We report the first measurement of genus curves for the two-dimensional mass map in the neighborhood of rich, X-ray luminous galaxy cluster MS1054-03 at z = 0.83, reconstructed from weak lensing data obtained by Suprime-Cam on the prime focus of 8.2m Subaru telescope . We find that the genus curve measured in the whole survey field deviates from that expected from a random Gaussian field. We sh...

We analyze how individual eigenvalues of the QCD Dirac operator at nonzero quark chemical potential are distributed in the complex plane. Exact and approximate analytical results for both quenched and unquenched distributions are derived from non-Hermitian random matrix theory. When comparing these to quenched lattice QCD spectra close to the origin, excellent agreement is found for zero and no...

Molecular phylogenetics and its applications are popular and useful tools for making comparative investigations in genetics; however, estimating phylogenetic trees is not always straightforward. Some phylogenetic estimators use an explicit model of nucleotide evolution to estimate evolutionary parameters such as branch lengths and tree topology. There are many models to choose from, and use of ...

background in recent years, accreditation of private hospitals followed by decentralisation of the italian national health service (nhs) into 21 regional health systems has provided a good empirical ground for investigating the tiebout principle of “voting with their feet”. we examine the infra-regional trade-off between greater patient choice (due to an increase in hospital services supply) an...

when the tunisian revolution triggered the domino of the collapse arab leaders, it was not anticipated to reach to syria creating a deep conflict with local, regional and trans-regional dimensions. however, when the protests speared to syria, various players try to exploit it to their own advantage, and an all-out conflict began. due to syria's geopolitical location, regional powers such as ira...
