A 12-month-old infant presented with cerebral seizures and neurological deficits. MRI scan of the brain and angiography showed massive cerebral venous sinus thrombosis complicated by a dural arteriovenous fistula. Subsequent clotting analysis revealed a protein S deficiency. Screening for inherited coagulation inhibitor deficiency is recommended in children(More)
The detection of structural changes in time series from industrial processes monitoring is of great interest. We investigate the limits and possibilities of two recently developed methods, one for the off-line detection of changed volatilities [Wied et al., 2011] and one for the on-line detection of changes in the course of the time series [Borowski and(More)
To use the manifold possibilities that arc spraying offers to deposit wear resistance layers, the knowledge of the particle formation and their characteristics are necessary. The work is focused on studying the particle trajectories during arc spraying with cored wires. Different cored wires under various spraying parameters are investigated by means of a(More)
A 38-year-old patient showed monocular nonprogressing pigmentary changes for 8 years, with nearly normal blood vessels and scarcely restricted dark-adaptation. ERG and VER were different from those of the other eye. The affected eye had full vision and an annular scotoma corresponding to the pigmentary changes. The other eye was amblyopic due to strabismus.(More)
