Estimating stochastic volatility diffusion using conditional moments of integrated volatility

Bollerslev, T; Zhou, H (Journal of Econometrics, 2002-07-01)

We exploit the distributional information contained in high-frequency intraday data in constructing a simple conditional moment estimator for stochastic volatility diffusions. The estimator is based on the analytical solutions ...

New insights into Hoogsteen base pairs in DNA duplexes from a structure-based survey.

Zhou, H; Hintze, BJ; Kimsey, IJ; Sathyamoorthy, B; Yang, S; Richardson, JS; Al-Hashimi, HM (Nucleic Acids Res, 2015-04-20)

Hoogsteen (HG) base pairs (bps) provide an alternative pairing geometry to Watson-Crick (WC) bps and can play unique functional roles in duplex DNA. Here, we use structural features unique to HG bps (syn purine base, HG ...

Rapid and efficient generation of transgene-free iPSC from a small volume of cryopreserved blood

Zhou, H; Martinez, H; Sun, B; Li, A; Zimmer, M; Katsanis, N; Davis, EE; ... (12 authors) (Stem Cell Reviews and Reports, 2015)

© The Author(s) 2015.Human peripheral blood and umbilical cord blood represent attractive sources of cells for reprogramming to induced pluripotent stem cells (iPSCs). However, to date, most of the blood-derived iPSCs were ...
