On the eigenvalues of general sum-connectivity Laplacian matrix
, 2013 The connectivity index was introduced by Randić (J. Am. Chem. Soc. 97(23):6609-6615, 1975) and was generalized by Bollobás and Erdös (Ars Comb. 50:225-233, 1998).

Topological Study of Zeolite Socony Mobil-5 via Degree-Based Topological Indices
Journal of Chemistry, 2021 Graph theory is a subdivision of discrete mathematics. In graph theory, a graph is made up of vertices connected through edges. Topological indices are numerical parameters or descriptors of graph.

Representation of landscape hydrological connectivity using a topographically driven surface flow index. [PDF]
, 2009 This paper assesses the extent to which a topographically defined description of the spatial arrangement of catchment wetness can be used to represent landscape hydrological connectivity in temperate river catchments.

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3
Molecular Oncology, EarlyView.PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

Intra-session test-retest reliability of functional connectivity in infants
NeuroImage, 2021 Resting functional MRI studies of the infant brain are increasingly becoming an important tool in developmental neuroscience. Whereas the test-retest reliability of functional connectivity (FC) measures derived from resting fMRI data have been ...

FEBS Open Bio, EarlyView.Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...
