Time Functions as Utilities [PDF]
Communications in Mathematical Physics, 2010 Every time function on spacetime gives a (continuous) total preordering of the spacetime events which respects the notion of causal precedence. The problem of the existence of a (semi-)time function on spacetime and the problem of recovering the causal structure starting from the set of time functions are studied.

Transactions of the American Mathematical Society, 1972 By regarding as equivalent any two real-valued functions of a real variable that can be obtained from each other by a monotone continuous transformation of the independent variable, time-free functions are defined. A convenient maximal invariant is presented, and applied to some time-free functional equations.

Physical healing as a function of perceived time
Scientific Reports, 2023 In this study we wounded study participants following a standardized procedure and manipulated perceived time to test whether perceived time affected the rate of healing.

Journal of Physics: Conference Series, 2017 In non-relativistic quantum mechanics of $N$ particles in three spatial dimensions, the wave function $\psi(q_1,\ldots,q_N,t)$ is a function of $3N$ position coordinates and one time coordinate. It is an obvious idea that in a relativistic setting, such functions should be replaced by $\phi((t_1,q_1),\ldots,(t_N,q_N))$, a function of $N$ space-time ...

Fitting a function to time-dependent ensemble averaged data [PDF]
, 2018 Time-dependent ensemble averages, i.e., trajectory-based averages of some observable, are of importance in many fields of science. A crucial objective when interpreting such data is to fit these averages (for instance, squared displacements) with a ...

The Time Augmented Cobb-Douglas Production Function
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2019 The main objective of this paper is to propose and verify a time augmentation of the Cobb-Douglas production function parameters which should be able to capture changing conditions over time.

Feel the Time. Time Perception as a Function of Interoceptive Processing
Frontiers in Human Neuroscience, 2018 The nature of time is rooted in our body. Constellations of impulses arising from the flesh constantly create our interoceptive perception and, in turn, the unfolding of these perceptions defines human awareness of time.

Radial Basis Function Nets for Time Series Prediction [PDF]
International Journal of Computational Intelligence Systems, 2009 This paper introduces a novel ensemble learning approach based on recurrent radial basis function networks (RRBFN) for time series prediction with the aim of increasing the prediction accuracy. Standing for the base learner in this ensemble, the adaptive

Equal-time correlation function for directed percolation
, 2010 We suggest an equal-time n-point correlation function for systems in the directed percolation universality class which is well defined in all phases and independent of initial conditions.
