Item Status of the Albanian Muslims in Greece During the Population Exchange on the Basis of the Minutes of Lausanne Conference and the Reports of the Embassy of Albania in Athens(2017) Ozcan, HalilThe Subcommittee of Population Exchange at Lausanne Conference addressed the exchange topic in twelve sessions between January, 11, 1923 and January 30, 1923. The convention and protocol concerning the exchange between populations of two countries were signed on January 30, 1923 by the Turkish and Greek Governments. Accordingly, it was decided to conduct compulsory population exchange between the "Turkish nationals of Greek Orthodox religion" who had domiciled in Turkish territories and the "Greek nationals of Muslim religion" who had domiciled in Greek territories. Despite Greece provided all assurances at Lausanne Conference and afterwards, it took action to exchange the Albanian Muslims, who lived in Epirus-Chameria region where almost all of the population was Muslim with the immigrant Greeks who came from Anatolia, due to the fact that the Albanian Muslims were "Greek nationals with Muslim religion." During this period, Mid'hat Frasheri was assigned to the Embassy of Albania in Athens on January 1923. The Ambassador discussed the situation of the Albanian Muslims in Greece, with the authorities, the League of Nations, the Mixed Exchange Committee, the Turkish authorities and mainly the Greek authorities. Mid'hat Frashri sent approximately 200 reports, which included these discussions to the Albanian Ministry of Foreign Affairs.Item Covering the More Visible Region by Electrochemical Copolymerization of Carbazole and Benzothiadiazole Based Donor-Acceptor Type Monomers(2019) Cansu-Ergun, Emine Gul; 0000-0002-3941-4345; I-7385-2017An electrochromic copolymer film of 2-(3,3-dihexyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepin-6-yl)-7-(3,3-dihexyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepin-8-yl)-9H-carbazole (M1) and 4,7-bis(thiophen-2-yl)benzo[c][1,2,5]thiadiazole (M2) was prepared via electrochemical technique. The copolymerization was performed with one to one monomer feed ratio. Electrochemical and optical properties of the resulting copolymer film (P3) and the homopolymer films of M1 and M2 (P1 and P2) were investigated by using cyclic voltammetry and UV-Vis spectrometry techniques, and the corresponding results were compared. Incorporation of M1 and M2 into copolymer matrix was clearly observed on the resulting cyclic voltammograms and UV-Vis spectra. P3 covered the visible regions coming from both P1 and P2, and exhibited a neutral state darker color than those of homopolymers. P3 film was found to have a multichromic behavior, appearing as brown in its neutral state while changing its color upon oxidation to dark-gray (at about 0.3 V), to blue (at about 0.6 V) and finally to grayish cyan (beyond 0.9 V), with a corresponding optical band gap of 1.65 eV.Item Pulse frequency fluctuations of magnetars(2019) Cerri-Serim, D.; Serim, M. M.; Sahiner, S.; Inam, S.C.; Baykal, A.; 0000-0003-0820-9186Using RXTE, Chandra, XMM-Newton and Swift observations, we construct the power spectra and torque noise strengths of magnetars for the first time. For some of the sources, on time-scales of months to years, we measure strong red noise that might be a consequence of their outbursts. We compare the noise strengths of magnetars with those of radio pulsars by investigating the possible correlations of noise strength with spin-down rate, magnetic field and age. Using these correlations, we find that the noise strengths of magnetars obey similar trends as radio pulsars. However, we do not find any correlation between noise strength and X-ray luminosity, a correlation that has been seen in accretion-powered pulsars. Our findings suggest that the noise behaviour of magnetars resembles that of radio pulsars, but magnetars possess higher noise levels likely because of their stronger magnetic fields.Item NUMERICAL STABILITY OF RBF APPROXIMATION FOR UNSTEADY MHD FLOW EQUATIONS(2019) Gurbuz, Merve; Tezer-Sezgin, M.In this study, the radial basis function (RBF) approximation is applied for solving the unsteady fluid flow and magnetohydrodynamic (MHD) convection flow problems with the use of explicit Euler time discretization and relaxation parameters to accelerate the convergence. The stability analysis is also carried out in terms of the spectral radius of related RBF discretized coefficient matrices. The optimal choices of the time increment, relaxation parameters and physical problem parameters are found for achieving stable solutions. It is observed that the maximum eigenvalues of the coefficient matrices decrease with an increase in the time increment when the relaxation parameters are decreasing. Although the time derivative is discretized using explicit Euler method, one does not need to use small time increment for obtaining stable results. The flow, isotherms and pressure behaviors are simulated at steady-state for several values of problem parameters using time increment and relaxation parameters which lead to stable solutions.Item A Deep LSTM Approach for Activity Recognition(2019) Guney, Selda; Erdas, Cagatay Berke; 0000-0002-0573-1326; 0000-0003-3467-9923; AAC-7404-2020Since 1990s, activity recognition effectual field in machine learning literature. Most of studies that relevant activity recognition, use feature extraction method to achieve higher classification performance. Moreover, these studies mostly use traditional machine learning algorithms for classification. In this paper, we focus on a deep (Long Short Term Memory) LSTM neural network for feature free classification of seven daily activities by using raw data that collected from three-dimensional accelerometer. Based on the results, the proposed deep LSTM approach can classify raw data with high performance. The results show that the proposed deep LSTM approach achieved 91.34, 96.91, 88.78, 87.58 as percent classification performance in terms of accuracy, sensitivity, specificity, F-measure respectively.Item Calibration transfer in temperature modulated gas sensor arrays(2016) Fernandez, L.; Güney, S.; Gutierrez-Galvez, A.; Marco, S.Shifts in working temperature are an important issue that prevents the successful transfer of calibration models from one chemical instrument to another. This effect is of special relevance when working with gas sensor arrays modulated in temperature. In this paper, we study the use of multivariate techniques to transfer the calibration model from a temperature modulated gas sensor array to another when a global change of temperature occurs. To do so, we built 12 identical master sensor arrays composed of three different types of commercial Figaro sensors and acquired a dataset of sensor responses to three pure substances (ethanol, acetone and butanone) dosed at 7 concentrations. The master arrays are then shifted in temperature (from -50 to 50 degrees C, Delta T = 10 degrees C) and considered as slave arrays. Data correction is performed for an increasing number of transfer samples with 4 different calibration transfer techniques: Direct Standardization, Piece-wise Direct Standardization, Orthogonal Signal Correction and Generalized Least Squares Weighting. In order to evaluate the performance of the calibration transfer, we compare the Root Mean Square Error of Prediction (RMSEP) of master and slave arrays, for each instrument correction. Best results are obtained from Piece-wise Direct standardization, which exhibits the lower RMSEP values after correction for the smaller number of transfer samples. (C) 2016 Elsevier B.V.

They have mostly androgenetic monospermic genomes with all the chromosomes originating from a haploid sperm and no maternal chromosomes. Androgenetic complete hydatidiform moles were described in 1977, but how they occur has remained an open question. We identified bi-allelic deleterious mutations in MEI1, TOP6BL/C11orf80, and REC114, with roles in meiotic double-strand breaks formation in women with recurrent androgenetic complete hydatidiform moles. We investigated the occurrence of androgenesis in Mei1-deficient female mice and discovered that 8% of their oocytes lose all their chromosomes by extruding them with the spindles into the first polar body. We demonstrate that Mei1−/− oocytes are capable of fertilization and 5% produce androgenetic zygotes. Thus, we uncover a meiotic abnormality in mammals and a mechanism for the genesis of androgenetic zygotes that is the extrusion of all maternal chromosomes and their spindles into the first polar body. © 2018 American Society of Human GeneticsItem Fetal HLA-G alleles and their effect on miscarriage(2018) Kubat, Gozde; Koc, Altug; Kirbiyik, Ozgur; Kutbay, Yasar B.; Ozyilmaz, Berk; Ozdemir, Taha R.; Kaya, Ozge Ozer; Koc, Zeynep Peker; 29809322Background. Immunosuppression at the feto-maternal interface is crucial for a successful pregnancy outcome. Human leukocyte antigen-G (HLA-G) seems to be a major contributor to fetal tolerance. The HLA-G expression is seen in cytotrophoblasts and in maternal blood. Fetal HLA-G acts on decidual antigen-presenting cells (APCs), natural killers (NKs) and T cells. Recent findings revealed that defects in placentation and their consequences are associated with maternal HLA-G variants and their expression levels. Objectives. The objective of this article is to investigate the relationship between fetal HLA-G alleles and miscarriage, which has not been investigated to date. Material and methods. The present study includes 204 recurrent miscarriage (RM) cases who were admitted to our clinic between 2012 and 2016. Twenty-eight miscarriage products without maternal cell contamination and any known pathology were analyzed by HLA-G typing. In addition, 3' untranslated region (UTR) 14-base pair (bp) insertion/deletion polymorphism was also investigated by Sanger sequencing. Results. For our population, the most frequent HLA-G type was G*01:01, both in the study group (30.3%) and in the control group (47%). The study revealed that the G*01:04 allele was significantly associated with miscarriage (p = 0.007). The 3' UTR 14bp deletion was more frequent in the miscarriage group, but there was no significant correlation. Conclusions. HLA-G alleles seem to be related with miscarriage and should be considered in RM cases.Item THE APPROACH OF ATATURK TO RELATIONS BETWEEN TURKEY AND ALBANIA BEFORE THE PROCLAMATION OF MONARCHY, IN THE LIGHT OF THE DIARIES OF RAUF FICO, THE MINISTER PLENIPOTENTIARY OF ANKARA(2018) Ozca, HalilThe diaries of RaufFico, Albanian Minister Plenipotentiary to Ankara, gives a lot of useful information about Albania-Turkey relations that had not been stumbled across in the literature until today. The aim of this study is to point out Atatiirk's views on relations between Albania and Turkey, Albania and Italy, as well as his suggestions to Albanian envoy in Ankara about how to overcome the Albanian dependency on Italy. The research is based on the diaries of Fico, Albanian Minister Plenipotentiary to Ankara. The study is limited with focusing on the Italian factor in Albania's relations with Turkey rather than examining all aspects of the relationship between the two independent countries. Fico had had formal education in the Ottoman Empire and occupied bureaucratic posts such as being provincial governor and following independence of Albania started to work for Albanian government as an important diplomat. Therefore, his diaries provide us a plenty of information on the question of Albania's relations with Turkey as well as with Italy, particularly between 1925 and 1928 during which there had been a Republican regime in Albania. In fact, Fico's diaries give perfect information about close relations between Turkey and Albania and the importance given by Mustafa Kemal Atatiirk on these relations at bilateral level, at least until the destruction of the Republican regime by Ahmet Zogu who would proclaim himself as the King of Albania in 1928. The content of the Fico's diaries are very rich in a way that they consist problems of Orthodox Albanians in Istanbul, positions of Albanians in Kosovo, the exchange of Albanian Chams, reforms in Turkey, assassination attempt to Atatirk in izmir and main themes in Nutuk. It should be kept in mind that the scope of this study is confined, first, to suggestions of Ataturk to the Albanian government regarding getting rid of dependency on Italy, and second, to his foresight about Italy's position towards Albania and Turkey. In this respect, the Fico's diaries give invaluable information on all these subjects elaborated in this paper.Item ÖZ DEĞERLENDİRMENİN 360 DERECE GERİ BESLEME YÖNTEMİNDEKİ İŞLEVSELLİĞİ(2012-06) Kubat, GözdeGünümüzde, insan faktörünün önemi işletmelerde uygulanan kalite çalışmaları kapsamında gittikçe artmaktadır.
