Another Important Lesson from Military Surgery?

Knowingwhen awound can safely be closed is an iconic problem for surgery. When an extremity wound is closed too soon, with resulting infection requiring further debridement, an amputation can result. Or a minor amputation can be converted into a major amputation. Patient welfare is on the line, and expenses are considerable in these situations. The novel work (Forsberg et al. 2015), published i...

Another Lesson from Plants: The Forward Osmosis-Based Actuator

Osmotic actuation is a ubiquitous plant-inspired actuation strategy that has a very low power consumption but is capable of generating effective movements in a wide variety of environmental conditions. In light of these features, we aimed to develop a novel, low-power-consumption actuator that is capable of generating suitable forces during a characteristic actuation time on the order of a few ...

Recognizing Action at a Distance

Our goal is to recognize human actions at a distance, at resolutions where a whole person may be, say, 30 pixels tall. We introduce a novel motion descriptor based on optical flow measurements in a spatio-temporal volume for each stabilized human figure, and an associated similarity measure to be used in a nearest-neighbor framework. Making use of noisy optical flow measurements is the key chal...
