The modelling of concurrent systems by synchronized distributed automata generates a natural independence notion between events of the global system. The theory of Mazurkiewicz traces suggests that such an independence relation induces an equivalence relation over the sequences of events of the system. So-called Partial-Order Automata use independence for the reductions of the interleaved globa...

The United Nations Environment Programme (UNEP) has been focusing on actions with regard to lead and cadmium since 2001 when the work of the Partnership for Clean Fuels and Vehicles (PCFV) was initiated. The development and finalization of the reviews of scientific information on lead and cadmium facilitated discussions among Governments in relation to the need for global action with regard to ...

This paper studies a fundamental relation that exists between stabilizability assumptions usually employed in distributed model predictive control implementations, and the corresponding notions of invariance implicit in such controllers. The relation is made explicit in the form of a theorem that presents sufficient conditions for global stabilizability. It is shown that constraint admissibilit...

A concept (or Galois) lattice is built on a binary relation; this relation can be represented by a bipartite graph. We explain how we can use the graph tool of clique minimal separator decomposition to decompose some bipartite graphs into subgraphs in linear time; each subgraph corresponds to a subrelation. We show that the lattices of these subrelations easily yield the lattice of the global r...

In the centralized context, global constraints have been essential for the advancement of constraint reasoning. In this paper we propose to include soft global constraints in distributed constraint optimization problems (DCOPs). Looking for efficiency, we study possible decompositions of global constraints, including the use of extra variables. We extend the distributed search algorithm BnB-ADO...

Strategic management of global information systems (IS) is increasingly important for the multinational investment banking industry that had originally utilized information networks crossing national borders for profit making purposes. Significant changes have occurred to the scope of strategic management of IS in modern organizations following major restructuring of the global business environ...

Most of the previous works on relation extraction between named entities are often limited to extracting the pre-defined types; which are inefficient for massive unlabeled text data. Recently; with the appearance of various distributional word representations; unsupervised methods for many natural language processing (NLP) tasks have been widely researched. In this paper; we focus on a new find...

While the relation between systolic blood pressure (SBP) and vascular events is linear down to the high-normal range, the relation between SBP and cognition is less clear. We cross-sectionally assessed the relation between SBP and cognition in a cohort extending from mid- to late-life. From a total of 2200 community-dwelling individuals we recruited 377 aged 44 to 82 years (median: 64 years, 17...

Most existing relation extraction models make predictions for each entity pair locally and individually, while ignoring implicit global clues available in the knowledge base, sometimes leading to conflicts among local predictions from different entity pairs. In this paper, we propose a joint inference framework that utilizes these global clues to resolve disagreements among local predictions. W...
