Super-resolution Fluorescence Microscopy

7.1K
Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been...

Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

    Area of Science:

    • Computer Vision
    • Machine Learning
    • Artificial Intelligence

    Background:

    • Few-shot segmentation (FSS) models struggle with generalization on complex query samples.
    • Existing FSS methods exhibit fragile performance when encountering hard query samples with seen-class objects.

    Purpose of the Study:

    • To propose a novel scheme, Base and Meta (BAM), to address the generalization bias in few-shot segmentation.
    • To improve the robustness and accuracy of FSS models when dealing with difficult query samples.

    Main Methods:

    • Introduced an auxiliary base learner alongside the conventional meta learner in the FSS framework.
    • Developed an adaptive integration strategy for coarse results from both learners.
    • Incorporated adjustment factors to estimate scene differences (style and appearance) between support and query image pairs.

    Main Results:

    • Achieved significant performance gains on standard benchmarks: PASCAL-5^i, COCO-20^i, and FSS-1000.
    • The proposed BAM scheme established new state-of-the-art results using simple base and meta learners.
    • Demonstrated the effectiveness of adaptive integration and scene difference estimation.

    Conclusions:

    • The Base and Meta (BAM) scheme effectively tackles the generalization bias in few-shot segmentation.
    • BAM offers a versatile and powerful approach, setting new performance benchmarks.
    • The study also explored practical extensions like generalized FSS and 3D point cloud FSS.
