<div class="section abstract"><div class="htmlview paragraph">The stringent emission regulations have put enormous pressure on auto manufacturers to develop vehicles with the required conformity factor (CF) on real driving emissions (RDE). However, evaluation of CF on multiple and varying real-world cycles by portable emission measurement ...

Driving the Cell Cycle to Cancer
2003Cell cycle progression requires the co-ordinated activation of several kinases, some of which are activated upon the binding of a cyclin subunit. At least four of these so-called cyclin-dependent kinases, namely Cdk4, Cdk6, Cdk2 and Cdk1, have specific roles at particular stages of the cell cycle, including passage through the various cell cycle ...

Abstract A survey of morning peak driving patterns in Sydney was carried out using an instrumented vehicle. Speed histories were recorded and the data were analyzed to determine the statistics and the expected vehicle emissions for Sydney. A comparison with the U.S.

The Cycles Driving Io’s Tectonics
Elements, 2022Io 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, 2003Abstract 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.

<div class="section abstract"><div class="htmlview paragraph">Driving cycles are typically used for estimation of vehicle fuel/energy consumption and CO<sub>2</sub> 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, 2012For 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.

Alcohol consumption and cycling in contrast to driving
Accident Analysis & Prevention, 2017In 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, 1996Oscillations 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.

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 ...
