Multi-state calibration of a dual VI sensor for microsecond-level impedance measurement in plasma systems

This paper presents a multi-state calibration for a dual Voltage-Current (VI) sensor system designed for real-time impedance measurement in plasma applications. The proposed approach addresses key limitations of conventional VI sensors, including susceptibility to parasitic effects, and impractical calibration routines...

$\tau_0$-VLA: a Hierarchical Robot Foundation Model with World-Model-Guided Test-Time Computation

Across in-domain and distribution-shifted settings, allocating additional test-time computation substantially improves next-subtask prediction accuracy, and these gains translate into higher closed-loop success on long-horizon robot manipulation tasks.
