Subtracting Subtractivity

The effect of retraining a damaged connectionist model of single word reading was investigated with the aim of establishing whether plasticity-related changes occurring during the recovery process, have the potential to account for the pattern of dissociations found in brain damaged patients. In particular, we sought to reproduce the strong frequency/consistency interactions found in surface dy...

Adding and Subtracting Eigenspaces

This paper provides two algorithms; one for adding eigenspaces, another for subtracting them, thus allowing for incremental updating and downdating of data models. Importantly, and unlike previous work, we keep an accurate track of the mean of the data, which allows our methods to be used in classification applications. The result of adding eigenspaces, each made from a set of data, is an appro...

Multifaceted Mathematicians

Murderers , Mathematicians ∗

This article outlines the history of our visualization of the interior of the human body. It throws some light on the emotional context and the underlying idea of man. In order of appearance on the historical stage, the leading characters are: painters, murderers (more precisely: executed persons including thieves driven merely by need, women with illegitimate children, etc.), and mathematician...

Subtracting Out Complex Singularities in Numerical Integration

This paper is concerned with the numerical approximation of definite integrals over [—1, 1], in which the function /to be integrated has isolated singularities near [ —1, 1 ]. Complex variable techniques are used to study the effectiveness of the method of subtracting out complex singularities.
