jerks are part of a more complex behavior of the field, namely the superposition of variations at the 22- and ~80-year timescales on a steady variation, as a result of superimposed surface effects of core processes at several timescales.
The jerks should be regarded as parts of a more complex behavior of the field, namely the superposition of variations at the 22- and ~80-year timescales on a steady variation, as a result of superimposed surface effects of core processes at several time scales.
Secular variation studies developed by Demetrescu and Dobrica (2005, 2014) and Dobrica et al. (2013) on long time series (100 150 years) of observatory data showed that the surface field and its SV are constituted of oscillations at time scales of ~ 11, ~ 22 and ~ 80 years, which are superimposed on a (quasi linear trend denoted steady variation.
The latter is further filtered with a 80-year running averages filter to obtain what we call the steady variation (E80).
Several conclusions could be drawn regarding the secular change of the internal field, having at hand the longer time perspective on data plotted in Fig. 8: (1) the first time-derivative does not show jerks, but display extrema of the combined ~80-year, 22-year, and steady variations; this was first shown on D data by Demetrescu and Dobrica (2005, 2013).
Chronic pain activity induces steady variations in interneuronal transmission that could alter motor strategies [ 16].
Such comparisons revealed significant signatures (with steady variations of mean values, either increasing or decreasing) between the three following groups: a merged group associated with hyperthermophiles and thermophiles (HTH-TH); a merged group associated with prokaryotic mesophiles and psychrophiles (PMES-PSYC) and finally eukaryotes (EUK).
They don't rely on big hits, industry analysts say, just a steady stream of variations on classic toys mostly for children up to the age of 5. Nonetheless, their business has grown by double digits every year, to an estimated $325 million in revenue this year from $100 million in 2008 (and to 650 employees from 200), according to a toy company executive familiar with the company's operations.
The slow movement is a steady flow of variations with moments that foreshadow the great last movement.
Typically, plume models assume a steady state, with variations in source and atmospheric conditions occurring on timescales that are much longer than the timescale for motions in the plume.
A steady increase of genetic variation through increasing taxonomic levels was observed, supporting a marked change of genetic divergence at the species boundaries (Figure 2A).
