Magnitude and Duration of Stretch Modulate Fibroblast Remodeling

Journal of Biomechanical Engineering, 2009
Mechanical cues modulate fibroblast tractional forces and remodeling of extracellular matrix in healthy tissue, healing wounds, and engineered matrices. The goal of the present study is to establish dose-response relationships between stretch parameters (magnitude and duration per day) and matrix remodeling metrics (compaction, strength, extensibility,

Driver sensitivity to brake pulse duration and magnitude

Ergonomics, 2007
Adaptive cruise control (ACC) requires that the driver intervene in situations that exceed the capability of ACC. A brake pulse might provide a particularly compatible means of alerting the driver to situations in which the acceleration authority of the ACC has been exceeded.

Duration Magnitude and Memory Resource Demand

NeuroQuantology, 2009
Whether duration magnitude modulates the cognitive resources required to represent that duration in memory is a fundamental question about the cognitive architecture of interval timing. The amplitudes of the Event-Related Potential (ERP) Slow Waves (SWs) elicited when participants maintain representations of different durations (e.g., 1500 versus 3000 ...

Estimating Magnitude and Duration of Incident Delays

Journal of Transportation Engineering, 1997
Traffic congestion is a major operational problem on urban freeways. In the case of recurring congestion, travelers can plan their trips according to the expected occurrence and severity of recurring congestion. However, nonrecurring congestion cannot be managed without real-time prediction.

METEOR ECHO DURATIONS AND VISUAL MAGNITUDES

Canadian Journal of Physics, 1956
The statistical relation between the radio echo duration and the visual magnitude has been investigated for approximately 3300 meteors observed on the combined Dominion Observatory–National Research Council program at Ottawa. Both echo durations and visual magnitudes were reduced to absolute values, defined as those for a meteor in the zenith at a ...
