Dynamic Cell Division for Interference Management in Satellite Direct‐to‐Cell Systems

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Direct‐to‐cell (D2C) connectivity enables future non‐terrestrial networks to provide service directly to standard terrestrial user equipment (UE) when terrestrial networks (TN) are unavailable. In this work, the satellite system is considered as a secondary network that supplements existing TN coverage while minimizing interference to the ...

Polarity‐Engineered, Tribo‐Positive Imidazolium‐Mediated Crosslinked 6FDA‐Durene Films for Triboelectric Nanogenerator

Small, EarlyView.
Imidazolium‐mediated crosslinking transforms 6FDA‐durene PI from tribo‐negative to tribo‐positive by modulating the surface electronic structure and charge‐transfer behavior. DFT calculations confirm the experimentally observed polarity transition.

Do Product Market Reforms Work? Assessing Regulatory Changes Impacting Competition

Southern Economic Journal, EarlyView.
ABSTRACT We create a new dataset that characterizes studies of product market reforms implemented from 1932 to 2011. We examine the size and origins of differences in estimated impacts based on an OECD classification scheme for potentially competitive restrictions of regulation. The median impact from switching to a pro‐competitive environment is a 19%

Bath Vibration During Open Eye Formation in a Physical Model of a Steelmaking Ladle

steel research international, EarlyView.
Using a physical model, this study shows that vibration measurements reliably predict open eye size in steelmaking ladles, offering a practical alternative to visual monitoring. Vessel vibrations stabilize faster than the open eye, except at high frequencies near the bottom.

Preliminary Study on Unit Commitment for Renewable Energy Integration Considering Operation Cost and Life Cycle Assessment

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
Most countries, including Japan, are focused on achieving net‐zero greenhouse gas (GHG) emissions by 2050, which requires quick action. Despite the increasing level of renewable power generation in power grids, fossil fuel power plants still have a significant role in producing GHG emissions, causing serious environmental issues.
