Skewed brownian fluctuations in single-molecule magnetic tweezers. [PDF]

open access: yesPLoS ONE, 2014
Measurements in magnetic tweezers rely upon precise determination of the position of a magnetic microsphere. Fluctuations in the position due to Brownian motion allows calculation of the applied force, enabling deduction of the force-extension response ...

A Simulation-Based Study on Bayesian Estimators for the Skew Brownian Motion

open access: yesEntropy, 2016
In analyzing a temporal data set from a continuous variable, diffusion processes can be suitable under certain conditions, depending on the distribution of increments.

A Solution to the Time-Scale Fractional Puzzle in the Implied Volatility

open access: yesFractal and Fractional, 2017
In the option pricing literature, it is well known that (i) the decrease in the smile amplitude is much slower than the standard stochastic volatility models and (ii) the term structure of the at-the-money volatility skew is approximated by a power-law ...

On Tightness of the Skew Random Walks

open access: yesJournal of Probability and Statistics, 2012
The primary purpose of this paper is to prove a tightness of 𝛼-skew random walks. The tightness result implies, in particular, that the 𝛼-skew Brownian motion can be constructed as the scaling limit of such random walks.
