Paradigm Shift between Turkey and the Kurds: From ‘Clash of the Titans’ to ‘Game of Thrones’
(Routledge, 2018-01-02)Throughout the history of the Turkish Republic, its military and political elites in Ankara have regarded the Kurdish question as a security issue. Therefore, initiating the ‘peace process’ with the PKK and developing ... -
Parametric study of multi-outputs T-junction spatial mode demultiplexers design with an objective-first algorithm
(SPIE, 2019)We design two different compact and low-loss 2D T-junction optical mode demultiplexing by using objective-first inverse design algorithm. These devices are designed for transverse-electric (TE) and transverse magnetic (TM), ... -
Parametric Study of Wavelength Demultiplexers Designed via Objective-First Algorithm
(SPIE, 2018-08)We demonstrate efficient and compact lxN wavelength-demultiplexing by using objective-first inverse design algorithm. Ultra-high device performances were achieved for the certain designs of 1x2, 1x3, and 1x4 demultiplexers ... -
Paraoxonase 1 (PON1) promoter (?107T/C) and coding region (192Q/R and 55L/M) genetic variations in pseudoexfoliation syndrome and pseudoexfoliative glaucoma risk
(Springer Berlin Heidelberg, 2019-10)Purpose: Pseudoexfoliation syndrome (PEX) is characterized by the accumulation of microscopic extracellular material in the anterior chamber of the eye and can lead to the development of pseudoexfoliative glaucoma (PEG) ... -
Parenchymal changes of salivary glands adjacent to a variety of salivary gland disorders
(E-CENTURY PUBLISHING CORP, 2019)A fully developed tumor is the first manifestation of a typical salivary gland neoplasm. Identification of precursor lesions and the accompanying clinical findings may improve our understanding of these tumors. The frequency ... -
Partial cloaking by graded index photonic crystals
(SPIE, 2014-04)Since the first proposal of the idea of optical cloaking, huge research effort has been spent to implement hiding objects. We propose a broad band all-dielectric partial (unidirectional) cloaking device that hides arbitrary ... -
