The dynamics of soil moisture and temperature states are forced by land surface fluxes that form the coupling between the soil and the atmosphere. This twoway interaction between the soil and the atmosphere results in feedback mechanisms that affect the temporal patterns of variability of the system. To understand these characteristics of soil moisture and temperature variability, a one-dimensi...

Les références principales pour l’interprétation du produit de mélange de deux séries en termes d’automates et les applications aux identités syntaxiques sont [Lo 2002] 1.3 et [J 1980]. Dans le cours du 14 mars les exemples suivant sont traités: 1. Mélange de deux éléments de K < X > 2. L’identité x∗0x(x1 · · ·xn) = x∗0x1x∗0x2 · · ·x∗0xnx∗0 3. L’identité (x0 + x1)∗ = x∗0xx∗1 4. L’identité (1 + ...

RÉSUMÉ. L’idée à l’origine du modèle de mélange conjoint (MMConjoint) est de classer simultanément deux ensembles d’observations en introduisant un a priori conjoint entre les deux classifications et un lien statistique entre les deux observations. Nous étudions en particulier le cas de mélanges gaussiens et le cas de mélanges paramétriques non gaussiens construits à partir de copules et de mar...

We consider the mixing behaviour of the solutions of the continuity equation associated with a divergence-free velocity field. In this announcement we sketch two explicit examples of exponential decay of the mixing scale of the solution, in case of Sobolev velocity fields, thus showing the optimality of known lower bounds. We also describe how to use such examples to construct solutions to the ...

The location of the suture zone between South China Block (SCB) and Indochina (IB) is disputed. Recently, along Song Chay (Chay river) belt, a mélange was proposed as potential SCB IB. However, provenance age poorly known. In order to better constrain elements forming mélange, nine samples detrital material, one orthogneiss were subjected zircon U-Pb Hf isotope analysis. Detrital zircons from s...

[1] The small footprint ( 70 m) and 172 m alongtrack spacing of the Geoscience Laser Altimeter System (GLAS) on the Ice, Cloud and land Elevation Satellite (ICESat) provides unprecedented horizontal resolution for a satellite altimeter. This enables ICESat to map many previously unresolved features on ice shelves, such as crevasses, rifts, grounding zones and ice fronts. We present examples of ...

bibi maryam granitoid body with about 5 km2 has intruded into ophiolite mélange complex in sistan suture zone, in east of iran. thermal effects of this body on the host rocks show that this activity occurred after emplacement of ophiolite mélange. this intrusive body with general northwest – southeast trend is mainly tonalite-quartz diorite but there is a minor unit as dykes of granodiorite in ...

baft ophiolite mélange is a part of naein-baft ophiolite (southeast of kerman province in iran). serpentinites from baft ophiolite mélange contain different types of spinels such as chromite, chromespinel, ferritchromite and magnetite which can reveal different stages of evolution in host serpentinites. the compositions of baft chromites show that they belong to podiform chromitites that may ha...
