Ondansetron hydrochloride for the treatment of delirium after coronary artery surgery
(Mosby Inc, 2001)
[Abstract Not Available]
Space-time coded systems with joint transmit and receive antenna selection
(IEEE, 2007)
This paper studies performance of space-time coded (STC) systems with joint transmit and receive antenna selection over multiple input multiple output (MIMO) flat and frequency-selective (FS) fading channels. Specifically ...
Distributed estimation with channel estimation error over orthogonal fading channels
(IEEE, 2007)
We study distributed estimation of a source corrupted by an additive Gaussian noise and observed by sensors which are connected to a fusion center with unknown orthogonal (parallel) flat Rayleigh fading channels. The fading ...
Channel estimation for MIMO-OFDM systems in fixed broadband wireless applications
(IEEE, 2007)
Systems employing multiple transmit and receive antennas known as multiple input multiple output (MIMO) systems can be used with OFDM to improve the resistance to channel impairments. Thus the technologies of OFDM and MIMO ...
Blind-phase noise estimation in OFDM systems by sequential Monte Carlo method
(John Wiley and Sons Ltd, 2006)
One of the main drawbacks of orthogonal frequency division multiplexing (OFDM) systems is the phase noise (PN) caused by the oscillator instabilities. Unfortunately due to the PN the most valuable feature namely orthogonality ...
A true fundic diverticulum of the gallbladder
(Blackwell Publishing Ltd, 2006)
[Abstract Not Available]
A low-complexity time-domain MMSE channel estimator for space-time/frequency block-coded OFDM systems
(Hindawi Publishing Corporation, 2006)
Focusing on transmit diversity orthogonal frequency-division multiplexing (OFDM) transmission through frequency-selective channels this paper pursues a channel estimation approach in time domain for both space-frequency ...
Recurrent tuberculous pseudoaneurysm of the descending thoracic aorta - A case report
(WESTMINSTER PUBL INC, 2006)
Tuberculous pseudoaneurysm of the aorta is a rare disease that is uniformly fatal if not treated properly. The authors present a case of a recurrent tuberculous false aneurysm of the descending thoracic aorta that was ...
Performance of space-time coded systems with transmit antenna selection
(IEEE, 2007)
We deal with transmit antenna selection for space-time coded (STC) systems over multiple input multiple output (MIMO) channels. Using pairwise error probability analysis and simulation results we show that transmit antenna ...
A computational study on the amine-oxidation mechanism of monoamine oxidase: Insight into the polar nucleophilic mechanism
(Royal Soc Chemistry, 2006)
The proposed polar nucleophilic mechanism of MAO was investigated using quantum chemical calculations employing the semi-empirical PM3 method. In order to mimic the reaction at the enzyme's active site the reactions between ...
