Long-range inhibitory axons from medial entorhinal cortex target lateral entorhinal neurons projecting to the hippocampus

Posted by klaurent September 2, 2025September 15, 2025NTNU

Kavli Affiliate: Menno Witter | Authors: Eirik S. Nilssen, Bente Jacobsen, Thanh P. Doan, Paulo J.B. Girao and Menno P. Witter | Summary: ABSTRACT The functionally different lateral entorhinal cortex (LEC) and medial entorhinal cortex (MEC) are strongly interconnected. The role of this interconnectivity in view of their functional differences is not known. Here we […]

Topological Chiral Superconductivity in the Triangular-Lattice Hofstadter-Hubbard Model

Posted by klaurent September 2, 2025UCSB

Kavli Affiliate: Leon Balents | Summary:Moiré materials provide exciting platforms for studying the interplay of strong electronic correlation and large magnetic flux effects. We study the lightly doped Hofstadter-Hubbard model on a triangular lattice through large-scale density matrix renormalization group and determinantal quantum Monte Carlo simulations. We find strong evidence for a robust chiral superconducting […]

Coupling of a Nuclear Transition to a Surface Acoustic Wave

Posted by klaurent September 2, 2025Stanford

Kavli Affiliate: Giorgio Gratta | Summary:Mechanical modulation of recoilless nuclear transitions allows the dynamic control of $γ$-ray emission and absorption. Accessing modulation frequencies well above the nuclear linewidth enables coherent manipulation of the nuclear response. Here we demonstrate high frequency control via efficient coupling a film of enriched $^57$Fe to a $97.9~mathrmMHz$ surface acoustic wave, […]

Chemodynamics of BoötesI with $S^5$: Revised Velocity Gradient, Dark Matter Density, and Galactic Chemical Evolution Constraints

Posted by klaurent September 2, 2025September 15, 2025Chicago

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Nathan R. Sandford, Nathan R. Sandford, , , | Summary: We combine new spectroscopic observations of the ultra faint dwarf galaxy (UFD) Bo"otes I (Boo I) from the Southern Stellar Stream Spectroscopic Survey ($S^5$) with $sim$15 years of archival spectroscopic data to create the largest sample […]

PRIMA Vista: far-infrared polarimetry to unveil small-scale magnetohydrodynamics in extragalactic observations

Posted by klaurent September 2, 2025Stanford

Kavli Affiliate: Susan Clark | Summary:Magnetic fields are a fundamental part of the interstellar medium (ISM) and remain a challenge for building a comprehensive understanding of galactic properties. Their study requires far-infrared polarimetric observations, which provide an unrivaled probe of the dynamics, magnetization, and structure of the coldest and densest interstellar gas and dust at […]

AudioRWKV: Efficient and Stable Bidirectional RWKV for Audio Pattern Recognition

Posted by klaurent September 2, 2025September 15, 2025Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Jiayu Xiong, Jiayu Xiong, , , | Summary: Recently, Transformers (e.g., Audio Spectrogram Transformers, AST) and state-space models (e.g., Audio Mamba, AuM) have achieved remarkable progress in audio modeling. However, the O(L^2) computational complexity of the Transformer architecture hinders efficient long-sequence processing, while the Mamba architecture tends […]
