A 61-year-old vascular patient presented with headache and subacute blindness in the left eye. Remaining American College of Rheumatology criteria were negative. Sonography of the temporal artery revealed no halo sign, but due to low sensitivity, vasculitis could not be excluded. Transorbital examination revealed hyperechogenic retrobulbar spot sign (figure), which is highly specific for emboli...
ascorbic acid levels were measured and found to be noticeably low (<0.1 mg/dL; normal range, 0.2-0.4 mg/dL), thereby confirming the diagnosis. The patient responded extremely well to oral treatment with vitamin C and nutritional supplements of fruits and vegetables; the skin lesions disappeared within 15 days and his overall health improved noticeably. The peculiar pale orange halo observed on ...
We have performed the largest ever particle simulation of a Milky Way-sized dark matter halo, and present the most comprehensive convergence study for an individual dark matter halo carried out thus far. We have also simulated a sample of 6 ultrahighly resolved Milky-way sized halos, allowing us to estimate the halo-to-halo scatter in substructure statistics. In our largest simulation, we resol...
In this paper we use the “Millennium Simulation” to re-examine the mass assembly history of dark matter halos and the age dependence of halo clustering. We use eight different definitions of halo formation times to characterize the different aspects of the assembly history of a dark matter halo. We find that these formation times have different dependence on halo mass. While some formation time...
Placing a fluid mixture in temperature gradient can cause concentration gradients to build up, phenomenon called the Soret effect. The authors simulate this effect for of monomers and dimers, find contribution from internal degrees freedom dimers. Under some conditions sign is reversed.
