Dendrimers are the unique chemical trees with maximum spectral radius
(Univ Kragujevac, 2012)It is shown that dendrimers have maximum spectral radius and maximum CollatzSinogowitz index among all chemical trees of given size. The result is also generalized for the class of chemical trees with prescribed number ... 
Discovering cisregulatory modules by optimizing barbecues
(Elsevier Science Bv, 20090528)Gene expression in eukaryotic cells is regulated by a complex network of interactions, in which transcription factors and their binding sites on the genomic DNA play a determining role. As transcription factors rarely, if ... 
Discrete dynamical systems over double crossproduct Lie groupoids
(World Scientific, 202103)Discrete EulerLagrange equations are studied over double cross product Lie groupoids. As such, a geometric framework for the local analysis of a discrete dynamical system is established. The arguments are elucidated on ... 
Dynamic extension of a compressible nonlinearly elastic membrane tube
(Oxford Univ Press, 200502)The dynamic response of an isotropic compressible hyperelastic membrane tube is considered when one end is fixed and the other is subjected to a suddenly applied dynamic extension. The equations governing dynamic axially ... 
The dynamic response of an incompressible nonlinearly elastic membrane tube subjected to a dynamic extension
(PergamonElsevier Science Ltd, 200406)The dynamic response of an isotropic hyperelastic membrane tube, subjected to a dynamic extension at its one end, is studied. In the first part of the paper, an asymptotic expansion technique is used to derive a nonlinear ... 
The effect of a bump on wave propagation in a fluidfilled elastic tube
(PergamonElsevier Science Ltd., 200401)In the present work, treating the arteries as a thin walled prestressed elastic tube with variable crosssection, and using the longwave approximation, we have studied the propagation of weakly nonlinear waves in such a ...

Eshelby tensors for a spherical inclusion in microstretch elastic fields
(Elsevier Ltd, 200608)In the present work, microelastic and macroelastic fields are presented for the case of spherical inclusions embedded in an infinite microstretch material using the concept of Green's functions. The Eshelby tensors are ... 
Eşlenmiş Lie grupları üzerindeki Lagrange fark denklemleri
(Marmara Üniversitesi Fen Bilimleri Enstitüsü, 20210309)Bu makalede, kesikli (discrete) dinamiğin Lagrange formülasyonu eşlenmiş (matched pair) Lie grupları üzerinde çalışılmıştır. Sonuç olarak, karşılıklı etkileşim altındaki iki sistemin kolektif davranışını belirleyen eşlenmiş ... 
Exact solution of perturbed Kdv equation with variable dissipation coefficient
(Ministry Communicatios & High Technologies Republic Azerbaijan, 2017)In the present work we study the integrability condition for a variable coefficient KortewegdeVries(KdV) equation. For that purpose, we first introduce some proper transformations for dependent and independent variables ... 
Extended reductive perturbation method and its relation to the renormalization method
(Walter De Gruyter GMBH, 20131025)In this work, by utilizing the extended reductive perturbation method, we studied the propagation of weakly nonlinear waves in a collisionless cold plasma and formally obtained the governing evolution equations of various ... 
An extension of a boundedness result for singular integral operators
(Polska Akademia Nauk, 20160330)We study some operators originating from classical Littlewood–Paley the ory. We consider their modification with respect to our discontinuous setup, where the un derlying process is the product of a onedimensional ... 
Extension of mikhlin multiplier theorem to fractional derivatives and stable processes
(Walter De Gruyter GMBH, 20180425)In this paper, we prove a new generalized Mikhlin multiplier theorem whose conditions are given with respect to fractional derivatives in integral forms with two different integration intervals. We also discuss the connection ... 
Facility placement with subaisle design in an existing layout
(Elsevier Science BV, 20090816)In this paper, we consider the integration of facility placement in an existing layout and the configuration of one or two connecting subaisles. This is relevant, for example, when placing a new machine/department on a ... 
Forced KdV equation in a fluidfilled elastic tube with variable initial stretches
(PergamonElsevier Science Ltd, 200911)In this work, by utilizing the nonlinear equations of motion of an incompressible, isotropic thin elastic tube subjected to a variable initial stretches both in the axial and the radial directions and the approximate ...

Fourcycled graphs with topological applications
(Birkhauser Verlag AG, 201203)We call a simple graph G a 4cycled graph if either it has no edges or every edge of it is contained in an induced 4cycle of G. Our interest on 4cycled graphs is motivated by the fact that their clique complexes play an ... 
Fractional Hankel and Bessel wavelet transforms of almost periodic signals
