      N and N to Δ transition form factors from lattice QCD 

      Alexandrou, Constantia (2007)
      We present recent lattice QCD results on nucleon form factors and N to Δ transition form factors. We predict the parity violating asymmetry in N to Δ and check the off-diagonal Goldberger-Treiman relation.

      N to Δ electromagnetic and axial form factors in full qcd 

      Alexandrou, Constantia (2008)
      Lattice results on the N to Δ electromagnetic, axial-vector and pseudoscalar form factors are evaluated using dynamical staggered sea quarks and domain wall valence quarks for pion masses in the range of 580-350 MeV, as ...

      N-ality and topology at finite temperature 

      Del Debbio, I.; Panagopoulos, Haralambos G.; Vicari, E. (2005)
      We study [JHEP 0309 (2003) 034] the spectrum of confining strings in SU(3) pure gauge theory, in different representations of the gauge group. Our results provide direct evidence that the string spectrum agrees with ...

      N-alpha-terminal Acetylation of Histone H4 Regulates Arginine Methylation and Ribosomal DNA Silencing 

      Schiza, V.; Molina-Serrano, D.; Kyriakou, DImitris; Hadjiantoniou, A.; Kirmizis, Antonis (2013)
      Post-translational modifications of histones play a key role in DNA-based processes, like transcription, by modulating chromatin structure. N-terminal acetylation is unique among the numerous histone modifications because ...

      N-to-p transition on K2Bi8-xSbxSe 13 series 

      Kyratsi, Theodora; Hatzikraniotis, E.; Tsiappos, A.; Paraskevopoulos, K. M.; Kanatzidis, M. G. (Affiliation: Department of Mechanical and Manufacturing Engineering, University of Cyprus, 1678 Nicosia, CyprusAffiliation: Department of Chemistry, Michigan State University, East Lansing, MI 48824, United StatesAffiliation: Department of Physics, Aristotle University of Thessaloniki, 54124 Thessaloniki, GreeceCorrespondence Address: Kyratsi, Th.Department of Mechanical and Manufacturing Engineering, University of Cyprus, 1678 Nicosia, Cyprus, 2006)
      β-K2Bi8Se13 and its solid solutions have been found to be interesting for thermoelectric investigations mainly due to their low thermal conductivity and highly anisotropic electrical properties. Solid solution series of ...

      N-to-Δ axial transition form factors from lattice QCD 

      Alexandrou, Constantia; Leontiou, Theodoros; Negele, J. W.; Tsapalis, Antonios (2007)
      We evaluate the N to Δ axial transition form factors in lattice QCD with no dynamical sea quarks, with two degenerate flavors of dynamical Wilson quarks, and using domain wall valence fermions with three flavors of staggered ...

      N-to-Δ electromagnetic-transition form factors from lattice QCD 

      Alexandrou, Constantia; De Forcrand, P.; Neff, H.; Negele, J. W.; Schroers, W.; Tsapalis, Antonios (2005)
      The magnetic dipole (M1), the electric quadrupole (E2), and the Coulomb quadrupole (C2) amplitudes for γN → Δ are calculated in quenched lattice QCD. Using a new method, which combines an optimal choice of interpolating ...

      N2O decomposition over ceria-promoted Ir/Al2O3 catalysts: The role of ceria 

      Pachatouridou, E.; Papista, E.; Delimitis, Andréas; Vasiliades, Michalis A.; Efstathiou, Angelos M.; Amiridis, Michael D.; Alexeev, O. S.; Bloom, D.; Marnellos, G. E.; Konsolakis, M.; Iliopoulou, E. (2016)
      The impact of CeO2 in the Al2O3-20wt% CeO2 support prepared by the co-precipitation method on the Ir particle size, morphology and oxidation state, and in turn on the deN2O catalytic activity (1000ppmN2O) of supported Ir ...
