Few-Shot Semantic Segmentation Meets SAM3

Yi-Jen Tsai, Yen-Yu Lin, Chien-Yao Wang ยท 2026

Few-Shot Semantic Segmentation (FSS) focuses on segmenting novel object categories from only a handful of annotated examples. Most existing approaches rely on extensive episodic training to learn tranโ€ฆ

Causality, the Kovtun-Son-Starinets bound, and a novel sum rule for spectral densities

G. Yu. Prokhorov, O. V. Teryaev ยท 2026

We directly show that the local ratio of the shear viscosity to the entropy density for Unruh radiation at a finite distance from the horizon is universal and satisfies the relation $ \eta/s = 1/(4\piโ€ฆ

Characterization of spacetime singularities for the Schr\"odinger equation by initial state

Takeru Fujii, Kenichi Ito ยท 2026

We discuss spacetime singularities of a solution to the Schr\"odinger equation with a metric perturbation and a sublinear potential. The quasi-homogeneous wave front set, due to Lascar (1977), of a soโ€ฆ

Jahn-Teller distortion on strained La$_3$Ni$_2$O$_7$ thin films

Yuxin Wang, Zhan Wang, Fu-Chun Zhang, Kun Jiang ยท 2026

We present a systematic study of the electronic structure of strained La$_3$Ni$_2$O$_7$ thin films. We show that biaxial compressive strain mainly elongates the outer apical Ni-O bond while leaving thโ€ฆ

Streaming Model Cascades for Semantic SQL

Pawe{l} Liskowski, Kyle Schmaus ยท 2026

Modern data warehouses extend SQL with semantic operators that invoke large language models on each qualifying row, but the per-row inference cost is prohibitive at scale. Model cascades reduce this cโ€ฆ
