This paper details the application of a genetic programming framework for induction of useful classification rules from a database of income statements, balance sheets, and cash flow statements for North American public companies. Potentially interesting classification rules are discovered. Anomalies in the discovery process merit further investigation of the application of genetic programming ...

Ice flow models typically assume that ice is incompressible, a reasonable assumption because density changes are indeed small and have correspondingly effect on the overall mass balance of glaciers sheets. Given immense volume sheets, however, even relatively may influence global mean sea level to degree severely impacts humanity (Hauer others, 2020). Here, we quantify role gravitational compre...

Introduction: Deposits on the flanks of the large Tharsis Montes volcanoes (Arsia, Pavonis, and Ascraeus Mons) have been recognized to be of glacial origin [1,2]. These Amazonian-aged deposits display three distinct facies, ridged, knobby, and smooth [3], each of which can be associated with different glacial processes [1]. The outermost ridged facies is thought to be the imprint of ice-margin ...

We describe a concept for a spaceborne radar system designed to measure the surface and basal topography of terrestrial ice sheets and to determine the physical properties of the glacier bed. Our primary objective is to develop this new technology for obtaining spaceborne estimates of the thickness of the polar ice sheets with an ultimate goal of providing essential information to modelers esti...

We have studied the effect of the oxidation path and the mechanical energy input on the size of graphene oxide sheets derived from graphite oxide. The cross-planar oxidation of graphite from the (0002) plane results in periodic cracking of the uppermost graphene oxide layer, limiting its lateral dimension to less than 30 μm. We use an energy balance between the elastic strain energy associated ...

Since the mid-Pleistocene transition, deglaciation has occurred only after ice sheets have grown large while experiencing several precession and obliquity cycles, indicating that large ice sheets are more sensitive to Milankovitch forcing than small ice sheets are. Observations and model simulations suggest that the development of ice streams in the Laurentide Ice Sheet played an as yet unknown...

A simple quasi-analytical model is developed to study the response of ice-sheets to climate change. The model is axi-symmetrical and rests on a bed with a constant slope. The mechanics are highly parameterised. The climatic conditions are represented by the altitude of the runoff line. Above the runoff line the accumulation rate is constant (but may depend on, for instance, the ice-sheet size),...

Exploring the functioning of internal capital markets in financial conglomerates, this paper conducts a novel test of the credit channel of monetary policy. We look at how the response of lending to monetary policy shocks differs across small banks that are affiliated with the same bank holding company but that operate in distinct geographical areas. These subsidiaries tap into the same pool of...
