Conference Object Evolution of Binaries Towards Hmxbs and Lmxbs(American Institute of Physics, 2011) Kalomeni, BelindaIn this study we investigate the evolution of binary systems towards low mass x-ray binaries and high mass x-ray binaries using Eggleton's binary star evolution code. © 2011 American Institute of Physics.Conference Object Magnetic Cataclysmic Variables(American Institute of Physics, 2010) Kalomeni, BelindaWe present a study on magnetic cataclysmic variables (polars) using the collected data from the literature. These parameters (mass, radius, magnetic field intensity, mass transfer rate, etc.) and the relations between them are important to understand their nature, to explain the observed properties of them and to test the current evolutionary models. © 2010 American Institute of Physics.Conference Object Phenomenological Aspects of U(1)' Models(American Institute of Physics, 2009) Demir, Durmuş AliThis talk summarizes certain phenomenological aspects of the supersymmetric models with an extra U(1) invariance broken at the TeV scale. The discussions involve the Higgs sector, CP violation, Neutrino masses and the LHC signatures.Conference Object Signatures of Doubly-Charged Higgsinos at Colliders(American Institute of Physics, 2008) Demir, Durmuş Ali; Frank, Mariana; Huitu, Katri; Rai, Santosh Kumar; Turan, İsmailSeveral supersymmetric models with extended gauge structures predict light doubly-charged Higgsinos. Their distinctive signature at the large hadron collider is highlighted by studying its production and decay characteristics.Conference Object Citation - WoS: 1Dependence of Josephson Junction Critical Current on the Deposition Rate of Yba2cu3o7-? Thin Films(American Institute of Physics, 2007) Algül, B. P.; Avcı, İlbeyi; Akram, R.; Bozbey, Ali; Tepe, Mustafa; Abukay, DoğanWe have reported the effect of YBa2Cu3O 7-δ (YBCO) thin film deposition rate on the 24 and 30 degree STO bicrystal Josephson junctions critical currents by fabricating series of junctions with different deposition rates. Dependence of YBCO thin film structures on the deposition rate was investigated. We have observed that the critical currents of junctions are strongly affected by the thin film deposition rate.Conference Object Growth and Characterization of Carbon Nanostructures(American Institute of Physics, 2007) Selamet, Yusuf; Yüce, GörkemCarbon nanostructures were grown by arc-discharge method and characterized by SEM, AFM, STM, and XRD techniques. We observe broadening in the radial distribution of nanofibers grown with Co and Ni application. The nanofibers grown with Co/Ni application were straighter and shorter in length than nanofibers without Co/Ni application. This might be due to catalyst particle poisoning resulting in termination of the growth process earlier than expected.
