LQR and SMC stabilization of a new unmanned aerial vehicle [PDF]

open access: yes, 2009
We present our ongoing work on the development of a new quadrotor aerial vehicle which has a tilt-wing mechanism. The vehicle is capable of take-off/landing in vertical flight mode (VTOL) and flying over long distances in horizontal flight mode.

Reduced Whole‐Brain Network Segregation and Dorsal Anterior‐Cingulate Cortex Neurochemical Alterations in Chronic Smokers

open access: yesBrain and Behavior, Volume 16, Issue 4, April 2026.
Chronic smokers exhibited less segregated brain networks and shifts in centrality from executive to reward‐related regions. Additional spectroscopy measures revealed lower tNAA in the dorsal anterior cingulate cortex, highlighting network‐level and neurochemical alterations that may underlie smoking‐related vulnerability.

Imprint of the Quasi‐Biennial Oscillation on the Ionosphere and Thermosphere

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract The Quasi‐Biennial Oscillation (QBO) is a dominant mode of stratospheric variability and is known to modulate the variability of the ionosphere‐thermosphere (IT) system. However, the extent of its influence on the ionosphere‐thermosphere system remains uncertain due to weak signals and confounding with similar periodicities in solar flux.
