We study analytically the phase diagram of the pure SU (N) lattice gauge theory at finite temperature, and we attempt to estimate the critical decon-finement temperature. We apply large N techniques to the Wilson and to the Heat Kernel action, and we study the resulting models both in the strong coupling and in the weak coupling limits. Using the Heat Kernel action, we establish an interesting ...

Nach den jüngsten Ausbrüchen der Maulund Klauenseuche (MKS) in Europa wird die Notimpfung als eine alternative Bekämpfungsmaßnahme zur präventiven Keulung diskutiert. Mit Hilfe eines räumlichen und zeitlichen MonteCarlo Simulationsmodells für die Übertragung des MKS-Virus zwischen Tierbeständen wurden diese beiden Kontrollmaßnahmen miteinander verglichen und auch Interaktionen mit weiteren Einf...

A fully relativistic quark model is constructed and applied to the study of wave-functions as well as the spectrum of heavy-light mesons. The free parameters of the model are a constituent quark mass and (on the lattice) an adjustable r-parameter in the fermionic kinetic energy, while the confinement is introduced via potentials measured by MonteCarlo. The results are compared to Monte Carlo en...

We investigate and compare two dual formulations of the American option pricing problem based on two decompositions of supermartingales: the additive dual of Haugh and Kogan (Oper. Res. 52:258–270, 2004) and Rogers (Math. Finance 12:271–286, 2002) and the multiplicative dual of Jamshidian (Minimax optimality of Bermudan and American claims and their MonteCarlo upper bound approximation. NIB Cap...

ollaborations with the MXL utilizing Small Angle X-ray Scattering (SAXS) have yielded new insight about the proteins being studied. While crystallization results in a static picture of a single conformation of your protein, and NMR is generally restricted to a single molecule of limited size, in solution your molecule may adopt one, two, or several conformations. Cryo-EM offers one method of im...
