Sense of Place: An Elusive Concept That is Finding a Home in Ecosystem Management

"Sense of place" offers esource managers a way to identify and respond to the emotional and spiritual bonds people form with certain spaces. We examine reasons forthe increasing interest in he concept and offer four broad recommendations for applying sense of place to ecosystem management. By i itiating a discussion about sense ofplace, managers can build a working relationship withthe public t...

Motion Models that Only Work Sometimes

It is too often that tracking algorithms lose track of interest points in image sequences. This persistent problem is difficult because the pixels around an interest point change in appearance or move in unpredictable ways. In this paper we explore how classifying videos into categories of camera motion improves the tracking of interest points, by selecting the right specialist motion model for...

RAS Synthetic Lethal Screens Revisited: Still Seeking the Elusive Prize?

The RAS genes are critical oncogenic drivers activated by point mutation in some 20% of human malignancies. However, no pharmacologic approaches to targeting RAS proteins directly have yet succeeded, leading to suggestions that these proteins may be "undruggable." This has led to two alternative indirect approaches to targeting RAS function in cancer. One has been to target RAS signaling pathwa...

That Elusive Diversity in Classifier Ensembles

Is “useful diversity” a myth? Many experiments and the little available theory on diversity in classifier ensembles are either inconclusive, too heavily assumption-bound or openly non-supportive of the intuition that diverse classifiers fare better than non-divers ones. Although a rough general tendency was confirmed in our previous studies, no prominent link appeared between diversity of the e...
