Kavli Affiliate: Kiyoshi Masui | Summary:Quantifying the maximum energy of fast radio bursts (FRBs) can provide stringent constraints on their emission mechanisms and progenitor models. However, the most energetic bursts are rare, requiring a large sample of FRBs to detect them. In this work, we use the largest available such sample, 2,998 one-off FRBs from […]
Kavli Affiliate: Herman Marshall | Summary:RCW 86 is a supernova remnant whose origin has recently been linked to an off-center explosion within a cavity created by its progenitor star. In the southwestern region, the forward shock is thought to have reached the cavity wall, encountering diverse environmental conditions. We report on the spatially resolved X-ray […]
Kavli Affiliate: David Muller | Summary:The discovery of superconductivity in square-planar nickelates has offered a rich materials platform to explore the origins of cuprate-like superconductivity. Experimental investigations however have largely been limited to the infinite-layer $R$NiO$_2$ ($R$=rare-earth) nickelates. Here, we construct a phase diagram of multi-layer square-planar Nd$_n+1$Ni$_n$O$_2n+2$ compounds and discover signatures of superconductivity for […]
Kavli Affiliate: Elena Gracheva | Authors: Shahira Helal Arzoo, Chase Drucker, Rubaia Tasmin, Nicolas Jones, Elena Gracheva, Abigail Matt, Raymond Hsin, Fei Wang, Chao Zhou and Surya Banerjee | Summary: The knock-out mutation of the unique M13 family member, the Drosophila melanogaster (fruit fly) Neprilysin-like 15 (Nepl15), resulted in marked reductions of glycogen and glycerolipid […]
Kavli Affiliate: Kenta Asahina | Authors: Donovan Ventimiglia, Elizabeth Chamiec-Case, Claire S Lee, Bruce Ruff and Kenta Asahina | Summary: Social conflict is a fundamental challenge for all animals and determines access to critical resources like mates and food. Evolutionary game theory predicts that natural selection should yield competitive strategies that balance the benefits and […]
Kavli Affiliate: Kristina Nielsen | Authors: Dallas C Khamiss, Augusto A Lempel, Brandon R Nanfito and Kristina Juliane Nielsen | Summary: A fundamental aspect of visual motion processing is the computation of motion direction. In ferrets, as in primates, selectivity for motion direction is found both in early cortical stages like the primary visual cortex […]
Kavli Affiliate: Wei Gao| Summary:Millimeter-wave Human Pose Estimation (mmWave HPE) promises privacy but suffers from poor generalization under distribution shifts. We demonstrate that brute-force data scaling is ineffective for out-of-distribution (OOD) robustness; efficiency and coverage are the true bottlenecks. To address this, we introduce WiCompass, a coverage-aware data-collection framework. WiCompass leverages large-scale motion-capture corpora to […]
Kavli Affiliate: Marina Picciotto | Authors: WenLiang Zhou, Hanna Yousuf, Yann S Mineur and Marina Picciotto | Summary: Activity of the mesolimbic system is essential for adaptive performance of reward-related behaviors. Within this system, dopaminergic (DAergic) neurons play a critical role in driving motivation to obtain rewards and encoding predictions and error signals during reinforcement […]
Kavli Affiliate: Roger Romani | Summary:We present X-ray proper motion (PM) measurements of 19 pulsars using new and archival data from the Chandra X-ray Observatory, including pulsar wind trails and X-ray filaments. Precise X-ray PMs are often limited by uncertainties in aligning observations to a common reference frame. Our analysis uses unresolved X-ray flux from […]
Kavli Affiliate: Leonardo Dicarlo | Summary:We investigate qubit error bursts in 5- and 7-transmon processors of similar design, fabrication and packaging, but with different types of qubit Josephson junctions. Measurements for each are performed in two refrigerators to discern device-specific from refrigerator-dependent characteristics. The duration and rate of bursts are device specific but within the […]
