A graph property P is strongly testable if for every fixed > 0 there is a one-sided -tester for P whose query complexity is bounded by a function of . In classifying the strongly testable graph properties, the first author and Shapira showed that any hereditary graph property (such as P the family of perfect graphs) is strongly testable. A property is easily testable if it is strongly testable ...

A profile is “a set of data often in graphic form portraying the significant features of something”. [Web88] Profiles can help us to quickly understand a person or entity better. In the development of computer-based applications, profiles are invaluable. They help us to understand the application – how it works, how well it works, whether it in fact works as we think it does, and whether it is ...

A pomonoid S is a monoid equipped with a partial order that is compatible with the binary operation. In the same way that M -acts over a monoid M correspond to the representation of M by transformations of sets, S-posets correspond to the representation of a pomonoid S by order preserving transformations of posets. Following standard terminology from the theories of R-modules over a unital ring...

John Harris: The only traits it would be morally problematic to induce are those that would be harmful to the individual or to others. It wouldn't be morally problematic if a woman had a boy rather than a girl, or a child with a particular skin or eye colour or high intelligence. No one has a reason to bemoan the birth of such a child. Nor would the child have grounds for complaint. On the othe...

Among the powerful barriers to making progress in patient safety is an attitude of complacency induced by the rarity of serious events and the general human bias toward assuming that things will work as they are supposed to. Although the overall incidence figures for accidental injuries and deaths in healthcare are horrendous—more than 1 million preventable injuries and 44 000–98 000 preventabl...

In two experiments, event-related brain potentials (ERPs) were used to examine the neural correlates of a visual illusion effect in Müller-Lyer illusion tasks (illusion stimuli) and baseline tasks (no-illusion stimuli). The behavioral data showed that the illusion stimuli indeed yielded an illusion effect. Scalp ERP analysis revealed its neurophysiological substrate: the Müller-Lyer illusion ta...
