Abstract Accurate and efficient calculation of a transformer's magnetic field is fundamental for the rapid its losses, temperature rise, structural forces. However, existing numerical methods calculating harmonic product‐level transformer are time‐consuming fail to meet requirements digital operations maintenance. To address this, this paper first utilises method obtain snapshot matrix field. Subsequently, response surface model constructed using intrinsic quadrature theory radial basis...

Dark surface waves with photorefractive diffusion and photovoltaic nonlinearities are predicted for the first time. We find it is extraordinary that this type of dark should be in self-focusing media, which very different from solitons or other nonlinear waves. An oscillator model proposed by above phenomenon demonstrated. In an equivalent force function established, whose form determines varieties (bright waves, others).
Background: The combination of inhibitory and facilitatory repetitive transcranial magnetic stimulation (rTMS) can improve motor function stroke patients with undefined mechanism. It has been demonstrated that rTMS exhibits a neuro-modulatory effect by regulating the major neurotransmitter γ-aminobutyric acid (GABA) in other diseases. Objectives: To evaluate combined on GABA primary cortex (M1) for treating dysfunction after acute ischemic stroke. Methods: 44 were randomly divided into two...

We demonstrate highly efficient control of antiferromagnetic (AFM) magnon spins by the interfacial exchange interaction in heterostructures ferrimagnetic yttrium iron garnet (YIG) and AFM ${\mathrm{Cr}}_{2}{\mathrm{O}}_{3}$. At low temperatures, ${\mathrm{Cr}}_{2}{\mathrm{O}}_{3}$ is antiferromagnetically ordered. The exerted YIG lifts degeneracy between modes ${\mathrm{Cr}}_{2}{\mathrm{O}}_{3}$, resulting a net spin polarization current dominated left-handed magnons, even at zero magnetic...
