Cluster data was used to examine the magnetospheric boundary and more particularly the tail. Harris sheet fits were done in a dynamic fashion that allows flapping to be quantified.

Selective predation (i.e., non-random feeding) was studied in a laboratory system that allowed individual lycosid spiders, Pardosa vancouveri. to feed on prey populations consisting of one or two kinds of insects. Various ...

This is a tutorial introducting polynomials of one or several variables. It discusses their degrees, their terms and the factoring of these terms.

Automated Forward Modeling (AFM) is an inversion technique based on magnetic data alone, which can indicate physical parameters associated with electrojets. From perturbations along a meridian, the total electric current ...

Jupiter’s Trojan asteroids fulfill the prediction of Lagrange that orbits can be stable when a small body orbits in specific locations relative to its ‘parent’ planet and the Sun. The first such Trojan asteroid was discovered ...
