Optimized Space-Vector Modulation to Reduce Neutral Point Current for Extending Capacitor Lifetime in Three-Level Inverters

IEEE Access, 2020
In this paper, an optimized space-vector modulation (SVM) to reduce DC-link ripple current in three-level inverters is presented. Various types of capacitors can be utilized to balance the voltage in the DC-link of voltage source inverters.

Hierarchical Summary Statistics Encoding Across Primary Visual and Posterior Parietal Cortices

Advanced Science, EarlyView.
This study shows that mouse V1 simultaneously encodes the ensemble mean and variance of motion, providing a robust summary‐statistic representation that persists despite single‐neuron variability. These signals propagate to PPC, where they are transformed into abstract category representations during decision making.

Mitochondrial CircRNA CircMT‐RNR2 Safeguards Antioxidant Defense to Support Fibroblast Functions in Wound Repair

Advanced Science, EarlyView.
CircMT‐RNR2 promotes wound healing by enhancing fibroblast proliferation, migration, contraction, and extracellular matrix (ECM) production. It sustains mitochondrial redox balance by stabilizing the antioxidant protein PRDX3, thereby reducing ROS‐induced damage. In diabetic foot ulcers, hypoxia, hyperglycemia, and reduced FGF2 and EGF expression lower
