Adaptive OFDM-IM for enhancing physical layer security and spectral efficiency of future wireless networks
(Hindawi Limited, 2018)
In this paper, we propose algorithms for enhancing physical layer security and spectral efficiency of Orthogonal Frequency Division Multiplexing (OFDM) with Index Modulation (IM) systems. Particularly, different activation ...
Comparision of optical low coherence reflectometry versus ultrasonic biometry in high hypermetropia
(Lippincott Williams & Wilkins, 2018)
Purpose: To compare anterior chamber depth (ACD), axial length (AL), and lens thickness (LT) measurements obtained by the Lenstar LS 900 (Haag-Streit AG) optical low-coherence reflectometry with those obtained by the A-scan ...
A retrospective analysis of anaerobic bacteria isolated in 236 cases of pleural empyema and their prevalance of antimicrobial resistance in Turkey
(Clinical Laboratory Publ, 2018)
Background: Parapneumonic effusions usually occur secondary to an infection and produce pus (empyema) that accumulates in the pleural space. We aimed to evaluate the prevalence of anerobes in patients with empyema and to ...
Endobronchial ultrasound-guided transbronchial fine needle aspiration: Determinants of adequacy
(Bayçınar Medical Publishing, 2018)
Background: This study aims to evaluate the factors influencing the adequacy of endobronchial ultrasound-guided transbronchial fine needle aspiration specimens. Methods: A retrospective analysis of 1,700 endobronchial ...
Prediction and targeting of interaction interfaces in g-rotein coupled receptor oligomers
(Bentham Science Publishers Ltd, 2018)
Background: Communication within a protein complex is mediated by physical interactions made among the protomers. Evidence for both the allosteric regulation present among the protomers of the protein oligomer and of the ...
Comparison of SYNTAX score II efficacy with SYNTAX score and TIMI risk score for predicting in-hospital and long-term mortality in patients with ST segment elevation myocardial infarction
(Springer, 2018)
SYNTAX score II (SS-II) has a powerful prognostic accuracy in patients with stable complex coronary artery disease who have undergone revascularization; however, there is limited data regarding the prognosis of patients ...
External borrowing issue in Ottoman Empire (1854-1876 term)
(Springer, 2018)
By the beginning of the Nineteenth century, foreign borrowing was put on the agenda since it was understood that fiscal structure of the state could not be sustained by internal dynamics; yet, foreign borrowing did not ...
Beyond the therapeutic effect of RTMS in Alzheimer’s disease: A possible neuroprotective role of hippocampal BDNF?: A minireview
(Bentham Science Publishers B.V., 2018)
Repetitive transcranial magnetic stimulation (rTMS) is a well known non-invasive brain stimulation procedure which is capable of inducing the expression of the hippocampal BDNF that has been already shown to exert significant ...
Economic contributions of the Ottoman Bank in the Ottoman Empire and the Turkish Republic
(Springer, 2018)
The Ottoman Bank had a special place in the Ottoman Empire during the development of monetary and credit institutions. Founded in 1863, the Ottoman Bank functioned as the central bank for many subjects in the Ottoman Empire, ...
Secure spatial multiple access using directional modulation
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2018)
In this paper, we introduce a secure multiple access scheme, which exploits the multipath structure of the channel to create a multi-user interference environment. The generated interference enables legitimate users to ...
