Forecasting subcritical cylinder wakes with Fourier Neural Operators

Kavli Affiliate: Morteza Gharib | First 5 Authors: Peter I Renn, Cong Wang, Sahin Lale, Zongyi Li, Anima Anandkumar | Summary: We apply Fourier neural operators (FNOs), a state-of-the-art operator learning technique, to forecast the temporal evolution of experimentally measured velocity fields. FNOs are a recently developed machine learning method capable of approximating solution operators […]

Hippocampal area CA2 controls seizure dynamics, interictal EEG abnormalities and social comorbidity in mouse models of temporal lobe epilepsy

Kavli Affiliate: Steven Siegelbaum | Authors: Christos Panagiotis Lisgaras, Azahara Oliva, Sam Mckenzie, John LaFrancois, Steven A. Siegelbaum and Helen E. Scharman | Summary: Temporal lobe epilepsy (TLE) is characterized by spontaneous recurrent seizures, abnormal activity between seizures, and impaired behavior. CA2 pyramidal neurons (PNs) are potentially important because inhibiting them with a chemogenetic approach […]

What Causes The Formation of Disks and End of Bursty Star Formation?

Philip F. Hopkins, Alexander B. Gurvich, Xuejian Shen, Zachary Hafen, Michael Y. Grudic | Summary: [[{“value”:”As they grow, galaxies can transition from irregular/spheroidal with ‘bursty’ star formation histories (SFHs), to disky with smooth SFHs. But even in simulations, the direct physical cause of such transitions remains unclear. We therefore explore this in a large suite […]

Characterization of a set of small planets with TESS and CHEOPS and an analysis of photometric performance

Kavli Affiliate: Sara Seager | First 5 Authors: Dominic Oddo, Diana Dragomir, Alexis Brandeker, Hugh P. Osborn, Karen Collins | Summary: The radius valley carries implications for how the atmospheres of small planets form and evolve, but this feature is visible only with highly precise characterizations of many small planets. We present the characterization of […]

Three-dimensional integration enables ultra-low-noise, isolator-free Si photonics

Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Chao Xiang, Warren Jin, Osama Terra, Bozhang Dong, Heming Wang | Summary: While photonic integrated circuits (PICs) are being widely used in applications such as telecommunications and datacenter interconnects, PICs capable of replacing bulk optics and fibers in high-precision, highly-coherent applications will require ultra-low-noise laser sources […]

Probing the interplay between jets, winds and multi-phase gas in 11 radio-quiet PG Quasars: A uGMRT-VLA study

Kavli Affiliate: Luis C. Ho | First 5 Authors: Silpa S., P. Kharb, Luis C. Ho, C. M. Harrison, | Summary: We present polarization-sensitive images from the Karl G. Jansky Very Large Array (VLA) at 5 GHz of 11 radio-quiet PG quasars. Based on the radio morphology, spectral index and polarization properties from the VLA […]

Quadratic-soliton-enhanced mid-IR molecular sensing

Kavli Affiliate: Alireza Marandi | First 5 Authors: Robert M. Gray, Mingchen Liu, Selina Zhou, Arkadev Roy, Luis Ledezma | Summary: Optical solitons have long been of interest both from a fundamental perspective and because of their application potential. Both cubic (Kerr) and quadratic nonlinearities can lead to soliton formation, but quadratic solitons can practically […]
