A Note on Degenerate and Spectrally Degenerate Graphs [PDF]

open access: yesJournal of Graph Theory, 2012
AbstractA graph G is called spectrally d‐degenerate if the largest eigenvalue of each subgraph of it with maximum degree D is at most . We prove that for every constant M there is a graph with minimum degree M, which is spectrally 50‐degenerate. This settles a problem of Dvořák and Mohar (Spectrally degenerate graphs: Hereditary case, arXiv: 1010.3367).

Spontaneous immunomodulation and regulation of angiogenesis and osteogenesis by Sr/Cu-borosilicate glass (BSG) bone cement to repair critical bone defects

open access: yesBioactive Materials, 2023
Injectable bone biomaterials like bone cement should be designed and fabricated with certain biological criteria, which include: 1) recruitment and polarization of the macrophages from M1 (pro-inflammatory) to M2 (anti-inflammatory) phenotype, 2) enhance
