p2,-7 The fluid model of electricity is not simply folk-lore. It was proposed independently in 1747 by William Watson in London and Benjamin Franklin in Philadelphia. It had the important consequence of implying the conservation of the total quantity of electricity. Both took advantage of the recent invention of the ‘Leyden jar’ for storing electricity when conducting their experiments. Benjami...

Samuel Johnson was a poet, critic, lexicographer, and the author of the famous Dictionary, which he began in 1747. In 1755, Johnson's Dictionary appeared in two large folio volumes. It represented about 9 years of work and was written almost single handedly. Johnson had only the assistance of a few amanuenses to copy out the quotations he marked. Johnson originally approached Lord Chesterfield ...

In the sequel to [A. Ilchmann and V. Mehrmann, SIAM J. Control Optim., 44 (2005), pp. 1725–1747], we discuss a behavioral approach for linear, time-varying, differential algebraic (descriptor) systems with real analytic coefficients. The analysis is “almost global” in the sense that the analysis is not restricted to an interval I ⊂ R but is allowed for the “time axis” R\T, where T is a discrete...

ISSN 0001-5555 Connective tissue naevi are circumscribed skin lesions characterised by an increase or structural alteration of either collagen or elastin fibres (1). Collagen naevi occur in a patchy form as a feature of tuberous sclerosis, whereas elastin-rich naevi are noted in Buschke-Ollendo...
