Geometric frustration of hard-disk packings on cones

Kavli Affiliate: Vinothan N. Manoharan | First 5 Authors: Jessica H. Sun, Abigail Plummer, Grace H. Zhang, David R. Nelson, Vinothan N. Manoharan | Summary: Conical surfaces pose an interesting challenge to crystal growth: a crystal growing on a cone can wrap around and meet itself at different radii. We use a disk-packing algorithm to […]

Exact coherent structures in two-dimensional turbulence identified with convolutional autoencoders

Kavli Affiliate: Michael P. Brenner | First 5 Authors: Jacob Page, Joe Holey, Michael P. Brenner, Rich R. Kerswell, | Summary: Convolutional autoencoders are used to deconstruct the changing dynamics of two-dimensional Kolmogorov flow as $Re$ is increased from weakly chaotic flow at $Re=40$ to a chaotic state dominated by a domain-filling vortex pair at […]

Approximate Lie symmetries and singular perturbation theory

Kavli Affiliate: L. Mahadevan | First 5 Authors: Alexander J. Dear, L. Mahadevan, , , | Summary: Perturbation theory plays a central role in the approximate solution of nonlinear differential equations. The resultant series expansions are usually divergent and require treatment by singular perturbation methods to generate uniformly valid solutions. However, applying these methods is […]

Approximate Lie symmetries and singular perturbation theory

Kavli Affiliate: L. Mahadevan | First 5 Authors: Alexander J. Dear, L. Mahadevan, , , | Summary: Singular perturbation theory plays a central role in the approximate solution of nonlinear differential equations. However, applying these methods is a subtle art owing to the lack of globally applicable algorithms. Inspired by the fact that all exact […]

Optimal strategies for kiiking: active pumping to invert a swing

Kavli Affiliate: L. Mahadevan | First 5 Authors: Petur Bryde, Ian C. Davenport, L. Mahadevan, , | Summary: Kiiking is an extreme sport in which athletes alternate between standing and squatting to pump a standing swing till it is inverted and completes a rotation. A minimal model of the sport may be cast in terms […]

Unravelling the Mechanics of Knitted Fabrics Through Hierarchical Geometric Representation

Kavli Affiliate: Katia Bertoldi | First 5 Authors: Xiaoxiao Ding, Vanessa Sanchez, Katia Bertoldi, Chris H. Rycroft, | Summary: Knitting interloops one-dimensional yarns into three-dimensional fabrics that exhibit behaviours beyond their constitutive materials. How extensibility and anisotropy emerge from the hierarchical organization of yarns into knitted fabrics has long been unresolved. We sought to unravel […]

Roles of intrinsically disordered regions in transcription factor search

Kavli Affiliate: Ariel Amir | First 5 Authors: Wencheng Ji, Ori Hachmo, Naama Barkai, Ariel Amir, | Summary: Transcription Factors (TFs) are proteins that regulate gene expression. The regulation mechanism is via the binding of a TF to a specific part of the gene associated with it, the TF’s target. For the regulation to be […]
