Algebra with Indefinite Involution and Its Representation in Krein Space
It is often inevitable to introduce an indefinite-metric space in quantum field theory, for example, which is explained for the sake of the manifestly covariant quantization of the electromagnetic field.

This research is part of the Scottish Government’s GreenHealth project. It asks if there is a link between green space and stress in deprived urban communities. Overall, it finds evidence that more urban green space is favourably associated with lower levels of selfreported stress and reduced physiological stress, as indicated by diurnal salivary cortisol patterns in a sample of middle-aged men...
