We prove that the boundary measurement of the\nphoton currents allows unique and stable reconstructions of the absorption coefficient of the fluorophores at the excitation frequency and the quantum efficiency coefficient simultaneously\, provided\nthat some background medium parameters are known. Reconstruction algorithms are proposed and\nnumerically implemented as well.

We  introduce this idea to labeling of graphs. A (p\,q)-graph G=(V\,E) is said to be in Euclid(0) if there exists a bijection f: V(G) –> {1\,…\,p} such that for each induced C3 subgraph with vertices {v1\,v2\,v3} with f(v1)f(v3) . \nFor k > 1\, G is in Euclid(k) class of graphs if there exits smallest k such that G U Nk in Euclid(0)\, where Nk is the null graph with k isolated points. We exhibit infinitely many graphs in Euclid(k) for each k. The talk is target to general audiences. Several open problems will posed for future research. The report is the joint work with several high school\, undergraduate students and researchers.

In this talk we use biquandle brackets to enhance the biquandle counting matrix invariant of knotoids. This is joint work with Neslihan Gugumcu (Izmir Institute of Technology\, Izmir\, Turkey) and Natsumi Oyamaguchi (Shumei University\, Tokyo\, Japan).

Recent technological breakthroughs have enabled to gather data in previously unthinkable quantities at single cell level\, starting to suggest that cell fate decision is much more complex\, dynamic\, and stochastic than previously recognized. Multiscale interactions\, sometimes through cell-cell communications\, play a critical role in cell decision making. Dissecting cellular dynamics emerging from molecular and genomic scale in single-cell demands novel computational tools and multiscale models. In this talk\, I will present our recent works on analyzing single cell molecular data\, and their connections with cellular and spatial tissue dynamics. Our mathematical approaches bring together optimization\, statistical physics\, ODEs/PDEs\, and stochastic simulations along with machine learning techniques. By utilizing our newly developed computational tools along with their close integrations with new datasets collected from our experimental collaborators\, we are able to investigate several complex systems during development and regeneration to uncover new mechanisms in cell fate determination.
