Cosmogenic Neutrino Point Source and KM3-230213A

Kavli Affiliate: Zhuo Li | First 5 Authors: Qinyuan Zhang, Qinyuan Zhang, , , | Summary: Cosmogenic neutrinos (CNs) are produced by ultra-high energy cosmic rays (UHECRs) interacting with cosmic background radiation. We investigated the properties of CN point/extended sources, i.e, the neutrino spectrum, and angular profile as functions of time, by assuming that UHECR […]

A Comprehensive Study of Thermonuclear X-ray Bursts from 4U 1820-30 with NICER: Accretion Disk Interactions and a Candidate Burst Oscillation

Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: , , , , | Summary: We present the results obtained from timing and spectral studies of 15 thermonuclear X-ray bursts from 4U 1820-30 observed with the Neutron Star Interior Composition Explorer (NICER) during its five years of observations between 2017-2022. All bursts showed clear signs of […]

Rapid inference and comparison of gravitational-wave population models with neural variational posteriors

Kavli Affiliate: Salvatore Vitale | First 5 Authors: , , , , | Summary: The LIGO-Virgo-KAGRA catalog has been analyzed with an abundance of different population models due to theoretical uncertainty in the formation of gravitational-wave sources. To expedite model exploration, we introduce an efficient and accurate variational Bayesian approach that learns the population posterior […]

pH-Sensitive Optical Nanocomposites Using Polymer-Coated Gold Nanorods

Kavli Affiliate: Xingde Li | Authors: Yongping Chen and Xingde Li | Summary: This study investigates the synthesis of pH-responsive, reversible nanocomposites comprising polystyrene sulfonate (PSS)-coated gold nanorods and poly(allylamine hydrochloride) (PAH)-coated gold nanorods, along with their optical properties. We observed a pH-dependent swelling/shrinking of the nanocomposites and a dramatic red-shift (~ 60 nm) of […]

Shape My Moves: Text-Driven Shape-Aware Synthesis of Human Motions

Kavli Affiliate: Yi Zhou | First 5 Authors: Ting-Hsuan Liao, Yi Zhou, Yu Shen, Chun-Hao Paul Huang, Saayan Mitra | Summary: We explore how body shapes influence human motion synthesis, an aspect often overlooked in existing text-to-motion generation methods due to the ease of learning a homogenized, canonical body shape. However, this homogenization can distort […]

Recursive Training Loops in LLMs: How training data properties modulate distribution shift in generated data?

Kavli Affiliate: Peter Ford | First 5 Authors: Grgur Kovač, Grgur Kovač, , , | Summary: Large language models (LLMs) are increasingly used in the creation of online content, creating feedback loops as subsequent generations of models will be trained on this synthetic data. Such loops were shown to lead to distribution shifts – models […]
