Contractivity of Multi-Stage Runge-Kutta Dynamics

This paper establishes conditions under which multi-stage Runge-Kutta methods preserve strong contractivity for infinitesimally contracting continuous-time systems, deriving coefficient-dependent criteria for explicit schemes and extending classical implicit guarantees to strong contractivity across 1\ell_1, 2\ell_2, and \ell_\infty norms while ensuring unique solvability via an auxiliary dynamic system.

Fair-Gate: Fairness-Aware Interpretable Risk Gating for Sex-Fair Voice Biometrics

The paper proposes Fair-Gate, a fairness-aware and interpretable risk-gating framework that mitigates sex-related performance gaps in voice biometrics by addressing demographic shortcut learning and feature entanglement through risk extrapolation and a local complementary routing mechanism, thereby improving the utility-fairness trade-off on the VoxCeleb1 dataset.

RHOSI: Efficient Anti-Jamming Resource Allocation with Holographic Surfaces in UAV-enabled ISAC

This paper proposes RHOSI, an efficient resource allocation framework that leverages a Reconfigurable Holographic Surface (RHS)-aided UAV to jointly optimize beamforming, phase shifts, and spatial deployment, thereby significantly enhancing the anti-jamming resilience and throughput of Integrated Sensing and Communication (ISAC) systems.

Affect Decoding in Phonated and Silent Speech Production from Surface EMG

This paper introduces a new dataset and demonstrates that surface electromyography (sEMG) signals from facial and neck muscles can reliably decode affective states, particularly frustration, during both phonated and silent speech, highlighting their potential for affect-aware silent speech interfaces.

Dimensional Scaling Laws for Continuous Fluid Antenna Systems

This paper derives asymptotically exact closed-form formulas for the high signal-to-noise ratio probability in continuous fluid antenna systems operating over Rayleigh fading channels with spatially coherent isotropic correlation, ultimately establishing scaling laws that describe performance gains across one, two, and three-dimensional spaces and identifying optimal system dimensions.
