In this paper, flip bifurcations of homoclinic orbits in conservative reversible systems are analysed. In such systems, orbit-flip and inclination-flip bifurcations occur simultaneously. It is shown that multi-pulses either do not bifurcate at all at flip bifurcation points or else bifurcate simultaneously to both sides of the bifurcation point. An application to a fifth-order model of water wa...

We present a review of the development of long-period fiber grating devices for application in optical communication. The recent studies on the realization of long-period gratings in optical planar waveguides are also highlighted.

There is considerable lay discussion that children with attention deficit hyperactivity disorder (ADHD) have increased difficulty with multitasking, but there are few experimental data. In the current study, we examine the simultaneous processing of two stimulus-response tasks using the Psychological Refractory Period (PRP) effect. We hypothesized that children with ADHD would show a greater PR...

Recent imaging campaigns indicate the likely existence of massive planets (∼ 1− 10 MJ ) on ∼> 1000 year orbits about a few percent of stars. Such objects are not easily explained in most current planet formation models. In this Letter we use ensembles of 100 N-body simulations to evaluate the potential for planet scattering during relaxation of dynamically active systems to explain the populati...

Dating from the late 1960s, coronary artery bypass grafting (CABG) remained a standard practice for a good 30 years. Percutaneous approaches came along halfway through that period, but the CABG operation did not change much. The widespread adoption of the internal thoracic artery (ITA) conduit to supply the left anterior descending coronary artery was the most significant modification, but was ...

ABSTRACT A set (n = 37) of new human bone radiocarbon accelerator mass spectrometry ( 14 C AMS) dates from 11 Lithuanian Late Roman Period–Migration Period cemeteries is presented and discussed in the light established schemes archaeological chronology. The focus paper on burials military social elite, which indicate emergence cultural traditions E–S W–Central Lithuania or immigration that took...
