[02667] Coupled Active Contour Segmentation of Clue Cells from Immunofluorescence Microscopy

  • Session Time & Room : 5C (Aug.25, 13:20-15:00) @D515
  • Type : Contributed Talk
  • Abstract : Presence of clue cells is a critical criterion for diagnosis of bacterial vaginosis. We propose a coupled active contour model for segmenting the clue cells from immunofluorescence microscope images of the samples. It enables jointly segmenting the boundaries of the epithelial cell, its nucleus, and distinct bacteria. Convexification is formulated on top of the levelset framework using characteristic functions. Our approach provides a global optimal solution. Efficacy of the method is demonstrated on clinical data.

[01762] Generalized proofs of positivity of the solutions to population models

  • Session Time & Room : 5C (Aug.25, 13:20-15:00) @D515
  • Type : Contributed Talk
  • Abstract : Dynamic models of many processes in the biological and physical sciences are governed by systems of ordinary differential equations called compartmental systems. Since the dependent variables in such models denote population size, the solutions that start from positive initial conditions remain positive for all time. In this study, two generalized proofs of positivity of the solutions to compartmental models are presented. These compartmental models can be used in many applications including epidemiology and population dynamics.

[00667] Effect of tumor-associated neutrophils on tumor growth : A mathematical model

  • Session Time & Room : 5C (Aug.25, 13:20-15:00) @D515
  • Type : Contributed Talk
  • Abstract : Tumor-associated neutrophils (TANs) have been under discussion for their dual role on tumor microenvironment, but they are emerging as important agents in tumor invasion. In this study, we divided TANs into two different phenotypes: N1 TANs, the anti-tumor neutrophils and N2 TANs, the tumorigenic neutrophils. We developed a mathematical model to investigate the dynamics of tumor growth between different TANs and responses to various stimuli, and finally to build simulations for brain tumor treatment.
