Two notes of caution are warranted, though. First, while the idea of a safe haven is tempting, a long history of financial markets shows us that there is no such thing as the ‘perfect’ safe haven. There has been at least one instance where each so-called safe haven asset class has ...
The mean flare duration is similar to 6 minutes with a 1 minute minimum set by the flare-finding algorithm. The frequency distributions of the peak count rate in the energy bands, 3-6, 6-12, and 12-25 keV, can be represented by power-law distributions with a negative power-law index ...
NT neural threshold RMS root-mean square SNR signal-to-noise ratio SIN speech-in-noise SD standard deviation TFS temporal fine structure 1. Introduction Speech processing in humans is a complex process based on the integration of spectral and temporal information, where temporal information can be ...
The Central Limit Theorem implies that the mean of a population can be estimated by the sample means. Learn the definition and implications of the theorem and explore how probabilities in opinion polls are determined using the Central Limit Theorem. ...
{OFI}}}\)is the mean firing rate of the optic flow integrator (OFI) population. This guarantees that the velocity is adapted to the level of clutteredness, ensuring slow movement in complex environments. During this movement phase, called intersaccade, the agent integrates translational OF inform...
Structural defects control the kinetic, thermodynamic and mechanical properties of glasses. For instance, rare quantum tunneling two-level systems (TLS) govern the physics of glasses at very low temperature. Due to their extremely low density, it is very
Where multiple values were returned (such as with velocity which was determined at each time step), a statistical summary was computed for those properties for each track segment. The statistical summary consisted of the mean, median, standard deviation, 1st quartile, 3rd quartile, kurtosis (a ...
Furthermore, there was an outlier in February 2016 with very low backscattering coefficients and it was associated with a drought year. Finally, predicting the amplitude of July 2020 returned high relevant Root Mean Square Error (rRMSE). Seven years of time series data are limiting for predicting...
