Kavli Affiliate: Steven Allen | Summary:This study aims to improve the directional sensitivity of magnetic resonance hydrophone (MRH) methods and allow for detection and quantification of waves traveling at any angle relative to the MRI bore-axis. Doing so may better integrate MRH technology into transcranial focused ultrasound neuromodulation therapies. Existing MRH implementations only encode acoustic […]
Kavli Affiliate: Robert Simcoe | Summary:We report the serendipitous discovery of a dense, metal-enriched circumgalactic medium (CGM) absorber at z=7.03, together with its host galaxy, identified along the sightline toward a red quasar. The absorber exhibits the largest rest-frame equivalent widths and column densities observed to date at z>5, tracing a metal-enriched gaseous halo. Using […]
Kavli Affiliate: Kenneth Miller | Authors: Yue Kris Wu and Kenneth D Miller | Summary: Paradoxical responses, in which excitatory perturbations of inhibitory neurons reduce their firing rates, are widely regarded as a hallmark of inhibition-stabilized networks (ISNs) and have been observed in multiple brain regions. However, because brain regions are interconnected by long-range projections, […]

Edwards, Priyamvada Acharya and Maolin Lu | Summary: Peptide fusion inhibitors, an important class of antivirals, block viral entry by targeting fusion proteins required for […]

Kavli Affiliate: Luis Ho | Summary:Reliable catalogs at the faint limit are essential for statistical studies of galaxy evolution. However, detection and structural measurements of faint galaxies remain challenging. We evaluate detection completeness and structural parameter uncertainties of faint galaxies in the CANDELS/EGS field using mock images and observations from the HST and JWST. The […]
Kavli Affiliate: Nergis Mavalvala | Summary:Strong $χ^(2)$ interactions at low optical powers are key to scalable nonlinear and quantum photonics. Although doubly resonant microresonators exhibit exceptional efficiencies, they require simultaneous resonance and phase matching of widely separated optical frequencies, making them inherently sensitive to fabrication and operating conditions. Singly resonant cavities eliminate this constraint by […]
Kavli Affiliate: Michael Roukes | Summary:Mechanical frequency-shift sensors have never reached their fundamental thermomechanical or quantum limits. Every material, size, and transduction scheme yet examined yields a $1/f$ floor 1-3 orders higher, with a flicker-noise coefficient $h_-1 propto 1/V_varepsilon$. Surveying the published record, I find the invariant $h_-1,V_varepsilon equiv σ_A ^2, V_varepsilon/(2ln 2)$ independent of […]
Kavli Affiliate: Ruobing Dong | Summary:Spatially resolved dust rings in protoplanetary disks are widely used to infer disk and dust physics from multi-wavelength continuum observations. Their interpretation, however, often neglects grain growth and the evolution of the size distribution, limiting the connection between observed ring profiles and dust-evolution parameters. Building on a physical dust-ring model […]
Kavli Affiliate: Irfan Siddiqi | Summary:Flux-activated two-qubit gates in superconducting processors require correction of line distortion, which otherwise produces residual detuning, conditional-phase error, and leakage. Prior demonstrations of cryoscope-based distortion calibration have generally used commercial solutions that specify the filter models but not their FPGA implementation. These details matter for custom and open-source systems, where […]
