We consider electron transport in a nearly half-metallic ferromagnet, in which the minority spin electrons close to the band edge at the Fermi energy are Anderson-localized due to disorder. For the case of spin-flip scattering of the conduction electrons due to the absorption and emission of magnons, the Boltzmann equation is exactly soluble to the linear order. From this solution we calculate ...

  The flux-pinning mechanism and activation energy of 10 wt % malic acid-doped MgB2 were investigated by measuring of the critical current density and resistivity as a function of magnetic field and temperature. A crossover field, Bsb, was observed from the single vortex to the small vortex bundle pinning regime. For the sintered sample, the temperature dependence of Bsb(T) at low temperature i...

With the development of petroleum in China, most oilfields have entered stage high water cut development. Well ground resistivity method as a new type electric prospecting method, which influence on formation small, measuring low cost advantages, gradually become one key technology remaining oil distribution detection inversion is through observation underground space apparent data reconstructi...

BACKGROUND The traditional technique for subcutaneous implantable cardioverter defibrillator (S-ICD) implantation involves three incisions and a (SC) pocket. An intermuscular (IM) 2-incision has been recently adopted. AIMS We assessed acute defibrillation efficacy (DE) of S-ICD (DE ≤65 J) according to the technique. METHODS analyzed consecutive patients who underwent DE testing at 53 Italian ce...

Chiral molecular crystals built up by chiral molecules without inversion centers have attracted much interest owing to their versatile functionalities related to optical, magnetic, and electrical properties. However, there is a difficulty in chiral crystal growth due to the lack of symmetry. Therefore, we made the molecular design to introduce intermolecular hydrogen bonds in chiral crystals. R...

Magnetotransport measurements are performed on an aluminum thin film grown on a GaAs substrate. A crossover from electron- to hole-dominant transport can be inferred from both longitudinal resistivity and Hall resistivity with increasing the perpendicular magnetic field B. Also, phenomena of localization effects can be seen at low B. By analyzing the zero-field resistivity as a function of temp...

Many papers discuss the Maximum Power Point Tracking (MPPT) control simulation "Perturb and Observe" (P&O), while its realization practice in systems remains a major challenge. The purpose of this research to study experimentally by optimizing wind turbines PMSG connected DC-DC converter (Boost) resistive load. proposed MPPT P&O algorithm modification will be analyzed comparing ...

A rapid and sensitive HPLC method has been developed for the quantification of mirtazapine (MRZ), a noradrenergic and specific serotonergic inhibitor antidepressant (NaSSA) and its two major metabolites N-desmethylmirtazapine (NDM) and 8-hydroxymirtazapine (8-OHM) in human plasma. The separation was achieved using Chromolith C18 column and a mobile phase of acetonitrile: phosphate buffer (pH=3,...
