New pyrazoline bearing 4(3H)-quinazolinone inhibitors of monoamine oxidase: Synthesis biological evaluation and structural determinants of MAO-A and MAO-B selectivity
(Pergamon-Elsevier Science Ltd, 2009)A new series of pyrazoline derivatives were prepared starting from a quinazolinone ring and evaluated for antidepressant anxiogenic and MAO-A and -B inhibitory activities by in vivo and in vitro tests respectively. Most ... -
A New Technique for OFDM: OFDM-Index Modulation
(IEEE, 2013)In this study a novel scheme called orthogonal frequency division multiplexing with index modulation (OFDMIM) is proposed for frequency selective channels. In this scheme the information is conveyed not only by only M -ary ... -

(Wiley, 2019)[Abstract Not Available] -
A new thiadiazine derivative induces oxidative stress dependent JNK pathway activation and cell death in hepatocellular carcinoma
(Amer Assoc Cancer Research,, 2019)[Abstract Not Available] -
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 ... -
NİTEL DÜŞÜNCE VE ETNOGRAFİ: ETNOGRAFİK YÖNTEME DÜŞÜNSEL BİR YAKLAŞIM
(Hacettepe Üniversitesi İletişim Fakültesi, 2017)Bu yazıda niteliksel düşüncenin ne olduğunu, nereden kaynaklandığını ve etnografi ile olan ilişkisini irdelemeye çalışacağım. “Bilgi”yi öznenin nesne ile kurduğu bağın ürünü olarak kabul edersek, amacım, öznenin, yani ... -
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 ... -
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-preemptive priority scheduler with multiple thresholds for network routers
(Pamukkale Univ, 2018)The vast variety of applications available and being developed for computer networks have different quality of service requirements. One of the most significant ways to satisfy the needs of the applications is the packet ... -
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 ... -
Nonuniform sampling for detection of abrupt changes
(Birkhauser Boston Inc, 2003)In this work detection of abrupt changes in continuous-time linear stochastic systems and selection of the sampling interval to improve the detection performance are considered. Cost functions are proposed to optimize both ... -
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 ... -
Novel Application Software for the Semi-Automated Analysis of Infrared Meibography Images
(2019)Purpose: To develop semi-automated application software that quickly analyzes infrared meibography images taken with the CSO Sirius Topographer (CSO, Italy) and to compare them to the manual analysis system on the device ... -
A Novel Approach for Voltage Control in Electrical Power Distribution Systems
(IEEE, 2018)This paper proposes a novel approach for voltage control in 3-phase unbalanced distribution systems. The approach is based on the change of the magnetizing reactances of the voltage regulators in the system. We used an ... -
Novel Channel Models For Visible Light Communications
(Spie-Int Soc Optical Engineering, 2015)In this paper we investigate channel modeling for visible light communications (VLC) using non-sequential ray tracing simulation tools. We create three dimensional realistic simulation environments to depict indoor scenarios ... -
A novel hybrid approach for sentiment classification of TURKISH tweets for GSM operators
(North Atlantic University Union, 2018)The increase in the amount of content shared on social media makes it difficult to extract meaningful information from scientific studies. Accordingly in recent years researchers have been working extensively on sentiment ... -
A Novel Image Steganography Technique based on Similarity of Bits Pairs
(IEEE, 2017)Steganography is one of the most important information hiding mechanism which can be used along with cryptography for providing adequate data security. The common Steganographic mediums used are text image audio and video ... -
A Novel Indoor Channel Model for TVWS Communications based on Measurements
(IEEE, 2018)In this paper we present an indoor measurement campaign for TV white space bands inside a university building. The measurement results are compared with different indoor propagation models in the literature. We observed ...
