Low-temperature STM measurements combined with DFT calculations are employed to study the adsorption of gold on alumina/NiAl(110). The binding of Au monomers involves breaking of an oxide Al-O bond below the adatom and stabilizing the hence under-coordinated O ion by forming a new bond to an Al atom in the NiAl. The adsorption implies negative charging of the adatom. The linear arrangement of f...

This paper describes the application of an Organization-based Multiagent System Engineering (O-MaSE) compliant process to the development of a holonic multiagent system (MAS) for testing control algorithms for an intelligent power distribution system. The paper describes the Adaptive O-MaSE (AO-MaSE) process, which provides architects and developers a structured approach for testing and iterati...

The emerging paradigm, by contrast, recognizes that the collective and holistic properties of physical systems can display new and unforeseen modes o f behaviour that are not captured by the Newtonian and thermodynamic approaches. There arises the possibility of self-organization in which systems suddenly leap into more elaborate forms. These forms are characterized by greater complexity, by co...

Highly aligned one-dimensional (1D) nanorods of the transparent conducting oxide In(2)O(3) have been grown on (110)-oriented Y-stabilized ZrO(2) substrates, whereas growth on (100) and (111) substrates leads respectively to blocklike 3D islands and continuous films. It is shown that the striking influence of substrate orientation on the growth morphology is controlled by differences in energies...

Several algorithms for parallel disk systems have appeared in the literature recently and they are asymptotically optimal in terms of the number of disk accesses Scalable systems with parallel disks must be able to run these algorithms We present for the rst time a list of capabilities that must be provided by the system to support these optimal algorithms control over declustering querying abo...

We deal with dynamic information organization for more efficient Internet browsing. As the appropriate algorithm for this purpose, we propose modified ART (artificial resonance theory) algorithm, which functions similarly with the dynamic Star-clustering algorithm but performs a more efficient time complexity of O(nk), (k << n) instead of O(n2log2n) found in the dynamic Star-clustering algorith...

The paper o¤ers a new theoretical framework to investigate the organization of technology transfer between universities and industry. We ...nd that technology transfer o¢ces (TTOs) can reduce the uncertainty and adverse selection problems between faculty-inventors and industrial ...rms, and thus play a crucial role in forming the market for university inventions. Our results help explain the si...

Although potentially powerful, molecular oxygen is an inert oxidant due to the triplet nature of its ground state. Therefore, many enzymesse various metal cations (M) to produce singlet active species M(n) O(2) . In this communication we investigate the topology of the Electron Localization Function (ELF) within five biomimetic complexes which are representative of the strategies followed by me...

The organization of lipids and proteins into domains in cell membranes is currently an established subject within biomembrane research. Fluorescent probes have been used to detect and characterize these membrane lateral heterogeneities. However, a comprehensive understanding of the link between the probes' fluorescence features and membrane lateral organization can only be achieved if their pho...
