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...

We compare electron capture dissociation (ECD) of doubly protonated and divalent metal-adducted tyrosine O-sulfated peptides without basic amino acid residues. ECD of doubly protonated Tyr2-sulfated cholecystokinin (CCKS) and doubly protonated Tyr12-sulfated gastrin II (GST) resulted in complete loss of SO3 from all product ions. Thus, contrary to typical ECD behavior, localization of the sulfa...

Mutations in carbohydrate-negative mutants of Pseudomonas aeruginosa PAO1 individually deficient in glucose 6-phosphate dehydrogenase (zwf), 6-phosphogluconate dehydratase (edd), or pyruvate carboxylase (pyc) were mapped on the chromosome by plasmid R68.45-mediated conjugation and by bacteriophage F116L-mediated transduction. Loci for all three genes were located in the 45- to 55-min region of ...

The length of stay for moderately preterm infants has progressively become shorter in the UK in recent years but staff still commonly inform parents that their baby will go home around their estimated date of delivery (EDD). Parents need as much notice as possible to prepare for the discharge of their baby, and to gain the necessary skills and knowledge to care for their infant safely. We repor...
