Condensed matter systems provide alternative `vacua' exhibiting emergent low-energy properties drastically different from those of the standard model. A case in point is quantum electrodynamics (QED) fractionalized topological magnet known as spin ice, whose magnetic monopoles set it apart familiar QED world we live in. Here, show that two greatly differ their fine-structure constant $\alpha$, ...

The structural parameters of a grain dryer are directly related to the its energy consumption and quality formation. Therefore, based on Ergun model, air state uniformity evaluation method, effect changes in ventilation area airflow resistance, drying consumption, efficiency theoretically experimentally studied this work under same initial weight flux. results show that conditions temperatures ...

in this paper, the nonlinear conjugate map based on the conjugate hasofer-lind and rackwitz- fiessler (chl-rf) method is applied to evaluate the reliability index using first order reliability method of the embedded noanocompsite beam, which is made from polymer reinforced with carbon nanotubs (cnts). the structure is simulated with timoshenko beam model. the mori-tanaka model is applied for ca...
