We show how to construct space time lattices with a Regge action proportional to the energy of a given Ising or Potts model macrostate. This allows to take advantage of the existence of exact solution...
Analysis of 3D MHD Instability of Antisolar Latitudinal Differential Rotation in F, G and K stars
Analysis Instability Latitudinal Differential Rotation

2011/10/8
Motivated by observations that only a very few stars have been found to have antisolar differential rotation, much weaker in amplitude than that of the Sun, we analyze the stability of antisolar and s...

In the distributed burning regime, turbulence disrupts the internal structure of the flame, and so the idea of laminar burning propagated by conduction is no longer valid. The nature of the burning de...
Chemical abundance analysis of the Open Clusters Berkeley 32, NGC 752, Hyades and Praesepe
Stars: abundances – Galaxy: disc – Galaxy: open clusters and associations: individual: NGC 752 Hyades Berkeley 32 Preasepe (M 44)

The XENON100 dark matter experiment uses liquid xenon (LXe) in a time projection chamber (TPC) to measure Xe nuclear recoils resulting from the scattering of dark matter Weakly Interacting Massive Par...
Spectral Energy Distribution variation in BL Lacs and FSRQs
Radiation mechanisms: non-thermal – Galaxies: active – BL Lacertae objects: general
