There are several examples of heuristic rules first proposed from empirical observation, which eventually earned physicochemical validity after the fundamental derivation of a posteriori. This may be the case of Sherwood’s plot – for which a sound rationalization from first principles, entailing enthalpy and mass balances, is provided here; it applies to (fine) chemicals undergoing concentr...

The computational insights illustrate the intramolecular hydrogen bonding/stability versus aromaticity analyses of a variety several sets multi-substituted OH/SH benzenes using quantifying approaches (NICS, HOMA, PDI, and AIBIC for aromaticity) (Relative Energy, HOMO-LUMO gap, QTAIM, HBSBIC stability/hydrogen bond strength) in framework density function theory (DFT) approach ab initio calculati...

Detrended Fluctuation Analysis (DFA) is widely used to assess the presence of long-range temporal correlations in time series. Signals with long-range temporal correlations are typically defined as having a power law decay in their autocorrelation function. The output of DFA is an exponent, which is the slope obtained by linear regression of a log-log fluctuation plot against window size. Howev...

Abstract Objectives The creamatocrit is a simple technique for estimating the lipid content of milk, widely adopted clinical and research purposes. We evaluated effect long-term cryogenic storage on human milk. Methods Frozen thawed milk specimens ( n = 18) were subjected to technique. reanalyzed after (10 years at <70°C). correlation between pre- post-storage values was tested, their differ...

We present a novel technique for motion-based recognition of individual gaits in monocular sequences. Recent work has suggested that the image self-similarity plot of a moving person/object is a projection of its planar dynamics. Hence we expect that these plots encode much information about gait motion patterns, and that they can serve as good discriminants between different types of gait. We ...
