Rab4 and cellubrevin define different early endosome populations on the pathway of transferrin receptor recycling.

During receptor mediated endocytosis, at least a fraction of recycling cargo typically accumulates in a pericentriolar cluster of tubules and vesicles. However, it is not clear if these endosomal structures are biochemically distinct from the early endosomes from which they are derived. To better characterize this pericentriolar endosome population, we determined the distribution of two endogenous proteins known to be functionally involved in receptor recycling [Rab4, cellubrevin (Cbvn)] relative to the distribution of a recycling ligand [transferrin (Tfn)] as it traversed the endocytic pathway. Shortly after internalization, Tfn entered a population of early endosomes that contained both Rab4 and Cbvn, demonstrated by triple label immunofluorescence confocal microscopy. Tfn then accumulated in the pericentriolar cluster of recycling vesicles (RVs). However, although these pericentriolar endosomes contained Cbvn, they were strikingly depleted of Rab4. The ability of internalized Tfn to reach the Rab4-negative population was not blocked by nocodazole, although the characteristic pericentriolar location of the population was not maintained in the absence of microtubules. Similarly, Rab4-positive and -negative populations remained distinct in cells treated with brefeldin A, with only Rab4-positive elements exhibiting the extended tubular morphology induced by the drug. Thus, at least with respect to Rab4 distribution, the pathway of Tfn receptor recycling consists of at least two biochemically and functionally distinct populations of endosomes, a Rab4-positive population of early endosomes to which incoming Tfn is initially delivered and a Rab4-negative population of recycling vesicles that transiently accumulates Tfn on its route back to the plasma membrane.

Development of Valpha4+ NK T cells in the early stages of embryogenesis.

The majority of T lymphocytes start to develop at around day 15 of gestation (d15)-d17 in the thymus and comprise the peripheral repertoire characterized by the expression of polymorphic T-cell antigen receptors (TCRs). Contrary to these conventional T cells, a subset of T cells, called natural killer (NK) T cells (most of them expressing an invariant TCR encoded by the Valpha14Jalpha281 gene with a 1-nt N-region), preferentially differentiates extrathymically and dominates the peripheral T-cell population at a high frequency (5% in splenic T cells and 40% in bone marrow T cells). Here, we investigated the development of NK T cells and found that the invariant Valpha14+ TCR transcripts and the circular DNA created by Valpha14 and Jalpha281 gene rearrangements can be detected in the embryo body at d9.5 of gestation and in the yolk sac and the fetal liver at d11.5-d13.5 of gestation, but not in the thymus, whereas T cells with Valpha1+ TCR expression, a major population in the thymus, were not observed at these early stages of gestation. Fluorescence-activated cell sorter analysis also demonstrated that there exist CD3+ alpha beta+ T cells, almost all of which are Valpha14/Vbeta8+ NK+ T cells, during early embryogenesis. To our knowledge, this demonstrates for the first time that a T lymphocyte subset develops in extrathymic tissues during the early stages of embryogenesis.

Applying Positive Psychology in Early Childhood.

The purpose of this paper is to introduce a framework for applying positive psychology in elementary classrooms. The target age group is children in grades K-3 (ages 5 to 8) because this age group can benefit the most from an early introduction to strategies that promote positive development (Cowne & Hightower, 1989; White, 1996). The following sections will: (a) introduce constructs of positive psychology; (b) present developmental data on how these constructs can be applied to children ages 5 to 8 years; (c) present ideas for incorporating positive psychology practice into K-3 classrooms; (d) present strategies for incorporating positive psychology with multicultural considerations; and (e) present ideas on how to implement strategies based on positive psychology that are compatible with grade level standards and sociopolitical teaching expectations.

Cap a una bibliografia musical de Màrius Torres

Com és ben sabut, en el cas del poeta lleidatà Màrius Torres (1910-1942), la relació entre la poesia i la música esdevé una vinculació essencial. Més enllà, la formació musical de Torres el va dur a musicar alguns poemes, on es barregen els trobadors medievals i els textos modernistes. Aquesta relació dual que estableix Torres amb la música ha generat al llarg dels anys una bibliografia específica que cal organitzar, definir i ampliar. Aquest article té la voluntat d’aportar un estat de la qüestió pel que fa a la bibliografia musical de Torres, no sols per les abundants referències a elements o aspectes musicals dins la seua obra, sinó també per la necessària revisió dels materials musicals manuscrits que hi conservem. Davant el projecte d’una edició de les seues obres completes, i com una mena de pas previ, el treball repassa les diferents aportacions que s’han fet des de la mort del poeta, així com les manifestacions musicals que ha generat la seua obra.

Conversion of a digital camera into a non-contact colorimeter for use in stone cultural heritage: The application case to Spanish granites

In this study, a digital CMOS camera was calibrated for use as a non-contact colorimeter for measuring the color of granite artworks. The low chroma values of the granite, which yield similar stimulation of the three color channels of the camera, proved to be the most challenging aspect of the task. The appropriate parameters for converting the device-dependent RGB color space into a device-independent color space were established. For this purpose, the color of a large number of Munsell samples (corresponding to the previously defined color gamut of granite) was measured with a digital camera and with a spectrophotometer (reference instrument). The color data were then compared using the CIELAB color formulae. The best correlations between measurements were obtained when the camera works to 10-bits and the spectrophotometric measures in SCI mode. Finally, the calibrated instrument was used successfully to measure the color of six commercial varieties of Spanish granite.

Pocas, pero contundentes palabras en la obra de Mendes da Rocha

La extensa producción arquitectónica de Mendes da Rocha resulta difícil de clasificar bajo el reduccionismo de los ‘ismos’ porque supone una revisión crítica y de síntesis de una modernidad replanteada. Se abordan tres aproximaciones al conjunto de su obra. Primera: la nueva tradición moderna de la arquitectura brasileña atendiendo a la implicación urbana de sus obras y a la escala de intervención (objeto, contexto, territorio). Segunda: la simbiosis entre arte y técnica desde una poética que tiende a la reducción de los elementos y a la simbolización de arquetipos. Tercera: la relativa al modo en que el maestro se enfrenta a las obras de intervención en el patrimonio recurriendo a una estética de la pobreza. Pocas, pero contundentes palabras: sencillez y humildad como atributos de la rotundidad.

Population synthesis of isolated neutron stars with magneto-rotational evolution – II. From radio-pulsars to magnetars

Population synthesis studies constitute a powerful method to reconstruct the birth distribution of periods and magnetic fields of the pulsar population. When this method is applied to populations in different wavelengths, it can break the degeneracy in the inferred properties of initial distributions that arises from single-band studies. In this context, we extend previous works to include X-ray thermal emitting pulsars within the same evolutionary model as radio-pulsars. We find that the cumulative distribution of the number of X-ray pulsars can be well reproduced by several models that, simultaneously, reproduce the characteristics of the radio-pulsar distribution. However, even considering the most favourable magneto-thermal evolution models with fast field decay, lognormal distributions of the initial magnetic field overpredict the number of visible sources with periods longer than 12 s. We then show that the problem can be solved with different distributions of magnetic field, such as a truncated lognormal distribution, or a binormal distribution with two distinct populations. We use the observational lack of isolated neutron stars (NSs) with spin periods P > 12 s to establish an upper limit to the fraction of magnetars born with B > 1015 G (less than 1 per cent). As future detections keep increasing the magnetar and high-B pulsar statistics, our approach can be used to establish a severe constraint on the maximum magnetic field at birth of NSs.

Phrase-based statistical machine translation: explanation of its processes and statistical models and evaluation of the English to Spanish translations produced

Statistical machine translation (SMT) is an approach to Machine Translation (MT) that uses statistical models whose parameter estimation is based on the analysis of existing human translations (contained in bilingual corpora). From a translation student’s standpoint, this dissertation aims to explain how a phrase-based SMT system works, to determine the role of the statistical models it uses in the translation process and to assess the quality of the translations provided that system is trained with in-domain goodquality corpora. To that end, a phrase-based SMT system based on Moses has been trained and subsequently used for the English to Spanish translation of two texts related in topic to the training data. Finally, the quality of this output texts produced by the system has been assessed through a quantitative evaluation carried out with three different automatic evaluation measures and a qualitative evaluation based on the Multidimensional Quality Metrics (MQM).
