Thermal cycling tests are carried out under a temperature gradient using specimens of thermal barrier coating (TBC). Vertical cracks in the topcoat grow direction thickness, and transverse topcoat, which can lead to delamination, vicinity interface with bondcoat. At 1223 K at substrate surface, heat flux 1.39 MW/m2, remarkable growth is observed, whereas slower lower temperatures conditions. Th...
This paper aims to show how we can make progress in elucidating how people understand speech by changing our focus of inquiry from abstraction of formal units of linguistic analysis to a detailed analysis of global aspects of the communicative situation, of which speech is just one part. It uses evidence of (a) the communicative importance of fine phonetic detail and (b) exemplar memory for spe...
It has long been a concern that performance measures of species distribution models react to attributes of the modeled entity arising from the input data structure rather than to model performance. Thus, the study of Allouche et al. (Journal of Applied Ecology, 43, 1223, 2006) identifying the true skill statistics (TSS) as being independent of prevalence had a great impact. However, empirical e...
BACKGROUND The aetiological role of human papillomavirus (HPV) in oesophageal squamous cell carcinoma (OSCC) has been widely researched for more than three decades, with conflicting findings. In the absence of a large, adequately powered single case-control study, a meta-analysis of all available case-control studies is the most rigorous way of identifying any potential association between HPV ...
