1Dimensional Harnack Estimates
(Amer Inst Mathematical SciencesAims, 2016)Let u be a nonnegative supersolution to a 1dimensional singular parabolic equation of pLaplacian type (1 < p < 2). If u is bounded below on a timesegment {y} x (0, T] by a positive number M, then it has a power like ... 
A Category Approach to Relation Preserving Functions in Rough Set Theory
(Elsevier Science Inc, 2015)The category Rel whose objects are all pairs (U, r), where r is a relation on a universe U, and whose morphisms are relationpreserving mappings is a canonical example in category theory. One of the convenient categories ... 
A Coanalytic Menger Group That Is Not SigmaCompact
(Scientific Technical Research Council TurkeyTubitak, 2018)Under V = L we construct coanalytic topological subgroups of reals, demonstrating that even for definable groups of reals, selection principles may differ. 
A Combined First Principles TDDFT and Experimental Study on the UvVis Spectra Properties of M(PNitrophenyl Azo Resorcinol)(3) Complexes (M: Fe, Cr)
(Scientific Technical Research Council TurkeyTubitak, 2014)UVVis absorption data of pnitrophenyl azo resorcinol (Magneson I) and its 2 Fe(III) and Cr(III) complexes were investigated both experimentally and theoretically. The geometries were optimized at BP86/TZVP level. The ... 
A Comparative Study on Optimization Methods For The Constrained Nonlinear Programming Problems
(Hindawi Publishing Corporation, 2005) 
A Comparison of the Activities of Greek and Turkish Propolis Against Paenibacillus Larvae
(Int Bee Research Assoc, 2014)Propolis has a long history of use in traditional medicine dating back to at least 300 BC, and has been reported to have a broad spectrum of biological activities. Since most studies have to date focused on medical uses ... 
A Generalization of J  Quasipolar Rings
(Univ Miskolc Inst Math, 2017)In this paper we introduce a class of quasipolar rings which is a generalization of Jquasipolar rings. Let R be a ring with identity. An element a is an element of R is called deltaquasipolar if there exists p(2) = p is ... 
A Generalization of Projective Covers
(Academic Press Inc Elsevier Science, 2008)Let M be a left module over a ring R and I an ideal of R. We call (P, f) a projective Icover of M if f is an epimorphism from P to M, P is projective, Ker f subset of I P, and whenever P = Ker f + X, then there exists a ... 
A Generalization Of Rickart Modules
(Belgian Mathematical Soc Triomphe, 2014)Let R be an arbitrary ring with identity and M a right Rmodule with S = End(R) (M). In this paper we introduce piRickart modules as a generalization of Rickart modules. piRickart modules are also a dual notion of dual ... 
A Link Between Cytotoxicity in Cell Culture and Gastrointestinal Side Effects of Oral Anticoagulants: BenchToBedside
(Comenius Univ, 2018)OBJECTIVE: Warfarin and nonvitaminK oral anticoagulants including dabigatran, rivaroxaban, and apixaban are commonly used in the prophylaxis and treatment of systemic embolism and deep vein thrombosis. In this study, we ... 
A MachineLearningDriven Sky Model
(Ieee Computer Soc, 2017) 
A New Class of Unbiased Linear Estimators in Systematic Sampling
(Hacettepe Univ, Fac Sci, 2017)Use of auxiliary variables is very common in estimating various population parameters. In this study, we suggest a class of unbiased linear estimators for estimating the population mean of the study variate y using information ... 
A New Improved Estimator of Population Mean in Partial Additive Randomized Response Models
(Hacettepe Univ, Fac Sci, 2017)In this study, we have developed a new improved estimator for the population mean estimation of the sensitive study variable in Partial Additive Randomized Response Models (RRMs) using two nonsensitive auxiliary variables. ... 
A New Multilayer Feedforward Network Based on Trimmed Mean Neuron Model
(Acad Sciences Czech Republic, Inst Computer Science, 2015)The multilayer perceptron model has been suggested as an alternative to conventional approaches, and can accurately forecast time series. Additionally, several novel artificial neural network models have been proposed as ... 
A New Proposed Model of Restricted Data Envelopment Analysis By Correlation Coefficients
(Elsevier Science Inc, 2013)The concept of efficiency in data envelopment analysis (DEA) is defined as weighted sum of outputs/weighted sum of inputs. In order to calculate the maximum efficiency score, each decision making unit (DMU)'s inputs and ... 
A New Species of Arabis (Brassicaceae) From Inner Anatolia
(Blackwell Publishing Ltd, 2004)A new species of Arabis L., A. erikii Mutlu sp. nov., is described and illustrated. The species is restricted to inner Anatolia, southwest of Sivas. It grows on steppes. Diagnostic morphological characters are given for ... 
A New Species of Viola L. (Violaceae) from South Anatolia
(Academic Press Ltd Elsevier Science Ltd, 2003)A new species of Viola L., Viola yildirimlii M. Ding & Y Bagci sp. nov. from South Anatolia is described and illustrated. It is found on the rocky slopes of Aladag National Park, in the county of Adana, south Turkey, at ...

A Note on Ads* Modules
(Springer Basel Ag, 2012)We study the ADS* modules which are the dualizations of ADS modules studied by Alahmadi et al. ( J Algebra 352: 215222, 2012). Mainly we prove that an amply supplemented module M is ADS* if and only if M1 and M2 are ...
