Knowledge representation tool for cognitiveprocesses modeling

In the last decades, neuropsychological theories tend to consider cognitive functions as a result of the whole brainwork and not as individual local areas of its cortex. Studies based on neuroimaging techniques have increased in the last years, promoting an exponential growth of the body of knowledge about relations between cognitive functions and brain structures [1]. However, so fast evolution make complicated to integrate them in verifiable theories and, even more, translated in to cognitive rehabilitation. The aim of this research work is to develop a cognitive process-modeling tool. The purpose of this system is, in the first term, to represent multidimensional data, from structural and functional connectivity, neuroimaging, data from lesion studies and derived data from clinical intervention [2][3]. This will allow to identify consolidated knowledge, hypothesis, experimental designs, new data from ongoing studies and emerging results from clinical interventions. In the second term, we pursuit to use Artificial Intelligence to assist in decision making allowing to advance towards evidence based and personalized treatments in cognitive rehabilitation. This work presents the knowledge base design of the knowledge representation tool. It is compound of two different taxonomies (structure and function) and a set of tags linking both taxonomies at different levels of structural and functional organization. The remainder of the abstract is organized as follows: Section 2 presents the web application used for gathering necessary information for generating the knowledge base, Section 3 describes knowledge base structure and finally Section 4 expounds reached conclusions.

Rule Representation in Distributed Environments with Accepting Networks of Splicing Processors.

This paper presents the model named Accepting Networks of Evolutionary Processors as NP-problem solver inspired in the biological DNA operations. A processor has a rules set, splicing rules in this model,an object multiset and a filters set. Rules can be applied in parallel since there exists a large number of copies of objects in the multiset. Processors can form a graph in order to solve a given problem. This paper shows the network configuration in order to solve the SAT problem using linear resources and time. A rule representation arquitecture in distributed environments can be easily implemented using these networks of processors, such as decision support systems, as shown in the paper.

Symmetry issues in Directly Irradiated Targets

In direct drive Inertial Confinement Fusion (ICF), the typical laser beam to laser beam angle is around 30o. This fact makes the study of the irradiation symmetry agenuine 3D problem. In this paper we use the three dimensional version of the MULTI hydrocode to assess the symmetry of such ICF implosions. More specifically, we study a shock-ignition proposal for the Laser-M´egajoule facility (LMJ) in which two of the equatorial beam cones are used to implode and pre compress a spherical capsule (the “reference” capsule of HiPER project) made of 0.59 mg of pure Deuterium-Tritium mixture. The symmetry of this scheme is analysed and optimized to get a design inside the operating limits of LMJ. The studied configuration has been found essentially axial-symmetric, so that the use of 2D hydrocodes would be appropriate for this specific situation

Terminological Importation for Adapting Reusable Knowledge Representation Components in the KSM Environment

This paper describes the adaptation approach of reusable knowledge representation components used in the KSM environment for the formulation and operationalisation of structured knowledge models. Reusable knowledge representation components in KSM are called primitives of representation. A primitive of representation provides: (1) a knowledge representation formalism (2) a set of tasks that use this knowledge together with several problem-solving methods to carry out these tasks (3) a knowledge acquisition module that provides different services to acquire and validate this knowledge (4) an abstract terminology about the linguistic categories included in the representation language associated to the primitive. Primitives of representation usually are domain independent. A primitive of representation can be adapted to support knowledge in a given domain by importing concepts from this domain. The paper describes how this activity can be carried out by mean of a terminological importation. Informally, a terminological importation partially populates an abstract terminology with concepts taken from a given domain. The information provided by the importation can be used by the acquisition and validation facilities to constraint the classes of knowledge that can be described using the representation formalism according to the domain knowledge. KSM provides the LINK-S language to specify terminological importation from a domain terminology to an abstract one. These terminologies are described in KSM by mean of the CONCEL language. Terminological importation is used to adapt reusable primitives of representation in order to increase the usability degree of such components in these domains. In addition, two primitives of representation can share a common vocabulary by importing common domain CONCEL terminologies (conceptual vocabularies). It is a necessary condition to make possible the interoperability between different, heterogeneous knowledge representation components in the framework of complex knowledge - based architectures.

Unified representation of monitoring information across federated cloud infrastructures

Nowadays one of the issues hindering the potential of federating cloud-based infrastructures to reach much larger scales is their standard management and monitoring. In particular, this is true in cases where these federated infrastructures provide emerging Future Internet and Smart Cities-oriented services, such as the Internet of Things (IoT), that benefit from cloud services. The contribution of this paper is the introduction of a unified monitoring architecture for federated cloud infrastructures accompanied by the adoption of a uniform representation of measurement data. The presented solution is capable of providing multi-domain compatibility, scalability, as well as the ability to analyze large amounts of monitoring data, collected from datacenters and offered through open and standardized APIs. The solution described herein has been deployed and is currently running on a community of 5 infrastructures within the framework of the European Project XIFI, to be extended to 12 more infrastructures.

SMART Protocols: seMAntic represenTation for experimental protocols

Two important characteristics of science are the ?reproducibility? and ?clarity?. By rigorous practices, scientists explore aspects of the world that they can reproduce under carefully controlled experimental conditions. The clarity, complementing reproducibility, provides unambiguous descriptions of results in a mechanical or mathematical form. Both pillars depend on well-structured and accurate descriptions of scientific practices, which are normally recorded in experimental protocols, scientific workflows, etc. Here we present SMART Protocols (SP), our ontology-based approach for representing experimental protocols and our contribution to clarity and reproducibility. SP delivers an unambiguous description of processes by means of which data is produced; by doing so, we argue, it facilitates reproducibility. Moreover, SP is thought to be part of e-science infrastructures. SP results from the analysis of 175 protocols; from this dataset, we extracted common elements. From our analysis, we identified document, workflow and domain-specific aspects in the representation of experimental protocols. The ontology is available at http://purl.org/net/SMARTprotocol

Study of the effects of moving targets in SAR images for their detection.

Synthetic Aperture Radar’s (SAR) are systems designed in the early 50’s that are capable of obtaining images of the ground using electromagnetic signals. Thus, its activity is not interrupted by adverse meteorological conditions or during the night, as it occurs in optical systems. The name of the system comes from the creation of a synthetic aperture, larger than the real one, by moving the platform that carries the radar (typically a plane or a satellite). It provides the same resolution as a static radar equipped with a larger antenna. As it moves, the radar keeps emitting pulses every 1/PRF seconds —the PRF is the pulse repetition frequency—, whose echoes are stored and processed to obtain the image of the ground. To carry out this process, the algorithm needs to make the assumption that the targets in the illuminated scene are not moving. If that is the case, the algorithm is able to extract a focused image from the signal. However, if the targets are moving, they get unfocused and/or shifted from their position in the final image. There are applications in which it is especially useful to have information about moving targets (military, rescue tasks,studyoftheflowsofwater,surveillanceofmaritimeroutes...).Thisfeatureiscalled Ground Moving Target Indicator (GMTI). That is why the study and the development of techniques capable of detecting these targets and placing them correctly in the scene is convenient. In this document, some of the principal GMTI algorithms used in SAR systems are detailed. A simulator has been created to test the features of each implemented algorithm on a general situation with moving targets. Finally Monte Carlo tests have been performed, allowing us to extract conclusions and statistics of each algorithm.

Onyx: A Linked Data approach to emotion representation

Extracting opinions and emotions from text is becoming increasingly important, especially since the advent of micro-blogging and social networking. Opinion mining is particularly popular and now gathers many public services, datasets and lexical resources. Unfortunately, there are few available lexical and semantic resources for emotion recognition that could foster the development of new emotion aware services and applications. The diversity of theories of emotion and the absence of a common vocabulary are two of the main barriers to the development of such resources. This situation motivated the creation of Onyx, a semantic vocabulary of emotions with a focus on lexical resources and emotion analysis services. It follows a linguistic Linked Data approach, it is aligned with the Provenance Ontology, and it has been integrated with the Lexicon Model for Ontologies (lemon), a popular RDF model for representing lexical entries. This approach also means a new and interesting way to work with different theories of emotion. As part of this work, Onyx has been aligned with EmotionML and WordNet-Affect.

MedVir: an interactive representation system of multidimensional medical data applied to Traumatic Brain Injury's rehabilitation prediction

Clinicians could model the brain injury of a patient through his brain activity. However, how this model is defined and how it changes when the patient is recovering are questions yet unanswered. In this paper, the use of MedVir framework is proposed with the aim of answering these questions. Based on complex data mining techniques, this provides not only the differentiation between TBI patients and control subjects (with a 72% of accuracy using 0.632 Bootstrap validation), but also the ability to detect whether a patient may recover or not, and all of that in a quick and easy way through a visualization technique which allows interaction.

La Ordenación del Territorio en las Ciudades Globales Europeas: El caso de Madrid

En la Comunidad de Madrid el modelo de ocupación del territorio en las dos últimas décadas ha obedecido a factores de oferta del mercado y no a las necesidades de la población, ello provoca un consumo de suelo y de recursos que conducen a una sobrexplotación insostenible. Las metrópolis globales están experimentando rápidas e intensas transformaciones, basadas en los paradigmas emergentes de la globalización, la gobernanza, la metropolizacion y la dispersión de las actividades en el territorio y a través de ellos se abordan los planes de Londres, París y las tentativas de Madrid. La globalización provoca la pérdida de soberanía de las administraciones publicas y la competitividad entre las ciudades globales en Europa, Londres, Paris y Madrid, son centros de poder, de concentración y crecimiento donde se produce la dualización del espacio y donde la desigualdad participa de la restructuración urbana, concentración de pobreza frente a espacios de la nueva clase emergente en donde dominan los sectores de servicios y las tecnologías de la información. Frente al desarrollo urbano neoliberal de regulación a través del mercado y basada en criterios de eficiencia de la Nueva Gestión Pública, se vislumbra la posibilidad de que la sociedad se administre a si misma por medio de acciones voluntarias y responsables que promuevan los intereses colectivos mediante el reconocimiento de su propia identidad, introduciendo el concepto de gobernanza. Frente, a la explotación del territorio por parte de la sociedad extractiva que genera corrupcion, se propone un modelo de cooperación público-privada basado en la confianza mutua, un marco regulador estable, la transparencia y la información a cuyo flujo más homogéneo contribuirán sin duda las TICs. En todo este proceso, las regiones metropolitanas en Europa se erigen como motores del crecimiento, donde los límites administrativos son superados, en un territorio cada vez más extendido y donde los gobiernos locales tienen que organizarse mediante un proceso de cooperación en la provisión de servicios que ayuden a evitar los desequilibrios territoriales. El fenómeno de la dispersión urbana en desarrollos de baja densidad, los centros comerciales periféricos, la expulsión hacia la periferia de las actividades de menor valor añadido y la concentración de funciones directivas en el centro, conducen a una fragmentación del territorio en islas dependientes del automóvil y a procesos de exclusión social por la huida de las rentas altas y la expulsión de las rentas bajas de los centros urbanos. Se crean fragmentos monofuncionales y discontinuos, apoyados en las autovías, lugares carentes de identidad y generadores de despilfarro de recursos y una falta de sostenibilidad ambiental, económica y social. El estudio de la cultura de la planificación en Europa ayuda a comprender los diferentes enfoques en la ordenación del territorio y el proceso de convergencia entre las diferentes regiones. Los documentos de la UE se basan en la necesidad de la competitividad para el crecimiento europeo y la cohesión social y en relación al territorio en los desarrollos policéntricos, la resolución del dualismo campo-ciudad, el acceso equilibrado a las infraestructuras, la gestión prudente de la naturaleza, el patrimonio y el fomento de la identidad. Se proponen dos niveles de estudio uno actual, los últimos planes de Londres y Paris y el otro la evolución de las tentativas de planes en la Región madrileña siempre en relación a los paradigmas emergentes señalados y su reflejo en los documentos. El Plan de Londres es estratégico, con una visión a largo plazo, donde se confiere un gran interés al proceso, al papel del alcalde como líder y su adaptación a las circunstancias cambiantes, sujeto a las incertidumbres de una ciudad global. El desarrollo del mismo se concibe a través de la colaboración y cooperación entre las administraciones y actores. La estructura del documento es flexible, establece orientaciones y guías indicativas, para la redacción de los planes locales, no siendo las mismas vinculantes y con escasa representación grafica. El Plan de París es más un plan físico, similar al de otros centros europeos, trabaja sobre los sectores y sobre los territorios, con información extensa, con características de “Plan Latino” por la fuerza de la expresión gráfica, pero al mismo tiempo contiene una visión estratégica. Es vinculante en sus determinaciones y normativas, se plantea fomentar, pero también prohibir. Ambos planes tratan la competitividad internacional de sus centros urbanos, la igualdad social, la inclusión de todos los grupos sociales y la vivienda como una cuestión de dignidad humana. Londres plantea la gobernanza como cooperación entre sector público-privado y la necesaria cooperación con las regiones limítrofes, en París las relaciones están más institucionalizadas resaltando la colaboración vertical entre administraciones. Ambos plantean la densificación de nodos servidos por transporte público, modos blandos y el uso los TODs y la preservación de la infraestructura verde jerarquizada, la potenciación de la red azul y la mejora del paisaje de las periferias. En las “tentativas” de planes territoriales de Madrid se constata que estuvieron sujetas a los ciclos económicos. El primer Documento las DOT del año 1984, no planteaba crecimiento, ni económico ni demográfico, a medio plazo y por ello no proponía una modificación del modelo radio concéntrico. Se trataba de un Plan rígido volcado en la recuperación del medio rural, de la ciudad, el dimensionamiento de los crecimientos en función de las dotaciones e infraestructuras existentes. Aboga por la intervención de la administración pública y la promoción del pequeño comercio. Destaca el desequilibrio social en función de la renta, la marginación de determinados grupos sociales, el desequilibrio residencia/empleo y la excesiva densidad. Incide en la necesidad de viviendas para los más desfavorecidos mediante el alquiler, la promoción suelo público y la promoción del ferrocarril para dar accesibilidad al espacio central. Aboga por el equipamiento de proximidad y de pequeño tamaño, el tratamiento paisajístico de los límites urbanos de los núcleos y el control de las actividades ilegales señalando orientaciones para el planeamiento urbano. Las Estrategias (1989) contienen una visión: la modificación del modelo territorial, mediante la intervención pública a través de proyectos. Plantea la reestructuración económica del territorio, la reconversión del aparato productivo, la deslocalización de actividades de escaso valor añadido y una mayor ubicuidad de la actividad económica. Incide en la difusión de la centralidad hacia el territorio del sur, equilibrándolo con el norte, tratando de recomponer empleo y residencia, integrando al desarrollo económico las periferias entre sí y con el centro. Las actuaciones de transporte consolidarían las actuaciones, modificando el modelo radio concéntrico facilitando la movilidad mediante la red de cercanías y la intermodalidad. El plan se basaba en el liderazgo del Consejero, no integrando sectores como el medio ambiente, ni estableciendo un documento de seguimiento de las actuaciones que evaluara los efectos de las políticas y su aportación al equilibrio territorial, a través de los proyectos realizados. El Documento Preparatorio de las Bases (1995), es más de un compendio o plan de planes, recoge análisis y propuestas de los documentos anteriores y de planes sectoriales de otros departamentos. Presenta una doble estructura: un plan físico integrador clásico, que abarca los sectores y territorios, y recoge las Estrategias previas añadiendo puntos fuertes, como el malestar urbano y la rehabilitación el centro. Plantea la consecución del equilibrio ambiental mediante el crecimiento de las ciudades existentes, la vertebración territorial basada en la movilidad y en la potenciación de nuevas centralidades, la mejora de la habitabilidad y rehabilitación integral del Centro Urbano de Madrid, y la modernización del tejido productivo existente. No existe una idea-fuerza que aglutine todo el documento, parte del reconocimiento de un modelo existente concentrado y congestivo, un centro urbano dual y dos periferias al este y sur con un declive urbano y obsolescencia productiva y al oeste y norte con una dispersión que amenaza al equilibrio medioambiental. Señala como aspectos relevantes, la creciente polarización y segregación social, la deslocalización industrial, la aparición de las actividades de servicios a las empresas instaladas en las áreas metropolitanas, y la dispersión de las actividades económicas en el territorio por la banalización del uso del automóvil. Se plantea el reto de hacer ciudad de la extensión suburbana y su conexión con el sistema metropolitano, mediante una red de ciudades integrada y complementaria, en búsqueda de un mayor equilibrio y solidaridad territorial. Las Bases del PRET (1997) tenían como propósito iniciar el proceso de concertación en que debe basarse la elaboración del Plan. Parte de la ciudad mediterránea compacta, y diversa, y de la necesidad de que las actividades económicas, los servicios y la residencia estén en proximidad, resolviéndolo mediante una potente red de transporte público que permitiese una accesibilidad integrada al territorio. El flujo de residencia hacia la periferia, con un modelo ajeno de vivienda unifamiliar y la concentración del empleo en el centro producen desequilibrio territorial. Madrid manifiesta siempre apostó por la densificación del espacio central urbanizado, produciendo su congestión, frente al desarrollo de nuevos suelos que permitieran su expansión territorial. Precisa que es necesario preservar los valores de centralidad de Madrid, como generador de riqueza, canalizando toda aquella demanda de centralidad, hacia espacios más periféricos. El problema de la vivienda no lo ve solo como social, sino como económico, debido a la pérdida de empleos que supone su paralización. Observa ya los crecimientos residenciales en el borde de la region por el menor valor del suelo. Plantea como la política de oferta ha dado lugar a un modelo de crecimiento fragmentado, desequilibrado, desestructurado, con fuertes déficits dotacionales y de equipamiento, que inciden en la segregación espacial de las rentas, agravando el proceso de falta de identidad morfológica y de desarraigo de los valores urbanos. El plan señalaba que la presión sobre el territorio creaba su densificación por las limitaciones de espacio, Incidía en limitar el peso de la intervención pública, no planteando propuestas de cooperación público-privado. La mayor incoherencia estriba en que los objetivos eran innovadores y coinciden en su mayoría con las propuestas estudiadas de Londres o Paris, pero se intentan implementar a través de un cambio hacia un modelo reticulado homogéneo, expansivo sobre el territorio, que supone un consumo de suelo y de infraestructuras para solucionar un problema inexistente, la gestión de la densidad. Durante las dos últimas décadas en ausencia de un plan regional, la postura neoliberal fue la de un exclusivo control de legalidad del planeamiento, los municipios entraron en un proceso de competencia para aprovechar las iniciales ventajas económicas de los crecimientos detectados, que proporcionaban una base económica “sólida” a unos municipios con escasos recursos en sus presupuestos municipales. La legislación se modifica a requerimiento de grupos interesados, no existiendo un marco estable. Se pierde la figura del plan no solo a nivel regional, si no en los sectores y el planeamiento municipal donde los municipios tiende a basarse en modificaciones puntuales con la subsiguiente pérdida del modelo urbanístico. La protección ambiental se estructura mediante un extenso nivel de figuras, con diversidad de competencias que impide su efectiva protección y control. Este proceso produce un despilfarro en la ocupación del suelo, apoyada en las infraestructuras viarias, y un crecimiento disperso y de baja densidad, cada vez más periférico, produciéndose una segmentación social por dualización del espacio en función de niveles de renta. Al amparo del boom inmobiliario, se produce una falta de política social de vivienda pública, más basada en la dinamización del mercado con producción de viviendas para rentas medias que en políticas de alquiler para determinados grupos concentrándose estas en los barrios desfavorecidos y en la periferia sur. Se produce un incremento de la vivienda unifamiliar, muchas veces amparada en políticas públicas, la misma se localiza en el oeste principalmente, en espacios de valor como el entorno del Guadarrama o con viviendas más baratas por la popularización de la tipología en la frontera de la Región. El territorio se especializa a modo de islas monofuncionales, las actividades financieras y de servicios avanzados a las empresas se localizan en el norte y oeste próximo, se pierde actividad industrial que se dispersa más al sur, muchas veces fuera de la región. Se incrementan los grandes centros comerciales colgados de las autovías y sin población en su entorno. Todo este proceso ha provocado una pérdida de utilización del transporte público y un aumento significativo del uso del vehículo privado. En la dos últimas décadas se ha producido en la región de Madrid desequilibrio territorial y segmentación social, falta de implicación de la sociedad en el territorio, dispersión del crecimiento y un incremento de los costes ambientales, sociales y económicos, situación, que solo, a través del uso racional del territorio se puede reconducir, apoyado en una planificación integrada sensible y participativa. ABSTRACT In Madrid the model of land occupation in the past two decades has been driven by market supply factors rather than the needs of the population. This results in a consumption of land and resources that leads to unsustainable overexploitation. Addressing this issue must be done through sensitive and participatory integrated planning. Global cities are experiencing rapid and intense change based on the emerging paradigms of globalization, governance, metropolization and the dispersion of activities in the territory. Through this context, a closer look will be taken at the London and Paris plans as well as the tentative plans of Madrid. Globalization causes the loss of state sovereignty and the competitiveness among global cities in Europe; London, Paris and Madrid. These are centres of power, concentration and growth where the duality of space is produced, and where inequality plays a part in urban restructuration. There are concentrated areas of poverty versus areas with a new emerging class where the services sector and information technologies are dominant. The introduction of ICTs contributes to a more homogeneous flow of information leading, us to the concept of governance. Against neoliberal urban development based on free market regulations and efficiency criteria as established by the “New Public Management”, emerge new ways where society administers itself through voluntary and responsible actions to promote collective interests by recognizing their own identity. A new model of public-private partnerships surfaces that is based on mutual trust, transparency, information and a stable regulatory framework in light of territorial exploitation by the “extractive society” that generates corruption. Throughout this process, European metropolitan regions become motors of growth where administrative boundaries are overcome in an ever expanding territory where government is organized through cooperative processes to provide services that protect against regional imbalances. Urban sprawl or low-density development as seen in peripheral shopping centres, the off-shoring of low added-value activities to the periphery, and the concentration of business and top management functions in the centre, leads to a fragmentation of the territory in automobile dependent islands and a process of social exclusion brought on by the disappearance of high incomes. Another effect is the elimination of low income populations from urban centres. In consequence, discontinuous expansions and mono-functional places that lack identity materialize supported by a highway network and high resource consumption. Studying the culture of urban planning in Europe provides better insight into different approaches to spatial planning and the process of convergence between different regions. EU documents are based on the need of competitiveness for European growth and social cohesion. In relation to polycentric development territory they are based on a necessity to solve the dualism between field and city, balanced access to infrastructures, prudent management of nature and solidifying heritage and identity Two levels of study unfold, the first being the current plans of London and Île-de-France and the second being the evolution of tentative plans for the Madrid region as related to emerging paradigms and how this is reflected in documents. The London Plan is strategic with a long-term vision that focuses on operation, the role of the mayor as a pivotal leader, and the adaptability to changing circumstances brought on by the uncertainties of a global city. Its development is conceived through collaboration and cooperation between governments and stakeholders. The document structure is flexible, providing guidance and indicative guidelines on how to draft local plans so they are not binding, and it contains scarce graphic representation. The Plan of Paris takes on a more physical form and is similar to plans of other European centres. It emphasizes sectors and territories, using extensive information, and is more characteristic of a “Latin Plan” as seen in its detailed graphic expression. However, it also contains a strategic vision. Binding in its determinations and policy, it proposes advancement but also prohibition. Both plans address the international competitiveness of urban centres, social equality, inclusion of all social groups and housing as issues of human dignity. London raises governance and cooperation between public and private sector and the need for cooperation with neighbouring regions. In Paris, the relations are more institutionalized highlighting vertical collaboration between administrations. Both propose nodes of densification served by public transportation, soft modes and the use of TOD, the preservation of a hierarchical green infrastructure, and enhancing the landscape in urban peripheries. The tentative territorial plans for the Madrid region provide evidence that they were subject to economic cycles. The first document of master guidelines (1984) does not address either economic or demographic growth in the mid term and therefore does not propose the modification of the radio-concentric model. It is a rigid plan focused on rural and urban recovery and the dimensioning of growth that depends on endowments and infrastructures. It advocates government intervention and promotes small business. The plan emphasizes social imbalance in terms of income, marginalization of certain social groups, the imbalance of residence/employment and excessive density. It stresses the need for social rent housing for the underprivileged, promotes public land, and the supports rail accessibility to the central area. It backs facilities of proximity and small size, enhancing the landscaping of city borders, controlling illegal activities and draws out guidelines for urban planning. The strategies (1989) contain a vision: Changing the territorial model through public intervention by means of projects. They bring to light economic restructuring of territory, the reconversion of the productive apparatus, relocation of low value-added activities, and greater ubiquity of economic activity. They also propose the diffusion of centrality towards southern territories, balancing it with the north in an attempt to reset employment and residence that integrates peripheral economic development both in the periphery and the centre. Transport would consolidate the project, changing the radius-concentric model and facilitating mobility through a commuter and inter-modality network. The plan derives itself from the leadership of the minister and does not integrate sectors such as environment. It also does not incorporate the existence of a written document that monitors performance to evaluate the effects of policies and their contribution to the territorial balance. The Preparatory Document of the Bases, (1995) is more a compendium, or plan of plans, that compiles analysis and proposals from previous documents and sectorial plans from other departments. It has a dual structure: An integrating physical plan covering the sectors and territories that includes the previous strategies while adding some strengths. One such point is the urban discomfort and the rehabilitation of the centre. It also poses the achievement of environmental balance through the growth of existing cities, the territorial linking based on mobility, strengthening new centres, improving the liveability and comprehensive rehabilitation of downtown Madrid, and the modernization of the existing production network. There is no one powerful idea that binds this document. This is due to the recognition of an existing concentrate and congestive model, a dual urban centre, two eastern and southern suburbs suffering from urban decay, and an obsolescent productive north and west whose dispersion threatens the environmental balance. Relevant aspects the document highlights are increasing polarization and social segregation, industrial relocation, the emergence of service activities to centralized companies in metropolitan areas and the dispersion of economic activities in the territory by the trivialization of car use. It proposes making the city from the suburban sprawl and its connection to the metropolitan system through a network of integrated and complementary cities in search of a better balance and territorial solidarity. The Bases of PRET (1997) aims to start the consultation process that must underpin the development of the plan. It stems from a compact and diverse Mediterranean city along with the need for economic activities, services and residences that are close. To resolve the issue, it presents a powerful network of public transport that allows integrated accessibility to the territory. The flow of residence to the periphery based on a foreign model of detached housing and an employment concentration in the centre produces territorial imbalance. Madrid always opted for the densification of the central space, producing its congestion, against the development of new land that would allow its territorial expansion. The document states that the necessity to preserve the values of the housing problem is not only viewed as social, but also economic due to the loss of jobs resulting from their paralysis. It notes the residential growth in the regional border due to the low price of land and argues that the policy of supply has led to a fragmented model of growth that is unbalanced, unstructured, with strong infrastructure and facility deficits that affect the spatial segregation of income and aggravate the lack of morphological identity, uprooting urban values. The pressure on the territory caused its densification due to space limitation; the proposed grid model causes land consumption and infrastructure to solve a non-problem, density. Focusing on limiting the weight of public intervention, it does not raise proposals for public-private cooperation. The biggest discrepancy is that the targets were innovative and mostly align with the proposals in London and Paris. However, it proposes to be implemented through a shift towards a uniform gridded model that is expansive over territory. During the last two decades, due to the absence of a regional plan, a neoliberal stance held exclusive control of the legality of urban planning. The municipalities entered a competition process to take advantage of initial economic benefits of such growth. This provided a “solid” economic base for some municipalities with limited resources in their municipal budgets. The law was amended without a legal stable framework at the request of stakeholders. The character of the plan is lost not only regionally, but also in the sectors and municipal planning. This tends to be based on specific changes with the loss of an urban model. Environmental protection is organized through an extensive number of protection figures with diverse competencies that prevent its effective protection. This process squanders the use of the land, backed by increasing road infrastructure, dispersed occupations with low-density growth causing a social segmentation due to space duality based on income levels. During the housing boom, there is a reduction in social public housing policy mostly due to a boost in the market of housing production for average incomes than in rental policies for needy social groups that focus on disadvantaged neighbourhoods and southern suburbs. As a result, there is an increase in single-family housing, often protected by public policy. This is located primarily in the west in areas of high environmental value such as Guadarrama. There is also cheaper housing due to the popularization of typology in the border region. There, territory works as a mono-functional islands. Financial activities and advanced services for companies are located to the north and west where industrial activity is lost as it migrates south, often outside the region. The number of large shopping centres hanging off the highway infrastructure with little to no surrounding population increases. This process leads to the loss of dependency on public transport and a significant increase in the use of private vehicles. The absence of regional planning has produced more imbalance, more social segmentation, more dispersed growth and a lot of environmental, social and economic costs that can only be redirected through rational territorial.

Neural systems underlying learning and representation of global motion

We demonstrate performance-related changes in cortical and cerebellar activity. The largest learning-dependent changes were observed in the anterior lateral cerebellum, where the extent and intensity of activation correlated inversely with psychophysical performance. After learning had occurred (a few minutes), the cerebellar activation almost disappeared; however, it was restored when the subjects were presented with a novel, untrained direction of motion for which psychophysical performance also reverted to chance level. Similar reductions in the extent and intensity of brain activations in relation to learning occurred in the superior colliculus, anterior cingulate, and parts of the extrastriate cortex. The motion direction-sensitive middle temporal visual complex was a notable exception, where there was an expansion of the cortical territory activated by the trained stimulus. Together, these results indicate that the learning and representation of visual motion discrimination are mediated by different, but probably interacting, neuronal subsystems.

Orderly cortical representation of vowels based on formant interaction

Psychophysical experiments have shown that the discrimination of human vowels chiefly relies on the frequency relationship of the first two peaks F1 and F2 of the vowel’s spectral envelope. It has not been possible, however, to relate the two-dimensional (F1,F2)-relationship to the known organization of frequency representation in auditory cortex. We demonstrate that certain spectral integration properties of neurons are topographically organized in primary auditory cortex in such a way that a transformed (F1,F2) relationship sufficient for vowel discrimination is realized.

Representation of sound localization cues in the auditory thalamus of the barn owl

Barn owls can localize a sound source using either the map of auditory space contained in the optic tectum or the auditory forebrain. The auditory thalamus, nucleus ovoidalis (N.Ov), is situated between these two auditory areas, and its inactivation precludes the use of the auditory forebrain for sound localization. We examined the sources of inputs to the N.Ov as well as their patterns of termination within the nucleus. We also examined the response of single neurons within the N.Ov to tonal stimuli and sound localization cues. Afferents to the N.Ov originated with a diffuse population of neurons located bilaterally within the lateral shell, core, and medial shell subdivisions of the central nucleus of the inferior colliculus. Additional afferent input originated from the ipsilateral ventral nucleus of the lateral lemniscus. No afferent input was provided to the N.Ov from the external nucleus of the inferior colliculus or the optic tectum. The N.Ov was tonotopically organized with high frequencies represented dorsally and low frequencies ventrally. Although neurons in the N.Ov responded to localization cues, there was no apparent topographic mapping of these cues within the nucleus, in contrast to the tectal pathway. However, nearly all possible types of binaural response to sound localization cues were represented. These findings suggest that in the thalamo-telencephalic auditory pathway, sound localization is subserved by a nontopographic representation of auditory space.
