We consider spread-out models of self-avoiding walk, bond percolation, lattice trees and bond lattice animals on Zd , having long finite-range connections, above their upper critical dimensions d = 4 (self-avoiding walk), d = 6 (percolation) and d = 8 (trees and animals). The two-point functions for these models are respectively the generating function for selfavoiding walks from the origin to ...

If black hole formation and evaporation can be described by an S matrix, information would be expected to come out in black hole radiation. An estimate shows that it may come out initially so slowly, or else be so spread out, that it would never show up in an analysis perturbative in MP lanck/M , or in 1/N for two-dimensional dilatonic black holes with a large number N of minimally coupled scal...

Recent evidence that a herpes virus protein lacking a classical secretory signal sequence can spread between cells in culture draws attention to a class of proteins that are transported into and out of cells by unconventional means.

the sharp upper bounds and the sharp lower bounds of the largest eigenvalues $lambda_1$, the least eigenvalue $lambda_n$, the second largest eigenvalue $lambda_2$, the spread and the separator among all firefly graphs on $n$ vertices are determined.
