This article centers on an NGO-induced fog-capture project in Lima, Peru. While presented by the NGO as alternative water-supply system for residents lacking state infrastructure, fog catchers ultimately failed to live up promises about potable water. Yet turned into a material impossibility, project’s failure yielded series of new possibilities and expectations, instance potential acquisition ...

The use of Beneficial Microorganisms for Corals (BMCs) has been proposed recently as a tool the improvement coral health, with knowledge in this research topic advancing rapidly. BMCs are defined consortia microorganisms that contribute to health through mechanisms include ( a) promoting nutrition and growth, b) mitigating stress impacts toxic compounds, c) deterring pathogens, d) benefiting ea...

In the distributed Deutsch-Jozsa promise problem, two parties are to determine whether their respective strings x, y ∈ {0, 1}n are at the Hamming distance H(x, y) = 0 or H(x, y) = n2 . Buhrman et al. (STOC’ 98) proved that the exact quantum communication complexity of this problem is O(logn) while the deterministic communication complexity is Ω(n). This was the first impressively (exponential) ...

Fault detection is a crucial issue in autonomic networks for identifying unreliable nodes and reducing their impact on the network availability and performance. We propose in this paper to improve this situation based on the concept of promised cooperation. We exploit the promise theory framework to model voluntary cooperation among network nodes and make them capable of expressing the trust in...

We study the communication complexity of linear algebraic problems over finite fields in the multiplayer message passing model, proving a number of tight lower bounds. Specifically, for a matrix which is distributed among a number of players, we consider the problem of determining its rank, of computing entries in its inverse, and of solving linear equations. We also consider related problems s...
