Kavli Affiliate: David Weitz | First 5 Authors: Andrea Montessori, Marco Lauricella, Michele La Rocca, Sauro Succi, Elad Stolovicki | Summary: We present a regularized version of the color gradient lattice Boltzmann (LB) scheme for the simulation of droplet formation in microfluidic devices of experimental relevance. The regularized version is shown to provide computationally efficient […]

Kavli Affiliate: Anna V. Shneidman | First 5 Authors: Ian B. Burgess, Navid Abedzadeh, Theresa M. Kay, Anna V. Shneidman, Derek J. Cranshaw | Summary: Although complex, hierarchical nanoscale geometries with tailored degrees of disorder are commonly found in biological systems, few simple self-assembly routes to fabricating synthetic analogues have been identified. We present two […]

Kavli Affiliate: Radhika Nagpal | First 5 Authors: Alejandro Cornejo, Radhika Nagpal, , , | Summary: This paper studies the problem of having mobile robots in a multi-robot system maintain an estimate of the relative position and relative orientation of near-by robots in the environment. This problem is studied in the context of large swarms […]

Kavli Affiliate: David Weitz | First 5 Authors: David Issadore, Katherine J. Humphry, Keith A. Brown, Lori Sandberg, David Weitz | Summary: We present a technique to locally and rapidly heat water drops in microfluidic devices with microwave dielectric heating. Water absorbs microwave power more efficiently than polymers, glass, and oils due to its permanent […]

Kavli Affiliate: George M. Whitesides | First 5 Authors: Eric Lauga, Willow R. DiLuzio, George M. Whitesides, Howard A. Stone, | Summary: Near a solid boundary, E. coli swims in clockwise circular motion. We provide a hydrodynamic model for this behavior. We show that circular trajectories are natural consequences of force-free and torque-free swimming, and […]

Kavli Affiliate: Robert Wood | First 5 Authors: Gad Getz, Hilah Gal, Itai Kela, Eytan Domany, Dan A. Notterman | Summary: We present and review Coupled Two Way Clustering, a method designed to mine gene expression data. The method identifies submatrices of the total expression matrix, whose clustering analysis reveals partitions of samples (and genes) […]
