We study magnetization reversal and first order curves for two different magnetic topological semimetals, Co3Sn2S2 Fe3GeTe2, in a wide temperature range. For the reversal, we observe strong dependence of initial (low-temperature) step-like switchings, so inverted hysteresis appears at high temperatures. Usually, is fingerprint material with independent phases, inversion reflects phase interacti...

the three-phase-lag model and green–naghdi theory without energy dissipation are employed to study the deformation of a two-temperature fiber-reinforced medium with an internal heat source that is moving with a constant speed under a hydrostatic initial stress and the gravity field.  the modulus of the elasticity is given as a linear function of the reference temperature. the exact expressions ...

an infinitely long hollow cylinder containing isotropic linear elastic material is considered under the effect of arbitrary boundary stress and thermal condition. the two-dimensional coupled thermoelastodynamic pdes are specified based on equations of motion and energy equation, which are uncoupled using nowacki potential functions. the laplace integral transform and bessel-fourier series are u...

Six forest tree height inversion methods of polarimetric SAR interferometry were validated using repeat pass E-SAR datasets and the corresponding ground measured forest stand height. We show that SINC, three stage full model and three stage SINC inversions have good performance, and the SINC inversion with the first optimum coherence (OPT1) produces the best result among the eleven coherence ty...

Single-crystal X-ray diffraction and specific heat studies establish that strontium hexavanadium undecaoxide, SrV(6)O(11), undergoes a P6(3)/mmc to inversion twinned P6(3)mc structural transition as the temperature is lowered through 322 K. The P6(3)/mmc and P6(3)mc structures have been determined at 353 K and at room temperature, respectively. For the room-temperature structure, seven of the t...

PURPOSE The aim of the current study was to show if contrast-to-noise ratio (CNR) could be improved without loss of diagnostic accuracy if a phase-sensitive inversion recovery (PSIR) single-shot TrueFISP sequence is used at 3.0 T instead of 1.5 T. MATERIAL AND METHODS Ten patients with myocardial infarction were examined on a 1.5 T magnetic resonance (MR) system (Avanto, Siemens Medical Syste...

In self-emulsification higher-energy micrometre and sub-micrometre oil droplets are spontaneously produced from larger ones and only a few such methods are known. They usually involve a one-time reduction in oil solubility in the continuous medium via changing temperature or solvents or a phase inversion in which the preferred curvature of the interfacial surfactant layer changes its sign. Here...

Background In a system of two immiscible liquids, usually water (or an aqueous solution) and an organic liquid (e.g. an oil), there are two general types of dispersions which can be formed depending on the conditions of the system. A water-in-oil (W/O) dispersion is a dispersion formed when the aqueous phase is dispersed in the organic phase and an oil-in-water (O/W) dispersion is a dispersion ...

A new strategy of synthesizing hexagonal upconversion NaYF(4) at low temperature (down to 130 °C) based on Ti(4+) doping-induced cubic-to-hexagonal phase transition in a liquid-solid-solution reaction system is offered.
