Localization of antigens PwA33 and La on lampbrush chromosomes and on nucleoplasmic structures in the oocyte of the urodele Pleurodeles waltl: Light …

1994

Monoclonal antibodies A33/22 and La11G7 have been used to study the distribution of the corre-sponding antigens, PwA33 and La, on the lampbrush chromosome loops and nucleoplasmic structures of P. waltl oocytes, using immunofluorescence, confocal laser scanning microscopy and immunogold labeling. The results obtained with these antibodies have been compared with those obtained with the Sm-antigen-specific monoclonal antibody Y12. All these monoclonal antibodies (mAbs) labeled the matrices of the majority of normal loops along their whole length. Nucleoplasmic RNP granules showed a strong staining with the mAbs La11G7 and Y12 throughout their mass, but with the mAb A33/22, they showed only a …

A simple algorithm to estimate evapotranspiration from DAIS data: Application to the DAISEX campaigns

2005

DOI:10.1016/j.jhydrol.2005.03.027; The knowledge of evapotranspiration is of great interest in many applications such as assessing irrigation water use. In this paper, a methodology is presented to estimate evapotranspiration using the surface energy balance model S-SEBI (Simplified Surface Energy Balance Index) and the evaporative fraction. The method is applicable under the assumptions of constant atmospheric conditions and sufficient wet and dry pixels over the image. The model uses remotely sensed parameters such as albedo, MSAVI (Modified Soil Adjusted Vegetation Index) and surface temperature and emissivity images. The methodology has been applied over the Barrax test site, located in…

From Europe to Africa and vice versa: evidence for multiple intercontinental dispersal in ribbed salamanders (Genus Pleurodeles)

2004

Aim  The intricate puzzle-like geography of the western Mediterranean is a product of long-term tectonic and orogenic events, supplemented by repeated climatic oscillations since the Pliocene. It offers numerous vicariance events that may be invoked to explain speciation in amphibians. We test for plausibility of two mutually exclusive Iberian–African vicariance hypotheses to explain the basal split within newts of the genus Pleurodeles: (1) the disconnection of the Betic arch c. 14 Ma and (2) the end of the Messinian salinity crisis 5.33 Ma. Location  Specimens of P. waltl and P. poireti were sampled from 32 populations in Portugal, Spain, Morocco, Algeria and Tunisia. Methods  Parts of th…

Rateless Codes Performance Analysis in Correlated Channel Model for GEO Free Space Optics Downlinks

2012

Settore ING-INF/03 - TelecomunicazioniFree Space Optics (FSO) technologies for satellite communications offer several advantages: wide bandwidth high rate capability immunity to electromagnetic interference and small equipment size. Thus they are suitable for inter-satellite links deep space communications and also for high data rate ground-to-satellite/satellite-to-ground communications. Nevertheless FSO links suffer impairments that cause power signal degradation at the receiver. Scattering and absorption cause power signal attenuations predictable by suitable deterministic models. Optical turbulence causes random irradiance fluctuations which can generate signal fading events and can thereby only be predicted by statistical models. Attenuation and fading events can corrupt FSO links and so it would be recommended to add mitigation error codes on the communication link. FSO channel can be described as an erasure channel: fading events can cause erasure errors. We have identified in rateless codes (RCs) a suitable solution to be employed in FSO links. RCs do not need feedback and they add a redundant coding on the source data that allows the receiver to recover the whole payload despite erasure errors. We implemented two different of rateless codes: Luby Transform (LT) and Raptor. We analyzed their performances on a simulated turbulent GEO FSO downlink (1 Gbps - OOK modulation) at a 106 μm wavelength and for different values of zenith angles. Assuming a plane-wave propagation and employing Hufnagel-Valley we modeled the downlink using: 1) a temporal correlated channel model based on Gamma-Gamma probability distribution and 2) an irradiance covariance function that we converted on a time function using Taylor frozen eddies hypothesis. Our new channel model is able to simulate irradiance fluctuations at different turbulence conditions as it will be shown in the full paper. We will also report performance results of LT and Raptor codes at overhead range varying between 0 and 50% and for different values of source packets.Settore ING-INF/01 - Elettronica

CASO CLINICO: L’UTILIZZO DELL’ORMONE DELLA CRESCITA IN SOGGETTO CON SINDROME DA MICRODELEZIONE E SBILANCIAMENTO CROMOSOMICO (CR3-6)

2019

PRESENTAZIONE DEL CASO, STORIA CLINICA E SINTOMATOLOGIA. Descriviamo il caso di una bambina di 8 anni giunta alla nostra osservazione per scarso accrescimento all’età di 4 anni (statura<3DS). Nata pretermine (EG:35+3) con parto spontaneo, SGA. Distress respiratorio alla nascita per cui è stata ricoverata in UTIN per la prima settimana di vita. Parametri auxologici alla nascita: PN: 1600gr (-1,94DS), lunghezza 39cm (-2,72DS), cc 28cm (-2,65DS). Presentava inoltre note dismorfiche al volto, schisi del palato molle, piede talo valgo bilaterale e ritardo neuromotorio. Dato il quadro sindromico si eseguivano dopo poche settimane dalla nascita indagini genetiche; all’array CGH si evidenziava d…

Design e narrazioni

2022

Il testo nasce dall’esigenza di mettere a fuoco le implicazioni cognitive, metodologiche e progettuali del concetto di narrazione, sempre più ricorrente nella nostra esperienza quotidiana soprattutto per le molteplici forme di comunicazione e di produzioni culturali che vi si ispirano; si tratta di un concetto che anche nella riflessione teorica e nella progettualità del design sta alimentando dimensioni fortemente innovative ed evolutive nella costruzione, comunicazione di significati, contenuti immateriali, esperienze e valori emozionali che si sovrappongono e s’intrecciano all’espressione tangibile e funzionale degli oggetti, degli artefatti comunicativi, degli spazi. Si propone un perco…

The text arises from the need to focus on the cognitive methodological and design implications of the concept of storytelling increasingly recurrent in our daily experience especially for the many forms of communication and cultural productions that are inspired by itSettore ICAR/13 - Disegno Industrialeit is a concept that also in theoretical reflection and design planning is feeding strongly innovative and evolutionary dimensions in the construction communication of meanings intangible content experiences and emotional values that overlap and intertwine with the tangible and functional expression of objects communicative artifacts spaces.. It proposes a cognitive path tangent to the development of "narratology" and the theories of narrationthus we come across a multiplicity of disciplinary connections affecting sociology psychology anthropology philosophy semiotics and of course history cinema journalism advertising up to corporate communication and political propaganda. It is an articulated panorama that today seems to expand more and more and far from being mainly addressed to theoretical issues increasingly seems to be modeled on application performative and design aspects.

Dynamiques de populations en milieu hétérogène : modèles et estimation de paramètres

2017

Prod 2017-344i SPE équipe EA GESTAD INRA; National audience; Cet exposé traite de (i) la modélisation de dynamiques de populations dans des paysages hétérogènes, (ii) la modélisation des paysages eux-mêmes, (iii) l'estimation des paramètres de ces modèles à partir de données d'abondance ou de données génétiques. Nous nous concentrerons sur deux grandes classes de modèles de dynamique des populations : les modèles individu-centrés basés sur des équations différentielles stochastiques, et les modèles de réaction-diffusion. Après une introduction du lien entre ces approches, 5 illustrations issues des projets sont présentées: - modélisation de paysages hétérogènes fragmentés, via l’outil MULTI…
