Abrupt dips in some walls indicated destruction by earthquake.
The historic temperature pattern we observed has abrupt dips that match the emissions of known explosive volcanic eruptions; the particulates from such events reflect sunlight, make for beautiful sunsets and cool the earth's surface for a few years.
Some of them will be soothed by news that the Securities and Exchange Commission, the main financial-markets watchdog, wants to make it harder for "professional plaintiffs" to win securities class actions (in which investors band together to sue listed firms over accounting irregularities or abrupt dips in the share price).
At ∣Δθ∣⪡1, the spectrum of transmission (without mode conversion) represents a nearly periodic group of abrupt dips to zero and a modulated group of secondary drops increasing with growing 2N2, whereas the general spectral background is close to unity.
But this abrupt fall of global figures reflects the drastic shrinking of supplies, not a dip in demand, which remains as strong as it has ever been, in a striking parallel to what is happening in the art market.
Phrases in one register were interrupted by sudden, ear-splitting shrieks, abrupt one-note dips into an ominous baritone and full-tilt hollers.
Around the Fano dip, the transmission coefficient suffers an abrupt change leading to an increase in the thermopower.
Usually such structures produce locally very steep dips, strong lateral variations in velocity and abrupt truncation of the reflectors.
When given to patients with stable angina or acute coronary syndromes, intracoronary DIP before percutaneous transluminal coronary angioplasty was reported to reduce the risk of abrupt vessel closure [ 5, 6].
We found that the PSMC is unable to reconstruct abrupt changes in N e: for example, instantaneous bottlenecks 2000 or 20,000 years ago are reconstructed as a gradual dip in N e over a period of 5000 or 50,000 years, respectively.
