Diagnostic Performance of Conventional Ultrasound Combined With Calcification Parameters in Soft Tissue Masses With Calcification: A Retrospective Study

Sonography, Volume 13, Issue 3, September 2026.
ABSTRACT Objective This study aimed to develop and validate an ultrasound‐based model integrating conventional ultrasound and calcification patterns (US‐CAL) for distinguishing benign from malignant calcified soft tissue masses. Methods This retrospective study analyzed 101 pathologically confirmed soft tissue masses (78 benign, 23 malignant) that ...

River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...

Characterization of Droplet Formation in Ultrasonic Spray Coating: Influence of Ink Formulation Using Phase Doppler Anemometry and Machine Learning

Advanced Materials Technologies, Volume 11, Issue 15, 7 August 2026.
This study explores how machine learning models, trained on small experimental datasets obtained via Phase Doppler Anemometry (PDA), can accurately predict droplet size (D32) in ultrasonic spray coating (USSC). By capturing the influence of ink complexity (solvent, polymer, nanoparticles), power, and flow rate, the model enables precise droplet control
