Active Control of Hypertension
The Physician and Sportsmedicine, 1998Hypertension is common, and even slight elevations in blood pressure can be associated with health risks. Regular aerobic exercise helps prevent hypertension. In patients who already have hypertension, such exercise has been shown to lower systolic and diastolic blood pressure by a mean of 10 mm Hg.

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 ...

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 ...

Active networks is a new area of research which investigates how computations can be performed within the network elements. The philosophy behind the active network paradigm is to move away from the traditional OSI model where networks are a passive mover of data.

DIFFERENTIATION REQUIRES CONTINUOUS ACTIVE CONTROL
Annual Review of Biochemistry, 1992The problems posed by differentiation that appear most soluble by a passive control mechanism can readily be solved by an active mechanism. Given the need for plasticity in gene expression in different cell types at different stages, an active mechanism may be advantageous, even essential.

Inability to hide main memory latency has been increasingly limiting the performance of modern processors. The problem is worse in large-scale shared memory systems, where remote memory latencies are hundreds, and soon thousands, of processor cycles. To mitigate this problem, we propose an intelligent memory and cache coherence controller (AMC) that ...

An active control system is provided with an actuator which controls a noise and/or vibration state of an automotive vehicle, a detector which detects the noise and/or vibration state of the vehicle, and a control unit which receives an output signal of the noise and/or vibration state detector and outputs a signal to control the actuator, the control ...

We have argued in previous chapters that a distinction should be drawn between Goods Flow Control (GFC) and Production Unit Control (PUC). Goods Flow Control can be broken down into Aggregate Production Planning and Factory Coordination. Production Unit Control is also called Production Activity Control, see Figure 23.1. While GFC has been discussed in
