We report an unexpected sharp peak in the temperature dependence of the magnetoresistance of the reentrant integer quantum Hall states in the second Landau level. This peak defines the onset temperature of these states. We find that in different spin branches the onset temperatures of the reentrant states scale with the Coulomb energy. This scaling provides direct evidence that Coulomb interact...

The possibility of the structural change in YbPd has been investigated by Raman scattering in the temperature range from 4 K to 300 K. One peak was clearly observed around 91 cm−1 below 132 K. This is a clear evidence of a structural change at the transition temperature 132 K from the CsCl structure. The polarization dependence of the 91 cm−1 peak shows that the cubic and tetragonal symmetries ...

A study of the California Sierra Nevada snowpack has been conducted using snow station observations and reanalysis surface temperature data. First-of-the-month snow water equivalent (“SWE”) measurements were combined from two data sets to provide sufficient data from 1930 to 2007. The monthly snapshots are used to calculate peak snow mass timing for each snow season. Since 1930, there has been ...

conclusions there was no difference in clinical outcome after cardiac surgery when we administered an additional dose of methylprednisolone compared to a single dose of methylprednisolone. patients and methods sixty pediatric patients (age < 5years) undergoing cardiopulmonary bypass surgery between september 2011-2012 at imam reza hospital-mashhad were randomly assigned to receive preoperative ...

This paper deals with the effect of process parameters on the peak load and the energy absorption of the expansion of thin walled tubes using a die. The energy absorption and peak load during the expansion process were calculated for various punch angles (α) and with different expansion ratios (rp/ro) at different temperatures (T) by finite element analysis where rp is the punch outer radius an...

We study the statistics of the spacing between Coulomb blockade conductance peaks in quantum dots with large dimensionless conductance g. Our starting point is the ‘‘universal Hamiltonian’’—valid in the g→` limit—which includes the charging energy, the single-electron energies ~described by random matrix theory!, and the average exchange interaction. We then calculate the magnitude of the most ...

Using a heat flow model of a DTA (differential thermal analyzer) and thermal characteristics obtained by fitting experimental results for a pure metal, the response of the DTA is modeled for the melting and solidification of alloys. The enthalpy-temperature relation used for the alloy simulations is obtained by two different methods: 1) equilibrium and Scheil considerations derived solely from ...

We report on a neutron spin echo investigation of the intermediate scale dynamics of polyisobutylene studying both the self-motion and the collective motion. The momentum transfer (Q) dependences of the self-correlation times are found to follow a Q(-2/beta) law in agreement with the picture of Gaussian dynamics. In the full Q range of observation, their temperature dependence is weaker than th...

We report the measurements of the heat capacity of (4)He confined in nanoporous Gelsil glass that has nanopores of 2.5-nm diameter at pressures up to 5.3 MPa. The heat capacity has a broad peak at a temperature much higher than the superfluid transition temperature obtained using the torsional oscillator technique. The peak provides definite thermodynamic evidence for the formation of localized...

This paper presents a parallel approach to estimate the parameters in the heat loading of a district heating system by use of the traditional particle swarm optimisation (TPSO) on the Graphic Processing Unit (GPU) using OpenCL. The running time of the algorithm is greatly reduced compared to running on CPU. The heat load is approximated by the sum of time dependent and temperature dependent com...
