Feeding ecology is central to an understanding of the ecology and life-history strategies of species. The abundance and distribution of food can affect a range of life-history traits, including body size, spatial organization or mating system (Partridge & Green, 1985; Vezina, 1985; Gittleman, 1986; Dayan & Simberloff, 1996; Geffen et al., 1996).

We consider a trapped unbalanced Fermi gas at nonzero temperatures where the superfluid Sarma phase is stable. We determine, in particular, the phase boundaries between the superfluid, normal, and phase-separated regions of the trapped unbalanced Fermi mixture. We show that the physics of the Sarma phase is sufficient to understand the recent observations of Zwierlein et al. [Science 311, 492 (...

The concept of quantum monodromy is introduced to give insight into the energy levels of systems with cylindrically symmetrical potential energy barriers. The K structure of bending progressions of bent molecules and the pendular states of dipolar molecules in strong electric ® elds are taken as molecular examples. Results are given for a two-dimensional champagne bottle model, for six computed...

Supervised classification of remotely sensed data using artificial neural networks (ANNs) is largely limited by the number of nodes and architecture of the ANN, given the limited training samples. The best practice is to train a number of networks and choose the one which gives maximum classification accuracy over the data other than the training data set. Recently, consensus schemes using mult...
