Journal of Biophotonics, EarlyView.Bright‐field images of unstained smears. (1) Sparse erythrocytes allow straightforward intensity‐ or phase‐based segmentation. (2) Overlapping cells blur boundaries, causing over‐ or under‐segmentation and lowering rule‐based accuracy, thus motivating overlap‐aware algorithms for reliable downstream feature extraction and classification.

Normalized Laplacian spectrum of some subdivision-joins and R-joins of two regular graphs
AKCE International Journal of Graphs and Combinatorics, 2018 In this paper we determine the full normalized Laplacian spectrum of the subdivision-vertex join, subdivision-edge join, R-vertex join, and R-edge join of two regular graphs in terms of the normalized Laplacian eigenvalues of the graphs.

A Nordhaus–Gaddum Problem for the Spectral Gap of a Graph
Journal of Graph Theory, EarlyView.ABSTRACT Let G $G$ be a graph on n $n$ vertices, with complement G¯ $\bar{G}$. The spectral gap of the transition probability matrix of a random walk on G $G$ is used to estimate how fast the random walk becomes stationary. We prove that the larger spectral gap of G $G$ and G¯ $\bar{G}$ is Ω(1∕n) ${\rm{\Omega }}(1\unicode{x02215}n)$.
