Mediation of the heliospheric termination shock by termination-shock-accelerated particles
AIP Conference Proceedings, 2010Energetic particle measurements made by Voyager 2 during its crossing of the heliospheric termination shock had distinctive features of a locally shock‐accelerated component in the energy range between 1 and 3.5 MeV. Intensities of energetic ions rose exponentially upstream of the shock and were accompanied by a deceleration of the bulk plasma flow ...

Shock Termination of Tachycardia
2020A 68-year-old man with ischemic cardiomyopathy (NYHA Class II, left-ventricular ejection fraction 26%) underwent implantation of a prophylactic dual-chamber ICD (Medtronic EnTrust™ D154ATG) 2 years ago. His medications include lisinopril 20 mg daily, carvedilol 12.5 mg daily, simvastatin 40 ms daily, and aspirin 325 mg daily. The ICD was programmed for

The recent Voyager 2 (V2) observations of the termination shock (TS) indicate that it is a plasma shock like no other in the heliosphere with dynamics and structure heavily influenced by the presence of an energized population of pickup ions (PUIs). The ‘unexpected’ finding of a cold plasma in the heliosheath with very little heating of the solar wind ...

An asymmetric solar wind termination shock
Nature, 2008Voyager 2 crossed the solar wind termination shock at 83.7 au in the southern hemisphere, approximately 10 au closer to the Sun than found by Voyager 1 in the north. This asymmetry could indicate an asymmetric pressure from an interstellar magnetic field, from transient-induced shock motion, or from the solar wind dynamic pressure.

In astrophysical settings, termination shocks where strong stellar wind outflows interact with the surrounding environments tend to take place in dusty regions. Just to name a few, star formation regions, planetary nebulae, supernova remnants and active galactic nuclei are all good examples.

We find that for reasonable choices of our parameters the compression ratio does not depart very much from the hydrodynamical value and stays between 3 and 4. If synchrotron electrons are produced via first order Fermi processes, then observations of spectral indices suggest compression ratios of about 4.

Multifractal Turbulence at the Termination Shock
AIP Conference Proceedings, 2010We consider the multifractal spectra of fluctuations of the interplanetary magnetic field strength before and after shock crossing by Voyager 1 near 85 and 95 AU from the Sun, correspondingly. We show that the multifractal scaling of magnetic fields is asymmetric in the outer heliosphere, in contrast to the symmetric spectrum observed in the ...

The solar wind shock termination
Advances in Space Research, 1986Abstract We analyse the possibility that the shock termination of the solar wind should occur at a heliocentric distance of 50 a.u. It is concluded that this is possible if the density of the interstellar medium near the Sun is of the order of 0.5 cm −3 , or the pressure of low energy cosmic rays (less than about 300 MeV/nucleon) is of the order of 6×

The termination shock: Physical processes
Advances in Space Research, 1995A brief overview of the physics thought to determine the properties of the heliospheric termination shock is given and the central role of hot interstellar pick-up ions and cosmic rays is emphasized.

Shock After Arrhythmia Termination
2020A 58-year-old male with a history of congestive heart failure and an ICD comes to clinic after receiving an ICD shock while mowing the lawn. The patient was not symptomatic during the episode. His left ventricular ejection fraction is 25% and he is being treated with appropriate medications including an angiotensin converting enzyme inhibitor and a ...
