PromptEnhancer: A Simple Approach to Enhance Text-to-Image Models via Chain-of-Thought Prompt Rewriting

Posted by klaurent Peking

Kavli Affiliate: Li Xin Li | First 5 Authors: Linqing Wang, Linqing Wang, , , | Summary: Recent advancements in text-to-image (T2I) diffusion models have demonstrated remarkable capabilities in generating high-fidelity images. However, these models often struggle to faithfully render complex user prompts, particularly in aspects like attribute binding, negation, and compositional relationships. This leads […]

Optical Fiber-Waveguide Hybrid Architecture for Mid-Infrared Ring Lasers

Posted by klaurent UCAS

Kavli Affiliate: Long Zhang | First 5 Authors: Tinghui An, Tinghui An, , , | Summary: We report a mid-infrared ring laser via fiber-to-waveguide hybrid integration enabled by directional couplers fabricated in fluoride glasses. Directional couplers were inscribed into fluoride glass using femtosecond laser direct writing, forming low-loss waveguides with a high positive refractive index […]

Visible Yet Unreadable: A Systematic Blind Spot of Vision Language Models Across Writing Systems

Posted by klaurent Berkeley

Kavli Affiliate: Ting Xu | First 5 Authors: Jie Zhang, Jie Zhang, , , | Summary: Writing is a universal cultural technology that reuses vision for symbolic communication. Humans display striking resilience: we readily recognize words even when characters are fragmented, fused, or partially occluded. This paper investigates whether advanced vision language models (VLMs) share […]

Integrated photonic ultrawideband real-time spectrum sensing for 6G wireless networks

Posted by klaurent Peking

Kavli Affiliate: Feng Yuan | First 5 Authors: Yuansheng Tao, Yuansheng Tao, , , | Summary: The sixth generation (6G) wireless networks require dynamic spectrum management to optimize the utilization of scarce spectral resources and support emerging integrated sensing and communication (ISAC) applications. This necessitates real-time spectrum sensing (RT-SS) capability with ultrawide measurement range, compact […]

The Spin-orbit alignment of two short period eclipsing binary systems

Posted by klaurent MIT

Kavli Affiliate: Avi Shporer | First 5 Authors: Tony Wells, Tony Wells, , , | Summary: We present a joint analysis of TESS photometry and radial velocity measurements obtained from the Minerva-Australis facility for two short-period eclipsing binaries, TIC 48227288 and TIC 339607421. TIC 339607421 hosts an M-dwarf companion ($M_B = 0.294 pm 0.013 : […]

Search for low-mass electron-recoil dark matter using a single-charge sensitive SuperCDMS-HVeV Detector

Posted by klaurent Stanford

Kavli Affiliate: D. B. Macfarlane | First 5 Authors: SuperCDMS Collaboration, SuperCDMS Collaboration, , , | Summary: We present constraints on low mass dark matter-electron scattering and absorption interactions using a SuperCDMS high-voltage eV-resolution (HVeV) detector. Data were taken underground in the NEXUS facility located at Fermilab with an overburden of 225 meters of water […]

The clustering of C IV and Si IV at the end of reionisation: A perspective from the E-XQR-30 survey

Posted by klaurent Cambridge

Kavli Affiliate: Martin Haehnelt | First 5 Authors: Louise Welsh, Louise Welsh, , , | Summary: We aim to study the clustering of metal absorption lines and the structures that they arise in as a function of cosmic time. We focus on C IV and Si IV absorption features that are identified along a given […]
