The performance of an ultrasound sphygmomanometer (Arteriosonde 1217) has been compared with that of the London School of Hygiene and Tropical Medicine and Hawksley sphygmomanometers. The Arteriosonde gave closely similar values of systolic blood pressure of the other instruments but diastolic blood pressure lay midway between phase 4 and phase 5 of the Korotkoff sounds. Observers using the Art...

Gori and Hamburger (2006, Perception 35 853-857) devised a new visual illusion of relative motion elicited by the observer's motion. We propose that the systematic error of direction discrimination found by Lorenceau et al (1993, Vision Research 33 1207 - 1217) can explain this illusion. The neural correlate of such a systematic error with respect to the two types of neurons in the primary visu...

Abstract The purpose of this article is to comment on three dance-related passages from the Χρονικὴ διήγησις Byzantine historian Niketas Choniates (1155 ca.–1217). A linguistic analysis will identify both precise classical reminiscences used by author and medieval reality transfigured through his archaizing choices. An introduction summarizes some aspects Constantinopolitan dance in its specifi...

As is well known, it is very difficult to use the Hilger’s integral to consider the existence of periodic solutions of some second order Hamiltonian systems on time scales since it is only concerned with antiderivatives. Therefore, in this paper, we use a new integral on time scales T defined by Rynne (J. Math. Anal. Appl. 328 (2007) 1217–1236), and establish a new existence result for periodic...
