Elastomeric gradients: a hedge against stress concentration in marine holdfasts?

Marine microbes see a sea of gradients.

Marine bacteria influence Earth's environmental dynamics in fundamental ways by controlling the biogeochemistry and productivity of the oceans. These large-scale consequences result from the combined effect of countless interactions occurring at the level of the individual cells. At these small scales, the ocean is surprisingly heterogeneous, and microbes experience an environment of pervasive ...

Are Building Materials Stocks a Hedge against Inflation in Nigeria

This paper investigates the extent to which stocks of Building materials firms listed in Nigerian Stock Exchange (NSE) are a hedge against the expected and unexpected inflation in Nigeria over the period 2000–2011. Unexpected inflation is computed as the difference between the actual inflation and the estimates of the expected inflation. The study used real rate of return on equity and regressi...

Restoring Predators as a Hedge against Climate Change

Climate change and the loss of ecologically relevant large terrestrial carnivore populations are two important challenges currently facing conservation practitioners (Ray et al. 2005, Sutherland et al. 2009). Little attention is given, however, to how these two problems might be related, and how mitigation eff orts for each might be united. Here we explain how predators cannot only infl uence t...

Using Hash Functions as a Hedge against Chosen Ciphertext Attack

The cryptosystem recently proposed by Cramer and Shoup [CS98] is a practical public key cryptosystem that is secure against adaptive chosen ciphertext attack provided the Decisional Diffie-Hellman assumption is true. Although this is a reasonable intractability assumption, it would be preferable to base a security proof on a weaker assumption, such as the Computational Diffie-Hellman assumption...
