    How accurate are EOM-CC4 vertical excitation energies?

    We report the first investigation of the performance of EOM-CC4 - an approximate equation-of-motion coupled-cluster model, which includes iterative quadruple excitations - for vertical excitation energies in molecular systems. By considering a set of 28 excited states in 10 small molecules for which we have computed CC with singles, doubles, triples, quadruples, and pentuples and full configuration interaction reference energies, we show that, in the case of excited states with a dominant contribution from the single excitations, CC4 yields excitation energies with sub-kJ mol-1 accuracy (i.e., error below 0.01 eV), in very close agreement with its more expensive CC with singles, doubles, triples, and quadruples parent. Therefore, if one aims at high accuracy, CC4 stands as a highly competitive approximate method to model molecular excited states, with a significant improvement over both CC3 and CC with singles, doubles, and triples. Our results also evidence that, although the same qualitative conclusions hold, one cannot reach the same level of accuracy for transitions with a dominant contribution from the double excitations

    MeSH term explosion and author rank improve expert recommendations

    Information overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Activación de los sistemas arquitectónicos compactos. La construcción del mecanismo de proyección diagonal en la obra de Adolf Loos

    Get PDF
    [EN] The activation of compact architectural systems, built by attached spatial units –specialized, qualified, related to each other within a defined and regular container– requires specific tools capable of supplying the lack of dynamic, interstitial and communication spaces. The construction of Loos’ Raumplan implies the development of different relational mechanisms, based on the use of some of these tools. Among them, we can highlight one of great importance for its capacity to activate the interior space. Its construction arises from the evolution of fluctuation and frontality operations inherited from the architectural tradition and it gradually incorporates focal alterations that lead to the diagonal projection. Tools for the qualification of this diagonal perceptual mechanism are studied through a graphic analysis developed by the author.[ES] La activación de los sistemas arquitectónicos compactos, formados por unidades espaciales adosadas, especializadas, cualificadas, relacionadas entre sí en un contenedor definido y regular, requiere de herramientas específicas, capaces de suplir la carencia de espacios dinámicos, intersticiales y de comunicación. En la construcción del Raumplan, Adolf Loos desarrolla diferentes mecanismos relacionales. Entre ellos, destaca uno de gran capacidad dinamizadora del espacio interior. Su construcción parte de la evolución de las operaciones de fluctuación y frontalidad heredadas de la tradición arquitectónica para incorporar gradualmente alteraciones focales que conducen a la proyección diagonal. Mediante el análisis gráfico elaborado por el/la autor/a, se estudian las herramientas empleadas para la cualificación de este mecanismo perceptivo, que potencia la disociación entre el recorrido físico y perceptivo del observador.Toral Guinea, M.

    "Closing the R&D Gap, Evaluating the Sources of R&D Spending"

    Get PDF
    Both spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.

    Crime and Ornament : The Arts and Popular Culture in the Shadow of Adolf Loos

    No full text
    The editors of this collection have assembled 16 essays in response to Adolf Loos’ seminal essay on modern architecture “Crime and Ornament” (also included). As Ward and Miller note, some of the authors address Loos’ text directly, investigating the extent to which ornament problematizes form and function, while others use "ornament" as a vehicle for reflecting on issues related to contemporary art and culture.
