Análisis antracológico del yacimiento arqueológico de Peña Parda

Se presenta el estudio antracológico de los carbones recuperados en el abrigo de Peña Parda (Laguardia, Álava). El Nivel DI, de cronología calcolítica, es el de mayor fiabilidad estratigráfíca ya que el Nivel I incluye con bastante probabilidad restos vegetales de cronología reciente. En el Nivel III la madera más abundante es el boj (42%), seguido del tejo (33%). Otros taxones menores, presentes en porcentajes inferiores al 5% son: enebro, pino, gayuba/madroño, cornejo, fresno, hiedra, leguminosas, pomoidea, cerezo, roble/quejigo, grosellero y morrionera. Sugerimos que en el momento de ocupación del yacimiento las formaciones de bojedo debieron ser importantes en el entorno. La presencia del tejo debe responder a su capacidad de colonizar suelos delgados y rocosos

The SUSY partners of the QES sextic potential revisited

In this paper, the SUSY partner Hamiltonians of the quasi-exactly solvable (QES) sextic potential $V^{\rm qes}(x) = \nu\, x^{6} + 2\, \nu\, \mu\,x^{4} + \left[\mu^2-(4N+3)\nu \right]\, x^{2}$, $N \in \mathbb{Z}^+$, are revisited from a Lie algebraic perspective. It is demonstrated that, in the variable $\tau=x^2$, the underlying $\mathfrak{sl}_2(\mathbb{R})$ hidden algebra of $V^{\rm qes}(x)$ is inherited by its SUSY partner potential $V_1(x)$ only for $N=0$. At fixed $N>0$, the algebraic polynomial operator $h(x,\,\partial_x;\,N)$ that governs the $N$ exact eigenpolynomial solutions of $V_1$ is derived explicitly. These odd-parity solutions appear in the form of zero modes. The potential $V_1$ can be represented as the sum of a polynomial and rational parts. In particular, it is shown that the polynomial component is given by $V^{\rm qes}$ with a different non-integer (cohomology) parameter $N_1=N-\frac{3}{2}$. A confluent second-order SUSY transformation is also implemented for a modified QES sextic potential possessing the energy reflection symmetry. By taking $N$ as a continuous real constant and using the Lagrange-mesh method, highly accurate values ($\sim 20$ s. d.) of the energy $E_n=E_n(N)$ in the interval $N \in [-1,3]$ are calculated for the three lowest states $n=0,1,2$ of the system. The critical value $N_c$ above which tunneling effects (instanton-like terms) can occur is obtained as well. At $N=0$, the non-algebraic sector of the spectrum of $V^{\rm qes}$ is described by means of compact physically relevant trial functions. These solutions allow us to determine the effects in accuracy when the first-order SUSY approach is applied on the level of approximate eigenfunctions.Comment: 25 pages, 20 figure

SMART MOBILITY IN SMART CITIES

[EN] Cities are currently undergoing a transformation into the Smart concept, like Smartphones or SmartTV. Many initiatives are being developed in the framework of the Smart Cities projects, however, there is a lack of consistent indicators and methodologies to assess, finance, prioritize and implement this kind of projects. Smart Cities projects are classified according to six axes: Government, Mobility, Environment, Economy, People and Living. (Giffinger, 2007) The main objective of this research is to develop an evaluation model in relation to the mobility concept as one of the six axes of the Smart City classification and apply it to the Spanish cities. The evaluation was carried out in the 62 cities that made up in September 2015 the Spanish Network of Smart Cities (RECI- Red Española de Ciudades Inteligentes). This research is part of a larger project about Smart Cities’ evaluation (+CITIES), the project evaluates RECI’s cities in all the axes. The analysis was carried out taking into account sociodemographic indicators such as the size of the city or the municipal budget per inhabitant. The mobility’s evaluation in those cities has been focused in: sustainability mobility urban plans and measures to reduce the number of vehicles. The 62 cities from the RECI have been evaluated according to their degree of progress in several Smart Cities’ initiatives related to smart mobility. The applied methodology has been specifically made for this project. The grading scale has different ranks depending on the deployment level of smart cities’ initiatives.Moreno Alonso, C.; Baucells Aletà, N.; Arce Ruiz, RM. (2016). SMART MOBILITY IN SMART CITIES.

Criterios de diferenciación entre potros sépticos y potros inmaduros

Dos de las principales causas del síndrome de debilidad generalizada y falta de reflejo de succión, el cual constituye el principal motivo de ingreso en la clínica neonatológica equina, son la sepsis y la inmadurez. Aunque en muchos casos están asociadas en el mismo paciente, no siempre ocurre, por lo que pensamos que es de gran utilidad establecer los criterios de diferenciación entre potros sépticos e inmaduros, con el objeto de ser capaces de diagnosticarlos correctamente. En el trabajo se definen ambos conceptos: potro séptico como aquel que padece un proceso infeccioso, y potro inmaduro como aquel con una falta de desarrollo. Asimismo, se expone un caso clínico de cada uno de los dos tipos, a modo de ejemplo. Finalmente, se concluyen una serie de puntos básicos a tener en cuenta para comparar y diferenciar ambos casos, tanto a nivel de diagnóstico como de tratamiento. Así, la sintomatología de un potro séptico es la de hiperdinamia o shock, dependiendo de la fase en que se encuentre, mientras que en el potro inmaduro se observaran rasgos característicos, como la laxitud de tendones o la persistencia de las membranas en los cascos, indicativos de falta de desarrollo antes del momento del parto. En lo relativo al tratamiento, se basa, además de en la estabilización básica del paciente, en la antibioterapia en los potros sépticos, y en la utilización de corticoides en los inmaduros, siempre que no sea posible el tratamiento con surfactante artificial, cosa que debido al elevado coste económico no suele ser posible en prácticamente ningún caso.Two of the main causes of the generalized weakness syndrome/lack of suction (main reason of admission in the equine neonatologycal clinic) are sepsis and immaturity. Therefore, we think that is very interesting for the equine vet to differentiate septic from immature foals and to make a correct diagnosis. In our project we define both concepts (septic foal- those with an infection- and immature foal- with a lack of development). To take as an example, two real cases are explained. Finally, we identify several basics points to take into account in order to compare and differentiate both cases, pointing up symptoms (hiperdinamy/shock, depending on the phase, in septic foal; lack of development in the immature), and treatment (based in antibiotherapy in septic foals, and in corticoids in some cases in immature foals, if is not possible to treat with artificial surfactant)

Characterization of Mycobacterium tuberculosis Beijing isolates from the Mediterranean area

<p>Abstract</p> <p>Background</p> <p>The Beijing lineage of <it>Mycobacterium tuberculosis </it>is causing concern due to its global distribution and its involvement in severe outbreaks. Studies focused on this lineage are mainly restricted to geographical settings where its prevalence is high, whereas those in other areas are scarce. In this study, we analyze Beijing isolates in the Mediterranean area, where this lineage is not prevalent and is mainly associated with immigrant cases.</p> <p>Results</p> <p>Only 1% (N = 26) of the isolates from two population-based studies in Spain corresponded to Beijing strains, most of which were pan-susceptible and from Peruvian and Ecuadorian patients. Restriction fragment length polymorphism typing with the insertion sequence IS<it>6110 </it>identified three small clusters (2-3 cases). Mycobacterial interspersed repetitive unit-variable number tandem repeat typing (MIRU-15) offered low discriminatory power, requiring the introduction of five additional loci. A selection of the Beijing isolates identified in the Spanish sample, together with a sample of Beijing strains from Italy, to broaden the analysis context in the Mediterranean area, were assayed in an infection model with THP-1 cells. A wide range of intracellular growth rates was observed with only two isolates showing an increased intracellular replication, in both cases associated with contained production of TNF-α. No correlation was observed between virulence and the Beijing phylogenetic group, clustered/orphan status, or resistance. The Beijing strain responsible for extensive spread on Gran Canaria Island was also identified in Madrid, but did not lead to secondary cases and did not show high infectivity in the infection model.</p> <p>Conclusions</p> <p>The Beijing lineage in our area is a non-homogeneous family, with only certain highly virulent representatives. The specific characterization of Beijing isolates in different settings could help us to accurately identify the virulent representatives before making general assumptions about this lineage.</p

The Use of "EOF" in the Mean Sea Level Oscillations Study An Application to Cadiz

Oscillation modes in mean sea level in the port of Cadiz are computed and analyzed from simultaneous water level and atmospheric pressure records. Empirical Orthogonal Function Decomposition (EOF), cross spectral and least square harmonic analysis are used. EOF is applied in an unusual way in order to extract common oscillation modes of atmospheric pressure and Mean Sea Level (MSL) series. In spite of the short length of time series, less than four months, EOF is a very powerful tool and makes possible the isolation of astronomical and meteorological oscillation modes

An experimental study of fog and cloud computing in CEP-based Real-Time IoT applications

Internet of Things (IoT) has posed new requirements to the underlying processing architecture, specially for real-time applications, such as event-detection services. Complex Event Processing (CEP) engines provide a powerful tool to implement these services. Fog computing has raised as a solution to support IoT real-time applications, in contrast to the Cloud-based approach. This work is aimed at analysing a CEP-based Fog architecture for real-time IoT applications that uses a publish-subscribe protocol. A testbed has been developed with low-cost and local resources to verify the suitability of CEP-engines to low-cost computing resources. To assess performance we have analysed the effectiveness and cost of the proposal in terms of latency and resource usage, respectively. Results show that the fog computing architecture reduces event-detection latencies up to 35%, while the available computing resources are being used more efficiently, when compared to a Cloud deployment. Performance evaluation also identifies the communication between the CEP-engine and the final users as the most time consuming component of latency. Moreover, the latency analysis concludes that the time required by CEP-engine is related to the compute resources, but is nonlinear dependent of the number of things connected

Salmonella enterica serovars Typhimurium and Enteritidis causing mixed infections in febrile children in Mozambique

Background and purpose: Invasive nontyphoidal salmonellosis, mostly caused by serovars Typhimurium and Enteritidis of Salmonella enterica, has emerged as a major public health problem in sub-Saharan Africa. The aim of this study was the clinical and microbiological characterization of nontyphoidal salmonellosis episodes affecting febrile children in Mozambique. Patients and methods: The clinical records of the patients were evaluated, and S. enterica isolates were characterized with regard to serovar, phage type, antimicrobial resistance (phenotype/responsible genes), plasmid content, pulsed-field gel electrophoresis, and multilocus sequence typing. Results: Fifteen S. Typhimurium and 21 S. Enteritidis isolates were recovered from blood samples of 25 children, the majority with underlying risk factors. With regard to phage typing, most isolates were either untypeable or reacted but did not conform, revealing that a number of previously unrecognized patterns are circulating in Mozambique. Most isolates were multidrug-resistant, with nearly all of the responsible genes located on derivatives of serovar-specific virulence plasmids. ST313 and ST11 were the predominant sequence types associated with S. Typhimurium and S. Enteritidis, respectively, and the uncommon ST1479 was also detected in S. Enteritidis. A distinct XbaI fragment of ~350 kb was associated with pulsed-field gel electrophoresis patterns of multidrug-resistant isolates of S. Enteritidis. Nearly half of the children were coinfected with both serovars, a fact expected to aggravate the disease and hamper the treatment. However, particularly poor outcomes were not observed for the coinfected patients. Conclusion: Mixed Salmonella infections could frequently occur in febrile children in Mozambique. Additional studies are required to determine their actual impact and consequences, not only in this country, but also in other African countries
