The paper introduces Atlas for Recurrence neighborhood (ARN) Model– a novel topological method for prediction and modeling for a nonlinear time-series that exhibits recurring patterns. According to the model, global manifold of a reconstructed state-space can be approximated by a few overlapping recurrence neighborhoods. The inherent redundancy structure of the delayembedding procedure and the ...

BACKGROUND In this paper we attempt to describe the clinical features, visual outcomes, and surgical results of patients with acute retinal necrosis (ARN) syndrome and elucidate the risk factors for a poor prognosis. We also review the methods of treatment. METHODS This was a retrospective, noncomparative, observational study of patients diagnosed with ARN syndrome. Nine patients (11 eyes) in...

Acute retinal necrosis (ARN) is a clinical syndrome characterized by vitritis, severe occlusive vasculitis which produces a full thickness, necrotizing retinitis. The disease is caused by an acute infection with a member of the herpes virus family,usually VZV or HSV. ARN usually occurs in healthy adults; however immunocompromised patients may also be affected. The prognosis is poor, with signif...

The 2004 grassroots revolution among French researchers, culminating in the estates general held at the end of the year, highlighted the fact that the research structures in France are in dire need of reform (Curr. Biol. 14, R491–R492, R1031). While the spirit of the 2004 revolt has given way to the more quiet, laborious groundwork of structural change, there is still some disagreement over whi...
