6 results for “magnetic losses”
(EMPIR 19ENG06 HEFMAG) Data sets of measurements of magnetic loss and complex permeability on amorphous and nanocrystalline samples up to the MHz range
<p>We measured the magnetic losses and the complex permeability of amorphous and nanocrystalline ribbons from DC to 1 GHz by combined application of fluxmetric and transmission line methods. Two transverse field annealed Co-based amorphous alloys, ~13 µm and ~25 µm tick and two nanocrystalline Finemet type alloys, ~13 µm and ~20 µm tick, endowed with defined transverse magnetic anisotropy, were characterized. </p>

Quantifying the effect of magnetic field line curvature scattering on the loss of ring current ions
<p>The datas used for the paper of "Quantifying the effect of magnetic field line curvature scattering on the loss of ring current ions"</p> <p>The file contains three folders data_kp4, data_kp5, data_kp6 for the simulations under Kp index of 4,5 and 6 respectively. Each of them contains subfolders with name including _He_, _o_, and _proton_ for the species of proton, He+ and O+ respectively. Under these subfolders there are several subfolders for the simulations under different initial equatorial x-position at the midnight. Each of them contains folders with name of data appended with numbers. Under these folders there are three important files of ini_params.dat, fin_param.dat, tdrift.dat, screenoutput.txt.</p> <p><strong>init_params.dat </strong>contains ten numbers of: energy in MeV, equatorial pitch angle in degree, initial positions Lx, y, z, radius of curvature <span class="math-tex">\(R_{c}\)</span>, <span class="math-tex">\(\kappa\)</span>, <span class="math-tex">\(\zeta_{1}, \zeta_{2}, \eta\)</span>. The last four parameters are the kappa parameter and the parameters in Young et al. 2002 used for formulating empirical formula for the single field line curvature scattering.</p> <p><strong>fin_params.dat contains five colum data: </strong>particle tag number, status if the particle (0 stay until the end of the simulations, 1 lost to the inner boundary, 2 lost to the outer boundary, 3 stopped as trapped), time of loss in second or end of simulations if stayed until the end, number of mirrorings, <span class="math-tex">\(<\frac{(\frac{\delta \mu}{\mu})^2}{2 t}>\)</span></p> <p><strong>tdrif.dat</strong> contains two column data of : particle tag number and the time in second to complete the first full drift.</p> <p><strong>screenoutput.txt </strong>contains text information of the run</p>

Epub 2019 May 15. PMID: 30957981.</p> <p> </p> <p>This is the abstract:</p> <p><strong>Aim: </strong> To test the hypothesis that deep transcranial magnetic stimulation (dTMS) reduces food craving and causes weight loss via neuromodulation.</p> <p><strong>Materials and methods: </strong> This pilot study was designed as a randomized, double-blind, sham-controlled study. A total of 33 obese people (nine men, 24 women, mean age 48.1 ± 10.6 years, body mass index [BMI] 36.9 ± 4.7 kg/m<sup>2</sup> ) were randomized and completed the study: 13 participants underwent a 5-week treatment with high-frequency (HF) dTMS (18 Hz; HF group), 10 were treated with low-frequency (LF) dTMS (1 Hz; LF group), and 10 were sham-treated (sham group). Food craving, and metabolic and neuro-endocrine variables were evaluated at baseline, after the 5-week treatment, and at follow-up visits (1 month, 6 months, 1 year after the end of treatment).</p> <p><strong>Results: </strong> The mixed-model analysis for repeated measures showed a significant interaction of time and groups for body weight (P = 0.001) and BMI (P = 0.001), with a significant body weight (-7.83 ± 2.28 kg; P = 0.0009) and BMI (-2.83 ± 0.83, P = 0.0009) decrease in the HF versus the sham group. A decreasing trend in food craving in the HF versus the LF and sham groups (P = 0.073) was observed. A significant improvement of metabolic and physical activity variables was found (P < 0.05) in the HF group.</p> <p><strong>Conclusions: </strong> We demonstrated the safety and efficacy of dTMS, in addition to physical exercise and a hypocaloric diet, in reducing body weight for up to 1 year in obese people. We hypothesize that a possible mechanism of HF dTMS treatment is modulation of the dopaminergic pathway and stimulation of physical activity.</p> <p> </p>
