KLP Not Always Efficient

The size of the nondominated set of a vector set is greatly dependent on the size of the original vector set N and the dimension of the vector M . Theoretical analysis shows that when M = O(log N) the original set has big nondominated set which may be the original set itself, and in the case M = O(log N), a classical algorithm (KLP) for finding nondominated set has complexity of KLP higher than...

Small is not always beautiful

Peer-to-peer content distribution systems have been enjoying great popularity, and are now gaining momentum as a means of disseminating video streams over the Internet. In many of these protocols, including the popular BitTorrent, content is split into mostly fixed-size pieces, allowing a client to download data from many peers simultaneously. This makes piece size potentially critical for perf...

Eisenmenger syndrome: not always inoperable.

Recently, advanced therapies for pulmonary arterial hypertension have become available, and have been effective in reducing pulmonary vascular resistance and symptoms in patients with Eisenmenger syndrome, previously thought to be inoperable. This review summarizes the current knowledge on the pathophysiology and treatment of Eisenmenger syndrome. The recent introduction of targeted therapies ...

Strength in numbers? Not always!

We propose a simple model to compute the probability of success under a quorum sensing strategy. We show that a quorum sensing strategy has a higher probability of success than an individualistic strategy when, for instance, the probability of success for a single individual is low and the cost of building a quorum is not too high. On the other hand if the cost of building a quorum is too high ...
