Molecular Models

Physical models representing molecular architectures of chemical compounds play essential roles in understanding chemistry. The use of molecular models makes it easier to visualize the structures and shapes of atoms and molecules.

¹H NMR Signal Multiplicity: Splitting Patterns

When protons A and X are coupled, their nuclear spin energy levels are slightly modified. This is because the energy required to excite proton A to a spin state parallel to proton X is slightly different from the energy required for it to become anti-parallel to spin X. Consequently, there are two possible excitation frequencies for A (A1 and A2), depending on the spin state of X, and vice versa. The mutual nature of coupling implies that the difference between frequencies A1 and A2, indicated...

  • To address the limitations of general VFMs in fine-grained semantic segmentation.

Main Methods:

  • Developed a full-stack approach integrating molecular empowered learning, SAM adapter, and molecular oriented corrective learning.
  • Enabled annotation-engaging lay annotators to reduce pixel-level annotation needs.
  • Adapted SAM for specific semantics and refined segmentation accuracy.

Main Results:

  • The all-in-SAM model significantly improved cell classification performance on diverse datasets.
  • Demonstrated robust performance even with varying annotation quality.
  • Validated through experiments on both in-house and public datasets.

Conclusions:

  • The molecular empowered all-in-SAM model reduces annotator workload and enhances pathology image analysis.
