Navigating the Maze: Identifying Potential Pitfalls in Attention State Classification from fMRI Brain Patterns

Posted by dbos Hopkins

Kavli Affiliate: David Linden | Authors: Ruben Andreas Bressler, Assunta Ciarlo, Sophie Raible, Giancarlo Valente, Michael Lührs, Ralph Tier, David E Linden and Rainer Goebel | Summary: Multi-voxel pattern analysis (MVPA) is a powerful technique to decode brain states from functional magnetic resonance imaging (fMRI) activity patterns. In neurofeedback (NF) applications, it has been used […]

Bulge Oscillation Driven by Outflows of Active Galactic Nuclei. I. Fast Outflow Case

Posted by dbos Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Yue-Chang Peng, Jian-Min Wang, Yu Zhao, Luis C. Ho, | Summary: There is growing evidence for star formation inside outflows of active galactic nuclei (AGNs). The formed stars are injected into bulges and give rise to perturbation of bulges. In this paper, we investigate the issues […]

Meson correlators in 4d $mathcal{N}=2$ SCFTs and hints for 8d structures at weak coupling

Posted by dbos UCAS

Kavli Affiliate: Xinan Zhou | First 5 Authors: Xi-Er Du, Zhongjie Huang, Bo Wang, Ellis Ye Yuan, Xinan Zhou | Summary: We study correlators of $frac{1}{2}$-BPS mesons in two examples of 4d SQCDs with $mathcal{N}=2$ superconformal symmetry in the planar limit. We focus on the weakly coupled regime and obtain one-loop corrections to $n$-point meson […]

Picosecond expansion in LaAlO3 resonantly driven by infrared-active phonons

Posted by dbos Cornell

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Jakob Gollwitzer, Jeffrey Z. Kaaret, Y. Eren Suyolcu, Guru Khalsa, Rylan C. Fernandes | Summary: We investigate the ultrafast structural dynamics of LaAlO3 thin films driven by short mid-infrared laser pulses at 20 THz. Time-resolved X-ray diffraction reveals an immediate lattice expansion and an acoustic breathing […]

Gene regulatory networks and essential transcription factors for de novo originated genes

Posted by dbos Rockefeller

Kavli Affiliate: Li Zhao | Authors: Junhui Peng, Bing-Jun Wang, Nicolas Svetec and Li Zhao | Summary: The regulation of gene expression is crucial for the functional integration of evolutionarily young genes, particularly those that emerge de novo. However, the regulatory programs governing the expression of de novo genes remain unknown. To address this, we […]

A tensor network formulation of Lattice Gauge Theories based only on symmetric tensors

Posted by dbos Delft

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Manu Canals, Natalia Chepiga, Luca Tagliacozzo, , | Summary: The Lattice Gauge Theory Hilbert space is divided into gauge-invariant sectors selected by the background charges. Such a projector can be directly embedded in a tensor network ansatz for gauge-invariant states as originally discussed in [Phys. Rev. B […]

3D Radiative MHD Simulations of Starspots II: Large-scale Structure

Posted by dbos Stanford

Kavli Affiliate: Robert Cameron | First 5 Authors: Tanayveer Singh Bhatia, Mayukh Panja, Robert Cameron, Sami Solanki, | Summary: We compute realistic 3D radiative MHD near-surface models of starspots with substantial penumbrae on cool main-sequence stars using the MURaM simulation code. This work is an improvement on the the previous starspot models in a slab […]

The Interplay Between Electron Localization, Magnetic Order, and Jahn-Teller Distortion that Dictates LiMnO$_2$ Phase Stability

Posted by dbos Berkeley

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Ronald L. Kam, Luca Binci, Aaron D. Kaplan, Kristin A. Persson, Nicola Marzari | Summary: The development of Mn-rich cathodes for Li-ion batteries promises to alleviate supply chain bottlenecks in battery manufacturing. Challenges in Mn-rich cathodes arise from Jahn-Teller (JT) distortions of Mn$^{3+}$, Mn migration, and […]
