Physical Review Letters, 2018 A model of cosmological inflation is proposed in which field space is a hyperbolic plane. The inflaton never slow-rolls, and instead orbits the bottom of the potential, buoyed by a centrifugal force. Though initial velocities redshift away during inflation, in negatively curved spaces angular momentum naturally starts exponentially large and remains ...

Movement Disorders in Aicardi–Goutières Syndrome and Response to Immunomodulation
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT This study characterizes movement disorders and treatment responses in seven children with Aicardi–Goutières syndrome (AGS). We retrospectively evaluated motor phenotypes, neuroimaging, and interferon signatures in patients treated with baricitinib or anifrolumab. Spasticity affected all patients, while dystonia was present in 4/7.

Computers & Mathematics with Applications, 1986 AbstractThe use of computer graphics to create repeating patterns of the hyperbolic plane is a recent and natural development in the history of hyperbolic patterns. A program is described which generates such patterns in the Poincaré model of hyperbolic geometry. The program can easily be extended to create patterns with color symmetry.

Platonic Hyperbolic Monopoles [PDF]
Communications in Mathematical Physics, 2014 We construct a number of explicit examples of hyperbolic monopoles, with various charges and often with some platonic symmetry. The fields are obtained from instanton data in four-dimensional Euclidean space that are invariant under a circle action, and in most cases the monopole charge is equal to the instanton charge.

A Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller
International Journal of Adaptive Control and Signal Processing, EarlyView.Block Diagram of the Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller. ABSTRACT This article introduces a discrete‐time robust adaptive one‐sample‐ahead preview super‐twisting sliding mode controller. A stability analysis of the controller by Lyapunov criteria is developed to demonstrate its robustness in handling both ...
