Bifurcation Analysis of a Modified Tumorimmune System Interaction Model Involving Time Delay
(EDP Sciences, 2017)We study stability and Hopf bifurcation analysis of a model that refers to the competition between the immune system and an aggressive host such as a tumor. The model which describes this competition is governed by a ... 
Bifurcation Analysis Of A SingleGroup Asset Flow Model
(American Mathematical Society, 2016)We study the stability and Hopf bifurcation analysis of an asset pricing model that is based on the model introduced by Caginalp and Balenovich, under the assumption of a fixed amount of cash and stock in the system. First, ... 
Bifurcation and Stability in a Delayed PredatorPrey Model with Mixed Functional Responses
(World Scientific Publishing Co. Pte Ltd, 201506)The model analyzed in this paper is based on the model set forth by Aziz Alaoui et al. [Aziz Alaoui & Daher Okiye, 2003; Nindjin et al., 2006] with time delay, which describes the competition between the predator and prey. ... 
Bilim, İlahiyat ve Siyasetin Merkezinde Bir Osmanlı Münevveri: Kudüs Patriği Chrysanthos Notaras
(Kebikeç Dergisi İdarehanesi, 2019)The Patriarch of Jerusalem between 1707 and 1730, Chrysanthos Notaras is an extremely important figure both for his activities in the field of science and for Orthodox theology and patriarchal politics. One of the points ... 
Bounds on the expected value of maximum loss of fractional Brownian motion
(Elsevier B.V., 201509)It has been theoretically proven through present study that the expected value of maximum loss of fractional Brownian motion up to fixed time t with Hurst parameter [1/2, 1) is bounded above by tH??/2 and below by tH/2. ... 
Can deception be desirable?
(Sage Publications Ltd, 201703)Critics of deception in research allege harm to society, the discipline of psychology, the researchers and participants. However, neither empirical findings nor a reasonableperson' test seem to support those allegations. ...

Characterisation and enumeration of a class of semibent quadratic Boolean functions
(Inderscience Online, 2015)In this paper, we consider semibentness of quadratic Boolean functions defined for even n and give the characterisation of these functions. Up to our knowledge, semibentness of this class has not been investigated before ... 
Characterization of Absolute and Uniform Continuity
(Hacettepe UniversityHacettepe Üniversitesi, 2020)In the present paper, by considering nonlinear integral operators and using their approximations via regular summability methods, we obtain characterizations for some function spaces including the space of absolutely ... 
A class of nonsymmetric band determinants with the Gaussian qbinomialcoefficients
(Taylor and Francis Ltd., 2017)A class of symmetric band matrices of bandwidth 2r+1 with the binomial coefficients entries was studied earlier. We consider a class of nonsymmetric band matrices with the Gaussian qbinomial coefficients whose upper ... 
Closed Form Evaluation Of Melham's Reciprocal Sums
(Univ Miskolc Inst Math, 2017)Recently Melham [1] gives closed formul ae for certain finite reciprocal sums. In this paper, we present a different approach to compute these sums in closed form. Our approach is straightforward and simple. First we ... 
Closed form evaluation of restricted sums containing squares of Fibonomial coefficients
(Politechnica University of Bucharest, 2016)We give a systematic approach to compute certain sums of squares Fibonomial coefficients with powers of generalized Fibonacci and Lucas numbers as coefficients; the range of the summation is not the natural one but about ... 
Closed form evaluation of sums containing squares of Fibonomial coefficients
(De Gruyter Open Ltd, 201606)We give a systematic approach to compute certain sums of squares of Fibonomial coefficients with finite products of generalized Fibonacci and Lucas numbers as coefficients. The technique is to rewrite everything in terms ... 
Cognitive function in chronic obstructive pulmonary disease: Relationship to global initiative for chronic obstructive lung disease 2011 categories
(WileyBlackwell, 201508)Background and objective: Recently, comorbidities such as impaired cognitive function have been attracting more focus when considering the management of chronic obstructive pulmonary disease (COPD). Here we investigated ... 
Comparison of Nonlocal Operators Utilizing Perturbation Analysis
(Springer Verlag, 2016)We present a comparative study of integral operators used in nonlocal problems. The size of nonlocality is determined by the parameter ?. The authors recently discovered a way to incorporate local boundary conditions into ... 
Complex Dynamics of a DiscreteTime PreyPredator System with Leslie Type: Stability, Bifurcation Analyses and Chaos
(World Scientific, 202008)Dynamic behavior of a discreteTime preypredator system with Leslie type is analyzed. The discrete mathematical model was obtained by applying the forward Euler scheme to its continuousTime counterpart. First, the local ... 
The concept of Hukuhara derivative and Aumann integral for intuitionistic fuzzy number valued functions
(Kyrgyz Turkish Manas UniversityKırgızistan Türkiye Manas Üniversitesi, 2018)In this paper we have rstly dened a metric based on the Hausdor metric in intuitionistic fuzzy environment and studied its properties. Then we have proved that the metric space of intuitionistic fuzzy number valued ... 
Conditioning analysis of nonlocal integral operators in fractional Sobolev spaces
(Society for Industrial and Applied Mathematics Publications, 201403)We study the conditioning of nonlocal integral operators with singular and integrable kernels in fractional Sobolev spaces. These operators are used, for instance, in peridynamics formulation and nonlocal diffusion. In one ...
