    • Compact representation of solution vectors in Kronecker-based Markovian analysis 

      Buchholz, P.; Dayar, Tuğrul; Kriege, J.; Orhan, M. Can (Springer, 2016-08)
      It is well known that the infinitesimal generator underlying a multi-dimensional Markov chain with a relatively large reachable state space can be represented compactly on a computer in the form of a block matrix in which ...
    • Confined linear carbon chains as a route to bulk carbyne 

      Shi, L.; Rohringer, P.; Suenaga, K.; Niimi, Y.; Kotakoski, J.; Meyer, J. C.; Peterlik, H.; Wanko, M.; Cahangirov, S.; Rubio, A.; Lapin, Z. J.; Novotny, L.; Ayala, P.; Pichler, T. (Nature Publishing Group, 2016-04)
      Strong chemical activity and extreme instability in ambient conditions characterize carbyne, an infinite sp1 hybridized carbon chain. As a result, much less has been explored about carbyne as compared to other carbon ...
    • Discovering story chains: a framework based on zigzagged search and news actors 

      Toraman C.; Can, F. (John Wiley and Sons Inc., 2017)
      A story chain is a set of related news articles that reveal how different events are connected. This study presents a framework for discovering story chains, given an input document, in a text collection. The framework has ...
    • Discretization of hyperbolic type Darboux integrable equations preserving integrability 

      Habibullin, I.; Zheltukhina, N.; Sakieva, A. (American Institute of Physics, 2011)
      A method of integrable discretization of the Liouville type nonlinear partial differential equations based on integrals is suggested. New examples of the discrete Liouville type models are presented. © 2011 American Institute ...
    • Highly luminescent CB[7]-based conjugated polyrotaxanes embedded into crystalline matrices 

      Erdem, T.; Idris, M.; Demir, Hilmi Volkan; Tuncel, D. (Wiley-VCH Verlag, 2017)
      π-Conjugated polymers suffer from low quantum yields (QYs) due to chain–chain interactions. Furthermore, their emission in solid films is significantly quenched due to aggregation leading further decrease in QY. These are ...
    • On compact solution vectors in Kronecker-based Markovian analysis 

      Buchholz, P.; Dayar T.; Kriege, J.; Orhan, M. C. (Elsevier, 2017)
      State based analysis of stochastic models for performance and dependability often requires the computation of the stationary distribution of a multidimensional continuous-time Markov chain (CTMC). The infinitesimal generator ...
    • On existence of an x-integral for a semi-discrete chain of hyperbolic type 

      Zheltukhin, K.; Zheltukhina, Natalya (IOP, 2016)
      A class of semi-discrete chains of the form t1x = f (x,t,t1,tx) is considered. For the given chains easily verifiable conditions for existence of x-integral of minimal order 4 are obtained.
    • Thiol passivation of MWIR Type II superlattice photodetectors 

      Salihoğlu, Ömer; Muti, Abdullah; Aydınlı, Atilla (SPIE, 2013)
      Poor passivation on photodetectors can result in catastrophic failure of the device. Abrupt termination of mesa side walls during pixel definition generates dangling bonds that lead to inversion layers and surface traps ...
