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 […]

The DECam MAGIC Survey: A Wide-field Photometric Metallicity Study of the Sculptor Dwarf Spheroidal Galaxy

Kavli Affiliate: Alexander Ji | First 5 Authors: Fabrícia O. Barbosa, Anirudh Chiti, Guilherme Limberg, Andrew Pace, William Cerny | Summary: The metallicity distribution function and internal chemical variations of a galaxy are fundamental to understand its formation and assembly history. In this work, we analyze photometric metallicities for 3883 stars over seven half-light radii […]

HumanDreamer-X: Photorealistic Single-image Human Avatars Reconstruction via Gaussian Restoration

Kavli Affiliate: Zheng Zhu | First 5 Authors: Boyuan Wang, Runqi Ouyang, Xiaofeng Wang, Zheng Zhu, Guosheng Zhao | Summary: Single-image human reconstruction is vital for digital human modeling applications but remains an extremely challenging task. Current approaches rely on generative models to synthesize multi-view images for subsequent 3D reconstruction and animation. However, directly generating […]
