Cardiac MR (CMR) imaging in a defined phase of the heart cycle requires triggered data acquisition. Systems with B0 up to 1.5 T utilize ECG signals for triggering. However, due to the increasing perturbing influence of the magneto-hydrodynamic effect on the ECG signal, triggering is additional hampered in high and ultrahigh field MRI systems. The necessity to attach ECG electrodes to the human ...

Antagonistic interactions between hosts and pathogens frequently result in arms races. The host attempts to recognise the pathogen and inhibit its growth and spread, whereas the pathogen tries to subvert recognition and suppress host responses. These antagonistic interactions drive the evolution of ‘decoys’ in both hosts and pathogens. In host–pathogen interactions, the term decoy describes mol...

The brightest giant flare from the soft γ-ray repeater (SGR) 1806-20 was detected on 2004 December 27. The isotropic-equivalent energy release of this burst is at least one order of magnitude more energetic than those of the two other SGR giant flares. Starting from about one week after the burst, a very bright (∼ 80 mJy), fading radio afterglow was detected. Follow-up observations revealed the...

In spite of growing need of synchronous electrophysiological and video measurements and analysis, there are no acquisition systems providing this function. Therefore we developed software providing unified user interface for synchronous electrophysiological and video acquisition and analysis and allowing triggering external devices and powerful Matlab interoperability. The software consists of ...

A Framework for developing Context-aware Systems Sofian Alsalman Hnaide In ubiquitous computing the environment constraints are often regarded as static and software applications are allowed to function in a mobile ecospace. However, in context-aware systems the environment attributes of software applications are dynamically changing. This dynamism of contexts must be accounted for in order to ...

Reactive arthritis (ReA) is a sterile arthritis triggered by distal mucosal infection, which suggests a contribution from bacterial products. The pathogenesis of ReA is unclear. There are no international standards for the serological methods used to confirm ReA. In the present work, we analyzed the predominant bacterial component that triggered an immune response in a 24-year-old woman with ac...

Activation of receptors by serotonin (5-HT1) and norepinephrine (α2) on primary afferent terminals and excitatory interneurons reduces transmission in spinal sensory pathways. Loss or reduction of descending sources of serotonin and norepinephrine after spinal cord injury (SCI) and the subsequent reduction of 5-HT1/α2 receptor activity contributes, in part, to the emergence of excessive motoneu...

1. Monkeys were trained to react to an arm perturbation according to an instruction delivered prior to the perturbation. There were two possible instructions (push or pull), and monkeys learned to respond accordingly regardless of the direction (push or pull) of the triggering perturbation. 2. Pyramidal tract neurons (PTNs) in contralateral motor cortex arm area responded to the triggering pert...

Many of the conditions that are necessary for starbursts appear to be important in the triggering of QSOs. However, it is still debatable whether starbursts are ubiquitously present in galaxies harboring QSOs. In this paper we review our current knowledge from observations of the role of starbursts in different types of QSOs. Post-starburst stellar populations are potentially present in the maj...
