Intelligent and automatic systems are making our daily life easier. They are able to automate tasks that, up to now, were performed by humans, freeing them from these tedious tasks. They are mainly based on the classical robotic architectures where the stages of perception—using different sensor sources or even a fusion of a set of them—and planning—where intelligent control systems are applied—play a key role. Among all of the fields in which intelligent systems can be applied, transport systems are considered one of the most promising ones since over one million fatalities—including drivers, pedestrians, cyclists and motorcyclists—are registered each year worldwide and they can definitively help to reduce these figures.

Tri-axial accelerometry shows differences in energy expenditure and parental effort throughout the breeding season in long-lived raptors
Cutting-edge technologies are extremely useful to develop new workflows in studying ecological data, particularly to understand animal behavior and movement trajectories at the individual level. Although parental care is a well-studied phenomenon, most studies have been focused on direct observational or video recording data, as well as experimental manipulation. Therefore, what happens out of our sight still remains unknown. Using high-frequency GPS/GSM dataloggers and tri-axial accelerometers we monitored 25 Bonelli’s eagles Aquila fasciata during the breeding season to understand parental activities from a broader perspective. We used recursive data, measured as number of visits and residence time, to reveal nest attendance patterns of biparental care with role specialization between sexes. Accelerometry data interpreted as the overall dynamic body acceleration, a proxy of energy expenditure, showed strong differences in parental effort throughout the breeding season and between sexes. Thereby, males increased substantially their energetic requirements, due to the increased workload, while females spent most of the time on the nest. Furthermore, during critical phases of the breeding season, a low percentage of suitable hunting spots in eagles’ territories led them to increase their ranging behavior in order to find food, with important consequences in energy consumption and mortality risk. Our results highlight the crucial role of males in raptor species exhibiting biparental care. Finally, we exemplify how biologging technologies are an adequate and objective method to study parental care in raptors as well as to get deeper insight into breeding ecology of birds in general.This work was supported by Red Eléctrica de España, Iberdrola Foundation, and Wildlife Service of the Valencian Community Regional Government (Conselleria d’Agricultura, Desenvolupament Rural, Emergència Climàtica i Transició Ecològica, Generalitat Valenciana, Spain).

Parálisis idiopática del nervio hipogloso. Descripción de un caso.
Introduction: Hypoglossal nerve palsy is a rare mononeuropathy. The most common etiologies are tumor, traumatic, cerebral ischemic and iatrogenic causes. Description: We present a man with idiopathic hypoglossal nerve neuropathy. The patient's age, the presence of vascular risk factors and cerebral microangiopathy, and the clinical evolution leads us to discussion about the possibility of a ischemic or diabetic mononeuropathy as the etiology of the deficit. Discussion: In previous published series of idiopathic hypoglossal nerve palsy, the age of presentation is between 20 and 45 years and the patients have a favorable evolution. The pathophysiological mechanism could be similar to Bell's palsy. In our patient the physical examination and the complementary studies were normal, diagnose the deficit as idiopathic hypoglossal nerve palsy. However, due to patient's age, the presence of multiple vascular risk factors, cerebral microangiopathy and the persistence of the symptoms, we consider the existence of a local ischemic or diabetic damage as the cause of the mononeuropathy presented, and we think that the physiopathological mechanism could be similar to other mononeuropathies, such as III or VI cranial nerve palsy. Conclusion: We present an idiopathic hypoglossal nerve palsy, but due to characteristics of our patient, we discuss an ischemic or diabetic cause of the deficit.Introducción: La parálisis del nervio hipogloso es una mononeuropatía poco fre-cuente. Las etiologías más habituales son la tumoral, la traumática, la isquémica cere-bral y la iatrogénica, Descripción: Presentamos el caso de un paciente con neuropa-tía idiopática del nervio hipogloso, en el que por edad, la presencia de factores de riesgo vascular, la microangiopaía cerebral y la evolución nos lleva a discutir acerca de la posibilidad de que se trate de una mononeuropatía isquémica o diabética como etiología del déficit. Discusión: En estudios publicados de parálisis idiopáticas del nervio hipogloso la edad de presentación se sitúa entre los 20 y 45 años y tienen una evolución y recuperación favorable, atribuyéndole un mecanismo fisiopatológico similar al de la paralisis de Bell. En nuestro caso la exploración física y las pruebas complementarias realizadas no mostraron etiología del déficit, encontrándonos ante un nuevo caso de parálisis idiopática del nervio hipogloso. Sin embargo por la edad del paciente, la presencia de múltiples factores de riesgo vascular, la microangiopía cerebral y la persistencia de la sintomatología nos hace plantear la existencia de un mecanismo local, isquémico o diabético, como causa de la mononeuropatía presen-tada y pensar que nos podemos encontrar ante un mecanismo fisiopatológico similar al producido en otras mononeuropatías, como la del III o VI par craneal. Conclusión: Presentamos una parálisis del nervio hipogloso idiopática, que por las característi-cas de nuestro paciente nos hace pensar y discuti una posible etiología isquémica o diabética del déficit
Root high-affinity K+ and Cs+ uptake and plant fertility in tomato plants are dependent on the activity of the high-affinity K+ transporter SlHAK5
Root K+ acquisition is a key process for plant growth and development, extensively studied in the model plant Arabidopsis thaliana. Because important differences may exist among species, translational research supported by specific studies is needed in crops such as tomato. Here we present a reverse genetics study to demonstrate the role of the SlHAK5 K+ transporter in tomato K+ nutrition, Cs+ accumulation and its fertility. slhak5 KO lines, generated by CRISPR-Cas edition, were characterized in growth experiments, Rb+ and Cs+ uptake tests and root cells K+-induced plasma membrane depolarizations. Pollen viability and its K+ accumulation capacity were estimated by using the K+-sensitive dye Ion Potassium Green 4. SlHAK5 is the major system for high-affinity root K+ uptake required for plant growth at low K+, even in the presence of salinity. It also constitutes a pathway for Cs+ entry in tomato plants with a strong impact on fruit Cs+ accumulation. SlHAK5 also contributes to pollen K+ uptake and viability and its absence produces almost seedless fruits. Knowledge gained into SlHAK5 can serve as a model for other crops with fleshy fruits and it can help to generate tools to develop low Cs+ or seedless fruits crops.Fil: Nieves Cordones, Manuel.

Metodología de definición de la línea de Término Municipal mediante técnicas GPS
Actualmente, la práctica del deslinde de términos municipales no está demasiado
extendida en nuestro territorio, pero supone una nueva ventana profesional para el
Ingeniero Técnico en Topografía. La desaparición de multitud de mojones de término
y las continuas disputas entre municipios, por la delimitación de su territorio, lleva a
la urgente necesidad de la revisión de los antiguos deslindes realizados, hace ya
más de un siglo, por el Instituto Geográfico.
En este artículo se realiza una propuesta sobre cada uno de los pasos que se
deben de seguir, desde el punto de vista técnico, para poder llevar a cabo el
deslinde administrativo entre términos municipales; tomando la iniciativa desde uno
de ellos, para posteriormente, plantearlo a los municipios colindantes; en este caso,
como ejemplo práctico de la metodología a seguir, se desarrolla el deslinde del
término municipal de Moncada, en la provincia de Valencia. Se explica la
documentación previa a utilizar y donde conseguirla, así como la metodología e
instrumental utilizado; y por último los documentos finales que permitan plasmar los
resultados obtenidos (reseñas y plano/s).Cazallas Delfa, C.; Rivera Lacomba, M.; Femenia Ribera, C.; Rodrigo Pascual, V. (2010).

Green spaces and cognitive development in primary schoolchildren
© 2015, National Academy of Sciences. All rights reserved. Exposure to green space has been associated with better physical and mental health. Although this exposure could also influence cognitive development in children, available epidemiological evidence on such an impact is scarce. This study aimed to assess the association between exposure to green space and measures of cognitive development in primary schoolchildren. This study was based on 2,593 schoolchildren in the second to fourth grades (7-10 y) of 36 primary schools in Barcelona, Spain (2012-2013). Cognitive development was assessed as 12-mo change in developmental trajectory of working memory, superior working memory, and inattentiveness by using four repeated (every 3 mo) computerized cognitive tests for each outcome. We assessed exposure to green space by characterizing outdoor surrounding greenness at home and school and during commuting by using high-resolution (5 m x5 m) satellite data on greenness (normalized difference vegetation index). Multilevel modeling was used to estimate the associations between green spaces and cognitive development. We observed an enhanced 12-mo progress in working memory and superior working memory and a greater 12-mo reduction in inattentiveness associated with greenness within and surrounding school boundaries and with total surrounding greenness index (including greenness surrounding home, commuting route, and school). Adding a traffic-related air pollutant (elemental carbon) to models explained 20-65% of our estimated associations between school greenness and 12-mo cognitive development. Our study showed a beneficial association between exposure to green space and cognitive development among schoolchildren that was partly mediated by reduction in exposure to air pollution
