The special cuts of the 600-cell [PDF]
Beiträge zur Algebra und Geometrie, 2008 A polytope is called regular-faced if each of its facets is a regular polytope. The 4-dimensional regular-faced polytopes were determined by G. Blind and R. Blind. Regarding this classification, the class of such polytopes not completely known is the one which consists of polytopes obtained by removing some set of non-adjacent vertices (an independent ...

Cuts and flows of cell complexes [PDF]
Journal of Algebraic Combinatorics, 2013 We study the vector spaces and integer lattices of cuts and flows of an arbitrary finite CW complex, and their relationships to its critical group and related invariants. Our results extend the theory of cuts and flows in graphs, in particular the work of Bacher, de la Harpe and Nagnibeda.

The candidate multi-cut for cell segmentation [PDF]
2018 IEEE 15th International Symposium on Biomedical Imaging (ISBI 2018), 2018 Two successful approaches for the segmentation of biomedical images are (1) the selection of segment candidates from a merge-tree, and (2) the clustering of small superpixels by solving a Multi-Cut problem. In this paper, we introduce a model that unifies both approaches.

Cutting through the complexity of cell collectives [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2013 Via strength in numbers, groups of cells can influence their environments in ways that individual cells cannot. Large-scale structural patterns and collective functions underpinning virulence, tumour growth and bacterial biofilm formation are emergent properties of coupled physical and biological processes within cell groups.

Microtubules cut loose at the cell cortex [PDF]
Fly, 2012 The ability of the microtubule cytoskeleton to rapidly and locally reorganize itself in response to intra- and extracellular signals is essential to its wide range of functions. A site of tightly regulated microtubule dynamics--and the major interface between the microtubule cytoskeleton and the extracellular environment--is the cell cortex, where the ...

Cell Segmentation with Random Ferns and Graph-cuts [PDF]
2016 IEEE International Conference on Image Processing (ICIP), 2016 ABSTRACT The progress in imaging techniques have allowed the study of various aspect of cellular mechanisms. To isolate individual cells in live imaging data, we introduce an elegant image segmentation framework that effectively extracts cell boundaries, even in the presence of poor edge details. Our approach works in two stages. First,

Consistency analysis of PD-L1 immunohistochemistry antibodies in esophageal squamous cell carcinoma [PDF]
Zhongguo aizheng zazhi, 2023 Background and purpose: Immunohistochemistry (IHC) expression of programmed death ligand-1 (PD-L1) is the most widely used biomarker for predicting the efficacy of esophageal cancer immunotherapy, and accurate and reliable PD-L1 testing is crucial for ...

ADAPTIVE PARAMETER SELECTION FOR GRAPH CUT-BASED SEGMENTATION ON CELL IMAGES
Image Analysis and Stereology, 2016 Graph cut segmentation approach provides a platform for segmenting images in a globally optimised fashion. The graph cut energy function includes a parameter that adjusts its data term and smoothness term relative to each other.
