The efficiency of conversion of precursor ions to observable products for electron detachment dissociation (EDD) was measured as a function of the key experimental parameters to determine their optimal values for the Fourier transform mass spectrometry analysis of anionic glycosaminoglycan carbohydrates. These parameters include electron current, electron energy, dispenser cathode heater curren...

Improving our understanding of the nuclear properties high-Eddington ratio ($\lambda_\mathrm{Edd}$) active galactic nuclei (AGN) is necessary since bulk X-ray spectroscopic studies have been focused on low-Eddington AGN. We present here spectral analysis 14 radio-quiet, $\lambda_\mathrm{Edd}\gtrsim1$ AGN at $0.4\leq z \leq 0.75$, observed with XMM-Newton. Optical/UV data from simultaneous Optic...

Accreting Black Holes (BHs) are believed to be sites of possible particle acceleration with favorable conditions also for effective gamma-ray production. However, because of photon-photon pair production, only low energy (MeV) gamma-rays can escape these compact objects with typically very large compactness parameter, κ = L L Edd Rg R ≥ 0.01, given that in most cases the accretion disks within ...

3C 216 has a weak accretion flow luminosity, well below the Seyfert1/QSO dividing line, weak broad emission lines (BELs) and powerful radio lobes. As a consequence of the extreme properties of 3C 216, it is the most convincing example known of an FR II radio source that is kinetically dominated: the jet kinetic luminosity, Q, is larger than the total thermal luminosity (IR to X-ray) of the accr...

The aim of this study was to investigate the endothelial dysfunction (ED) and carotid intima-media thickness (IMT) in patients with glycogen storage disease (GSD) types Ia and III. In 22 patients with GSD (13, type Ia; 9, type III) and 18 healthy subjects, endothelial functions of the brachial artery and carotid IMT were evaluated by high-resolution ultrasound. Endothelial-dependent dilatation ...

Sensor networks are composed of a number of sensor nodes with limited resources and used in application such as environment monitoring and object tracking. This allows a situation where the adversary can compromise one sensor node, fabricate many replicas having the same identity (ID) from the captured node, and place these replicas back into strategic positions in the network for further malic...
