C OMROE, Nisell and Nims (I) have suggested that measurements upon purely passive expiration curves may be used as a rapid method for demonstrating changes in the mechanical properties of the lungs and thorax of animals and man. Essentially, their technique consists of inflating the lungs of animals or man (made apneic by deep anesthesia, curarization, or hyperventilation) to a known alveolar p...

In this paper, we propose a new family of communication architectures, called “biswapped networks” (BSNs). Each BSN is built of 2n copies of some n-node basis network using a simple rule for connectivity that ensures its regularity, modularity, fault tolerance, and algorithmic efficiency. In particular, if the basis network is a Cayley digraph then so is the resulting BSN. Our biswapped connect...

We examined the seasonal movements of wing-tagged and radio-marked adult female Great Bustards Otis tarda in a population in northwestern Spain. Four different movement patterns were found: females that migrated between breeding and wintering areas (20%) females that only left their year-round home range area to mate (32%), females that migrated from a wintering-mating area to a nesting-summeri...

Researchers and practitioners alike often need to understand and characterize how water and solutes move through a stream in terms of the relative importance of in-stream and near-stream storage and transport processes. In-channel and subsurface storage processes are highly variable in space and time and difficult to measure. Storage estimates are commonly obtained using transient-storage model...
