Topological design and control of buck-boost multilevel inverters [PDF]
, 2019 Most dc-ac inverters developed to date can support only voltage buck energy conversion, and are therefore not suitable for use as interfacing inverters for tapping energy from renewable sources or other alternative clean sources like fuel cells, where an unrestrained voltage variation range is unavoidable.

Ecology and Evolution, Volume 16, Issue 7, July 2026.This study reports the first complete mitogenome of the estuarine clam Potamocorbula amurensis, revealing its phylogenetic position as a sister group to the Myidae–Dreissenidae clade. Molecular dating indicates a Middle Jurassic divergence, and positive selection was detected in the nad5 gene, suggesting mitochondrial adaptations to osmotic stress in ...

Mass spectrometry imaging of N‐linked glycans: Fundamentals and recent advances
Mass Spectrometry Reviews, Volume 45, Issue 4, Page 599-623, July/August 2026.Abstract With implications in several medical conditions, N‐linked glycosylation is one of the most important posttranslation modifications present in all living organisms. Due to their nontemplate synthesis, glycan structures are extraordinarily complex and require multiple analytical techniques for complete structural elucidation.

Design of mine-used power supply with super wide input voltage range
Gong-kuang zidonghua, 2016 For problems of existing mine-used flameproof and intrinsically safe type power supply with multiple input voltage level such as large voltage fluctuation, heavy weight and difficult maintenance, a design scheme of mine-used power supply with super wide ...

Space Weather, Volume 24, Issue 7, July 2026.Abstract Geomagnetically Induced Currents (GICs) are a key space weather hazard to ground‐based infrastructure, and can cause mis‐operation or even equipment failure. The solar wind interacts with the Earth's geomagnetic field, causing the magnetic field at ground level to vary with time.

Molecular Ecology, Volume 35, Issue 13, July 2026.ABSTRACT Crop wild relatives are a valuable source of genetic material for improving cultivated crops. However, feral populations—self‐sustaining plants that have escaped cultivation—are often mistaken for wild relatives because they exhibit traits such as seed dispersal and dormancy, which resemble wild forms and support persistence in natural ...

Comparative Analysis of Fourth-Order Non-Isolated DC-DC Converters: Ćuk, SEPIC and Zeta [PDF]
Journal of Electrical and Electronics EngineeringThis paper presents a comparative study of three fourth-order non-isolated DC-DC converters: Ćuk, SEPIC, and Zeta. Analytical expressions for output voltage ripple were derived for each topology, and their accuracy was validated through numerical ...
