Of Synuclein and Other Demons

Of the Hennessy-Milner Property and other Demons

We relate three different, but equivalent, ways to characterise behavioural equivalence for set coalgebras. These are: using final coalgebras, using coalgebraic languages that have the HennessyMilner property and using coalgebraic languages that have “logical congruences”. On the technical side the main result of our paper is a straightforward construction of the final T -coalgebra of a set fun...

On Demons and Oracles

Implementing Demons and Ratchets

Experimental results show that ratchets may be implemented in semiconductor and chemical systems, bypassing the second law and opening up huge gains in energy production. This paper summarizes or describes experiments and results on systems that effect demons and ratchets operating in chemical or electrical domains. One creates temperature differences that can be harvested by a heat engine. A s...

Interaction between α-Synuclein and Other Proteins in Neurodegenerative Disorders

Protein aggregation is a common characteristic of many neurodegenerative disorders, and the interaction between pathological/toxic proteins to cause neurodegeneration is a hot topic of current neuroscience research. Despite clinical, genetic, and experimental differences, evidence increasingly indicates considerable overlap between synucleinopathies and tauopathies or other protein-misfolding d...

Fabulous beasts and demons

Mythical beasts and fabulous animals have always proved to be a popular theme and many books describing them have already appeared. This one, however, is probably the largest, and certainly the most sumptuously illustrated. It also deals more adequately with the rich oriental aspects of the theme than most of its predecessors. Written by a professor of oriental archaeology in the University of ...
