Siete semanas en bote en el territorio del alto rÃo Coco en Nicaragua: Viaje de exploración misionera de los Hermanos Grossman y Garth de septiembre a noviembre de 1905
Este artÃculo es la crónica de un viaje de ida y regreso emprendido por los hermanos misioneros Grossman y Garth por el alto rÃo Coco y los rÃos Waspuk, Pis Pis y Bocay a finales de 1905. En dicho viaje, sus anotaciones revelan la existencia de algunas comunidades importantes (Wasla, Saupuka, Kisalaya, Leymus, etcétera) que visitaron en su recorrido; describen las crecidas de los rÃos y de la visita que hicieron al rey miskito Andrew. Fueron testigos de costumbres ancestrales, de tal manera que describe ritos de curación entre los indÃgena, alimentos que consumÃan, entre otras caracterÃsticas, tanto de los miskitos como de los sumos. Aunque la mayor parte del recorrido fue sobre rÃos, también participaron en cabalgatas en la selva, por donde pudo observar plantaciones de hule, caña de azúcar, cacao y bananos
Siete semanas en bote en el territorio del alto rÃo Coco en Nicaragua: Viaje de exploración misionera de los Hermanos Grossman y Garth de septiembre a noviembre de 1905
This article correspond to the chronicle of a trip, both ways, through the high Coco River and the rivers Waspuk, Pis Pis and Bocay carried out by the missionary brothers Grossman and Garth by the end of 1905. The annotations of the author reveal the existence of important communities in places that they visited during their journey, places like Wasla, Saupuka, Kislaya, Leymus and some others. He dwells on the rivers’ floods and the visit that they made to the miskito King Andrew. He was witness to ancestral traditions, so that he can describe healing rituals among the Indians, nourishments that they consumed and other ancient customs, both among the miskito as well as the sumu. Albeit the voyage was over water most of the time, they also participated on cavalcades trough the rain forest, where they could observe rubber, sugar cane, cacao and banana plantations.

Cluster mass estimation through Fair Galaxies
We analyse a catalogue of simulated clusters within the theoretical framework
of the Spherical Collapse Model (SCM), and demonstrate that the relation
between the infall velocity of member galaxies and the cluster matter
overdensity can be used to estimate the mass profile of clusters, even though
we do not know the full dynamics of all the member galaxies. In fact, we are
able to identify a limited subset of member galaxies, the 'fair galaxies',
which are suitable for this purpose. The fair galaxies are identified within a
particular region of the galaxy distribution in the redshift (line-of-sight
velocity versus sky-plane distance from the cluster centre). This 'fair region'
is unambiguously defined through statistical and geometrical assumptions based
on the SCM. These results are used to develop a new technique for estimating
the mass profiles of observed clusters and subsequently their masses. We tested
our technique on a sample of simulated clusters; the mass profiles estimates
are proved to be efficient from 1 up to 7 virialization radii, within a typical
uncertainty factor of 1.5, for more than 90 per cent of the clusters
considered. Moreover, as an example, we used our technique to estimate the mass
profiles and the masses of some observed clusters of the Cluster Infall Regions
in the Sloan Digital Sky Survey catalogue. The technique is shown to be
reliable also when it is applied to sparse populated clusters. These
characteristics make our technique suitable to be used in clusters of large
observational catalogues.Comment: 11 pages, 11 figures, 5 tables - Slightly revised to match the

On intermediate subfactors of Goodman-de la Harpe-Jones subfactors
In this paper we present a conjecture on intermediate subfactors which is a
generalization of Wall's conjecture from the theory of finite groups. Motivated
by this conjecture, we determine all intermediate subfactors of
Goodman-Harpe-Jones subfactors, and as a result we verify that
Goodman-Harpe-Jones subfactors verify our conjecture. Our result also gives a
negative answer to a question motivated by a conjecture of
Aschbacher-Guralnick.Comment: To appear in Comm. Math. Phy
Cellulose-derived oligomers act as damage-associated molecular patterns and trigger defense-like responses
The plant cell wall, often the site of initial encounters between plants and their microbial pathogens, is composed of a complex mixture of cellulose, hemicellulose, and pectin polysaccharides as well as proteins. The concept of damage-associated molecular patterns (DAMPs) was proposed to describe plant elicitors like oligogalacturonides (OGs), which can be derived by the breakdown of the pectin homogalacturon by pectinases. OGs act via many of the same signaling steps as pathogen- or microbe-associated molecular patterns (PAMPs) to elicit defenses and provide protection against pathogens. Given both the complexity of the plant cell wall and the fact that many pathogens secrete a wide range of cell wall-degrading enzymes, we reasoned that the breakdown products of other cell wall polymers may be similarly biologically active as elicitors and may help to reinforce the perception of danger by plant cells. Our results indicate that oligomers derived from cellulose are perceived as signal molecules in Arabidopsis (Arabidopsis thaliana), triggering a signaling cascade that shares some similarities to responses to well-known elicitors such as chitooligomers and OGs. However, in contrast to other known PAMPs/DAMPs, cellobiose stimulates neither detectable reactive oxygen species production nor callose deposition. Confirming our idea that both PAMPs and DAMPs are likely to cooccur at infection sites, cotreatments of cellobiose with flg22 or chitooligomers led to synergistic increases in gene expression. Thus, the perception of cellulose-derived oligomers may participate in cell wall integrity surveillance and represents an additional layer of signaling following plant cell wall breakdown during cell wall remodeling or pathogen attack
CP violation in neutrino oscillations and new physics
We consider future experiments to detect CP violation in neutrino
oscillations and discuss how to test that all asymmetries are indeed described
in terms of the single leptonic Jarlskog invariant as predicted in the absence
of new physics effects.Comment: 28 pages, 15 figures, references added, version to appear in NP
Models of Neutrino Masses: Anarchy versus Hierarchy
We present a quantitative study of the ability of models with different
levels of hierarchy to reproduce the solar neutrino solutions, in particular
the LA solution. As a flexible testing ground we consider models based on
SU(5)xU(1)_F. In this context, we have made statistical simulations of models
with different patterns from anarchy to various types of hierachy: normal
hierarchical models with and without automatic suppression of the 23
(sub)determinant and inverse hierarchy models. We find that, not only for the
LOW or VO solutions, but even in the LA case, the hierarchical models have a
significantly better success rate than those based on anarchy. The normal
hierachy and the inverse hierarchy models have comparable performances in
models with see-saw dominance, while the inverse hierarchy models are
particularly good in the no see-saw versions. As a possible distinction between
these categories of models, the inverse hierarchy models favour a maximal solar
mixing angle and their rate of success drops dramatically as the mixing angle
decreases, while normal hierarchy models are far more stable in this respect.Comment: v1: 28 pages, 12 figures; v2: 34 pages, 14 figures, updated previous

Performance analysis based on impact variables of a highway bridge under seismic actions considering uncertainties
Los puentes son sistemas de conexión de gran importancia socio-económica. Se presenta la evaluación del desempeño de un puente de vigas de hormigón pretensado existente ubicado en zona de alta sismicidad, donde los objetivos se expresan como el riesgo aceptable de pérdidas económicas por daños a la estructura, a las personas, y especialmente por interrupción de servicio, en función de la peligrosidad sÃsmica. Debido a la existencia de incertidumbres, la evaluación se realiza en términos probabilÃsticos utilizando técnicas de simulación numérica de Monte Carlo. Se obtienen conclusiones de interés práctico.Los autores desean expresar su agradecimiento al Ministerio de Ciencia, Innovación y Universidades de España por el apoyo financiero en el ámbito del proyecto I+D DURADOV (RTC-2015-3617-4).
