The Cycles Driving Io’s Tectonics

Elements, 2022
Io is famous for its active volcanoes, but its vigorous tectonics, which are unlike Earth’s plate tectonics, are no less remarkable. The nature of Io’s thick, cold, brittle lithosphere has been revealed through decades of investigations. The dynamics of this system is most easily explained by considering three cycles: magmatic, tectonic, and sulfurous.

Regional driving characteristics, regional driving cycles

Transportation Research Part D: Transport and Environment, 2003
Abstract The Environmental Protection Agency’s (EPA) MOBILE6 driving cycles were developed by combining chase car data collected in three cities: Baltimore, Spokane, and Los Angeles, and then organizing the data by facility and level of service (LOS) to eliminate regional variability in driving.

Analysis of City Bus Driving Cycle Features for the Purpose of Multidimensional Driving Cycle Synthesis

SAE Technical Paper Series, 2020
<div class="section abstract"><div class="htmlview paragraph">Driving cycles are typically used for estimation of vehicle fuel/energy consumption and CO₂ emissions. In most of applications only the vehicle velocity vs. time profile is considered as a driving cycle, while a road slope is typically omitted.

Driving the Cell Cycle Through Metabolism

Annual Review of Cell and Developmental Biology, 2012
For unicellular organisms, the decision to enter the cell cycle can be viewed most fundamentally as a metabolic problem. A cell must assess its nutritional and metabolic status to ensure it can synthesize sufficient biomass to produce a new daughter cell.

Real-world European driving cycles, for measuring pollutant emissions from high- and low-powered cars

Atmospheric Environment, 2006
Pollutant emissions from cars are usually measured on a test bench using driving cycles. However, the use of one unique set of driving cycles to test all cars can be seen as a weak point of emission estimation, as vehicles could conceivably be tested ...

Alcohol consumption and cycling in contrast to driving

Accident Analysis & Prevention, 2017
In Germany, the legal blood alcohol limit for cyclists is much higher (0.16 percent) than the limit for drivers (0.05 percent) - as long as no crash has occurred. The proportion of police-recorded crashes with personal damage under the influence is higher for cyclists than drivers, and the blood alcohol concentrations are higher for cyclists than ...

How Proteolysis Drives the Cell Cycle

Science, 1996
Oscillations in the activity of cyclin-dependent kinases (CDKs) promote progression through the eukaryotic cell cycle. This review examines how proteolysis regulates CDK activity—by degrading CDK activators or inhibitors—and also how proteolysis may directly trigger the transition from metaphase to anaphase.

Using Large Driving Record Samples and a Stochastic Approach for Real-World Driving Cycle Construction: Winnipeg Driving Cycle

Transportation Science, 2014
The challenges in the development of plug-in electric vehicle (PEV) powertrains are efficient energy management and optimum energy storage, for which the role of driving cycles that represent driver behaviour is instrumental. Discrepancies between standard driving cycles and real driving behaviour stem from insufficient data collection, inaccurate ...

What Drives Glacial Cycles?

Scientific American, 1990
The Milankovitch theory advocates that the glacial cycles have three components: the tilt of the earth's spin axis; the shape of the earth's orbit; and the interaction between the tilt and the eccentricity effects. These three factors work together to vary the amount of sunshine reaching the high northern latitudes in summer and allow the great ice ...
