The paper presents an approach to efficiently detect local defect resonances (LDRs) in solids with localized defects. The 3D scanning laser Doppler vibrometry (3D SLDV) technique is applied to acquire vibration responses on the surface of a test sample due to a broadband vibration excitation applied by a piezoceramic transducer and modal shaker. Based on the response signals and known excitation, the frequency characteristics for individual response points are determined.

- Plant sterols, like stigmasterol, can lower cholesterol and improve heart health, and this research focuses on modified acylglycerols using these sterols as potential food and pharmaceutical applications.
- The study analyzes how four variations of distigmasterol-modified acylglycerols (dStigMAs) influence the fluidity and phase transition temperatures of model phospholipid membranes through various scientific techniques.
- Results show that these compounds significantly affect the physicochemical properties of the membranes, with the extent of changes influenced by the specific structure and linkers of the molecules involved.
