A stress‐balance‐based critical Weber number for droplets and bubbles

AIChE Journal, EarlyView.
Abstract Predicting droplet and bubble breakup in turbulent flows is critical for optimizing multiphase flow processes such as emulsification and atomization. Traditional models based on a fixed critical Weber number (Wec$$ {We}_c $$) may not capture interfacial‐stress dominance in low‐viscosity fluids or viscous resistance in high‐viscosity droplets ...

HeaTrace: A Parametric Design‐to‐Fabrication Workflow for Thermally Programmable Soft Robots

Advanced Intelligent Systems, EarlyView.
A programmable thermal actuation workflow enables soft robots to be designed and fabricated with embedded heaters that drive multiple responses. By combining performance‐driven heater design with multimaterial fabrication, the system supports thermally triggered shape change, stiffness tuning, and thermochromic visual response, as demonstrated through ...

Food inflation pass‐through from agricultural imports in a small open economy

American Journal of Agricultural Economics, EarlyView.
Abstract This paper develops a new framework for quantifying cost pass‐through in a small open economy by estimating firm‐level markup responses to agricultural import price shocks. We show theoretically that markup adjustments depend on firms' reliance on imported inputs and demand curvature, generating heterogeneous inflationary effects across firm ...

Lost in aggregation? On the importance of local food price data for food poverty estimates

American Journal of Agricultural Economics, EarlyView.
Abstract This paper explores within‐country variations in food price dynamics and food poverty estimates by employing local market price data and national consumer price index (CPI) data. Our results show that national CPI data may be useful for approximating national trends but they fail to detect and identify spatial variations in local trends, which

Occupational Exposure to Vegetable Oil: a Risk Factor of Blood Lipid Disorder

Journal of Environmental Health and Sustainable Development, 2021
Introduction: Few pieces of evidence are available about the association between occupational exposure to vegetable oil and the risk of blood lipid problems. This study was aimed to investigate the relationship between exposure to vegetable oil and blood
