A dynamic spatio-temporal model to investigate the effect of movements of animals on the spreading of Bluetongue BTV-8 in Belgium Hasselt University
When Bluetongue Virus Serotype 8 (BTV-8) was first detected in Northern Europe in 2006, several guidelines were immediately put into place with the goal to protect farms and stop the spreading of the disease. This however did not prevent further rapid spread of BTV-8 across Northern Europe, which has resulted to substantial economic losses, particularly in the sheep and cattle industry (Wilson and Mellor, 2009). A better understanding of the ...
Computational Nature of Gene Assembly in Ciliates Hasselt University
Ciliates are a very diverse and ancient group of unicellular eukaryotic organisms. A feature that is essentially unique to ciliates is the nuclear dualism, meaning that they have two functionally different types of nuclei, the macronucleus and the micronucleus. During sexual reproduction a micronucleus is transformed into a macronucleus – this process is called gene assembly, and it is the most involved naturally occurring example of DNA ...
On the CRON Conjecture Hasselt University
Declarative networking is a recent approach to programming distributed applications with languages inspired by Datalog. A recent conjecture posits that the delivery of messages should respect causality if and only if they are used in non-monotone derivations. We present our results about this conjecture in the context of Dedalus, a Datalog-variant for distributed programming. We show that both directions of the conjecture fail under a strong ...
Deciding Eventual Consistency for a Simple Class of Relational Transducer Networks Hasselt University
Networks of relational transducers can serve as a formal model for declarative networking, focusing on distributed database querying applications. In declarative networking, a crucial property is eventual consistency, meaning that the final output does not depend on the message delays and re-orderings caused by the network. Here, we show that eventual consistency is decidable when the transducers satisfy some syntactic restrictions, some of ...

Contrasting geographical distributions as a result of thermal tolerance and long-distance dispersal in two allegedly widespread tropical brown algae Meise Botanic Garden Ghent University
Background: Many tropical marine macroalgae are reported from all three ocean basins, though these very wide distributions may simply be an artifact resulting from inadequate taxonomy that fails to take into account cryptic diversity. Alternatively, pantropical distributions challenge the belief of limited intrinsic dispersal capacity of marine seaweeds and the effectiveness of the north-south oriented continents as dispersal barriers. We aimed ...
Phylogeny and molecular evolution of the green algae Meise Botanic Garden Ghent University
The green lineage (Viridiplantae) comprises the green algae and their descendants the land plants, and is one of the major groups of oxygenic photosynthetic eukaryotes. Current hypotheses posit the early divergence of two discrete clades from an ancestral green flagellate. One clade, the Chlorophyta, comprises the early diverging prasinophytes, which gave rise to the core chlorophytes. The other clade, the Streptophyta, includes the charophyte ...
