    In this document, we briefly describe the main contribution to the deliverable on experimenting with the implementation of most of the calculi considered in the project. First, we describe how two well known calculi for mobile processes KLAIM and Dπ have been implemented on the top of IMC. We then describe the implementation of the MiKO programming language, an instance of the parametric calculus introduced in the WP1 with the TyCO calculus as the content of the membrane itself. After this, we outline the description of the implementation of the abstract machine for an instance of the Kell Calculus that dedicates particular attention to the proof of its correctness. Our presentation ends with a discussion of the problem of implementing security membranes on the top of an execution platform

    Application of the Asymptotic Iteration Method to a Perturbed Coulomb Model

    Full text link
    We show that the asymptotic iteration method converges and yields accurate energies for a perturbed Coulomb model. We also discuss alternative perturbation approaches to that model.Comment: 9 pages, 2 figures, 1 tabl

    Trace-metaldynamics in response of increase CO<sub>2</sub> and iron availability in a coastal mesocosm experiment

    A mesocosm experiment was performed in the Raunefjord (Norway) to study changes in dissolved Cu (dCu) and Fe (dFe), and in the elemental composition of particles during an Emiliania huxleyi dominated bloom. The CO2 treatments consisted of present (LC; 390 ppmV) and predicted levels (HC; 900 ppmV) and iron conditions were created with the addition of the siderophore desferoxamine B (DFB). Our results showed the DFB addition enhanced the solubility of Fe in this fjord environment. Initially, dFe was comparable among treatments but after the addition, the HC and/or +DFB treatments presented higher levels and finally, the only ones maintaining high dFe were the +DFB treatments. Unlike dCu presented indistinguishable levels in all mesocosms over time. Particulate metals were normalised to P and Al to evaluate the relative influence of biotic and abiotic sources. The Fe:P ratios decreased with time and compared to published phytoplankton ratios suggest Fe storage. On the other hand, Fe:Al ratios were relatively closer to the crustal ratios suggesting that the abiotic source was more important for this metal. Trends for other metals will be discussed.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

    Geometric structures on loop and path spaces

    Full text link
    Is is known that the loop space associated to a Riemannian manifold admits a quasi-symplectic structure. This article shows that this structure is not likely to recover the underlying Riemannian metric by proving a result that is a strong indication of the "almost" independence of the quasi-symplectic structure with respect to the metric. Finally conditions to have contact structures on these spaces are studied.Comment: Final version. To appear in Proceedings of Math. Sci. Indian Academy of Science

    Congenital Solitary Functioning Kidney and Other Associated Congenital Malformations

    Introduction: Congenital solitary functioning kidney (CSFK) is associated to other congenital anomalies. Most of them involve urogenital tract, cardiac, skeletal and central nervous system. There are also some syndromes associated to renal malformations. Objective: To determine the prevalence of associated malformations in children with CSFK. Material and methods: We reviewed 134 electronic processes of children with CFSK followed in a terciary department of paediatric nephrology between 2012 and 2016. Results: Ages ranged from neonatal period to 18 years old (6.6±4.4 years). Prenatal diagnosis of solitary kidney was made in 89 cases (66.4%), and agenesia was the etiology in 33.5%. We found 41 children with at least one more malformation (30.6 %). One quarter of children with postnatal diagnosis of CSFK (7/28) had other anomalies. From all children with diagnosis of agenesia, 80% had at least one more malformation, whereas only 30% of other CSFK’s etiology had other anomaly indentified. Urological anomalies were the most frequent (34.1%); however, 27/41 children (65.8%) had at least one malformation of other system, without an urological anomaly. Gastrointestinal anomalies were identified 21.9%, cardiovascular anomalies 19.5%, genital malformations in 19.5%, neurological anomalies in 14.6% and other organ anomalies in 17%. The non-urological congenital malformation more frequent was single umbilical artery (12.2%). Fourteen children (34.1%) had their anomalies included in a syndrome, all them associated with renal anomalies in previous studies. Chronic kidney disease was seen in five of 134 children, three of which with another malformation. Conclusions: This study intends to recall that CSFK may not be the only congenital malformation in a child. It also highlights that there are other anomalies besides urological tract that may be present and must be investigated, especially if there is a diagnosis of true renal agenesia. A good prenatal care and careful follow-up of children with CSFK are essential.info:eu-repo/semantics/publishedVersio
