Recently, it has been suggested that the phenomenology of flat rotation curves observed at large radii in equatorial plane disk galaxies can be explained as a manifestation General Relativity instead effect Dark Matter halos. In this paper, by using well known weak field, low velocity gravitomagnetic formulation GR, expected GR are rigorously obtained for purely baryonic models with realistic d...

We have studied 34 consecutive patients receiving Cotrel- Dubousset instrumentation for a single and flexible thoracic scoliotic curve, evaluating the rib hump deformity from a single CT scan through the apical vertebra of the curve. Using two measures of rotation we found a mean improvement of 25% in the rotation of the vertebra after operation. Any, usually minor, deterioration occurred in th...

We examine the dimension of the invariant measure for some singular circle homeomorphisms for a variety of rotation numbers, through both the thermodynamic formalism and numerical computation. The maps we consider include those induced by the action of the standard map on an invariant curve at the critical parameter value beyond which the curve is destroyed. Our results indicate that the dimens...
