DOI: 10.1007/s10773-017-3529-x

Abstract: We present a necessary and sufficient product criterion for bipartite quantum states based on the rank of realignment matrix of density matrix. Then, this approach is generalized to multipartite systems. We first introduce the concept… read more here.

DOI: 10.1007/s11229-017-1481-1

Abstract: Paul Hoyningen-Huene argues that what makes scientific knowledge special is its systematic character, and that this can be used to solve the demarcation problem. He labels this STDC: “Systematicity Theory’s Demarcation Criterion.” This paper argues… read more here.

Abstract: SUMMARY Unlike the adult mammalian retina, Müller glia (MG) in the adult zebrafish retina are able to dedifferentiate into a ‘‘stem cell’’-like state and give rise to multipotent progenitor cells upon retinal damage. We show… read more here.
