Active control of intracellular pH
Respiration Physiology, 1978When the interior of a squid giant axon is loaded with acid, the cell responds by extruding that acid in an energy-requiring process. Our results indicate that this acid extrusion is accomplished by exchanging external HCO3- for internal Cl- at the expense of ATP.

Active Spacecraft Potential Control
Space Science Reviews, 1997Charging of the outer surface or of the entire structure of a spacecraft in orbit can have a severe impact on the scientific output of the instruments. Typical floating potentials for magnetospheric satellites (from +1 to several tens of volts in sunlight) make it practically impossible to measure the cold (several eV) component of the ambient plasma ...

Algorithms for Active Noise Control
2009The previous regulations about acoustics in buildings ruled only isolation, forgetting other important subjects. The new code in Spain, specifically the DB-HR document, also include the regulations of excessive noise reverberating that produces and causes discomfort in many cases non-speech intelligibility, this circumstance is crucial in certain areas.

Talin controls integrin activation
Biochemical Society Transactions, 2004Tight, dynamic control of the affinity of integrin adhesion receptors for their extracellular ligands (integrin activation) is essential for the development and functioning of multicellular organisms. Integrin activation is controlled by intracellular signals that, through their action on integrin cytoplasmic domains, induce conformational changes in ...

Experience with active congestion control
Proceedings DARPA Active Networks Conference and Exposition, 2003Active congestion control (ACC) applies active networking to feedback congestion control in a high bandwidth-delay product network, shortening the feedback loop by filtering traffic in the network near congestion. This paper describes recent simulation results showing the function of the system in TCP networks across a range of bandwidth-delay products.

Control and Coordination of Economic Activity
1987The particular point of view of the present paper is that it looks upon the economy as a control system. This approach was pioneered in the 1950s by Simon (1952), Tustin (1953), Phillips (1954) and Geyer and Oppelt (1957). Lange (1965) attempted an early synthesis. In the 1970s the idea became widespread and developed in two directions.
