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 ... -
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 ... -
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 ... -
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 ... -
Novel Mutants of the Aubergine Gene
(Taylor & Francis Inc, 2016)Aubergine is an RNA-binding protein of the Piwi clade functioning in germline in the piRNA pathway that silences transposons and repetitive sequences. Several mutations of this gene exist but they mostly result in truncated ... -
A Novel Transmit Array Structure for Optical Spatial Modulation
(IEEE, 2019)The performance of multiple input single output (MISO) and multiple input multiple output (MIMO) systems is limited by spatial channel correlation. This limitation becomes particularly severe in light lidelity (LiFi) ... -
A numerical method for frequency determination in the astable cellular neural networks with opposite-sign templates
(IEEE, 2006)In this study a numerical method is proposed to determine the oscillation frequencies in the astable cellular neural networks with opposite-sign templates [1]. This method depends on the training of a multilayer perceptron ... -
A Numerical Study of Shallow Mixing Development over Flat Surface and Dunes
(TSINGHUA UNIV, 2013)Results of a high resolution Detached Eddy Simulation (DES) are used to characterize the evolution of a shallow mixing layer developing between two parallel streams in a long open channel with a smooth flat bed and dunes. ... -
A numerical study of the laminar necklace vortex system and its effect on the wake for a circular cylinder
(Amer Inst Physics, 2012)Large eddy simulation (LES) is used to investigate the structure of the laminar horseshoe vortex (HV) system and the dynamics of the necklace vortices as they fold around the base of a circular cylinder mounted on the flat ... -
Nutrient Dynamics in Flooded Wetlands. I: Model Development
(ASCE-AMER SOC CIVIL ENGINEERS, 2013)Wetlands are rich ecosystems recognized for ameliorating floods improving water quality and providing other ecosystem benefits. This part of a two-paper series presents a relatively detailed process-based model for nitrogen ... -
