Rather than varying along a single dimension, our experiences of hot and cold seem to vary in intensity in two directions around a neutral point (Gray 2012).
Our scheme selects for synchrony rather than entrainment: twice a day, we select the cells with high or low fluorescence, rather than varying an environmental cue and selecting for a response to it.
She also said in the interview that she preferred to set the limit at a single level for all Americans rather than varying it by income.
Andrew Read, an evolutionary biologist at Edinburgh University, wonders if different levels of sex hormones in promiscuous and monogamous monkeys, rather than varying exposure to sexually transmitted diseases, are responsible.
"Natural climate variability causes temperatures to wax and wane over a period of several years, rather than varying erratically from one year to the next," said Prof Michael Mann at Penn State university in the US, who led the new study.
Intuitively, for two neighboring points in the domain, sudden variation of the cost function with respect to both time delay criteria and attenuation model constraints is unlikely, and hence the resulting cost functions are usually expected to be rather slow varying and well behaved, away from the sensors.
Some people believe that the very distinction between permanent and temporary migration is breaking down, and that we will soon be living in a world of "superdiversity" with a multitude of legal statuses that are neither wholly temporary nor wholly permanent, but rather have varying degrees and levels of conditionality and precariousness (Vertovec, 2007, 2016).
Also flawed are some utterly perplexing charts and graphs that are meant to amplify the text; they might benefit from color rather than varying shades of gray.
A few studies have examined dose responses in the immune response to Ovalbumin, but using different immunizing doses, rather than varying the respiratory exposure.
