Examples of such a data type include hyperlinked Web pages, academic publications with citations, and user profiles in social networks. Such data have very high-dimensional representations, in terms of text as well as network connectivity. In this paper, we study the problem of embedding, or finding a low-dimensional representation of a document network that "preserves" the data as much as possible. These embedded representations are useful for various applications driven by dimensionality reduction, such as visualization or feature selection. While previous works in embedding have mostly focused on either the textual aspect or the network aspect, we advocate a holistic approach by finding a unified low-rank representation for both aspects. Moreover, to lend semantic interpretability to the low-rank representation, we further propose to integrate topic modeling and embedding within a joint model. The gist is to join the various representations of a document (words, links, topics, and coordinates) within a generative model, and to estimate the hidden representations through MAP estimation. We validate our model on real-life document networks, showing that it outperforms comparable baselines comprehensively on objective evaluation metrics.

The properties of the coal used in different power plants cross the India vary widely, but most of the times the sulfur contents are low in the coals. As a result the resistivity of the fly ash is in general, very high and it leads to develop back corona at the collecting electrodes even at comparatively low current densities flowing through the different fields of ESP. All this results in detorieting the Collection efficiency of ESP and large size of ESP is required to meet the emission standard for similar level of power generation elsewhere. Knowledge of electrical resistivity is essential for sizing of ESP and to determine a strategy to improve its performance. A special facility has been developed at IIT Delhi to investigate the variation of resistivity at different temperature and moisture levels under simulated conditions...

This literature builds on diverse intellectual traditions.

He proposed that by cutting the blood supply off, cancer cells can be deprived of nutrients and hence treated. His efforts were paid off when Bevacizumab (Avastin ®), a monoclonal antibody against the vascular endothelial growth factor (VEGF) was first approved for anti-angiogenic therapy in 2004 for the treatment of breast cancer. Since then, an array of anti-angiogenic inhibitors were developed, used in clinical trials and many got approved for use for the treatment of multiple cancers, alone or in combination with other cytotoxic/chemotherapy drugs. Despite this important breakthrough, anti-angiogenic therapy for cancer met with a number of hurdles on its way to be one of the options for cancer therapy. Herein, we summarize the latest update on the current knowledge on the mechanisms of tumor angiogenesis, pro-and anti-angiogenic factors, potential targets and their mechanisms of action, experimental evidences and the most recent data on the clinical trials on anti-angiogenic agents for cancer therapy.
