An electro–magnetic–porous multigradient nanofibrous electromagnetic interference (EMI) membrane is fabricated via shear‐induced in situ fibrillation and layer‐by‐layer assembly. Leveraging a multigradient‐induced “impedance matching–polarization–reabsorption” synergistic mechanism, the membrane achieves absorption‐dominated high‐efficiency EMI ...

Predicting Performance of Hall Effect Ion Source Using Machine Learning
This study introduces HallNN, a machine learning tool for predicting Hall effect ion source performance using a neural network ensemble trained on data generated from numerical simulations. HallNN provides faster and more accurate predictions than numerical methods and traditional scaling laws, making it valuable for designing and optimizing Hall ...

Abstract Manned space exploration to distant destinations, including Mars, continues to be an aspiration of humankind. Space travel does, however, present many challenges to the body, amongst which adaptation to microgravity is perhaps the largest. For instance, both short and long manned spaceflight missions have shown substantial deleterious effects ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Abstract Field‐aligned currents (FACs) are the main physical mechanism behind magnetosphere–ionosphere coupling, with these currents communicating environmental changes between the two regions of geospace. Field‐aligned currents are thus a key factor in monitoring space weather, both from an operational and scientific perspective.

Grid Fragility, Blackouts, and Control Co‐Design Solutions
Hierarchical grid control and GRADIENTS categories. ABSTRACT The grid is undergoing a large‐scale transformation, including a significant reduction of synchronous generators, a high penetration of inverter‐based resources and renewables, substantial demand growth, new extra‐large loads, aging infrastructure and a concerning vulnerability to ...
