Implicit motor adaptation patterns in a redundant motor task manipulating a stick with both hands

eLife
The remarkable ability of the motor system to adapt to novel environments has traditionally been investigated using kinematically non-redundant tasks, such as planar reaching movements.

Analytical Study on Mission Control Element System Availability for Korea Multipurpose Satellite (KOMPSAT) I [PDF]

Journal of Astronomy and Space Sciences, 1998
To estimate the availability of the MCE for KOMPSAT I, mathematical models of H/W and S/W availability, the availability estimating methods for parallel and redundant system were presented. Furthermore, to improve and estimate the MCE system availability,

Fail-safe system for activity cooled supersonic and hypersonic aircraft [PDF]

A fail-safe-system concept was studied as an alternative to a redundant active cooling system for supersonic and hypersonic aircraft which use the heat sink of liquid-hydrogen fuel for cooling the aircraft structure.

Identifying transcription factors controlling the basal expression of human MRP4 highlights a substantial role for Sp1

FEBS Open Bio, EarlyView.
The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.

Reliable dual-redundant sensor failure detection and identification for the NASA F-8 DFBW aircraft [PDF]

A technique was developed which provides reliable failure detection and identification (FDI) for a dual redundant subset of the flight control sensors onboard the NASA F-8 digital fly by wire (DFBW) aircraft.

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

FEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Lifetime Distribution for a Mixed Redundant System with Imperfect Switch and Components Having Phase–Type Time-to-Failure Distribution

Mathematics
Recently, a mixed redundancy was introduced among the redundant design strategies to achieve a more reliable system within the equivalent resources.

Classes of Byzantine Fault-Tolerant Algorithms for Dependable Distributed Systems. [PDF]

, 1998
This thesis concentrates on the design of new algorithms for fault-tolerant systems based on system-level hardware masking redundancy. It is argued that any system in which a reliability improvement of at least a factor 100 is required should be based on
