A trust‐region funnel algorithm for gray‐box optimization

AIChE Journal, EarlyView.
Abstract Gray‐box optimization, where parts of optimization problems are represented by algebraic models while others are treated as black‐box models lacking analytic derivatives, remains a challenge. Trust‐region (TR) methods provide a robust framework for gray‐box problems through local reduced models (RMs) for black‐box components, but they are ...

An ultra‐processed food‐based cafeteria diet induces obesity, metabolic dysfunction, and tissue‐specific gene dysregulation in C57BL/6 mice

Animal Models and Experimental Medicine, EarlyView.
This schematic figure illustrates the experimental design and key findings of the study. Forty male C57BL/6 mice were assigned to either a standard diet control group or a cafeteria diet (CAFD) group for 16 weeks. CAFD induces obesity, insulin resistance (HOMA‐IR), hepatic steatosis, and dysregulation of a number of genes in visceral and subcutaneous ...
