Emergence of Time
In the groupoid approach to noncommutative quantization of gravity, gravitational field is quantized in terms of a C-algebra A of complex valued functions on a groupoid G = E ×Γ, where E is a suitable space and Γ a group of fundamental symmetries. In the noncommutative quantum gravitational regime the concepts of space and time are meaningless. We study the “emergence of time” in the transition...
متن کاملEffect of Water and Temperature on Seed Germination and Emergence as a Seed Hydrothermal Time Model
The physiological process of germination depends on several environmental factors such as temperature, water potential, light, nutrients and smoke. Water and temperature are determinant factors for seed germination. Both factors can, separately or jointly, affect the germination percentage and germination rate. The effect of temperature on germination and water potential on germination canoften...

متن کاملTime of emergence of climate signals
The time at which the signal of climate change emerges from the noise of natural climate variability (Time of Emergence, ToE) is a key variable for climate predictions and risk assessments. Here we present a methodology for estimating ToE for individual climate models, and use it to make maps of ToE for surface air temperature (SAT) based on the CMIP3 global climate models. Consistent with prev...
متن کاملContinuous-time trading and emergence of volatility
This note continues investigation of randomness-type properties emerging in idealized financial markets with continuous price processes. It is shown, without making any probabilistic assumptions, that the strong variation exponent of non-constant price processes has to be 2, as in the case of continuous martingales.
