  • Publication number: 20250148366
    Abstract: A method for training a machine learning system, including: based on at least one image dataset representing at least one portion of the hollow structure, calculating a signed distance field of each portion and calculating at least one geometrical parameter of each portion; generating a deployed in-use representation of the device by computing contact forces between the device and each portion based on the signed distance field and by applying these contact forces to a geometrical representation of the device; and training the machine learning system with each calculated geometrical parameter as an input and the corresponding deployed in-use representation as an associated target output, the obtained trained machine learning system being configured to receive as input at least one geometrical parameter and provide as output the deployed in-use representation of the device.

  • Patent number: 11884714
    Abstract: The invention described herein is based in part on the discovery of a protein/peptide crosslink, which introduces fluorescent properties, and which has been applied to synthesize analogues of melanocortin and amanitin as choice peptides to be explored in the context of isoindole peptides. Without limitation, it is expected that those trained in the art of peptide synthesis and stapling would appreciate the consequences of this invention such that other peptides of varied length can be similarly constrained by isoindole staples as featured herein.
