Minimal nonergodic directions on genus 2 translation surfaces (2005)
It is well-known that on any Veech surface, the dynamics in any minimal direction is uniquely ergodic. In this paper it is shown that for any genus 2 translation surface which is not a Veech surface...
Slowly divergent geodesics in moduli space (2005)
Slowly divergent geodesics in the moduli space of Riemann surfaces of genus at least 2 are constructed via cyclic branched covers of the torus. Nonergodic examples (i.e. geodesics whose defining...
A divergent Teichmuller geodesic with uniquely ergodic vertical foliation (2005)
We construct an example of a quadratic differential whose vertical foliation is uniquely ergodic and such that the Teichmuller geodesic determined by the quadratic differential diverges in the moduli...
Serial assessment of left ventricular diastolic function after Fontan procedure
Cheung, Y, Penny, D, Redington, A
OBJECTIVE—To assess longitudinal changes in systemic ventricular diastolic function late after the Fontan procedure. DESIGN AND PATIENTS—Prospective study of 13 patients at 2.8 (2.0) years...
Relation of arterial stiffness with gestational age and birth weight
Cheung, Y, Wong, K, Lam, B., Tsoi, N
Background: The cardiovascular risk of individuals who are born small as a result of prematurity remains controversial. Given the previous findings of stiffer peripheral conduit arteries in growth...
Cheung, Y, Brogan, P, Pilla, C, Dillon, M, Redington, A
Background: Polyarteritis nodosa is a necrotising vasculitis of the medium sized and small muscular arteries. The inflammatory and subsequent reparative processes may alter the arterial mechanical...
Ultrasonographic findings and differentiation of benign and malignant focal splenic lesions
Wan, Y, Cheung, Y, Lui, K, Tseng, J, Lee, T
The purpose of this study was to analyse the sonographic findings of focal splenic lesions with an attempt to differentiate benign lesions from malignancies. The sonographic findings of 53 cases of...
