Plant Signaling: Notes from the Underground

New studies combining genetic and grafting approaches in Arabidopsis provide evidence that a carotenoid derivative is a novel plant signaling molecule through which roots can influence shoot branching and leaf development.

250th Anniversary of the 1755 Lisbon Earthquake

A probabilistic method that takes account of the ordinal character of the MSK Scale has been adapted to generate a 1755 seismic intensity map for the Iberian Peninsula. Statistical models are employed to estimate isoseismals and to compute standard error uncertainties. The output includes intensity maps, estimates of the effects associated with each intensity level, and estimates of the distrib...

The cost of global replacement of aging underground facilities is prohibitive. Consequently, utilities require an enterprise approach to managing underground power ca...

Notes from the Underground: À Propos of Givental’s Conjecture

These brief notes record our puzzles and findings surrounding Givental’s recent conjecture which expresses higher genus Gromov-Witten invariants in terms of the genus-0 data. We limit our considerations to the case of a projective line, whose GromovWitten invariants are well-known and easy to compute. We make some simple checks supporting his conjecture.
