Clogging of cohesive particles in a two-dimensional hopper
Johnathan Hoggarth, Pablo E. Illing, Eric R. Weeks +1
We study clogging of cohesive particles in a 2D hopper with experiments and simulations. The system consists of buoyant, monodisperse oil droplets in an aqueous solution, where the…
Forward Only Learning for Orthogonal Neural Networks of any Depth
Paul Caillon, Alex Colagrande, Erwan Fagnou +2
Backpropagation is still the de facto algorithm used today to train neural networks. With the exponential growth of recent architectures, the computational cost of this algorithm a…
Allometric scaling of brain activity explained by avalanche criticality
Tiago S. A. N. Simões, José S. Andrade, Hans J. Herrmann +2
Allometric scaling laws, such as Kleiber's law for metabolic rate, highlight how efficiency emerges with size across living systems. The brain, with its characteristic sublinear sc…
Probing the Microscopic Origin of Toughness in Multiple Polymer Networks
Nicholas H. P. Orr, Magali Le Goff, Burebi Yiming +6
Multiple polymer networks, such as double-network elastomers comprising a sacrificial and a matrix network, exhibit exceptional mechanical resilience, commonly attributed to the fo…
Self-organization, Memory and Learning: From Driven Disordered Systems to Living Matter
Muhittin Mungan, Eric Clement, Damien Vandembroucq +1
Disordered systems subject to a fluctuating environment can self-organize into a complex history-dependent response, retaining a memory of the driving. In sheared amorphous solids,…
Phonon Thermal Hall Effect: The Roles of Disorder, Annealing, and Metallic Contacts
Qiaochao Xiang, Xiaokang Li, Xiaodong Guo +2
The phonon thermal Hall effect (THE) is a ubiquitous yet poorly understood phenomenon in insulators. Its microscopic origin remains debated, partly due to significant sample-depend…
