The Influence of Ionizing Radiation on Quantification for In Situ and Operando Liquid‐Phase Electron Microscopy

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
Liquid‐phase transmission electron microscopy enables visualization of nanoscale processes involving liquid media. Yet, it suffers from beam effects, such as radiolysis of the liquid, sample heating, and membrane charging. This review summarizes beam effect fundamentals, describes modeling and assessment, and illustrates handling strategies.

Perfect hedging in rough Heston models [PDF]

open access: yesarXiv, 2017
Rough volatility models are known to reproduce the behavior of historical volatility data while at the same time fitting the volatility surface remarkably well, with very few parameters. However, managing the risks of derivatives under rough volatility can be intricate since the dynamics involve fractional Brownian motion.

On the pricing of forward starting options under stochastic volatility [PDF]

open access: yes, 2003
We consider the problem of pricing European forward starting options in the presence of stochastic ­volatility. By performing a change of measure using the asset price at the time of strike determination as a numeraire, we derive a closed-form solution based on Heston’s model of stochastic volatility.

Filtering and identification of stochastic volatility for parabolic type factor models [PDF]

open access: yes, 2006
We consider the dynamics of forward rate process which is modeled by a parabolic type infinite-dimensional factor model with stochastic volatility. The parameters included in the stochastic volatility dynamics are estimated from the factor process as the
