Residual paralysis: a real problem or did we invent a new disease?

Perioperative sleep apnea: a real problem or did we invent a new disease?

Depending on the subpopulation, obstructive sleep apnea (OSA) can affect more than 75% of surgical patients. An increasing body of evidence supports the association between OSA  and perioperative complications, but some data indicate important perioperative outcomes do not differ between patients with and without OSA. In this review we will provide an overview of the pathophysiology of sleep ap...

Anchoring : do we need new solutions to an old problem or do we have old solutions for a new problem ?

We propose a model to represent knowledge in an agent possibly participating to a multi-agent system, such that the anchoring problem can be faced by well known techniques. We discuss how this model could reliably support the instantiation of concepts by aggregating percepts affected by uncertainty, sensed by several sensors, and obtained from different agents.

Did We or Didn't We? Louse Genetic Analysis Says Yes

New gene evolution: little did we know.

Genes are perpetually added to and deleted from genomes during evolution. Thus, it is important to understand how new genes are formed and how they evolve to be critical components of the genetic systems that determine the biological diversity of life. Two decades of effort have shed light on the process of new gene origination and have contributed to an emerging comprehensive picture of how ne...
