AbstractAntimicrobial lipopeptides (AMLPs) represent a promising solution to global antibiotic crisis, yet their precision design remains challenging due to the inability of current computational models to account for N-terminal fatty acid modification. Here we develop a deep learning-driven AMLP model for de novo design of AMLPs by integrating a chain-as-prompt mechanism with domain-adaptive transfer learning, effectively bridging the representation gap between peptide sequence and lipid-induced bioactivity. Using the AMLP model, 2657 evolutionarily selected RiPP-derived core peptide sequences from 96,911 bacterial genomes are inspiringly designed for virtual lipidation with seven N-terminal fatty acid chains (C6–C18) followed by predictive screening, generating 6197 candidate sequences.

This version is subject to further edits and will be replaced automatically by the final Version of Record. All legal disclaimers apply. AbstractSewing is one of the established methods used to fabricate and assemble multilayer insulation (MLI) blankets for aerospace applications, yet the resulting effective flexural behavior remains insufficiently understood. This study investigates the room-temperature, quasi-static flexural behavior of MLI blankets composed of aluminized BoPET radiation shields and polyester net spacers across structural configurations of 2, 6, 12, and 24 layers. A full factorial design was employed to evaluate the influence of the number of layers, stitch density, needle thread tension, and needle foot force. Statistical analyses demonstrated that the number of layers is the dominant factor governing flexural response. Among the sewing parameters, needle thread tension was associated with modifications in bending length, while needle foot force primarily affected local compaction.
