The RossiXTE mission provided us with an unprecedentedly large database of X-ray observations of transient black-hole candidates. These systems are crucial for the understanding of the physical properties of mass accretion onto black holes. Here I review the results on a selected sample of systems and describe their behavior in a purely phenomenological way. From these results, we can derive a ...

When transcription of a gene is induced by a stimulus, the number of its mRNA molecules changes with time. Here we discuss how this time evolution depends on the shape of the mRNA lifetime distribution. Analysis of the statistical properties of this change reveals transient effects on polysomes, ribosomal profiles, and rate of protein synthesis. Our studies reveal that transient phenomena in ge...

Many cardiac abnormalities are of a transient nature, creating a beat-to-beat variation in myocardial function. This work presents the cardiac imaging technique for the measurement of regional function during transient cardiac phenomena. All information necessary for the reconstruction of a cine loop is acquired within a single heartbeat, avoiding the temporal blurring introduced by segmented i...

Introduction: With recent interest in Transient Lunar Phenomena (TLP) and lunar out-gassing theories [1-3], the TLP catalogs of Middlehurst [4] and Cameron [5] are frequently quoted in references. However there are many issues that affect the quality of TLP reports and observer interpretation of the Moon’s surface, which may not be appreciated fully. Therefore as part of collaboration between A...

In recent years, computational electromagnetism has had a great development thanks to the computational systems speed increase and their cost reduction. With those improvements the mathematical algorithms are able to work properly with more practical EMC issues. The problem that arises many times is to become confident with the results, in other words, to be able to quantitatively validate the ...
