We consider plane waves propagating in quadratic nonlinear slab waveguides with nonlinear quasi-phase-matching gratings. We predict analytically and verify numerically the complete gain spectrum for transverse modulational instability, including hitherto undescribed higher-order gain bands.

The Cotard syndrome is characterized by the delusion where an individual insists that he has died or part of his body has decayed. Although described classically in schizophrenia and bipolar disorder, physical disorders including migraine, tumour and trauma have also been associated with the syndrome. Two new cases are described here, the one associated with arteriovenous malformations and the other with probable multiple sclerosis. The delusion has been embarrassing to each patient. Study of such cases may have wider implications for the understanding of the psychotic interpretation of body image, for example that occurring in anorexia nervosa.

In 1969, Denniston gave a construction of maximal arcs of degree n in Desarguesian projective planes of even order q, for all n dividing q. Recently, Mathon gave a construction method that generalized that of Denniston. In this paper we use that method to give maximal arcs that are not of Dermiston type for all n dividing q, 4 < n < q/2, q even. It is then shown that there are a large number of isomorphism classes of such maximal arcs when n is approximately rootq. (C) 2003 Elsevier Ltd. All rights reserved.
