Scaling User Modeling: Large-scale Online User Representations for Ads Personalization in Meta

Kavli Affiliate: Yi Zhou | First 5 Authors: Wei Zhang, Dai Li, Chen Liang, Fang Zhou, Zhongke Zhang | Summary: Effective user representations are pivotal in personalized advertising. However, stringent constraints on training throughput, serving latency, and memory, often limit the complexity and input feature set of online ads ranking models. This challenge is magnified […]

Project Dinos I: A joint lensing-dynamics constraint on the deviation from the power law in the mass profile of massive ellipticals

Kavli Affiliate: Elizabeth Buckley-Geer | Summary:The mass distribution in massive elliptical galaxies encodes their evolutionary history, thus providing an avenue to constrain the baryonic astrophysics in their evolution. The power-law assumption for the radial mass profile in ellipticals has been sufficient to describe several observables to the noise level, including strong lensing and stellar dynamics. […]

BPS Fivebrane Stars II: Fluctuations

Kavli Affiliate: Emil J. Martinec | First 5 Authors: Emil J. Martinec, Yoav Zigdon, , , | Summary: We investigate quantum fluctuations of metric components in coherent 1/2-BPS bound states of $n_1$ fundamental strings and $n_5$ NS5-branes. The leading order contribution in an expansion in $1/(n_1n_5)$ is calculated via a combination of analytical and numerical […]

BPS Fivebrane Stars I: Expectation Values of Observables

Kavli Affiliate: Emil J. Martinec | First 5 Authors: Emil J. Martinec, Yoav Zigdon, , , | Summary: We study ensembles of 1/2-BPS bound states of fundamental strings and NS-fivebranes (NS5-F1 states) in the AdS decoupling limit. We revisit a solution corresponding to an ensemble average of these bound states, and find that the appropriate […]

Josephson Diode Effect in Topological Superconductor

Kavli Affiliate: Jing Wang | First 5 Authors: Zhaochen Liu, Linghao Huang, Jing Wang, , | Summary: We investigate the Josephson diode effect (JDE) in topological Josephson junctions. By both analytic and numerical calculations, we find that while a Josephson junction in the topological phase may exhibit higher diode efficiency compared to that in the […]

Kavli Affiliate: Jing Wang | First 5 Authors: Zhaochen Liu, Linghao Huang, Jing Wang, , | Summary: We investigate the Josephson diode effect in topological Josephson junctions. We find that while a Josephson junction in the topological phase may exhibit higher diode efficiency compared to that in the trivial phase, this behavior is not universal. […]
