Distributed storage systems introduce redundancy to increase reliability. When erasure coding is used, the exact repair problem arises: if a node storing encoded information fails, in order to maintain the same level of reliability we need to create encoded information at a new node. This amounts to a partial recovery of the code, whereas conventional erasure coding focuses on the complete reco...

Solar devices based on semiconductor nanoparticles require the use of conductive ligands; however, replacing the native, insulating ligands with conductive metal chalcogenide complexes introduces structural defects within the crystalline nanostructure that act as traps for charge carriers. We utilized atomically thin semiconductor nanoplatelets as a convenient platform for studying, both micros...

Automatically discovering semantic relations between ontologies is an important task with respect to overcoming semantic heterogeneity on the semantic web. Existing ontology matching systems, however, often produce erroneous mappings. In this paper, we address the problem of errors in mappings by proposing a completely automatic debugging method for ontology mappings. The method uses logical re...

Purpose This study aims to identify the responses required repair political trust in Tunisia and differences between two key stakeholder groups, namely, politicians voters. Design/methodology/approach A sequential mixed method was adopted using data sources: semi-structured interviews conducted with citizens politicians; media from TV talk shows. Data collected over a three-year period followin...

We consider theories characterized by a set of Ward operators which do not form a closed algebra. We impose the Slavnov–Taylor identity built out of the Ward operators and we derive the acceptable breaking of the algebra and the general form of the classical action. The 1PI generating functional is expressed in terms of the known quantities characterizing the theory and of a nontrivial integrab...

Aquiet revolution has been going on in town planning and architectural circles over the last decade. Established zoning and urban design ideas are being questioned and reversed. Urban planners and designers are reviving and reinterpreting ideas that prevailed before the automobile spread our cities apart and hollowed out their cores, before mass transit became the transportation mode for an und...
