By this he meant that although inorganic matter was inevitably subject to entropy, (all the structure of peaks and valleys puddling out into a flat line of cosmic death) organic matter, life, had a reverse drive for higher and higher complexities, from the amoebae to the whale brain.

There is a lot of room for a high level of entropy there to throw Cro Cop off of his trail.

The molecules in a hot gas, for example, can be arranged in many different ways to create the same overall temperature and pressure, making the gas a high - entropy system.

Wang's research group designed a five - metal catalyst based on these high - entropy - alloy nanoparticles and demonstrated superior catalytic performance for selective oxidation of ammonia to nitrogen oxide, a reaction used by the chemical industry to produce nitric acid, an important chemical in the large - scale production of fertilizers and other products.

This method is ideally suited for so - called high - entropy alloys — materials that have recently been of great interest to researchers.

As a proxy for splicing alteration, we computed the Shannon's entropy on the relative abundance of a gene's alternative splicing isoforms (Methods)-- higher values corresponding to more stochastic production of alternative isoforms.

Chemotherapeutic Dose Scheduling Based on Tumor Growth Rates Provides a Case for Low - Dose Metronomic High - Entropy Therapies, Cancer Research (2017).

The program will assist and inform other ongoing materials research projects at Ames Laboratory, including ones with experimentalists on the hunt for new magnetic and high - entropy alloys, thermoelectrics, rare - earth magnets, and iron - arsenide superconductors.

But everything else is the aptly named «high configurational entropy» which has for consequence an impossibility of validation.

Tomas, the high configurational entropy thing is intriguing, do you have specific references for this idea that provides more explanation?

See Curry post on «Nonequilibrium thermodynamics and maximum entropy production in the Earth system» paper by Axel Kleidon (downloadable) https://judithcurry.com/2012/01/10/nonequilibrium-thermodynamics-and-maximum-entropy-production-in-the-earth-system/ «The Earth system is maintained in a unique state far from thermodynamic equilibrium, as, for instance, reflected in the high concentration of reactive oxygen in the atmosphere.

For the sake of his proof, Dr. Brown assumes (as he and most of us believe, contrary to fact) that at equilibrium, i.e., in the highest - probability, highest - entropy state, the isolated gas column exhibits the dry adiabatic lapse rate.

I don't understand the reasoning by which it is held to be impossible for the sensitivities to be different — after all, solar energy is very short wave length, low - entropy while IR is long wave and high entropy so conceptually different sensitivites seem possible to me, but I haven't investigated the matter in detail.

One billion atomic bombs has a very low entropy, but 2.5 trillion 100 watt light bulbs spread evenly over the Earth, and operating for a decade has a very high entropy.

RMSSD is sensitive to high - frequency heart period fluctuations in the respiratory frequency range and is used as an index of vagal cardiac control.3) In the frequency - domain analysis, the power spectra of three frequency bands are calculated: very low frequency (VLF; 0.005 - 0.040 Hz), low frequency (LF; 0.04 - 0.15 Hz), high frequency (HF; 0.15 - 0.40 Hz), and total power (TP), including VLF, LF, and HF.1) For the non-linear complexity measure, the approximate entropy (ApEn) is calculated.4) The ApEn is a parameter that was developed to quantify the degree of regularity versus unpredictability in a higher dimensional attractor reconstructed from a time series, such as the instantaneous heart rate time series.5, 6) A lower ApEn value reflects a higher degree of regularity, and the higher the entropy value, the more unpredictable the time series.5, 6)
