Effective Locomotion at Multiple Stride Frequencies Using Proprioceptive Feedback on a Legged Microrobot

Posted by klaurent Harvard

Kavli Affiliate: Robert J. Wood | First 5 Authors: Neel Doshi, Kaushik Jayaram, Samantha Castellanos, Scott Kuindersma, Robert J Wood | Summary: Limitations in actuation, sensing, and computation have forced small legged robots to rely on carefully tuned, mechanically mediated leg trajectories for effective locomotion. Recent advances in manufacturing, however, have enabled the development of […]

The ultra-diffuse galaxy NGC 1052-DF2 with MUSE: I. Kinematics of the stellar body

Posted by klaurent Peking

Kavli Affiliate: Eric Peng | First 5 Authors: Eric Emsellem, Remco F. J. van der Burg, Jeremy Fensch, Tereza Jerabkova, Anita Zanella | Summary: The so-called ultra-diffuse galaxy NGC~1052-DF2 was announced to be a galaxy lacking dark matter based on a spectroscopic study of its constituent globular clusters. Here we present the first spectroscopic analysis […]

Surface curvature guides early construction activity in mound-building termites

Posted by klaurent Harvard

Kavli Affiliate: Radhika Nagpal | First 5 Authors: Daniel S. Calovi, Paul Bardunias, Nicole Carey, J. Scott Turner, Radhika Nagpal | Summary: Termite colonies construct towering, complex mounds, in a classic example of distributed agents coordinating their activity via interaction with a shared environment. The traditional explanation for how this coordination occurs focuses on the […]

Jetting to dripping transition: critical aspect ratio in step emulsifiers

Posted by klaurent Harvard

Kavli Affiliate: David Weitz | First 5 Authors: Andrea Montessori, Marco Lauricella, Elad Stolovicki, David Weitz, Sauro Succi | Summary: Fully three-dimensional, time-dependent, direct simulations of the non-ideal Navier-Stokes equations for a two-component fluid, shed light into the mechanism which inhibits droplet breakup in step emulsifiers below a critical threshold of the the width-to-height ($w/h$) […]

Uncovering the dynamic precursors to motor-driven contraction of active gels

Posted by klaurent Delft

Kavli Affiliate: Gijsje Koenderink | First 5 Authors: Jose Alvarado, Luca Cipelletti, Gijsje Koenderink, , | Summary: Cells and tissues have the remarkable ability to actively generate the forces required to change their shape. This active mechanical behavior is largely mediated by the actin cytoskeleton, a crosslinked network of actin filaments that is contracted by […]

Ground motion prediction at gravitational wave observatories using archival seismic data

Posted by klaurent MIT

Kavli Affiliate: Richard Mittleman | First 5 Authors: Nikhil Mukund, Michael Coughlin, Jan Harms, Sebastien Biscans, Jim Warner | Summary: Gravitational wave observatories have always been affected by tele-seismic earthquakes leading to a decrease in duty cycle and coincident observation time. In this analysis, we leverage the power of machine learning algorithms and archival seismic […]

Candidate Massive Galaxies at $z sim 4$ in the Dark Energy Survey

Posted by klaurent Stanford

Kavli Affiliate: Rafe Schindler | First 5 Authors: Pierandrea Guarnieri, Claudia Maraston, Daniel Thomas, Janine Pforr, Violeta Gonzalez-Perez | Summary: Using stellar population models, we predicted that the Dark Energy Survey (DES) – due to its special combination of area (5000 deg. sq.) and depth ($i = 24.3$) – would be in the position to […]
