Charged particle behavior in the growth and damping stages of ultralow frequency waves: Theory and Van Allen Probes observations
Download2016
Wygant, John R., Zong, Qui-Gang, Kletzing, Craig A., Blake, J. Bernard, Kivelson, Margaret G., Zhou, Xuzhi, Chen, Xing-Ran, Rankin, Robert, Wang, Zi-Han
Ultralow frequency (ULF) electromagnetic waves in Earth's magnetosphere can accelerate charged particles via a process called drift resonance. In the conventional drift resonance theory, a default assumption is that the wave growth rate is time independent, positive, and extremely small. However,...

Rankin, Robert , Degeling, Alex W., Watt, Clare E.
We introduce a new methodology that allows the construction of wave frequency distributions due to growing incoherent whistler-mode waves in the magnetosphere. The technique combines the equations of geometric optics (i.e., raytracing) with the equation of transfer of radiation in an anisotropic...

Deformation and evolution of solar wind discontinuities through their interactions with the Earth's bow shock
Download2009
Kabin, Konstantin, Keika, Kunihiro, Rankin, Robert, Carr, C. M., Carlson, C. W., Glassmeier, Karl-Heinz, Magnes, Werner, Lucek, Elizabeth, McFadden, J. P., Dandouras, Iannis, Auster, H. U., Sibeck, D. G., Fornacon, K.-H., Angelopoulos, Vassilis, Baumjohann, W., Nakamura, Rumi
The present study examines the interaction of solar wind discontinuities with the Earth's bow shock, using multipoint observations in the magnetosheath by Time History of Events and Macroscale Interactions During Substorms (THEMIS), Cluster, and Double Star TC1. We focus on the deformation and...

Rankin, Robert, Tikhonchuk, Vladimir T., Samson, John C.
Dispersive effects in field line resonances (FLRs) are discussed in the context of potential structures, parallel currents, and auroral density cavities observed by the FAST satellite. Our model includes the Earth's dipole magnetic field, and accounts for electron inertia, electron thermal...

Effects of phytase supplementation on performance and phosphorus excretion from broiler chickens fed low phosphorus-containing diets based on normal or low-phytic acid barley
Download2009-01-01
Thacker, Philip A., Haq, Inam, Willing, Benjamin P., Leytem, April B.
A total of 240 day-old broiler chicks were used to study the effects of phytase on performance and phosphorus (P) excretion from birds fed diets containing low phytate barleys formulated without inorganic P. A positive control based on Harrington barley (HB) was formulated to meet requirements...

Marchand, Richard, Lu, J. Y., Rankin, Robert, Solomon, Stanley C., Wang, Wenbin, Le, G. M., Wang, J. S., Lei, J., Rae, I. Johnathan
A new interactive M-I coupling model that describes the dynamic interaction between magnetospheric dispersive waves, compressional modes, and auroral electron precipitations is applied to investigate the geomagnetic electromagnetic pulsations observed in Earth's magnetosphere in terms of...

We investigate parallel electron acceleration due to inertial Alfven wave pulses in the presence of Lorentzian ( kappa) distribution functions which possess high-energy tails. A linear kinetic dispersion relation for inertial Alfven waves is derived whose solutions are used to guide the analysis...

Expression of cationic amino acid transporters, carcass traits, and performance of growing pigs fed low-protein amino acid-supplemented versus high protein diets
Download2013
Morales, Adriana, García, Hector, Araiza, Alfonso, Cervantes, Miriam, Grageola, Fernando, Zijlstra, Ruurd T.
Free amino acids (AA) appear to be absorbed faster than protein-bound AA (PB-AA). We conducted an experiment to assess the effect of feeding pigs with a partially free (F-AA) or totally PB-AA diet on expression of selected genes and performance of pigs. The expression of cationic AA transporters...

Hopkins, Daniel, Beard, Laura J.
In this article, we use examples from contemporary Anishinaabe artist Rebecca Belmore and the works of the Spiderwoman Theater Troupe to explore how contemporary Indigenous artists in the Americas negotiate the representation of Indigenous identities, identities which are always performed and...

Rankin, Robert, Ridley, Aaron J., Gombosi, Tamas I., Clauer, C. Robert, Watanabe, Masakazu, Kabin, Konstantin, Sofko, George J.
On the basis of magnetohydrodynamic simulation results for northward interplanetary magnetic field ( IMF) and significant dipole tilt, we describe internal reconnection processes that occur earthward of the magnetopause subsequent to magnetopause reconnection. We discuss the associated...
