Since it was the first time that this mechanism was observed at such a scale in a relatively developed country, it was called «Dutch disease.»

But the brain synchrony we were observing was at such high time - scales — of three to nine oscillations per second — that we still need to figure out how exactly eye gaze and vocalisations create it.»

Lead researcher Dr Morgan Beeby said: «We are used to observing evolution at the scale of animals or plants, such as the giraffe's neck slowly getting longer over time to reach previously inaccessible food.

Such collisional avalanches can happen very quickly — consistent with the time scales observed at TYC 8241 2652.

«On a bigger scale, sensors could be placed at different locations at catchment scale to observe any changes in the level of salinity within a field over time, having a direct impact on irrigation strategies.

Dr. Yu's research has evolved to understand interfacial phenomena at the fundamental atomic and molecular level that are relevant to the observed changes across multiple time and space scales in the environment, with implications in biological systems (e.g., biofilm and cell), aerosol, catalysis, and materials.

[34] The light curve of B varies on a short time scale and there has been at least one observed flare.

The geometric homeostasis of mature epithelia observed at short enough time - scale thus raises the problem to understand how cells, if considered as noisy individual actuators, do adapt across individual intercellular contacts to locally balance their time - average contractile stress.

While neural oscillations entrain to the dynamics of speech at distinct time scales, it is yet unclear whether neural entrainment observed across studies and frequency ranges reflect the same underlying mechanism.

---- Concurrent - Related Evidence of Validity: Concurrent - related evidence of validity is observed when, in this case, large - scale standardized test and other criterion data are collected at the same time.

That's one thing, but the model variability at a 10 - year time scale encompasses the observed surface trends, even for HadCRUT3 which probably warms too little.

Detailed statistics for observed and modelled temperature time series at Albany on climatic scale.

Even a perfect model can deviate significantly from past observed trends or changes, just because the physical system allows variability at decadal time scales; the climate and its trend that we're experiencing is just one of the many climates that we could have had.

Such Hurst phenomena have been observed in the stochastic processes of nature in the area of hydrology (Hurst) and also in the proxy record of annual mean surface temperature at a millennial time scale (Barnett).

Change to atmospheric carbon dioxide concentration is observed to follow change to global temperature at all time scales.

But there is a statistical implication, namely that it is a time scale of averaging at which new properties emerge in the average that are not observed in the raw observations.

This corresponds nicely to what would be expected from models (see, e.g., the EPICA Challenge) and is not unreasonably different from the sensitivity observed at shorter time scales, as Ferdinand Engelbeen noted.

But it would have exactly the consequence that I said: the natural, preanthropogenic variability at the relevant time scale (decades, centuries, millennia), which is precisely related to the amplitude of the FT at this frequency, should be much lower than the observed signal.

There continues to be very high confidence that models reproduce observed large - scale mean surface temperature patterns... There is high confidence that regional - scale surface temperature is better simulated than at the time of the AR4.

A study of observational data sets from the World Glacier Monitoring Service (WGMS) concluded that «rates of early 21st - century mass loss are without precedent on a global scale, at least for the time period observed and probably also for recorded history» (Zemp et al. 2015).

Several analyses of ring width and ring density chronologies, with otherwise well - established sensitivity to temperature, have shown that they do not emulate the general warming trend evident in instrumental temperature records over recent decades, although they do track the warming that occurred during the early part of the 20th century and they continue to maintain a good correlation with observed temperatures over the full instrumental period at the interannual time scale (Briffa et al., 2004; D'Arrigo, 2006).

The Karnofsky scale was reportedly valid and reliable in several patient populations.21 In this study good agreement was observed between two raters in the allocation of patients to the specified outcome categories (Cohen's (kappa) greater than 0.8 at every time point).22 Subsidiary measures of functioning included a patient rating of interference with daily activities, 23 improvement in employment status, and number of days spent in bed each week.
