Machine Learning‐Driven Multi‐Objective Optimization of Microchannel Reactors for CO₂ Conversion

open access: yesAdvanced Sustainable Systems, EarlyView.
This study introduces a novel method that combines CFD, RSM, and ML to improve a microreactor's performance utilizing the Sabatier reaction. A range of ML models is assessed, and the best one is selected to predict optimal reactor conditions. ML shows the ability to predict performance in just milliseconds, leading to a decrease in computational time ...

On the Relentless Pursuit of an Oral Insulin Delivery System: How Far is Too Far?

open access: yesAdvanced Therapeutics, EarlyView.
Injectable insulin preparations have far outpaced oral ones by virtue of adequate bioavailability and are driven by innovations, including insulin pumps, real‐time blood glucose monitoring, and artificial intelligence. In contrast, oral insulin delivery systems, including nanomedicines, continue to struggle and lag due to varied reasons.

Gauge Symmetry Breaking in a Throat Geometry [PDF]

open access: yes, 2008
We analyze behaviour of D3-branes in BGMPZ throat geometry. We show that although single brane has some of the moduli stabilized multi-brane system tends to expand and form a bound state. Such a system loses non-abelian gauge symmetry.
