Is a Curved Flight Path in SAR Better than a Straight One?
In the plane, we study the transform R f of integrating a unknown function f over circles centered at a given curve . This is a simplified model of SAR, when the radar is not directed but has other applications, like thermoacoustic tomography, for example. We study the problem of recovering the wave front set WF.f /. If the visible singularities of f hit once, we show that WF.f / cannot be reco...

Oncolytic viruses (OVs) preferentially infect and kill cancer cells. Additionally, OV-induced immune responses subvert cancer-associated immunosuppression and promote antitumor immunity. We have recently demonstrated that the complementation of oncolytic virotherapy with gemcitabine accentuates its immunostimulatory effects, hence exerting superior antineoplastic activity.
