Kavli Affiliate: Frank Wise | Summary:Nonlinear pulse propagation in gas-filled waveguides has attracted substantial attention over the past decade, and a variety of capabilities have been reported. However, there is no prior report of spectral compression in gas-filled waveguides or cavities, which would offer a natural route for scaling to much higher pulse energies than […]
Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:This paper addresses the problem of affordance grounding from RGBD images of an object, which aims to localize surface regions corresponding to a text query that describes an action on the object. While existing methods predict affordance regions only on visible surfaces, […]
Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:We introduce A.X K1, a 519B-parameter Mixture-of-Experts (MoE) language model trained from scratch. Our design leverages scaling laws to optimize training configurations and vocabulary size under fixed computational budgets. A.X K1 is pre-trained on a corpus of approximately 10T tokens, curated by […]
Kavli Affiliate: Brad Ramshaw | Summary:Superconductivity in three dimensions is almost universally governed by Ginzburg-Landau mean field theory, with critical fluctuations typically confined to within a few percent of the transition temperature ($T_rm c$). We report that the heavy-Fermion superconductor UTe$_2$ exhibits superconducting fluctuations that extend over a temperature range as wide as $T_rm c$ […]

Kavli Affiliate: Dwight Bergles | Authors: Dominique Meyer, Grant Kroeschell, Xiankun Lu, Linh Hoang, Haochen Wang, Shuying Li, Yu Kang T Xu, Lei Tan, Jeff S Mumm, Dwight E Bergles and Ji Yi | Summary: There is an increasing need for large-scale high-speed volumetric recording in complex multi-cellular model systems to define dynamic processes. Oblique […]
Kavli Affiliate: Boris I. Shraiman | Summary:Elasticity theory rests on a constitutive relation between stress and strain relative to a reference state. Living matter, however, generates forces by motor molecule activity independent of strain, requiring a different approach to active tissue mechanics. We develop a theory of two-dimensional continuum mechanics in which the active force […]
Kavli Affiliate: Boris I. Shraiman | Summary:A constitutive relation between stress and strain relative to a reference state is the basic assumption of elasticity theory. However, in living matter, force generation is governed by motor molecule activity, which does not depend on deformation relative to a reference. A different approach is needed to describe how […]
Kavli Affiliate: Boris I. Shraiman | Summary:A constitutive relation between stress and strain relative to a reference state is the basic assumption of elasticity theory. However, in living matter, stress is governed by (motor molecule) activity rather than a constitutive law. What paradigm takes the place of elasticity in this setting? Here, we derive a […]
