See-saw nystagmus.
See-saw nystagmus is a rare ocular abnormality, only 15 cases having been recorded to date (Maddox, 1914; Rucker, 1946; Larsen, 1957; Jensen, 1959; Smith and Mark, 1959; Mark, Smith, and Kjellberg, 1960; Lourie, 1963; Schurr, 1963; Kinder and Howard, 1963; Slatt and Nykiel, 1964; and Daroff, 1965). As initially described by Maddox (1914), the eye movements consist of regular reciprocating oscil...
متن کاملSee-saw nystagmus.
See-saw ocular movements are described in two patients, one having obstructive hydrocephalus and the other a thalamic infarct. Electro-oculographic studies demonstrated that the eye movements in patient 1 moved in and out of phase at irregular intervals, in both a horizontal and a vertical direction. The disconjugate eye movements were exaggerated in bright light and less evident during fixatio...
متن کاملA see-saw model of sterile neutrino
If the smallness of the mass of the sterile neutrino is to be explained by seesaw mechanism, the off-diagonal entries of its mass matrix has to be protected by some symmetry near the electroweak scale. We study a gauge model based on SU(2)qL × SU(2) l L × U(1) q Y × U(1) l Y un-unified gauge group which breaks to SU(2)L × U(1)Y at the TeV region and this serves our purpose. The diagonal element...
متن کاملPlaying with a nanoscale see-saw.
My research is on nanooptomechanical systems (NOMS), which are photonic devices designed for studying and controlling light–matter interactions at the nanoscale. I was first introduced to NOMS in the summer of 2010 while searching for an advisor at the University of Minnesota. Holding Bachelor’s and Master’s degrees in Electrical Engineering from Tsinghua University, China, I was hoping to do c...
متن کاملApproximate Flavour Symmetries and See-Saw Mechanism
We study the approximate flavour symmetries imposed on the lepton sector assuming see-saw mechanism as the neutrino mass structure. We apply the symmetry to various neutrino phenomenologies and obtain constraints on neutrino masses and mixings. Typeset using REVTEX [email protected] 1
