Superconductivity in Hourglass Dirac Chain Metals (Ti, Hf)IrGe
Advanced Science, Volume 12, Issue 43, November 20, 2025.We report the discovery of ternary germanide superconductors MIrGe (M = Ti, Hf) that host hourglass Dirac chains protected by nonsymmorphic symmetry. These compounds exhibit bulk type‐II superconductivity with fully gapped states and preserved time‐reversal symmetry, as confirmed by µSR measurements.

An approved frequency tracking method in connected element interferometry
MATEC Web of Conferences, 2017 Carrier tracking loop is a basic method of frequency tracking in CEI (connected element interferometry), but the tracking error is very large or even worse at high dynamic.

Regulation of parallel converters based AC microgrid considering non‐ideal grid conditions
Energy Conversion and Economics, Volume 6, Issue 1, Page 1-12, February 2025.Abstract This study proposes an alternating current microgrid that integrates renewable energy sources to enhance energy sustainability. In this system, wind and solar power are initially converted to DC using DC–DC converters; subsequently, they are integrated into a common AC bus through parallel voltage source converters.
