Localization in musical steelpans
Petur Bryde, L. Mahadevan
The steelpan is a pitched percussion instrument that takes the form of a concave bowl with several localized dimpled regions of varying curvature. Each of these localized zones, ca…
Explosive rigidity percolation in kirigami
Gary P. T. Choi, Lucy Liu, L. Mahadevan
Controlling the connectivity and rigidity of kirigami, i.e. the process of cutting paper to deploy it into an articulated system, is critical in the manifestations of kirigami in a…
Contractility-induced phase separation in active solids
Sifan Yin, L Mahadevan
A combination of cellular contractility and active phase separation in cell-matrix composites is thought to be an enabler of spatiotemporal patterning in multicellular tissues acro…
Optimal intercellular competition in senescence and cancer
Thomas C. T. Michaels, L. Mahadevan
Effective multicellularity requires both cooperation and competition between constituent cells. Cooperation involves sacrificing individual fitness in favor of that of the communit…
An additive framework for kirigami design
Levi H. Dudte, Gary P. T. Choi, Kaitlyn P. Becker +1
We present an additive approach for the inverse design of kirigami-based mechanical metamaterials by focusing on the empty (negative) spaces instead of the solid tiles. By consider…
How to grow a flat leaf
Salem al-Mosleh, L. Mahadevan
Growing a flat lamina such as a leaf is almost impossible without some feedback to stabilize long wavelength modes that are easy to trigger since they are energetically cheap. Here…
: Collective behavior mediated by active flow-based recruitment
S Ganga Prasath, L Mahadevan
The physics of signal propagation in a collection of organisms that communicate with each other both enables and limits how active excitations at the individual level reach, recrui…
Active entanglement enables stochastic, topological grasping
Kaitlyn Becker, Clark Teeple, Nicholas Charles +5
Grasping, in both biological and engineered mechanisms, can be highly sensitive to the gripper and object morphology, as well as perception, and motion planning. Here we circumvent…
Modular representation and control of floppy networks
Siheng Chen, Fabio Giardina, Gary P. T. Choi +1
Geometric graph models of systems as diverse as proteins, robots, and mechanical structures from DNA assemblies to architected materials point towards a unified way to represent an…
