Kavli Affiliate: David N. Spergel | First 5 Authors: Jacob Nibauer, Jacob Nibauer, , , | Summary: Stellar streams are sensitive tracers of low-mass dark matter subhalos and provide a means to test the Cold Dark Matter (CDM) paradigm on small scales. In this work, we connect the intrinsic velocity dispersion of the GD-1 stream […]
Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Kentaro Kasai, Kentaro Kasai, , , | Summary: The existence of a large primordial neutrino asymmetry is an intriguing possibility, both observationally and theoretically. Such an asymmetry can lead to the resonant production of $mathrmkeV$-scale sterile neutrinos, which are a fascinating candidate for dark matter. In this […]
Kavli Affiliate: Ran Wang | First 5 Authors: Guoping Liu, Guoping Liu, , , | Summary: We study the bi-parameter local linearization of the one-dimensional nonlinear stochastic wave equation driven by a Gaussian noise, which is white in time and has a spatially homogeneous covariance structure of Riesz-kernel type. We establish that the second-order increments […]
Kavli Affiliate: Zheng Zhu | First 5 Authors: Angen Ye, Angen Ye, , , | Summary: Vision-Language-Action (VLA) models aim to unify perception, language understanding, and action generation, offering strong cross-task and cross-scene generalization with broad impact on embodied AI. However, current VLA models often lack explicit step-by-step reasoning, instead emitting final actions without considering […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Haokun Zhao, Haokun Zhao, , , | Summary: Time series forecasting is central to decision-making in domains as diverse as energy, finance, climate, and public health. In practice, forecasters face thousands of short, noisy series that vary in frequency, quality, and horizon, where the dominant cost lies […]
Kavli Affiliate: David A. Muller | First 5 Authors: Desheng Ma, Desheng Ma, , , | Summary: Tilt-corrected imaging methods in four-dimensional scanning transmission electron microscopy (4D-STEM) have recently emerged as a new class of direct ptychography methods that are especially useful at low dose. The operation of tilt correction unfolds the contrast transfer functions […]
Kavli Affiliate: Noah Kurinsky | First 5 Authors: Jadyn Anczarski, Jadyn Anczarski, , , | Summary: The SPLENDOR Collaboration studies novel narrow-gap semiconductors and engineered a substrate agnostic detector platform to achieve $mathcalO$(meV) energy sensitivity designed for low mass dark matter searches. This was achieved using low-capacitance and low-noise commercial CryoHEMTs in a split-stage topology […]
Kavli Affiliate: Rafael Nunez | Authors: Pieter van Dillewijn, Lydia M. Bernabéu-Roda, Virginia Cuéllar, Rafael Núñez, Otto Geiger, Isabel M. López-Lara and María J. Soto | Summary: Bacterial volatile compounds play important roles in intra- and interkingdom interactions but very little is known about their effects on soil and plant microbiomes. The legume symbiont Sinorhizobium […]
Kavli Affiliate: Anastasia Kiyonaga | Authors: Yueying Dong, Yunchen Hung, Lana Gaspariani and Anastasia Kiyonaga | Summary: Working memory (WM) representations may be more action-oriented and anatomically widespread than previously assumed. For instance, oculomotor signatures like gaze biases can reflect spatial WM content. However, the specificity and functional relevance of such signatures is unclear. Here, […]
Kavli Affiliate: Marshall Hussain Shuler | Authors: Elissa Sutlief, Shichen Zhang, Kate Forsberg, Rie Kaneko and Marshall G Hussain Shuler | Summary: Activities with diminishing returns pose a unique computational problem for the brain, requiring a combination of outcome evaluation and temporal tracking. Deciding the right time to stop one pursuit and move to alternatives […]
