Slowly Rotating Traversable Wormholes Supported by Radially Varying String‐Fluid Matter: From Regular Geometries to Photon Trajectories

open access: yesAnnalen der Physik, Volume 538, Issue 6, June 2026.
This study examines slowly rotating traversable wormholes supported by string fluids whose properties change with radius. The matter smoothly shifts from a de Sitter‐like core to a string‐dominated exterior, producing a regular, horizon‐free spacetime.

Changes in the Westward Transport of Saharan Dust From West Africa With Anthropogenic Forcing in the WRF Model

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Large uncertainties exist for future westward Saharan dust transport with increasing Greenhouse Gas emissions. We evaluate future changes in westward dust transport at the longitude of 18.6°W and a latitude range of 4°N–30°N using the Weather Research and Forecasting Model (WRF) with the GOCART dust module for the present‐day, with ERA‐Interim

Modified golden section search based MPPT algorithm for the WECS

open access: yes, 2021
The maximum power point tracking (MPPT) algorithms aim to provide maximum power for each time even though the environmental condition changes. It is so important to get maximum available power at each time from the wind energy conversion system (WECS) to

Advanced Functional Materials for Marine Energy Utilization

open access: yesInterdisciplinary Materials, Volume 5, Issue 3, Page 317-356, May 2026.
Marine renewable energy is an important future clean energy supply. We construct and sort out the material system for marine energy capture and conversion, transmission, storage, and utilization for the first time. ABSTRACT Several features of marine energy, including large reserves, sustainable utilization, environmental friendliness, make it a ...
