-fixed Hilbert schemes on surfaces, modular forms, and eta products
No full textLet be a complex surface with an effective action of a group which preserves the holomorphic symplectic form. Let be the generating function for the Euler characteristics of the Hilbert schemesof -invariant length subschemes. We show that its reciprocal, is the Fourier expansion of a modular cusp form of weight for the congruence subgroup . We give anexplicit formula for in terms of the Dedekind eta function for all 82possible . The key intermediate result we prove is of independentinterest: it establishes an eta product identity for a certain shifted thetafunction of the root lattice of a simply laced root system. We extend ourresults to various refinements of the Euler characteristic, namely the Ellipticgenus, the Chi- genus, and the motivic class.Comment: Published version. Greatly simplified proof of Proposition 3.
Efectividad del nepafenaco en la profilaxis de edema macular pseudofáquico en el Hospital Nacional Daniel Alcides Carrión de enero a diciembre del 2019
Get PDFLa catarata es una opacificación o cambio en la homogeneidad del cristalino dentro del ojo que involucra el epitelio anterior, cápsula, corteza o núcleo. Representa el 50% de ceguera en países de ingresos medios y bajos, pero está presente en sólo el 5% de la población en los países desarrollados. Actualmente, el tratamiento consiste en extirpar la catarata mediante facoemulsificación con una pequeña incisión e implante de una lente intraocular sintética (1).
La incidencia notificada de edema macular cistoide pseudofáquico varía mucho según los métodos utilizados para identificarlo y los criterios de diagnóstico utilizados para clasificar su aparición después de la cirugía de catarata. Los avances en el equipo quirúrgico han minimizado la necesidad de manipulación intraoperatoria. Al mismo tiempo, la identificación de pacientes con riesgo y la optimización de antiinflamatorios ha reducido la incidencia de edema macular clínicamente significativo entre el 0,1% y el 2,3%. El análisis de una gran base de datos situó la incidencia en el 1,17 % en pacientes con monoterapia con esteroides cuando no estaban presentes complicaciones operatorias o factores de riesgo reconocidos (2).
Hace 3 décadas la incidencia de edema macular con evidencia angiográfica fue 30%, pero las técnicas quirúrgicas y la mejora de fármacos han reducido la incidencia a 0.1%–3.8%. Su prevalencia alcanza su punto máximo entre las 4 y 6 semanas. Después de la operación, y la duración completa oscila entre 72 y 249 días; en la mayoría de las personas, se recupera espontáneamente dentro de los 6 meses (3)Submitted by Veronica RubinDeCelis ([email protected]) on 2023-01-13T18:22:33Z

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
