I am a pediatric emergency physician in Calgary, Alta, and have been active in international health for more than 25 years. The last time I had been in Africa was in 1985 when I ran a district hospital in Lesotho in southern Africa. My husband and I had always wanted to return to the continent but career, children, and time got in the way. When those factors finally aligned, we were able to onc...

We study the current best model (Krishnamurthy et al., 2017) (KDG) for question answering on tabular data evaluated over the WIKITABLEQUESTIONS dataset. Previous ablation studies performed against this model attributed the model’s performance to certain aspects of its architecture. In this paper, we find that the model’s performance also crucially depends on a certain pruning of the data used t...

The end of the last solar cycle was at least 3 years late, and to date, the new solar cycle has seen mainly weaker activity since the onset of the rising phase toward the new solar maximum. The newspapers now even report when auroras are seen in Norway. This paper is an update of our review paper written during the deepest part of the last solar minimum [1]. We update the records of solar activ...

The March 5th, 1979 gamma-ray transient has long been thought to be fundamentally di erent from the classic gamma-ray bursts (GRBs). It had recurrences, pulsations, and a soft spectral component unlike classic GRBs. With the exception of the soft component reported from the Konus experiment, the unusual characteristics of March 5th were detectable primarily because it was extremely bright. Comp...

Available online 12 September 2009 We develop a dynamic framework to identify aggregate market fears ahead of a major market crash through the skewness premium of European options. Our methodology is based on measuring the distribution of a skewness premium through a q-Gaussian density and a maximum entropy principle. Our findings indicate that the October 19th, 1987 crash was predictable from ...
