Combination of DROOL rules and Protégé knowledge bases in the ONTO-H annotation tool
ONTO-H is a semi-automatic collaborative tool for the semantic annotation of documents, built as a Protégé 3.0 tab plug-in. Among its multiple functionalities aimed at easing the document annotation process, ONTO-H uses a rule-based system to create cascading annotations out from a single drag and drop operation from a part of a document into an already existing concept or instance of the domain ontology being used for annotation. It also gives support to the detection of name conflicts and instance duplications in the creation of the annotations. The rule system runs on top of the open source rule engine DROOLS and is connected to the domain ontology used for annotation by means of an ad-hoc programmed Java proxy
Identification of descendants of an extinct bovine population from the Algarve region of Portugal using numerical taxonomy analysis of morphological traits
The morphology of a sample of four bulls and 43 cows, presumed to be
descendants of the extinct cattle breed âAlgarviaâ (AG), was used to
assign their relationship with animals from other Portuguese autochthonous
breeds â Arouquesa (AR), BarrosaË (BA), Cachena (CA), Marinhoa
(MA), Maronesa (MO), Minhota (MN), Mirandesa (MI), (only bulls),
Alentejana (AL), Garvonesa (GA), Mertolenga (ME) and Preta (PR).
Standard numerical taxonomic methods were applied to a set of 183
(cows) and 170 (bulls) traits, to derive average pairwise taxonomic distances
among the sample of 257 cows and 76 bulls. Distance coefficients
(morphological index of distance) ranged from 0.22 to 2.62 (cows) and
from 0.49 to 2.13 (bulls). Unweighted pair group method using arithmetic
averages (UPGMA)-based phenograms and a principal coordinate
analysis showed that bulls were highly clustered and cows showed a
tendency to cluster according to their geographical and breed origin.
The AG population grouped together with GA, AL, ME and MN breeds
in the Red Convex group. The average taxonomic distance among
breeds was 1.02, the highest being 1.39 (ME versus BA) and the lowest
being 0.64 (MA versus AR). The approach allowed for the identification
of a phenotypically differentiated set of animals, comprising 19 cows
and four bulls representative of the AG breed, and which can be targeted
in further studies aiming at the recovery of this extinct breed

Dishonest signals of strength in male slender crayfish (Cherax dispar) during agonistic encounters
Many animals resolve disputes without combat by displaying signals of potential strength during threatening displays. Presumably, competitors use each other's displays to assess their relative strengths, and current theory predicts that these signals of strength should generally be honest. We tested this prediction by investigating the relationships among morphology, performance, and social dom inance in males of the slender crayfish Cherax dispar. Crayfish routinely use their enlarged front claws (chelae) for both intimidation and fighting, making this species ideal for studying the honesty of weapon size. We evaluated five competing models relating morphological and physiological traits to dominance during paired competitive bouts. Based on the best model, larger chelae clearly resulted in greater dominance; however, chela strength had no bearing on dominance. Thus, displays of chela size were dishonest signals of strength, and the enlarged chelae of males seemingly function more for intimidation than for fighting. In addition, an analysis of the performance of isolated chela muscle showed that muscle from male crayfish produced only half the force that muscle from female crayfish produced (236.6 +/- 26.4 vs. 459.5 +/- 71.6 kN m(-2)), suggesting that males invest more in developing larger chelae than they do in producing high-quality chela muscle. From our studies of crayfish, we believe dishonest signaling could play a greater role in territorial disputes than previously imagined
Nuevas aplicaciones de la cĂĄpsula endoscĂłpica: PILLCAMâą ESO
ABSTRACT
Capsule endoscopy has opened a new era in
small bowel examination. Its indications are now welldefined
and currently, wireless capsule endoscopy is
considered as the first-line imaging tool for the
diagnosis of small bowel diseases. ECE has been
shown to be feasible, safe and a good alternative
technique in patients refusing conventional
endoscopy. Although results reported in both GERD
and cirrhotic patients are encouraging, great
differences in terms of accuracy (particularly in GERD
patients) have been found in published studies. These
differences have been attributed to study designs, the
lack of adequate experience and inconvenience of
ingestion protocols. In summary, more large-scale
studies evaluating the new 14-fps capsule, adequate
ECE-experience and new modified ingestion protocols
are still needed
Extension of geographical distribution of three common species of diurnal butterflies (Lepidoptera: Papilionoidea) from the Colombian Caribbean
En este documento se registran tres especies comunes de mariposas diurnas de la regiĂłn Caribe colombiana (Aides dysoni, Calpodes ethlius y Anteos clorinde). Los especĂmenes fueron capturados con red entomolĂłgica en muestreos realizados en el municipio de Arjona (departamento de BolĂvar) en el año de 2015 entre las 8:00 y 16:00 horas. Para cada una de ellas se proporcionan caracteres morfolĂłgicos Ăștiles para su reconocimiento y se complementa su distribuciĂłn en el NeotrĂłpico.In this document we extend the geographical distribution for three common species of diurnal butterflies from the Colombian Caribbean region (Aides dysoni, Calpodes ethlius, and Anteos clorinde). The specimens were captured with an insect net in samplings conducted in the Arjona jurisdiction (Bolivar, Deparment) in 2015, between 8:00 and 16:00 hours. For each of them we provide important morphological characters for their recognition, and complement their distribution in the Neotropic
Serum selenium concentrations and diabetes in U.S. adults : National Health and Nutrition Examination Survey (NHANES) 2003â2004
Background: Increasing evidence suggests that high selenium levels are associated with diabetes and other cardiometabolic risk factors.
Objectives: We evaluated the association of serum selenium concentrations with fasting plasma glucose, glycosylated hemoglobin levels, and diabetes in the most recently available representative sample of the U.S. population.
Methods: We used a cross-sectional analysis of 917 adults â„ 40 years of age who had a fasting morning blood sample in the National Health and Nutrition Examination Survey 2003â2004. We evaluated the association of serum selenium, measured by inductively coupled plasma-dynamic reaction cell-mass spectrometry, and diabetes, defined as a self-report of current use of hypoglycemic agents or insulin or as fasting plasma glucose â„ 126 mg/dL.
Results: Mean serum selenium was 137.1 ÎŒg/L. The multivariable adjusted odds ratio [95% confidence interval (CI)] for diabetes comparing the highest quartile of serum selenium (â„ 147 ÎŒg/L) with the lowest (< 124 ÎŒg/L) was 7.64 (3.34â17.46). The corresponding average differences (95% CI) in fasting plasma glucose and glycosylated hemoglobin were 9.5 mg/dL (3.4â15.6 mg/dL) and 0.30% (0.14â0.46%), respectively. In spline regression models, the prevalence of diabetes as well as glucose and glycosylated hemoglobin levels increased with increasing selenium concentrations up to 160 ÎŒg/L.
Conclusions: In U.S. adults, high serum selenium concentrations were associated with higher prevalence of diabetes and higher fasting plasma glucose and glycosylated hemoglobin levels. Given high selenium intake in the U.S. population, further research is needed to determine the role of excess selenium levels in the development or the progression of diabetes
Searches for neutrino counterparts of gravitational waves from the LIGO/Virgo third observing run with KM3NeT
The KM3NeT neutrino telescope is currently being deployed at two different sites
in the Mediterranean Sea. First searches for astrophysical neutrinos have been performed using
data taken with the partial detector configuration already in operation. The paper presents
the results of two independent searches for neutrinos from compact binary mergers detected
during the third observing run of the LIGO and Virgo gravitational wave interferometers.
The first search looks for a global increase in the detector counting rates that could be
associated with inverse beta decay events generated by MeV-scale electron anti-neutrinos.
The second one focuses on upgoing track-like events mainly induced by muon (anti-)neutrinos
in the GeVâTeV energy range. Both searches yield no significant excess for the sources in the
gravitational wave catalogs. For each source, upper limits on the neutrino flux and on the
total energy emitted in neutrinos in the respective energy ranges have been set. Stacking
analyses of binary black hole mergers and neutron star-black hole mergers have also been
performed to constrain the characteristic neutrino emission from these categories.Grants PID2021-124591NB-C41, -C42, -C43 funded by MCIN/AEI/10.13039/501100011033 and, as appropriate, by âERDF A way of making Europeâ, by the âEuropean Unionâ or by the âEuropean Union NextGenerationEU/PRTRâPrograma de Planes Complementarios I+D+I (refs.
