Developers and security analysts have been using static analysis for a long time to analyze programs for defects and vulnerabilities. Generally a static analysis tool is run on the source code for a given program, flagging areas of code that need to be further inspected by a human analyst. These tools tend to work fairly well – every year they find many important bugs. These tools are more impr...

8 Nonlinear wave-wave interactions generate double-frequency (DF) microseisms, 9 which include both surface waves (mainly Rayleigh-type) and compressional (P) waves. 10 Although it is unclear whether DF surface waves generated in deep oceans are observed 11 on land, we show that DF P waves generated under Super Typhoon Ioke far offshore are 12 detected by beamforming of land-based seismic array...

Watersheds are recognized as the most effective management unit for the protection of water resources. For surface water supplies that use water from upstream watersheds, evaluating threats to water quality and implementing a watershed management plan are crucial for the maintenance of drinking water safe for humans. The aim of this article is to establish a risk assessment model that provides ...

Computation plays an increasing role in biology. We argue that a new approach, which we call “open source drug discovery,” would significantly reduce the cost of discovering, developing, and manufacturing cures for tropical diseases. First, it would give hundreds of scientists a practical way to donate urgently needed manpower. Second, open source discoveries would not be patented. This would p...

We consider an online learning problem (classification or prediction) involving disparate sources of sequentially arriving data, whereby a user over time learns the best set of data sources to use in constructing the classifier by exploiting their similarity. We first show that, when (1) the similarity information among data sources is known, and (2) data from different sources can be acquired ...

background : hedgehogs are small, nocturnal mammals which become popular in the world and have important role in transmission of zoonotic agents. thus, the present study aimed to survey ectoparasite infestation from april 2010 to december 2011 in urban and suburban parts of urmia and tabriz cities, northwest of iran. methods : a total number of 84 hedgehogs (40 females and 44 males) were examin...

In this study we characterize the long-range transport of allergenic pollen to the North East of Spain. To this end, cluster analysis of back-trajectories and a source-receptor model was applied to a dataset of 10 years of airborne monitoring data corresponding to the period 2000-2009. The aim of the study is to examine and interpret the main transport routes and source areas affecting levels i...
