Grid operators in EGEE use a dedicated dashboard as their central operational tool, stable and scalable for the last 5 years despite continuous upgrade from specifications by users, monitoring tools or data providers. In EGEE-III, regionalisation of operations led the tool developers to conceive a standalone instance of this tool. Hereby, we will present the concept and the EELA-II implementati...

ion is followed by addition of a deuterium atom to the alkyl radical These stepsare shownschematically inFigure5. Because the flux of deuterium atoms is essentially constant, the overall reaction is assumed to be first order in the concentration of C-H bonds. Also, because reaction 2 is the addition of two radicals, it is assumed to occur rapidly; thus, reaction 1 is the rate-limiting step. Wit...

The “Standard Model” of elementary particle physics encompasses the progress that has been made in the past half-century in understanding the weak, electromagnetic, and strong interactions. The name was apparently bestowed by my Ph. D. thesis advisor, Sam B. Treiman, whose dedication to particle physics kindled the light for so many of his students during those times of experimental and theoret...

We studied the formation and stability of Stearic Acid (SA) based films on aqueous sub-phases via Langmuir trough and imaging ellipsometry experiments. The aqueous phase was based on Artificial Sea Water (ASW), a multicomponent salt solution with a total molarity of 0.53. The composition of this 10 solution was varied via dilution (1, 10 and 100 times) and adjustment of the pH (3, 7, 10). Also ...

In this article we address the problem of realizing a service-providing reasoning infrastructure for pro-active human assistance in intelligent environments. We propose SAM, an architecture which leverages temporal knowledge represented as relations in Allen’s interval algebra and constraint-based temporal planning techniques. SAM provides two key capabilities for contextualized service provisi...

Resistive-type palladium structures for hydrogen sensing remains as a research focus for their simplicity in device construction. We demonstrate that a siloxane self-assembled monolayer placed between a substrate and an evaporated ultrathin Pd film promotes the formation of small Pd nanoclusters and reduces the stiction between the palladium and the substrate. The resulting Pd nanocluster film ...

MOTIVATION Identifying differentially regulated genes in experiments comparing two experimental conditions is often a key step in the microarray data analysis process. Many different approaches and methodological developments have been put forward, yet the question remains open. RESULTS Varmixt is a powerful and efficient novel methodology for this task. It is based on a flexible and realisti...

Charge transport characteristics for metal–molecule–metal junctions containing two structurally related -conjugated systems were studied to probe – interactions in molecular junctions. The first molecule contains a typical -conjugated framework derived from phenylene vinylene units, whereas the second has the phenylene vinylene structure interrupted by a [2.2]paracyclophane (pCp) core. Electroc...

Two-phase monolayers adsorbed on crystalline substrates can form many patterns. After reviewing the experimentally observed patterns on various substrates, we extend a thermodynamic theory to account for the anisotropy in surface stress, substrate sti4ness, and phase boundary energy. We solve the elastic 6eld in the anisotropic substrate by using the Stroh formalism. We then focus on the patter...

We report here the spectra that result when singly and doubly charged buckminsterfullerene ions, C& and C g , collide with self-assembled monolayer films at collison energies ranging from 125 to 320 eV. The surfaces were prepared by the spontaneous assembly of octadecanethiol (CH3(CHz),7SH), perdeuteroeicosanethiol (CD,(CDz),$H), and 2-(perfluorooctyl)-ethanethiol (CF3(CFd7CH2CHZSH) on vapor-de...
