[1] The eddy diffusion profile (K) in the auroral regions of Jupiter is not well determined. However, because of the intense auroral energy input, eddy mixing is expected to be much more effective and may be responsible for the enhancement of heavy hydrocarbon production in the polar region. In this paper, we estimate the increased eddy mixing in the Jovian auroral regions by comparing the Cass...

A definitive history of geomagnetism is yet to be written, but brief accounts have appeared in various publications. The story up to 1940 has been summarized (Chapman and Bartels, pp. 898-936). Perhaps the most complete account is by David R. Barraclough (pp. 584-592). Brief accounts have also been given by Stuart Malin (in Jacobs, ed., Geomagnetism, 1: 1-50), and others (Multhauf and Good, pp....

In the current article we present a fast and reliable algorithm for evaluating nth order pentadiagonal determinants in linear time. It is a natural generalization of the DETGTRI algorithm [M. El-Mikkawy, A fast algorithm for evaluating nth order tri-diagonal determinants, J. Comput. Appl. Math. 166 (2004) 581–584]. The algorithm is suited for implementation using computer algebra systems (CAS) ...
