Research on botnet mitigation has focused predominantly on methods to technically disrupt the commandand-control infrastructure. Much less is known about the effectiveness of large-scale efforts to clean up infected machines. We analyze longitudinal data from the sinkhole of Conficker, one the largest botnets ever seen, to assess the impact of what has been emerging as a best practice: national...

Better site characterization is critical for cheaper, faster, and more effective cleanup. This fact is especially true as cleanup decisions increasingly include site redevelopment and reuse considerations. However, established attitudes about what constitutes “data quality” create many barriers to exciting new tools capable of achieving better characterization, slowing their dissemination into ...

Protein and peptide sample preparation for LC/MS remains entrenched in workflows reliant upon serial manual manipulations resulting in protocols lacking in throughput, scalability, and transferability. These workflows are often dependent on highly skilled practitioners to achieve acceptable reproducibility, or, in many cases, large variability is simply accepted as intrinsic to the workflow. To...

We present an all-quad meshing algorithm for general domains. We start with a strongly balanced quadtree. In contrast to snapping the quadtree corners onto the geometric domain boundaries, we move them away from the geometry. Then we intersect the moved grid with the geometry. The resulting polygons are converted into quads with midpoint subdivision. Moving away avoids creating any flat angles,...

Background: Ongoing conflict in the Middle East poses a major threat to health and security. A project screening Arab and Israeli newborns for hearing loss provided an opportunity to evaluate ways for building cooperation. The aims of this study were to: a) examine what attracted Israeli, Jordanian and Palestinian participants to the project, b) describe challenges they faced, and c) draw lesso...

This paper examines the role of liability for past environmental contamination in the privatization processes of Central and Eastern Europe. The theoretical section establishes a link between a risk-averse investor’s amount of information regarding the extent of past environmental contamination (and its cleanup costs) and the investor’s willingness to pay for a particular enterprise, i.e., bid....

The accuracy, repeatability, and reproducibility characteristics of a liquid chromatographic method for the determination of ochratoxin A (OTA) in white wine, red wine, and beer were established in a collaborative study involving 18 laboratories in 10 countries. Blind duplicates of blank, spiked, and naturally contaminated materials at levels ranging from < or =0.01 to 3.00 ng/mL were analyzed....

The U.S. Department of Energy (DOE) continues to emphasize the need for accelerated cleanup of its sites, including the decontamination and decommissioning (D&D) of former production facilities. At the same time, safeguarding the site personnel, the environment, and potentially affected interests outside the waste management professional field is of paramount importance. The need to balance bot...
