We show that a tree substitution grammar (TSG) induced with a collapsed Gibbs sampler results in lower perplexity on test data than both a standard context-free grammar and other heuristically trained TSGs, suggesting that it is better suited to language modeling. Training a more complicated bilexical parsing model across TSG derivations shows further (though nuanced) improvement. We conduct an...

We report, for the first time, a fabrication process for building highly smooth, symmetric 3-D dynamic wineglass structures using low internal loss materials, namely fused quartz and ultra low expansion titania silicate glass (ULE TSG). The approach consists of a high temperature (at 1650 °C) micro-glassblowing process and a novel inverted-wineglass architecture that provides self-aligned stem ...

Dorsal cell fate in Drosophila embryos is specified by an activity gradient of Decapentaplegic (Dpp), a homologue of bone morphogenetic proteins (Bmps) 2/4. Previous genetic and biochemical studies have revealed that the Sog, Tsg and Tld proteins modify Dpp activity at the post-transcriptional level. The predominant view is that Sog and Tsg form a strong ternary complex with Dpp that prevents i...

he cattle tick, Rhipicephalus microplus, is the main ectoparasite of livestock in tropical countries, in Thailand particularly. This tick causes a range of problems, including anemia, widespread production losses, as well as lethal tick-borne diseases in animals. Control of tick infestations is based on the use of chemical acaricides, which have numerous undesirable side-effects, for example, e...

Sport is the most universal of cultural pursuits – it is accessible and of interest to all. Traditional Sports and Games (TSG) are as diverse as our cultures. TSG organisations work tirelessly to promote participation in their sports, but also act as custodians of custom, language and history. However, trends in globalisation have led to a convergence of the majority of spectator interest to ju...

Lossless compression is studied for a countably infinite alphabet source with an unknown, off-centered, two-sided geometric (TSG) distribution, which is a commonly used statistical model for image prediction residuals. In this paper, we demonstrate that arithmetic coding based on a simple strategy of model adaptation, essentially attains the theoretical lower bound to the universal coding redun...
