diabetes should be considered a complex syndrome with several phenotypic variants. Moreover, deafness is not an essential component of the disease in children. The whole mtDNA should be screened because the 3243A>G variant is not as frequent in children as in adults. In fact, 91% of our patients were mutated in the complex I and/or IV genes. The enzymatic assay may be a useful tool with which to confirm the pathogenic significance of detected variants

    Al cierre de la edición número 37 de la Revista Temas Socio- Jurídicos, registramos la desaparición de la profesora de la Universidad Nacional de Colombia Virginia Gutierrez De Pineda, antropóloga santandereana, profesora, quien en varias oportunidades honró con su presencia y su prestancia a la Universidad Autónoma de Bucaramanga, en especial la Maestría en Derecho de Familia, en la cual atendió el área relacionada con los conflictos entre los géneros, la pareja y la familia. Gus enseñanzas, su acción vital, su permanente indagación de la realidad del país han de servir de ejemplo a quienes deseen seguir la senda de la ciencia y conquistar horizontes de conocimiento. Como homenaje a esta mujer pionera, la revista publica una de sus últimas conferencias pronunciadas en la Universidad, denominada el conflicto en la relación de los géneros. Dos escritos salidos de la pluma del profesor Alfonso Gómez Gómez, el primero sobre el resurgimiento de las provincias, el segundo sobre las Asambleas Departamentales, incitan a la reflexión cobre la necesidad de una reconfiguración de la estructura político-administrativa de las regiones en el País. Proseguimos con la divulgación del ensayo sobre Institutos Jurídicos Básicos, la segunda parte, donde se exponen los fundamentos económico-sociales de las instituciones jurídicas y sus expresiones abstractas en el orden de los conceptos.At the close of the 37th edition of the Socio-Legal Issues Magazine, we recorded the disappearance of the professor at the National University of Colombia, Virginia Gutierrez De Pineda, an anthropologist from Santander, professor, who on several occasions honored the Autonomous University of Bucaramanga, especially the Master's Degree in Family Law, in which he dealt with the area related to conflicts between genders, couples and family. Gus teachings, his vital action, his permanent investigation of the reality of the country must serve as an example to those who wish to follow the path of science and conquer horizons of knowledge. As a tribute to this pioneering woman, the magazine publishes one of her last lectures given at the University, called the conflict in the relationship between genders. Two writings from the pen of Professor Alfonso Gómez Gómez, the first on the resurgence of the provinces, the second on the Departmental Assemblies, encourage reflection on the need for a reconfiguration of the political-administrative structure of the regions in the Country . We continue with the disclosure of the essay on Basic Legal Institutes, the second part, where the socio-economic foundations of legal institutions and their abstract expressions in the order of concepts are exposed

    [Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. [Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. [Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. [Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group
