      The use of femtosecond laser pulses allows precise and thermal-damage-free removal of material (ablation) with wide-ranging scientific, medical and industrial applications. However, its potential is limited by the low ...
    • Abnormal subcortical activity in congenital mirror movement disorder with RAD51 mutation 

      Demirayak, P.; Onat, O. E.; Gevrekci, A. Ö.; Gülsüner, S.; Uysal, H.; Bilgen, R.; Doerschner, K.; Özçelik, T.; Boyacı, H. (Turkish Society of Radiology, 2018)
      PURPOSE Congenital mirror movement disorder (CMMD) is characterized by unintended, nonsuppressible, homologous mirroring activity contralateral to the movement on the intended side of the body. In healthy controls, unilateral ...
    • About curvature, conformal metrics and warped products 

      Dobarro, F.; Ünal, B. (Institute of Physics Publishing Ltd., 2007)
      We consider the curvature of a family of warped products of two pseduo-Riemannian manifolds (B, gB) and (F, gF) furnished with metrics of the form c2gB ⊕ w2g F and, in particular, of the type w2μgB ⊕ w2gF, where c, w:B → ...
