A Phase 2 Trial of Hydroxychloroquine in Individuals at Risk for Rheumatoid Arthritis

open access: yesArthritis &Rheumatology, Volume 78, Issue 4, Page 809-820, April 2026.
Objective Individuals with serum elevations of anti–cyclic citrullinated peptide (anti‐CCP) antibodies are at increased risk for future rheumatoid arthritis (RA). No pharmacologic interventions have been approved for the prevention of RA in such at‐risk individuals.

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

open access: yesIET Generation, Transmission & Distribution
ABSTRACT This paper presents a novel ferromagnetically shielded fault current limiter (FS‐FCL) configuration and control strategy for power systems. The proposed system introduces a controlled DC‐reactor design that effectively limits fault currents without significantly affecting the system voltage during normal operation.

Anticancer Potential of Piericidin A1 and Derivatives Isolated From Streptomyces sp. Associated With Palythoa variabilis From Brazilian Reefs

open access: yesChemistry &Biodiversity, Volume 23, Issue 4, April 2026.
A Streptomyces spp. strain, isolated from the zoantharian Palythoa variabilis, produces the complex I mitochondrial inhibitor piericidin A1 with effects on cancer cells proliferation and MTT‐formazan reduction at concentrations up to 0.1 aM. ABSTRACT Marine holobionts are an important source of bioactive natural products.

Cryptic Diversity and Genetic Variation in a Korean Endemic Freshwater Fish, the Korean Dark Chub (Zacco koreanus) Compared With Its Relative Zacco temminckii

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
The phylogenetic relationship analyses revealed four distinct lineages within Zacco koreanus, with the Nakdong and Seomjin River populations showing approximately 2.6% genetic divergence from other lineages—comparable to the interspecific distance between Z. koreanus and Z. temminckii (~2.7%).

A Dynamic Multi-Cell FCL to Improve the Fault Ride through Capability of DFIG-Based Wind Farms

open access: yesEnergies, 2020
Endowing wind farms (WFs) with fault ride through (FRT) capability is crucial to their continuous availability under various operating conditions. This paper proposes a dynamic adaptive multi-cell fault current limiter (MCFCL) topology to enhance the FRT

Mechanism and Control Analysis of Synchronous Frequency Resonance in Distributed Power Generation System Connected to Grid

open access: yesEnergy Science &Engineering, Volume 14, Issue 4, Page 2263-2276, April 2026.
Small‐signal modeling reveals that insufficient system damping positions conjugate poles near the imaginary axis, fundamentally explaining the SFR mechanism. A virtual resistance control is consequently proposed to damp the resonance and effectively suppress SFR, which is validated through Hardware‐in‐the‐Loop experiments.
