Using Annular Array Pulse-Echo Ultrasound Toward High Resolution Local Speed of Sound Estimation
IEEE Open Journal of Instrumentation and MeasurementAccurate local speed of sound (SoS) estimation is crucial for medical applications, such as tissue characterization and thermal therapy monitoring. Conventional linear arrays suffer from poor out-of-plane focusing, leading to increased deviations and ...

Learned Conformational Space and Pharmacophore Into Molecular Foundational Model
Advanced Science, EarlyView.The Ouroboros model introduces two orthogonal modules within a unified framework that independently learn molecular representations and generate chemical structures. This design enables flexible optimization strategies for each module and faithful structure reconstruction without prompts or noise.

Solid Harmonic Wavelet Bispectrum for Image Analysis
Advanced Science, EarlyView.The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,
