... trap states. Furthermore, recombi- nation of electrons from these traps states with holes in the valence band takes *2 ns. Auger recombination has a contribution to the carrier dynamics at the ... Further- more the diameter of the SnO 2 NWs was found to be uniform along their length. The growth of the SnO 2 NWs occurs via the formation of Au nanoparticles (NPs)...

... N candidates in the frame F(t − 1) which yield the N lowest values of the cost function. Then, we continue with the motion estimation for each of the N best candidates found in the frame F (t ... finding their N best matches in the frame F (t − 2). We continue the motion estimation this way until the end of the buffer is reached. This way, by only taking into account...

... [16,20,21] demonstrated the transport of conjugated and unconjugated lipophilic anions by MRP2. The absence of MRP2 from the canalicular membrane of human hepatocytes is the molecular basis of the Dubin–Johnson ... N-terminus of MRP2. The N -terminus of MRP2 is located on the extracellular s ide [16], therefore a cDNA was constructed which led to translation of a...
