Good Volatility, Bad Volatility and Option Pricing [PDF]
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

THE FRACTIONAL VOLATILITY MODEL AND ROUGH VOLATILITY
The question of the volatility roughness is interpreted in the framework of a data-reconstructed fractional volatility model, where volatility is driven by fractional noise. Some examples are worked out and, using the Malliavin calculus for fractional processes, an option pricing equation and its solution are obtained.

Formation of reactive nitrogen species promoted by iron ions through the photochemistry of a neonicotinoid insecticide [PDF]
Nitrous 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.

Stochastic Volatility of Volatility in Continuous Time
This paper introduces the concept of stochastic volatility of volatility in continuous time and, hence, extends standard stochastic volatility (SV) models to allow for an additional source of randomness associated with greater variability in the data.

Volatility of Aggregate Volatility and Hedge Fund Returns [PDF]
This paper investigates empirically whether uncertainty about equity market volatility can explain hedge fund performance both in the cross section and over time. We measure uncertainty via volatility of aggregate volatility (VOV) and construct an investable version through returns on lookback straddles on the VIX index.
