Structure and formation of the lunar farside highlands.
The formation of the lunar farside highlands has long been an open problem in lunar science. We show that much of the topography and crustal thickness in this terrain can be described by a degree-2 harmonic. No other portion of the Moon exhibits comparable degree-2 structure. The quantified structure of the farside highlands unites them with the nearside and suggests a relation between lunar cr...
متن کاملSpectral Mapping of Mare Mosciviense, Lunar Farside, from Clementine Uvvis
Background: The Clementine mission provided the first high resolution mul-tispectral image data set of the far side of the Moon. While near side surface morphological units have been studied extensively from earth based spectral measurements, this is the first opportunity to examine the compositional properties of far side areas. Moscoviense is one of the prominent large impact basins on the lu...
متن کاملMechanisms of SN2 reactions: insights from a nearside/farside analysis.
A nearside/farside analysis of differential cross sections has been performed for the complex-forming SN2 reaction Cl(-) + CH3Br → ClCH3 + Br(-). It is shown that for low rotational quantum numbers a direct "nearside" reaction mechanism plays an important role and leads to anisotropic differential cross sections. For high rotational quantum numbers, indirect mechanisms via a long-lived intermed...
متن کاملNeuroendocrinology of amphibian metamorphosis.
The timing of metamorphosis is a central amphibian life history trait and is controlled by the interplay of developmental progression, body size and condition, and environmental signals. These different processes and signals are integrated by the neuroendocrine system to regulate production of hormones by the thyroid gland. Thyroid hormone (TH) is the primary morphogen controlling metamorphosis...
متن کاملAmphibian declines: future directions
The amphibian decline problem is complex, and there is no easy solution. I highlight four major areas of future research that should increase our ability to detect declines, elucidate their underlying mechanisms, and advance our capacity to manage and conserve amphibian populations. First, a statistically sensitive monitoring approach is necessary to determine the distribution and abundance of ...
