Novel Ruthenium-Silver PTA-Based Polymers and Their Behavior in Water
New coordination polymers based on two metal-containing moieties Ru–Ag are synthesized: Na[RuCpX(PTA)-μ-(PTA)-1κP:2κ2N-AgX2]∞ (X = Cl (1), Br (2), I (3)). Characterization is performed by NMR, UV-visible and FT-IR spectroscopy, optical-electron microscopy, and elemental analyses (C, H, N, S). Light scattering is employed to characterize the colloidal particles growth by polymer self-assembling. These structures are stable over a broad range of pH and exhibit thermally-driven swelling, thus resembling a typical thermosensitive hydrogel
Comparison of Thematic Maps Using Symbolic Entropy
Comparison of thematic maps is an important task in a number of disciplines. Map comparison has traditionally been conducted using cell-by-cell agreement indicators, such as the Kappa measure. More recently, other methods have been proposed that take into account not only spatially coincident cells in two maps, but also their surroundings or the spatial structure of their differences. The objective of this paper is to propose a framework for map comparison that considers 1) the patterns of spatial association in two maps, in other words, the map elements in their surroundings; 2) the equivalence of those patterns; and 3) the independence of patterns between maps. Two new statistics for the spatial analysis of qualitative data are introduced. These statistics are based on the symbolic entropy of the maps, and function as measures of map compositional equivalence and independence. As well, all inferential elements to conduct hypothesis testing are developed. The framework is illustrated using real and synthetic maps. Key word: Thematic maps, map comparison, qualitative variables, spatial association, symbolic entropy, hypothesis tests
Assessment of Generic Skills through an Organizational Learning Process Model
This contribution has been published in this repository with the permission of the publisher. This contribution was presented in WEBIST 2018 (http://www.webist.org/?y=2018) and has been published by SCITEPRESS in http://www.scitepress.org/PublicationsDetail.aspx?ID=y9Yt0eHt02o=&.The performance in generic skills is increasingly important for organizations to succeed in the current competitive environment. However, assessing the level of performance in generic skills of the members of an organization is a challenging task, subject to both subjectivity and scalability issues. Organizations usually lay their organizational learning processes on a Knowledge Management System (KMS). This work presents a process model to support managers of KMSs in the assessment of their individuals’ generic skills. The process model was deployed through an extended version of a learning management system. It was connected with different information system tools specifically developed to enrich its features. A case study with Computer Science final-year students working in a software system was conducted following an authentic learning approach, showing promising results.Visaigle Project (grant TIN2017-85797-R)
Feasibility and reliability of a Physical Fitness test battery in individuals with Down Syndrome
Background: Down syndrome (DS) is a genetic disorder that occurs because of an abnormal
division between cells that results in an extra copy of chromosome 21. Some studies show that
physical exercise in people with DS increases some cognitive capacities, such as memory, and improves
the quality of life. Aim: The main aim of this study was to perform an analysis of the reliability
and feasibility of the SAMU-Disability Fitness (DISFIT) battery in adults with DS. Methods: A
cross-sectional study with a test–retest design was performed in a maximum interval of 2 weeks in
37 subjects (11 women and 26 men) aged between 21 and 58 years old with DS. Eight field-based
fitness tests were proposed to assess the physical fitness (PF) of adults with DS: Body Mass Index
(BMI), Waist Circumference (WC), the Timed Up and Go test (TUG), the Deep Trunk Flexibility test
(DTF), the Hand Grip test (HG), the Timed Stand Test (TST), the 30-s Sit-Up (SUP) and the 6-Min
Walk Test (6MWT). Results: The intra-class correlation coefficient (ICC) in all the tests was good
and high (>0.80), except for the 6MWT, whose reliability was fair. Conclusion: The SAMU-DISFIT
battery is a reliable and feasible physical fitness battery which has been created with the purpose
of establishing tests which measure the four basic components of PF (flexibility, cardiorespiratory
fitness, musculoskeletal fitness and motor fitness) in adults with D
Acelerando los momentos de Zernike sobre Kepler
Este trabajo analiza las caracterÃsticas más avanzadas de la arquitectura Kepler de Nvidia,
principalmente el paralelismo dinámico para el lanzamiento de kernels desde la GPU
y la planificación de hilos con Hyper-Q. Posteriormente, ilustra diversas formas
de aprovecharlas en un código que computa los momentos de Zernike, y que admite
formulaciones directa y recursiva. Hemos podido asà contrastar las posibilidades
que ambas ofrecen para maximizar rendimiento en las nuevas GPUs, la primera desplegando
todo el paralelismo, y la segunda aumentando la intensidad aritmética gracias a la
amortización de resultados procedentes de iteraciones previas. Esto nos ha permitido
aumentar los factores de aceleración que ya logramos anteriormente con arquitecturas
Fermi frente a la versión C ejecutada en una CPU multicore de su misma generación.
Logramos también identificar la carga de trabajo crÃtica que necesita un código
para mejorar su ejecución en las nuevas plataformas dotadas de seis veces más núcleos
computacionales, y cuantificar la sobrecarga introducida por los nuevos mecanismos
de programación dinámica en CUDA.Universidad de Málaga. Campus de Excelencia Internacional AndalucÃa Tec
One hundred of cells generations connect the resistance to drugs and the replicative aging mechanisms
There are researchs that reveal a relationship between acquired resistance to antineoplastic drugs and aging.
Therefore, the identification of genes involved in senescence could have a potential therapeutic utility for the prediction and/or prevention of resistance to antineoplastic drugs.
The aim of this work is to study the relationship between replicative aging and acquired resistance to Cisplatin and Bleomycin in the yeast Saccharomyces cerevisiae.Universidad de Málaga. Campus de Excelencia Internacional AndalucÃa Tech
Proteomic analysis in wild type and cisplatin resistant yeast strain of saccharomyces cerevisiae
Research carried out in oncology has allowed the identification and characterization of molecular markers of resistance to antineoplastic drugs. It supposes a great advance and allows the administration of customized chemotherapies to patients.
The aim of this work is to carry out a proteomic analysis in the wild type strain and cisplatin resistant strain of Saccharomyces cerevisiae in order to look for possible markers of resistance, as well as the mechanisms involved.Universidad de Málaga.

Mechanisms of cross resistance between cisplatin and bleomycin in saccharomyces cerevisiae
Tumor cells can simultaneously acquire resistance against a diverse group of drugs. This phenomenon is called pleotropic resistance or multidrug resistance. This mechanism could explain the tumor resistance observed in chemotherapy treatments with multiple agents.
The aim of this work is to study possible mechanisms of cross resistance between Cisplatin and Bleomycin in Saccharomyces cerevisiae.Universidad de Málaga. Campus de Excelencia Internacional AndalucÃa Tech
