Large‐amplitude Alfvén waves in the interplanetary medium, 2

JW Belcher, L Davis Jr - Journal of Geophysical Research, 1971 - Wiley Online Library
An extensive study of the dynamic nonshock properties of the microscale fluctuations (scale
lengths of 0.01 AU and less) in the interplanetary medium was made by using plasma and …

Hemolysis and free hemoglobin revisited: exploring hemoglobin and hemin scavengers as a novel class of therapeutic proteins

…, PW Buehler, AI Alayash, JD Belcher… - Blood, The Journal …, 2013 - ashpublications.org
Hemolysis occurs in many hematologic and nonhematologic diseases. Extracellular

Cool heliosheath plasma and deceleration of the upstream solar wind at the termination shock

JD Richardson, JC Kasper, C Wang, JW Belcher… - Nature, 2008 - nature.com
The solar wind blows outward from the Sun and forms a bubble of solar material in the
interstellar medium. The termination shock occurs where the solar wind changes from being …

Activated monocytes in sickle cell disease: potential role in the activation of vascular endothelium and vaso-occlusion

JD Belcher, PH Marker, JP Weber… - Blood, The Journal …, 2000 - ashpublications.org
Sickle cell anemia is characterized by painful vaso-occlusive crises. It is hypothesized that
monocytes are activated in sickle cell disease and can enhance vaso-occlusion by activating …
