Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

open access: yesMolecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Simulation study of FACTS devices based on AC-AC modular multilevel hexagonal chopper [PDF]

open access: yes, 2017
This paper proposes a new range of FACTS device based on direct AC-AC conversion, where the modular multilevel AC hexagonal chopper (M2AHC) is employed. The M2AHC is operated in quasitwo-level (Q2L) mode; and the heterodyne modulation is used to decouple

PMSG-Based Wind Energy Conversion Systems Integration Into DC Microgrids With a Novel Compact Converter

open access: yesIEEE Access, 2020
DC microgrids (DC-MGs) are recognized as an efficient alternative for common AC-MGs. DC-MGs need fewer power electronic converters since most of distributed generation (DG) units and electronic loads operate with DC voltage.
