RNA polymerase II collision & its role in transcript elongation

Autor: Hobson, D. J.

Antisense non-coding transcripts, genes-within-genes, and convergent gene pairs are prevalent among eukaryotes. The existence of such transcription units raises the question of what happens when RNA polymerase II (RNAPII) molecules collide head-to-he

A unifying class of Skorokhod embeddings: connecting the Azema-Yor and Vallois embeddings

Autor: Cox, A. M. G., Hobson, D. G.

In this paper we consider the Skorokhod embedding problem in Brownian motion. In particular, we give a solution based on the local time at zero of a variably skewed Brownian motion related to the underlying Brownian motion. Special cases of the const

An Optimal Skorokhod Embedding for Diffusions

Autor: Cox, A. M. G., Hobson, D. G.

Given a Brownian motion $B_t$ and a general target law $\mu$ (not necessarily centered or even integrable) we show how to construct an embedding of $\mu$ in $B$. This embedding is an extension of an embedding due to Perkins, and is optimal in the sen
