Seizure-onset mapping based on time-variant multivariate functional connectivity analysis of high-dimensional intracranial EEG : a Kalman filter approach [PDF]

open access: yes, 2016
The visual interpretation of intracranial EEG (iEEG) is the standard method used in complex epilepsy surgery cases to map the regions of seizure onset targeted for resection.

Assessment and Optimization of Hydrological Connectivity for Effective Management of Water Resources in the Samian Watershed [PDF]

open access: yesبرنامه ریزی فضایی
Water scarcity has become a critical issue in some regions. Accordingly, increasing attention has been given to the structural and functional connectivity of river networks as the primary source of surface water supply, while this can be a potential ...

Can meaningful effective connectivities be obtained between auditory cortical regions? [PDF]

open access: yes, 2001
Structural equation modelling (SEM) of neuroimaging data can be evaluated both for the goodness of fit of the model and for the strength of path coefficients (as an index of effective connectivity).

Connected bulk negative index photonic metamaterials [PDF]

open access: yesOptics Letters, 2009
We show the designs of bulk one- and two-dimensionally isotropic photonic negative index metamaterials working around telecom wavelengths. The designed structures are inherently connected, which makes fabrication by direct laser writing and chemical vapor deposition or other techniques possible.

Introduction Totally and Partial Connectivity Indices in Neutrosophic graphs with Application in Behavioral Sciences [PDF]

open access: yesNeutrosophic Sets and Systems, 2020
Connectivity is one of the most important concepts in graph theory. Since Neutrosophic Graphs are a branch of graphs, connectivity will be very important in this branch as well.

Evaluation of Pore-Type Carbonate Reservoir Connectivity Based on Electrical Imaging

open access: yesCejing jishu
Compared with conventional clastic rock reservoir, carbonate rock reservoir has less porosity and permeability relationship, because of its strong heterogeneity and complex pore structure.

Topological Evaluation of Four Para-Line Graphs Absolute Pentacene Graphs Using Topological Indices

open access: yesInternational Journal of Analysis and Applications, 2023
A real-number to molecular structure mapping is a topological index. It is a graph invariant method for describing physico-chemical properties of molecular structures specific substances. In that article, We examined pentacene’s chemical composition. The
