A special‐purpose Committee on DNA Sequences as Types was established at the XIX International Botanical Congress (IBC) in Shenzhen, China, in 2017, with a mandate to report to the XX IBC in Madrid in 2024 with recommendations on a preferred course of action with respect to potential amendments of the International Code of Nomenclature for algae, fungi, and plants to allow DNA sequences as types. This is the first in an expected series of papers from the Special‐purpose Committee on this issue. We set out the background to the establishment of the Committee, explore key issues around typification that are pertinent to the question of DNA sequences as types, enumerate pros and cons of allowing DNA sequences as types, and foreshadow options for future discussion and potential recommendations.

We assessed the scientific productivity of XMM- Newton by examining XMM- Newton publications and data usage statistics. We analyse 3272 refereed papers, published until the end of 2012, that directly use XMM- Newton data. The SAO/NASA Astrophysics Data System (ADS) was used to provide additional information on each paper including the number of citations. For each paper, the XMM- Newton observation identifiers and instruments used to provide the scientific results were determined. The identifiers were used to access the XMM-Newton Science Archive (XSA) to provide detailed information on the observations themselves and on the original proposals. The information obtained from these sources was then combined to allow the scientific productivity of the mission to be assessed. Since around three years after the launch of XMM- Newton there have been around 300 refereed papers per year that directly use XMM- Newton data. After more than 13 years in operation, this rate shows no evidence that it is decreasing. Since 2002, around 100 scientists per year become lead authors for the first time on a refereed paper which directly uses XMM- Newton data. Each refereed XMM- Newton paper receives around four citations per year in the first few years with a long-term citation rate of three citations per year, more than five years after publication. About half of the articles citing XMM- Newton articles are not primarily X-ray observational papers. The distribution of elapsed time between observations taken under the Guest Observer programme and first article peaks at 2 years with a possible second peak at 3.25 years. Observations taken under the Target of Opportunity programme are published significantly faster, after one year on average. The fraction of science time taken until the end of 2009 that has been used in at least one article is ∼90%. Most observations were used more than once, yielding on average a factor of two in usage on available observing time per year. About 20 % of all slew observations have been used in publications. The scientific productivity of XMM- Newton measured by the publication rate, number of new authors and citation rate, remains extremely high with no evidence that it is decreasing after more than 13 years of operations.

This paper examines the impact of the arrival of Airbnb on local consumption amenities in Madrid. We exploit the exogenous variation created by the timing and uneven distribution of Airbnb listings in the city to determine the impact on food and beverage establishments. Using an instrumental variable strategy, we find positive local effects on both the number of restaurants and their employees: an increase of 14 Airbnb rooms in a given census tract leads to almost one more restaurant, and the same increase in a given neighborhood generates 11 new tourist‐related employees. The results are robust to the specification and sample composition. This paper contributes to the literature on the economic impact of the platform economy on urban areas by providing evidence of market expansion externalities from short‐term rentals.

This article presents abstracts of research papers presented at the Third Congress of the European Society of Endodontology, held in Madrid, Spain on November 12-14, 1987. Bacterial contamination is now widely recognized as an important factor influencing the response of the dental pulp to operative trauma and to dental materials. In histologically based trials, approximately one third of the sections are normally stained specifically to demonstrate bacteria. There is little evidence in the literature of an evaluation of the sensitivity of such technique. The antibacterial activity of the vapours of camphorated phenol, iodine potassium iodide, aqueous 2 per cent glutaraldehyde, phenol, formaldehyde and cresophene has been tested in vitro against 20 species of bacteria frequently isolated from root canals.

The paper focuses on climate actions through water activity and energy synergies supporting a water public operator—Canal de Isabel II—to fight against climate change in the region of Madrid. Actions for its mitigation such as the generation of electricity through water treatment activity are undoubtedly a great tool to face climate change and mitigate CO2 emissions. Led by the Strategic Plan of Canal, a water & energy cycle has been designed that, taking advantage of the different processes carried out, and thanks to the appropriate technologies, allows the generation of 100% renewable electrical energy. Through its solar energy plan, Canal is making an important technological effort to reduce energy consumption, taking advantage of the extensive area the water company has for its operations. At the same time, wastewater solutions ans possibilities are becoming more attractive. This paper explains how the Canal is transforming biogas from wastewater treatment plants into fuel for vehicles. On adaptation, this document describes measures for increasing the availability of resources, reducing water consumption, and preparing for new challenges, provided that water remains an essential resource affordable and accessible to all. In this sense, Canal's main contribution and responsibility is to ensure its availability in the event of water scarcity and to avoid the effects of extreme weather phenomena. In addition, the paper presents important projects related to such adaptations as the tariff structure to discourage high superfluous uses of water or the water reclaimed production. This integrated approach to water and energy production and consumption represents an unbeatable strategy that is recommended for dealing with this global problem in a sustainable way. Canal's activities prove that a water company can aspire to be more sustainable through the implementation of integrated projects on the water and energy nexus. [ABSTRACT FROM AUTHOR]

This paper investigates the effect on academic performance of an exogenous educational reform that reduced the school calendar of non-fee-paying schools in the Madrid region (Spain) by approximately two weeks, leaving the basic curriculum unchanged. To identify the consequences of such a measure, we exploit the fact that it did not affect private schools (control group) and the existence of an external cognitive test that measures academic performance before and after its application in the region. We find that the reform worsened students' educational outcomes by around 0.13 of a standard deviation. This effect was especially strong in the subjects of Spanish and Mathematics. We further explored quantile effects across the distribution of exam scores, finding that the disruption had a more negative effect on students in the upper quartile than those in the lower quartile. Overall, the analysis shows a reduction in the gap across non-fee-paying schools and an increase in the gap between non-fee- and fee-paying schools. [ABSTRACT FROM AUTHOR]

The geography of school choice critically shapes families' educational opportunities. Residential segregation, social inequalities and the educational marketplace interact in complex ways and produce spatialised educational opportunities for families. This paper analyses the link between these dimensions and how they structure families' educational opportunities in the city of Madrid. Based on several administrative datasets that capture students' residential location, their socio-economic position, the schools they attend and the characteristics of school supply, our analysis reveals the uneven spatial distribution of the different school modalities in Madrid, where advantaged families and neighbourhoods have more diversified and socio-economically homogenous nearby schooling options. The results also depict the way the city is spatially divided along a continuum of 'privileged' residential and educational assets. The paper reflects on how reforms expanding school choice and diversification of the educational market undertaken by the regional government may have increased the link between residential and school segregation.

Critical debates in human geography have interrogated the changing political landscapes of the post‐2008 crisis period and the post‐democratic imprint of neoliberal reconfigurations in Europe. Moreover, geographers have offered insights into politicisation processes that disrupted the post‐crisis consensus, attesting to the possibility inherent within forms of democratic politics. Contributing to these debates, this paper critically engages with Chantal Mouffes "agonistics" approach, aiming to deliberate on the implicit geographies of her thought and bring forward the complex, messy, and multi‐scalar geographies of democratic politics. In so doing, the paper offers an empirically informed comparative perspective of two exemplary cases of governance changes. Social solidarity economy (SSE) and housing inform our re‐conceptualisation of "agonistics," through a plural reading of the co‐existing and at times conflicting forms of political agency and democratic politics of this period. By conceptualising the multiple and heterogeneous spatialities, modalities, and temporalities of agonistics in Athens and Madrid, we acknowledge their mutual constitution and distinct analytical validity for geographical thinking. Comparing across uneven geographical contexts elicits crucial tensions emanating from the heterogeneity of the two contexts and further allows us to distillate the diverse, yet complementary, logics and analytical dimensions of agonistics. Eventually, our contribution aims to problematise the distinction between "politics" and "the political" – as either neatly spatialised around pre‐given state spaces or understood exclusively as disruptive moments and ruptural events – and draw the attention to actually existing forms of agonistic politics. The paper critically engages with Chantal Mouffe's "agonistics" approach, aiming to deliberate on the implicit geographies of her thought and bring forward the complex, messy, and multi‐scalar geographies of democratic politics.

This paper analyzes patterns of residential segregation for many nationalities in Barcelona and Madrid during the 2008–2018 period. In the first year, the financial bubble burst, halting the exponential growth of immigrants and in the second, after the great recession, the arrival of immigrant population resumes. The multilevel analysis for the dissimilarity index is applied for the first time to Spanish cities. Complementing the results of global indices with the multilevel framework provides a richer and more detailed profile of segregation patterns. Based on these results, a typology of segregation patterns by nationalities was carried out. Global indices show higher segregation in Madrid than in Barcelona, and multilevel results evidence increasing and extending areas of high concentration of immigrants and mixing neighbourhoods. The cluster analysis demonstrates that, in this case, segregation patterns are not the same for continents or income levels of countries of origin. The results provide nuanced empirical evidence of place stratification and ethnic enclave models. [ABSTRACT FROM AUTHOR]

There has been an explosion of interest in health sciences applications of case-based reasoning (CBR), not only in the traditional CBR in medicine domain, but also in bioinformatics, enabling home health-care technologies, CBR integration, and synergies between CBR and knowledge discovery. This special issue features the best papers from the third workshop on CBR in the health sciences, held at ICCBR-05 in Madrid. It is the third in a series of exciting workshops, the first two of which were held at ICCBR-03, in Trondheim, Norway, and at ECCBR-04, in Madrid, Spain. The nine high-quality papers introduced here represent the research and experience of twenty-two authors working in eight different countries on a wide range of problems and projects. These papers illustrate some of the major trends of current research in CBR in the health sciences, and represent overall an excellent sample of the most recent advances of CBR in the health sciences.

This paper first presents a fuzzy expert system to identify and classify conventional two‐lane roads based on geometric characteristics. Both fuzzy and neuro‐fuzzy techniques have been used. Fuzzy logic has proved suitable to address this problem, since in this case, there is a variability of input information, and classical rules are not suitable to be used due to the uncertainty introduced by some combinations of the variables. Each road's geometric features were measured by sensors in an equipped vehicle, and are subsequently used to classify the roads according to their real condition. The conventional two‐lane roads used for this research are located in the Madrid Region, in Spain. This intelligent system may be used to update the road database regarding the assigned type to each conventional road, according to their present features and state. Also, a risk identification system has been developed to assess whether a vehicle is driving on a two‐lane road with an inappropriate speed, combining variables such as the former identification model, vehicle type, road longitudinal gradient, the angle covered by each horizontal curve, and the existence or not of an additional traffic lane. A fuzzy risk index is proposed for this approach. This fuzzy model may be useful to detect road sections where safety must be enhanced by revising the speed limit, since less safe situations may arise from travelling at unappropriated speeds.

An experimental campaign was carried out on full‐scale naturally corroded prestressed concrete (PC) beams without transverse reinforcement to investigate the corrosion effects on failure modes, shear capacity, and ductility. The analyzed PC beams, structural members of a thermal power plant, were subjected for 10 years to refrigerating wetting cycles with marine water. In this paper, the experimental results of four‐point bending tests, carried out at the Institute "Eduardo Torroja" in Madrid, are described. Before tests, a visual inspection was conducted to detect the damages induced by corrosion. During the tests, displacements and strains were measured by using linear variable displacement transducer (LVDT) and digital image correlation (DIC). After the tests, strands were removed from beams and cut in pieces, which were weighed to measure the mass loss. Last, it was proved that the residual life of PC beams, exposed to chloride attack, is strongly affected by corrosion, whose effects reduce the shear capacity in terms of both resistance and ductility.

Nowadays, the computer skills acquisition by Chemical Engineering (ChE) students is based on practical uses of specialized software packages in different applications. Process optimization courses use high‐level algebraic programming languages, such as GAMS (General Algebraic Modeling System) or AMPL (A Mathematical Programming Language), which are usually reserved for advanced programs in ChE degrees or ChE M.Eng. Commercial software for process optimization has several benefits, such as the possibility of facing complex numerical problems in a more efficient and straightforward way. By contrast, they typically present expensive license fees, and students usually require intense training to get the proper user‐level skills. The use of simpler and economic software tools may help overcoming these limitations. In this context, Microsoft (MS) Excel Solver tool is a widespread software with the potential to be used worldwide by any ChE student, and with the power to solve complex optimization problems at the academic level. In this paper, we introduce the application of MS Excel Solver for the optimization of a distillation sequence for the separation of a ternary mixture, including the heat integration in the definition of the problem. This is an MINLP problem, which usually requires specialized software performing stochastic methods, such as Simulated Annealing, to achieve a solution. In this regard, the approach to solve an optimization problem using the MS Excel Solver tool shown in this study was successfully employed by a student of ChE M.Eng. at Rey Juan Carlos University and the Autónoma University of Madrid in the development of her master thesis.

The purpose of this paper is to discover the extent to which women living homeless in Madrid (Spain) have been victims of intimate partner sexual violence (IPSV), analysing the connection between stressful life events (SLE) relating to violent victimisation and having suffered sexual assault by a partner. This study took place using a sample of women living homeless in Madrid (n = 136). The results obtained show that a high percentage of the women living homeless who were questioned had been victims of IPSV. The women interviewed, who had been victims of IPSV, had suffered, to a greater extent, SLEs relating to situations of violent victimisation, both during childhood and adolescence as well as in adulthood. The episodes of violent victimisation that seem to be the most common forerunners to IPSV are incidents of sexual abuse in childhood and adolescence. [ABSTRACT FROM AUTHOR]

This paper looks at the divergent economic trajectories of Barcelona and Madrid since Spain's transition to democracy. It highlights how Barcelona, the city that was better positioned four decades ago to emerge as the main Spanish economic hub, has lost out to Madrid. We argue that the contrasting trajectories of the two cities have less to do with the pull of Madrid as the capital of Spain, with the development of new infrastructure in the country, or with agglomeration economies, and more with institutional factors. A growing societal divide in Barcelona along economic, social, and identity lines has led to a greater breakdown of trust and to the development of strong groups with limited capacity to bridge with one another than in Madrid. This has entailed the emergence of negative externalities that have limited the economic potential for growth in Barcelona and facilitated the rise of Madrid as the main economic hub within Spain.

Local governments dispose of powerful tools like development funds that can be distributed among its different constituents to compensate economic disequilibrium originated by a complex array of factors. But it is always one of the hardest decisions to assign handouts to people who could think its own expectations are not being taken properly into account. Each stakeholder has different criteria to evaluate his needs, and to demand a particular investment effort. Since resources are very limited in local levels, city hall governments are pulled apart by those conflicting demands. The challenge of addressing them at the same time can be modelled as a multi‐criteria decision‐making. The aim of this paper is to show that the analytic hierarchy process (AHP) could work out the most acceptable distribution of the funds among the different city districts and neighbourhoods. The application of the model in Madrid shows that AHP: (a) allows to incorporate opposing demands; (b) increases the transparency of the decision‐making process; (c) eases the decentralization of governmental decisions; (d) enhances the legitimation of the final outcome; and (e) it is a scientific approach with great potential to be applied in similar domains where hard political decisions are needed.

Corrosion of prestressed concrete structures causes size reduction of strands, degradation of mechanical properties of steel, cracking of the surrounding concrete, and bond decay at steel‐to‐concrete interface. In this paper, a numerical approach able to take into account all the effects involved in the corrosion process by using nonlinear finite element analysis (NLFEA) and membrane or shell elements modeling is proposed. Two different strategies are adopted to model strands: the smeared and the discrete approaches. The results obtained using these latter strategies are validated by comparing NLFEA results with experimental measurements of a naturally corroded prestressed beam tested at the "Instituto de Ciencias de la Construcción Eduardo Torroja" in Madrid. Finally, pros and cons of the proposed modeling approach are critically analyzed, demonstrating that considering the actual spatial corrosion distribution is necessary to predict the position where failure occurs.

This paper examines the content and degree of uniformity of meta‐stereotypes among women living homeless in Madrid, Spain, and the differences with their male counterparts. The study was conducted utilizing a structured interview with a representative sample of men living homeless (n = 158) and a convenience sample of a similar size (n = 138) of women living homeless. The results show that the meta‐stereotypes of women living homeless in Madrid are characterized by mainly negative (e.g., consumers of alcohol, drug users, lazy, criminals) or indulgent (e.g., physically and psychologically worn out, rejected by society, sick) contents, with very limited positive (e.g., courteous, respectful, polite) contents, and a high degree of uniformity. There are no major differences in the content of meta‐stereotypes of the female interviewees in terms of their age, academic background, motherhood, or nationality. Compared to men in the same situation, a larger percentage of women living homeless agree with negative and indulgent meta‐stereotypes, and a smaller percentage agree with positive meta‐stereotypes.

Distillation is a very important operation for purification and separation in Chemical Engineering field. The determination of the optimal distillation sequence is key to minimize the total investment and operating cost and it can be posed as a mixed integer‐linear programming (MILP) problem. To solve them and due to the high number of variables and equations, it is required the use of specific software, for example, General Algebraic Modeling System or A Mathematical Programming Language. However, these software involve long training for the student to adequately harness them. The use of non‐specialized, widespread and easy to access software programs is a good opportunity to tackle the teaching of some typical optimization problems. One of them is the Microsoft Excel Solver Tool, accessible by any engineering student who usually learn its use in the first years of their degree, so that MS‐Excel is already known when students deal with optimization problems. Additionally, it is scarcely known that Microsoft Excel Solver may tackle both real and binary variables, so it is possible to leverage it for solving MILP problems. This paper presents an example of distillation sequences problem aimed to separate a mixture comprising four different compounds with a minimal operational cost (which constitutes a MILP optimization problem indeed) solved using Excel Solver tool. This methodology was taught successfully to the students of the Master of Chemical Engineering of Rey Juan Carlos University and Autónoma University of Madrid. [ABSTRACT FROM AUTHOR]

The traditional approach to the portfolio selection problem, the mean‐variance model, shows limitations because it assumes that any investment opportunity could be meaningfully measured in terms of means and variances of returns. The model should include other criteria, based on liquidity, the characteristics of return distributions, or environmental factors. To incorporate in the model these additional relevant aspects of the problem, alternative methodologies are needed. This paper deals with the problem by using a multicriteria approach based on compromise programming and various options to incorporate the prior information (the norm and the criteria weights). A simplified version of the model has been applied to the stocks included in the Madrid Stock Market IBEX35 index. This article is dedicated to the memory of our colleague and friend Professor Rafael Santamaría, one of the most brilliant Spanish Professors of Finance, who passed away on June 18, 2018, at the age of 57.

Summary: Propagation campaigns are carried out at different frequencies and geographical areas to characterize the slant‐path propagation channel. One of the objectives of the Alphasat Propagation Experiment is to evaluate the performance of satellite links that operate in the Q/V band. Since March 2014, the copolar level of the Alphasat Q‐band beacon signal has been measured at Universidad Politécnica de Madrid, Spain. The fade dynamics—fade and inter‐fade durations—results for three complete years (March 2014 to February 2017) of measurements are presented in this paper. Moreover, the experimental setup and receiver characteristics are described in detail. The collected data (with a mean availability of 97%) can be used to evaluate the atmospheric propagation impairments with a very good degree of accuracy. The probability of occurrence and the fraction of time of fade duration for an average‐year have been compared with the ITU‐R and CRC models with moderate agreement. For this reason, a modeling effort has been made leading to the conclusion that there is room for improvement in the models. [ABSTRACT FROM AUTHOR]

This paper presents new evidence on the differences in quality and achievement of public, private, and charter schools by using the educational outcomes for the more than 1,200 schools of the Madrid region over the period 2005-2009. By applying an external test including three different areas, mathematics, writing, and language, the evolution of the achievement of the pupils in the three different types of schools, public, charter, and private, are analyzed. Our results show that charter and, especially, private schools attain better results than public schools and are more responsive to its academic evolution, both at a lower cost. Private schools do their best to converge to the leading schools in their district in the previous year, whereas public schools do not seem to do so. This result holds even after controlling for the number of immigrants in the school, the age of the school, and its size. Also, the results seem quite robust, since we tested the relevance of different variables such as immigration, socioeconomic status, and foreign students and we obtained results that support our main hypothesis.

In the multilevel societies of hamadryas baboons, adult males can be attached to single one-male units (OMUs) or to clans containing several such OMUs. This paper examines the effect of male number and rivalry between males within a clan on their ability to compete for access to a clumped food resource. The data come from a study of a multilevel colony of hamadryas baboons (Papio hamadryas hamadryas) housed at the Madrid Zoo. The colony consisted of 12 harem-holding males and 40 sexually mature females, and was organized into five single OMUs and two clans (containing three and four OMUs, respectively). The top-ranking male of one of the clans was removed and later reintroduced, so the study involved an analysis of the composition of clans and OMUs and of the males' use of the feeding area across three study periods: preseparation, separation, and reintroduction. The findings reported indicate that both males and females derived clear advantages in the context of contest competition for access to clumped food if they were members of clans, because the males and females from large clans had a feeding advantage over those from smaller clans and single OMUs. Furthermore, rivalry among males within the clan reduced their ability to compete for food against males outside their clan. This paper provides empirical evidence for one of the potential advantages that hamadryas males may enjoy if they are attached to clans, and also provides empirical support for the general hypothesis that a large number of males in a group may provide fitness-related benefits to the group members, provided they are able to cooperate with each other.

This paper presents a model for explaining the international tourism flows to Madrid. The study is based primarily on examining the main characteristics of inbound tourism flows to Madrid in terms of its structure, evolution and composition by countries of origin of the visitors. According to the general principles of economic theory and the classic literature on tourism demand, a description of the main factors to be considered in determining tourism flows is presented. In the second part of the paper, by using data corresponding to 25 countries of origin and 16 years (1985–2000), an econometric (panel data) model is used to estimate the quantitative relationship between the level of inbound tourism to Madrid and its determinants. The model selected has been subject to a battery of diagnostics in order to test the validity of the assumptions that underlie the estimation. By using the Im–Pesaran–Shin test for unit roots the null hypothesis of non-stationarity of residuals is rejected and it is concluded that the model can be used for inference. The results show that income of the countries of origin of the travellers and costs of living of the tourists in Madrid relative to the costs of living in the origin country were among the most important factors of the international tourism demand. An interpretation of the results in terms of elasticities is presented in the last part of the paper, as well as their implications for tourism policy. Copyright © 2004 John Wiley & Sons, Ltd.

Invited for this month's cover picture is the group of Dr. Cristina Trujillo at the Trinity Biomedical Sciences Institute in Dublin (Ireland) and Prof. Ibon Alkorta at the CSIC in Madrid (Spain). The cover picture shows the possibility of reversibly storing hydrogen using metallic compounds as reactants to produce H2 gas and metallic dimers. Computational studies have been carried out to investigate these processes, as shown in the concept art by the Schrödinger equation. It was found that the formation and release of H2 is energetically favorable. These results are a promising starting point for further research of using coinage metals for storing hydrogen in light compounds. Read the full text of their Full Paper at10.1002/open.202100108.

Fossil mammal sites of late Miocene age ( ca 9 Ma) occur in hourglass-shaped, non-interconnected cavities up to 15 m deep, hosted in mudstone (mostly sepiolite), chert and carbonate bedrock in Cerro de los Batallones. This paper provides a model for the sedimentary infilling of the cavities, which functioned as traps for vertebrate faunas and contain one of the richest and best preserved Neogene mammal assemblages of the Iberian Peninsula. Generation of the mammal-bearing cavities started with the solution of underlying evaporites, which resulted in fissures that were subsequently enlarged by subsurface piping, a process rarely preserved in the ancient sedimentary record. The system of subterranean cavities evolved into a pseudokarst landscape, resulting in doline-like shafts reaching the ancient land surface. The sedimentary infilling of the cavities comprises both clastic and carbonate lithofacies that were investigated by outcrop observation, standard and scanning electron microscope petrography, mineralogical analysis, and stable isotope geochemistry. Gravel and breccia talus deposits, clast and mud-supported gravel, pebbly sandstone and mudstone are common detrital infill deposits mostly derived by overflow erosion of bedrock. The deposits containing the mammal bones are marls, and occur both in subsurface cavities and doline-like depressions. In the underground cavities, marlstone was mainly of clastic origin and accumulated in ponds scattered over the floor of the cavity. In contrast, marlstone deposits in the surface dolines formed mostly as a result of biochemical carbonate deposition in small shallow lakes subjected to fluctuation of the water level. The δ18O and δ13C carbonate values indicate different origins for the two kinds of marls. During the final phases of pipe infill the doline marlstone sealed the mammal sites, usually off-lapping the adjacent bedrock. [ABSTRACT FROM AUTHOR]

Please cite this paper as: del Rosal et al. (2011) Pandemic H1N1 influenza-associated hospitalizations in children in Madrid, Spain. Influenza and Other Respiratory Viruses 5(6), e544-e551. Objective To describe the epidemiological and clinical characteristics of children hospitalized with 2009 pandemic influenza (pH1N1) in Madrid, Spain. Patients/Methods We included patients less than 14 years of age admitted to one of 18 hospitals in Madrid, Spain, between May 1 and November 30, 2009 and diagnosed with pH1N1 by polymerase chain reaction. A retrospective chart review was conducted and data were compared by age, presence of high-risk medical conditions, and pediatric intensive care unit (PICU) admission. Results A total of 517 pH1N1 cases were included for final analysis. One hundred and forty-two patients (27·5%) had predisposing underlying illnesses, with immunosuppression (36 children, 7%) and moderate persistent asthma (34, 6·6%) being the most common ones. Patients with underlying medical conditions had longer hospital stays [median 5, interquartile range (IQR) 3-8 days, versus median 4, IQR 3-6, P < 0·001] and required intensive care (20·4% versus 5·9%, P < 0·001) and mechanical ventilation more frequently than previously healthy children. Globally, intensive care was required for 51 patients (10%) and invasive mechanical ventilation for 12 (2%). Pediatric intensive care unit admission was significantly associated with abnormal initial chest X-ray [Odds Ratio (OR) 3·5, 95% confidence interval (CI) 1·5-8·5], underlying neurological condition (OR 3·1, CI 1·2-7·5) and immunosuppression (OR 2·9, 1·2-6·8). Five patients (0·9%) died; two with severe neurological disease, two with leukemia, and one with a malignant solid tumor. Conclusions Children with underlying medical conditions experienced more severe pH1N1 disease. Risk factors for admission to the PICU included underlying neurological conditions, immunosuppression and abnormal initial chest X-ray. [ABSTRACT FROM AUTHOR]

Taxi cabs are a key feature of daily life in Madrid, which is one of the most important European cities. An exploratory study was undertaken in order to evaluate the quality of Madrid's taxi cab industry. This paper analyses the current situation by using the Taxi Cab Management Model (TCMM) which identifies the key processes for managing and operating a taxi cab service in any international city. The model provides a benchmark for measuring performance against other capital cities in developed nations. By comparing the results of this analysis with similar case studies of London, New York and Paris, areas of best practice are identified, as well as possible operational improvements. The study concludes that the Madrid taxi cab industry is ahead of cities like London, New York and Paris in terms of IT integration within the industry, but that some key issues need to be reviewed e.g. the potential for a more centralised fleet management system. One of the best features of the Madrid taxi cab industry was found to be the test for candidate drivers. It is well designed in terms of its user interface (candidates do not need to be computer literate), it has a large bank of questions (up to 6000) that are used randomly to generate examinations, and it offers a highly efficient way to assess candidates.

The terrorist train bombings in Madrid, Spain, on 11 March 2004 triggered a swift and massive medical response. 1 This paper analyses the pre-hospital response to the attacks to gain insight into current trends in disaster management among Madrid's Emergency Medical Services (EMSs). To this end, the existing emergency planning framework is described, the basic structures of the different EMSs are presented, and the attacks are briefly depicted before consideration is given to pre-hospital management. Finally, an explanation of the main underlying misconceptions in emergency planning and management in Madrid is provided to aid understanding of the origins of some of the problems detected during the response. These are attributable mainly to inappropriate planning rather than to mistakes in field-level decision-making. By contrast, many of the successes are attributable to individual initiatives by frontline medics who compensated for the lack of clear command by senior managers by making adaptive and flexible decisions.

The article discusses various reports presented at the 2005 EAGE annual conference in Madrid, Spain. The opening report of the session discussed the sub-basalt imaging problem in a geological context and the use of geological models prior to a joint inversion problem. A report is also presented on the problem of reconstruction of complex velocity fields by means of multiple geophysical measurements and simultaneous joint inversion within a pre-stack depth migration (PSDM) workflow.

Information about several papers discussed at the event Population Genetics and Genomics of Forest Trees: From Gene Function to Evolutionary Dynamics and Conservation, held in Madrid, Spain in October 2006 is presented. The ecological and evolutionary genetics of forest trees and associated organisms comprise a microcosm within this field. A major trend emerging in forest genetics research is the establishment of research programmes directed at the level of biological communities rather than single tree species.

This paper analyses the relevance of accounting fundamentals to inform about equity risk as measured by the cost of equity capital. Assuming the latter is a summary measure of how investors make decisions regarding the allocation of resources, the strength of the association between the cost of capital and the accounting-based measures of risk indicates how important these measures are for market participants when making economic decisions. To infer the cost of equity capital, we use the O'Hanlon and Steele's method, which is based on the residual income valuation model. Moreover, we use the insights from this model to provide a theoretical underpinning for the choice of the accounting variables related to risk. The sample refers to the non-financial firms listed in the Madrid Stock Exchange along the period 1987–2002. Our results support our initial expectations regarding the association between the cost of equity capital and the accounting-based risk variables, thereby supporting the usefulness of fundamental analysis to determine the risk inherent in share's future payoffs. In particular, we highlight the role of investing risk, which has been ignored in previous research. Our results are also robust to measures of risk other than the cost of capital such as the variability in total returns and the firm's systematic risk ( β). [ABSTRACT FROM AUTHOR]

As a contribution to portfolio selection analysis, we develop a compromise programming approach to the investor’s utility optimum on the Madrid Online Market. This approach derives from linkages between utility functions under incomplete information, Yu’s compromise set, and certain biased sets of portfolios on the efficient frontier. These linkages rely on recent theorems in multi–criteria literature, which allow us to approximate the investor’s utility optimum between bounds which are determined either by linear programming models or graphic techniques. Returns on 104 stocks are computed from capital gains and cash–flows, including dividends and rights offerings, over the period 1992–1997. The first step consists in normalizing the mean–variance efficient frontier, which is defined in terms of two indexes, profitability and safety. In the second step, interactive dialogues to elicit the investor’s preferences for profitability and safety are described. In the third step, the utility optimum for each particular investor who pursues a buy––hold policy is bounded on the efficient frontier. From this step, a number of portfolios close to the investor’s utility optimum are obtained. In the fourth step, compromise programming is used again to select one ‘satisficing’ portfolio from the set already bounded for each investor. This step is new with respect to previous papers in which compromise/utility models are employed. Computing processes are detailed in tables and figures which also display the numerical results. Extensions to active management policies are suggested. [ABSTRACT FROM AUTHOR]

In this paper we investigate the value-relevance of consolidated versus parent company accounting information. In particular we investigate the value relevance of the minority interest components of net total assets and earnings as currently reported and under the full entity approach to consolidated reporting. An Edwards-Bell-Ohlson valuation framework is used to generate results. By this means we cast light on the suitability of accounting regulation being developed based upon the entity or parent company theories of consolidation. We carry out the analysis in the Spanish context and the sample contains 474 observations of non-financial firms quoted in the Madrid Stock Exchange for the period 1991-97. The results from this analysis not only have domestic relevance but provide guidance of a more international nature relating to the impact of group definition, concepts of control and the most value relevant method of consolidated disclosure. The results show that, from a valuation perspective, consolidated information dominates non-consolidated, or parent company, information. However, neither the currently reported minority interest components of net total assets and earnings, nor their values under the full equity method of consolidation, are found to be value relevant. These results raise the question of whether group definitions based on the equity theory of consolidation are the most useful to investors. [ABSTRACT FROM AUTHOR]

Background: Pru p 7 has been reported as a major allergen in peach allergy, associated with severe clinical symptoms and related to IgE sensitisation to cypress pollen. The main objective of this study was to prospectively evaluate the frequency of sensitisation to Pru p 7 and its clinical relevance amongst pediatric patients with peach allergy in Madrid (Spain). Methods: Patients with a history of IgE‐mediated symptoms (oral allergy syndrome, urticaria/angioedema, rhinoconjunctivitis/asthma, gastrointestinal symptoms, or anaphylaxis) occurring within 2 h after peach intake or contact were prospectively recruited from February 2020 to September 2021. Skin tests, sIgE by ImmunoCAP® (Pru p 1, Pru p 3, Pru p 4, Pru p 7, and Cupressus arizonica) and oral food challenge (OFC) were performed. The study was approved by the local Ethics Committee (PI‐4513). Results: Ninety‐two patients were included (53.3% male); median age, 10 (IQR 6.0–14.75) years. Seventy‐four (80.4%) patients had a reaction after ingestion of fresh peach (25.0% from peel, 23.9% from pulp, and 44.6% from both). Fifteen (16.3%) patients were sensitised to Pru p 7. Upper airway symptoms, anaphylaxis, and grade 2 reactions were statistically more frequent in patients sensitised to Pru p 7. Seven (7.9%) patients presented with exercise as a cofactor, four of whom were sensitised to Pru p 7 (p =.001). Patients sensitised to Pru p 7 were significantly more likely to have a positive OFC result than patients who were not (p =.008). Four patients who reacted to peach at OFC were sensitised to Pru p 7. Specific IgE against Cupressus arizonica pollen was positive in 25 (62.5%) patients. Conclusions: Pru p 7 sensitisation was observed in 16.3% of our population and was related to severe reactions, upper airway symptoms, anaphylaxis, and the presence of an eliciting cofactor.

Traffic flow/volume data are commonly used to calibrate and validate traffic simulation models. However, these data are generally obtained from stationary sensors (e.g. loop detectors), which are expensive to install and maintain and cover a small number of locations in the transport network. On the other hand, Floating Car Data (FCD) are readily available at the network level, usually from a sample of vehicles. We present an indirect traffic flow estimation approach using transfer learning to address the traffic flow data scarcity and model generalization across cities. Using two cities (Paris and Madrid) as study areas, we demonstrate the indirect estimation using only exogenous features for flow prediction, mirroring limited predictive features without past link flows. Subsequently, we use the model pre‐trained on data from Paris city and test on data from Madrid city, and investigate the scenarios for successful transfer learning. Overall, the training set must adequately capture the flow‐speed relationship for successful indirect flow estimation. Transfer learning is beneficial when the data for the target task is minimal, in which case transferred models outperform newly trained models from scratch. Using real‐world and publicly available data, our approach and models can help scale a smaller traffic flow dataset to a larger sample across cities. [ABSTRACT FROM AUTHOR]

A new outbreak of monkeypox virus (MPXV) infection, a zoonotic infection endemic in Central and West Africa, is spreading throughout the world with new epidemiology and clinical features. Our aim was to characterize patients presenting to Dermatology emergency room with a MPXV infection between 15 May and 30 June 2022 in a tertiary hospital in Madrid, Spain. We collected 53 patients and describe their clinical, demographic and epidemiological characteristics and followed their evolution. Most of the patients were men who had sex with men with high‐risk sexual practices and no recent travels abroad. Most of them (91%) had had a sexually transmitted infection before. All patients had typical skin lesions consisting of vesicular‐pustular rash with central umbilication which was localized or disseminated. The most frequent extracutaneous symptoms were fever, painful regional lymphadenopathy and asthenia. Proctitis was present in more than one third of patients. All patients were diagnosed by real time polymerase chain reaction of samples obtained from skin lesions. Pharyngeal and/or rectal exudates demonstrated MPXV in 74% of patients. The current worldwide outbreak of MPXV infections shows epidemiological and clinical differences from previous ones. Clinicians should be aware of these characteristics to correctly diagnose this emerging disease. [ABSTRACT FROM AUTHOR]

Cold air pools (CAPs) are one of the most severe weather conditions experienced across many basins worldwide, related to episodes of extreme cold temperatures, poor air quality, and disruption of transportation networks. This study offers a basic climatology of CAPs in the southern Spanish Plateau and investigates its evolution since 1961 and their links with local, synoptic, and large‐scale climate variability. It is based on the comparison of meteorological records from two stations, one in the Sistema Central Range (Navacerrada, 1,894 m asl) and another at the plain (Madrid‐Barajas, 609 m asl). Accuracy and representativeness of both locations to depict the spatial and temporal variability of CAPs was also tested. CAPs days (defined as the simultaneous occurrence of a daily minimum temperature difference above 0.1°C between both stations) were found to occur year‐round, but the most frequent and intense occur in winter (NDJ). Some typical features of CAPs, such as local mesoscale processes (katabatic and anabatic flows) in connection with synoptic (advection of mid‐troposphere warm air masses during high‐pressure regimes) and hemispheric (a positive phase of the North Atlantic Oscillation) variability were also observed, leading to a sheltered boundary layer at the bottom of southern Spanish Plateau, decoupled from the free troposphere. By night, CAPs have maintained both their frequency and intensity, which means that the frequency of extremely cold nights on the plain has remained relatively stable (despite global warming). By day, an enhanced warming of the high‐elevation site has increased the temperature difference between the mountains and the plain during CAP days. [ABSTRACT FROM AUTHOR]

In this article, we explore a new category of analysis that we have called "discounted deaths," with which we seek to examine forms of dying occurring outside the scope of the triple meaning of the term "to count"—i.e., deaths that did not count, deaths that were not counted, and deaths for which there was no account. To do this, we look at the empirical case of elderly people who died in Madrid's nursing homes during the first wave of the pandemic, between March and May 2020. Compared to other affected groups, theirs were deaths that were deemed tolerable. People who died in nursing homes were first excluded from the assistance mechanisms available under the health emergency and then buried in solitude, away from their loved ones, who were not made aware of their situation until they were in their final moments.

Introduction: Adverse Events (AE) are one of the main problems in healthcare. Therefore, many policies have been developed worldwide to mitigate their impact. The Patient Safety Incident Study in Hospitals in the Community of Madrid (ESHMAD) measures the results of them in the region. Methods: Cross‐sectional study, conducted in May 2019, in hospitalised patients in 34 public hospitals using the Harvard Medical Practice Study methodology. A logistic regression model was carried out to study the association of the variables with the presence of AE, calibrated and adjusted by patient. Results: A total of 9975 patients were included, estimating a prevalence of AE of 11.9%. A higher risk of AE was observed in patients with surgical procedures (OR[CI95%]: 2.15[1.79 to 2.57], vs. absence), in Intensive Care Units (OR[CI95%]: 1.60[1.17 to 2.17], vs. Medical) and in hospitals of medium complexity (OR[CI95%]: 1.45[1.12 to 1.87], vs. low complexity). A 62.6% of AE increased the length of the stay or it was the cause of admission, and 46.9% of AE were considered preventable. In 11.5% of patients with AE, they had contributed to their death. Conclusions: The prevalence of AE remains similar to the previously estimated one in studies developed with the same methodology. AE keep leading to longer hospital stays, contributing to patient's death, showing that it is necessary to put focus on patient safety again. A detailed analysis of these events has enabled the detection of specific areas for improvement according to the type of care, centre and patient. [ABSTRACT FROM AUTHOR]

The Sixteenth Eilat Conference on New Antiepileptic Drugs and Devices (EILAT XVI) was held in Madrid, Spain on May 22–25, 2022 and was attended by 157 delegates from 26 countries representing basic and clinical science, regulatory agencies, and pharmaceutical industries. One day of the conference was dedicated to sessions presenting and discussing investigational compounds under development for the treatment of seizures and epilepsy. The current progress report summarizes recent findings and current knowledge for seven of these compounds in more advanced clinical development for which either novel preclinical or patient data are available. These compounds include bumetanide and its derivatives, darigabat, ganaxolone, lorcaserin, soticlestat, STK‐001, and XEN1101. Of these, ganaxolone was approved by the US Food and Drug Administration in March 2022 for the treatment of seizures associated with cyclin‐dependent kinase‐like 5 deficiency disorder in patients 2 years of age and older.

The Eilat Conferences have provided a forum for discussion of novel treatments of epilepsy among basic and clinical scientists, clinicians, and representatives from regulatory agencies as well as from the pharmaceutical industry for 3 decades. Initially with a focus on pharmacological treatments, the Eilat Conferences now also include sessions dedicated to devices for treatment and monitoring. The Sixteenth Eilat Conference on New Antiepileptic Drugs and Devices (EILAT XVI) was held in Madrid, Spain, on May 22–25, 2022 and was attended by 157 delegates from 26 countries. As in previous Eilat Conferences, the core of EILAT XVI consisted of a sequence of sessions where compounds under development were presented and discussed. This progress report summarizes preclinical and, when available, phase 1 clinical data on five different investigational compounds in preclinical or early clinical development, namely GAO‐3‐02, GRT‐X, NBI‐921352 (formerly XEN901), OV329, and XEN496 (a pediatric granular formulation of retigabine/ezogabine). Overall, the data presented in this report illustrate novel strategies for developing antiseizure medications, including an interest in novel molecular targets, and a trend to pursue potential new treatments for rare and previously neglected severe epilepsy syndromes.

The atmosphere plays a significant role in degrading Ka‐band (32 GHz) radio and optical communications for single antenna communications as well as degrading interferometric measurements such as used for radio astronomy and multi‐antenna arrays. Higher frequencies such as deep space Ka‐band (32 GHz) and near‐Earth K‐band (26 GHz) are more susceptible to this atmospheric degradation than at the lower frequency bands of S‐band (2.3 GHz) and X‐band (8.4 GHz). The various sources of atmospheric degradation include rain attenuation, cloud attenuation, gaseous attenuation, atmospheric noise temperature increase, and scintillation. For this study, we have focused on the strength of the turbulence caused principally by the wet atmosphere represented by the refractive index structure parameter Cn2, which is a measure of the variance of the refractive index over small incremental distances along the signal path, and thus is a strong function of water vapor variations at microwave frequencies. Here we provide a comprehensive study of this parameter derived from years of Site Test Interferometer measurements acquired from a variety of climates. We found that the strongest diurnal variation and correlation of Cn2 measurements with its model occurred for Goldstone, California representing a high‐desert climate, while weaker correlations were found for Kennedy Space Center representing a sub‐tropical climate, and Canberra, Australia and Madrid, Spain representing temperate climates. We quantified periods where the strongest correlation was observed such as Goldstone summers (as high as 0.7 for ∼3‐day periods) where the days are typically hot and humid while nights tend to be colder and drier. Key Points: Refractive index structure constants were derived from Site Test Interferometer (STI) phase delay scatter for a variety of climatesThe strongest diurnal variation in this parameter occurred for the high‐desert site at Goldstone, CaliforniaWe found good correlation with the derived STI structure parameters and a model which included planetary boundary layer height [ABSTRACT FROM AUTHOR]

We analyse the transmission factors shaping the spatial distribution of COVID‐19 infections during the distinct phases of the pandemic's first wave in Madrid, Spain, by fitting a spatial regression model capturing neighbourhood effects between municipalities. Our findings highlight that factors such as population, mobility, and tourism were instrumental in the days before the national lockdown. As a result, already in the early part of the lockdown phase, a geographical pattern emerged in the spread of the disease, along with the positive (negative) impact of age (wealth) on virus transmission. Thereafter, spatial links between municipalities weakened, as the influences of mobility and tourism were eroded by mass quarantine. However, in the de‐escalation phase, mobility reappeared, reinforcing the geographical pattern, an issue that policymakers must pay heed to. Indeed, a counterfactual analysis shows that the number of infections without the lockdown would have been around 170% higher. [ABSTRACT FROM AUTHOR]

The article presents a study conducted at the Veterinary Teaching Hospital in Madrid, Spain that examined the survival time of dogs with inflammatory mammary cancer which are given palliative treatment and chemotherapy. The study involved seven dogs that were treated with a combination of palliative treatment and chemotherapy and 23 dogs treated with only palliative treatment. It is found that the dogs in the two groups have no significant differences in characteristics.

This paper studies the use of the terms ‘separatist’ and ‘terrorist’ in the aftermath of Madrid's 3/11 attacks and their discursive implications from a critical perspective, and attempts to throw some light on whether there are sufficient grounds to substantiate the voices against ‘separatist’ when reporting on attacks carried out by the militant group Eta that involved killings. The study is divided into three sections, which examine, first, the choice(s) made by Spanish news websites and the intratextual cohesion devices used by the authors, and, secondly, the terms and devices used in British and American news websites. Finally, we shall discuss the ideological implications that might lie beneath the preference for ‘separatist’ in Anglophone media, and comment on the problems derived from it. [ABSTRACT FROM AUTHOR]
