Cross-layer adaptive techniques for throughput enhancement in wireless OFDM-based networks
(2006)Although independent consideration of layers simplifies wireless system design, it is inadequate since: 1) it does not consider the effect of co-channel user interference on higher layers; 2) it does not address the impact ... -
Dexamethasone acutely accelerates pleural fluid absorption in mice hydrothoraces
(2010)This study assessed the effect of corticosteroid treatment in the clearance of hydrothoraces in mice. Twentyfour C57BL/6 mice were divided into four groups and were injected intrapleurally with 500 mu L sterilized PBS-BSA ... -
End corrections for rarefied gas flows through circular tubes of finite length
(2014)A method to take into account the influence of the inlet/outlet ends on rarefied gas flows through moderately long capillaries proposed previously [Vacuum 97, 26 (2013)] is applied to gas flows through circular tubes. The ... -
Insulin-Induced Electrophysiology Changes in Human Pleura Are Mediated via Its Receptor
(2010)Background. Insulin directly changes the sheep pleural electrophysiology. The aim of this study was to investigate whether insulin induces similar effects in human pleura, to clarify insulin receptor's involvement, and to ... -
A novel experimental setup for gas microflows
(2010)A new experimental setup for flow rate measurement of gases through microsystems is presented. Its principle is based on two complementary techniques, called droplet tracking method and constant-volume method. Experimental ... -
On Multicast Beamforming for Minimum Outage
(2009)The multicast beamforming problem is considered from the viewpoint of minimizing outage probability subject to a transmit power constraint. The main difference with the point-to-point transmit beamforming problem is that ... -
Performance of a laser Earth-to-satellite link over turbulence and beam wander using the modulated gamma-gamma irradiance distribution
(2011)We present an analytical framework for the performance evaluation of laser satellite uplinks over the major probabilistic impairments, i.e., atmospheric turbulence and beam wander. Specifically, we consider a ground-stat ... -
Ranolazine enhances nicardipine-induced relaxation of alpha1-adrenoceptor-mediated contraction on isolated rabbit aorta
(2015)Ranolazine (RAN) and nicardipine (NIC) have been studied for their vasorelaxing effects but the combination of these agents against adrenergic vasoconstriction has not been tested. The present study aimed at investigating ... -
Regulatory volume decrease of rat kidney principal cells after successive hypo-osmotic shocks
(2013)Outer Medullary Collecting Duct (OMCD) principal cells are exposed to significant changes of the extracellular osmolarity and thus the analysis of their regulatory volume decrease (RVD) function is of great importance in ... -
Role of Electrolytes and Glucose in the Insulin-Induced Electrochemical Effect in Sheep Pleura
(2010)Aim: Insulin induces electrochemical alterations in sheep visceral and parietal pleura, an effect abolished by the Na(+)-channel blocker amiloride and the Na(+)-K(+) pump inhibitor ouabain. The aim of this study was to ...
