Connes' formula defines a distance in loop quantum gravity, via the spinfoam Dirac operator. A simple notion of spectral distance on a graph can be extended do the discrete Lorentzian context, providing a physically natural example of Lorentzian spectral geometry, with a neat space of Dirac ...
where d(K) is the distance from the starting point to the mark K. The geoid error variance at mark K is σN2(K)=E[θ(K)θ′(K)]=E[∫0d(K)ε(x)dx∫0d(K)ε(x′)dx′]=∫0d(K)dx∫0d(K)E[ε(x)ε(x′)]dx′=σ02d(K) (14) The root mean square of geoid error...
In order to calculate the luminosity distance, we have restricted the series of H(z) up to the tenth term, then integrating the approximate series to obtain the luminosity distance. The left panel of Fig. 9 displays the best fitting curve of our model compared with the ΛCDM model for ...

In blue, the enlarged area depicted in the main graph is indicated Full size imageConclusions A LCA was performed for a high-gravity technology in development that produces ethanol from spruce wood chips. The LCA was based on lab experiments in which a total of 30 different process ...
Figure 2 graph recent export and import data from France. These panels show deviations from the distance effect associated with Francophone countries, former colonies, and other members of the EU or of the Eurozone. The graph expresses the “spirit” of gravity: it identifies deviations from...

help of a clock that detects photons, which are reflected by a mirror at distanceDand return to the clock. Knowing the speed of light is universal, from the travel-time of the photon we can then extract the distance it has traveled. How precisely can we measure the distance in this way...
(𝐺𝑁 is the Newton’s constant, M is the total mass of the binary system, r is the binary constituents’ mutual distance, using natural units for the speed of light 𝑐=1), and n-PN corrections correspond to terms of the order 𝐺𝑛−𝑗+1𝑁𝑣2𝑗, with 0≤𝑗≤𝑛...
