      Automatic respiratory gating for perfusion quantification of DCEUS 

      Christofides, Damianos; AVERKIOU, MICHALAKIS A.; Leen, Edward (2013)
      A novel automatic respiratory gating (ARG) algorithm for ultrasound is presented. The ARG algorithm was applied on dual contrast imaging (contrast/tissue) loops in order to remove respiratory motion artifacts from dynamic ...

      Evaluation of the Accuracy of Liver Lesion DCEUS Quantification With Respiratory Gating 

      Christofides, Damianos; Leen, Edward; AVERKIOU, MICHALAKIS A. (2016)
      Confidence in the accuracy of dynamic contrast enhanced ultrasound (DCEUS) quantification parameters is imperative for the correct diagnosis of liver lesion perfusion characteristics. An important source of uncertainty in ...

      Kinetic and mechanistic studies of the water-gas shift reaction on Pt/TiO2 catalyst 

      Kalamaras, Christos M.; Panagiotopoulou, P.; Kondarides, D. I.; Efstathiou, Angelos M. (2009)
      A detailed kinetic and mechanistic study of the water-gas shift (WGS) reaction on a 0.5 wt% Pt/TiO2 catalyst has been carried out. The dependence of kinetic reaction rate on the partial pressures of reactants (CO, H2O) and ...

      A new kinetic term in the phenomenology of layered superconductors 

      Theodorakis, Stavros (1993)
      We show that the Lawrence-Doniach free energy for layered superconductors can be derived from an anisotropic Ginzburg-Landau free energy with a spatially dependent coefficient for the quadratic term. Our derivation indicates ...
