Integration of quantum key distribution in metropolitan area networks

The deployment of Quantum Key Distribution forces the development of QKD-links to be operated in current and next-generation photonic metro-access networks. These highly heterogeneous architectures determine the conditions QKD-links need to be optimized for.

A supervised cooperative learning system for early detection of language disorders

The Quality of Life of a person may depend on early attention to his neurodevel-opment disorders in childhood. Identification of language disorders under the age of six years old can speed up required diagnosis and/or treatment processes. This paper details the enhancement of a Clinical Decision Support System (CDSS) aimed to assist pediatricians and language therapists at early identification and re-ferral of language disorders. The system helps to fine tune the Knowledge Base of Language Delays (KBLD) that was already developed and validated in clinical routine with 146 children. Medical experts supported the construction of Gades CDSS by getting scientific consensus from literature and fifteen years of regis-tered use cases of children with language disorders. The current research focuses on an innovative cooperative model that allows the evolution of the KBLD of Gades through the supervised evaluation of the CDSS learnings with experts¿ feedback. The deployment of the resulting system is being assessed under a mul-tidisciplinary team of seven experts from the fields of speech therapist, neonatol-ogy, pediatrics, and neurology.

Integration of multisensor hybrid reasoners to support personal autonomy in the smart home.

The deployment of the Ambient Intelligence (AmI) paradigm requires designing and integrating user-centered smart environments to assist people in their daily life activities. This research paper details an integration and validation of multiple heterogeneous sensors with hybrid reasoners that support decision making in order to monitor personal and environmental data at a smart home in a private way. The results innovate on knowledge-based platforms, distributed sensors, connected objects, accessibility and authentication methods to promote independent living for elderly people. TALISMAN+, the AmI framework deployed, integrates four subsystems in the smart home: (i) a mobile biomedical telemonitoring platform to provide elderly patients with continuous disease management; (ii) an integration middleware that allows context capture from heterogeneous sensors to program environment¿s reaction; (iii) a vision system for intelligent monitoring of daily activities in the home; and (iv) an ontologies-based integrated reasoning platform to trigger local actions and manage private information in the smart home. The framework was integrated in two real running environments, the UPM Accessible Digital Home and MetalTIC house, and successfully validated by five experts in home care, elderly people and personal autonomy.

Analysis of the suitability of existing medical ontologies for building a scalable semantic interoperability solution supporting multi-site collaboration in oncology

Semantic interoperability is essential to facilitate efficient collaboration in heterogeneous multi-site healthcare environments. The deployment of a semantic interoperability solution has the potential to enable a wide range of informatics supported applications in clinical care and research both within as ingle healthcare organization and in a network of organizations. At the same time, building and deploying a semantic interoperability solution may require significant effort to carryout data transformation and to harmonize the semantics of the information in the different systems. Our approach to semantic interoperability leverages existing healthcare standards and ontologies, focusing first on specific clinical domains and key applications, and gradually expanding the solution when needed. An important objective of this work is to create a semantic link between clinical research and care environments to enable applications such as streamlining the execution of multi-centric clinical trials, including the identification of eligible patients for the trials. This paper presents an analysis of the suitability of several widely-used medical ontologies in the clinical domain: SNOMED-CT, LOINC, MedDRA, to capture the semantics of the clinical trial eligibility criteria, of the clinical trial data (e.g., Clinical Report Forms), and of the corresponding patient record data that would enable the automatic identification of eligible patients. Next to the coverage provided by the ontologies we evaluate and compare the sizes of the sets of relevant concepts and their relative frequency to estimate the cost of data transformation, of building the necessary semantic mappings, and of extending the solution to new domains. This analysis shows that our approach is both feasible and scalable.

Reducing the impact of EV charging on the electric grid

One of the main objectives of European Commission related to climate and energy is the well-known 20-20-20 targets to be achieved in 2020: Europe has to reduce greenhouse gas emissions of at least 20% below 1990 levels, 20% of EU energy consumption has to come from renewable resources and, finally, a 20% reduction in primary energy use compared with projected levels, has to be achieved by improving energy efficiency. In order to reach these objectives, it is necessary to reduce the overall emissions, mainly in transport (reducing CO2, NOx and other pollutants), and to increase the penetration of the intermittent renewable energy. A high deployment of battery electric (BEVs) and plug-in hybrid electric vehicles (PHEVs), with a low-cost source of energy storage, could help to achieve both targets. Hybrid electric vehicles (HEVs) use a combination of a conventional internal combustion engine (ICE) with one (or more) electric motor. There are different grades of hybridation from micro-hybrids with start-stop capability, mild hybrids (with kinetic energy recovery), medium hybrids (mild hybrids plus energy assist) and full hybrids (medium hybrids plus electric launch capability). These last types of vehicles use a typical battery capacity around 1-2 kWh. Plug in hybrid electric vehicles (PHEVs) use larger battery capacities to achieve limited electric-only driving range. These vehicles are charged by on-board electricity generation or either plugging into electric outlets. Typical battery capacity is around 10 kWh. Battery Electric Vehicles (BEVs) are only driven by electric power and their typical battery capacity is around 15-20 kWh. One type of PHEV, the Extended Range Electric Vehicle (EREV), operates as a BEV until its plug-in battery capacity is depleted; at which point its gasoline engine powers an electric generator to extend the vehicle's range. The charging of PHEVs (including EREVs) and BEVs will have different impacts to the electric grid, depending on the number of vehicles and the start time for charging. Initially, the lecture will start analyzing the electrical power requirements for charging PHEVs-BEVs in Flanders region (Belgium) under different charging scenarios. Secondly and based on an activity-based microsimulation mobility model, an efficient method to reduce this impact will be presented.

Human resources policies for strategic csr. The experience of ree (Red Eléctrica de España)

Corporate Social Responsibility (CSR) strategies have a strong link with human resources policies. Not only because employees are one of the main stakeholders and because leaders’ style is directly related to the deployment of the strategy, but also, and with a growing importance, because a company culture aligned with CSR values could be a key competitive factor. The relationships among CSR values, employees’ commitment and productivity is one of the research lines of the GIOS (Grupo de Investigación de Organizaciones Sostenibles, Sustainable Organizations Research Group). Employees’ commitment management is one of the main challenges managers face, particularly in companies with a high proportion of knowledge workers. Many pieces of research indicate the direct relationship between employees’ commitment and company success. In this paper the results of a case study in REE (Red Eléctrica de España) identify some key variables to demonstrate that relationship. Based on commitment construct with the duality of emotional and rational commitment, and on the REE employee satisfaction survey, a direct relationship with organizational citizenship behaviour (OCB) variables appears. These OCB variables are an intermediate step with CSR values.From the results analysis of this survey a direct linear relationship can be seen between commitment and organizational citizenship behaviours. The relationships among emotional and rational commitment and OCB are examined separately with the conclusion being reached that there is a strong correlation in both cases. Moreover, the correlation between emotional commitment and OCB is somewhat stronger than that existing between rational commitment and OCB. it can also be seen how emotional commitment increases more strongly than rational commitment as organizational citizenship behaviours are gradually incorporated.

Why neutron guides may end up breaking down? Some results on the macroscopic behaviour of alkali-borosilicate glass support plates under neutron irradiation

In this paper we report on a first part of a study on the mechanisms leading to brittle fracture in neutron guides made of glass as structural element. Such devices are widely used to deliver thermal and cold neu tron beams to experimental lines in most large neutron research facilities. We present results on macroscopic properties of samples of guide glass substrates which are subjected to neutron irradiation at relatively large fluences. The results show a striking dependence of some of the macroscopic properties such as density, shape or surface curvature upon the specific chemical composition of a given glass. The relevance of the present findings for the installation of either replacement guides at the existing facilities or for the deployment of instruments for ongoing projects such as the European Spallation Source is briefly discussed.

Design of a new neutron delivery system for high flux source

La construcción en la actualidad de nuevas fuentes para el uso de haces de neutrones así como los programas de renovación en curso en algunas de las instalaciones experimentales existentes han evidenciado la necesidad urgente de desarrollar la tecnología empleada para la construcción de guías de neutrones con objeto de hacerlas mas eficientes y duraderas. Esto viene motivado por el hecho de que varias instalaciones de experimentación con haces de neutrones han reportado un número de incidentes mecánicos con tales guías, lo que hace urgente el progresar en nuestro conocimiento de los susbtratos vítreos sobre los cuales se depositan los espejos que permiten la reflexión total de los neutrones y como aquellos se degradan con la radiación. La presente tesis se inscribe en un acuerdo de colaboración establecido entre el Institut Max von Laue - Paul Langevin (ILL) de Grenoble y el Consorcio ESS-Bilbao con objeto de mejorar el rendimiento y sostenibilidad de los sistemas futuros de guiado de neutrones. El caso de la Fuente Europea de Espalación en construcción en Lund sirve como ejemplo ya que se contempla la instalación de guías de neutrones de más de 100 metros en algunos de los instrumentos. Por otro lado, instalaciones como el ILL prevén también dentro del programa Endurance de rejuvenecimiento la reconstrucción de varias líneas de transporte de haz. Para el presente estudio se seleccionaron cuatro tipos de vidrios borosilicatados que fueron el Borofloat, N-ZK7, N-BK7 y SBSL7. Los tres primeros son bien conocidos por los especialistas en instrumentación neutrónica ya que se han empleado en la construcción de varias instalaciones mientras que el último es un candidato potencial en la fabricación de substratos para espejos neutrónicos en un futuro. Los cuatro vidrios tiene un contenido en óxido de Boro muy similar, approximadamente un 10 mol.%. Tal hecho que obedece a las regulaciones para la fabricación de estos dispositivos hace que tales substratos operen como protección radiológica absorbiendo los neutrones transmitidos a través del espejo de neutrones. Como contrapartida a tal beneficio, la reacción de captura 10B(n,_)7Li puede degradar el substrato vítreo debido a los 2.5 MeV de energía cinética depositados por la partícula _ y los núcleos en retroceso y de hecho la fragilidad de tales vidrios bajo radiación ha sido atribuida desde hace ya tiempo a los efectos de esta reacción. La metodología empleada en esta tesis se ha centrado en el estudio de la estructura de estos vidrios borosilicatados y como esta se comporta bajo condiciones de radiación. Los materiales en cuestión presentan estructuras que dependen de su composición química y en particular del ratio entre formadores y modificadores de la red iono-covalente. Para ello se han empleado un conjunto de técnicas de caracterización tanto macro- como microscópicas tales como estudios de dureza, TEM, Raman, SANS etc. que se han empleado también para determinar el comportamiento de estos materiales bajo radiación. En particular, algunas propiedades macroscópicas relacionadas con la resistencia de estos vidrios como elementos estructurales de las guías de neutrones han sido estudiadas así como también los cambios en la estructura vítrea consecuencia de la radiación. Para este propósito se ha diseñado y fabricado por el ILL un aparato para irradiación de muestras con neutrones térmicos en el reactor del ILL que permite controlar la temperatura alcanzada por la muestra a menos de 100 °C. Tal equipo en comparación con otros ya existences permite en cuestión de dias acumular las dosis recibidas por una guía en operación a lo largo de varios años. El uso conjunto de varias técnicas de caracterización ha llevado a revelar que los vidrios aqui estudiados son significativamente diferentes en cuanto a su estructura y que tales diferencias afectan a sus propiedades macroscópicas asi como a su comportamiento bajo radiación. Tal resultado ha sido sorprendente ya que, como se ha mencionado antes, algunos de estos vidrios eran bien conocidos por los fabricantes de guías de neutrones y hasta el momento eran considerados prácticamente similares debido a su contenido comparable en óxido de Boro. Sin embargo, los materiales N-BK7 and S-BSL7 muetran gran homogeneidad a todas las escalas de longitud, y más específicamente, a escalas nanométricas las subredes de Sílice y óxido de Boro se mezclan dando logar a estructuras locales que recuerdan a la del cristal de Reedmergnerita. Por el contrario, N-ZK7 y Borofloat muestran dominios separados ricos en Sílice o Boro. Como era de esperar, las importantes diferencias arriba mencionadas se traducen en comportamientos dispares de estos materiales bajo un haz de neutrones térmicos. Los resultados muestran que el N-BK7 y el S-BSL7 son los más estables bajo radiación, lo que macroscópicamente hace que estos materiales muestren un comportamiento similar expandiéndose lentamente en función de la dosis recibida. Por el contario, los otros dos materiales muestran un comportamiento mucho más reactivo, que hace que inicialmente se compacten con la dosis recibida lo que hace que las redes de Silicio y Boro se mezclen resultando en un incremento en densidad hasta alcanzar un valor límite, seguido por un proceso de expansión lenta que resulta comparable al observado para N-BK7 y SBSL7. Estos resultados nos han permitido explicar el origen de las notorias diferencias observadas en cuanto a las dosis límite a partir de las cuales estos materiales desarrollan procesos de fragmentación en superficie. ABSTRACT The building of new experimental neutron beam facilities as well as the renewal programmes under development at some of the already existing installations have pinpointed the urgent need to develop the neutron guide technology in order to make such neutron transport devices more efficient and durable. In fact, a number of mechanical failures of neutron guides have been reported by several research centres. It is therefore important to understand the behaviour of the glass substrates on top of which the neutron optics mirrors are deposited and how these materials degrade under radiation conditions. The case of the European Spallation Source (ESS) at present under construction at Lund is a good example. It previews the deployment of neutron guides having more than 100 metres of length for most of the instruments. Also, the future renovation programme of the ILL, called Endurance, foresees the refurbishment of several beam lines. This Ph.D. thesis was the result of a collaboration agreement between the ILL and ESS-Bilbao aiming to improve the performance and sustainability of future neutron delivery systems. Four different industrially produced alkali-borosilicate glasses were selected for this study: Borofloat, N-ZK7, N-BK7 and SBSL7. The first three are well known within the neutron instrumentation community as they have already been used in several installations whereas the last one is at present considered as a candidate for making future mirror substrates. All four glasses have a comparable content of boron oxide of about 10 mol.%. The presence of such a strong neutron absorption element is in fact a mandatory component for the manufacturing of neutron guides because it provides a radiological shielding for the environment. This benefit is however somewhat counterbalanced since the resulting 10B(n,_)7Li reactions degrade the glass due to the deposited energy of 2.5 MeV by the _ particle and the recoil nuclei. In fact, the brittleness of some of these materials has been ascribed to this reaction. The methodology employed by this study consisted in understanding the general structure of borosilicates and how they behave under irradiation. Such materials have a microscopic structure strongly dependent upon their chemical content and particularly on the ratios between network formers and modifiers. The materials have been characterized by a suite of macroscopic and structural techniques such as hardness, TEM, Raman, SANS, etc. and their behaviour under irradiation was analysed. Some macroscopic properties related to their resistance when used as guide structural elements were monitored. Also, changes in the vitreous structure due to radiation were observed by means of several experimental tools. For such a purpose, an irradiation apparatus has been designed and manufactured to enable irradiation with thermal neutrons within the ILL reactor while keeping the samples below 100 °C. The main advantage of this equipment if compared to others previously available was that it allowed to reach in just some days an equivalent neutron dose to that accumulated by guides after several years of use. The concurrent use of complementary characterization techniques lead to the discovery that the studied glasses were deeply different in terms of their glass network. This had a strong impact on their macroscopic properties and their behaviour under irradiation. This result was a surprise since, as stated above, some of these materials were well known by the neutron guide manufacturers, and were considered to be almost equivalent because of their similar boron oxide content. The N-BK7 and S-BSL7 materials appear to be fairly homogeneous glasses at different length scales. More specifically, at nanometre scales, silicon and boron oxide units seem to mix and generate larger structures somewhat resembling crystalline Reedmergnerite. In contrast, N-ZK7 and Borofloat are characterized by either silicon or boron rich domains. As one could expect, these drastic differences lead to their behaviour under thermal neutron flux. The results show that N-BK7 and S-BSL7 are structurally the most stable under radiation. Macroscopically, such stability results in the fact that these two materials show very slow swelling as a function or radiation dose. In contrast, the two other glasses are much more reactive. The whole glass structure compacts upon radiation. Specifically, the silica network, and the boron units tend to blend leading to an increase in density up to some saturation, followed by a very slow expansion which comes to be of the same order than that shown by N-BK7 and S-BSL7. Such findings allowed us to explain the drastic differences in the radiation limits for macroscopic surface splintering for these materials when they are used in neutron guides.

Outraged spatialities: the production of public scale in the #spanishrevolution

The spatial processes deployed by the 15-M movement in Spain include elements of social change that exceed the limits of conventional politics. Located at a liminal level, these processes operate in the often unnoticed realm of the micro-politics of urban everyday life and the regimes of place that regulate it, providing new criteria for understanding sociospatial and urban phenomena. This article shows how public space, its representations and the spatialities associated with them have served as a support for, have determined and, ultimately, have been reshaped and transformed by the Spanish “indignados” (outraged), in particular in the city and the metropolitan area of Madrid. Drawing on a series of theoretical approaches to the articulation of recent revolts, the deployment of a prefigurative politics and the occupation of public space, I will give an experience-based account of the spatial constitution and effects of these connections in and around Madrid’s Puerta del Sol. As a whole, the indignados’ occupations and actions provide urban theory with conceptual and practical tools to imagine alternative forms of collective commitment in the production of spaces of hope for social progress and generalized self-management.

Function of the oxidative burst in hypersensitive disease resistance.

Microbial elicitors or attempted infection with an avirulent pathogen strain causes the rapid production of reactive oxygen intermediates. Recent findings indicate that H2O2 from this oxidative burst plays a central role in the orchestration of the hypersensitive response: (i) as the substrate driving the cross-linking of cell wall structural proteins to slow microbial ingress prior to the deployment of transcription-dependent defenses and to trap pathogens in cells destined to undergo hypersensitive cell death, (ii) as a local threshold trigger of this programmed death in challenged cells, and (iii) as a diffusible signal for the induction in adjacent cells of genes encoding cellular protectants such as glutathione S-transferase and glutathione peroxidase. These findings provide the basis for an integrated model for the orchestration of the localized hypersensitive resistance response to attack by an avirulent pathogen.

The Future Direction of Delaware Law (Including a Brief Exegesis on Fee Shifting Bylaws)

Delaware sets the governance standards for most public companies. The ability to attract corporations could not be explained solely by the existence of a favorable statutory regime. Delaware was not invariably the first or the only state to implement management friendly provisions. Given the interpretive gaps in the statute and the critical importance of the common law in the governance process, courts played an outsized role in setting legal standards. The management friendly nature of the Delaware courts contributed significantly to the state’s attraction to public corporations. A current example of a management friendly trend in the case law had seen the recent decisions setting out the board’s authority to adopt bylaws under Section 109 of the Delaware General Corporation Law (DGCL), particularly those involving the shifting of fees in litigation against the corporation or its directors. The DGCL allows bylaws that address “the business of the corporation, the conduct of its affairs, and its rights or powers or the rights or powers of its stockholders, directors, officers or employees.” The broad parameters are, however, subject to limits. Bylaws cannot be inconsistent with the certificate of incorporation or “the law.” Law includes the common law. The Delaware courts have used the limitations imposed by “the law” to severely restrict the reach of shareholder inspired bylaws. The courts have not used the same principles to impose similar restraints on bylaws adopted by the board of directors. This can be seen with respect to bylaws that restrict or even eliminate the right of shareholders to bring actions against management and the corporation. In ATP Tour, Inc. v. Deutscher Tennis Bund the court approved a fee shifting bylaw that had littl relationship to the internal affairs of the corporation. The decision upheld the bylaw as facially valid.The decision ignored a number of obvious legal infirmities. Among other things, the decision did not adequately address the requirement in Section 109(b) that bylaws be consistent with “the law.” The decision obliquely acknowledged that the provisions would “by their nature, deter litigation” but otherwise made no effort to assess the impact of this deterrence on shareholders causes of action. The provision in fact had the practical effect of restricting, if not eliminating, litigation rights granted by the DGCL and the common law. Perhaps most significantly, however, the bylaws significantly limited common law rights of shareholders to bring actions against the corporation and the board. Given the high dismissal rates for these actions, fee shifting bylaws imposed a meaningful risk of liability on plaintiffs. Moreover, because judgments in derivative suits were paid to the corporation, shareholders serving as plaintiffs confronted the risk of liability without any offsetting direct benefit. By preventing suits in this area, the bylaw effectively insulated the behavior of boards from legal challenge. The ATP decision was poorly reasoned and overstepped acceptable boundaries. The management friendly decision threatened the preeminent role of Delaware in the development of corporate law. The decision raised the specter of federal intervention and the potential for meaningful competition from the states. Because the opinion examined the bylaw in the context of non-stock companies, the reasoning may remain applicable only to those entities and never make the leap to for-profit stock corporations. Nonetheless, the analysis reflects a management friendly approach that does not adequately take into account the impact of the provision on the rights of shareholders.

Brewing Behind Barbed Wire: An Archaeology of Saké at Amache

After the Japanese attack at Pearl Harbor on December 7, 1941, approximately 120,000 people of Japanese ancestry living on the west coast of the United States were forcibly removed from their home communities. These people were designated as "evacuees" by the U.S. Government and were incarcerated within a network of federal government facilities the largest of which were internment centers operated by the War Relocation Authority that held mostly U.S. citizens. The Granada Relocation Center (Amache) was the smallest of these internment centers. The presence of saké at Amache indicates that Japanese Americans continued important practices of daily life despite restrictions under confinement. This thesis investigates the practices of saké production and consumption at Amache and examines the importance of these practices in Japanese American daily life. In order to understand these practices, this research draws on multiple lines of evidence. This includes investigations of an assemblage of the material culture associated with saké, research into the history and methods of production and consumption, collection of oral histories, review of archival data, and the application of practice theory. These data provide insight into practices that are not well understood by researchers of Japanese American internment due to their illicit nature. This research endeavors to characterize how saké was produced and used at Amache and provides a way to understand how cultural practices maintain aspects of everyday life in ways that may have little to do with intentional resistance.

Comparative Evaluation of Groundwater Management Practices of the Ogallala Aquifer

Mining of groundwater, or extracting a larger quantity of water than what is naturally returned to the aquifer through recharge, has been occurring for more than fifty years. The minimal natural recharge to the Ogallala Aquifer makes sustainable use of this resource a daunting task for states across the High Plains that rely on it to support their well-established ways of life. This task is compounded when considering the different combinations of federal, state and local governance, as well as regional economic and social frameworks that each state overlaying the aquifer experiences. This project critically examines factors contributing to groundwater management successes and failures of three states that overlay the majority (87%) of this resource: Nebraska, Kansas and Texas.

Minority Coaches in the NFL: An Examination of Hiring Patterns as a Basis for Recommendations for Improved Employment Practices

Hiring minority coaches is a serious concern in the National Football League (NFL). The NFL's hiring practices are inconsistent, specifically for minority candidates. The author investigates why NFL teams underutilize minority coaches with research from Central Florida University and the University of Pennsylvania. Research findings suggest that minority hires positively affect the NFL, yet the hiring process remains weak. Case study examples show the poor decision-making trends of NFL personnel, implying that although minority coaches' success is better than non-minorities, the negative perception of minorities, as aspiring head coaches and leaders, is a barrier. As a result, the NFL has a unique opportunity to improve its hiring process by aligning its approach to hiring within the guidelines of federal law.
