Metallicities of Young Open Clusters I: NGC 7160 and NGC 2232

, 2010
We present a moderate-resolution spectroscopic analysis of the 10-25 Myr clusters NGC 7160 and NGC 2232, using observations obtained with the WIYN 3.5-m telescope. Both NGC 7160 and NGC 2232 are found to have super-solar metallicities, with a mean [Fe/H]

Caenogastropods and heterobranch gastropods from the Hettangian deposits of Luxembourg: palaeobiogeography and Early Jurassic faunal recovery in the western Tethys

Papers in Palaeontology, Volume 12, Issue 1, January/February 2026.
Abstract We describe the Hettangian Caenogastropoda and Heterobranchia of the Luxembourg Sandstone Formation, a wedge of clastic sediments deposited along the eastern margin of Paris Basin during the Early Jurassic. Five new genera and 11 new species are erected: Bourguetia bipartita sp. nov., Globularia delsatei sp. nov., Oonia feidtorum sp.

Ferromagnetically Shielded Fault Current Limiter (FS‐FCL) Evaluation in Power Line

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study introduces a new ferromagnetically shielded FS‐FCL design and its control strategy for limiting and interrupting fault currents. The fully shielded core structure enhances inductance and prevents saturation, enabling an immediate fault response without causing voltage drop during normal conditions.

Stability and Synchronization of MMC‐HVDC Systems Using SRF and Inertia‐Based PLLs

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study investigates the influence of synchronous reference frame PLL (SRF‐PLL) and the inertia PLL (IPLL) on the stability of grid‐connected modular multilevel converter high voltage direct current (MMC‐HVDC) systems. The findings highlight intrinsic stability limitations of PLL‐based systems, offering insights toward more stable, PLL‐less ...
