Task‐Evoked Functional Activation and Coupling With CSF Flow Detected in the Human Brain With Ultrashort Echo Time fMRI at 7 T

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
Ultrashort and zero echo time (UTE and ZTE) MRI techniques generate functional contrast through inflow effects, making them suitable for studying cerebral blood flow and cerebrospinal fluid (CSF) dynamics. In a 7‐T study of 13 participants performing a visual task, we demonstrate that UTE produced robust, reproducible activations with group‐level ...

It's Daddy's Turn! Development of Turn‐Taking in Infant‐Father Interactions and Associations With Paternal Mentalizing and Involvement

Infancy, Volume 31, Issue 4, July/August 2026.
ABSTRACT Turn‐taking, the coordinated exchange of communicative signals between infants and caregivers, is vital for child communicative development. While it is considered a human universal, most research has focused on mother‐infant dyads. Given fathers' increasing caregiving involvement, understanding their contribution to early communication is ...

Groebner bases algorithm for optimal PMU placement

International Journal of Electrical Power & Energy Systems, 2020
Abstract In this paper a new method for solving optimal phasor measurement units (PMU) placement problem for full observability in power systems is proposed. A new algorithm is based on forming and solving Groebner bases set of equations for a defined optimization problem.
