Alternative interpretation of relativistic time-reversal and the time arrow
Physical 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

Foods, 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 ...

Opposite Thermodynamic Arrows of Time [PDF]
AIP Conference Proceedings, 1999 A model in which two weakly coupled systems maintain opposite running thermodynamic arrows of time is exhibited. Each experiences its own retarded electromagnetic interaction and can be seen by the other. The possibility of opposite-arrow systems at stellar distances is explored and a relation to dark matter suggested.

Fluctuation, Dissipation and the Arrow of Time
Entropy, 2011 The recent development of the theory of fluctuation relations has led to new insights into the ever-lasting question of how irreversible behavior emerges from time-reversal symmetric microscopic dynamics.

2014 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 ...

Beyond the Arrow of Time: Can There Be a Relation between the Measurement of Entropy and Time?
Proceedings, 2017 The general tendency of the entropy of an isolated to increase is considered to be directly linked to the direction of the flow of time. This raises the question whether a quantitative relation can be established such that a time interval can be measured

Solid-Phase Microextraction Arrow for the Sampling of Volatile Organic Compounds in Milk Samples
Separations, 2020 A novel sample preparation method based on the use of the Arrow solid-phase microextraction device was used to extract and preconcentrate volatile organic compounds (VOCs) from milk samples prior to their determination by gas chromatography–mass ...

A note on singularities and the arrow of time [PDF]
Serbian Astronomical Journal, 2000 An interesting thought experiment claiming to highlight the connection between singularities and the global arrow of time is re-analyzed, and a further specification suggested.

The Cosmological Arrow of Time and the Retarded Potentials
Universe, 2022 We demonstrate that the cosmological arrow of time is the cause for the arrow of time associated with the retarded radiation. This implies that the proposed mathematical model serves to confirm the hypothesis of Gold and Wheeler that the stars radiate ...

Changing the load of a arrow crane while carrying out loading and unloading works [PDF]
Научно-технический вестник Брянского государственного университета, 2020 The stability of self-propelled jib cranes is a key task in the process of their operation. The developed calculation scheme of the arrow self-propelled crane and the restrictions imposed on its movement in time and space, allowed to obtain mathematical ...
