While problems with cell line misidentification have been known for decades, an unknown number of published papers remains in circulation reporting on the wrong cells without warning or correction. Here we attempt to make a conservative estimate of this 'contaminated' literature. We found 32,755 articles reporting on research with misidentified cells, in turn cited by an estimated half a millio...

Early warning systems (EWS) tend to focus on the identification of slow onset disasters such famine and epidemic disease. Since hazardous environmental conditions often precede disastrous outcomes by many months, effective monitoring via satellite and in situ observations can successfully guide mitigation activities. Accurate short term forecasts of NDVI could increase lead times, making early ...

Intersection collisions account for a significant portion of accidents and fatalities on roadways. We are developing a vehicle-to-vehicle cooperative collision warning system as part of our effort to enhance driver’s awareness of roadway situation and to reduce the accident rate. Central to the system is a threat assessment algorithm that is based on location and velocity information of the sub...

This study examines the situation that produced a high-tech industry (software development) despite the generally deprived conditions in the country. The authors examine the legacy of colonialism, the ensuing democracy with a socialist bent, and how the global software industry emerged. Clearly the education system and the prevailing infrastructure in a small southern region of the country were...

An outline of a planned system for the global space-weather monitoring network of NICT (National Institute of Information and Communications Technology) is given. This system can manage data collection much easier than our current system, by installations of autonomous recovery, periodical state monitoring, and dynamic warning procedures. According to a provisional experiment using a network si...

Over the past few months, we have witnessed a number of tragedies that could potentially have been prevented. These include the alligator attack on a 2-year old boy at Disney and the shooting of Harambe the Gorilla at the Cincinnati Zoo when a child made his way into the exhibit area. Perhaps, better and more salient warning signs would have made a difference. Recently, there has been a game sw...

Abrupt transitions are ubiquitous in the dynamics of complex systems. Finding precursors, i.e. early indicators of their arrival, is fundamental in many areas of science ranging from electrical engineering to climate. However, obtaining warnings of an approaching transition well in advance remains an elusive task. Here we show that a functional network, constructed from spatial correlations of ...

Warning system effectiveness is critically important in selecting an appropriate emergency warning system to alert to public to potential danger. This paper examines warning system effectiveness in terms of the timing of warning receipt and response. Warning receipt involves the analysis of when warning system information is received, which includes alerting the public and delivering a warning ...
