Dynamic Event‐Triggered Robust Model Predictive Control for Quadrotor Trajectory Tracking

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 36, Issue 6, Page 3676-3688, April 2026.
ABSTRACT This paper addresses the trajectory tracking problem for a full‐state quadrotor subject to physical model constraints and unknown external disturbances. A robust tube‐based model predictive control (MPC) approach is successfully applied to the system, which is subject to bounded disturbances and hard constraints.

Three‐Dimensional Lightning Characteristics of Severe Convective Weather in Shanghai

open access: yesMeteorological Applications, Volume 33, Issue 2, March/April 2026.
Using 2022–2024 ADTD data, this study analyzes 3D lightning in Shanghai's severe convection. Activity peaks in August and afternoon hours, varies by weather type, and concentrates spatially in Pudong and Chongming. Results provide key references for selecting lightning indicators in forecasting and warning systems. ABSTRACT Using ADTD three‐dimensional

Coevolution of phyllosilicate, carbon, sulfide, and apatite in Ryugu's parent body

open access: yesMeteoritics &Planetary Science, Volume 59, Issue 8, Page 2073-2096, August 2024.
Abstract We analyzed an asteroid Ryugu sample returned to Earth by JAXA's Hayabusa2 mission using nanoIR, SEM, and TEM microscopy. We identified multiple distinct carbon reservoirs within the phyllosilicate matrix and demonstrate infrared spectral affinities for some of the carbon to insoluble organic matter (IOM).

Surface‐Guided Crystallization of Xanthine Derivatives for Optical Metamaterial Applications

open access: yesAdvanced Materials, Volume 36, Issue 8, February 22, 2024.
Millimeter sized extremely birefringent thin crystalline sheets formed from the small organic molecules theophylline and etophylline with controlled orientation are grown from solution via epitaxy with a quartz substrate. The films are then used to fabricate flat polarization‐dependent optical metamaterials.

Corrected event dataset of FY-4A LMI, 2019–2023

open access: yes
Abstract. The Lightning Mapping Imager (LMI) aboard the Fengyun-4A (FY-4A) satellite, once one of the only two geostationary lightning detection payloads operating in space, has accumulated a substantial volume of observational data. Extensive efforts have been made to correct lightning geolocation deviations, including payload misalignment correction,
