Tightly-coupled Fusion of Global Positional Measurements in Optimization-based Visual-Inertial Odometry [PDF]
IEEE/RSJ International Conference on Intelligent Robots and
Systems (IROS), Las Vegas, 2020, 2020 Motivated by the goal of achieving robust, drift-free pose estimation in long-term autonomous navigation, in this work we propose a methodology to fuse global positional information with visual and inertial measurements in a tightly-coupled nonlinear-optimization-based estimator.

Global asymptotic stability for Gurtin-MacCamy's population dynamics model [PDF]
arXiv, 2021 In this paper, we investigate the global asymptotic stability of an age-structured population dynamics model with a Ricker's type of birth function. This model is a hyperbolic partial differential equation with a nonlinear and nonlocal boundary condition. We prove a uniform persistence result for the semi-flow generated by this model.

Insertion of the FeB cofactor in cNORs lacking metal inserting chaperones
FEBS Letters, EarlyView.Nitric oxide reductase is an enzyme found in the bacterial denitrification pathway. The NOR active site contains a non‐heme iron, often, but not always inserted with the assistance of chaperones. Here, we study the insertion of FeB in the subfamily of cNORs lacking chaperones and found a putative channel, conserved in the family, perhaps enabling the ...

GLOBAL POSITIONING SYSTEM (GPS)
Pamukkale University Journal of Engineering Sciences, 1996 Use of GPS is becoming more widespread on surveying engineering. Especially, preference to GPS is increased by getting accuracy of order of milimeter, making observation on every weather forecast, without requiring intervisibility between station ...

FEBS Letters, EarlyView.LHCPs are transported to the thylakoid membrane via the (cp)SRP pathway. This process involves a transit complex of (cp)SRP43, (cp)SRP54 and LHCP, which interacts with (cp)FtsY and Alb3 at the membrane. GTP hydrolysis by (cp)SRP54 and (cp)FtsY triggers complex dissociation.
