The distributions of a wide variety of physical, biological, and human-made phenomena approximately follow a power law over a wide range of magnitudes: these include the sizes of craters on the moon and of solar flares, [2] cloud sizes, [3] the foraging pattern of various species, [4] the sizes of activity patterns of neuronal populations, [5] the frequencies of words in most languages ...
Critics of the power law also point out that the validity of the law is contingent on the measurement of perceived stimulus intensity that is employed in the relevant experiments. ( Luce 2002 ), under the condition that respondents' numerical distortion function and the psychophysical functions could be separated, formulated a behavioral ...
Any non-linear differentiable function, (,), of two variables, and , can be expanded as + +. If we take the variance on both sides and use the formula [11] for the variance of a linear combination of variables (+) = + + (,), then we obtain | | + | | +, where is the standard deviation of the function , is the standard deviation of , is the standard deviation of and = is the ...
In thermodynamics, the thermodynamic free energy is one of the state functions of a thermodynamic system (the others being internal energy, enthalpy, entropy, etc.).The change in the free energy is the maximum amount of work that the system can perform in a process at constant temperature, and its sign indicates whether the process is thermodynamically favorable or forbidden.
BUENOS AIRES (Reuters) -An Argentine court dismissed aggravated rape charges against French international rugby players Hugo Auradou and Oscar Jegou on Tuesday, drawing a line under a dark period ...
The most fundamental concept in chemistry is the law of conservation of mass, which states that there is no detectable change in the quantity of matter during an ordinary chemical reaction. Modern physics shows that it is actually energy that is conserved, and that energy and mass are related; a concept which becomes important in nuclear chemistry.
Markets shook off any concern Tuesday about rising tensions between Russia and the United States. The Dow ended the day down by 120 points, or 0.28%, after a volatile start.
