Recovering steady‐state visual evoked potential‐related electroencephalography during amplitude‐modulated‐transcranial alternating current stimulation using dynamic adaptive stimulation artifact source separation

open access: yesJournal of Intelligent Medicine, EarlyView.
Abstract Simultaneous electroencephalography (EEG) recording during transcranial alternating current stimulation (tACS) is strongly contaminated by stimulation artifacts, limiting direct assessment of neural activity. Steady‐state visual evoked potentials (SSVEPs) provide frequency‐specific and phase‐locked responses, making them suitable for ...

Mapping Multi‐Stakeholder Engagement: A Q Methodology in a Regional Project Management Scenario

open access: yesStrategic Change, EarlyView.
ABSTRACT Research on project management describes the essence of projects involving multiple stakeholders, stressing the value derived from diverse work practices. However, this underestimates issues of counterproductive disagreements associated with diverse groups participating in a project.

Health risk assessment of heavy metal accumulation in fruits exposed to geothermal waters: a case study and global implications

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The present study investigated the potential health risks of heavy metals (HMs) in the fruits and leaves of mulberry and sour cherry trees exposed to water from Sivas geothermal basin (Turkey). RESULTS The target HMs were ranked according to their hazard index as: Cd < Pb < Zn < Cu < Ni < Mn < Cr. The total hazard index for mulberry

A Complex‐Frequency Framework for Kerker Unidirectionality in Photonic Resonators

open access: yesLaser &Photonics Reviews, EarlyView.
ABSTRACT Electromagnetic scattering exhibits various anomalous behaviors, such as forward or backward scattering effects known as the Kerker conditions. These anomalies appear in non‐Hermitian photonic resonators and are mathematically described by operators with complex eigenfrequencies.
