Exploiting fine-grained parallelism through a combination of hardware and software techniques

Stephen Melvin, Yale Patt
1991 Proceedings of the 18th annual international symposium on Computer architecture - ISCA '91  
However, as the number of simultaneous operations increases, it beeomes possible to achieve speedups of three to six on realistic processors.  ...  In this paper we show that contrary to this notion, there is actually a significant amount of unexploited parallelism in typical general purpose code.  ...  The solution is to allow i] larger unit of work to be packed into the set of nodes issued as a unit. In this way, the machine does not starve due to not being able to get enough work into it.  ...

Life-Cycle Prices and Production

Mark Aguiar, Erik Hurst
2007 The American Economic Review  
For identical goods, prices paid are highest for middleaged, rich, and large households, consistent with the hypothesis that shopping intensity is low when the cost of time is high.  ...  We find an elasticity of substitution between time and market goods in home production of close to 2.  ...  The higher price for a specific UPC good at such a store may be the result of better store amenities. However, the nature of the data suggests that this is not an issue.  ...

Enforced Development Of The Earth's Atmosphere [article]

M. Iudin
2010 arXiv   pre-print
We review some basic issues of the life-prescribed development of the Earth's system and the Earth's atmosphere and discourse the unity of Earth's type of life in physical and transcendental divisions.  ...  Analysis of the coupling phenomena of elaborated ozone-oxygen transformation and Arctic bromine explosion is provided. Sensing is a foundation of life and the Earth's life.  ...  Complexity of biogeochemical cycling in everyday-world biotic Earth is intrinsically linked to the multiplicity of time scales and fractional topology.  ...

Cattle cycles, heterogeneous expectations and the age distribution of capital

David Aadland
2004 Journal of Economic Dynamics and Control  
Focusing solely on several major macroeconomic shocks, I also show that the model is capable of matching the timing and amplitude of the U.S. cattle cycle. JEL Codes: C61, Q11 and Q12.  ...  The theoretical model improves on existing models by (1) keeping track of the age distribution of the capital stock, (2) allowing for heterogeneous expectations, and (3) recognizing that cow-calf operators  ...  This is not for lack of trying but due to the complexity of the problem." RMS come the closest. However, their apparent excellent fit to the U.S. cattle cycle is somewhat overstated.  ...

Anfinsen showed that the amino acid sequence alone is sufficient to determine a protein's structure, but the molecular mechanism responsible for self-assembly remains an open question, probably the most  ...  Then, under folding conditions, the resultant fold is selected from a limited repertoire of structural possibilities, each corresponding to a distinct hydrogen-bonded arrangement of ␣-helices and͞or strands  ...  G.D.R. dedicates this perspective to Carl Frieden on the occasion of his symposium at 77: a restless intellect, a gentle heart, a cherished friend.  ...
