Differentially Regulated Adamts1, 8, And 18 In Gastric Adenocarcinoma
(Comenius Univ, 2017)OBJECTIVE: The aim is to investigate the expression status of ADAMTS1,8, and 18 proteases in gastric cancer (GC) and lymphatic metastasis. BACKGROUND: A disintegrin and metalloprotease with thrombospondin motifs (ADAMTS) ... -
Vascular Endothelial Growth Factor (Vegf)-C, Vegf-D, Vegfr-3 And D2-40 Expressions In Primary Breast Cancer: Association With Lymph Node Metastasis
(Wroclaw Medical Univ, 2017)Background. Two members of the vascular endothelial growth factor (VEGF) family, VEGF-C and -D, are known as lymphangiogenic growth factors and play an important role in tumor lymphangiogenesis via activation of the VEGF ... -
Efficiency Of State Universities In Turkey During The 2014-2015 Academic Year And Determination Of Factors Affecting Efficiency
(Turkish Education Assoc, 2017)The concepts of efficiency and productivity are of vital importance in a world of limited resources. In this study, the productivity of state universities in Turkey is determined through data envelopment analysis, and the ... -
Odd Burr Lindley Distribution With Properties And Applications
(Hacettepe Univ, Fac Sci, 2017)In this study, we introduce a new model called the Odd Burr Lindley distribution which extends the Lindley distribution and has increasing, bathtub and upside down shapes for the hazard rate function. It includes the odd ... -
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 non-sensitive auxiliary variables. ... -
Autocorrelation Corrected Standard Error For Two Sample T-Test Under Serial Dependence
(Hacettepe Univ, Fac Sci, 2017)The classical two-sample t-test assumes that observations are independent. A violation of this assumption could lead to inaccurate results and incorrectly analyzing data leads to erroneous statistical inferences. However, ... -
Hybrid Non-Dominated Sorting Genetic Algorithm With Adaptive Operators Selection
(Elsevier Science Bv, 2017)Multiobjective optimization entails minimizing or maximizing multiple objective functions subject to a set of constraints. Many real world applications can be formulated as multi-objective optimization problems (MOPs), ... -
Hybrid Adaptive Evolutionary Algorithm Based On Decomposition
(Elsevier Science Bv, 2017)The performance of search operators varies across the different stages of the search/optimization process of evolutionary algorithms (EAs). In general, a single search operator may not do well in all these stages when ... -
Hartley-Ross Type Unbiased Estimators Using The Stratified Random Sampling
(Hacettepe Univ, Fac Sci, 2017)This study mentions Hartley-Ross type unbiased ratio estimators of the finite population mean in the stratified random sampling using the auxiliary variable. We propose the unbiased estimators using the estimators in Kadilar ... -
The Exponentiated Kumaraswamy-Power Function Distribution
(Hacettepe Univ, Fac Sci, 2017)In this paper, the exponentiated Kumaraswamy-power function distribution is introduced. Some structural properties of the proposed distribution including the shapes of the density, hazard and quantile functions are explored. ... -
The Lindley Family Of Distributions: Properties And Applications
(Hacettepe Univ, Fac Sci, 2017)In this paper, we propose a new class of distributions called the Lindley generator with one extra parameter to generate many continuous distributions. The new distribution contains several distributions as sub-models, ... -
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 ... -
The Lindley Weibull Distribution: Properties And Applications
(Acad Brasileira De Ciencias, 2018)We introduce a new three-parameter lifetime model called the Lindley Weibull distribution, which accommodates unimodal and bathtub, and a broad variety of monotone failure rates. We provide a comprehensive account of some ...
