Triangle Carrier-Based DPWM for Three-Level NPC Inverters [PDF]

open access: yesIEEE Journal of Emerging and Selected Topics in Power Electronics, 2018
This paper proposes a triangle carrier-based discontinuous pulsewidth modulation (TCB-DPWM) implement method for three-level neutral-point-clamped (3L-NPC) inverters. The function equivalent relationship of the proposed TCB-DPWM and space vector-based DPWM (SVB-DPWM) is mathematically analyzed in this paper.

Unveiling a New Link: Cholesterol Deficiency in Smith–Lemli–Opitz and Niemann–Pick C as a Driver of Ciliopathies

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 6, Page 1179-1191, June 2026.
ABSTRACT The ciliopathies are a group of genetic disorders caused by defective function of either the primary cilia (a large number) or the motile cilia (a much smaller number). These have been defined as diseases with mutations in genes encoding individual ciliary or cilia‐associated proteins.

The Lack of a COPII Cargo Receptor Erv14 Impacts Physiological Functions of the Vacuole in Saccharomyces cerevisiae

open access: yesTraffic, Volume 27, Issue 2, June 2026.
Loss of the cargo receptor Erv14 in Saccharomyces cerevisiae results in sensitivity to calcium, zinc, neutral extracellular pH, and elevated temperature. Furthermore, cells deleted in the ERV14 exhibits vacuolar fragmentation, enlarged lipid droplets, and metabolic alterations. Ruiz Salas, J. L. (2026) https://BioRender.com/b65g523. ABSTRACT Erv14 is a
