Distinguishing the epimers iduronic acid (IdoA) and glucuronic acid (GlcA) has been a long-standing challenge for the mass spectrometry analysis of glycosaminoglycan (GAG) oligosaccharides. In this work, electron detachment dissociation (EDD) and Fourier transform ion cyclotron resonance mass spectrometry is shown to provide mass spectral features that can distinguish GlcA from IdoA in heparan ...

Few data are available regarding the effects of exercise training upon cardiac structure and performance in man. We evaluated the echograms of 24 normals before (PRE) and after (POST) 11 weeks of endurance exercise training. Conditioning consisted of a walk-jog-run protocol at 70% maximal heart rate for one hour four days per week. Training reduced heart rate and increased maximal duration and ...

Structural characterization of glycosaminoglycans (GAGs) has been a challenge in the field of mass spectrometry, and the application of electron detachment dissociation (EDD) Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) has shown great promise to GAG oligosaccharide characterization in a single tandem mass spectrometry experiment. In this work, we apply the technique o...

Previous studies of the U.S. Great Depression find that increased government spending and taxation contributed little to either the dramatic downturn or the slow recovery. These studies include only one type of capital taxation: a business profits tax. The contribution is much greater when the analysis includes other types of capital taxes. A general equilibrium model extended to include taxes ...

The aim of the investigation was to off-line compare parameters of uterine EMG signals recorded during pregnancy in humans and sheep. Uterine corpus EMG recording sessions were performed in humans and in sheep. Sixty-five women underwent uterine corpus EMG recording sessions using abdominal surface skin electrodes. Six sheep underwent multiple EMG recording sessions using implanted electrodes. ...

The fixed antibacterial combination of ampicillin and sulbactam is frequently used for various infections. The normal kidneys eliminate approximately 60% of ampicillin (371.39 Da) and sulbactam (255.22 Da). Concomitant with the decline in renal function, the terminal elimination half-life increases from 1 up to 24 h in patients with ESRD. Patients on three times weekly low flux haemodialysis ex...

We evaluate the performance of scheme providing deterministic performance guarantees to real-time network clients with variable bit-rate (VBR) traac. We use long traces of video compressed using diierent algorithms for our analysis. The optimal scheduling algorithm EDD is used to carry out the analysis. Improved admission control tests for EDD scheduler are derived. We compare performance of th...

Many network applications that require Quality-ofService (QoS) support, such as transmission of digital voice and video, tolerate a certain level of service degradation. In this study, a novel network service, referred to as service with bounded degradation (BD service), is presented that can take advantage of the delay tolerance of applications. Di erent from previous proposals for similar ser...

The bulk of X-ray spectroscopic studies active galactic nuclei (AGN) are focused on local ($z < 0.1$) sources with low-to-moderate ($< 0.3$) Eddington ratio ($\lambda_\mathrm{Edd}$). It is then mandatory to overcome this limitation and improve our understanding highly accreting AGN. In work we present the preliminary results from analysis a sample $\sim70$ high-$\lambda_\mathrm{Edd}$ radio-quie...

An interesting feature in active galactic nuclei (AGN) accreting at low rate is the weakness of reflection features their X-ray spectra, which can result from gradual disappearance torus with decreasing accretion rates. It has been suggested that luminosity AGN (LLAGN) would have a different reflector configuration compared high AGN, either covering smaller fraction sky or simply having less ma...
