International Journal of Electrical Power & Energy SystemsDue to the wide application of modular multilevel converters (MMCs) in hybrid AC/DC distribution grids, enhancing the fault ride-through (FRT) capability of MMC is essential to improve the reliability of the hybrid AC/DC distribution grids. In this paper,

Successful Single‐Session Neural Self‐Regulation Through Neurofeedback Varies Between Features
Human Brain Mapping, Volume 47, Issue 11, 01 August 2026.We demonstrate that the ‘non‐learner’ problem is not a universal personal trait: using an intra‐subject cross‐over design, all participants successfully regulated multiple rhythms despite failing to modulate Theta. We identify distinct learning trajectories, highlighting the importance of frequency specificity in neural self‐regulation.

The Journal of Finance, Volume 81, Issue 4, Page 1841-1892, August 2026.ABSTRACT Republicans start more firms than Democrats. In a sample of 40 million party‐identified Americans between 2005 and 2017, we find that 5.5% of Republicans and 3.7% of Democrats become entrepreneurs. This partisan entrepreneurship gap is time‐varying—Republicans increase their relative entrepreneurship during Republican administrations and ...

Hunting and Hauora: Pig Hunters and Poaka in Aotearoa New Zealand
New Zealand Geographer, Volume 82, Issue 2, August 2026.ABSTRACT Though invasive, wild pigs (poaka) were fundamental to the survival of both Māori and Pākehā during colonisation, and they remain an essential source of kai (sustenance) today. Utilising a Whanganui case study, 24 participants, semi‐structured interviews, and thematic analysis guided by Kaupapa Māori principles, describe hunters' interests in ...
