The discrepancy between transit’s large share of local transportation resources and its generally low share of local trips has raised questions about the use of scarce transportation funds for this purpose. We use a regional transport model consistent with utility theory and calibrated for the Washington, D.C., metropolitan area to estimate the travel(More)
We demonstrate experimentally the existence of Josephson junctions having a doubly degenerate ground state with an average Josephson phase ψ=±φ. The value of φ can be chosen by design in the interval 0<φ<π. The junctions used in our experiments are fabricated as 0-π Josephson junctions of moderate normalized length with asymmetric 0 and π regions. We show(More)
Some 4,500 verbal exchanges among residents, and between staff and residents were recorded during structured observations in eight British purpose-built Homes for old people. These interactions were initially categorised as 'supportive/acceptive' or as 'other'. Subsequently, the 'other' data from four of the Homes was further classified as 'instrumental'(More)
