A 3D‐Printed Model of Human Lactation

Advanced Healthcare Materials, EarlyView.
Breastfeeding supports infant and maternal health, yet in vitro models that mimic human lactation remain scarce. Here, light‐based 3D printing creates high‐resolution, alveoli‐inspired microwells that guide breast cells into polarized microtissues. The printed scaffolds embed slow‐release prolactin microcrystals to deliver hormonal cues, enabling human

Mathematical model of the LLC resonant converter

Proceedings of Tomsk State University of Control Systems and Radioelectronics, 2020
The numerical-analytical model of the voltage regulator based on full-bridge LLC resonant converter is proposed in this paper. In the text of the article LLC converters operation algorithm on each working interval is investigated. The proposed mathematical model describes key elements behavior on duty cycle and allows the study of nonlinear dynamic ...
