JWST-TST DREAMS: Sulfur dioxide in the atmosphere of the Neptune-mass planet HAT-P-26 b from NIRSpec G395H transmission spectroscopy

Posted by klaurent MIT

Kavli Affiliate: Sara Seager | Summary:We present the James Webb Space Telescope (JWST) transmission spectrum of the exoplanet HAT-P-26 b (18.6 Earth masses, 6.33 Earth radii), based on a single transit observed with the JWST NIRSpec G395H grating. We detect water vapor (ln B = 4.1), carbon dioxide (ln B = 85.6), and sulfur dioxide […]

Fine-Tuning Large Multimodal Models for Automatic Pronunciation Assessment

Posted by klaurent Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Ke Wang, , , | Summary: Automatic Pronunciation Assessment (APA) is critical for Computer-Assisted Language Learning (CALL), requiring evaluation across multiple granularities and aspects. Large Multimodal Models (LMMs) present new opportunities for APA, but their effectiveness in fine-grained assessment remains uncertain. This work investigates fine-tuning […]

MS-GS: Multi-Appearance Sparse-View 3D Gaussian Splatting in the Wild

Posted by klaurent UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Deming Li, Deming Li, , , | Summary: In-the-wild photo collections often contain limited volumes of imagery and exhibit multiple appearances, e.g., taken at different times of day or seasons, posing significant challenges to scene reconstruction and novel view synthesis. Although recent adaptations of Neural Radiance Field […]

Detail Across Scales: Multi-Scale Enhancement for Full Spectrum Neural Representations

Posted by klaurent UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Yuan Ni, Yuan Ni, , , | Summary: Implicit neural representations (INRs) have emerged as a compact and parametric alternative to discrete array-based data representations, encoding information directly in neural network weights to enable resolution-independent representation and memory efficiency. However, existing INR approaches, when constrained to compact […]

Methylphenidate-induced reductions in choice impulsivity are associated with alterations in cortico-striatal beta oscillations.

Posted by dbos UCSD / Salk

Kavli Affiliate: Dhakshin Ramanathan | Authors: Jason Nan, Alyssa J Terry, Noelle Lee, Morteza Salimi, Reyana Menon, Sam A Barnes, Dhakshin S Ramanathan and Miranda Francoeur Koloski | Summary: Impulsive choice- preferring small, immediate rewards over larger, delayed reward- is a hallmark of many psychiatric disorders. Methylphenidate, a dopamine and noradrenaline transporter inhibitor, reduces impulsivity, […]

Low-energy nuclear recoil calibration of the LUX-ZEPLIN experiment with a photoneutron source

Posted by klaurent Stanford

Kavli Affiliate: Daniel Akerib| First 5 Authors: J. Aalbers, J. Aalbers, , , | Summary:The LZ experiment is a liquid xenon time-projection chamber (TPC) searching for evidence of particle dark matter interactions. In the simplest assumption of elastic scattering, many dark matter models predict an energy spectrum which rises quasi-exponentially with decreasing energy transfer to […]

Internal and external contexts drive distinct dynamics in shared action-encoding striatal neurons

Posted by dbos Columbia

Kavli Affiliate: Rui Costa | Authors: Tanya Sippy, Jan L. Klee, Sulekh Fernando-Peiris, Sahil Suresh, Ines Rodrigues-Vaz, Rui M. Costa and Vivek R. Athalye | Summary: Animals can flexibly initiate actions guided by external cues or by internal drive. Disease states often disrupt cue-driven and self-paced actions in distinct ways, underscoring separable neural mechanisms. Such […]
