Phenylhydrazinium (6-carboxypyridine-2-carboxylato)(pyridine-2,6-dicarboxylato)cobaltate(II)–pyridine-2,6-dicarboxylic acid–water (1/1/3)
Consuelo Yuste,Manuela Ramos Silva,Mohammad Ghadermazi,Fariba Feizi
Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810048191
Abstract: The asymmetric unit of the title compound, (C6H9N2)[Co(C7H3NO4)(C7H4NO4)]·C7H5NO4·3H2O, contains one (6-carboxypyridine-2-carboxylato)(pyridine-2,6-dicarboxylato)cobaltate(II) anion, one phenylhydrazinium cation, one pyridine-2,6-dicarboxylic acid molecule and three uncoordinated water molecules, part of which are disordered. The CoII ion is coordinated by a pyridine-2,6-dicarboxylate ion and a 6-carboxypyridine-2-carboxylate ligand almost perpendicular to each other [the angle between the least-squares planes is 87.38 (4)°] and is surrounded by two O atoms and two N atoms in the equatorial plane and two O atoms in axial positions, resulting in a distorted octahedral coordination geometry. There is an extensive three-dimensional network of O—H...O and N—H...O hydrogen bonds, which link the components.
Monoclinic polymorph of 2-(pyrimidin-2-ylsulfanyl)acetic acid
Manuela Ramos Silva,Pedro S. Pereira Silva,Consuelo Yuste,José A. Paixão
Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811000651
Abstract: The title compound, C6H6N2O2S, is a new polymorphic form of 2-(pyrimidin-2-ylsulfanyl)acetic acid. Unlike the previous orthorhombic polymorph [Pan & Chen (2009) Acta Cryst. E65, o652], the molecules are not planar: the aromatic ring makes an angle of 80.67 (17)° with the carboxyl plane. In the crystal, molecules are linked by O—H...N hydrogen bonds into chains along [overline{1}02].
Brain Diseases in Mesopotamian Societies
Piedad Yuste
Brain. Broad Research in Artificial Intelligence and Neuroscience , 2010,
Abstract: In ancient Mesopotamia were not practiced neither autopsies nor dissections, so the internal organs of human body were known only from occasional inspections on wounds and injuries. The brain was considered as a part of the head and was not related to mental activity. However, Babylonian and Assyrian physicians were able to identify the symptoms of many diseases that affect this organ. We will make here a brief overview of them.
Circuit neuroscience: the road ahead
Rafael Yuste
Frontiers in Neuroscience , 2008, DOI: 10.3389/neuro.01.017.2008
Abstract: It is difficult to write about grand challenges in our field without pontificating or pretending to show a degree of certainty in assessing the field that I do not possess. I would rather comment on a few of the issues that particularly worry me. Therefore, this article is just a snapshot of our field now, as I see it, and encourage readers to read it as the opinion of just one of their colleagues.

Leer e interpretar la imagen para traducir
Yuste Frías, José;
Trabalhos em Linguística Aplicada , 2011, DOI: 10.1590/S0103-18132011000200003
Abstract: from the translatological standpoint of paratranslation, images can ben considered in translation as iconic paratexts whose symbolic reading and interpretation call for a certain methodological and paratranslational discipline regarding the creation and development of the translator's perspective. based on two different corpora, -on the one hand the sketchs of would-be "pictograms" by xunta de galicia, on the other, the "new faces" of kinder chocolate boxes- josé yuste frías shows in this paper that images in translation are not universal. manipulation of images entails not only symbolic implications, but also ideological, political, social and cultural questions that have a key import in the final presentation of the products of translation.
Was the Adoption of Codes of Conduct by the Transnational Companies Effective for the Bringing to an End of Apartheid in South Africa?
Olga Estadella Yuste
Revista CIDOB d'Afers Internacionals , 1995,
Abstract: The international community frequently imposes sanctions of an economic character on those countries which blatantly violate the most fundamental human rights. This article intends to analyse other possible sanction mechanisms: the codes of conduct. The example used has been South Africa and the adoption of codes of conduct by thosetransnational companies operating in this country. The results of the study show that in spite of the voluntary character of the adopted codes at regional, national and private level, numerous companies have put them into practice, pressurizing in an indirect manner for the elimination of the apartheid regime. In this way, it would be convenient to remember on other occasions that codes of conduct can also contribute to the defense of human rights in the international community.
Los debates del Estatuto de Autonomía de Catalu a en las cortes republicanas (mayo-agosto de 1932). El idioma catalán y el sistema escolar
Xavier Tornafoch Yuste
Historia Actual Online , 2004,
Abstract: La discusión del Estatuto de Catalu a en el marco de la constitución del nuevo régimen republicano, surgido de las elecciones municipales del 12 de abril de 1931, evidenció las diferencias que persistían en el seno de la comunidad política espa ola sobre esta cuestión. Los partidos republicanos catalanes, decididamente favorables al autogobierno de Catalu a se enfrentaron en las Cortes a la mayoría de organizaciones espa olas, de derecha y de izquierda, reacias a conceder una autonomía política a la región catalana. Los dos aspectos que más debate suscitaron fueron la oficialidad del idioma catalán y el sistema escolar. Esta polémica parlamentaria se llevó a cabo entre los meses d emayo y agosto del a o 1932.

Automatic Reconstruction of Neural Morphologies with Multi-Scale Tracking
Anna Choromanska,Rafael Yuste
Frontiers in Neural Circuits , 2012, DOI: 10.3389/fncir.2012.00025
Abstract: Neurons have complex axonal and dendritic morphologies that are the structural building blocks of neural circuits. The traditional method to capture these morphological structures using manual reconstructions is time-consuming and partly subjective, so it appears important to develop automatic or semi-automatic methods to reconstruct neurons. Here we introduce a fast algorithm for tracking neural morphologies in 3D with simultaneous detection of branching processes. The method is based on existing tracking procedures, adding the machine vision technique of multi-scaling. Starting from a seed point, our algorithm tracks axonal or dendritic arbors within a sphere of a variable radius, then moves the sphere center to the point on its surface with the shortest Dijkstra path, detects branching points on the surface of the sphere, scales it until branches are well separated and then continues tracking each branch. We evaluate the performance of our algorithm on preprocessed data stacks obtained by manual reconstructions of neural cells, corrupted with different levels of artificial noise, and unprocessed data sets, achieving 90% precision and 81% recall in branch detection. We also discuss limitations of our method, such as reconstructing highly overlapping neural processes, and suggest possible improvements. Multi-scaling techniques, well suited to detect branching structures, appear a promising strategy for automatic neuronal reconstructions.
