Inorganic arsenic-the more acutely toxic form of this metalloid element-contaminates drinking water supplies around the world. In the United States, the most serious arsenic contamination occurs in the West, Midwest, Southwest, and Northeast; as many as 20 million people-many getting their water from unregulated private wells-may be exposed to excess arsenic in their drinking water. In Banglade...

Microstructure noise contaminates high-frequency estimates of asset price volatility. Recent work has determined a preferred sampling frequency under the assumption that the properties of noise are constant. Given the sampling frequency, the highfrequency observations are given equal weight. While convenient, constant weights are not necessarily efficient. We use the Kalman filter to derive mor...

Chemical contaminants in food have caused serious health issues in both humans and animals. Microarray technology is an advanced technique suitable for the analysis of chemical contaminates. In particular, immuno-microarray approach is one of the most promising methods for chemical contaminants analysis. The use of microarrays for the analysis of chemical contaminants is the subject of this rev...

In this paper, we explore the linkage between bank opacity and charter value. We find that contaminates value therefore reduces ability of to restrain risk-taking in banking. As assets become more complex opaque with increased use derivative like mortgage backed securities, asset collateralised debt obligations, etc., it becomes difficult gauge true banks risk activities.

This study presents a technique for separation of Heart Sound Signal (HSS) from Lung Sound Signal (LSS) using Adaptive Line Enhancer (ALE) with Least Mean Square (LMS) algorithm with real time recorded sound signal. While recording lung sounds, an incessant noise source takes place owing to heart sounds. This noise source severely contaminates the breath sound signal and interferes in the analy...
