Dialectics, Technoscience and Non-linearity

open access: yesTechnophany
Our article aims to analyse the significance of dialectics for philosophical reflection on technology. Drawing on the philosophy of Hegel, this article first of all reconstructs the progressive artefactualisation of thought and action, by indicating the

Non-equilibrium thermodynamics beyond linearity: sliding friction

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2019
Nevertheless, sliding friction is frequent and it was the first irreversible process we were faced in the school, very rare effort has been aimed to develop its non-equilibrium thermodynamic theory if ever. The reason may be guessed as Coulomb’s (Amonton’

Non‐linear osmosis

open access: yesThe Journal of Physiology, 1966
1. The relation between osmotic gradient and rate of osmotic water flow has been measured in rabbit gall‐bladder by a gravimetric procedure and by a rapid method based on streaming potentials. Streaming potentials were directly proportional to gravimetrically measured water fluxes.2.

On the non-linearity of the subsidiary systems

open access: yes, 2005
In hyperbolic reductions of the Einstein equations the evolution of gauge conditions or constraint quantities is controlled by subsidiary systems.

Approximate entropy as an indicator of non-linearity in self paced voluntary finger movement EEG [PDF]

open access: yes, 2013
This study investigates the indications of non-linear dynamic structures in electroencephalogram signals. The iterative amplitude adjusted surrogate data method along with seven non-linear test statistics namely the third order autocorrelation, asymmetry

Infection-induced cascading failures – impact and mitigation

open access: yesCommunications Physics
In the context of epidemic spreading, many intricate dynamical patterns can emerge due to the cooperation of different types of pathogens or the interaction between the disease spread and other failure propagation mechanism.

Phase Error Analysis and Correction for Crossed-Grating Phase-Shifting Profilometry

open access: yesSensors, 2021
Crossed-grating phase-shifting profilometry (CGPSP) has great utility in three-dimensional shape measurement due to its ability to acquire horizontal and vertical phase maps in a single measurement.

Stationary states of the Gross-Pitaevskii equation with linear counterpart

open access: yes, 2000
We study the stationary solutions of the Gross-Pitaevskii equation that reduce, in the limit of vanishing non-linearity, to the eigenfunctions of the associated Schr\"odinger equation.

Non-Gaussianity vs. non-linearity of cosmological perturbations

open access: yes, 2000
Following the discovery of the CMB, the hot big-bang model has become the standard cosmological model. In this theory, small primordial fluctuations are subsequently amplified by gravity to form the large-scale structure seen today.

Curvaton Dynamics and the Non-Linearity Parameters in Curvaton Model [PDF]

open access: yes, 2008
We investigate the curvaton dynamics and the non-linearity parameters in curvaton model with potential slightly deviating from the quadratic form in detail. The non-linearity parameter $g_{NL}$ will show up due to the curvaton self-interaction.
