Efficient discretization of stochastic integrals [PDF]
Finance and Stochastics, 2013 Sharp asymptotic lower bounds of the expected quadratic variation of discretization error in stochastic integration are given. The theory relies on inequalities for the kurtosis and skewness of a general random variable which are themselves seemingly new. Asymptotically efficient schemes which attain the lower bounds are constructed explicitly.

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with ageārelated morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Stochastic dynamic equations on general time scales
Electronic Journal of Differential Equations, 2013 In this article, we construct stochastic integral and stochastic differential equations on general time scales. We call these equations stochastic dynamic equations.

A Comparison of Stochastic Integrals
The Annals of Probability, 1979 the existence of the star integral, we give a formula relating the two integrals. We show that the star integral is equal to the dot integral provided one takes a projection of the integrand onto the space of predictable processes before evaluating the dot integral.

Discerning protein pools by selective staining with selfālabeling tags
FEBS Letters, EarlyView.Cell surface proteins have an intraā and extracellular pool. Combining genetic fusion to selfālabeling tags that can be addressed with small molecule fluorophores allows separating these pools. We highlight recent developments and techniques for stateāofātheāart interrogation of cell surface proteins in the complex tissue setting.

KarpatsŹ¹kƬ MatematiÄnƬ PublƬkacƬĆÆ, 2014 The operators of stochastic differentiation, which are closely related with the extended Skorohod stochastic integral and with the Hida stochastic derivative, play an important role in the classical (Gaussian) white noise analysis.

Golgi enzymes are retrieved from the plasma membrane to the transāGolgi network
FEBS Letters, EarlyView.Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the transāGolgi network via retrograde transport. Using a nanobodyābased toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.
