Estimating Atmospheric Turbulence Intensity From Cup Anemometer Data

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Conventional cup anemometers are widely used but limited by coarse sampling in representing turbulence. To address this, we introduce a cumulative spectral density (CSD) approach that quantifies turbulence contributions from 1‐min wind speed records while explicitly accounting for aliasing.

One‐Step Core‐Shell Structuring of Silicon Graphene Composite Anode Materials by Aqueous Reduced Graphene Oxide: Toward Practical Use of High‐Performance Lithium‐Ion Battery

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 1, January 2026.
The one‐step QrGO‐coating strategy ensures uniform encapsulation within an adhesive and conductive layer, addressing SiOx anode challenges. It mitigates cracking, enhances charge transport, and supports a high silicon content of 20 wt.%, surpassing commercial 5 wt.%. QrGO‐coated electrodes achieve superior capacity retention, with full cells delivering

Mobility Management for the Low‐Altitude Economy: Latency‐Aware Handover Design

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper develops a latency‐aware mobility‐management framework for aerial vehicles operating in hybrid terrestrial non‐terrestrial networks. We formulate a MILP for optimal AV AP association and propose a greedy handover policy using predicted coverage, rate and handover latency.
