SMOS-IC: An Alternative SMOS Soil Moisture and Vegetation Optical Depth Product
2017
© 2017 by the authors. The main goal of the Soil Moisture and Ocean Salinity (SMOS) mission over land surfaces is the production of global maps of soil moisture (SM) and vegetation optical depth (τ) based on multi-angular brightness temperature (TB) measurements at L-band. The operational SMOS Level 2 and Level 3 soil moisture algorithms account for different surface effects, such as vegetation opacity and soil roughness at 4 km resolution, in order to produce global retrievals of SM and τ. In this study, we present an alternative SMOS product that was developed by INRA (Institut National de la Recherche Agronomique) and CESBIO (Centre d'Etudes Spatiales de la BIOsphère). One of the main go…
Iespēju vienlīdzība un ekonomikas izaugsme: gadījumu izpēte Eiropā
2021
Attīstoties filozofijai, sociālo zinātņu teorijai un ekonomikai, rezultātu vienlīdzību nomainīja iespēju vienlīdzība uzmanības centrā. Kaut arī Kuzņeca līkne nav dzelzs likums, nav pintes, lai to pārbaudītu, tā tomēr mums dod zināmu informāciju, kura atspoguļo to, cik " veselīga " ir mūsu attīstība. Šī maģistra darba mērķis ir izpētīt ekonomiskās izaugsmes ietekmi no iespēju egalitārisma viedokļa. Šī darba galvenā hipotēze ir sekojoša: “Ekonomiskā izaugsme nelabvēlīgi ietekmē iespēju vienlīdzību attīstītajās valstīs noteiktā periodā.” Runājot par iespēju vienlīdzības novērtējumu, šajā rakstā ir izmantots Iespēju indeksa modelis. IKP uz vienu iedzīvotāju tiek uzskatīts par mainīgo, lai ats…

Ethnic segregation in a metropolitan area of Italy: the case of Palermo
2015
La segregazione residenziale etnica in Italia è una questione emergente, che sarà fondamentale nella definizione e attuazione di politiche urbanistiche e sociali. Questo articolo si focalizza sull’analisi del fenomeno nel comune di Palermo. Utilizziamo i dati della popolazione residente in città nel 2011 in tutti i quartieri suddivisa per etnia. Facciamo dapprima ricorso a tecniche di analisi spaziale tradizionale al fine di descrivere la segregazione residenziale degli stranieri e, tra le altre misure, calcoliamo l'indice di dissimilarità di Duncan e Duncan. Successivamente, applichiamo un approccio metodologico recentemente proposto in letteratura che consente di correggere la distorsione…
La motivación de compra de productos de comercio justo: propuesta de un índice de medición por diferencias sociodemográficas
2012
Entre los diferentes campos de estudio del comercio justo, el basado en el análisis de las características del consumidor es de los más ricos e interesantes. El objetivo del texto es contribuir a dar respuesta a la pregunta sobre las motivaciones que llevan a los consumidores a comprar productos de comercio justo. Para ello, se analizan el concepto de comercio justo y la dimensionali-dad de las motivaciones de compra de este tipo de producto. El trabajo explora empíricamente las diferencias socio-demográficas entre los consumidores en-cuestados, sobre la base de un índice construido a partir de las puntuaciones de la motivación de compra en tiendas de comercio justo. Dicho índice permite de…

A Curvature Based Method for Blind Mesh Visual Quality Assessment Using a General Regression Neural Network
2016
International audience; No-reference quality assessment is a challenging issue due to the non-existence of any information related to the reference and the unknown distortion type. The main goal is to design a computational method to objectively predict the human perceived quality of a distorted mesh and deal with the practical situation when the reference is not available. In this work, we design a no reference method that relies on the general regression neural network (GRNN). Our network is trained using the mean curvature which is an important perceptual feature representing the visual aspect of a 3D mesh. Relatively to the human subjective scores, the trained network successfully asses…
Central limit theorem for bifurcating Markov chains under L 2 -ergodic conditions
2021
Bifurcating Markov chains (BMC) are Markov chains indexed by a full binary tree representing the evolution of a trait along a population where each individual has two children. We provide a central limit theorem for additive functionals of BMC under L 2-ergodic conditions with three different regimes. This completes the pointwise approach developed in a previous work. As application, we study the elementary case of symmetric bifurcating autoregressive process, which justify the non-trivial hypothesis considered on the kernel transition of the BMC. We illustrate in this example the phase transition observed in the fluctuations.
Gas chromatographic and mass spectrometric characterization of the organic acids extracted from some preparations containing lyophilized royal jelly.
2009
Thirty-five aliphatic acids were identified by gas chromatography-mass spectrometry from the ether extract of commercial preparations containing lyophilized royal jelly. The article presents linear-programmed retention indices on capillary columns with non-polar and low-polar stationary phases and mass spectra for identified compounds which were not characterized earlier by these parameters. Nine compounds are reported for the first time as royal jelly constituents.
High‐resolution histographical mapping of glucose concentrations in developing cotyledons of Vicia faba in relation to mitotic activity and storage p…
1998
Summary Previous studies provided evidence that the carbohydrate status triggers developmental processes in the growing cotyledons ofVicia faba. We describe here the high-resolution mapping of glucose concentrations in tissue sections of developing faba bean cotyledons by quantitative bioluminescence and single-photon imaging. Patterns of local glucose distributions are compared with tissue cell type, mitotic index and the distribution pattern of starch. During cotyledon differentiation, gradients in the glucose concentration emerge which are related to the particular cell type. Higher concentrations are found in non-differentiated premature regions of the cotyledon whereas mature starch-ac…
