      Colloquium: The shape of hadrons 

      Alexandrou, Constantia; Papanicolas, Costas N.; Vanderhaeghen, M. (2012)
      This Colloquium addresses the issue of the shape of hadrons and, in particular, that of the proton. The concept of shape in the microcosm is critically examined. Special attention is devoted to properly define the meaning ...

      Electrically tunable spin injector free from the impedance mismatch problem 

      Ando, K.; Takahashi, S.; Ieda, J.; Kurebayashi, H.; Trypiniotis, Theodossis; Barnes, C. H. W.; Maekawa, S.; Saitoh, E. (2011)
      Injection of spin currents into solids is crucial for exploring spin physics and spintronics. There has been significant progress in recent years in spin injection into high-resistivity materials, for example, semiconductors ...

      Evaluating the significance of cognitive and emotional parameters in e-learning adaptive environments 

      Tsianos, Nikos; Germanakos, Panagiotis; Lekkas, Zacharias; Mourlas, Constantinos; Samaras, George S. (2007)
      This paper presents experimental evidence supporting the notion that users' individual information processing characteristics are significant in the context of e-learning environments. In the wider field of Adaptive ...

      A mechanistic approach in defining inelastic rotation capacity of RC columns 

      Megalooikonomou, K. G.; Pantazopoulou, Stavroula J.; Tastani, S. P. (National Technical University of Athens, 2017)
      When a reinforced concrete (RC) column is subjected to lateral sway as a result of earthquake action, the large strain demand in the end sections is supported by development of strains in the anchorage. This causes the ...

      Solid Tumors Are Poroelastic Solids with a Chemo-mechanical Feedback on Growth 

      Ambrosi, D.; Pezzuto, S.; Riccobelli, D.; Stylianopoulos, T.; Ciarletta, P. (2017)
      The experimental evidence that a feedback exists between growth and stress in tumors poses challenging questions. First, the rheological properties (the “constitutive equations”) of aggregates of malignant cells are still ...
