Fault Estimation and Fault Tolerant Control Strategies Applied to VTOL Aerial Vehicles With Soft and Aggressive Actuator Faults

IEEE Access, 2020
Actuator Fault Estimation (FE) and Fault Tolerant Control (FTC) strategies designed with model-based observers for Vertical Take-Off and Landing (VTOL) aerial vehicles are proposed and validated experimentally in this paper.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Reducing the Effects of Inaccurate Fault Estimation in Spacecraft Stabilization

Journal of Aerospace Technology and Management, 2017
Reference Governor is an important component of Active Fault Tolerant Control. One of the main reasons for using Reference Governor is to adjust/modify the reference trajectories to maintain the stability of the post-fault system, especially when a ...

Wasatch fault damage estimate

Eos, Transactions American Geophysical Union, 1979
Studies of ground motion caused in the Salt Lake City, Ogden, and Provo, Utah, areas by underground nuclear tests suggest that a moderate earthquake in the region could cause significant damage.Walter W. Hays, USGS seismologist, Golden, Colorado, said that the studies indicate that soils in some parts of the Utah urban corridor along the Wasatch fault ...

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
