Simultaneous, cortex-wide and cellular-resolution neuronal population dynamics reveal an unbounded scaling of dimensionality with neuron number

Posted by dbos Rockefeller

Kavli Affiliate: Alipasha Vaziri | Authors: Jason Manley, Jefferey Demas, Hyewon Kim, Francisca Martinez Traub and Alipasha Vaziri | Summary: The brain’s remarkable properties arise from collective activity of millions of neurons. Widespread application of dimensionality reduction to multi-neuron recordings implies that neural dynamics can be approximated by low-dimensional “latent” signals reflecting neural computations. However, […]

Stochastic Inflation in General Relativity

Posted by klaurent Cambridge

Kavli Affiliate: E. P. S. Shellard | Summary:We provide a formulation of Stochastic Inflation in full general relativity that goes beyond the slow-roll and separate universe approximations. We show how gauge invariant Langevin source terms can be obtained for the complete set of Einstein equations in their ADM formulation by providing a recipe for coarse-graining […]

How cytoskeletal crosstalk makes cells move: bridging cell-free and cell studies

Posted by klaurent Delft

Kavli Affiliate: Gijsje Koenderink | Summary:Cell migration is a fundamental process for life and is highly dependent on the dynamical and mechanical properties of the cytoskeleton. Intensive physical and biochemical crosstalk between actin, microtubules, and intermediate filaments ensures their coordination to facilitate and enable migration. In this review we discuss the different mechanical aspects that […]

Schrödinger cats growing up to 60 qubits and dancing in a cat scar enforced discrete time crystal

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Zehang Bao, Shibo Xu, Zixuan Song, Ke Wang, Liang Xiang | Summary: Greenberger-Horne-Zeilinger (GHZ) states, as maximally entangled Schr"{o}dinger cat states, play vital roles in the foundations of quantum physics and technology, but creating and preserving these fragile states pose tremendous challenges. Discrete time crystals (DTCs), originally […]
