We study the fluctuations of eigenstate expectation values in a microcanonical ensemble. Assuming thermalization hypothesis, an analytical formula for finite-size scaling is derived. The same problem was studied by Beugeling et al. (2014). compare our results with theirs.

The statistical synthesis of quantitative effects within primary studies via meta-analysis is an important analytical technique in the scientific toolkit modern researchers. As with any method or technique, knowledge weaknesses that might render findings limited potentially erroneous as well strategies by which to mitigate these biases essential for high-quality evidence. In this paper, we focu...

spotted amber ladybird, hippodamia variegata (goeze, 1777) (coleoptera: coccinellidae) is an important predator of aphids and some other insect pests. since shape and size variation may affect biological characteristics of an insect, multivariate analysis of shape variations in four geographically isolated populations of h. variegata (isfahan, shahrekord, shiraz, yasuj) was performed based on e...
