We distinguished the two different uses of factive and NonFactive (NF) in the verb al-ta ‘know’ in Korean and the distinction is crucially made by the different complement cases of factive –ul ACC and NF –uro Directional (oblique). The NF use is possible with nonveridical/negative contexts in English and other languages but it is possible with a positive sentence with the Directional case in Ko...

This paper aims at obtaining performance limitations of state estimation in terms of variance minimization (minimum variance estimation and filtering) using information theory. Two new notions, negentropy rate and Gaussianity-whiteness measure (joint Shannon-Wiener entropy), are proposed to facilitate the analysis. Topics such as Gaussianing-whitening filter (the maximum Gaussianity-whiteness m...

The purpose of this note is to express my concerns about the published paper by Quarati et al. (Entropy 2016, 18, 63). It is hoped that these comments will stimulate a constructive discussion of the issues involved. The above paper by Quarati et al. [1] argues that the concept of negentropy can be useful in understanding the observed enhancements of nuclear fusion rates in the solar plasma and ...

evaluation criteria for different versions of the same database the concept of information, during its development, is connected to the concept of entropy created by the 19th century termodynamics scholars. information means, in this view point, order or negentropy. on the other hand, entropy is connected to the concepts as chaos and noise, which cause, in turn, disorder. in the present paper, ...

This paper is an attempt to develop the new discipline of ecodynamics as a quest for evolutionary physics and ecoinformatics. Particular attention is devoted to goal functions, to relation of conceptualizations surrounding matter, energy, space and time and to the interdisciplinary approach connecting thermodynamics and biology. The evolutionary dynamics of complex systems, ranging from open ph...

Scientists have been successful in cataloguing genes through genome sequencing projects, and they can now generate vast quantities of gene expression data using microarrays. However, due to the sheer size of the data sets involved, and to complexity of the problems to be tackled, the biological comunity has so far had less success in understanding how genes and proteins are connected and how th...

We present a robust algorithm for independent component analysis that uses the sum of marginal quadratic negentropies as a dependence measure. It can handle arbitrary source density functions by using kernel density estimation, but is robust for a small number of samples by avoiding empirical expectation and directly calculating the integration of quadratic densities. In addition, our algorithm...

We study the relation between the discrete-time version of the flashing ratchet known as Parrondo’s games and a compression technique used very recently with thermal ratchets for evaluating the transfer of information— negentropy — between the Brownian particle and the source of fluctuations. We present some results concerning different versions of Parrondo’s games showing, for each case, a goo...
