Molecular assignment of tissue of origin in cancer of unknown primary may not predict response to therapy or outcome: A systematic literature review
(2009)Background: Gene expression profiling platforms were recently shown to accurately assign cancer of unknown primary (CUP) to a primary tissue of origin, with unknown impact on patient outcome. We examined chemotherapy ...

A new model for selfish routing
(2008)In this work, we introduce and study a new, potentially rich model for selfish routing over non-cooperative networks, as an interesting hybridization of the two prevailing such models, namely the KPmodel [E. Koutsoupias, ...

Photoinduced inverse spin-Hall effect: Conversion of light-polarization information into electric voltage
(2010)The photoinduced inverse spin-Hall effect was observed in a Pt/GaAs hybrid structure. In the GaAs layer, circularly polarized light generates spin-polarized carriers, inducing a pure spin current into the Pt layer through ...
