Differentiation of Agaricus species and other homobasidiomycetes based on volatile production patterns using an electronic nose system [PDF]
, 2003 Comparisons of the qualitative volatile production patterns between seven species of Agaricus, and between two of Volvariella and Pleurotus and one Coprinus species when grown at 25°C on agar media for 14d were made.

Formation of reactive nitrogen species promoted by iron ions through the photochemistry of a neonicotinoid insecticide [PDF]
Atmospheric Chemistry and PhysicsNitrous acid (HONO) and nitrogen oxides (NOx=NO+NO2) are important atmospheric pollutants and key intermediates in the global nitrogen cycle, but their sources and formation mechanisms are still poorly understood.

Implications of non-volatile memory as primary storage for database management systems [PDF]
, 2017 Traditional Database Management System (DBMS) software relies on hard disks for storing relational data. Hard disks are cheap, persistent, and offer huge storage capacities. However, data retrieval latency for hard disks is extremely high.

Journal of Econometrics, 2011 The study of high-frequency financial data has been one of the most rapidly evolving areas of research over the last decade. We have seen an explosive growth in the availability of such data, which has gone hand in hand with the development of theory for how to analyze the data.

Good Volatility, Bad Volatility and Option Pricing [PDF]
SSRN Electronic Journal, 2016 Advances in variance analysis permit the splitting of the total quadratic variation of a jump-diffusion process into upside and downside components. Recent studies establish that this decomposition enhances volatility predictions and highlight the upside/downside variance spread as a driver of the asymmetry in stock price distributions. To appraise the

Current Biology, 2010 Plant volatiles are the metabolites that plants release into the air. The quantities released are not trivial. Almost one-fifth of the atmospheric CO2 fixed by land plants is released back into the air each day as volatiles. Plants are champion synthetic chemists; they take advantage of their anabolic prowess to produce volatiles, which they use to ...

SSRN Electronic Journal, 2014 Estimating volatility from recent high frequency data, we revisit the question of the smoothness of the volatility process. Our main result is that log-volatility behaves essentially as a fractional Brownian motion with Hurst exponent H of order 0.1, at any reasonable time scale.
