Uncovering population contributions to the extracellular potential in the mouse visual system using Laminar Population Analysis

Posted by dbos January 16, 2024January 22, 2024UCSD / Salk

Kavli Affiliate: Anders Dale | Authors: Atle Eskeland Rimehaug, Anders M. Dale, Anton Arkhipov and Gaute T. Einevoll | Summary: The local field potential (LFP), the low-frequency part of the extracellular potential, reflects transmembrane currents in the vicinity of the recording electrode. Thought mainly to stem from currents caused by synaptic input, it provides information […]

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

Posted by dbos January 16, 2024January 22, 2024Rockefeller

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, […]

The stellar Fundamental Metallicity Relation: the correlation between stellar mass, star-formation rate and stellar metallicity

Posted by dbos January 16, 2024Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Tobias J. Looser, Francesco D’Eugenio, Joanna M. Piotrowska, Francesco Belfiore, Roberto Maiolino | Summary: We present observational evidence for a stellar Fundamental Metallicity Relation (FMR), a smooth relation between stellar mass, star-formation rate (SFR) and the light-weighted stellar metallicity of galaxies (analogous to the well-established gas-phase FMR). […]

COOL-LAMPS. VII. Quantifying Strong-lens Scaling Relations with 177 Cluster-scale Gravitational Lenses in DECaLS

Posted by January 16, 2024Chicago

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Simon D. Mork, Michael D. Gladders, Gourav Khullar, Keren Sharon, Nathalie Chicoine | Summary: We compute parametric measurements of the Einstein-radius-enclosed total mass for 177 cluster-scale strong gravitational lenses identified by the ChicagO Optically-selected Lenses Located At the Margins of Public Surveys (COOL-LAMPS) collaboration with lens […]

Stochastic Inflation in General Relativity

Posted by dbos January 16, 2024Cambridge

Kavli Affiliate: E. P. S. Shellard | First 5 Authors: Yoann L. Launay, Gerasimos I. Rigopoulos, 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 […]

PPSURF: Combining Patches and Point Convolutions for Detailed Surface Reconstruction

Posted by dbos January 16, 2024Delft

Kavli Affiliate: Michael Wimmer | First 5 Authors: Philipp Erler, Lizeth Fuentes, Pedro Hermosilla, Paul Guerrero, Renato Pajarola | Summary: 3D surface reconstruction from point clouds is a key step in areas such as content creation, archaeology, digital cultural heritage, and engineering. Current approaches either try to optimize a non-data-driven surface representation to fit the […]

Hypergeometric Solutions of Linear Difference Systems

Posted by dbos January 16, 2024UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Moulay Barkatou, Mark van Hoeij, Johannes Middeke, Yi Zhou, | Summary: We extend Petkovv{s}ek’s algorithm for computing hypergeometric solutions of scalar difference equations to the case of difference systems $tau(Y) = M Y$, with $M in {rm GL}_n(C(x))$, where $tau$ is the shift operator. Hypergeometric solutions are […]
