Abstract: We tracked unlabeled SARS-CoV-2 viruses inside a hollow core optical fiber by elastic light scattering. The simultaneous confinement of particles and light leads to intense scattering, long ...

THz imaging makes it possible to ‘see’ the molecular composition of objects and distinguish between different materials – such as sugar and cocaine, for example. The time-resolved nonlinear ghost ...

It is well known that contextual and multi-scale representations are important for accurate visual recognition. In this paper we present the Inside-Outside Net (ION), an object detector that exploits ...
