Higher arithmetic Chow groups

We give a new construction of higher arithmetic Chow groups for quasi-projective arithmetic varieties over a field. Our definition agrees with the higher arithmetic Chow groups defined by Goncharov for projective arithmetic varieties over a field. These groups are the analogue, in the Arakelov context, of the higher algebraic Chow groups defined by Bloch. The degree zero group agrees with the arithmetic Chow groups of Burgos. Our new construction is shown to be a contravariant functor and is endowed with a product structure, which is commutative and associative.

Singular Bott-Chern classes and the arithmetic Grothendieck-Riemann-Roch theorem for closed immersions

We study the singular Bott-Chern classes introduced by Bismut, Gillet and Soulé. Singular Bott-Chern classes are the main ingredient to define direct images for closed immersions in arithmetic K-theory. In this paper we give an axiomatic definition of a theory of singular Bott-Chern classes, study their properties, and classify all possible theories of this kind. We identify the theory defined by Bismut, Gillet and Soulé as the only one that satisfies the additional condition of being homogeneous. We include a proof of the arithmetic Grothendieck-Riemann-Roch theorem for closed immersions that generalizes a result of Bismut, Gillet and Soulé and was already proved by Zha. This result can be combined with the arithmetic Grothendieck-Riemann-Roch theorem for submersions to extend this theorem to arbitrary projective morphisms. As a byproduct of this study we obtain two results of independent interest. First, we prove a Poincaré lemma for the complex of currents with fixed wave front set, and second we prove that certain direct images of Bott-Chern classes are closed.

Annotated list of the Phlebotominae (Diptera) of Suriname

Phlebotomine sandflies were collected between 1952 and 1984 at 30 localities in the tropical rainforest and savanna regions of Suriname. Thirty-nine species were identified in the collections (2 Brumptomyia, 37 lutzomyia), including two known vectors of cutaneous leishmaniasis, Lutzomyia flaviscutellata and L. umbratilis. Nineteen of the species are new records for Suriname. In the rainforest region, the commonest phlebotomines were L. squatniventris maripaensis (79.8%), L. umbratilis (8.4%) and L. flaviscutellata (6.3%) in human bait catches, L. umbratilis (26.2%), L. infraspinosa (23.9%) and L. trichopyga (8.3%) in CDC light traps and L. umbratilis (84.3%), L. whitmani (6.8%) and L. shannoni (4.3%) in collections from tree trunks. The mean incidence of cutaneous leishmaniasis from 1979-1985 was 4.9 per 1000 inhabitants for the rainforest region and 0.66 per 1000 for Surinameas a whole.

Identification and analysis of functional elements in 1% of the human genome by the ENCODE pilot project.

We report the generation and analysis of functional data from multiple, diverse experiments performed on a targeted 1% of the human genome as part of the pilot phase of the ENCODE Project. These data have been further integrated and augmented by a number of evolutionary and computational analyses. Together, our results advance the collective knowledge about human genome function in several major areas. First, our studies provide convincing evidence that the genome is pervasively transcribed, such that the majority of its bases can be found in primary transcripts, including non-protein-coding transcripts, and those that extensively overlap one another. Second, systematic examination of transcriptional regulation has yielded new understanding about transcription start sites, including their relationship to specific regulatory sequences and features of chromatin accessibility and histone modification. Third, a more sophisticated view of chromatin structure has emerged, including its inter-relationship with DNA replication and transcriptional regulation. Finally, integration of these new sources of information, in particular with respect to mammalian evolution based on inter- and intra-species sequence comparisons, has yielded new mechanistic and evolutionary insights concerning the functional landscape of the human genome. Together, these studies are defining a path for pursuit of a more comprehensive characterization of human genome function.

Modularity of the Consani-Scholten quintic

We prove that the Consani-Scholten quintic, a Calabi-Yau threefold over Q, is Hilbert modular. For this, we refine several techniques known from the context of modular forms. Most notably, we extend the Faltings-Serre-Livn´e method to induced four-dimensional Galois representations over Q. We also need a Sturm bound for Hilbert modular forms; this is developed in an appendix by José Burgos Gil and the second author.

Parasites of the flatfish Paralichthys adspersus (Steindachner, 1867) (Pleuronectiformes) from northern Chile

Three species of protistan and 22 species of metazoan parasites were obtained from a sample of 179 flatfish, (Paralichthys adspersus) taken-off Antofagasta, northern Chile. Prevalence of infection of seven parasites (Protista: 1, Copepoda: 2, Digenea: 1, Acantocephala: 1, Nematoda: 2) was significantly and positively correlated with host size. Host's sex do not seem to affect prevalence of infection, except for Nybelinia surmenicola, Capillaria sp. and Anisakis sp. (prevalence of infection significantly greater in males than females) and Philometra sp. (prevalence higher in females). Mean abundance is correlated with size in nine species (Protista: 1, Copepoda: 2, Digenea: 3, Acantocephala: 1, Nematoda: 2). Host's sex do not affect mean abundance, except for Cainocreadium sp. and Philometra sp.(mean abundance higher in females) and Nybelinia surmenicola, Capillaria sp. and Anisakis sp. (mean abundance higher in males).

Pla de millora de la docència del Departament de Matemàtica Econòmica, Financera i Actuarial

La finalitat del projecte (bianual 2007-09) era aconseguir una millora de la docència que imparteix el Departament de Matemàtica Econòmica, Financera i Actuarial. La nostra tasca principal ha consistit en obtenir uns indicadors que ens permetessin conèixer millor el nostre alumnat, per tal de tenir la màxima informació a l'hora de plantejar la revisió global que representa la implantació dels nous graus d’acord amb les directrius del procés de Convergència Europea. En aquest projecte han participat tots els coordinadors de les assignatures obligatòries del Departament i els tres Grups d’Innovació Docent formats per membres del Departament. S’han analitzat les dades de les assignatures des del curs 2000-01 fins 2006-07 per tal de tenir informació sobre l’eficàcia de cursar les assignatures d’Introducció a les Matemàtiques i la seva incidència en els aprovats a Matemàtiques I i II . També s’han estudiat dades sobre el col·lectiu de repetidors. Com a resultat d’aquest estudi i de les enquestes que s’han fet, s’han redactat dos articles: “Propuesta de mejora de la actuación docente a partir de las características del alumnado de primer curso de Matemáticas en la Facultad de Economía y Empresa de la Universidad de Barcelona” y “Estudio del perfil del alumnado de primer curso en la Facultad de Economía y Empresa de la Universidad de Barcelona” que s’han presentat a dos congressos d’Innovació Docent (Burgos, setembre-2009 i Vigo, juliol-2009).

Enfermedad neumocócica invasiva en adultos: Cambios en la presentación clinica y evolución tras la introducción del la vacuna neumococica conjugada heptavalente en niños

La introducción de la vacuna neumocócica conjugada ha modificado los serotipos causantes de enfermedad neumocócica invasiva (ENI). El objetivo de este estudio fue analizar las diferencias en la presentación clínica entre la época pre y postvacunal. Realizamos un estudio observacional de todos los adultos hospitalizados con ENI, entre 1997 y 2001 (periodo prevacunal), y de 2006 a 2009 (periodo postvacunal). Comparamos la incidencia, la distribución de serotipos y la presentación clínica entre ambos periodos. Nuestros hallazgos sugieren que la aparición de nuevos serotipos puede asociarse con un aumento de la incidencia de ENI, especialmente en adultos jóvenes, y una mayor severidad en la presentación.
