Root traces in fossil bones from the Huayquerian (Late Miocene) faunal assemblage of Telén, La Pampa, Argentina

One of the exposures of the Cerro Azul Formation in northern La Pampa (Argentina) has yielded a Huayquerian (Upper Miocene) faunal assemblage. The degree of bioerosion caused by roots on mandibles of Paedotherium minor (Mammalia, Notoungulata, Hege-totheriidae) was analyzed, in an attempt to throw light upon the events that affected the remains after deposition. According to the fea-tures observed on the specimens, two types of traces were identified. These were referred to the ethological categories Sphenoichnia and Corrosichnia. The first type is interpreted as the marks produced by rootlets growing on the skeletal element/sediment boundary after burial. These traces would indicate the development of a herbaceous cover on the soil where the remains were deposited and later bu-ried and may be another feature helpful in the identification of these paleosols. The second type implies a surface dissolution of the hard substrate, which in this case is the fossil itself. The characteristics of the remains that show this kind of trace may suggest that root growth has affected them only in recent stages.Uno de los afloramientos de la Formación Cerro Azul, ubicado en Telén, al norte de la provincia de La Pampa (Argentina), ha aportado fauna de vertebrados de edad Huayqueriense (Mioceno superior). Con la finalidad de conocer los acontecimientos que afectaron a los restos recuperados de esta asociación faunística después de su depósito, se analizó el grado de bioerosión producido por raíces. Se eligieron para este análisis los fragmentos mandibulares de Paedotherium minor (Mammalia, Notoungulata, Hegetotheriidae). Las características observadas en los materiales permitieron identificar dos tipos de trazas, que se atribuyeron a las categorías etológicas Sphenoichnia y Corrosichnia. El primer tipo de traza se interpreta como marcas de raicillas desarrolladas en la interfase elemento esquelético-sedimento después del enterramiento. Su presencia indicaría el desarrollo de una cobertura herbácea sobre el suelo mientras los restos fueron depositados. Constituye, además, otra evidencia que facilita la identificación de los paleosuelos presentes en este afloramiento. El segundo tipo de trazas está representado por marcas de mayor tamaño que las anteriores, con disolución superficial del sustrato que en este caso son los restos fósiles. Las características de los especímenes que presentan esta traza sugerirían que el desarrollo de raíces ha afectado los restos en etapas más recientes

Methodology for Designing Decision Support Systems for Visualising and Mitigating Supply Chain Cyber Risk from IoT Technologies

This paper proposes a methodology for designing decision support systems for visualising and mitigating the Internet of Things cyber risks. Digital technologies present new cyber risk in the supply chain which are often not visible to companies participating in the supply chains. This study investigates how the Internet of Things cyber risks can be visualised and mitigated in the process of designing business and supply chain strategies. The emerging DSS methodology present new findings on how digital technologies affect business and supply chain systems. Through epistemological analysis, the article derives with a decision support system for visualising supply chain cyber risk from Internet of Things digital technologies. Such methods do not exist at present and this represents the first attempt to devise a decision support system that would enable practitioners to develop a step by step process for visualising, assessing and mitigating the emerging cyber risk from IoT technologies on shared infrastructure in legacy supply chain systems

Doubly charged Higgs from ee-γ\gamma scattering in the 3-3-1 Model

We studied the production and signatures of doubly charged Higgs bosons in the process $\gamma e^- \rightarrow H^{--}E^+$, where $E^+$ is a heavy lepton, at the $e^-e^+$ International Linear Collider (ILC) and CERN Linear Collider (CLIC). The intermediate photons are given by the Weizs$\ddot{a}$cker-Williams and laser backscattering distributions. We found that significant signatures are obtained by bremsstrahlung and backward Comptom scattering of laser. A clear signal can be obtained for doubly charged Higgs bosons, doubly charged gauge bosons and heavy leptons

Migração de analógico para digital da rede sísmica do CIVISA mediante o desenho de um sistema de aquisição de dados e um rádio telemetria Wi-Fi

ABSTRACT: In September of 2016 a new digital communications network for the Azores Civil Protection (SRPCBA) was inaugurated providing digital, voice and Ethernet LAN telemetry capabilities to the Centre for Information and Seismovolcanic Surveillance of the Azores (CIVISA). During 2017, the telemetry links from all monitoring techniques were reconnected to the new communication system. In 2018 the CIVISA has started the migration from analogue to digital seismic stations and this process allow to liberate few short period geophones. At the CIVISA’s Information and Communication Technologies Support group (SATIC), motivated by the availability of sensors, an instrumentation project was started with the objective of develop affordable digital data acquisition system (DAS) for geophones and a Wi-Fi telemetry to transmit seismic data to the Data Acquisition Centre (CAD) of CIVISA, in Ponta Delgada. The DAS design uses Do It Yourself (DIY) modules for Internet of Things (IoT) applications, microcontrollers and low power computer boards.RESUMO: Em setembro de 2016, foi inaugurada uma nova rede de comunicações digitais para o Serviço Regional de Proteção Civil e Bombeiros dos Açores (SRPCBA), fornecendo capacidades de telemetria digital e voz ao Centro de Informação e Vigilância Sismovulcânica dos Açores (CIVISA). Em 2017, os enlaces de rádio das diversas técnicas de monitorização passaram para o sistema atual. Em 2018, o CIVISA iniciou a migração das estações sísmicas analógicas para digitais e este processo libertou alguns geofones. No grupo de Serviço de Apoio às Tecnologias de Informação e Comunicação (SATIC), motivado pela disponibilidade de sensores, iniciou-se um projeto com o objetivo de desenvolver um instrumento de aquisição de dados acessível (DAS) para geofones e um rádio Wi-Fi para retransmitir dados para o Centro de Aquisição de Dados (CAD), em Ponta Delgada. O DAS utiliza dispositivos Do It Yourself (DIY) para aplicações de Internet de Coisas (IoT) e computadores de baixa potência.info:eu-repo/semantics/publishedVersio

Dynamic real-time risk analytics of uncontrollable states in complex internet of things systems, cyber risk at the edge

The Internet of Things (IoT) triggers new types of cyber risks. Therefore, the integration of new IoT devices and services requires a self-assessment of IoT cyber security posture. By security posture this article refers to the cybersecurity strength of an organisation to predict, prevent and respond to cyberthreats. At present, there is a gap in the state of the art, because there are no self-assessment methods for quantifying IoT cyber risk posture. To address this gap, an empirical analysis is performed of 12 cyber risk assessment approaches. The results and the main findings from the analysis is presented as the current and a target risk state for IoT systems, followed by conclusions and recommendations on a transformation roadmap, describing how IoT systems can achieve the target state with a new goal-oriented dependency model. By target state, we refer to the cyber security target that matches the generic security requirements of an organisation. The research paper studies and adapts four alternatives for IoT risk assessment and identifies the goal-oriented dependency modelling as a dominant approach among the risk assessment models studied. The new goal-oriented dependency model in this article enables the assessment of uncontrollable risk states in complex IoT systems and can be used for a quantitative self-assessment of IoT cyber risk posture

Amadis of Gaul, Books I and II: A Novel of Chivalry of the 14th Century Presumably First Written in Spanish

Includes a new Introduction by John E. Keller In the long history of European prose fiction, few works have been more influential and more popular than the romance of chivalry Amadis of Gaul . Although its original author is unknown, it was probably written during the early fourteenth century. The first great bestseller of the age of printing, Amadis of Gaul was translated into dozens of languages and spawned sequels and imitators over the centuries. A handsome, valiant, and undefeatable knight, Amadis is perhaps best known today as Don Quixote’s favorite knight-errant and model. This exquisite English translation restores a masterpiece to print. A most welcome arrival. It\u27s availability opens up the possibility of a wider, general audience, and of teaching Amadis not only to the graduate comparatist, but also to the large undergraduate audience. -- Bulletin of Spanish Studies What made the original and its sequels international bestsellers in the early age of printing is bound to appeal to many modern readers. Amadis combines the sentimental with the chivalric, while adding bountiful measures of pure adventure and fantasy. -- La Coronica Set in and around England after the Roman era, but before the advent of Arthur, it tells the complex interwoven story of the adventures of Amadis, the greatest knight of all time. . . . This 16th century bestseller presents an exciting, past-paced and ultimately very entertaining story that modern readers should have little difficulty in appreciating. -- SF Sitehttps://uknowledge.uky.edu/upk_spanish_literature/1002/thumbnail.jp

Estima de la abundancia de palomas (Columba livia var.) de la ciudad de Barcelona y va­loración de la efectividad del control por eliminación de individuos

Uno de los métodos más comúnmente utilizados para el control de las poblaciones de palomas urbanas es la captura y eliminación selectiva de individuos. Con este método, la Agencia de Salud Pública de Barcelona (ASPB) eliminó entre 1991 y 2006, un total de 227.479 palomas. En el pre­sente trabajo se compara la abundancia de palomas de la ciudad de Barcelona estimada en 1991 (183.887±14.914), con los valores obtenidos en una nueva estima realizada en 2006, con un total de 256.663±26.210 (IC 95%) palomas. Mientras que en el centro de la ciudad la densidad de palomas no aumentó entre esos años, la densidad en todo el anillo que rodea el centro aumentó de forma significativa, conduciendo a un aumento global de toda la población urbana. El número de denuncias recibidas por distrito por molestias oca­sionadas por las palomas no se correlacionó con su abundancia. El esfuerzo de capturas por distrito realizado por la ASPB se correlacionó con la abundancia de palomas y no con el número de denuncias recibidas, lo que indica que las actuaciones realizadas siguen en general un protocolo técnico. La densidad de palomas por distrito se correlacionó signifi­cativamente con la densidad de habitantes de cada distrito, pero no con el número total de habitantes. Los datos presentados demuestran la baja efectividad de las medidas de control de palomas por eliminación de individuos, y abogan por un mayor énfasis en los métodos de control centrados en los factores limitantes de la especie, en concreto la oferta alimentaria y los lugares de nidificación. Palabras clave: Abundancia, Eliminación de individuos, Poblaciones de paloma, Columba livia var., Factores limitantes.Culling is one of the most com­monly used methods to control urban pigeon populations. The Barcelona Public Health Agency (ASPB) eliminated a total of 227,479 pigeons using this technique between 1991 and 2006. We compared the estimate of abundance of pigeons in Barcelona city in 1991 (183.667±14.914) with that in 2006 (256.663±26.210) (CI 95%). While pigeon density did not increase in the city centre during this period, density in a ring around the city increa­sed significantly, leading to a general increase in the urban population of these birds. The number of complaints regarding pigeons received per district did not correlate with abundance. ASPB culling per district correlated with abundance and not with numbers of complaints received, indicating interventions generally followed a technical protocol. Pigeon density per district correlated significantly with the human population density but not with the total number of inhabitants. Findings indicate the effectiveness of culling is low in this setting and suggest greater emphasis should be placed on control measures centered on limiting factors, particularly reduction of food availability and nest removal.

Assessing the Integrated Impact of Sustainable Innovation on Organisational Performance: An Empirical Evidence From Manufacturing Firms

Sustainable Development Goals (SDGs) have gained importance and the world is moving on a sustainability trajectory, which requires organisations to balance financial, environmental, and social dimensions of management. Companies are encouraged to adopt sustainable innovations that include resource efficiency, waste reduction, energy use, responsible behavior etc., to overcome environmental issues and incorporate societal aspects. However, the types of innovations that embrace the so-called triple bottom line philosophy have been tenuously investigated in relation to organisational performance of firms. Through an empirical study, this work investigates the relationship between sustainable innovation in its three dimensions and organisational performance, including stakeholder management, human resource management and process measures, in the context of Italian manufacturing companies. The results show that a greater emphasis on sustainable innovations has a positive impact on the organisational performance and competitive advantage of firms, revealing the key role of human capital and portraying important avenues for future research
