D-branes on AdS flux compactifications [PDF]

, 2007
We study D-branes in N=1 flux compactifications to AdS_4. We derive their supersymmetry conditions and express them in terms of background generalized calibrations.

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.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Accurate Tracking of Aggressive Quadrotor Trajectories using Incremental Nonlinear Dynamic Inversion and Differential Flatness

, 2020
Autonomous unmanned aerial vehicles (UAVs) that can execute aggressive (i.e., high-speed and high-acceleration) maneuvers have attracted significant attention in the past few years.

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.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Improved dynamic performance of triple active bridge DC-DC converter using differential flatness control for more electric aircraft applications

Results in Engineering
The triple active bridge (TAB) converter has been proposed to improve power density and availability in more electric aircraft applications. However, the conventional proportional-integral (PI) controller used for TAB voltage control often exhibits slow ...

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.
