Constancy of Relative Metabolic Rate

Relative constancy of urinary creatinine and urochrome.

Constancy of relative body weight in children.

Sohar, E., Scapa, E., and Ravid, M. (1973). Archives of Disease in Childhood, 48, 389. Constancy of relative body weight in children. The height and weight records of 404 schoolchildren at age 6 to 7 and at age 13 to 14 were analysed. Relative weight (i.e. % of ideal weight for height) of a child tended to change little over this period of 7 to 8 years of rapid growth. The correlation coefficie...

Entropy Rate Constancy in Text

We present a constancy rate principle governing language generation. We show that this principle implies that local measures of entropy (ignoring context) should increase with the sentence number. We demonstrate that this is indeed the case by measuring entropy in three different ways. We also show that this effect has both lexical (which words are used) and non-lexical (how the words are used)...

Relative colour cues improve colour constancy in birds.

A ripe strawberry looks red to our eyes in sunlight and in the green light of a forest, although the spectrum of light reflected from its surface differs dramatically. This is caused by two effects: colour constancy and our ability to learn relative colour cues - the ripe strawberry remains relatively 'redder' than an unripe green strawberry. While colour constancy - the ability to recognize co...

Constancy of pressure-rate product in pacing-induced angina pectoris.

The pressure-rate product during anginal pain produced by right atrial pacing was studied in 12 patients before, during, and after an angiotensin infusion sufficient to produce a significant rise in blood pressure. During the infusion the pain occurred at a significantly lower heart rate (P less than 0.001). However, the pressure-rate product was similar during anginal pain before and during th...
