Correlation of upper airway radiographic measurements with risk status for obstructive sleep apnea syndrome in young dental patients
(Elsevier Science Inc, 2017)Objective. The aim of the present study is to compare radiographic measurements of the upper airway (UA) in young adult patients with different levels of risk status for obstructive sleep apnea syndrome. Study Design. The ... -
The Statistical Analysis of the Earthquake Hazard for Turkey by Generalized Linear Models
(Gazi Univ, 2017)In this paper, 4863 earthquake data of magnitude 4.0 and greater from 1900 to 2014 are statistically analyzed for the earthquake hazard in Turkey. The magnitude-frequency relationship in earthquake risk analysis is often ... -
Does the sex of one's co-twin affect height and BMI in adulthood? A study of dizygotic adult twins from 31 cohorts
(Bmc, 2017)Background: The comparison of traits in twins from opposite-sex (OS) and same-sex (SS) dizygotic twin pairs is considered a proxy measure of prenatal hormone exposure. To examine possible prenatal hormonal influences on ... -
Parameter estimation of some Kumaraswamy-G type distributions
(Springer Heidelberg, 2017)Since Kum-G distributions have additional two parameters, the estimation of parameters becomes an interesting problem by itself. In this study, we consider parameter estimation of Kum-Weibull, Kum-Pareto and Kum-Power ... -
Differences in genetic and environmental variation in adult BMI by sex, age, time period, and region: an individual-based pooled analysis of 40 twin cohorts
(Oxford Univ Press, 2017)Background: Genes and the environment contribute to variation in adult body mass index [BMI (in kg/m(2))], but factors modifying these variance components are poorly understood. Objective: We analyzed genetic and environmental ... -
Education in Twins and Their Parents Across Birth Cohorts Over 100 years: An Individual-Level Pooled Analysis of 42-Twin Cohorts
(Cambridge Univ Press, 2017)Whether monozygotic (MZ) and dizygotic (DZ) twins differ from each other in a variety of phenotypes is important for genetic twin modeling and for inferences made from twin studies in general. We analyzed whether there ... -
Assessment of Third Molar Impaction Pattern and Associated Clinical Symptoms in a Central Anatolian Turkish Population
(Karger, 2016)Objectives: The purpose of this study was to assess the pattern of third molar impaction and associated symptoms in a Central Anatolian Turkish population. Material and Methods: A total of 2,133 impacted third molar teeth ... -
Statistical Analysis For Determining The Range Performance Of 155 Mm Heer/Bb Artillery Ammunition
(Destech Publications, Inc, 2016)155 mm MKE MOD274 HEER/Base Bleed ammunition having 39 km range at sea level can be used with NATO 52 caliber Weapon Systems. During the preparation of firing control input / tabular firing table of the projectile for T-155 ... -
Restricted Estimator in Two Seemingly Unrelated Regression Model
(Univ Punjab, 2016)This article is concerned with the estimation problem of multicollinearity in two seemingly unrelated regression (SUR) equations with linear restrictions. We propose a restricted feasible SUR estimates of the regression ... -
Bacterial adhesion to braided surgical sutures: an in vitro study
(Springer, 2016)Background Surgical suture materials are accepted to be associated with a substantial proportion of surgical site infections. These infections are related with biofilm formation similar to that of other synthetic and ... -
Genetic and environmental influences on height from infancy to early adulthood: An individual-based pooled analysis of 45 twin cohorts
(Nature Publishing Group, 2016)Height variation is known to be determined by both genetic and environmental factors, but a systematic description of how their influences differ by sex, age and global regions is lacking. We conducted an individual-based ... -
Genetic and environmental effects on body mass index from infancy to the onset of adulthood: an individual-based pooled analysis of 45 twin cohorts participating in the COllaborative project of Development of Anthropometrical measures in Twins (CODATwins) study
(Oxford Univ Press, 2016)Background: Both genetic and environmental factors are known to affect body mass index (BMI), but detailed understanding of how their effects differ during childhood and adolescence is lacking. Objectives: We analyzed the ... -
A Pseudo-Pareto Distribution and Concomitants of Its Order Statistics
(Springer, 2016)Pareto distributions are very flexible probability models with various forms and kinds. In this paper, a new bivariate Pseudo-Pareto distribution and its properties are presented and discussed. Main variables, order ... -
Performance and stochastic stability of the adaptive fading extended Kalman filter with the matrix forgetting factor
(Sciendo, 2016)In this paper, the stability of the adaptive fading extended Kalman filter with the matrix forgetting factor when applied to the state estimation problem with noise terms in the non-linear discrete-time stochastic systems ... -
Generalized pseudo null Bertrand curves in semi-Euclidean 4-space with index 2
(Springer-Verlag Italia Srl, 2016)In this paper, we study generalized pseudo null Bertrand curves in semi-Euclidean 4-space E-2(4) with index 2. We get the necessary and sufficient conditions for pseudo null curves to be generalized Bertrand curves and we ... -
Characterizations of Geometric and Discrete Pareto Distributions Based on the Conditional Distribution of kth Records
(Atlantis Press, 2016)The poblem of characterizing of discrete probability distributions is an important problem. Recently many new results are obtained in characterization of distributions using kth records. Based on the distributional properties ... -
Genetic and environmental influences on adult human height across birth cohorts from 1886 to 1994
(Elife Sciences Publications Ltd, 2016)Human height variation is determined by genetic and environmental factors, but it remains unclear whether their influences differ across birth-year cohorts. We conducted an individual-based pooled analysis of 40 twin cohorts ... -
Using of fractional factorial design (rk-p) in data envelopment analysis to selection of outputs and inputs
(Hacettepe Univ, Fac Sci, 2015)Data envelopment analysis (DEA) is a linear programming based technique for measuring the relative performance of organisational units where the presence of multiple inputs and outputs makes comparisons difficult. We used, ... -
The CODATwins Project: The Cohort Description of Collaborative Project of Development of Anthropometrical Measures in Twins to Study Macro-Environmental Variation in Genetic and Environmental Effects on Anthropometric Traits
(Cambridge Univ Press, 2015)For over 100 years, the genetics of human anthropometric traits has attracted scientific interest. In particular, height and body mass index (BMI, calculated as kg/m(2)) have been under intensive genetic research. However, ... -
