MuA-Ori: Multimodal Actuated Origami

Kavli Affiliate: Katia Bertoldi | First 5 Authors: Antonio Elia Forte, David Melancon, Leon M. Kamp, Benjamin Gorissen, Katia Bertoldi | Summary: Recently, inflatable elements integrated in robotics systems have enabled complex motions as a result of simple inputs. However, these fluidic actuators typically exhibit unimodal deformation upon inflation. Here, we present a new design […]

Intersonic Detachment Surface Waves in Elastomer Frictional Sliding

Kavli Affiliate: David A. Weitz | First 5 Authors: Huifeng Du, Emmanuel Virot, Liying Wang, Sam Kharchenko, Md Arifur Rahman | Summary: Elastomeric materials when sliding on clean and rough surfaces generate wrinkles at the interface due to tangential stress gradients. These interfacial folds travel along the bottom of elastomer as surface detachment waves to […]

Computing the viscous effect in early-time drop impact dynamics

Kavli Affiliate: Shmuel M. Rubinstein | First 5 Authors: Shruti Mishra, Shmuel M. Rubinstein, Chris H. Rycroft, , | Summary: The impact of a liquid drop on a solid surface involves many intertwined physical effects, and is influenced by drop velocity, surface tension, ambient pressure and liquid viscosity, among others. Experiments by Kolinski et al. […]

Active microphase separation in mixtures of microtubules and tip-accumulating molecular motors

Kavli Affiliate: Daniel J. Needleman | First 5 Authors: Bezia Lemma, Noah P. Mitchell, Radhika Subramanian, Daniel J. Needleman, Zvonimir Dogic | Summary: Mixtures of microtubules and molecular motors form active materials with diverse dynamical behaviors that vary based on their constituents’ molecular properties. We map the non-equilibrium phase diagram of microtubules and tip-accumulating kinesin-4 […]

Using a Cross-Task Grid of Linear Probes to Interpret CNN Model Predictions On Retinal Images

Kavli Affiliate: Michael P. Brenner | First 5 Authors: Katy Blumer, Subhashini Venugopalan, Michael P. Brenner, Jon Kleinberg, | Summary: We analyze a dataset of retinal images using linear probes: linear regression models trained on some "target" task, using embeddings from a deep convolutional (CNN) model trained on some "source" task as input. We use […]

Developmental Stage Classification of Embryos Using Two-Stream Neural Network with Linear-Chain Conditional Random Field

Kavli Affiliate: Daniel Needleman | First 5 Authors: Stanislav Lukyanenko, Won-Dong Jang, Donglai Wei, Robbert Struyven, Yoon Kim | Summary: The developmental process of embryos follows a monotonic order. An embryo can progressively cleave from one cell to multiple cells and finally transform to morula and blastocyst. For time-lapse videos of embryos, most existing developmental […]

Comparing Supervised Models And Learned Speech Representations For Classifying Intelligibility Of Disordered Speech On Selected Phrases

Kavli Affiliate: Michael P. Brenner | First 5 Authors: Subhashini Venugopalan, Joel Shor, Manoj Plakal, Jimmy Tobin, Katrin Tomanek | Summary: Automatic classification of disordered speech can provide an objective tool for identifying the presence and severity of speech impairment. Classification approaches can also help identify hard-to-recognize speech samples to teach ASR systems about the […]

Temporal Evolution of Flow in Pore-Networks: From Homogenization to Instability

Kavli Affiliate: Ariel Amir | First 5 Authors: Ahmad Zareei, Deng Pan, Ariel Amir, , | Summary: We study the dynamics of flow-networks in porous media using a pore-network model. First, we consider a class of erosion dynamics assuming a constitutive law depending on flow rate, local velocities, or shear stress at the walls. We […]

Improving holographic particle characterization by modeling spherical aberration

Kavli Affiliate: Vinothan Manoharan | First 5 Authors: Caroline Martin, Brian Leahy, Vinothan Manoharan, , | Summary: Holographic microscopy combined with forward modeling and inference allows colloidal particles to be characterized and tracked in three dimensions with high precision. However, current models ignore the effects of optical aberrations on hologram formation. We investigate the effects […]
