Curvilinear Structure Enhancement in Biomedical Images

Curvilinear structures can appear in many different areas and at a variety of scales. They can be axons and dendrites in the brain, blood vessels in the fundus, streets, rivers or fractures in buildings, and others. So, it is essential to study curvilinear structures in many fields such as neuroscience, biology, and cartography regarding image processing. Image processing is an important field for the help to aid in biomedical imaging especially the diagnosing the disease. Image enhancement is the early step of image analysis. In this thesis, I focus on the research, development, implementation, and validation of 2D and 3D curvilinear structure enhancement methods, recently established. The proposed methods are based on phase congruency, mathematical morphology, and tensor representation concepts. First, I have introduced a 3D contrast independent phase congruency-based enhancement approach. The obtained results demonstrate the proposed approach is robust against the contrast variations in 3D biomedical images. Second, I have proposed a new mathematical morphology-based approach called the bowler-hat transform. In this approach, I have combined the mathematical morphology with a local tensor representation of curvilinear structures in images. The bowler-hat transform is shown to give better results than comparison methods on challenging data such as retinal/fundus images. The bowler-hat transform is shown to give better results than comparison methods on challenging data such as retinal/fundus images. Especially the proposed method is quite successful while enhancing of curvilinear structures at junctions. Finally, I have extended the bowler-hat approach to the 3D version to prove the applicability, reliability, and ability of it in 3D

Good news from Vienna is a relief to Ankara

After months of harrowing negotiations, the nuclear talks in Vienna have finally succeeded, marking the most significant accord between Iran and major world powers since Iran's Islamic revolution in 1979. Absent from the festivities, however, was one country that worked hard to bring this day forth—Turkey

Why Turkey chose, and then rejected, a Chinese air-defense missile

Mustafa Kibaroğlu (MEF Author)Ankara's decisions say a lot about what Turkey wants from the U.S. and NATO, if only the West will listen. When Turkey announced its intention to buy a Chinese missile system in 2013, many in the West believed Ankara was veering away from NATO. But look at that decision—and its recent reversal— through Turkish eyes, and the situation looks a lot different. Ultimately, the episode should teach its Western allies about what Turkey really wants, and doesn’t want

Business as usual: the U.S.-Turkey security partnership

The direction Turkey’s domestic politics has taken in recent years, Turkey’s aspira- tions for greater latitude in shaping region- al politics, and the incongruity of Turkey’s security interests with the policy objectives of its Western allies have all contributed to these troubles. Yet, the alarmists accusing Turkey of abandoning the West are em- bracing a one-sided and distorted narrative that further antagonizes Ankara and deepens the rift with its Western allies.The path to a robust alliance that can address the myriad challenges in the Middle East and beyond is a constructive dialogue between Turkey and its allies aimed at identifying the fulcrum that balances Turkey’s legitimate security interests with the broader objectives of its allies.WOS:000365814000008Scopus - Affiliation ID: 60105072Social Sciences Citation IndexQ3 - Q4ArticleUluslararası işbirliği ile yapılmayan - HAYIROcak2015YÖK - 2014-1

Umbilical Cord Serum Erythropoietin Levels and Maternal Smoking in Pregnancy

Objective. To evaluate the effect of maternal smoking during pregnancy on levels of umbilical cord erythropoietin. Methods. Erythropoietin levels were measured in umbilical cord sera of 60 newborns who were delivered vaginally at term. There were 20 (33%) smoking and 40 (67%) nonsmoking mothers. Results. Mean cord serum erythropoietin levels were significantly lower in the nonsmokers (nonsmokers, 24 ± 9 IU/L; smokers, 61 ± 46 IU/L; P < .001). There was a significant positive correlation between the number of cigarettes smoked per day and cord serum erythropoietin levels (r, 0.58; P ≤ .05). Conclusions. Smoking during pregnancy is associated with increased levels of umbilical cord erythropoietin at birth. This may indicate a risk of fetal hypoxia and growth restriction. Education and encouragement of cessation of smoking during pregnancy are important to avoid associated fetal and maternal morbidity and mortality

ELT instructors’ attitudes towards the use of Blended Learning in tertiary level English language programs

The aim of this study is to find the attitudes of language instructors towards blended learning at English Language Program of a foundation university, and to find out the nature of Schoology, a learning management system, for blended learning purposes. The participants were 35 English language instructors working at the foundation university in Turkey. A questionnaire developed by Moukali (2012) was used as a data collection tool in this study. The findings revealed that the English language instructors working for tertiary level English Language Program have a positive attitude towards blended learning. On the other hand, the opinions of the participants to make blended learning more successful in language teaching and learning environments were reflected comprehensively in the stud
