Real-time rapid prediction of variations of Earth’s rotational rate

Science Bulletin, 2008
Real-time rapid prediction of variations of the Earth’s rotational rate is of great scientific and practical importance. However, due to the complicated time-variable characteristics of variations of the Earth’s rotational rate (i.e., length of day, LOD), it is usually difficult to obtain satisfactory predictions by conventional linear time series ...

Quasars Revisited: Rapid Time Variations Observed Via Very-Long-Baseline Interferometry

Science, 1971
Recent Goldstone-Haystack radio interferometric observations of the quasars 3C 279 and 3C 273 reveal rapid variations in their fine structure. Most notably, the data for 3C 279, interpreted in terms of a symmetric double-source model and the accepted red-shift distance, indicate differential proper motion corresponding to an apparent speed about ten ...

Observations and interpretation of spectra and rapid time variations of type-B aurora

Planetary and Space Science, 1979
Abstract Observations of type-B red and normal aurora were made with a high-speed multichannel photometer and a digital grating spectrometer. The ratio I ( O 2 + 1N; 2, 0 + 3, 1) I ( N 2 + 1N; 0, 3) measured in the 5200–5300 A region with the spectrometer was found to increase by about 16% from normal to type-B ...

Rocuronium Versus Succinylcholine for Rapid-Sequence Induction Using a Variation of the Timing Principle

Survey of Anesthesiology, 1997
To determine if, using a variation of the "timing" principle, 0.6 mg/kg of rocuronium can achieve an onset time and intubating conditions similar to those achieved with succinylcholine.Prospective, randomized, double-blind clinical comparison.Operating room in a university medical center.42 ASA physical status I and II patients undergoing general ...

Rapid Time Variations in Chemical Composition of Precipitation in South Korea

Water, Air, and Soil Pollution, 2001
Data from a monitoring program on precipitation at four sites in South Korea during the period from 1993 to 1998 were analyzed for determining a time trend relationship in chemical composition of precipitation. The concentrations of nss-sulphate, ammonium and calcium were found to have decreased over time at a statistically significant level in Seoul ...

Time‐of‐Day Variation in Learning, Reward‐Associated Behaviors, and in Rapid Dopamine Signaling

The FASEB Journal, 2020
Approximately one in five adults in the United States suffers from at least one psychiatric disorder. Research has shown that biological rhythms in physiology and behavior play a role in a number of psychiatric disorders, like depression and substance use disorder (SUD). For example, time‐
