Quasi one-dimensional iron chains are formed in thermally evaporated iron phthalocyanine (FeC32N8H16) thin films on silicon substrates. The chain length is modified by the deposition temperature during growth. Atomic force microscopy images show spherical grains at low deposition temperatures that become highly elongated at high deposition temperatures due to diffusion. The grain distributions ...

Why a Sex Difference in Age-Adjusted Relationship Between Height and Stroke Mortality? To the Editor: We read with interest the study by Hozawa et al,1 who concluded that height is inversely related to stroke mortality and that the relationship is statistically significant among women but not men when adjusted for age. The authors put forward several possible confounding factors including age e...

Glissades are the slow, gliding eye movements often appended to the end of human saccadic eye movements. They have been used as an aid in diagnosing disease states, eg, multiple sclerosis and vascular lesions. Glissades are a consequence of a mismatch between the sizes of the pulse and step components of the pulse-step motoneuronal controller signals. This physiological and simulation study sho...

Letters to the Editor will be published, if suitable, as space permits. They should not exceed 1000 words (typed double-spaced) in length and may be subject to editing or abridgment. Experts 1 consider aortic pulse wave velocity (PWV) as the supreme index of arterial stiffness, mainly because it is an independent predictor of cardiovascular complications. 2 However , the noninvasive assessment ...
