We apply the Wang-Landau method to the study of the critical behavior of the three dimensional Random Field Ising Model with a bimodal probability distribution. For high values of the random field intensity we find that the energy probability distribution at the transition temperature is double peaked, suggesting that the phase transition is first order. On the other hand, the transition looks ...

We have previously discussed the classical diffusive system of the bounded one-dimensional multitrap using the transfer-matrix method which is generally applied for studying the energy spectrum of the unbounded quantum Kronig-Penney multibarrier. It was shown, by this method, that for certain values of the relevant parameters the bounded multitrap array have unity transmission and a double-peak...

Time resolved optical emission spectroscopy is employed to study the expansion dynamics of C2 species in a graphite plasma produced during the Nd : YAG ablation. At low laser fluences a single peak distribution with low kinetic energy is observed. At higher fluences a twin peak distribution is found. It has been noted that these double peak time of flight distribution splits into a triple peak ...

In the low dimensional spin systems SrCu2(BO3)2 and CuGeO3 the thermal conductivities along different crystal directions show pronounced double-peak structures and strongly depend on magnetic fields. For SrCu2(BO3)2 the experimental data can be described by a purely phononic heat current and resonant scattering of phonons by magnetic excitations. A similar effect seems to be important in CuGeO3...

Arterial Oxygen Saturation as a Predictor of Acute Mountain Sickness and Summit Success among Mountaineers

In June 2018, the 44th Group of Seven (G7) Summit was held in La Malbaie Province Quebec, Canada. Drawing from geographic and sociological literature on protest social movement policing applying concept scale, we examine techniques summit security deployed for event. Analysing results access to information requests, investigate pre-summit planning as well surveillance operations undertaken by m...
