The results of a considerable number of recent prospective studies have demonstrated that greater acute pain severity in herpes zoster patients is associated with a significantly greater risk of developing postherpetic neuralgia (PHN). Only a few studies have examined the relationships between acute pain severity and demographic characteristics and clinical(More)
Classical optical lithography is diffraction limited to writing features of a size l͞2 or greater, where l is the optical wavelength. Using nonclassical photon-number states, entangled N at a time, we show that it is possible to write features of minimum size l͑͞2N͒ in an N-photon absorbing substrate. This result allows one to write a factor of N 2 more(More)
