Antarctic surface temperature and elevation during the Last Glacial Maximum

The Antarctic Vostok ice core provided compelling evidence of the nature of climate, and of climate feedbacks, over the past 420,000 years. Marine records suggest that the amplitude of climate variability was smaller before that time, but such records are ...

Small-time global stabilization of the viscous Burgers equation with three scalar controls

Shengquan Xiang

We construct explicit time-varying feedback laws leading to the global (null) stabilization in small time of the viscous Burgers equation with three scalar controls. Our feedback laws use first the quadratic transport term to achieve the small-time global ...

Whole Body Model Predictive Control with a Memory of Motion:Experiments on a Torque-Controlled Talos

Sylvain Calinon, Teguh Santoso Lembono, Rohan Budhiraja

This paper presents the first successful experiment implementing whole-body model predictive control with state feedback on a torque-control humanoid robot. We demonstrate that our control scheme is able to do whole-body target tracking, control the balanc ...

The embodied flow of built-up land in China?s interregional trade and its implications for regional carbon balance

Qinli Lu

Built-up land intensively concentrates human activities, and its area or the changes in its intensity dramatically affect the regional carbon balance. This study proposed a new framework to assess how in China, the interregional trade?s use of built-up lan ...

Material surface detection on various body parts: a preliminary study for temperature substitution for upper arm amputees

Silvestro Micera, Solaiman Shokur

Experiments have shown that healthy subjects can detect materials solely relying on the material's thermal properties at their fingertip. We are interested in developing a non-invasive temperature display for sensory substitution for patients with arm ampu ...

Exploring the Contribution of Proprioceptive Reflexes to Balance Control in Perturbed Standing

Auke Ijspeert, Anne Daniëlle Koelewijn

Humans control balance using different feedback loops involving the vestibular system, the visual system, and proprioception. In this article, we focus on proprioception and explore the contribution of reflexes based on force and length feedback to standin ...

A fast–slow model of banded vegetation pattern formation in drylands

Sara Bonetti

From infiltration of water into the soil during rainstorms to seasonal plant growth and death, the ecohydrological processes that are thought to be relevant to the formation of banded vegetation patterns in drylands occur across multiple timescales. We pro ...

More green and less blue water in the Alps during warmer summers

Gabriele Manoli, Peter Molnar, Paolo Burlando

Climate change can reduce surface-water supply by enhancing evapotranspiration in forested mountains, especially during heatwaves. We investigate this ‘drought paradox’ for the European Alps using a 1,212-station database and hyper-resolution ecohydrologic ...

Flocking-enhanced social contagion

Ignacio Pagonabarraga Mora

Populations of mobile agents-animal groups, robot swarms, or crowds of people-self-organize into a large diversity of states as a result of information exchanges with their surroundings. While in many situations of interest the motion of the agents is driv ...

AlloHaptic: Robot-Mediated Haptic Collaboration for Learning Linear Functions*

Pierre Dillenbourg, Barbara Bruno, Wafa Monia Benkaouar Johal, Hala Khodr, Aditi Kothiyal, Soheil Kianzad

Collaborative learning appears in a joint intellectual efforts of individuals to understand an object of knowledge collectively. In their search for understanding the problems, meanings, and solutions, learners employ different multi-modal strategies. In t ...
