Improved methods are needed to evaluate barriers and traps for control and assessment of invasive sea lamprey (Petromyzon marinus) in the Great Lakes. A Bayesian state-space model provided reach-specific probabilities of movement, including trap capture and dam passage, for 148 acoustic tagged invasive sea lamprey in the lower Cheboygan River, Michigan, a tributary to Lake Huron. Reach-specific...

Increasing concern in the early 1990s over the negative impact of the end of the Cold War strengthened fears that the break-up of the Soviet Union would unleash a barrage of lethal ethnic wars and state failures. The resulting instability, it was argued, would displace millions of people and create a wake of social upheaval unparalleled in this century. The idea of an impending global crisis be...

We have traditionally viewed spam from the receiver’s point of view: mail servers assaulted by a barrage of spam from which we must pick out a handful of legitimate messages. In this paper we describe a system for better filtering spam by exploiting the vantage point of the spammer. By instantiating and monitoring botnet hosts in a controlled environment, we are able to monitor new spam as it i...

In the next few years, surveyors using high productivity, real-time kinematic (RTK) positioning and indeed all other precision positioning users will be faced with a barrage of new global navigation satellite system (GNSS) signals from GPS, GLONASS, GALILEO and possibly COMPASS/Beidou2 as well as Satellite Based Augmentation Systems (SBAS) signals and Regional Navigation Satellite Systems (RNSS...

The current barrage of information about real and potential cancer risks has created undue fears and misplaced concerns about cancer hazards faced by Americans. Most members of the general public are far more worried about minuscule, hypothetical risks presented by environmental contaminants than about the far greater well-established hazards that they inflict on themselves, for example, throug...

After herpes zoster, immunocompetent persons frequently experience chronic pain and considerable suffering. Zoster-associated pain has a complex pathophysiology that begins with viral damage and increased sensitization of peripheral sensory neurons. The enhanced afferent barrage from these neurons sensitizes spinal neurons and leads to loss of synapses from descending inhibitory fibers, resulti...
