XVI International Congress of Control Electronics and Telecommunications: "Techno-scientific considerations for a post-pandemic world intensive in knowledge, innovation and sustainable local development"

Este título, sugestivo por los impactos durante la situación de la Covid 19 en el mundo, y que en Colombia lastimosamente han sido muy críticos, permiten asumir la obligada superación de tensiones sociales, políticas, y económicas; pero sobre todo científicas y tecnológicas. Inicialmente, esto supone la existencia de una capacidad de la sociedad colombiana por recuperar su estado inicial después de que haya cesado la perturbación a la que fue sometida por la catastrófica pandemia, y superar ese anterior estado de cosas ya que se encontraban -y aún se encuentran- muchos problemas locales mal resueltos, medianamente resueltos, y muchos sin resolver: es decir, habrá que rediseñar y fortalecer una probada resiliencia social existente - producto del prolongado conflicto social colombiano superado parcialmente por un proceso de paz exitoso - desde la tecnociencia local; como lo indicaba Markus Brunnermeier - economista alemán y catedrático de economía de la Universidad de Princeton- en su libro The Resilient Society…La cuestión no es preveerlo todo sino poder reaccionar…aprender a recuperarse rápido.This title, suggestive of the impacts during the Covid 19 situation in the world, and which have unfortunately been very critical in Colombia, allows us to assume the obligatory overcoming of social, political, and economic tensions; but above all scientific and technological. Initially, this supposes the existence of a capacity of Colombian society to recover its initial state after the disturbance to which it was subjected by the catastrophic pandemic has ceased, and to overcome that previous state of affairs since it was found -and still is find - many local problems poorly resolved, moderately resolved, and many unresolved: that is, an existing social resilience test will have to be redesigned and strengthened - product of the prolonged Colombian social conflict partially overcome by a successful peace process - from local technoscience; As Markus Brunnermeier - German economist and professor of economics at Princeton University - indicates in his book The Resilient Society...The question is not to foresee everything but to be able to react...learn to recover quickly.Bogot

Apert syndrome with preaxial polydactyly showing the typical mutation Ser252Trp in the FGFR2 gene

Apert syndrome with preaxial polydactyly showing the typical mutation Ser252 Trp in the FGFR2 gene: The Apert syndrome is characterized by craniosynostosis and syndactyly of hands and feet. Although most cases are sporadic, an autosomal dominant mode of inheritance is well documented. Two mutations in the FGFR2 gene (Ser252Trp and Pro253Arg) account for most of the cases. We report a patient with a rare form of Apert syndrome with polydactyly. The proposita has turribrachycephaly, complete syndactyly of 2nd to 5th digits ("mitten hands" and cutaneous fusion of all toes). The X-rays revealed craniosynostosis of the coronal suture and preaxial polydactyly of hands and feet with distal bony fusion. Molecular analysis found a C755G transversion (Ser252Trp) in the FGFR2 gene. Only eight patients with Apert syndrome and preaxial polydactyly have been reported and this is the first case In which molecular diagnosis is available. On the basis of the molecular findings in this patient, polydactyly should be considered part of the spectrum of abnormalities in the Apert syndrome. This assertion would establish the need for a new molecular classification of the acrocephalopolysyndactylies

First case reported of Turner syndrome and trisomy 14 chromosomal mosaicism in a patient

A 25-year-old woman with a mosaic 45,X/47XX,+14 karyotype is reported. She presented with short stature, short downward slanting palpebral fissures, broad nasal bridge, mouth with downturned corners, short and wide neck, swirly hyperpigmentation of the skin, and body asymmetry secondary to right hemihyperplasia. As there was an admixture of 45,X and trisomy 14, it was not possible to determine the cell line that had the greatest influence on the phenotype. We postulate that the proposita's survival until the third decade was owing to the chromosomal complementation of both aneuploidy cell lines. To our knowledge, this chromosomal association has not been previously reported. � 2008 Lippincott Williams & Wilkins, Inc

A review on assembly sequence planning and assembly line balancing optimisation using soft computing approaches

Assembly optimisation activities occur across development and production stages of manufacturing goods. Assembly Sequence Planning (ASP) and Assembly Line Balancing (ALB) problems are among the assembly optimisation. Both of these activities are classified as NP-hard. Several soft computing approaches using different techniques have been developed to solve ASP and ALB. Although these approaches do not guarantee the optimum solution, they have been successfully applied in many ASP and ALB optimisation works. This paper reported the survey on research in ASP and ALB that use soft computing approaches for the past 10years. To be more specific, only Simple Assembly Line Balancing Problem (SALBP) is considered for ALB. The survey shows that three soft computing algorithms that frequently used to solve ASP and ALB are Genetic Algorithm, Ant Colony Optimisation and Particle Swarm Optimisation. Meanwhile, the research in ASP and ALB is also progressing to the next level by integration of assembly optimisation activities across product development stages

Gaussians on the circle and quantum phase

Hemophilia A (HA) is one of the most common inherited bleeding disorders caused by FVIII gene mutations. Inversion of intron 22 (inv22) originates 50% of cases of severe HA and is a major risk factor for inhibitor development. Inversion of intron 1 (inv1) has been reported to occur in 2-3% of severe HA patients. We studied both inversions to determine their frequencies in Mexican patients with severe HA and to compare these data with other HA populations. The inv22 was evaluated as a risk factor for FVIII inhibitor development in severe HA patients. We studied 44 patients from 31 severe HA families for the detection of inv22 and 94 patients from 65 families to detect inv1. We used the subcycling long-distance PCR to detect inv22 and rapid PCR in duplex reactions to detect inv1. We found a frequency of 45% for the inv22 and no inv1-positive patients (0%). These frequencies were not statistically different from other populations, although haplotype analyses of FVIII gene and telomeric regions should be incorporated to explore population-specific variation of inv1 frequencies. Inv22-positive patients showed 1.88X higher risk for developing inhibitors with respect to patients carrying other severe mutations; however, this OR value was not significant. Our findings confirm inv22 as a hot-spot for severe HA and evidence the low frequency of inv1 in a Mexican population. The non-significant risk for developing inhibitors among inv22-positive patients agrees with the variety of genetic and non-genetic factors involved in such a complication.
