Nd3+ (0.3 mol.%), Yb3+ (0, 1, 2, 3 and 5 mol.%): LiYF4 phosphors were grown by the Bridgman–Stockbarger technique. The luminescence intensity ratio (LIR) of (4F3/2–4I9/2, ~866 nm) emission (2F5/2–2F7/2, ~980 was taken as a parameter. energy exchange between 4F3/2 (Nd3+) 2F5/2 (Yb3+) occurs via phonons, which elucidates LIR temperature dependence. influence cross-relaxation process on sensitivit...

Abstract Some studies suggest that the dust temperatures (Td) in high-redshift (z ? 5) Lyman break galaxies (LBGs) are high. However, possible observational bias Td is yet to be understood. Thus, we perform a simple test using random realizations of LBGs with various stellar masses, temperatures, and dust-to-stellar mass ratios, examine how sample detected by ALMA biased terms Td. We show tends...

We set out to determine the ratio, qIR, of rest-frame 8–1000-μm flux, S IR, to monochromatic radio flux, S 1.4 GHz, for galaxies selected at far-infrared (IR) and radio wavelengths, to search for signs that the ratio evolves with redshift, luminosity or dust temperature, Td, and to identify any farIR-bright outliers – useful laboratories for exploring why the far-IR/radio correlation (FIRRC) is...

Post-embedding immunocytochemical techniques were used to assess distribution of gamma-aminobutyric acid (GABA) in the guinea pig cristae ampullaris. GABA-like immunoreactivity (GABA-LIR) was found in the cytoplasm of both type I (HCI) and type II hair cells (HCII), in the afferent calyx (AC) contacting HCI and some myelinated fibers in the subjacent stroma. HCI and its calyceal contacts showed...

Les théories de l’apprentissage multimédia postulent que la présence visualisations statiques ou animées améliore compréhension textes, mais seulement si les apprenants intègrent ces multiples sources d’information. Cette étude examinait l’effet du signalement par couleurs et labels pour guider génération des liens inter-repr&#...

This paper presents a novel approach to ontology localization wíth the objective of obtaining multilingual ontologies. Within the ontology development process, ontology localization has been defined as the activity of adapting an ontology to a concrete linguistic and cultural community. Depending on the ontology layers termínological and/or conceptual involved in the ontology localization activ...

We explore the relationship between gas, dust and star formation in a sample of 12 ultra-luminous infrared galaxies (ULIRGs) at high redshift compared to a similar sample of local galaxies. We present new CO observations and/or Spitzer mid-IR spectroscopy for 6 70μm-selected galaxies at z ∼ 1 in order to quantify the properties of the molecular gas reservoir, the contribution of an active galac...

INTRODUCTION The present study explored the role of resting state and personality component (BIS/BAS measure) on prefrontal cortical responsiveness to emotional cues. Indeed, we supposed that lateralized resting activity (right vs. left) and approach (BAS) versus avoidance (BIS) attitude may explain the successive emotional processing within the prefrontal cortex (PFC) based on the stimulus val...

We set out to determine the ratio, qIR, of rest-frame 8–1000-μm flux, SIR, to monochromatic radio flux, S1.4GHz, for galaxies selected at far-infrared (-IR) and radio wavelengths, to search for signs that the ratio evolves with redshift, luminosity or dust temperature, Td, and to identify any far-IR-bright outliers – useful laboratories for exploring why the far-IR/radio correlation (FIRRC) is ...
