Feed-forward Space Vector Modulation for Single-Phase Multilevel Cascade Converters with any DC voltage ratio [PDF]

open access: yes, 2009
Modulation techniques for multilevel converters can create distorted output voltages and currents if the DC link voltages are unbalanced. This situation can be avoided if the instantaneous DC voltage error is not taken into account in the modulation ...

GABAergic Neuron Activation in the RMTg‐VTA Pathway Modulates Dopaminergic Neuron Excitability and Social Stress Susceptibility in Male Mice

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 4, April 2026.
In susceptible mice, dopamine neurons in the VTA exhibit increased excitability along with upregulation of GABAA receptors. Administration of the GABAA receptor agonist muscimol reduces this neuronal hyperexcitability and reverses social avoidance behavior.

Molten Zinc Coordination Polymer Glass as a Host for Stable and Processable Optical Dye Composites

open access: yesEcoEnergy, Volume 4, Issue 2, April 2026.
Zinc‐based coordination polymer glass is employed to suppress aggregation‐caused quenching (ACQ) and enhance molecular stability, enabling improved luminescence performance in the solid state. The emission color of the hybrid composites can be tuned by varying the incorporated guest molecules, while the glass matrix effectively prevents aggregation and
