Effects of aberrations on 3D optical topologies

open access: yesCommunications Physics, 2023
Optical knots and links are nontrivial three-dimensional topologies consisting of trajectories of phase or polarisation singularities. They are theoretically predicted and experimentally observed in paraxial and nonparaxial regimes and in random and ...

A random optical parametric oscillator

open access: yesNature Communications, 2023
Synchronously pumped optical parametric oscillators (OPOs) provide ultra-fast light pulses at tuneable wavelengths. Their primary drawback is the need for precise cavity control (temperature and length), with flexibility issues such as fixed repetition ...

The caudate nucleus undergoes dramatic and unique transcriptional changes in human prodromal Huntington’s disease brain

open access: yesBMC Medical Genomics, 2019
Background The mechanisms underlying neurodegeneration in the striatum of Huntingon’s Disease (HD) brain are currently unknown. While the striatum is massively degenerated in symptomatic individuals, which makes cellular characterization difficult, it is
