Capturing electronic correlations in electron-phonon interactions in molecular systems with the GW approximation

Posted by dbos March 13, 2024March 25, 2024Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Antonios M. Alvertis, David B. Williams-Young, Fabien Bruneval, Jeffrey B. Neaton, | Summary: Electron-phonon interactions are of great importance to a variety of physical phenomena, and their accurate description is an important goal for first-principles calculations. Isolated examples of materials and molecular systems have emerged where […]

Iterative Learning for Joint Image Denoising and Motion Artifact Correction of 3D Brain MRI

Posted by dbos March 13, 2024March 25, 2024Caltech

Kavli Affiliate: Lihong Wang | First 5 Authors: Lintao Zhang, Mengqi Wu, Lihong Wang, David C. Steffens, Guy G. Potter | Summary: Image noise and motion artifacts greatly affect the quality of brain MRI and negatively influence downstream medical image analysis. Previous studies often focus on 2D methods that process each volumetric MR image slice-by-slice, […]

Automated discovery of reprogrammable nonlinear dynamic metamaterials

Posted by dbos March 12, 2024Harvard

Kavli Affiliate: Katia Bertoldi | First 5 Authors: Giovanni Bordiga, Eder Medina, Sina Jafarzadeh, Cyrill Boesch, Ryan P. Adams | Summary: Harnessing the rich nonlinear dynamics of highly-deformable materials has the potential to unlock the next generation of functional smart materials and devices. However, unlocking such potential requires effective strategies to spatially design optimal material […]

EIGER VI. The Correlation Function, Host Halo Mass and Duty Cycle of Luminous Quasars at $zgtrsim6$

Posted by dbos March 12, 2024MIT

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Anna-Christina Eilers, Ruari Mackenzie, Elia Pizzati, Jorryt Matthee, Joseph F. Hennawi | Summary: We expect luminous ($M_{1450}lesssim-26.5$) high-redshift quasars to trace the highest density peaks in the early universe. Here, we present observations of four $zgtrsim6$ quasar fields using JWST/NIRCam in imaging and widefield slitless spectroscopy […]

EIGER VI. The Correlation Function, Host Halo Mass and Duty Cycle of Luminous Quasars at $zgtrsim6$

Posted by dbos March 12, 2024March 25, 2024MIT

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Anna-Christina Eilers, Ruari Mackenzie, Elia Pizzati, Jorryt Matthee, Joseph F. Hennawi | Summary: We expect luminous ($M_{1450}lesssim-26.5$) high-redshift quasars to trace the highest density peaks in our universe, and therefore to reside in proto-clusters encompassing an abundance of galaxies in close vicinity. Here, we present observations […]

Modulation of GABAA receptor trafficking by WWC2 reveals class-specific mechanisms of synapse regulation by WWC family proteins

Posted by dbos March 12, 2024March 25, 2024Hopkins

Kavli Affiliate: Richard Huganir | Authors: Thomas L Dunham, Julia R Wilkerson, Richard C Johnson, Richard L. Huganir and Lenora J Volk | Summary: WWC2 (WW and C2 domain-containing protein) is implicated in several neurological disorders, however its function in the brain has yet to be determined. Here, we demonstrate that WWC2 interacts with inhibitory […]
