Reflection of two-dimensional surface polaritons by metallic nano-plates on atomically thin crystals
Published 2023-01-01“…Through our rigorous model, we reveal that, for strongly confined 2DSPs having much larger momentum than free space photons, the interaction results in almost total internal reflection of 2DSPs as the radiative coupling of the 2DSPs to free space is negligible. …”

Chasing the Beginning of Reionization in the JWST Era
Published 2025-01-01“…Recent JWST observations at z > 6 may imply galactic ionizing photon production above prior expectations. Under observationally motivated assumptions about escape fractions, these suggest a z ~ 8–9 end to reionization, in tension with the z < 6 end required by the Ly α forest. …”

ET-1 Plasma Levels, Aqueous Flare, and Choroidal Thickness in Patients with Retinitis Pigmentosa
Published 2015-01-01“…Higher aqueous flare values were also demonstrated in RP compared to controls: in detail, 10.51±3.97 versus 5.66±1.29 photon counts/ms, P<0.0001. Spearman’s correlation test highlighted that the increase of ET-1 plasma levels was related with the decrease of choroidal thickness (r=-0.702; P<0.023) and the increase of aqueous flare (r=0.580; P<0.007). …”
