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

open access: yesPapers 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

open access: yesIET 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.

Analysis of a Three Phase Induction Motor Directly from Maxwell's Equations

open access: yes, 2011
The torque developed in a three phase AC squirrel cage motor is usually expressed in terms of resistances and reactances of the stator, the rotor, and the motor as a whole. We use Maxwell's equations to find the torque in terms of geometrical parameters.

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

open access: yesIET 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 ...

Total Distortion—A New Power Quality Index on Current Harmonic Evaluation for Users With Internal Loads and DERs

open access: yesIET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
ABSTRACT The IEEE Std 519–2022 IEEE Standard for harmonic control in electric power systems is widely used for controlling the harmonics in the electric power system. It uses the total demand distortion (TDD) for current harmonic evaluation at the point of common coupling (PCC).
