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 ... -
Association of current and former smoking with body mass index: A study of smoking discordant twin pairs from 21 twin cohorts
(Public Library Science, 2018)Background Smokers tend to weigh less than never smokers, while successful quitting leads to an increase in body weight. Because smokers and non-smokers may differ in genetic and environmental family background, we analysed ... -
Bivariate Pseudo-Gompertz distribution and concomitants of its order statistics
(Elsevier Science Bv, 2013)This paper presents a new bivariate Pseudo-Gompertz distribution that sprouts from the classical Gompertz distribution and possesses the features of pseudo-distribution functions. In addition to some standard properties ... -
Block classical Gram-Schmidt-based block updating in low-rank matrix approximation
(Scientific Technical Research Council Turkey-Tubitak, 2018)Low-rank matrix approximations have recently gained broad popularity in scientific computing areas. They are used to extract correlations and remove noise from matrix-structured data with limited loss of information. ... -
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 ... -
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, ... -
The CODATwins Project: The Current Status and Recent Findings of COllaborative Project of Development of Anthropometrical Measures in Twins
(Cambridge Univ Press, 2019)The COllaborative project of Development of Anthropometrical measures in Twins (CODATwins) project is a large international collaborative effort to analyze individual-level phenotype data from twins in multiple cohorts ... -
Computational results on the compound binomial risk model with nonhomogeneous claim occurrences
(Elsevier Science Bv, 2014)The aim of this paper is to give a recursive formula for non-ruin (survival) probability when the claim occurrences are nonhomogeneous in the compound binomial risk model. We give recursive formulas for non-ruin (survival) ... -

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 ... -
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 ... -
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 ... -
Effects of different parameter estimators to error rate in discriminant analysis
(2018)Discriminant analysis is defined as a statistical technique that classifies a unit whose properties aremeasured, into one of the known finite numbers of populations. In this classifying process, an error occurswhen the ... -

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 ... -
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 ... -
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 influences on human height from infancy through adulthood at different levels of parental education
(NATURE RESEARCH, 2020)Genetic factors explain a major proportion of human height variation, but differences in mean stature have also been found between socio-economic categories suggesting a possible effect of environment. By utilizing a ... -
