Connections seem to matter both at the individual level, in terms how well a person, a firm, or a country does, as well as for the aggregate performance of the system. The advantages that accrue from connections suggest that individuals will find it attractive to invest in forming links with others. Individual connections typically have spillovers on other players. These considerations lead us ...

A National Research Council study on connecting quarks with the cosmos has recently posed a number of the more important open questions at the interface between particle physics and cosmology. These questions include the nature of dark matter and dark energy, how the Universe began, modifications to gravity, the effects of neutrinos on the Universe, how cosmic accelerators work, and whether the...

This is an in-progress set of notes describing the often-neglected geometrical, dynamical interpretation of a connection on a manifold. The essential idea is that, while the Levi-Civita connection is associated to the sliding action of parallel transport, it is perhaps more natural to think of a tangent space to a surface being rolled around as we move from point to point. The difference manife...

We describe a secure transformation of stateful connections or parts of them into stateless ones by attaching the state information to the messages. Secret-key cryptography is used for protection of integrity and con dentiality of the state data and the connections. The stateless protocols created in this way are more robust against denial of service resulting from high loads and resource exhau...

Despite the attention attracted by "connectomics", one can lose sight of the very real questions concerning "What are connections?" In the neuroimaging community, "structural" connectivity is ground truth and underlying constraint on "functional" or "effective" connectivity. It is referenced to underlying anatomy; but, as increasingly remarked, there is a large gap between the wealth of human b...

Kenney and Frankland. eLife 2014;3:e05504. DOI: 10.7554/eLife.05504 1 of 3 Autism spectrum disorders—such as Asperger syndrome and childhood autism—have long been known to have a significant genetic component (Ronald and Hoekstra, 2011). However, the biological basis of these disorders has remained largely elusive. Hundreds of genes have been linked to autism spectrum disorders (or ASDs), but m...

" Only connect! That was the whole of her sermon. Only connect the prose and the passion, and both will be exalted, and human love will be seen at its height. Live in fragments no longer. Only connect, and the beast and the monk, robbed of the isolation that is life to either, will die. "

Background. Catheter ablation of accessory atrioventricular (AV) connections using radiofrequency current has been demonstrated to be effective in the majority of patients with the Wolff-Parkinson-White syndrome or paroxysmal supraventricular tachycardia involving a concealed accessory AV connection. However, electrogram criteria have not been established to guide attempts at radiofrequency cat...
