      Addressing the Functional Determinants of FAK during Ciliogenesis in Multiciliated Cells 

      Antoniades, Ioanna; Stylianou, Panayiota; Christodoulou, Neophytos; Skourides, Paris A. (2017)
      We previously identified focal adhesion kinase (FAK) as an important regulator of ciliogenesis in multiciliated cells. FAK and other focal adhesion (FA) proteins associate with the basal bodies and their striated rootlets ...

      The effects of applying cell-suppression and perturbation to aggregated genetic data 

      Antoniades, Athos; Keane, J.; Aristodimou, Aristos; Philipou, Christa; Constantinou, Andreas I.; Georgousopoulos, Christos; Tozzi, Federica; Kyriacou, Kyriacos C.; Hadjisavvas, Andreas; Loizidou, Maria A.; Demetriou, Christiana A.; Pattichis, Constantinos S. (2012)
      The key test for confidence in any association discovered within the medical domain is replication testing. That is, the ability of the association to be detected in independent populations. At the same time, in order to ...

      Enhanced radio resource management algorithms for efficient MBMS service provision in UTRAN 

      Christophorou, C.; Pitsillides, Andreas; Lundborg, T. (2011)
      As currently specified by 3GPP, Multimedia Broadcast Multicast Service (MBMS) bearer services can be provided within a cell either by Point-to-Point (P-t-P) or Point-to-Multipoint (P-t-M) transmission mode, but not both ...

      Enhanced UMTS simulation-based planning in office scenarios 

      Cabral, O.; Velez, F. J.; Hadjipollas, George; Stylianou, Marios; Antoniou, Josephina; Vassiliou, Vasos; Pitsillides, Andreas (Institute of Electrical and Electronics Engineers Inc., 2006)
      Enhanced UMTS traffic characterisation parameters have been addressed for the offices scenario. By using a system level simulator, results concerning QoS measures as packet delay, blocking and handover failure probabilities ...

      Gain Enhancement of Wideband Metamaterial-Loaded Loop Antenna with Tightly Coupled Arc-Shaped Directors 

      Ahdi Rezaeieh, S.; Antoniades, Marcos A.; Abbosh, A. M. (2017)
      A wideband and unidirectional loop antenna with enhanced and stable gain is presented. To reduce the size of the antenna, the loop is loaded with three mu-negative (MNG) metamaterial unit-cells. The proposed unit-cells ...

      Lopsided vortex cells in rotating Bose-Einstein condensates 

      Theodorakis, Stavros (2015)
      The amplitude |Ψ| of the wavefunction of a repulsive Bose-Einstein condensate in a two-dimensional axisymmetric harmonic trap decreases as we go from the center of the condensate towards its edge. Consequently the wavefunction ...

      Mechanical stress regulates tissue oxygenation, cancer cell proliferation and drug delivery during progression of solid tumors 

      Mpekris, F.; Angeli, S.; Pirentis, A. P.; Stylianopoulos, T. (Springer Verlag, 2016)
      Oxygen supply plays a central role in cancer cell proliferation. While vascular density increases at the early stages of carcinogenesis, mechanical solid stresses developed during growth compress tumor blood vessels and, ...
