The effects of multi-photon-exchange and other higher-order QED corrections on elastic electron-proton scattering have been a subject high experimental theoretical interest since the polarization transfer measurements proton electromagnetic form factor ratio $$G_E^p/G_M^p$$ at large momentum $$Q^2$$ conclusively established strong decrease this with for $$Q^2 \gtrsim 1$$ $$\hbox {GeV}^2$$ . Thi...
A series of measurements of single pion electroproduction on the proton, deuteron, and He was completed recently at Je erson Laboratory by the NucPi Collaboration. The data form the rst part of a study of longitudinal electroproduction in light nuclei. The goal is a determination of the longitudinal cross section in parallel kinematics by means of a Rosenbluth separation, and a search for targe...
The scaling behavior of linear polymers in disordered media, modelled by self-avoiding walks (SAWs) on the backbone of percolation clusters in two, three and four dimensions is studied by numerical simulations. We apply the pruned-enriched Rosenbluth chain-growth method (PERM). Our numerical results yield estimates of critical exponents, governing the scaling laws of disorder averages of the co...
The travel agency industry is currently experiencing profound changes such as commission caps and cuts, increased popularity of online travel agents, and the emergence of automated travel management systems. These developments forced many travel agents to exit the market or to surrender to lower profitability. This case study examines how a mega-agency responded to these threats, the obstacles ...
Mechanisms which produce a mixing in the solar core, based on the original idea of the “solar spoon” (Dilke & Gough 1972), for explaining the neutrino problem have recently been ruled out by Bahcall & Kumar (1993). We therefore revisit the original work of Rosenbluth & Bahcall (1973) on the nonspherical thermal instabilities in the solar core, introducing some improvements. The authors found th...
We calculate thermodynamic quantities of hydrophobic-polar (HP) lattice proteins by means of a multicanonical chain-growth algorithm that connects the new variants of the Pruned-Enriched Rosenbluth Method and flat histogram sampling of the entire energy space. Since our method directly simulates the density of states, we obtain results for thermodynamic quantities of the system for all temperat...
Via nonlinear gyrokinetic simulations, microturbulent transport is investigated for electromagnetic Trapped Electron Mode (TEM) and Ion Temperature Gradient (ITG) tokamak core turbulence with β up to and beyond the Kinetic Ballooning Mode (KBM) threshold. Deviations from linear expectations are explained by zonal flow activity in the TEM case. For the ITG scenario, β-induced changes are observe...
