Any linear code with a nontrivial automorphism has the structure of a module over a polynomial ring. The theory of Griihner bases for modules gives a compact description and implementation of a systematic encoder. We present examples of algebraic-geometric Goppa codes that can be encoded by these methods, including the one-point Hermitian codes. L ET X be a… (More)
Comments on the article by Miller and Campbell (see record 2010-17135-004). The expression of narcissism spans the continuum from normal to pathological and has meaningful correlates in clinical and nonclinical populations. There is growing speculation that narcissism also contributes to major societal concerns (e.g., terrorism and corporate malfeasance).… (More)
The present study is the first independent investigation of the Comprehensive Trail Making Test (CTMT; Reynolds, 2002) with both clinical and non-clinical samples. We examined convergent and divergent validity by exploring relationships between the CTMT and other measures. Discriminant validity was examined by comparing CTMT scores of non-clinical and… (More)
We describe dynamical properties of a map F defined on the space of rational functions. The fixed points of F are classified and the long time behavior of a subclass is described in terms of Eulerian polynomials.
UNLABELLED BACKGROUND The clinical global impression of severity (CGI-S) scale is a frequently used rating instrument for the assessment of global severity of illness in Central Nervous System (CNS) trials. Although scoring guidelines have been proposed to anchor these scores, the collection of sufficient documentation to support the derived score is not… (More)
In this paper we propose a new technique for modeling three-dimensional rigid objects by encoding the fluctuation of the surface and the variation of its normal around an oriented surface point, as the surface expands. The surface of the object is encoded into three vectors as the surface signature on each point, and then the collection of signatures is… (More)
