Into Darkness
Visual navigation of mobile robots has become a core capability that enables many interesting applications from planetary exploration to self-driving cars. While systems built on passive cameras have been shown to be robust in well-lit scenes, they cannot handle the range of conditions associated with a full diurnal cycle. Lidar, which is fairly invariant to ambient lighting conditions, offers ...
متن کاملJourney Into “The Heart of Darkness” REDUX
With the publication of The Psychology of Genocide, Massacres, and Extreme Violence: Why “Normal” People Come to Commit Atrocities, Donald Dutton, a distinguished professor of psychology at the University of British Columbia, joins Joseph Conrad, Francis Ford Coppola, and a host of professional peers as a commentator on the nature and origins of human evil. Dutton's volume, however, is neither ...
متن کاملFrom Darkness into Light: Factors Controlling Photomorphogenesis
A seedling that emerges in darkness follows a developmental program known as skotomorphogenesis (dark development), which is characterized by etiolation, that is, a long, spindly hypocotyl and pale cotyledons and inhibition of chlorophyll and anthocyanin biosynthesis and true leaf development. Upon exposure to light, the seedling switches rapidly to photomorphogenesis (light development); the h...

متن کاملProteomic Insight into the Response of Arabidopsis Chloroplasts to Darkness
Chloroplast function in photosynthesis is essential for plant growth and development. It is well-known that chloroplasts respond to various light conditions. However, it remains poorly understood about how chloroplasts respond to darkness. In this study, we found 81 darkness-responsive proteins in Arabidopsis chloroplasts under 8 h darkness treatment. Most of the proteins are nucleus-encoded, i...
