Combined-Flow Model for Vertical Stratification Sequences in Shallow Marine Storm-Deposited Beds

Abstract: We develop a model to help explain the wide variety of vertical stratification sequences in shallow-marine sandstones This model, embodied in a set of vertical-sequence cartoons, predicts or accounts for vertical stratification sequences in beds of free sandstone deposited from a full range of decelerating combined flows, as well as from purely unidirectional and oscillatory flows According to the model, vertical stratification sequences in storm-deposited sandstone beds are the outcome of the time history of the bed configuration as deposition proceeds The idealized sequences are based on the initial velocities and subsequent deceleration histories of the unidirectional and oscillatory flow components Twenty qualitatively different sequences starting with plane bed are generated, and an additional 26 sequences result from omitting one or more of the lowermost intervals in succession The model thus accounts for 46 distinct kinds of sequences Five major simplifying assumptions are built into the model: bidirectional flows, linear deceleration of both unidirectional and oscillatory flow components, time-independent deposition rate, time-independent sediment size, and equilibrium bed configurations Owing to these assumptions, the model is likely to be applicable to only a small subset of vertical stratification sequences observed in shallow marine sandstones As more information on combined-flow bed configurations becomes available, these assumptions could be relaxed to provide a more refined and complete representation of vertical stratification sequences Since the model generates vertical sequences formed from any kind of decelerating flow, the Bouma sequence for deposits from purely unidirectional turbidity currents and also sequences resulting from decelerating purely oscillatory flows (similar in appearance to many proposed generalized tempestite sequences) are end-member cases in the model The model is also extended slightly to explain the geometry of the uppermost bedding surfaces of storm-generated sandstones by consideration of disequilibrium effects

Sources of Bank Interest Rate Risk

Abstract: We investigate bank stocks’sensitivity to changes in interest rates and the factors affecting this sensitivity. We focus on whether the exposure of commercial banks to interest rate risk is conditioned on certain balance sheet and income statement ratios. We find a significantly negative relation between bank stock returns and changes in interest rates over the period 1991–1996. We also find that bank characteristics measured from basic financial statement information explain bank stocks’sensitivity to interest rate changes. These results suggest that bank managers, analysts, and regulators can use this information to assess the relative risk exposure of banks.

System and method for conveting control flow graph representations to control-dataflow graph representations

Abstract: An embodiment of the invention includes a method of forming a control-dataflow graph that includes separating a control flow graph into two or more basic blocks, and converting said two or more basic blocks into code blocks, where the code blocks are formed into the control-dataflow graph. Another embodiment of the invention includes a method of forming a control-dataflow graph that includes separating a control flow graph into two or more basic blocks, forming a lode node in at least one of said basic blocks, forming a store node in at least one of said code blocks, inserting a delay node in at least one of said code blocks, segregating external hardware logic modules from said control flow graph, and converting said two or more basic blocks into code blocks, wherein the code blocks are formed into the control-dataflow graph.

Thrombectomy and soft debris removal device

Abstract: A device suitable for removing material from a living being is provided, featuring an infusate pump, and an aspiration pump, both powered by a motor. The aspiration pump and infusate pump preferably feature a helical pumping mechanism, and operate at a high rate of rotation, thereby ensuring adequate pumping performance and flexibility. Additionally, a narrow crossing profile is maintained, ensuring that the device may reach more tortuous regions of the vasculature.
