In this study, we introduce a new type of surface curves called $D$-type curve. This curve is defined by the property that the unit Darboux vector $vec{W}_{0} $ of a surface curve $vec{r}(s)$ and unit surface normal $vec{n} $ along the curve $vec{r}(s)$ satisfy the condition $leftlangle vec{n} ,vec{W}_{0} rightrangle =text{constant}$. We point out that a $D$-type curve is a geodesic curve or an...

Proximal pulmonary artery (PA) stiffening is a strong predictor of mortality in pulmonary hypertension. Collagen accumulation is mainly responsible for PA stiffening in hypoxia-induced pulmonary hypertension (HPH) in mouse models. We hypothesized that collagen cross-linking and the type I isoform are the main determinants of large PA mechanical changes during HPH, which we tested by exposing mi...

Text emotion detection refers to identifying the type of emotion getting used by the text. The process involves two process training and testing. The training section involves training the classifier with the text and the testing section involves the identification of the type of text used. After this accuracy of the classifier is checked by measuring how many correct labels of the text does th...

We present results from evaluations of an automatic text summarization technique that uses a combination of Random Indexing and PageRank. In our experiments we use two types of texts: news paper texts and government texts. Our results show that text type as well as other aspects of texts of the same type influence the performance. Combining PageRank and Random Indexing provides the best results...

Previous studies have focused on written English and only occasionally have they considered the question of whether these changes are affected by text type. The default assumption appears to be that change over time in written English is representative of changes more generally and that, if text type makes a difference, the effect of this variation is minor. However, synchronic studies in both ...
