On an Extension of a Theorem of Eilenberg and a Characterization of Topological Connectedness

M. Ali Khan, Metin Uyanik

On taking a non-trivial and semi-transitive bi-relation constituted by two (hard and soft) binary relations, we report a (i) p-continuity assumption that guarantees the completenes…

Generating hot carriers in plasmonic nanoparticles: when quantization does and does not matter?

Jacob B Khurgin, Uriel Levy

Plasmon-assisted hot carrier processes in metal nanoparticles can be described either classically or using the full strength of quantum mechanics. We reconfirm that from the practi…

QSO obscuration at high redshift (): Predictions from the BlueTides simulation

Yueying Ni, Tiziana Di Matteo, Roberto Gilli +3

High- AGNs hosted in gas rich galaxies are expected to grow through significantly obscured accretion phases. This may limit or bias their observability. In this work, we use \te…
