Modeling Landscape-Level Impacts of HWA in Shenandoah National Park

Eastern hemlock is in decline in many parts of its range in the eastern United States due primarily to infestation by the hemlock woolly adelgid (HWA). In Shenandoah National Park, HWA rapidly killed many hemlock stands after first appearing in 1989. While the severity of hemlock decline in Shenandoah National Park may preclude saving the hemlock forest component, an examination of the progress...

The PEAR proposition.

For more than a quarter century, the Princeton Engineering Anomalies Research (PEAR) laboratory has engaged in a broad range of experiments on consciousness-related physical anomalies and has proposed a corresponding selection of theoretical models that have combined to illuminate the fundamental nature of the provocative phenomena that emerge. Productive pursuit of this topic has inescapably i...
