Quantum initial conditions for curved inflating universes

Kavli Affiliate: Anthony Lasenby | Summary:We discuss the challenges of motivating, constructing, and quantizing a canonically normalized inflationary perturbation in spatially curved universes. We show that this has historically proved challenging due to the interaction of nonadiabaticity with spatial curvature. We construct a novel curvature perturbation that is canonically normalized in the sense of its […]

Background Determination for the LUX-ZEPLIN (LZ) Dark Matter Experiment

Kavli Affiliate: C. M. Ignarra | Summary:The LUX-ZEPLIN experiment recently reported limits on WIMP-nucleus interactions from its initial science run, down to $9.2times10^-48$ cm$^2$ for the spin-independent interaction of a 36 GeV/c$^2$ WIMP at 90% confidence level. In this paper, we present a comprehensive analysis of the backgrounds important for this result and for other […]

The role of non-affine deformations in the elastic behavior of the cellular vertex model

Kavli Affiliate: Mark J. Bowick | First 5 Authors: Michael F. Staddon, Arthur Hernandez, Mark J. Bowick, Michael Moshe, M. Cristina Marchetti | Summary: The vertex model of epithelia describes the apical surface of a tissue as a tiling of polygonal cells, with a mechanical energy governed by deviations in cell shape from preferred, or […]

Electron Dynamics at High-Energy Densities in Nickel from Non-linear Resonant X-ray Absorption Spectra

Kavli Affiliate: Robert Rosner| First 5 Authors: Robin Y. Engel, Robin Y. Engel, , , | Summary:The pulse intensity from X-ray free-electron lasers (FELs) can create extreme excitation densities in solids, entering the regime of non-linear X-ray-matter interactions. We show L3-edge absorption spectra of metallic nickel thin films with fluences entering a regime where several […]

Violation of the ultrastructural size principle in the dorsolateral prefrontal cortex underlies working memory impairment in the aged common marmoset (Callithrix jacchus)

Kavli Affiliate: John Reynolds | Authors: Courtney Glavis-Bloom, Casey R Vanderlip, Sammy Weiser Novak, Masaaki Kuwajima, Lyndsey Kirk, Uri Manor, Kristen M Harris and John H Reynolds | Summary: ABSTRACT Working memory relies critically on the dorsolateral prefrontal cortex (dlPFC). Morphology and function of the dlPFC, and corresponding working memory performance, are affected early in […]

Generative network modeling reveals quantitative definitions of bilateral symmetry exhibited by a whole insect brain connectome

Kavli Affiliate: Carey Priebe, Joshua Vogelstein | Authors: Benjamin D. Pedigo, Mike Powell, Eric W. Bridgeford, Michael Winding, Carey E. Priebe and Joshua T. Vogelstein | Summary: Abstract Comparing connectomes can help explain how neural connectivity is related to genetics, disease, development, learning, and behavior. However, making statistical inferences about the significance and nature of […]

Predicting pathways for old and new metabolites through clustering

Kavli Affiliate: Nathan Lewis | Summary:The diverse metabolic pathways are fundamental to all living organisms, as they harvest energy, synthesize biomass components, produce molecules to interact with the microenvironment, and neutralize toxins. While discovery of new metabolites and pathways continues, the prediction of pathways for new metabolites can be challenging. It can take vast amounts […]

Null controllability of damped nonlinear wave equation

Kavli Affiliate: Yi Zhou | First 5 Authors: Yan Cui, Yan Cui, , , | Summary: In this paper, we investigate the null controllability of nonlinear wave systems. Initially, we employ a combination of the Galerkin method and a fixed point theorem to establish the null controllability for semi-linear wave equations with nonlinear functions that […]
