Inverse Exit times ∗

Normalized cut is a widely used measure of separation between clusters in a graph. In this paper we provide a novel probabilistic perspective on this measure. We show that for a partition of a graph into two weakly connected sets, V = A B, the multiway normalized cut is approximately MNcut ≈ 1/τA→B + 1/τB→A, where τA→B is the unidirectional characteristic exit time of a random walk from subset ...

Zoology: At Last an Exit for Ctenophores

Ctenophores, one of the most basal branches in the tree of life, have been found to have a through-gut, complete with mouth and anus. Basal animals are surprisingly complex and simplification has been rampant in animal evolution.

Mitochondrial heme: an exit strategy at last.

The transport of heme across membranes is critical for iron absorption, the formation of hemoglobin and other hemoproteins, and iron recycling in macrophages. However, the identity of heme transport proteins has been elusive. In this issue of the JCI, Chiabrando et al. reveal that an isoform of the feline leukemia virus subgroup C receptor (FLVCR1) exports heme from the mitochondria and is crit...

tised and a new system of governance. Of the three key changes advocated in the Kok report, only National Reform Programmes (NRPs) drawn up by the member states made it off the drawing board. The proposals to provide appropriate EU funding to support the Lisbon goals, and “name and shame” poor performing member states were rejected. The driving force of Lisbon 2 is thus national “ownership” of ...

Collision times and exit times from cones: A duality

We consider the first collision time for a set of independent one-dimensional zero-drift Wiener processes. For the 3-process problem, the first collision time corresponds to the first exit time of Brownian motion in a cone in W’, and we can apply the results of Spitzer (1958) and Dante DeBlassie (1987) to obtain its distribution. In the case where the processes have equal infinitesimal variance...
