In visual search experiments we examined whether targets that are distinguished from distracting items solely by a contrary change in color can be sought spatially in parallel. Targets under time-varying illumination pop out if they present a contrary luminance signal; targets under space-varying illumination can be detected in parallel when they are isoluminant. The results suggest that neuron...

A well known challenge faced by any version of metaethical expressivism is to provide an adequate treatment of the so-called Frege-Geach problem. The task is to make sense of logically complex sentences like 'If I insulted the host then I ought to apologize', to do so by making sense of the states of mind such sentences would be used to express, and to preserve the validity of intuitively valid...

Those people who are dangerous often have personality disorders. Should these individuals be dealt with by criminal justice or mental health services? England (note not Scotland) has taken the mental health route with the Dangerous and Severe Personality Disorder Programme. Is this bold move wise or foolish? To answer this question we have both evidence and opinion - neither is conclusive.

We present in this talk different techniques for quickly answer graph problems where some of the nodes may be turn off. Typical graph problems are such as connectivity or distances between pair of nodes but not only. Emergency planing for such problems is achieved by pre-processing the graphs and by virtually preventing all possible subsequent node removals. To obtain efficient data structures,...

We present a dimension analysis of a set of solar type I storms and type IV events with different kind of fine structures, recorded at the Trieste Astronomical Observatory. The signature of such types of solar radio events is highly structured in time. However, periodicities are rather seldom, and linear mode theory can provide only limited interpretation of the data. Therefore, we performed an...
