New records of moths (Insecta, Lepidoptera) from urban gardens on Terceira Island with new data on recently introduced species to the Azores
The urban Duque da Terceira Garden, in the main town of Angra do Heroísmo (Terceira, Azores), was investigated to describe the species composition of moths (Insecta, Lepidoptera). Moths were sampled with two methods: SLAM traps (between April and September 2017) and light trapping (two sessions in the summer of 2017). A total of 42 taxa were sampled with the addition of 19 new records for Duque da Terceira Garden, five of which were also new records for Terceira Island. The five species recorded as new for Terceira were subjected to an exhaustive taxonomic analysis. In addition, we revised the colonization status of some species. Our results show that urban gardens may help the establishment of exotic species and that it is necessary to monitor and control how these species established in urban environments.info:eu-repo/semantics/publishedVersio
Publishing Linked Data - There is no One-Size-Fits-All Formula
Publishing Linked Data is a process that involves several design decisions and technologies. Although some initial guidelines have been already provided by Linked Data publishers, these are still far from covering all the steps that are necessary (from data source selection to publication) or giving enough details about all these steps, technologies, intermediate products, etc. Furthermore, given the variety of data sources from which Linked Data can be generated, we believe that it is possible to have a single and uni�ed method for publishing Linked Data, but we should rely on di�erent techniques, technologies and tools for particular datasets of a given domain. In this paper we present a general method for publishing Linked Data and the application of the method to cover di�erent sources from di�erent domains
Unexpected dielectric response in lead zirconate titanate ceramics: The role of ferroelectric domain wall pinning effects
Temperature dependent dielectric response has been measured in Pb(Zr1-xTix)O-3 ceramics. Samples of different compositions (x=0.40, 0.47, and 0.60), pure and doped with Nb-or Fe, were studied at temperatures between 15 and 700 K and in the frequency range from 100 Hz to 1 MHz. Unexpected dielectric behavior has been found around room temperature. Anomalous temperature dependent permittivity is observed in pure and Fe-doped samples but not in Nb-doped samples. The anomaly appears related to the presence of oxygen vacancies but not on the sample crystallographic phase. The authors suggest that the anomaly may be a manifestation of the domain wall pinning effect. (C) 2007 American Institute of Physics.Peer ReviewedPostprint (published version
Jujuy Province (NW Argentina): STR Markers Unveil Microgeographic Differentiation Over a Steep Mountainous Landscape
This study explores potential signals of microdifferentiation on the gene pool of three high-altitude populations from Jujuy province (NW Argentina) using highly polymorphic markers. These human communities are characterized by extreme living conditions and very low population densities owing to considerable height above sea level and steep orography. A set of autosomal STRs located at chromosome 6 (6p21.3) was typed in samples from Quebrada Baja (~2,500 m), Quebrada Alta (~ 3,300 m), and Puna (\u3e 3,500 m). Genetic diversity was estimated through the observed (Ho) and expected (He) heterozygosities, and the haplotype diversity. Analyses of the molecular variance (AMOVA) and population differentiation tests based on allele and haplotype frequencies were performed to assess genetic heterogeneity among subgroups. No deviation from HWE expectations was detected for each separate subpopulation; yet, significant departures were detected in the analysis considering the whole area (D6S2792 and D6S105 loci). Overall, genetic diversity showed a decreasing trend as the altitude increases. Thus, allele and haplotype frequencies showed the most significant differences between Puna and Quebrada Baja, which are the populations sited at the edges of the altitude range. The trend to the reduction of the heterozygosity with altitude proves to be compatible with historical patterns of colonization, interregional migration trends, population density, and genetic admixture. The main consequence of the complex mountainous landscape of Jujuy would be an imbalance in the interplay gene flow-genetic drift favoring the latter. The combined effect of restricted gene flow with intense genetic drift would have promoted local genetic differentiation between Jujuy highlands\u27 subpopulations, leading to spatial patterning of the allele frequencies not entirely attributable to geographic distance. Our findings corroborate the effectiveness of STRs to identify microevolutionary changes
Relationship between foot eversion and thermographic foot skin temperature after running
[EN] The main instruments to assess foot eversion have some limitations (especially for field applications), and therefore it is necessary to explore new methods. The objective was to determine the relationship between foot eversion and skin temperature asymmetry of the foot sole (difference between medial and lateral side), using infrared thermography. Twenty-two runners performed a running test lasting 30 min. Skin temperature of the feet soles was measured by infrared thermography before and after running. Foot eversion during running was measured by kinematic analysis. Immediately after running, weak negative correlations were observed between thermal symmetry of the rearfoot and eversion at contact time, and between thermal symmetry of the entire plantar surface of the foot and maximum eversion during stance phase (r = −0.3 and p = 0.04 in both cases). Regarding temperature variations, weak correlations were also observed (r = 0.4 and p < 0.05). The weak correlations observed in this study suggest that skin temperature is not related to foot eversion. However, these results open interesting future lines of researchSIDirección General de Investigación Científica y 397 Técnica (DGICT) (DEP2013-48420-P); Ministerio de 398 Educación, Cultura y Deporte (MECD) (Doctoral 399 Fellowship (FPU))
The HERC proteins and the nervous system
The HERC protein family is one of three subfamilies of Homologous to E6AP C-terminus (HECT) E3 ubiquitin ligases. Six HERC genes have been described in humans, two of which encode Large HERC proteins -HERC1 and HERC2- with molecular weights above 520 kDa that are constitutively expressed in the brain. There is a large body of evidence that mutations in these Large HERC genes produce clinical syndromes in which key neurodevelopmental events are altered, resulting in intellectual disability and other neurological disorders like epileptic seizures, dementia and/or signs of autism. In line with these consequences in humans, two mice carrying mutations in the Large HERC genes have been studied quite intensely: the tambaleante mutant for Herc1 and the Herc2+/530 mutant for Herc2. In both these mutant mice there are clear signs that autophagy is dysregulated, eliciting cerebellar Purkinje cell death and impairing motor control. The tambaleante mouse was the first of these mice to appear and is the best studied, in which the Herc1 mutation elicits: (i) delayed neural transmission in the peripheral nervous system; (ii) impaired learning, memory and motor control; and (iii) altered presynaptic membrane dynamics. In this review, we discuss the information currently available on HERC proteins in the nervous system and their biological activity, the dysregulation of which could explain certain neurodevelopmental syndromes and/or neurodegenerative diseases.Ministerio de Economía y Competitividad SAF2015-64171-
Spanish Initiative for the Automation in Urban Transport: AutoMOST
The progressive automation of transport will imply a new paradigm in mobility, which will profoundly affect people, logistics of goods, as well as other sectors dependent on transport. It is precise within this automation where the development of new driving technologies is going to cause a great impact on the mobility of the near future, and that will have an effect on the economic, natural and social environment. It is therefore a primary issue at the global level, as it is reflected in the work programs of the European Commission in relation to the road transport [1] [2]. Thus, the size impact is caused by the following novelties and advantages: 1) Safety: Accidents reduction caused by human error; 2) Efficiency increase in transportation, both in energy consumption and time; 3) Comfort for users and professionals who will increase their operational availability to execute other more valuable tasks, both for them and enterprises; 4) Social Inclusion: enabling mobility easily for everybody during more time; 5) Accessibility, to get to city centers and other difficult reach places. It should be noted that the economic impact projected for automated driving for the years to come ranges up to €71 bn in 2030, when estimated global market for automated vehicles is 44 million vehicles, as is reflected in document Automated Driving Roadmap by ERTRAC [3], European Road Transport Research Advisory Council (http://www.ertrac.org/uploads/documentsearch/id38/ERTRAC_Automated-Driving-2015.pdf). As background that already anticipates these im-provements, the Advance Driver Assistance System (ADAs) have already showed the safety increase in the last ten years, but always maintain a leading role for the driver. Related to the efficiency increase, automated driving offers great opportunities for those companies where mobility is a key factor in operating costs, and affects the whole value chain. The project opportunity is consistent with ERTRAC vision, especially in applications focused on the urban environment [4], where it is expected a deployment of the technology of high level automation in an immediate future. This is possible by the potential to incorporate smart infrastructure to improve guidance and positioning, as well as lower speed, which eases its progressive deployment. The objective of AutoMOST is developing technologies for the automation of vehicles in urban transport and industrial applications, to increase significantly the efficiency, safety and environmental sustainability. More specifically, AutoMOST will allow the implementation of shared control systems (Dual-Mode) [5] for future automated vehicles that allow the services operate more efficiently and flexibly, in a context of intelligent and connected infrastructures.This work is supported by the Centre for the Development of Industrial Technology

Body composition in breast cancer survivors in Sonorenses women
INTRODUCTION: Breast cancer is the most common type of cancer in the worldwide. In the same sense, this disease is one of the most common cancers affecting Mexican women. In the year 2014 in México, there were 11,372 new cases of breast cancer with an incidence rate of 22.56 per 100,000 in habitants older than 10 years. Women with breast cancer are often subjected to an operation due to this affectation which decreases its functionality and body composition. PURPOSE: To examine the body composition in breast cancer survivors in a sample of women from Hermosillo, Sonora, México. METHODS: This study was a cross-sectional descriptive study design. 21 women with breast cancer who had been operated on left arm and had been recruited at one university-based exercise program for breast cancer survivors in Hermosillo, Sonora, México. Body composition (BC) was measured. The right arm non-operated was considered as control. Statistical difference between the operated versus non-operated arm were determined with t-student test for independent samples. RESULTS: In the present study, body fat (1719.1 ± 456.7 vs. 1819.8 ± 467.9 grams, p ≤ 0.05), lean mass (1960.2 ± 308.7 vs. 2151.5 ± 313.5 grams, p ≤ 0.05) and total body mass (3679.3 ± 643.3 vs. 3971.1 ± 675.9 grams, p ≤ 0.05) of the left operated arm of women who breast cancer survivors were significantly lower than the mean of the right non-operated arm. CONCLUSION: Breast cancer survivors’ women who have underwent an operation on their left arm sowed a lower percentage of fat, fat mass and total mass compared to their non-operate arm. The present study underline the importance to apply rehabilitation or exercise program focused to reduce the changes in the body composition
