Real-Time Trajectory Planning and Control for Constrained UAV Based on Differential Flatness
International Journal of Aerospace Engineering, 2022 The trajectory planning of UAV with nonholonomic constraints is usually taken as differential algebraic equation to solve the optimal control problem of functional extremum under the condition of inequality constraints.

The Hitchin-Witten Connection and Complex Quantum Chern-Simons Theory [PDF]
, 2014 We give a direct calculation of the curvature of the Hitchin connection, in geometric quantization on a symplectic manifold, using only differential geometric techniques.

Real-time trajectory generation for differentially flat systems [PDF]
International Journal of Robust and Nonlinear Control, 1996 Two algorithms for real-time trajectory generation for differentially flat systems with unstable zero dynamics are described. One is based on a receding horizon point to point steering, the other allows additional minimization of a cost function. The two-degree-of-freedom approach is used: real-time trajectory generation followed by local stabilization.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

In-domain control of a heat equation: an approach combining zero-dynamics inverse and differential flatness [PDF]
, 2015 This paper addresses the set-point control problem of a heat equation with in-domain actuation. The proposed scheme is based on the framework of zero dynamics inverse combined with flat system control.

FEBS Letters, EarlyView.Multidrug transporters BpeB and BpeF from the Gram‐negative pathogen Burkholderia pseudomallei have a hydrophilic patch in their substrate‐binding pocket. Drug susceptibility tests and growth curve analyses using an Escherichia coli recombinant expression system revealed that the hydrophilic patches of BpeB and BpeF are involved in the substrate ...

Brane-World Cosmology, Bulk Scalars and Perturbations [PDF]
, 2001 We investigate aspects of cosmology in brane world theories with a bulk scalar field. We concentrate on a recent model motivated from supergravity in singular spaces.
