Shiyang says the open source factor alone could be enough to explain Android's success, but ABI also notes that growth in iPhone shipments slowed in the middle of 2011, likely as consumers decided to wait to buy a new iPhone until the next model (which we now know to be the iPhone 4s) was released.

In winter, comparisons of source factor and component associations with cardiac end points were somewhat internally consistent, although less so for rMSSD than for HR.

We test for robustness by computing indices with widely-varying weights to reflect relative emphasis on energy resources (renewable and nonrenewable), impact vulnerability (sea level rise; weather damage); neutrality (equal weights); positive source factors (renewable energy; sequestration potential) and negative source factors (nonrenewable energy, employment vulnerability).

Other Physical Conversion Factors multiplied Energy Source Original Unit by Petroleum barrels (bbl) x Coal short tons x long tons x metric tons (t) x Wood cords (cd) x cords (cd) x Conversion Energy Source Factor equals Final Unit Petroleum 42(a) = U.

Alternatively, we added the estimated mass for each of the source factor scores (in micrograms per cubic meter) simultaneously in the model.

We extracted daily counts of deaths from National Center for Health Statistics records and estimated city-specific associations of mortality with each source factor by Poisson regression, adjusting for time trends, weather, and the other source factors.
