iPS-Derived Early Oligodendrocyte Progenitor Cells from SPMS Patients Reveal Deficient In Vitro Cell Migration Stimulation [PDF]

Cells, 2020
The most challenging aspect of secondary progressive multiple sclerosis (SPMS) is the lack of efficient regenerative response for remyelination, which is carried out by the endogenous population of adult oligoprogenitor cells (OPCs) after proper ...

Anti-Hong–Ou–Mandel interference by coherent perfect absorption of entangled photons

New Journal of Physics, 2022
Two-photon interference, known as the Hong–Ou–Mandel effect, has colossal implications for quantum technology. It was observed in 1987 with two photodetectors monitoring outputs of the beamsplitter illuminated by photon pairs: the coincidence rate of the

Infrared dielectric metamaterials from high refractive index chalcogenides

Nature Communications, 2020
High-index dielectric materials are in great demand for nanophotonic applications. Here, the authors show that chalcogenide topological insulators are suitable candidates for dielectric nanophotonics in the infrared spectral range by reporting resonances
