Extreme multistability in a Josephson-junction-based circuit.

We design and report an electrical circuit using a Josephson junction under periodic forcing that reveals extreme multistability. Its overall state equations surprisingly recall those of a well-known model of Josephson junction initially introduced in our circuit. The final circuit is characterized by the presence of two new and different current sources in parallel with the nonlinear internal current source sin[ϕ(t)] of the Josephson junction single electronic component.

Ophthalmoplegic migraine with persistent dilated pupil.

Ophthalmoplegic migraine is a rare disorder characterized by childhood-onset ophthalmoplegia and migraine headaches. The third cranial nerve is commonly involved, while involvement of the sixth and fourth cranial nerves is uncommon. We present the case study of a 15-year-old female teenager whose condition was diagnosed with ophthalmoplegic migraine when she was 9 years old and since then has experienced multiple and recurrent attacks.
