Low-temperature STM measurements combined with density functional theory 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 undercoordinated O ion by forming a new bond to an Al atom in the NiAl. The adsorption implies negative charging of the adatom. The li...

Suppose that an organization O wants to do the following: to reveal only part of its network map; to filter unwanted traffic passing through its network; and to route, to the right destination, legitimate traffic intended for hidden parts of its network. This would enable O to perform traffic filtering and routing with improved resistance against network mapping attacks. This paper proposes a p...

This paper discusses the issue of perceptions and their influence on economic processes focusing on corruption perception. The higher the perceived corruption in an organization is, the more probable it is that a person dealing with that organization would offer a bribe, thus supporting corruption. Since corruption perceptions are rarely based on actual experience, they might describe reality i...

Transient faults corrupt the content and organization of data structures. A recovery technique dealing with such faults is stabilization, which guarantees, following some number of operations on the data structure, that content of the data structure is legitimate. Another notion of fault tolerance is availability, which is the property that operations continue to be applied during the period of...

Alveolar hypoxia, a common feature of many respiratory disorders, has been previously reported to induce functional changes, particularly a decrease of transepithelial Na and fluid transport. In polarized epithelia, cytoskeleton plays a regulatory role in transcellular and paracellular transport of ions and fluid. We hypothesized that exposure to hypoxia could damage cytoskeleton organization, ...

Self-stabilization ensures automatic recovery from an arbitrary state; we define self-organization as a property of algorithms which display local attributes. More precisely, we say that an algorithm is self-organizing if (1) it converges in sublinear time and (2) reacts “fast” to topology changes. If s(n) is an upper bound on the convergence time and d(n) is an upper bound on the convergence t...
