Foveal threshold elevation and red-green cone pigment regeneration have been studied in the dark after a wide range of bleaches in normal man with a view to probing the limits of the application of the Dowling-Rushton relation: i.e., the direct proportionality between log threshold elevation and fraction of unregenerated pigment. Cone pigment regeneration (and threshold recovery) is much faster...

T here has been a growing awareness of the importance of human resource management (HRM) in tbe global arena and a greater understanding of its international dimensions. This trend is reflected in the "evolution" of texts such as those by Dowling and his colleagues.' However, more "traditional" international HRM (IHRM) texts define the area too narrowly and descriptively, with little backing in...

MICROBIOLOGY Correction for ‘‘Rapid Virulence Annotation (RVA): Identification of virulence factors using a bacterial genome library and multiple invertebrate hosts,’’ by Nicholas R. Waterfield, Maria Sanchez-Contreras, Ioannis Eleftherianos, Andrea Dowling, Paul Wilkinson, Julian Parkhill, Nicholas Thomson, Stuart E. Reynolds, Helge B. Bode, Steven Dorus, and Richard H. ffrench-Constant, which...

Dowling-Degos disease (DDD) is a rare genetic disease of the skin (reticulate pigmented anomaly), clinically characterized by flexural brown pigmented reticulate macules, comedo-like papules on the back, neck and pitted perioral or facial scars. We present the case of a 51 year-old man with macrocomedo-like lesions, pitted scars, cysts, hyperpigmented macules in his back, chest, axillae, neck, ...

This study investigated melody recognition with a modification of the standard-comparison paradigm. Subjects listened to an original melody, were exposed to a silent retention interval, and then were presented with a target and a distractor. There were two types of trials. On target-same trials, listeners heard the target (the original melody) played in the same key exactly as it was previously...

A multiary (polyadic, n-ary) quasigroup is an n-ary operation which is invertible with respect to each of its variables. A biased expansion of a graph is a kind of branched covering graph with additional structure similar to combinatorial homotopy of circles. A biased expansion of a circle with chords encodes a multiary quasigroup, the chords corresponding to factorizations, i.e., associative s...

We present numerical computations that reproduce the time reversal experiments of Draeger, Cassereau and Fink (Draeger et al., 1998), where ultrasound elastic waves are time reversed back to their source with a Time Reversal Mirror (TRM) in a fluid adjacent to the solid. We also show numerically that multipathing caused by random inhomogeneities improves the focusing of the back-propagated elas...
