OBJECTIVE : The purpose of this consensus conference was to deliberate the evidence regarding whether minimally invasive mitral valve surgery via thoracotomy improves clinical and resource outcomes compared with conventional open mitral valve surgery via median sternotomy in adults who require surgical intervention for mitral valve disease. METHODS : Before the consensus conference, the conse...
This paper updates previous work on the level of consensus in foundational elements of digital evidence examination. Significant consensus is found present only after definitions are made explicit, suggesting that, while there is a scientific agreement around some of the basic notions identified, the use of a common language is lacking.
The evolution of molecular quasispecies on two diierent complex tness landscapes, the Sherrington Kirkpatrick spin glass and the Graph Bipartitioning landscape, is investigated in dependence on replication delity and population size. Three diierent regimes of replication delity are detected. At high copying delity one obtains a population with high mean tness localized around a time independent...
Consensus trees are used in phylogenetics as summaries or representations of sets of source trees. Here we ask ‘How good are consensus trees?’ in the sense of how well do individual consensus trees represent the set of source trees for which they stand? There are many different consensus methods and various contexts in which they may be used (Swofford, 1991; Wilkinson, 1994; Leclerc, 1998). Con...
No consensus regarding optimal treatment or etiology of Preiser disease exists. We described the epidemiology,classification and treatment characteristics of 18 patients with Preiser disease. Patients with changes related to previoustrauma, and without radiographs were excluded. Based on the radiographs at diagnosis, we classified 13 scaphoids asHerbert Lanzetta stage II, four...

Simultaneous tracking and formation control is addressed for a team of autonomous agents that evolve dynamically in a space containing a measurable vector field. Each agent measures the local value of the field along its trajectory and occasionally shares relevant information with other agents, in order to estimate the spatial average obtained from averaging measurements across all agents. Usin...
INTRODUCTION Lesions of the upper digestive tract due to ingestion of caustic agents still represent a major medical and surgical emergency worldwide. The work-up of these patients is poorly defined and no clear therapeutic guidelines are available. PURPOSE OF THE STUDY The aim of this study was to provide an evidence-based international consensus on primary and secondary prevention, diagnosi...
