New Trellis Code Design for Spatial Modulation
(IEEE-INST Electrical Electronics Engineers Inc, 2011)Spatial modulation (SM) in which multiple antennas are used to convey information besides the conventional M-ary signal constellations is a new multiple-input multiple-output (MIMO) transmission technique which has recently ... -
A new triazolothiadiazine derivative inhibits stemness and induces cell death in HCC by oxidative stress dependent JNK pathway activation
(Nature Portfolio, 2022)Hepatocellular carcinoma (HCC) is a highly heterogeneous cancer, and resistant to both conventional and targeted chemotherapy. Recently, nonsteroidal anti-inflammatory drugs (NSAIDs) have been shown to decrease the incidence ... -
News-Sharing Repertoires on Social Media in the Context of Networked Authoritarianism: The Case of Turkey
(USC ANNENBERG PRESS, 2020)Social media has become a primary gateway for users to access news, especially in authoritarian states with strictly controlled media environments. In such contexts, it is crucial to understand the motivations that prompt ... -
Next-Generation Multiple Access Based on NOMA With Power Level Modulation
(IEEE-Inst Electrical Electronics Engineers Inc, 2022)To cope with the explosive traffic growth expected in next-generation wireless networks, it is necessary to design next-generation multiple access techniques that can provide higher spectral efficiency as well as larger-scale ... -
Nexus between Sustainability Reporting and Firm Performance: Considering Industry Groups, Accounting, and Market Measures
(Mdpi, 2023)The relationship between Sustainability Reporting and corporate financial performance is overlapping and multifaceted and it has been an interesting issue for both academics and professionals since the beginning of the ... -
Nodal Sensitivity-Based Smart Inverter Control for Voltage Regulation in Distribution Feeder
(IEEE Electron Devices Society, 2021)Overvoltage is one of the issues in distribution grids with high penetration of photovoltaics (PVs). Centralized or droop-based methods of active power curtailment (APC) and/or reactive power control of PVs are viable ... -
Noise annoyance during COVID-19 lockdown: A research of public opinion before and during the pandemic
(Acoustical Society of America, 2020)Strict lockdown strategies to stop the spread of COVID-19 have caused a decrease in environmental noise levels and introduced new noise conditions in dwellings. The present study has investigated the impact of the forced ... -
NOMA-based Radio Resource Allocation for Machine Type Communications in 5G and Beyond Cellular Networks
(IEEE, 2021)In this paper, the minimum bandwidth resource allocation problem for non-orthogonal multiple access (NOMA) based machine to machine (M2M) communications in 5G and beyond cellular networks is investigated. In order to solve ... -
A non-communicating multi-robot system with switchable formations
(2013)We consider connected navigation of autonomous mobile robots with transitions in the group formation. The robots navigate using simple local steering rules without requiring explicit communication among themselves. The ... -
Non-Orthogonal Multiple Access for Terahertz Communication Networks
(IEEE, 2021)Terahertz communications is one of the promising technologies for the future mobile communication networks. Due to the ever increasing need for high-speed data transfer, higher bandwidths are required. As a solution, higher ... -
Noncoherent Ultra Wideband Wireless Sensor Networks for Primary User Detection
(IEEE Computer Society, 2016)As a result of increasing demand for new technologies unlicensed usage of available spectrum has become very essential to provide an efficient usage of spectrum. For that reason sensor networks may be a reliable option to ... -
Nondata-aided joint channel estimation and equalization for OFDM systems in very rapidly varying mobile channels
(IEEE-INST Electrical Electronics Engineers Inc, 2012)This paper is concerned with the challenging and timely problem of joint channel estimation and equalization for orthogonal frequency division multiplexing (OFDM) systems in the presence of frequency selective and very ... -
Nonlinear time series analysis of palaeoclimate proxy records
(Pergamon-Elsevier Science Ltd, 2021)Identifying and characterising dynamical regime shifts, critical transitions or potential tipping points in palaeoclimate time series is relevant for improving the understanding of often highly nonlinear Earth system ... -
The not so new Turkish woman: A statistical look at women in two Istanbul neighborhoods
(2009)Using survey data gathered from nearly 400 women living in two Istanbul neighborhoods this article explores issues of work education family and feminism. In addition to presenting the findings we argue that there is a ... -
A note on stock market response to elections in the post-communist countries of the European Union
(Routledge Journals, Taylor & Francis Ltd, 2023)We examine the stock market response to parliamentary elections in post-communist countries of the European Union. We document that the long-term market response to an election is -200 basis points (bps). The response is ... -
Novel 1,2,4-triazoles derived from Ibuprofen: synthesis and in vitro evaluation of their mPGES-1 inhibitory and antiproliferative activity
(Springer, 2022)Some novel triazole-bearing ketone and oxime derivatives were synthesized from Ibuprofen. In vitro cytotoxic activities of all synthesized molecules against five cancer lines (human breast cancer MCF-7, human lung cancer ... -
