The concept of golden spectral graphs is introduced and some of their general properties reported. Golden spectral graphs are those having a golden proportion for the spectral ratios defined on the basis of the spectral gap, spectral spread and the difference between the second largest and the smallest eigenvalue of the adjacency matrix. They are good expanders and display excellent synchroniza...

Increasing development across the western United States (USA) elevates concerns about effects on wildlife resources; the golden eagle (Aquila chrysaetos) is of special concern in this regard. Knowledge of golden eagle abundance and distribution across the western USA must be improved to help identify and conserve areas of major importance to the species. We used distance sampling and visual mar...

Fig 2: Reconstructions using different numbers of projections (Np) starting from the beginning of contrast uptake, i.e. projections 1 to 32, projections 1 to 64 etc, for golden angle (top row) and sequential (bottom row) radial data. The plots (right column) show the signal time course from the centre of k-space projections 1 to 201 for golden angle (top) and sequential (bottom) data. Golden An...

Between Ridge Cliff, to the east of Seatown, to Lyme Regis, there are four main cliffed areas, Ridge Cliff, Golden Cap, Cain's Folly and Black Ven, separated by valleys at Seatown, St Gabriel's Water and Charmouth (see Figure 4.1 for general location, and Figure 4.11). There are two pocket-type beaches, the larger between Golden Cap and Lyme Regis, the smaller to the east of Golden Cap at Seato...
