Pilot Symbol Aided Channel Estimation for Spatial Modulation-OFDM Systems and its Performance Analysis with Different Types of Interpolations
(Springer, 2017)
Spatial modulation orthogonal frequency division multiplexing (SM-OFDM) system has been recently proposed as an alternative for multiple-input multiple-output (MIMO)-OFDM systems to increase spectral efficiency by keeping ...
Reflection Modeling Based Broadband Matching Network Design
(Walter De Gruyter, 2017)
In this paper a new broadband matching network design approach based on reflection modeling is proposed which has two parts: impedance data generation and modeling. In the approach firstly the output impedance data of the ...
A Mobile Channel Model for VLC and Application to Adaptive System Design
(IEEE-INST Electrical Electronics Engineers Inc, 2017)
In this letter we propose a realistic channel model for visible light communication (VLC) assuming a mobile user. Based on non-sequential ray tracing we first obtain channel impulse responses for each point over the user ...
Which anesthetic agent alters the hemodynamic status during pediatric catheterization? Comparison of propofol versus ketamine
(W.B. Saunders Co Ltd, 2003)
Objective: To compare the effects of propofol and ketamine on systemic and pulmonary circulations in pediatric patients scheduled for elective cardiac catheterization. Design: Prospective randomized and blinded. Setting: ...
Corneal ring segments (INTACS) for the treatment of asymmetrical astigmatism of the keratoconus. Follow-up after 2 years
(Masson Editeur, 2003)
Objective: To evaluate the use of corneal ring segments (INTACS) for the treatment of asymmetrical astigmatism in keratoconus. Material and methods: This prospective study involved nine eyes of seven patients who were ...
Cognitive impairment in amyotrophic lateral sclerosis: evidence from neuropsychological investigation and event-related potentials
(Elsevier Science Bv, 2002)
The presence of subclinical cognitive impairment in patients with amyotrophic lateral sclerosis (ALS) is investigated using neuropsychological assessment and event-related potential recordings (ERP). An extensive battery ...
The role of oxygen saturation measurement and body mass index in distinguishing between non-apnoeic snorers and patients with obstructive sleep apnoea syndrome
(Blackwell Publishing Ltd, 2002)
The aim of this study was to examine the role of oxygen saturation (SaO(2)) measurement in identifying apnoeic snorers from non-apnoeic snorers and in the assessment of the severity of obstructive sleep apnoea. Ninety-two ...
Monostotic fibrous dysplasia of the clivus: MRI and CT findings
(Springer Verlag, 2002)
Fibrous dysplasia is a developmental disorder caused by abnormal proliferation and maturation of fibroblasts resulting in replacement of mature bone by structurally weak immature woven bone. Clival involvement in monostotic ...
Fault-tolerant training of neural networks in the presence of MOS transistor mismatches
(IEEE-INST Electrical Electronics Engineers Inc, 2001)
Analog techniques are desirable for hardware implementation of neural networks due to their numerous advantages such as small size low power and high speed. However these advantages are often offset by the difficulty in ...
Electrical activity regulates AChR gene expression via JNK PKC zeta and Sp1 in skeletal chick muscle
(Elsevier Science Bv, 2001)
Electrical activity of myotubes represses nicotinic acetylcholine receptor (AChR) gene expression. This effect is mimicked by okadaic acid and blocked by tetrodotoxin (TTX) or staurosporine in cultured myocytes [Altiok et ...
