Universal Prompt Optimizer for Safe Text-to-Image Generation

Kavli Affiliate: Xiang Zhang | First 5 Authors: Zongyu Wu, Hongcheng Gao, Yueze Wang, Xiang Zhang, Suhang Wang | Summary: Text-to-Image (T2I) models have shown great performance in generating images based on textual prompts. However, these models are vulnerable to unsafe input to generate unsafe content like sexual, harassment and illegal-activity images. Existing studies based […]

Morphology and Mach Number Dependence of Subsonic Bondi-Hoyle Accretion

Kavli Affiliate: Lars Bildsten | First 5 Authors: Logan J. Prust, Hila Glanz, Lars Bildsten, Hagai B. Perets, Friedrich K. Roepke | Summary: We carry out three-dimensional computations of the accretion rate onto an object (of size $R_{rm sink}$ and mass $m$) as it moves through a uniform medium at a subsonic speed $v_{infty}$. The […]

Optical Control of Cell-Surface and Endomembrane-Exclusive β-Adrenergic Receptor Signaling

Kavli Affiliate: Michael W. Young | Authors: Waruna Thotamune, Sithurandi Ubeysinghe, Kendra Kumar Shrestha, Mahmoud Elhusse Mostafa, Michael C Young and Ajith Karunarathne | Summary: Beta-adrenergic receptors (βARs) are G protein-coupled receptors (GPCRs) that mediate catecholamine-induced stress responses, such as heart rate increase and bronchodilation. In addition to signals from the cell surface, βARs also […]

A Case for a Binary Black Hole System Revealed via Quasi-Periodic Outflows

Kavli Affiliate: Erin Kara | First 5 Authors: Dheeraj R. Pasham, Francesco Tombesi, Petra Sukova, Michal Zajacek, Suvendu Rakshit | Summary: Binaries containing a compact object orbiting a supermassive black hole are thought to be precursors of gravitational wave events, but their identification has been extremely challenging. Here, we report quasi-periodic variability in X-ray absorption […]

Alive but Barely Kicking: News from 3+ years of Swift and XMM-Newton X-ray Monitoring of Quasi-Periodic Eruptions from eRO-QPE1

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Dheeraj R. Pasham, Eric R. Coughlin, Michal Zajacek, Itai Linial, Petra Sukova | Summary: Quasi-periodic Eruptions (QPEs) represent a novel class of extragalactic X-ray transients that are known to repeat at roughly regular intervals of a few hours to days. Their underlying physical mechanism is a […]

Lense-Thirring Precession after a Supermassive Black Hole Disrupts a Star

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Dheeraj R. Pasham, Michal Zajacek, C. J. Nixon, Eric R. Coughlin, Marzena Sniegowska | Summary: An accretion disk formed around a supermassive black hole (SMBH) after it disrupts a star is expected to be initially misaligned with respect to the black hole’s equatorial plane. This misalignment […]
