Sparse array 3D ultrasound imaging
Sparse arrays present several notable advantages over other element reduction techniques for 3D ultrasound imaging. One of the most promising benefits is their ability to freely steer the ultrasound beam in all directions, which significantly enlarges the field of view. This capability opens up possibilities for implementing advanced imaging sequences,

The Role of Certifications in Improving Household Food Security Among Peruvian Farmers
ABSTRACT Achieving global food security requires sustainable transformations in agri‐food systems. Voluntary Sustainability Standards (VSS) such as Organic and Fairtrade aim to internalize certain social and environmental costs while promoting more equitable value distribution, improved market access, and sustainable production practices.

Trust‐region filter algorithms utilizing Hessian information for gray‐box optimization
Abstract Optimizing industrial processes often involves gray‐box models that couple algebraic glass‐box equations with black‐box components lacking analytic derivatives. Such systems challenge derivative‐based solvers. The classical trust‐region filter (TRF) algorithm provides a robust framework but requires extensive parameter tuning and numerous ...
