Kavli Affiliate: Vinothan N. Manoharan | First 5 Authors: Xander M. de Wit, Amelia W. Paine, Caroline Martin, Aaron M. Goldfain, Rees F. Garmann | Summary: Interferometric scattering microscopy (iSCAT) can image the dynamics of nanometer-scale systems. The typical approach to analyzing interferometric images involves intensive processing, which discards data and limits the precision of […]

Kavli Affiliate: L. Mahadevan | First 5 Authors: J. S. Yodh, F. Giardina, S. Gokhale, L. Mahadevan, | Summary: At sufficiently high concentrations, motile bacteria suspended in fluids exhibit a range of ordered and disordered collective motions. Here we explore the combined effects of confinement, periodicity and curvature induced by the active motion of E. […]

Kavli Affiliate: Zhigang Suo | First 5 Authors: Manyuan Tao, Shawn Lavoie, Zhigang Suo, Maria K. Cameron, | Summary: A polymer network fractures by breaking covalent bonds, but the experimentally measured strength of the polymer network is orders of magnitude lower than the strength of covalent bonds. We investigate the effect of statistical variation of […]

Kavli Affiliate: L. Mahadevan | First 5 Authors: N. Charles, R. Chelakkot, M. Gazzola, B. Young, L. Mahadevan | Summary: Of the vast variety of animal gaits, one of the most striking is the non-planar undulating motion of a sidewinder. But non-planar gaits are not limited to sidewinders. Here we report a new non-planar mode […]

Kavli Affiliate: David A. Weitz | Authors: Sijie Sun, Nan Xue, Stefano Aime, Hyoungsoo Kim, Jizhou Tang, Gareth H. McKinley, Howard A. Stone, David A. Weitz | Summary: Addition of particles to a viscoelastic suspension dramatically alters the properties of the mixture, particularly when it is sheared or otherwise processed. Shear-induced stretching of the polymers […]

Weitz | First 5 Authors: Sijie Sun, Nan Xue, Stefano Aime, Hyoungsoo Kim, Jizhou Tang | Summary: Addition of particles to a viscoelastic suspension dramatically alters the properties of the mixture, particularly when it is sheared or otherwise processed. Shear-induced stretching of the polymers results in elastic stress that causes a […]

Kavli Affiliate: Michael P. Brenner | First 5 Authors: Subhashini Venugopalan, Jimmy Tobin, Samuel J. Yang, Katie Seaver, Richard J. N. Cave | Summary: We developed dysarthric speech intelligibility classifiers on 551,176 disordered speech samples contributed by a diverse set of 468 speakers, with a range of self-reported speaking disorders and rated for their overall […]

Kavli Affiliate: Ariel Amir | First 5 Authors: Tabea Heckenthaler, Tobias Holder, Ariel Amir, Ofer Feinerman, Ehud Fonio | Summary: Some ant species are known as efficient transporters that can cooperatively carry food items which would be too large for a single ant. Previous studies of cooperative transport focused on the role of individual ants […]

Kavli Affiliate: Ariel Amir | First 5 Authors: Tabea Heckenthaler, Tobias Holder, Ariel Amir, Ofer Feinerman, Ehud Fonio | Summary: Paratrechina longicornis ants are known for their ability to cooperatively transport large food items. Previous studies have focused on the behavioral rules of individual ants and explained the efficient coordination using the coupled-carrier model. In […]
