Dos vidas, una revolución : Epistolario de José Gregorio y Agustín Gutiérrez Moreno (1808-1816)
No full textLas cartas que se cruzaron los hermanos José Gregorio y Agustín Gutiérrez Moreno, recopiladas en este libro, se enmarcan con notable precisión en el ciclo recorrido por la revolución neogranadina. En primer lugar, porque comienzan con la recepción de la infausta e incierta noticia del apresamiento de la familia real española en 1808, y vienen a cerrarse con la llegada de las tropas de Morillo a Santafé en 1816, invasión que baja temporalmente el telón de la revolución. En segundo lugar, porque se abren mostrando la profesión de fe lealista de la que participaban todos los neogranadinos, y acaban cuando José Gregorio es fusilado por haber atentado contra aquel poder monárquico; y en tercer lugar, porque se inician cuando los hermanos Gutiérrez aún se sienten parte de la nación española, y concluyen en el momento en que Agustín consigue armas y trabaja de diversas formas por cimentar la ruptura con la madre patria

Origin, evolution and diversification of extant amphibians
No full textAmphibians constitute one of the major branches of the vertebrate tree of life, with nearly 8,400 extant species currently inhabiting most terrestrial and freshwater habitats in temperate and tropical landmasses worldwide. The extant amphibians (Lissamphibia) encompass three orders of markedly distinct morphologies and life styles. The most diverse of these are the Anura (frogs and toads) that have short, tailless bodies with long, powerful hind limbs for jumping. Less diverse Caudata (salamanders and newts) have slender bodies with proportionally paired limbs and long tails. And the smallest group are the Gymnophiona (caecilians) that have elongated, limbless bodies adapted for burrowing. Extant amphibians have a long evolutionary history that probably extends back more than 300 million years ago, and are key for understanding the colonization of terrestrial environments by early tetrapods. This chapter discusses the state-of-knowledge of the origin and ancestry, phylogeny and evolution, and diversification of extant amphibians. Since the beginning of the XXI century, the vast accumulation of data from multiple sources (molecular, genomic, paleontological, morphological, ecological, behavioural, biogeographical) as well as the spread of integrative approaches have shed light on long hotly debated issues on the origin and evolution of this important group of vertebrates.Depto. de Biodiversidad, Ecología y EvoluciónFac. de Ciencias BiológicasTRUEpu

Instantaneous Kinematics and Singularities of Two Types of Under-Actuated Parallel Wrists
No full textS-(nS)PU-SPU and S-(nS)PU-2SPU are two out of three types of under-actuated wrists that are generated from the “ordinary” wrists of type S-3SPU (fully-parallel wrists), by replacing a spherical pair (S) with a nonholonomic spherical pair (nS) according to the rules stated in [1]. Position analysis, controllability, and path planning of these two wrist types have been addressed and solved in two previous papers [2, 3] of this author. Their kinetostatics and singularity analysis have not been addressed, yet; and they are studied in this paper.

José Eusebio Caro y Gregorio Gutiérrez González: variaciones de la poesía romántica colombiana en el siglo XIX
No full textEn este artículo se propone el análisis de la poesía de Gregorio Gutiérrez González y José Eusebio Caro, como eje que permite reflexionar algunos alcances, variantes y características de la poesía romántica colombiana del siglo XIX. Se analiza como la mezcla entre sensibilidad romántica, proyecto nacionalista y doctrina religiosa, constituye el germen del conflicto poético de la poesía nocturna de Gutiérrez y Caro; el cual determina sus limitaciones y mayores logros poéticos.</jats:p

No full textA ".xlsx" file which provides data used by Gregorio González-Alcaide & collaborators in the article “Evolution of cooperation patterns in psoriasis research: co-authorship network analysis of papers in Medline (1942-2013).” The worksheet “labels” describes every variable. The worksheet “dataset” presents the following data:
PMID: PubMed Identifier for indexed documents in Pubmed used for the study. PMIDs do not change over time or during processing and are never reused.
DP: Date that the article was published.
FAU: Author name for articles published. From 2002 forward, the full author name of authors is provided, if available.
FAU-Revised: Author name after cleansing process. A standardization process of the variations in signatures from single authors was carried out. The main discrepancies we found were caused by one or more first or last names being included, the authors’ first names being either spelled out or abbreviated to the initials, and typos
