Epistemological Suggestions in „Entropy Low and Economic Process” [PDF]

open access: yesTheoretical and Applied Economics, 2006
The paper is aimed to derive, on criticism basis (following, especially, the critic rationalism, as method), epistemological suggestions from the crucial work of Nicholas Georgescu-Roegen, “The Entropy Law and the Economic Process”, in order to these ...

Remarks on the Compatibility of Opposite Arrows of Time II

open access: yesEntropy, 2006
In a series of papers [1,2,3], Lawrence Schulman presented examples which demonstrate the compatibility of opposite arrows of time in various situations.

Discovering the Arrow of Time in Machine Learning

open access: yesInformation, 2021
Machine learning (ML) is increasingly useful as data grow in volume and accessibility. ML can perform tasks (e.g., categorisation, decision making, anomaly detection, etc.) through experience and without explicit instruction, even when the data are too ...

Hydrophobic Mesoporous Silica-Coated Solid-Phase Microextraction Arrow System for the Determination of Six Biogenic Amines in Pork and Fish

open access: yesFoods, 2023
In this study, a functionalized mesoporous silica-coated solid-phase microextraction (SPME) Arrow system was developed for the enrichment of six biogenic amines (BAs) from pork and fish samples before gas chromatographic separation with a mass ...

Relating the thermodynamic arrow of time to the causal arrow [PDF]

open access: yesJournal of Statistical Mechanics: Theory and Experiment, 2008
Consider a Hamiltonian system that consists of a slow subsystem S and a fast subsystem F. The autonomous dynamics of S is driven by an effective Hamiltonian, but its thermodynamics is unexpected. We show that a well-defined thermodynamic arrow of time (second law) emerges for S whenever there is a well-defined causal arrow from S to F and the back ...

Alternative interpretation of relativistic time-reversal and the time arrow

open access: yesPhysical Review Research, 2022
It is well known that the 4-rotation in four-dimensional space-time is equivalent to the CPT transformation (C is the charge conjugation, P is the space inversion, and T is the time reversal). The standard definition of the T reversal includes the change

Length of Time’s Arrow

open access: yesPhysical Review Letters, 2008
An unresolved problem in physics is how the thermodynamic arrow of time arises from an underlying time reversible dynamics. We contribute to this issue by developing a measure of time-symmetry breaking, and by using the work fluctuation relations, we determine the time asymmetry of recent single molecule RNA unfolding experiments.

Seeing the Arrow of Time

open access: yes2014 IEEE Conference on Computer Vision and Pattern Recognition, 2014
We explore whether we can observe Time's Arrow in a temporal sequence -- is it possible to tell whether a video is running forwards or backwards? We investigate this somewhat philosophical question using computer vision and machine learning techniques. We explore three methods by which we might detect Time's Arrow in video sequences, based on distinct ...

Temporal Arrows in Space-Time [PDF]

open access: yes, 2013
The prevailing current of thought in both physics and philosophy is that relativistic space-time provides no means for the objective measurement of the passage of time. Kurt Gödel, for instance, denied the possibility of an objective lapse of time, both

Learning the Arrow of Time

open access: yesCoRR, 2019
We humans seem to have an innate understanding of the asymmetric progression of time, which we use to efficiently and safely perceive and manipulate our environment. Drawing inspiration from that, we address the problem of learning an arrow of time in a Markov (Decision) Process.
