congenital nasolacrimal duct obstruction (cnldo) is a common disease in children. the classic treatment of cnldo is probing that was done around one year old. however, controversy exists regarding the outcome of probing in children older than one year. this study aimed to find the cure rate of initial probing for cnldo and identify factors producing the failure rate in old age. in this retrospe...

S15/O01 eAntarctica: From data management to information portals Belbin L. Australian Antarctic Division, Kingston, Australia Scientific research is driven by data. Data is valued by the scientific community for its ability to prove or disprove hypotheses. Data can be valued independently by the cost of collection and processing; Antarctic data is extremely expensive. It is therefore anomalous,...

Abstract[1] Natural resources as a source of wealth can increase prosperity or impede economic growth.  Empirical studies with different specifications and data are also mixed on whether natural resources are curse or blessing. In fact, the variety of model specifications, measurements, and samples in the empirical literature makes it difficult to generalize the results. In this study, a growth...

We formulate multiple correspondence analysis (MCA) as a nonlinear multivariate analysis method that integrates ideas from multidimensional scaling. MCA is introduced as a graphical technique that minimizes distances between connecting points in a graph plot. We use this geometrical approach to show how questions posed of categorical marketing research data may be answered with MCA in terms of ...

We demonstrate generation and frequency doubling of unit charge vortices in a linear astigmatic resonator. Topological instability of the double charge harmonic vortices leads to well separated vortex cores that are shown to rotate, and become anisotropic, as the resonator is tuned across resonance. Creation, doubling, and splitting, of vortices in intracavity second harmonic generation2 Optica...
