1. Homozygous α-thalassaemia-1 can be predicted reliably using ultrasound measurement of the foetal cardiothoracic ratio at 12 to 13 weeks’ gestation, but not at 10 to 11 weeks’ gestation. 2. When an optimal foetal cardiothoracic ratio cannot be obtained with an abdominal ultrasound examination at 12 to 13 weeks’ gestation, a vaginal ultrasound examination is useful. 3. The use of ultrasonograp...

Poor sitting posture is a common problem among the elderly, especially in nursing homes residents.1 Contributory factors include kyphotic changes in the spine resulting in limited flexibility; decline in muscle strength and trunk control and general loss of condition, all of which impair the ability to maintain normal posture in the sitting position.2 Moreover, prolonged sitting with poor postu...

Earlier investment practices show that there lies a discrepancy between the actual fund strategy and stated fund strategy. Using a minimum spanning tree (MST) and planar maximally-filtered graph (PMFG), we build a network of open-ended funds in China’s market and investigate the evolution characteristics of the networks over multiple time periods and timescales. The evolution characteristics, e...

We argue that mutual fund investors are more sensitive to salient in-your-face fees, like loads and commissions, than operating expenses. Our empirical analysis of mutual fund flows over the last 30 years yields strong support for our contention. We find consistently negative relations between fund flows and load fees. We also document a negative relation between fund flows and commissions char...

We investigate the effectiveness of window-dressing as a potential strategy to be used by mutual fund managers to promote fund flows. Using a rank gap measure as a proxy for the likelihood that window-dressing has occurred, we find that fund investors as whole punish those managers who are suspected to have engaged in window-dressing. That is, we find a negative relation between the window-dres...

The phase synchronization problem requires each node to infinitely transfer from one phase to the next one under the restriction that at most two consecutive phases can appear among all nodes. In this paper, we propose a self-stabilizing algorithm under the parallel execution model to solve this problem for semi-uniform systems of general graph topologies. The proposed algorithm is memory-effic...
