    • Paracompactness And Full Normality In Ditopological Texture Spaces 

      Brown, LM; Diker, M (Academic Press Inc, 1998)
      In this paper the authors lay the foundation for a theory of dicovers of ditopological texture spaces and use this to define notions of paracompactness and full normality. Some applications to fuzzy topology are also ...

    • Plain Ditopological Texture Spaces 

      Tiryaki, Ismail U.; Brown, Lawrence M. (Elsevier Science Bv, 2011)
      Using the characterization of plain textures in terms of posets given by Mustafa Demirci (M. Demirci, Textures and C-spaces, Fuzzy Sets and Systems 158 (11) (2007) 1237-1245), the authors consider the important class of ...

    • Polygon Morphing and Its Application in Orebody Modeling 

      Ilhan, Hacer; Gurcay, Hasmet (Hindawi Publishing Corporation, 2012)
      Three different polygon morphing methods are examined. The first one is based on the utilization of the trimmed skeleton of the symmetric difference of the source and target polygons as an intermediate polygon. The second ...

    • Qualitative Results on the Dynamics of A Berger Plate with Nonlinear Boundary Damping 

      Geredeli, Pelin G.; Webster, Justin T. (Pergamon-Elsevier Science Ltd, 2016)
      The dynamics of a (nonlinear) Berger plate in the absence of rotational inertia are considered with inhomogeneous boundary conditions. In our analysis, we consider boundary damping in two scenarios: (i) free plate boundary ...

    • Quantitative Homogenization of Attractors of Non-Newtonian Filtration Equations

      For a rapidly spatially oscillating nonlinearity g we compare solutions u(is an element of) of non-Newtonian filtration equation partial derivative(t)beta(u(is an element of)) - D(vertical bar Du(is an element of)vertical ...

    • Quasipolar Subrings of 3 X 3 Matrix Rings 

      Gurgun, Orhan; Halicioglu, Sait; Harmanci, Abdullah (Sciendo, 2013)
      An element a of a ring R is called quasipolar provided that there exists an idempotent p is an element of R such that p is an element of comm(2)(a), a + p is an element of U(R) and ap is an element of R-qnil. A ring R is ...

    • Quasipolarity of Special Morita Context Rings 

      Gurgun, O.; Halicioglu, S.; Harmanci, A. (Univ Miskolc Inst Math, 2018)
      In this paper, we introduce a new concept of Morita context rings which we call special Morita context rings. We determine the conditions under which this kind of rings are quasipolar. We use special Morita context rings ...

    • Rational Drug Redesign to Overcome Drug Resistance in Cancer Therapy: Imatinib Moving Target 

      Fernandez, Ariel; Sanguino, Angela; Peng, Zhenghong; Crespo, Alejandro; Ozturk, Eylem; Zhang, Xi; Wang, Shimei; Bornmann, William; Lopez-Berestein, Gabriel (Amer Assoc Cancer Research, 2007)
      Protein kinases are central targets for drug-based cancer treatment. To avoid functional impairment, the cell develops mechanisms of drug resistance, primarily based on adaptive mutations. Redesigning a drug to target a ...

    • Real Dicompact Textures 

      Yildiz, Filiz; Brown, Lawrence M. (Elsevier Science Bv, 2009)
      A notion of real compactness for completely biregular bi-T-2 ditopological texture spaces is defined and studied under the name real dicompactness. In particular it is shown that real dicompact spaces are nearly plain ...

      Yildiz, Filiz; Brown, Lawrence M. (Elsevier Science Bv, 2009)
      Real dicompactifications and dicompactifications of a ditopological texture space are defined and studied. Section 2 considers nearly plain extensions of a ditopological texture space (S, S, iota, kappa). Spaces that possess ...

    • Reduced and P.Q.-Baer Modules 

      Baer, Muhittin; Harmanci, Abdullah (Mathematical Soc Rep China, 2007)
      In this paper, we study p.q.-Baer modules and some polynomial extensions of p.q.-Baer modules. In particular, we show: (1) For a reduced module M-R,M-R is ap.p.-moduleiff M-R is a p.q.-Baer module. (2) If M-R is an ...

    • Rings Close to Semiregular 

      Aydoğdu, Pınar; Lee, Yang; Ozcan, A. Cigdem (Korean Mathematical Soc, 2012)
      A ring R is called semiregular if R/J is regular and idempotents lift modulo J, where J denotes the Jacobson radical of R. We give some characterizations of rings R such that idempotents lift modulo J, and R/J satisfies ...
