In a typical multi-standard wireless communication receiver, the channelizer must have the capability of extracting multiple channels (frequency bands) of distinct bandwidths corresponding to different communication standards. The channelizer operates at the highest sampling rate in the digital front end of receiver and hence power efficient low complex architecture is required for costeffectiv...

In the most productive area of the Indo-Gangetic Plains in Northwest India where high yields of rice and wheat are commonplace, a medium-term cropping system trial was conducted in Haryana State. The goal of the study was to identify integrated management options for further improving productivity and profitability while rationalizing resource use and reducing environmental externalities (i.e.,...

In this study, we investigate the long-term exposure (20 weeks) to fumonisin B(1) (FB(1)) in grower-finisher pigs by conducting a quantitative exposure assessment (QEA). Our analytical approach involved both deterministic and semi-stochastic modeling for dietary comparative analyses of FB(1) exposures originating from genetically engineered Bacillus thuringiensis (Bt)-corn, conventional non-Bt ...

BACKGROUND Previous studies have demonstrated the safety of flexible bronchoscopy (FB) in mechanically ventilated subjects. However, the safety of FB in adult subjects receiving extracorporeal membrane oxygenation (ECMO) has not been described previously. METHODS A retrospective review was conducted of all adult subjects who underwent FB while receiving ECMO support at the University of Alaba...

Processing of visual information is performed in different cortical areas that are interconnected by feedforward (FF) and feedback (FB) pathways. Although FF and FB inputs are excitatory, their influences on pyramidal neurons also depend on the outputs of GABAergic neurons, which receive FF and FB inputs. Rat visual cortex contains at least three different families of GABAergic neurons that exp...

Fumonisin B(1) (FB(1)) is a mycotoxin produced by Fusarium verticillioides found on corn and corn-based foods. It causes equine leukoencephalomalacia, porcine pulmonary edema, and liver and kidney damage in most animal species. Fumonisin B(1) perturbs sphingolipid metabolism by inhibiting ceramide synthase activity, leading to the production of cell signaling factors including tumor necrosis fa...

I review the current status of lattice calculations of the properties of bound states containing one or more heavy quarks. Many of my remarks focus on the heavy-light leptonic decay constants, such as fB, for which the systematic errors have by now been quite well studied. I also discuss B-parameters, semileptonic form factors, and the heavy-light and heavy-heavy spectra. Some of my " world ave...

Background: Various methods have been described for safely performing fiberoptic bronchoscopy (FB) while applying non-invasive positive pressure ventilation (NIPPV) in patients with acute respiratory failure (ARF). Objectives: To evaluate the safety of a new method to perform FB in patients with ARF. Methods: Patients with ARF in whom FB was indicated were studied. The primary end-point was a m...
