Although coordination of concurrent objects is a fundamental aspect of object-oriented concurrent programming, there is only little support for its specification and abstraction at the language level. This is a problem because coordination is often buried in the code of the coordinated objects, leading to a lack of abstraction and reuse. Here we present(More)
BACKGROUND The long-term results of total hip arthroplasty performed with cement and use of a bulk autograft for acetabular reconstruction in patients with developmental dysplasia of the hip have varied considerably. We evaluated the results of total hip arthroplasties performed with acetabular bulk autograft to identify the factors that influence the(More)
An important family of existing coordination models and languages is based on the idea of trapping the messages exchanged by the coordinated entities and by the specification of rules governing the coordination. No model, including our CoLaS coordination model, justifies clearly the reason of their coordination rules. Why these rules and not others? Are(More)
Most of the work on coordination technology so far has focused on the development of special coordination languages and environments that provide the basic mechanisms for realizing the coordination layer of an open system. It is clear that the idea of managing separately the coordination aspect from the computation in a language has a lot of advantages in(More)
We present gross and histologic evidence of coinfection in amphibians by fungal-like parasites of the order Dermocystidia (Amphibiocystidium sp.) and the fungus Batrachochytrium dendrobatidis. The condition was observed in frogs Hypsiboas pulchellus (Hylidae) from Uruguay in 2009 to 2012. This report is the first of dermocystids in Neotropical amphibians(More)
