LEO-based Positioning: Foundations, Signal Design, and Receiver Enhancements for 6G NTN

Kavli Affiliate: Feng Wang | First 5 Authors: Harish K. Dureppagari, Chiranjib Saha, Harikumar Krishnamurthy, Xiao Feng Wang, Alberto Rico-Alvariño | Summary: The integration of non-terrestrial networks (NTN) into 5G new radio (NR) has opened up the possibility of developing a new positioning infrastructure using NR signals from Low-Earth Orbit (LEO) satellites. LEO-based cellular positioning […]

Synaptic vesicle endocytosis deficits underlie GBA-linked cognitive dysfunction in Parkinson′s disease and Dementia with Lewy bodies

Kavli Affiliate: Sreeganga Chandra | Authors: D J Vidyadhara, David Backstrom, Risha Chakraborty, Jiapeng Ruan, Jae-Min Park, Pramod K. Mistry and Sreeganga S. Chandra | Summary: GBA mutations are major risk factors for Parkinson′s disease (PD) and Dementia with Lewy Bodies (DLB), two common α-synucleinopathies associated with cognitive impairment. Here, we investigated the role of […]

Coronagraph-based wavefront sensors for the high Strehl regime

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Vincent Chambouleyron, J. Kent Wallace, Rebecca Jensen-Clem, Bruce Macintosh, | Summary: A crucial component of the high-contrast instrumental chain in astronomy is the wavefront sensor (WFS). A key property of this component is its sensitivities, which reflect its ability to efficiently use incoming photons to encode the […]

Finite-Momentum Pairing State in Unconventional Rashba Systems

Kavli Affiliate: Ran Wang | First 5 Authors: Ran Wang, Song-Bo Zhang, Ning Hao, , | Summary: In systems with unconventional Rashba bands, we propose that a finite-momentum pairing state can emerge without the need for an external magnetic field. We analyze the phase transition from a zero-momentum Bardeen-Cooper-Schrieffer (BCS) state to a finite-momentum pairing […]

A measurement of atmospheric circular polarization with POLARBEAR

Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Takuro Fujino, Satoru Takakura, Shahed Shayan Arani, Darcy Barron, Carlo Baccigalupi | Summary: At millimeter wavelengths, the atmospheric emission is circularly polarized owing to the Zeeman splitting of molecular oxygen by the Earth’s magnetic field. We report a measurement of the signal in the 150 GHz band […]
