Revisiting the Proper Motions of M31 and M33 Using Massive Supergiant Stars with Gaia DR3

Kavli Affiliate: Huawei Zhang | First 5 Authors: Hao Wu, Hao Wu, , , | Summary: The proper motions (PMs) of M31 and M33 are key to understanding the Local Group’s dynamical evolution. However, measurement discrepancies between Gaia blue and red samples, regarding whether the transverse velocity is remarkable, introduce significant ambiguity. In this work, […]

YOLO-Count: Differentiable Object Counting for Text-to-Image Generation

Kavli Affiliate: Xiang Zhang | First 5 Authors: Guanning Zeng, Guanning Zeng, , , | Summary: We propose YOLO-Count, a differentiable open-vocabulary object counting model that tackles both general counting challenges and enables precise quantity control for text-to-image (T2I) generation. A core contribution is the ‘cardinality’ map, a novel regression target that accounts for variations […]

Large phonon-drag thermopower polarity reversal in Ba-doped KTaO3

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Mohamed Nawwar, Mohamed Nawwar, , , | Summary: This study reports the observation of phonon-drag thermopower polarity reversal in Ba-doped KTaO3 thin films, mediated by electron-phonon Umklapp scattering. Epitaxial films with distinct carrier concentrations (3.7 x 10^20 cm^-3 and 4.9 x 10^19 cm^-3) were grown via […]
