"There are several possible explanations for these observations," the scientists wrote, "including the possibility" that the signals do not result from ice deposits.

The busy signal resulted, and indicated that he was home.

Because these signals result in cell growth and division, overactive Ras signaling can ultimately lead to cancer.

These signals can result in the restriction of blood flow to certain organs even without the vessels' necessarily being clogged by any material.

If that happens, an optical signal similar to that seen in the figure to the right will result.

This was so, other prosecutors said, because signals of violations by the devices sometimes do not result in arrest warrants for several days.

The signals result from interactions of the electron beam with atoms at or near the surface of the sample.

With each step of the cascade, the signal can be amplified, so a small signal can result in a large response.

Next Grady simply tried calling a mobile operator, but the same fast-busy signal resulted.

Then the signals result in a pattern of temporary but repetitious fading.
